Развојниот тренд на индустријата за храна за домашни миленици главно се рефлектира во три аспекти: прво, исхрана и здравје. Сопствениците на домашни миленици посветуваат се повеќе внимание на нутритивниот состав на храната за домашни миленици, и производи со природни, без адитиви, функционални (како што е убавината на косата, исхрана на стомакот, контрола на тежината) карактеристиките се попопуларни; второ, диверзификација на видовите производи. Со збогатување на типовите миленици и индивидуалните потреби на сопствениците на домашни миленици, храната за домашни миленици постепено се развива кон сегментација, како храна за домашни миленици за различни возрасти (кученца, возрасни кучиња, стари кучиња), различни раси, и различни физички услови; трето, интелигенција и ефикасност на технологијата за обработка. Со цел да се задоволи побарувачката за производство од големи размери и да се обезбеди стабилност на квалитетот на производот, Претпријатијата за преработка на храна за домашни миленици постојано воведуваат напредна опрема за обработка и интелигентни системи за контрола за да ја подобрат ефикасноста на производството и да ги намалат трошоците за работна сила.
На оваа позадина, Технологија на истиснување на надувување, како основна технологија за преработка на храна за домашни миленици (особено суви надуени производи), стана клучот за одредување на квалитетот на храната за домашни миленици и конкурентноста на претпријатијата. Нашите професионални екструдери за производство на храна за домашни миленици се развиени како одговор на карактеристиките на индустријата и побарувачката на пазарот, што може ефикасно да ги реши болките во преработката на храна за домашни миленици и да им помогне на претпријатијата да постигнат висококвалитетно и ефикасно производство.
1.2 Класификација на храна за домашни миленици и карактеристики на нејзината обработка
Храната за домашни миленици има различни методи на класификација, кои можат да се поделат на различни видови според технологијата на обработка, содржина на вода, форма и употреба на производот. Меѓу нив, според технологијата на обработка и содржината на вода, храна за домашни миленици е главно поделена на суви надуени производи, полувлажни производи, меки надуени производи, влажни конзервирани производи и закуски (или третира). Секој тип на храна за домашни миленици има свои уникатни карактеристики на обработка и барања за опрема, како што следува:
1.2.1 Суви надуени производи:
Сувата надуена храна за домашни миленици е најчестиот вид храна за домашни миленици, со содржина на вода од 10%-12%. Нејзините главни суровини вклучуваат месни оброци, рибен оброк, житарки (пченка, пченица, оризот), оброк од соја, витамини, минерали и други адитиви. Процесот на преработка на суви надуени производи е тесно поврзан со процесот на надувување, што бара употреба на опрема за истиснување за да се преработат суровините во зрнести производи со еднаква големина, остар вкус и добра вкусност. Карактеристиките на сувите надуени производи се долг рок на траење, практично складирање и транспорт, и ниски трошоци за производство, кои се погодни за големо производство и популарни меѓу сопствениците на домашни миленици.
Клучното барање за преработка на сувите надуени производи е дека суровините треба да бидат целосно надуени, така што скробот во суровините целосно се желатинизира, што е погодно за варење и апсорпција на домашните миленици. Во исто време, производот треба да има одредена цврстина и острина за да ги задоволи потребите за џвакање на домашните миленици и да помогне во чистењето на нивните заби. Ова поставува високи барања за притисокот на истиснување, температура и брзина на завртката на екструдерот.
1.2.2 Полувлажни производи:
Полувлажната храна за домашни миленици има содржина на вода од 25%-35%, кој е помеѓу суви и влажни производи. Неговите суровини се слични на сувите надуени производи, но повеќе навлажнувачи (како што е пропилен гликол, сорбитол) се додаваат за да се одржи мекоста и влажноста на производот. Процесот на преработка на полувлажни производи, исто така, има потреба од третман на пуфинг, но степенот на надуеност е помал од оној на сувите производи. Производот има карактеристики на мек вкус и добра вкусност, кој е погоден за домашни миленици со слаба способност за џвакање (како што се постарите миленичиња, болни миленичиња).
Тешкотијата на преработка на полувлажни производи лежи во контролата на содржината на вода и спречување на влошување на производот. Затоа, во процесот на обработка, потребно е строго да се контролираат температурата и влажноста на секоја врска, и изберете соодветни конзерванси и навлажнувачи за да се обезбеди рок на траење на производот.
