1.2 Класификация на храните за домашни любимци и характеристиките на тяхната обработка
Храната за домашни любимци има различни методи за класификация, които могат да бъдат разделени на различни видове според технологията на обработка, водно съдържание, форма на продукта и употреба. Сред тях, според технологията на обработка и водното съдържание, храната за домашни любимци се разделя главно на сухи надути продукти, полумокри продукти, меки бухнали продукти, мокри консервирани продукти и закуски (или лакомства). Всеки вид храна за домашни любимци има свои уникални характеристики на обработка и изисквания към оборудването, както следва:
1.2.1 Сухи бухнали продукти:
Сухата надута храна за домашни любимци е най-често срещаният вид храна за домашни любимци, с водно съдържание от 10%-12%. Основните му суровини включват месно брашно, рибно брашно, зърнени храни (царевица, пшеница, ориз), соев шрот, витамини, минерали и други добавки. Процесът на обработка на сухи бухнали продукти е тясно свързан с процеса на бухване, което изисква използването на екструзионно издухващо оборудване за обработка на суровините в гранулирани продукти с еднакъв размер, свеж вкус и добър вкус. Характеристиките на сухите бухнали продукти са дълъг срок на годност, удобно съхранение и транспортиране, и ниска производствена цена, които са подходящи за мащабно производство и популярни сред собствениците на домашни любимци.
Основното изискване за обработка на сухите бухнали продукти е, че суровините трябва да бъдат напълно бухнали, така че нишестето в суровините да е напълно желатинизирано, което е благоприятно за храносмилането и усвояването на домашни любимци. В същото време, продуктът трябва да има определена твърдост и хрупкавост, за да отговори на дъвкателните нужди на домашните любимци и да помогне за почистването на зъбите им. Това поставя високи изисквания към налягането при екструдиране, температура и скорост на шнека на екструдера.
1.2.2 Полумокри продукти:
Полумократа храна за домашни любимци има водно съдържание от 25%-35%, което е между сухи и мокри продукти. Неговите суровини са подобни на сухи бухнали продукти, но повече овлажнители (като пропилей гликол, сорбитол) се добавят, за да поддържат мекотата и влажността на продукта. Процесът на обработка на полумокрите продукти също се нуждае от обработка с издухване, но степента на издуване е по-ниска от тази на сухите продукти. Продуктът има характеристиките на мек вкус и добър вкус, който е подходящ за домашни любимци с лоша дъвкателна способност (като възрастни домашни любимци, болни домашни любимци).
Трудността при обработката на полумокрите продукти се състои в контрола на водното съдържание и предотвратяването на влошаване на продукта. Следователно, в процеса на обработка, необходимо е стриктно да се контролира температурата и влажността на всяка връзка, и изберете подходящи консерванти и овлажнители, за да осигурите срока на годност на продукта.
1.2.3 Меки надути продукти:
Меката надута храна за домашни любимци има водно съдържание от 15%-25%, който е продукт между сухи бухнали и полумокри продукти. Процесът на обработка е подобен на този на сухите бухнали продукти, но формулата и параметрите на екструдиране са коригирани, за да направят продукта мек и еластичен. Меките бухнали продукти съчетават предимствата на сухите и полумокрите продукти, с добър вкус и лесно смилане, който е подходящ за различни домашни любимци.
1.2.4 Мокри консервирани продукти:
Мократа консервирана храна за домашни любимци има съдържание на вода повече от 70%, основно с прясно месо, риба, зеленчуци и други суровини, които се обработват чрез варене, консервиране, стерилизация и други процеси. Различен от другите видове продукти, мокрите консервирани продукти не се нуждаят от обработка с бухване, и техните основни звена за обработка са готвене и стерилизация. Продуктът има характеристиките на богато хранене, силен вкус и високо съдържание на влага, който е подходящ за домашни любимци, които не обичат да пият вода или имат нужда от допълнително хранене.
Ключът към обработката на мокри консервирани продукти е да се гарантира свежестта и безопасността на суровините, и стриктно контролирайте температурата и времето за стерилизация, за да убиете вредните бактерии в продукта и да удължите срока на годност. В същото време, необходимо е да се гарантира, че хранителните компоненти на продукта не се губят по време на процеса на готвене и стерилизация.
