Decryption of Large Twin-Screw Extruder

1.Principle and working process

The large twin-screw extruder is an important piece of equipment in the food processing industry and plays an indispensable role in the food production process. This article will reveal the principles, applications and advantages of large-scale twin-screw extruders, and let us explore this eye-catching industrial device together.

2. Extruder

The large twin-screw extruder uses advanced extrusion technology to process ingredients under high temperature and high pressure. It is mainly composed of two rotating screws. Through appropriate parameter settings, it can realize the processes of puffing, gelatinizing and baking of ingredients.

During the working process, after the food enters the machine, it first passes through the preheating section, where the temperature is raised to soften the food; then it enters the puffing section, where due to the high-speed rotation of the screw and the high-pressure environment, the food expands rapidly to form a porous structure; finally, after passing through the cooling section, the food Curing, lowering the temperature, and shaping and cutting to finally get the desired product.

3.Application areas

Large twin-screw extruders are widely used in the food processing industry, especially in the production of cereal products and snack foods. It is often used to produce breakfast cereals, puffed rice cakes, puffed bean products, puffed snacks, etc.

This kind of machine can not only process traditional ingredients, but also handle various ingredients and seasonings, enabling diversified product development. Its processing process is highly controllable and can meet the quality and taste requirements of different products.

4.Advantages and Value

Efficient production: The twin-screw structure makes the processing efficiency higher, which can greatly improve the production efficiency and meet the needs of large-scale production.

Multi-function operation: By adjusting parameters such as screw speed, pressure and temperature, you can process and bake different ingredients to adapt to diverse product needs.

Controllable product quality: The precise and stable control system ensures the quality and taste of the product during the puffing process, providing a better consumer experience.

Energy saving and environmental protection: Using advanced heating and cooling technology, it can accurately control energy consumption and reduce the generation of waste materials and emissions, in line with the requirements of sustainable development.

Large twin-screw extruders are increasingly used in the food processing industry, bringing huge economic benefits and market competitiveness to enterprises. It not only meets modern people's needs for high-quality and diversified food, but also promotes technological innovation and development in the food industry.