1.2.3 Меки надуени производи:
Мека надуена храна за домашни миленици има содржина на вода од 15%-25%, кој е производ помеѓу суви надуени и полувлажни производи. Нејзиниот процес на обработка е сличен на оној на сувите надуени производи, но формулата и параметрите на истиснување се прилагодени за да го направат производот мек и еластичен. Меки надуени производи ги комбинираат предностите на сувите и полувлажните производи, со добра вкусност и лесно варење, кој е погоден за различни домашни миленици.
1.2.4 Влажни конзервирани производи:
Влажната конзервирана храна за домашни миленици има содржина на вода повеќе од 70%, главно се користи свежо месо, риба, зеленчук и други суровини, кои се обработуваат со готвење, конзервирање, стерилизација и други процеси. Различно од другите видови производи, на влажните конзервирани производи не им е потребен третман на пуфинг, а нивните основни врски за обработка се готвење и стерилизација. Производот има карактеристики на богата исхрана, силна вкусност и висока содржина на влага, кој е погоден за домашни миленици кои не сакаат да пијат вода или имаат потреба од дополнителна исхрана.
Клучот за преработка на влажни конзервирани производи е да се обезбеди свежина и безбедност на суровините, и строго контролирајте ја температурата и времето на стерилизација за да ги убиете штетните бактерии во производот и да го продолжите рокот на траење. Во исто време, потребно е да се осигура дека нутритивните компоненти на производот не се губат за време на процесот на готвење и стерилизација.
1.2.5 Закуски за домашни миленици (или Третира):
Закуски за домашни миленици се помошна храна за домашни миленици, главно се користи за наградување на домашни миленици, подобрување на нивното расположение и дополнување на исхраната. Видовите на закуски за домашни миленици се разновидни, вклучително и надуени грицки, закуски од сушено месо, отсечени закуски, стоматолошки закуски, итн. Меѓу нив, надуените грицки заземаат голем дел, а процесот на нивна обработка е сличен на сувите надуени производи, но формулата е попрефинета, и се додаваат повеќе ароматични средства и функционални адитиви за да се задоволат вкусот и функционалните потреби на домашните миленици.
Закуски за домашни миленици имаат високи барања за вкус, изглед и функционалност. На пример, забните грицки треба да имаат одредена цврстина и текстура за да помогнат во чистењето на забите на домашно милениче и да се спречи забен камен; грицките за разубавување на косата треба да додадат состојки како лецитин за да помогнат во подобрувањето на квалитетот на косата на домашно милениче. Ова бара екструдерот да има добра флексибилност и приспособливост за да ги задоволи потребите за обработка на различни видови закуски.
Вреди да се напомене дека освен за конзервирани производи, повеќето видови храна за домашни миленици се тесно поврзани со процесот на пуфкање. Пуфкањето не е само основниот дел од преработката на храна за домашни миленици, но и директно влијае на квалитетот, вкус, исхрана и сварливост на храната за домашни миленици. Затоа, изборот на вистинската опрема за истиснување и совладувањето на научната технологија за истиснување се клучни за претпријатијата за преработка на храна за домашни миленици.
2. Основна технологија за преработка на храна за домашни миленици: Технологија на истиснување на издувување
Технологијата за издувување со истиснување е клучна технологија за обработка која интегрира мешање, месење, греење, истиснување и пуфкање. Широко се користи во производството на храна за домашни миленици поради предностите на високата производна ефикасност, добар квалитет на производот, силна приспособливост на суровините и широк опсег на примена. Во преработката на храна за домашни миленици, Технологијата на истиснување главно се користи за да се реализира пуфкање на суровините, направете го скробот да се желатинизира, денатурата на протеините, и ја подобрува вкусноста и сварливоста на производот. Во исто време, може да убие и штетни бактерии во суровините, обезбеди безбедност на храна за домашни миленици.
2.1 Карактеристики на суровините за храна за домашни миленици и барања за опрема за екструзија
Суровините на храната за домашни миленици се главно месни производи (како што е месен оброк, рибен оброк, свежо месо), житарки, оброк од соја, витамини, минерали и други адитиви. Меѓу нив, месните производи заземаат голем дел, правејќи го производот да има силен вискозитет. Оваа карактеристика поставува посебни барања за опремата за истиснување:
Екструдерите со еден шраф не се погодни за економско производство на храна за домашни миленици. Бидејќи екструдерот со една завртка има тесен опсег на смолкнување, слаб капацитет на пумпање и нема ефект на самочистење. При обработка на вискозни материјали како што се месни производи, лесно е да се предизвика акумулација на материјалот, блокада и нерамномерно мешање во цевката на екструдерот, што не само што влијае на ефикасноста на производството, но доведува и до нестабилен квалитет на производот. Покрај тоа, екструдерот со една завртка има висока потрошувачка на енергија при обработка на суровини со висока содржина на масти и протеини, со што се зголемуваат производните трошоци на претпријатијата.
