2.2 Prinsipio di Trabou di Puffing di Ekstrushon di Skruf
E proseso di ekstrushon di skru di kuminda di bestia di kas ta un proseso físiko i kímiko kompleho, ku ta enserá e interakshon di múltiple faktor manera temperatura, preshon, forsa di kòrtamentu i tempu. E prinsipio di trabou spesífiko ta lo siguiente:
Prome, pretratamentu di materia prima. E materia prima polvo ku ta kontené un sierto kantidat di zeta (mas ku 20%) ta wòrdu mesklá uniformemente segun e fórmula, i despues manda pa e aparato di temperamentu pa tratamentu di temperamentu. E propósito di temperamentu ta pa ahusta e kontenido di humedat i temperatura di e materialnan, di manera ku e materialnan por yega na e estado ideal promé ku drenta e ekstruder. Generalmente, e kontenido di humedat di e materialnan despues di temperamentu ta wòrdu kontrolá na 10%～27%, i e temperatura ta wòrdu hisa te na 70～98°C. Durante e proseso di temperamentu, e materialnan ta apsorbé awa uniformemente, 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.
Segundo, 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, and the pressure in the extrusion cavity gradually increases. The compression ratio (the ratio of the volume of the material at the feeding end to the volume at the extrusion end) can reach 4～10, ku ta varia segun e tipo di kuminda pa bestia di kas i e fórmula di materia prima.
Durante e proseso di wòrdu pushá i ekstruí dor di e skru, e materialnan ta wòrdu sometí na forsa di kòrtamentu fuerte i forsa di frikshon. E forsa di kòrtamentu ta wòrdu generá dor di e moveshon relativo entre e skru i e bari, meskos ku entre e buelonan di skru. E por kibra e partikulonan di e materialnan, hasi e materia prima i aditivonan meskla mas uniformemente, i promové e gelatinisashon di zeta i desnaturashon di proteina. E forsa di frikshon ta wòrdu generá entre e materialnan i e muraya paden di e bari, meskos ku entre e partikulonan di material, ku por generá hopi kalor, ku ta kondusivo na e keintamentu di e materialnan. Ademas, segun e nesesidatnan di prosesamentu, vapor por flui dor di e djaka di bari pa keinta e materialnan entre e murayanan, di manera ku e materialnan den e kavidat di ekstrushon ta den un estado di temperatura haltu i preshon haltu. E temperatura den e kavidat di ekstrushon ta wòrdu kontrolá generalmente na 120～180°C, i e preshon ta wòrdu kontrolá na 2～10MPa.
Di tres, gelatinisashon di zeta i desnaturashon di proteina. Bou di akshon di temperatura haltu, preshon haltu i forsa di kòrtamentu, e zeta den e materialnan ta apsorbé awa i ta ekspandé, e struktura di kristal ta destruí, i e ta wòrdu kombertí den un estado amorfo, ku ta wòrdu yamá gelatinisashon di zeta. Gelatinisashon di zeta por mehorá e digestibilidat di kuminda di bestia di kas, pasobra e zeta gelatinisá ta mas fásil pa wòrdu deskomponé dor di e enzimanan digestivo di bestianan di kas. Na mes momento, e zeta gelatinisá tambe por mehorá e viskosidat i forsa di uni di e materialnan, hasiendo e produktonan ekstruí tin bon forma i tekstura.
Ademas di gelatinisashon di zeta, e proteina den e materialnan tambe lo pasa den desnaturashon bou di akshon di temperatura haltu i preshon haltu. Desnaturashon di proteina ta referí na e kambio di e struktura espasial di molèkülnan di proteina sin kambia e struktura primario, ku por mehorá e solubilidat i digestibilidat di proteina, i hasi e kuminda di bestia di kas tin mihó sabor. Na mes momento, e proteina desnaturá tambe por forma un struktura di ret, ku por envolví e zeta i otro komponentenan, yudando pa mantené e forma di e produkto hinchá.
