The pet feed production line is divided into two processes, dry production and wet production. The company has developed various pet food production lines. Depending on the output, the production line also has multiple configurations to meet different customers. This is a big problem. Through the adjustment of raw materials, temperature, moisture and other process parameters, the product has the characteristics of novel shape, unique taste, rich nutrition, fine organization, etc., and is suitable for different pet tastes. With the increase of pet types, there are adults and young people in all kinds of pets, and the demand for pet food is also increasing. Production equipment and production lines are widely used in the production of dog, cat, fish, shrimp, fox, monkey and various pet feeds. This is an ideal choice for different manufacturers.
raw material: Corn, flour, rice, meat (meat meal), bone meal, fruits and vegetables, etc.
product: Dog food, cat food, fish feed, etc.
Custom shapes according to mold, circle, bone, triangle, heart, circle, etc.
Production Process: Material mixing --extrusion---baking---spray seasoning---cooling packaging
Dog food machine Configuration: Powder mixing → screw conveyer→ twin screw food extruder → Hoister → continuous oven → drum line → cooler → packing machine
Processing steps of pet food production line
1. Raw material reception and cleaning
Prepare all raw materials for making pet food and clean them.
It guarantees all materials are crushed into required size or powder.
Mixing process is a key process in pet food production. The basic process is to weigh the raw materials in different weight according to fomula, then pour them in the crusher to decrease size, and later all materials are temporarily stored in the storage silo. Then all matrials are ready, feed them in the mixer for mixing.
4. Pet food extruding
Extruding is a heat treatment process with high temperature and in short time. It can not only reduce the degradation of food nutrients, improve the digestibility of protein starch, but also destroy the anti nutrient components and microorganism. All shapes of pet dry food such as round, triangle, flower shape and bone shape can be produced through different molds (templates) of the feed extruder machine. In pet food production, fat is usually added to improve pet food palatability, and this is carried out in conditioning process. Besides, to give different colors to pet food tablets, manufacturers usually add pigmented water in extruding chamber.
The drying section is mainly used for removing water in the extruded pet food. After extrusion, the texture of the material is relatively soft and water content reaches 20~30%. After the drying process, the finished product moisture is controlled at 8%~10%, which can ensure that the material is stored in a certain period of time.
6. Oil and fat spraying
Oil and fat are the best source of energy, so 2%~40% of oil and fat can be added to formula according to pet growth needs. We suggest that the content of the fat in the formula, that is the content of the total oil in the extruder be kept within 12%. If the content of the oil is required over 12% and the firmness of the granular material will be significantly reduced. If the extruded material needs more than 12% oil content, the extra oil is suggested to be added in the way of external spray after drying. It can be used at normal pressure or vacuum spray depending on how much oil is added. The external spraying will make the pet food tablets appearance more tempting. In addition to oil, some powdered attractant is also sprayed to increase pet feed palatability.
7. Cooling & sieving
The main purpose of the cooling section is to cool the dried material from high temperature to near room temperature and take away part of the moisture content. Also, in this process, the ineligible food tamblets will be separate from eligible ones.
8. Pet food packaging
Some manufacturers package the pet food of same shapes in one bag, but some would blend several pet food tamblets in different shapes and colors together and pack them in one bag. The conventional weight include: 5kg, 1kg, 500g, 20g, and also 20-50kg large package.
