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.