Екструдери со две завртки, од друга страна, имаат очигледни предности во производството на храна за домашни миленици. Тие имаат поширок опсег на смолкнување, поефективен ефект на пумпање и ефект на самочистење, што може ефективно да ги реши проблемите со вискозноста и акумулацијата на материјалот. Екструдерот со две завртки може да го реализира еднообразното мешање, месење и истиснување на материјали, дури и при преработка на суровини со висока содржина на масти и свежо месо, исто така може да обезбеди стабилно производство и постојан квалитет на производот. Затоа, во вистинското производство на храна за домашни миленици, Екструдерите со двојни завртки станаа главно средство за надувување храна за домашни миленици, and are widely used in the production of dry puffed products, полувлажни производи, soft puffed products and pet snacks.
2.2 Working Principle of Screw Extrusion Puffing
The screw extrusion puffing process of pet food is a complex physical and chemical process, which involves the interaction of multiple factors such as temperature, притисок, shear force and time. The specific working principle is as follows:
Прво, raw material pretreatment. The powdery raw materials containing a certain amount of starch (more than 20%) are mixed uniformly according to the formula, and then sent to the tempering device for tempering treatment. The purpose of tempering is to adjust the moisture content and temperature of the materials, so that the materials can reach the ideal state before entering the extruder. Generally, the moisture content of the materials after tempering is controlled at 10%～27%, and the temperature is raised to 70～98℃. During the tempering process, the materials absorb water evenly, which is conducive to the subsequent gelatinization of starch and denaturation of protein, and can also reduce the wear of the extruder screw and barrel.
Второ, extrusion and heating. The tempered materials enter the screw extrusion cavity through the feeding device. The screw extrusion cavity is composed of a screw and a barrel, and the volume of the extrusion cavity gradually decreases along the axis direction. When the screw rotates, it pushes the materials forward continuously, and the materials are gradually compressed under the action of the screw and the barrel, а притисокот во шуплината за истиснување постепено се зголемува. Односот на компресија (односот на волуменот на материјалот на крајот на напојувањето со волуменот на крајот на истиснување) може да достигне 4-10, што варира во зависност од видот на храна за домашни миленици и формулата на суровините.
За време на процесот на туркање и екструдирање со завртката, материјалите се подложени на силна сила на смолкнување и сила на триење. Силата на смолкнување се генерира од релативното движење помеѓу завртката и цевката, како и помеѓу летовите на завртката. Може да ги скрши честичките од материјалите, направи суровините и адитивите да се мешаат порамномерно, и промовира желатинизација на скроб и денатурација на протеини. Силата на триење се создава помеѓу материјалите и внатрешниот ѕид на бурето, како и помеѓу материјалните честички, што може да генерира многу топлина, што е погодно за загревање на материјалите. Покрај тоа, според потребите за обработка, пареата може да тече низ обвивката на бурето за да ги загрее материјалите помеѓу ѕидовите, така што материјалите во шуплината за истиснување се во состојба на висока температура и висок притисок. Температурата во шуплината на истиснување генерално се контролира на 120-180℃, а притисокот се контролира на 2~10MPa.
Трето, желатинизација на скроб и денатурација на протеини. Под дејство на висока температура, висок притисок и сила на смолкнување, скробот во материјалите апсорбира вода и се шири, кристалната структура е уништена, и се претвора во аморфна состојба, што се нарекува желатинизација на скроб. Желатинизацијата со скроб може да ја подобри сварливоста на храната за домашни миленици, бидејќи желатинизираниот скроб полесно се разложува од дигестивните ензими на домашните миленици. Во исто време, желатинизираниот скроб исто така може да ја подобри вискозноста и силата на врзување на материјалите, правејќи ги екструдираните производи да имаат добра форма и текстура.