1.2.5 Закуски за домашни любимци (или лакомства):
Пет снаксовете са спомагателна храна за домашни любимци, използва се главно за награждаване на домашни любимци, подобряват настроението си и допълват храненето. Видовете закуски за домашни любимци са разнообразни, включително бухнали закуски, закуски със сушено месо, резки закуски, зъболекарски закуски, и т.н. Сред тях, бухналите закуски представляват голяма част, и процесът им на обработка е подобен на сухите бухнали продукти, но формулата е по-рафинирана, и повече ароматизатори и функционални добавки се добавят, за да отговорят на вкусовите и функционални нужди на домашните любимци.
Закуските за домашни любимци имат високи изисквания към вкуса, външен вид и функционалност. например, зъбните закуски трябва да имат определена твърдост и текстура, за да помогнат за почистването на зъбите на домашния любимец и да предотвратят зъбния камък; закуските за разкрасяване на косата трябва да добавят съставки като лецитин, за да подобрят качеството на косата на домашния любимец. Това изисква екструдерът да има добра гъвкавост и възможност за настройка, за да отговори на нуждите за обработка на различни видове закуски.
It is worth noting that except for canned products, most types of pet food are closely related to the puffing process. Puffing is not only the core part of pet food processing, but also directly affects the quality, taste, nutrition and digestibility of pet food. Следователно, choosing the right extrusion equipment and mastering the scientific extrusion technology are crucial for pet food processing enterprises.
2. Core Technology of Pet Food Processing: Extrusion Puffing Technology
Extrusion puffing technology is a key processing technology integrating mixing, месене, отопление, extrusion and puffing. It has been widely used in the production of pet food due to its advantages of high production efficiency, добро качество на продукта, силна адаптивност към суровините и широк диапазон на приложение. In the processing of pet food, extrusion technology is mainly used to realize the puffing of raw materials, make the starch gelatinize, денатурирането на протеина, и подобряване на вкуса и смилаемостта на продукта. В същото време, може също да убие вредните бактерии в суровините, гарантира безопасността на храната за домашни любимци.
2.1 Характеристики на суровините за храна за домашни любимци и изисквания към оборудването за екструдиране
Суровините за храна за домашни любимци са предимно месни продукти (като месно брашно, рибно брашно, прясно месо), зърнени храни, соев шрот, витамини, минерали и други добавки. Сред тях, месните продукти представляват голяма част, правейки продукта силен вискозитет. Тази характеристика поставя специални изисквания към оборудването за екструдиране:
Едношнековите екструдери не са подходящи за икономично производство на храна за домашни любимци. Тъй като едношнековият екструдер има тесен диапазон на срязване, слаб изпомпващ капацитет и липса на самопочистващ ефект. При обработка на вискозни материали като месни продукти, лесно е да се предизвика материално натрупване, запушване и неравномерно смесване в цевта на екструдера, което не само влияе върху ефективността на производството, но води и до нестабилно качество на продукта. Освен това, едношнековият екструдер има висока консумация на енергия при обработка на суровини с високо съдържание на мазнини и протеини, което увеличава производствените разходи на предприятията.
Двушнекови екструдери, от друга страна, имат очевидни предимства в производството на храни за домашни любимци. Те имат по-широк диапазон на срязване, по-ефективен изпомпващ ефект и самопочистващ ефект, което може ефективно да реши проблемите с вискозитета и натрупването на материала. Двушнековият екструдер може да реализира равномерното смесване, месене и екструдиране на материали, дори при обработка на суровини с високо съдържание на мазнини и прясно месо, може също така да осигури стабилно производство и постоянно качество на продукта. Следователно, в действителното производство на храна за домашни любимци, двушнековите екструдери се превърнаха в основното средство за раздуване на храна за домашни любимци, и се използват широко в производството на сухи бухнали продукти, полумокри продукти, меки бухнали продукти и закуски за домашни любимци.
2.2 Принцип на работа на винтовото екструдиране
Процесът на шнеково екструдиране на храна за домашни любимци е сложен физичен и химичен процес, което включва взаимодействието на множество фактори като температура, налягане, сила на срязване и време. Конкретният принцип на работа е следният:
Първо, предварителна обработка на суровината. Прахообразните суровини, съдържащи определено количество нишесте (повече от 20%) се смесват равномерно по формулата, и след това се изпраща до устройството за темпериране за обработка на темпериране. Целта на темперирането е да се регулира съдържанието на влага и температурата на материалите, така че материалите да могат да достигнат идеалното състояние, преди да влязат в екструдера. Общо взето, съдържанието на влага в материалите след темпериране се контролира при 10% ~ 27%, и температурата се повишава до 70 ~ 98 ℃. По време на процеса на темпериране, материалите абсорбират водата равномерно, което е благоприятно за последващо желатинизиране на нишестето и денатуриране на протеина, и може също така да намали износването на шнека и цевта на екструдера.
