Food Extruder

This food extruder is a type of equipment used in food production processing. It primarily utilizes a process involving high temperature, high pressure, and sudden release to rapidly puff (expand in volume) the raw materials, thereby altering the physical properties and texture of the food. In this process, the moisture within the raw materials evaporates, resulting in volumetric expansion and the formation of a porous structure. This machine is commonly employed in the production of various puffed foods, such as puffed grains, puffed corn flakes, and puffed pasta. It plays a crucial role in the food industry, not only enhancing the texture of products but also improving the nutritional absorption of the food.
Puffing Process:
1. Heating: The raw materials are heated to high temperatures, typically using methods such as steam or electric heating.
2. High Pressure: Simultaneously with heating, high pressure is applied through screws to subject the material to high-temperature and high-pressure conditions.
3. Sudden Release: At a specific moment, the material experiencing high temperature and pressure is rapidly released into an environment with lower pressure.
4. Puffing:The rapid release causes moisture to evaporate, leading to the puffing effect where the material expands in volume, forming the puffed product.

1. The series of extrusion puffing machines are mainly composed of a feeding system, extrusion system, cutting system, heating system, lubrication system, and control system.
2.The feeding system, main drive system, and cutting system of the extruder adopt variable frequency speed control, providing strong power, smooth operation and low energy consumption.
3.Automatic lubrication and forced cooling ensure the safe operation and extended lifespan of the extruder.
4.The screws are made of alloy materials and undergo special processing, resulting in high strength, wear resistance, and a long service life.
5.Different screw extrusion systems with varied structures and length-to-diameter ratios are available to meet the process requirements for different products.

The food puffing machine has a wide range of adaptability to different raw materials and flexible configurations. Various models and setups can be utilized to produce different products. It can be employed to manufacture a variety of items including snacks, dog food, fish feed, corn flakes, rice, nutritional powder, textured vegetable protein, soy products, crispy rice cakes, french fries, potato chips, crispy rice, filled rice dumplings, golden corners, modified starch, instant noodles, and more.
