Aynı zamanda, aynı zamanda ham maddelerdeki zararlı bakterileri de öldürebilir, evcil hayvan mamasının güvenliğini sağlamak.
2.1 Evcil Hayvan Yemi Hammaddelerinin Özellikleri ve Ekstrüzyon Ekipmanı Gereksinimleri
Evcil hayvan mamasının hammaddeleri çoğunlukla et ürünleridir (et yemeği gibi, balık unu, taze et), mısır gevreği, soya küspesi, vitaminler, mineraller ve diğer katkı maddeleri. Aralarında, Et ürünleri büyük bir paya sahip, Ürünün güçlü viskoziteye sahip olmasını sağlamak. Bu özellik, ekstrüzyon ekipmanı için özel gereksinimleri ortaya koymaktadır:
Tek vidalı ekstruderler evcil hayvan gıdalarının ekonomik üretimi için uygun değildir. Çünkü tek vidalı ekstruderin kesme aralığı dardır, zayıf pompalama kapasitesi ve kendi kendini temizleme etkisi yok. Et ürünleri gibi viskoz malzemeleri işlerken, malzeme birikimine neden olmak kolaydır, ekstruder tamburunda tıkanma ve eşit olmayan karıştırma, bu sadece üretim verimliliğini etkilemekle kalmıyor, ama aynı zamanda dengesiz ürün kalitesine de yol açar. Ek olarak, tek vidalı ekstruder, yüksek yağlı ve yüksek proteinli hammaddeleri işlerken yüksek enerji tüketimine sahiptir, işletmelerin üretim maliyetini artıran.

2.2 Vidalı Ekstrüzyon Şişirmenin Çalışma Prensibi
Evcil hayvan mamasının vidalı ekstrüzyon şişirme işlemi karmaşık bir fiziksel ve kimyasal işlemdir, sıcaklık gibi birden fazla faktörün etkileşimini içeren, basınç, kesme kuvveti ve zamanı. Spesifik çalışma prensibi aşağıdaki gibidir:
Birinci, hammadde ön işlemi. Belirli miktarda nişasta içeren toz halindeki hammaddeler (bundan fazla 20%) formüle göre eşit şekilde karıştırılır, ve daha sonra temperleme işlemi için temperleme cihazına gönderilir. Temperlemenin amacı malzemelerin nem içeriğini ve sıcaklığını ayarlamaktır., böylece malzemeler ekstrudere girmeden önce ideal duruma ulaşabilir. Genel olarak, temperleme sonrasında malzemelerin nem içeriği ~' arasında kontrol edilir, ve sıcaklık 70~98°C'ye yükseltilir. Temperleme işlemi sırasında, malzemeler suyu eşit şekilde emer, bu, nişastanın daha sonra jelatinleşmesine ve proteinin denatürasyonuna yardımcı olur, ve ayrıca ekstruder vidasının ve kovanının aşınmasını da azaltabilir.
Saniye, ekstrüzyon ve ısıtma. Temperlenmiş malzemeler besleme cihazından vidalı ekstrüzyon boşluğuna girer. The screw extrusion cavity is composed of a screw and a barrel, ve ekstrüzyon boşluğunun hacmi eksen yönü boyunca kademeli olarak azalır. 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, ve ekstrüzyon boşluğundaki basınç giderek artar. 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, which varies according to the type of pet food and the formula of raw materials.
During the process of being pushed and extruded by the screw, the materials are subjected to strong shear force and friction force. The shear force is generated by the relative movement between the screw and the barrel, vida uçuşları arasında olduğu gibi. It can break the particles of the materials, make the raw materials and additives mix more uniformly, ve nişastanın jelatinizasyonunu ve proteinin denatürasyonunu teşvik eder. Sürtünme kuvveti, malzemeler ile namlunun iç duvarı arasında üretilir., ve ayrıca malzeme parçacıkları arasında, çok fazla ısı üretebilen, Malzemelerin ısıtılmasına elverişli olan. Ek olarak, işleme ihtiyaçlarına göre, buhar, duvarlar arasındaki malzemeleri ısıtmak için namlu ceketinden akabilir, böylece ekstrüzyon boşluğundaki malzemeler yüksek sıcaklık ve yüksek basınç durumundadır. Ekstrüzyon boşluğundaki sıcaklık genellikle 120~180°C'de kontrol edilir, ve basınç 2~10MPa'da kontrol edilir.
Üçüncü, nişasta jelatinizasyonu ve protein denatürasyonu. Yüksek sıcaklığın etkisi altında, yüksek basınç ve kesme kuvveti, malzemelerdeki nişasta suyu emer ve genişler, 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. Aynı zamanda, the gelatinized starch can also improve the viscosity and binding force of the materials, making the extruded products have good shape and texture.
In addition to starch gelatinization, the protein in the materials will also undergo denaturation under the action of high temperature and high pressure. Protein denaturation refers to the change of the spatial structure of protein molecules without changing the primary structure, which can improve the solubility and digestibility of protein, and make the pet food have better palatability. Aynı zamanda, the denatured protein can also form a network structure, which can wrap the starch and other components, helping to maintain the shape of the puffed product.
Dördüncü, 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. Örneğin, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Beşinci, post-processing. The extruded puffed particles need to go through post-processing links such as drying, soğutma, 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, 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, mainly including raw material characteristics, tempering parameters, extrusion parameters and die head structure. 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 Raw Material Characteristics:
The type, parçacık boyutu, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Örneğin, 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 örgü. 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%. Nem içeriği çok yüksekse, 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 dakika, 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. Örneğin, 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 ile 600 devir/dakika. 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. Fakat, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete starch gelatinization and uneven mixing; if the screw speed is too low, the shear force and friction force are insufficient, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: feeding section, 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. Ekstrüzyon boşluğundaki basınç esas olarak vidanın sıkıştırma oranıyla belirlenir., kalıp deliği boyutu ve vida hızı. Ekstrüzyon basıncı ne kadar yüksek olursa, 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.
