What is the principle of making puffed food

Puffing, a processing method. Make the raw materials suddenly depressurize and expand under heating and pressure. The process of rapidly expanding starch containing materials by suddenly removing external forces and heat sources after heating and pressurization.

The puffed foods sold on the market, such as potato chips, shrimp strips, popcorn, etc., give people the impression of "four highs and one more", high in fat, high in calories, high in salt, high in sugar, and high in monosodium glutamate. Therefore, in the eyes of many people, puffed foods are considered junk food, leading them to believe that anything made with puffed technology is not healthy food. However, this is not the case.

Let's take a look at these so-called "puffed foods", such as potato chips and shrimp chips. In order to cater to the taste of most people, many flavoring agents, such as essence and monosodium glutamate, have been added to these food ingredients to make these foods taste good and full of flavor. The more you eat, the more you want to eat them.

As a result, people's appetite for meals decreases, and some simply skip meals, which directly affects the normal intake of nutrients in the body and leads to malnutrition. These phenomena are not caused by puffed processed foods, but by additives.

This machine is in its original state for puffing technology. When I was a child, I used to use rice for processing. As it was about to ripen, I saw the old man with a face full of black and gray use a metal stick to pry open the machine mouth. With a loud bang, the fragrance of rice flowers wafted through the thick white smoke, making me feel incredibly happy.

The modern puffing process is similar to the popcorn machine of the past, with the same principle.

The twin-screw extruder produced by Jinan Huaxin Shengda Machinery Technology Co., Ltd. consists of several parts, including feeding system, extrusion system, heating system, transmission system, rotary cutting system, and control system. Feed the material into the feeder, and the barrel undergoes high temperature, high pressure, and high shear to expand the material and achieve the required quality requirements such as tissue state.

Puffed foods are made from grains, beans, potatoes, vegetables, and other raw materials. Through the processing of puffed food machinery and equipment, a wide variety of exquisite, nutritious, crispy, and delicious foods are produced. Therefore, a large category of food has been formed. Moreover, the equipment for producing this puffed food has a simple structure, easy operation, low equipment investment, and fast returns. Has good development prospects.
