Food extruders and rice crust

Food extruder is currently widely used in the production of rice crust. Under the conditions of high temperature, high pressure and high shear force, the physical properties of the material change, forming a loose, porous and crisp structure, so as to achieve the purpose of puffing.

At present, the extrusion and puffing equipment on the market includes single-screw extruder, twin-screw extruder and multi-screw extruder, among which twin-screw extruder has a better effect in the production of rice cakes. It is understood that the current twin-screw extrusion equipment is developing in the direction of high torque, high speed and low energy consumption. In the future, the production efficiency will be further improved, and the output and quality will be effectively enhanced.

In addition to extrusion puffing, some new puffing technologies have also been applied in the food industry, and microwave puffing is one of them. Microwave is to use electromagnetic waves to heat the inside and outside of the material at the same time, so that the starch, protein, etc. inside the material are denatured to achieve the purpose of puffing. Due to the high energy conversion rate and rapid heating, the production speed of microwave puffing is very fast. And the microwave heats the inside and outside of the material together, and the puffing effect is very uniform.

In recent years, the application prospect of microwave puffing in the food industry has become more and more extensive. Microwave puffing is used in the production of rice products, soy products, pigskin, fish maw, fish skin, potato chips, potato chips, shrimp chips and other products. equipment. As a new direction for the development of puffing technology, microwave puffing technology is becoming more and more mature, and the cost of equipment is also decreasing.