Покрај желатинизацијата со скроб, протеинот во материјалите исто така ќе претрпи денатурација под дејство на висока температура и висок притисок. Протеинската денатурација се однесува на промена на просторната структура на протеинските молекули без промена на примарната структура, што може да ја подобри растворливоста и сварливоста на протеините, и направи храната за домашни миленици да има подобра вкусност. Во исто време, денатурираниот протеин може да формира и мрежна структура, кој може да го обвитка скробот и другите компоненти, helping to maintain the shape of the puffed product.
Fourth, puffing and shaping. When the materials in the high-temperature and high-pressure state are pushed to the die head by the screw and extruded from the die hole at a high speed, the temperature and pressure of the materials drop sharply because they suddenly leave the extrusion cavity and enter the normal atmospheric environment. Under the combined action of pressure difference and temperature difference, the water in the materials evaporates rapidly, the volume of the materials expands rapidly (the expansion rate can reach 2～8 times), and the materials are dehydrated and solidified quickly to form a porous, crisp or soft puffed product.
After extrusion from the die hole, the puffed materials are cut into short particles of uniform length by the cutting device (rotary knife) installed at the die head. The length of the particles can be adjusted by changing the speed of the rotary knife to meet the requirements of different types of pet food. На пример, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Fifth, post-processing. The extruded puffed particles need to go through post-processing links such as drying, ладење, seasoning and packaging to become the final pet food products. Drying is to reduce the water content of the particles to the standard range (10%-12% for dry products), so as to extend the shelf life of the product. Cooling is to reduce the temperature of the dried particles to room temperature, спречете го производот да се згусне и да се расипе. Леќата е да се прскаат арома агенти, привлечни и други адитиви на површината на честичките за да се подобри вкусноста на производот. Пакувањето е да се пакуваат зачинетите честички во кеси или лименки за да се обезбеди хигиена и безбедност на производот и да се олесни складирањето и транспортот.
2.3 Клучни фактори кои влијаат на ефектот на издувување со истиснување на завртката
Ефектот на истиснување на завртката директно влијае на квалитетот на храната за домашни миленици. Постојат многу фактори кои влијаат на ефектот на пуфинг, главно вклучувајќи ги карактеристиките на суровината, параметри за калење, параметри на истиснување и структура на главата на матрицата. Совладувањето на овие клучни фактори и правењето научни приспособувања може да обезбеди стабилност на ефектот на надувување и конзистентност на квалитетот на производот.
2.3.1 Raw Material Characteristics:
The type, големина на честички, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. На пример, the starch content of raw materials directly affects the expansion rate of the product. The higher the starch content (within a certain range), the better the puffing effect, and the larger the expansion rate of the product. The particle size of raw materials should be uniform, generally 80-100 mesh. If the particle size is too large, the materials are not easy to be mixed uniformly and plasticized fully, which affects the puffing effect; if the particle size is too small, it is easy to cause material blockage and increase energy consumption. The moisture content of raw materials before tempering should be controlled at 8%-12%. If the moisture content is too high, the materials are easy to stick to the screw and barrel, affecting the extrusion and puffing; if the moisture content is too low, the shear force and friction force between the materials are insufficient, and the starch gelatinization is incomplete, resulting in poor puffing effect.
2.3.2 Tempering Parameters:
Tempering parameters mainly include tempering temperature, tempering time and moisture content after tempering. The tempering temperature is generally 70～98℃. If the tempering temperature is too low, the materials cannot absorb water evenly, and the starch gelatinization is insufficient; if the tempering temperature is too high, the materials may be caked in advance, affecting the subsequent extrusion. The tempering time is generally 2-5 minutes, which should be adjusted according to the type of raw materials and the moisture content. The moisture content after tempering is 10%～27%, which varies according to the type of pet food. На пример, the moisture content of dry puffed products after tempering is generally 15%-20%, while that of semi-wet products is 22%-27%.
2.3.3 Extrusion Parameters:
Extrusion parameters are the most important factors affecting the puffing effect, mainly including screw speed, extrusion temperature and extrusion pressure. Screw speed generally ranges from 100 до 600 rpm. The higher the screw speed, the greater the shear force and friction force received by the materials, the higher the extrusion temperature and pressure, and the better the puffing effect. Сепак, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, што резултира со нецелосно желатинизирање на скроб и нерамномерно мешање; ако брзината на завртката е премногу мала, силата на смолкнување и силата на триење се недоволни, а ефектот на пуфкање е слаб.
