The extruder integrates multiple functions such as compression, mixing, kneading, shearing, melting, sterilization, puffing, and molding, and completes them all in a very short time. The shape and size of the product can be infinitely changed by the change of the mold, and the twin-screw extruder The machine can produce a wide variety of foods, such as casual snacks, breakfast cereals, puffed sandwiches, instant rice noodles, soup, bread slices, textured vegetable protein, candy, seasoning components, pet food, fish and shrimp feed, etc. And can develop countless new types of food.

Throughout the development needs of the industry, food puffing machinery can be considered from the following four aspects:

1. Scale applicability. The equipment used by my country's puffed food processing enterprises is mainly divided into three types: large, medium and small.

2. Safety applicability. Safety applicability refers to mechanical safety, production safety and food safety in puffed food processing.

3. Applicability of complete sets. Applicability of complete sets is an important link to ensure continuous operation, balanced production, processing performance and product quality.

4. Hygienic applicability. It is a healthy requirement for the mechanical structure of the puffed food machinery design and manufacturing process.


It mainly includes hygienic requirements such as structural materials, surface structure, cleanability, durability, and inspectability of product contact surfaces and non-product contact surfaces:

  Main features of food puffing machinery: Food puffing machinery is the most popular main engine in the market now, and its production of puffed food (pet food, fish feed, etc.) has a wide range of applications. Among them, 70 are screw

Outer diameter diameter size The machine is composed of a feeding system, an extrusion system, a rotary cutting system, a heating system, a transmission system, and a control system. It adopts advanced screw extrusion technology and utilizes high temperature and high pressure

The material is matured and extruded into shape, which is completed at one time. The main machine adopts frequency conversion speed regulation to ensure the stability of the production process. The product has a variety of colors and varieties, beautiful appearance, natural and realistic, delicate texture, and a wide range of raw materials.