Второ, екструдиране и нагряване. Закалените материали навлизат в кухината на винтовата екструзия през захранващото устройство. Шнековата екструзионна кухина се състои от винт и цилиндър, и обемът на екструзионната кухина постепенно намалява по посока на оста. Когато винтът се върти, тя избутва материалите непрекъснато напред, и материалите постепенно се компресират под действието на винта и цевта, и налягането в екструзионната кухина постепенно се увеличава. Степента на компресия (съотношението на обема на материала в края на захранването към обема в края на екструзията) can reach 4～10, която варира според вида на храната за домашни любимци и формулата на суровините.
По време на процеса на избутване и екструдиране от винта, материалите са подложени на силна сила на срязване и сила на триене. Силата на срязване се генерира от относителното движение между винта и цевта, както и между винтовите полета. Може да счупи частиците на материалите, направете суровините и добавките да се смесват по-равномерно, и насърчават желатинизацията на нишестето и денатурирането на протеина. Силата на триене се генерира между материалите и вътрешната стена на цевта, както и между материалните частици, което може да генерира много топлина, което благоприятства нагряването на материалите. Освен това, според нуждите за обработка, steam can flow through the barrel jacket to heat the materials between the walls, so that the materials in the extrusion cavity are in a high-temperature and high-pressure state. The temperature in the extrusion cavity is generally controlled at 120～180℃, and the pressure is controlled at 2～10MPa.
трето, starch gelatinization and protein denaturation. Under the action of high temperature, high pressure and shear force, the starch in the materials absorbs water and expands, the crystal structure is destroyed, and it is converted into an amorphous state, which is called starch gelatinization. Starch gelatinization can improve the digestibility of pet food, because the gelatinized starch is easier to be decomposed by the digestive enzymes of pets. В същото време, желатинизираното нишесте може също да подобри вискозитета и силата на свързване на материалите, правене на екструдираните продукти с добра форма и текстура.
В допълнение към желатинирането на нишестето, протеинът в материалите също ще претърпи денатурация под действието на висока температура и високо налягане. Протеиновата денатурация се отнася до промяната на пространствената структура на протеиновите молекули без промяна на първичната структура, което може да подобри разтворимостта и смилаемостта на протеина, и правят храната за домашни любимци по-добра вкусова. В същото време, денатурираният протеин също може да образува мрежеста структура, който може да увие нишестето и други компоненти, помагайки за поддържане на формата на бухналия продукт.
Четвърто, puffing and shaping. Когато материалите в състояние на висока температура и високо налягане се избутват към главата на матрицата от винта и се екструдират от отвора на матрицата с висока скорост, температурата и налягането на материалите падат рязко, защото те внезапно напускат екструзионната кухина и навлизат в нормалната атмосферна среда. Под комбинираното действие на разликата в налягането и температурната разлика, водата в материалите се изпарява бързо, обемът на материалите се разширява бързо (скоростта на разширяване може да достигне 2～8 пъти), и материалите се дехидратират и втвърдяват бързо, за да образуват пореста, хрупкав или мек бухнал продукт.
След екструдиране от отвора на матрицата, надутите материали се нарязват на къси частици с еднаква дължина от режещото устройство (въртящ се нож) инсталиран на главата на матрицата. Дължината на частиците може да се регулира чрез промяна на скоростта на въртящия се нож, за да отговори на изискванията на различните видове храни за домашни любимци. например, частиците храна за кученца са по-малки и по-къси, докато частиците на храната за възрастни кучета са по-големи и по-дълги.
Пето, последваща обработка. Екструдираните надути частици трябва да преминат през връзки за последваща обработка, като сушене, охлаждане, подправки и опаковки, за да станат крайните хранителни продукти за домашни любимци. Сушенето е да се намали водното съдържание на частиците до стандартния диапазон (10%-12% за сухи продукти), така че да удължите срока на годност на продукта. Охлаждането е да се намали температурата на изсушените частици до стайна температура, предотвратяване на слепване и разваляне на продукта. Подправката е да се пръскат ароматизатори, attractants and other additives on the surface of the particles to improve the palatability of the product. Packaging is to pack the seasoned particles into bags or cans to ensure the hygiene and safety of the product and facilitate storage and transportation.