Di kuater, hincha i forma. 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. Por ehèmpel, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Di sinku, post-processing. The extruded puffed particles need to go through post-processing links such as drying, friamentu, 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, prevent the product from caking and deteriorating. Seasoning is to spray flavoring agents, atrayentenan i otro aditivonan riba e superfisie di e partikulonan pa mehorá e sabor di e produkto. Empaketamentu ta pa paketá e partikulonan sasoná den saku òf bleki pa garantisá e higiena i seguridat di e produkto i fasilitá almasenamentu i transporte.

2.3.1 Karakterístika di Materia Prima:
E tipo, tamaño di partikulo, kontenido di humedat i komposishon nutrishonal di materia prima tin un impakto grandi riba e efekto di hinchamentu. Por ehèmpel, e kontenido di zeta di materia prima ta afektá direktamente e tasa di ekspanshon di e produkto. Mas haltu e kontenido di zeta ta (denter di un sierto rango), mas mihó e efekto di bula, i mas grandi e tasa di ekspanshon di e produkto. E tamaño di partikulo di materia prima mester ta uniforme, generalmente 80-100 mesh. Si e tamaño di partikulo ta muchu grandi, e materialnan no ta fásil pa wòrdu mesklá uniformemente i plastifiká kompletamente, ku ta afektá e efekto di hinchamentu; si e tamaño di partikulo ta muchu chikitu, ta fásil pa kousa blokeo di material i oumentá konsumo di energia. E kontenido di humedat di materia prima promé ku temperá mester ta kontrolá na 8%-12%. Si e kontenido di humedat ta muchu haltu, e materialnan ta fásil pa pega na e skru i bari, afektando e ekstrushon i hinchamentu; si e kontenido di humedat ta muchu abou, e forsa di kòrtamentu i forsa di frikshon entre e materialnan ta insufisiente, i e gelatinisashon di zeta ta inkompleto, resultando den mal efekto di bula.
2.3.2 Parameternan di Temperashon:
Parameternan di temperamentu ta inkluí prinsipalmente temperatura di temperamentu, tempu di temperá i kontenido di humedat despues di temperá. E temperatura di temperamentu ta generalmente 70～98°C. Si e temperatura di temperamentu ta muchu abou, e materialnan no por apsorbé awa uniformemente, i e gelatinisashon di zeta ta insufisiente; si e temperatura di temperamentu ta muchu haltu, e materialnan por wòrdu trahá di antemano, afektando e ekstrushon siguiente. E tempu di temperamentu ta generalmente 2-5 minütnan, ku mester wòrdu ahusta segun e tipo di materia prima i e kontenido di humedat. E kontenido di humedat despues di temperamentu ta 10%～27%, ku ta varia segun e tipo di kuminda pa bestia di kas. Por ehèmpel, e kontenido di humedat di produktonan seku despues di temperamentu ta generalmente 15%-20%, miéntras ku esun di produktonan semi-muhá ta 22%-27%.
2.3.3 Parameternan di Ekstrushon:
Parameternan di ekstrushon ta e faktornan mas importante ku ta afektá e efekto di hinchamentu, prinsipalmente inkluyendo velosidat di skru, temperatura di ekstrushon i preshon di ekstrushon. Velosidat di skru generalmente ta varia di 100 pa 600 rpm. Mas haltu e velosidat di e skru, mas grandi e forsa di kòrtamentu i forsa di frikshon risibí pa e materialnan, mas haltu e temperatura i preshon di ekstrushon ta, i mas mihó e efekto di bula. Pero, si e velosidat di skru ta muchu haltu, e tempu di estadia di e materialnan den e kavidat di ekstrushon ta muchu kòrtiku, resultando den gelatinisashon di zeta inkompleto i meskla desigual; si e velosidat di skru ta muchu abou, e forsa di kòrtamentu i forsa di frikshon ta insufisiente, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: sekshon di alimentashon, 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, mas mihó e efekto di bula, 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, i mas mihó e efekto di bula, 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.
