Pet Food Processing Line

Description

Pet food processing refers to the use of various necessary methods to enable dogs, cats and other pets to obtain the maximum potential nutritional value of food. In fact, it refers to changing the raw material composition, shape, palatability and other characteristics of pet food in a certain way to make pets Maximize the value of its feed pellets. In order to ensure the full and safe use of food nutrition during the pet food manufacturing process, the raw materials used must be processed to varying degrees.

The capacity: 100kg/h --- 500kg/h. 

Products: Pet food, aquatic feed, bird food, ect.

There are three drying methods about dryer, gas, electricity, steam. 

Pet food Production line of work flow:

Now, the establishment of pet food processing plants that produce high-quality pet feed pellets has become a popular project. Therefore, developing a pet food production business is an excellent choice for many investors to obtain long-term profits.

Pet food manufacture process

Pet food processing refers to the use of various necessary methods to enable dogs, cats and other pets to obtain the maximum potential nutritional value of food. In fact, it refers to changing the raw material composition, shape, palatability and other characteristics of pet food in a certain way to make pets Maximize the value of its feed pellets. In order to ensure the full and safe use of food nutrition during the pet food manufacturing process, the raw materials used must be processed to varying degrees.

• Raw material reception and cleaning process

Prepare all raw materials for making pet food and clean them.

• Crushing process

It guarantees all materials are crushed into required size or powder.

• Mixing process

Mixing process is a key process in pet food production. The basic process is to weigh the raw materials in different weights according to formula, then pour them in the crusher to decrease size, and later all materials are temporarily stored in the storage silo. Then all materials are ready, feed them in the mixer for mixing.

• Pet food extruding process

Extruding is a heat treatment process with high temperature and in a 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 the conditioning process. Besides, to give different colors to pet food tablets, manufacturers usually add pigmented water in the extruding chamber.

• Drying process

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.

• Oil and fat spraying process

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.

• Cooling & sieving process

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 tablets will be separate from eligible ones.

• Pet food packaging process

Some manufacturers package the pet food of the same shapes in one bag, but some would blend several pet food tablets in different shapes and colors together and pack them in one bag. The conventional weight includes: 5kg, 1kg, 500g, 20g, and also 20-50kg large packages.