2.3 Key Factors Affecting Screw Extrusion Puffing Effect
The effect of screw extrusion puffing directly affects the quality of pet food. There are many factors affecting the puffing effect, главно включително характеристики на суровините, tempering parameters, параметри на екструдиране и структура на главата на матрицата. Mastering these key factors and making scientific adjustments can ensure the stability of the puffing effect and the consistency of product quality.
2.3.1 Характеристики на суровината:
Типът, размер на частиците, съдържанието на влага и хранителният състав на суровините оказват голямо влияние върху ефекта на издухване. например, съдържанието на нишесте в суровините пряко влияе върху степента на разширяване на продукта. Колкото по-високо е съдържанието на нишесте (within a certain range), толкова по-добър е ефектът на издухване, и колкото по-голяма е степента на разширение на продукта. Размерът на частиците на суровините трябва да бъде еднакъв, като цяло 80-100 мрежа. Ако размерът на частиците е твърде голям, материалите не се смесват лесно и се пластифицират напълно, което влияе върху ефекта на издухване; ако размерът на частиците е твърде малък, лесно е да се причини блокиране на материала и да се увеличи консумацията на енергия. Съдържанието на влага в суровините преди темперирането трябва да се контролира на 8%-12%. Ако съдържанието на влага е твърде високо, 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 минути, 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. например, 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, главно включително скоростта на винта, extrusion temperature and extrusion pressure. Screw speed generally ranges from 100 към 600 об/мин. The higher the screw speed, толкова по-голяма е силата на срязване и силата на триене, получени от материалите, the higher the extrusion temperature and pressure, and the better the puffing effect. Въпреки това, ако скоростта на винта е твърде висока, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete starch gelatinization and uneven mixing; ако скоростта на винта е твърде ниска, силата на срязване и силата на триене са недостатъчни, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: секция за хранене, melting section and homogenizing section. Температурата на секцията за хранене е по-ниска (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; the temperature of the melting section is medium (120～150℃), which is mainly to promote the melting and plasticization of the materials; the temperature of the homogenizing section is higher (150～180℃), which is mainly to ensure the uniform mixing and full gelatinization of the materials.
Extrusion pressure is generally 2～10MPa. Налягането в екструзионната кухина се определя главно от съотношението на компресия на винта, размера на отвора на матрицата и скоростта на винта. Колкото по-високо е налягането на екструдиране, толкова по-добър е ефектът на издухване, but if the pressure is too high, това ще увеличи консумацията на енергия и износването на оборудването; ако налягането е твърде ниско, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Структура на главата на матрицата:
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
Отдавна се занимаваме с изследването, development and production of food-grade extruders, and have developed a series of twin-screw extruders specially suitable for pet food production according to the characteristics of pet food processing and the needs of enterprises. 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.
Освен това, 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. В същото 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 Широк диапазон на приложение:
Our twin-screw extruders have strong adaptability and can meet the processing needs of various types of pet food, including dry puffed products, полумокри продукти, меки бухнали продукти, 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, барел, 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. например, 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, екструзионно налягане, скорост на винта, material moisture content and production capacity in real time. If any parameter exceeds the set range, системата ще издаде алармен сигнал навреме, and even automatically shut down the equipment if necessary, за избягване на повреда на оборудването и проблеми с качеството на продукта. Освен това, the control system adopts a touch screen operation interface, което е просто и интуитивно, лесен за работа, and can reduce the professional requirements for operators.
3.1.4 Good Product Quality Stability:
Due to the advanced intelligent control system, uniform mixing and full plasticization of materials, the products processed by our extruders have stable quality. The particle size, форма, твърдост, crispness and nutritional composition of the products are uniform, which can meet the strict quality requirements of pet food. В същото време, the extrusion puffing process can effectively kill harmful bacteria in the raw materials (such as Salmonella, Escherichia coli), with a sterilization rate of more than 99%, ensuring the safety of pet food and reducing the risk of pet food safety incidents.
3.1.5 Висока производствена ефективност:
