1. Iwwersiicht vun der Pet Food Industrie a Veraarbechtung Charakteristiken
1.1 Aktuell Situatioun an Entwécklung Trend vun der Pet Food Industrie
An de leschte Joren, de weltwäiten Hausdéierfuddermaart huet e stännege Wuesstumstrend gewisen. Ugedriwwe vu Faktoren wéi d'Erhéijung vun der Zuel vun Hausdéieren, d'Aktualiséierung vun Déierekonsumkonzepter, an d'Verbesserung vun den Awunner’ Kafkraaft, der Nofro fir héich-Qualitéit, nährstoffaarme a funktionell Déierefudder ass weider eropgaang. No relevant Daten Statistiken, déi global Déierefuddermaartgréisst ass iwwerschratt 100 Milliarden US Dollar, an et gëtt erwaart engem Wuesstem Taux vun erhalen 5%-8% an den nächste Joren. Ënnert hinnen, dréchen gepafft Déierfudder, als déi meescht Mainstream Produkttyp, Konte fir méi wéi 60% vum Gesamt Déierefuddermaart, gefollegt vun naass Konservenprodukter, semi-naass Produkter an Hausdéieren Snacks.
Den Entwécklungstrend vun der Déierefudderindustrie gëtt haaptsächlech an dräi Aspekter reflektéiert: éischten, Ernährung a Gesondheet. Déierebesëtzer bezuelen ëmmer méi Opmierksamkeet op d'Ernärungskompositioun vun Déierefudder, a Produkter mat natierlechen, additiv-gratis, funktionell (wéi Hoer Schéinheet, Mo Ernährung, Gewiicht Kontroll) Charakteristiken si méi populär; zweeten, Diversifikatioun vun Produktarten. Mat der Beräicherung vun Déiertypen an den individuellen Bedierfnesser vun Déierebesëtzer, Déierefudder huet sech lues a lues a Richtung Segmentatioun entwéckelt, wéi Hausdéierefudder fir verschidden Alter (Welpen, erwuessener Muppen, eeler Hënn), verschidde Rassen, and different physical conditions; drëtten, intelligence and efficiency of processing technology. In order to meet the large-scale production demand and ensure the stability of product quality, pet food processing enterprises are constantly introducing advanced processing equipment and intelligent control systems to improve production efficiency and reduce labor costs.
Virun dësem Hannergrond, extrusion puffing technology, as the core technology of pet food processing (especially dry puffed products), has become the key to determining the quality of pet food and the competitiveness of enterprises. Our professional extruders for pet food production are developed in response to the characteristics of the industry and market demand, déi effektiv d'Schmerzpunkte bei der Déierefudderveraarbechtung léisen an d'Entreprisen hëllefen qualitativ héichwäerteg an effizient Produktioun z'erreechen.
1.2 Klassifikatioun vun Déier Liewensmëttel a seng Veraarbechtung Charakteristiken
Déierefudder huet eng Vielfalt vu Klassifikatiounsmethoden, déi no Veraarbechtungstechnologie a verschiddenen Typen opgedeelt kënne ginn, Waasser Inhalt, Produit Form a Gebrauch. Ënnert hinnen, no der Veraarbechtungstechnologie a Waassergehalt, Déierefudder ass haaptsächlech an dréchen gepaffte Produkter opgedeelt, semi-naass Produkter, mëll puffed Produiten, naass Konserven a Snacks (oder Schneekereien). All Zort vun Déier Liewensmëttel huet seng eege eenzegaarteg Veraarbechtung Charakteristiken an Ufuerderunge fir Ausrüstung, wéi follegt:
1.2.1 Dréchen Puffed Produkter:
Dréchent gepafft Hausdéierfudder ass déi meescht üblech Aart vu Hausdéierefudder, mat engem Waasser Inhalt vun 10%-12%. Seng Haapt Matière première och Fleesch Iessen, Fësch Iessen, Getreide (Mais, Weess, Reis), Sojabohn Iessen, Vitaminnen, Mineralstoffer an aner Zousatzstoffer. De Veraarbechtungsprozess vun dréchene gepaffte Produkter ass enk mam Puffprozess verbonnen, déi d'Benotzung vun Extrusiounsausrüstung erfuerdert fir d'Rohmaterialien a granuläre Produkter mat enger eenheetlecher Gréisst ze veraarbechten, knusprech Geschmaach a gutt Geschmaach. D'Charakteristike vun dréchen gepaffte Produkter si laang Haltbarkeet, praktesch Lagerung an Transport, an niddreg Produktiounskäschte, déi gëeegent sinn fir grouss Produktioun a populär bei Déierebesëtzer.
D'Schlësselveraarbechtungsfuerderung vun dréchen gepaffte Produkter ass datt d'Rohmaterialien komplett gepufft musse ginn, sou datt d'Stärke an de Rohmaterial voll gelatiniséiert ass, wat fir d'Verdauung an d'Absorptioun vun Hausdéieren förderlech ass. Gläichzäiteg, d'Produkt muss eng gewëssen Härtheet a Knuewel hunn fir d'Kaubedierfnesser vun Hausdéieren z'erreechen an hir Zänn ze botzen. Dëst stellt héich Ufuerderungen un den Extrusiounsdrock, Temperatur a Schraufgeschwindegkeet vum Extruder.
1.2.2 Semi-naass Produkter:
Semi-naass Déierefudder huet e Waassergehalt vu 25%-35%, wat tëscht dréchen a naass Produkter ass. Seng Matière première sinn ähnlech ze dréchen puffed Produiten, awer méi humectants (wéi Propylenglycol, sorbitol) ginn bäigefüügt fir d'Weichheet an d'Feuchtigkeit vum Produkt z'erhalen. De Veraarbechtungsprozess vun semi-naass Produkter brauch och Puffbehandlung, awer de Puffgrad ass méi niddereg wéi dee vun dréchene Produkter. D'Produkt huet d'Charakteristike vu mëllen Geschmaach a gudder Geschmaach, déi gëeegent ass fir Hausdéieren mat enger schlechter Kauenfäegkeet (wéi eeler Hausdéieren, krank Hausdéieren).
The processing difficulty of semi-wet products lies in the control of water content and the prevention of product deterioration. Dofir, in the processing process, it is necessary to strictly control the temperature and humidity of each link, and select appropriate preservatives and humectants to ensure the shelf life of the product.
1.2.3 Soft Puffed Products:
Soft puffed pet food has a water content of 15%-25%, which is a product between dry puffed and semi-wet products. Its processing process is similar to that of dry puffed products, but the formula and extrusion parameters are adjusted to make the product soft and elastic. Soft puffed products combine the advantages of dry and semi-wet products, with good palatability and easy digestion, which is suitable for a variety of pets.
1.2.4 Wet Canned Products:
Naass Konserven Déierefudder huet e Waassergehalt vu méi wéi 70%, haaptsächlech frësch Fleesch benotzt, Fësch, Geméis an aner Matière première, déi duerch Kachen veraarbecht ginn, Konserven, Sterilisatioun an aner Prozesser. Verschidde vun aneren Zorte vu Produiten, naass Konservenprodukter brauche keng Puffbehandlung, an hir Kär Veraarbechtung Linken sinn Kachen an Sterilisatioun. D'Produkt huet d'Charakteristike vu räicher Ernährung, staark Geschmaach an héich Feuchtigkeitgehalt, déi gëeegent ass fir Hausdéieren déi net gär Drénkwaasser hunn oder zousätzlech Ernährung brauchen.
De Schlëssel fir d'Veraarbechtung vu naass Konserven ass d'Frëschheet an d'Sécherheet vu Rohmaterial ze garantéieren, a strikt d'Sterilisatiounstemperatur an d'Zäit kontrolléieren fir schiedlech Bakterien am Produkt ëmzebréngen an d'Haltdauer ze verlängeren. Gläichzäiteg, it is necessary to ensure that the nutritional components of the product are not lost during the cooking and sterilization process.
1.2.5 Pet Snacks (or Treats):
Pet snacks are auxiliary food for pets, mainly used to reward pets, improve their mood and supplement nutrition. The types of pet snacks are diverse, including puffed snacks, dried meat snacks, jerky snacks, dental snacks, etc. Ënnert hinnen, puffed snacks account for a large proportion, and their processing process is similar to dry puffed products, but the formula is more refined, and more flavoring agents and functional additives are added to meet the taste and functional needs of pets.
Pet snacks have high requirements for taste, appearance and functionality. Zum Beispill, dental snacks need to have a certain hardness and texture to help clean the pet’s teeth and prevent dental calculus; Hoer-beautifying Snacks mussen Zutaten wéi Lecithin derbäi fir d'Hoerqualitéit vum Hausdéier ze verbesseren. Dëst erfuerdert datt den Extruder gutt Flexibilitéit an Upassbarkeet huet fir d'Veraarbechtungsbedürfnisser vu verschiddenen Aarte vu Snacks z'erreechen.
Et ass derwäert opgeschriwwen dass ausser Konserven Produiten, Déi meescht Aarte vu Hausdéierefudder sinn enk mam Puffprozess verbonnen. Puffing ass net nëmmen de Kär Deel vun der Déierefudderveraarbechtung, awer och direkt d'Qualitéit beaflosst, schmaachen, Ernährung an Verdaubarkeet vun Déierefudder. Dofir, déi richteg Extrusiounsausrüstung auswielen an déi wëssenschaftlech Extrusiounstechnologie beherrschen sinn entscheedend fir Hausdéierveraarbechtungsfirmen.
2. Kär Technologie vun Pet Food Processing: Extrusion Puffing Technology
Extrusion Puffing Technologie ass eng Schlësselveraarbechtungstechnologie déi Mëschung integréiert, kneeden, Heizung, extrusion an puffing. Et gouf wäit an der Produktioun vun Déierefudder benotzt wéinst senge Virdeeler vun héijer Produktiounseffizienz, gutt Produit Qualitéit, staark Upassung un Matière première a breet Applikatioun Gamme. An der Veraarbechtung vun Déierefudder, Extrusiounstechnologie gëtt haaptsächlech benotzt fir d'Puffing vu Matière première ze realiséieren, maachen der Stärke gelatinize, Protein Denaturatioun, a verbessert d'Geschmaach an d'Verdaubarkeet vum Produkt. Gläichzäiteg, et kann och schiedlech Bakterien an de Matière première ëmbréngen, d'Sécherheet vun Déierefudder garantéieren.
2.1 Charakteristiken vun Pet Food Raw Material an Ufuerderunge fir Extrusiounsausrüstung
D'Rohmaterialien vum Hausdéierefudder sinn haaptsächlech Fleeschprodukter (wéi Fleesch Iessen, Fësch Iessen, frësch Fleesch), Getreide, Sojabohn Iessen, Vitaminnen, Mineralstoffer an aner Zousatzstoffer. Ënnert hinnen, Fleeschprodukter maachen e groussen Undeel aus, sou datt de Produit eng staark Viskositéit huet. Dës Charakteristik stellt speziell Ufuerderunge fir Extrusiounsausrüstung vir:
Single-screw extruders sinn net gëeegent fir d'wirtschaftlech Produktioun vun Déier Liewensmëttel. Well de Single-Screw Extruder e schmuele Schéierbereich huet, schlecht Pompelkapazitéit a kee Selbstreinigungseffekt. Beim Veraarbechtung vu viskose Materialien wéi Fleeschprodukter, et ass einfach Materialakkumulatioun ze verursaachen, Blockéierung an ongläiche Vermëschung am Extruderfass, wat net nëmmen d'Produktiounseffizienz beaflosst, mä féiert och zu onbestänneg Produktqualitéit. Zousätzlech, den Een-Schrauwen-Extruder huet en héijen Energieverbrauch beim Veraarbechtung vu Fett- a Protein-Rohmaterial, wat d'Produktiounskäschte vun den Entreprisen erhéicht.
Zwilling-Schrauwen extruders, op der anerer Säit, hunn offensichtlech Virdeeler an der Déierefudderproduktioun. Si hunn e méi breet Schéierbereich, méi effektiv Pompel Effekt an Self-Botzen Effekt, déi d'Problemer vun der Materialviskositéit an der Akkumulation effektiv léise kënnen. D'Zwilling-Screw Extruder kann déi eenheetlech Mëschung realiséieren, Kneaden an Extrusioun vu Materialien, och wann Dir Matière première mat héije Fett a frësch Fleesch Inhalt Veraarbechtung, et kann och eng stabil Produktioun a konsequent Produktqualitéit garantéieren. Dofir, an der eigentlecher Produktioun vun Déierefudder, Zwilling-Schrauwen-Extruder sinn den Haaptmëttel fir Hausdéierefudder ze puffen, a gi wäit an der Produktioun vun dréchen gepaffte Produkter benotzt, semi-naass Produkter, mëll puffed Produkter an Hausdéieren Snacks.
2.2 Aarbechtsprinzip vun der Schraubeextrusioun Puffing
De Schraubeextrusiounspuffprozess vu Hausdéierefudder ass e komplexe kierperlechen a chemesche Prozess, wat d'Interaktioun vu ville Faktoren involvéiert wéi Temperatur, Drock, Schéier Kraaft an Zäit. De spezifeschen Aarbechtsprinzip ass wéi follegt:
Éischten, Matière pretreatment. Déi puderesch Rohmaterialien déi eng gewësse Quantitéit Stärke enthalen (méi wéi 20%) ginn gläichméisseg gemëscht no der Formel, an dann an der tempering Apparat fir tempering Behandlung geschéckt. Den Zweck vun der Tempering ass de Feuchtigkeitgehalt an d'Temperatur vun de Materialien unzepassen, sou datt d'Materialien den idealen Zoustand erreechen ier se an den Extruder erakommen. Allgemeng, de Feuchtigkeitgehalt vun de Materialien nom Tempering gëtt op 10% ~ 27% kontrolléiert, an d'Temperatur gëtt op 70 ~ 98 ℃ erhéicht. Wärend dem Temperéierungsprozess, d'Materialien absorbéieren Waasser gläichméisseg, wat zu der spéider Gelatiniséierung vu Stärke an Denaturatioun vum Protein bäidréit, a kann och d'Verschleiung vun der Extruder Schraube a Faass reduzéieren.
Zweeten, extrusion an Heizung. Déi temperéiert Materialien ginn an d'Schraube-Extrusiounskavitéit duerch d'Fütterungsapparat. D'Schraube-Extrusiounskavitéit besteet aus enger Schraube an engem Faass, an de Volume vun der extrusion Kavitéit lues a lues laanscht d'Achs Richtung erof. Wann d'Schraube dréit, et dréckt d'Materialien kontinuéierlech no vir, an d'Materialien ginn graduell ënner der Handlung vun der Schraube an dem Faass kompriméiert, an den Drock an der Extrusiounskavitéit geet graduell erop. De Kompressiounsverhältnis (de Verhältnis vum Volume vum Material am Fütterend Enn zum Volume um Extrusiounsend) kann 4-10 erreechen, déi variéiert jee no der Aart vun Déierefudder an der Formel vu Rohmaterial.
Während dem Prozess vun der Schraube gedréckt an extrudéiert, d'Materialien ënnerleien staark Schéierkraaft a Reibungskraaft. D'Schéierkraaft gëtt duerch d'relativ Bewegung tëscht der Schraube an dem Faass generéiert, wéi och tëscht de Schrauwen Flich. Et kann d'Partikele vun de Materialien briechen, maachen d'Rohmaterialien an Zousätz méi eenheetlech mëschen, a förderen d'Gelatiniséierung vu Stärke an Denaturatioun vum Protein. The friction force is generated between the materials and the inner wall of the barrel, as well as between the material particles, which can generate a lot of heat, which is conducive to the heating of the materials. Zousätzlech, according to the processing needs, 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.
Drëtten, 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, wat Stäregelatiniséierung genannt gëtt. Stärkegelatiniséierung kann d'Verdaubarkeet vun Déierefudder verbesseren, well de gelatiniséierte Stärke méi einfach duerch d'Verdauungsenzyme vun Hausdéieren ofgebaut gëtt. Gläichzäiteg, déi gelatiniséiert Stärke kann och d'Viskositéit an d'Verbindungskraaft vun de Materialien verbesseren, maachen déi extrudéiert Produkter gutt Form an Textur hunn.
Zousätzlech zu Stärkegelatiniséierung, de Protein an de Materialien wäert och Denaturatioun ënner der Handlung vun héijer Temperatur an héijen Drock ënnergoen. Protein Denaturatioun bezitt sech op d'Verännerung vun der raimlecher Struktur vu Proteinmolekülen ouni d'primär Struktur z'änneren, wat d'Léisbarkeet an d'Verdaubarkeet vum Protein verbesseren kann, a maachen d'Déierfudder besser Geschmaach. Gläichzäiteg, den denaturéierte Protein kann och eng Netzwierkstruktur bilden, déi de Stärke an aner Komponenten wéckele kann, hëlleft fir d'Form vum gepaffte Produkt z'erhalen.
Véierten, puffen a formen. Wann d'Materialien am Héichtemperatur- an Héichdrockzoustand duerch d'Schraube an de Stierkopf gedréckt ginn an aus dem Stierfloch mat héijer Geschwindegkeet extrudéiert ginn, d'Temperatur an den Drock vun de Materialien falen staark, well se op eemol d'Extrusiounskavitéit verloossen an an d'normale atmosphäresch Ëmwelt kommen. Ënnert der kombinéierter Handlung vum Drockdifferenz an Temperaturdifferenz, d'Waasser an de Materialien verdampft séier, de Volume vun de Materialien erweidert séier (der Expansioun Taux kann 2-8 Mol erreechen), an d'Materialien ginn dehydréiert a séier festgestallt fir e porösen ze bilden, knusprech oder mëll puffed Produit.
No extrusion aus dem stierwen Lach, déi gepaffte Materialien ginn duerch de Schneidgerät a kuerze Partikele vun enger eenheetlecher Längt geschnidden (rotativ Messer) am Stierwen Kapp installéiert. D'Längt vun de Partikelen kann ugepasst ginn andeems d'Geschwindegkeet vum Rotary Messer geännert gëtt fir d'Ufuerderunge vu verschiddenen Aarte vu Déierfudder z'erreechen. Zum Beispill, d'Partikele vum Welpenfudder si méi kleng a méi kuerz, während d'Partikele vum erwuessene Hondsfudder méi grouss a méi laang sinn.
Fënneften, Postveraarbechtung. Déi extrudéiert gepaffte Partikelen mussen duerch Postveraarbechtungslinks goen wéi d'Trocknung, ofkillen, Gewierz a Verpackung fir déi lescht Hausdéierprodukter ze ginn. D'Trocknung ass fir de Waassergehalt vun de Partikelen op d'Standardberäich ze reduzéieren (10%-12% fir dréchen Produkter), fir d'Haltdauer vum Produkt ze verlängeren. Ofkillung ass d'Temperatur vun de gedréchent Partikelen op Raumtemperatur ze reduzéieren, verhënneren datt d'Produkt kachen a verschlechtert. D'Gewierzung ass fir Aromastoffer ze sprëtzen, Attraktivitéiten an aner Zousatzstoffer op der Uewerfläch vun de Partikelen fir d'Geschmaach vum Produkt ze verbesseren. Verpackung ass d'erwaart Partikelen a Poschen oder Dosen ze packen fir d'Hygiène a Sécherheet vum Produkt ze garantéieren an d'Lagerung an den Transport ze erliichteren.
2.3 Schlëssel Facteuren Afloss Screw Extrusion Puffing Effekt
Den Effet vum Schraube-Extrusiounspuffing beaflosst direkt d'Qualitéit vum Déierefudder. Et gi vill Faktoren, déi de Puffeffekt beaflossen, haaptsächlech mat Matière première Charakteristiken, Tempering Parameteren, extrusion Parameteren an stierwen Kapp Struktur. Dës Schlësselfaktoren beherrschen a wëssenschaftlech Upassunge maachen kënnen d'Stabilitéit vum Puffing Effekt an d'Konsistenz vun der Produktqualitéit garantéieren.
2.3.1 Matière première Charakteristiken:
Den Typ, Partikelgréisst, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Zum Beispill, 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, allgemeng 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%. Wann de Feuchtigkeitgehalt ze héich ass, 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 Minutten, 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. Zum Beispill, 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, haaptsächlech dorënner Schrauwen Vitesse, extrusion Temperatur an extrusion Drock. Screw speed generally ranges from 100 zu 600 rpm. Wat méi héich ass d'Schraubegeschwindegkeet, wat méi grouss d'Schéierkraaft an d'Reibungskraaft vun de Materialien kritt, the higher the extrusion temperature and pressure, and the better the puffing effect. Allerdéngs, wann d'Schraubegeschwindegkeet ze héich ass, d'Residenzzäit vun de Materialien an der Extrusiounshöhle ass ze kuerz, resulting in incomplete starch gelatinization and uneven mixing; wann d'Schraubegeschwindegkeet ze niddreg ass, d'Schéierkraaft an d'Reibungskraaft sinn net genuch, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: fidderen Rubrik, melting section and homogenizing section. The temperature of the feeding section is lower (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. 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.
