Zhuoyue provides the extruder special for food production

food production and processing process

Pet food processing technology is a combination of the feed production process and food production process. The types of pet food are dry puffed products, semi-wet products, soft puffed products, wet canned products, and snacks (or treats). In addition to canned products, most types of pet food are closely related to the puffing process. This shows that puffing is the core part of the pet food processing industry. And in the processing of pet food is the use of extrusion technology.

Pet food raw materials are mainly meat products, the product is sticky, and can not use a single-screw extruder for economic production. The twin-screw extruder reduces the shear range, has a more effective pumping action and self-cleaning effect, suitable for the production of fresh meat and feed containing high fat. Therefore, in the actual production of pet food, the use of a twin-screw extrusion puffing machine is.

The working principle of the screw extrusion puffing machine : 

to contain a certain amount of starch (more than 20%) of the powdered raw materials, tempered by the tempering device tempering treatment, so that the material moisture to 10% ~ 27%, the temperature rises to 70 ~ 98 ℃. The tempered material into the screw extrusion cavity, as the volume of the extrusion cavity along the axis gradually becomes smaller, the pressure on the material gradually increased, and the compression ratio of up to 4 ~ 10. Material is pushed by the screw extrusion, accompanied by strong shear and friction, according to the need can also be through the barrel jacket steam flowing through the inter-wall heating of the material, so that the material is in a high temperature, high-pressure state, the material in the starch paste. The starch in the material is pasteurized. When the material is extruded from the die hole with great pressure, due to the sudden departure of the body into the atmosphere, the temperature and pressure plummet, under the joint action of the pressure difference, and temperature difference, the feed volume rapidly expands, rapid evaporation of water, dehydration, and solidification, and then cut by the knife into short particles, the formation of puffed granular feed.

The Key benefits of zhuoyue extruder

Low-cost lifetime operation

The interior of the barrel is extremely resistant to wear, extending its operating lifetime. Our barrel wear measurement service can detect wear and tear in good time, ensuring you only replace parts when needed.

Wide range of applications

The high torque, variable screw speeds, and pressure variables on our twin-screw extruders offer you excellent flexibility to meet different process requirements. Modular design allows you to customize each machine for your application.

State-of-the-art technology for reliable process control

An intelligent recipe memory helps you to deliver consistent end-product quality every time. It also helps you to minimize process and operator errors and makes it faster to switch between different recipes.

Specification of twin screw extruder ( The HTS models )

The HTS BASIC range uses medium torque transmissions from leading European manufacturers and offers the flexibility of choice through different configuration combinations.
