In food extrusion processing, a machine called an extruder is used to squeeze and push out raw food materials, which changes their shape and structure. During this process, the food materials are put under high pressure and shear forces, which change their internal structure and make the finished products have different textures and shapes.
Using low-temperature processing techniques helps keep the food's nutritional value and taste. Food extrusion processing can also make many different kinds of food, like biscuits, candy, potato chips, meat products, and so on. Also, this method of processing is very efficient, uses little energy, and isn't too expensive. This makes it easy to automate by using production lines.
Food extrusion processing can be used on wheat, rice, beans, meat, and other food raw materials. Different types of extruders can be used to make different products. For example, the horizontal extruder is used to make biscuits and bread, the vertical extruder is used to make candy and nougat, and the extrusion extruder is used to make tofu, meatballs, and fish balls.
Overall, food extrusion processing technology is an important and flexible way to make food. Its benefits include:
Keeping nutrients and taste.
Making a wide range of products.
Being very efficient and cost-effective.
As technology advances, its application scope continues to expand.