Температурата на истиснување генерално се контролира на 120-180℃, кој е поделен на три дела: дел за хранење, дел за топење и дел за хомогенизација. Температурата на делот за хранење е пониска (70~ 90 ℃), што е главно за да се спречи згрутчувањето на материјалите и да се обезбеди непречено хранење; температурата на делот за топење е средна (120~150℃), што е главно за промовирање на топење и пластифицирање на материјалите; температурата на делот за хомогенизација е повисока (150~180℃), што е главно за да се обезбеди еднообразно мешање и целосна желатинизација на материјалите.
Extrusion pressure is generally 2～10MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the puffing effect, but if the pressure is too high, it will increase the energy consumption and wear of the equipment; if the pressure is too low, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Die Head Structure:
The die head structure mainly includes the number, shape and size of die holes. The shape of the die hole determines the cross-sectional shape of the puffed product, such as circular, square, triangular and other shapes. The size of the die hole determines the initial diameter of the product. The smaller the die hole size, the greater the extrusion pressure, and the better the puffing effect, but the production capacity will be reduced. The number of die holes affects the production capacity. The more the number of die holes, the higher the production capacity, but it is necessary to ensure that the pressure distribution is uniform, so as to avoid uneven puffing of the product.
3. Our Extruders: Advantages and Product Series for Pet Food Production

Our extruders have the advantages of low operating cost, wide application range, advanced technology and reliable process control, which can meet the processing needs of various types of pet food and help enterprises improve production efficiency and product quality.
3.1 Main Advantages of Our Extruders
3.1.1 Low Lifetime Operating Cost:
We focus on the durability and economy of the equipment, and adopt high-quality materials and advanced manufacturing technology to ensure that the extruder has a long service life and low operating cost. The inner wall of the barrel is made of high-quality wear-resistant alloy steel, which has extremely strong wear resistance and can effectively resist the wear caused by the friction between the materials (especially the materials containing hard particles such as bone meal) and the barrel. This greatly extends the service life of the barrel, reducing the frequency of barrel replacement and the maintenance cost of the equipment.
Покрај тоа, we also provide professional barrel wear measurement services. Our technical team will regularly or irregularly detect the wear of the barrel for customers, accurately judge the wear degree of the barrel, and provide professional suggestions on barrel replacement. This ensures that customers only replace the barrel when it is really needed, avoiding unnecessary waste and reducing the operating cost of the equipment. Во исто време, the screw of our extruder is also made of wear-resistant alloy steel, which has good corrosion resistance and wear resistance, and can adapt to the processing of high-fat, high-protein and high-salt raw materials.
3.1.2 Wide Application Range:
Our twin-screw extruders have strong adaptability and can meet the processing needs of various types of pet food, including dry puffed products, полувлажни производи, меки надуени производи, pet snacks and other products. The extruder is equipped with a high-torque drive system, variable screw speed and pressure variable control device, which provides excellent flexibility for customers, and can be adjusted according to different process requirements and raw material formulas to achieve the best processing effect.
The modular design of the extruder is another major feature that expands its application range. The screw, буре, die head and other components of the extruder adopt a modular design, which can be freely combined and replaced according to the customer’s specific application needs. На пример, when processing dry puffed products, customers can choose a screw with a high compression ratio and a die head with small die holes; when processing semi-wet products, they can choose a screw with a medium compression ratio and a die head with large die holes. This modular design not only improves the flexibility and adaptability of the equipment, but also reduces the cost of equipment transformation when customers adjust their product types.
3.1.3 Advanced Technology and Reliable Process Control:
Our extruders adopt the most advanced intelligent control technology, which can realize the precise control of the entire processing process, ensuring the consistency of the final product quality. The extruder is equipped with an intelligent formula memory system, which can store multiple sets of product formulas and processing parameters. When customers produce different products, they only need to call the corresponding formula and parameters, without repeated debugging, which not only saves time and improves production efficiency, but also maximizes the reduction of process errors and operator errors.
The intelligent control system also has real-time monitoring and alarm functions. It can monitor key parameters such as extrusion temperature, extrusion pressure, брзина на завртката, material moisture content and production capacity in real time. If any parameter exceeds the set range, the system will issue an alarm prompt in time, and even automatically shut down the equipment if necessary, to avoid equipment failure and product quality problems. Покрај тоа, the control system adopts a touch screen operation interface, which is simple and intuitive, easy to operate, and can reduce the professional requirements for operators.
3.1.4 Good Product Quality Stability:
