Characteristics of twin-screw extruder

Puffed food is made from grains, beans, potatoes, etc. It is processed using puffed food equipment, featuring a fine appearance, rich nutrition, crispy texture, and diverse product varieties. Puffed food, also known abroad as extruded food, popped food, or lightweight food, is a new type of food that has developed internationally in recent years. Because the equipment for producing this puffed food has a simple structure, easy operation, low equipment investment, and quick returns, it has developed rapidly and shown great vitality.

Types of puffed food equipment

Due to different uses and equipment, puffed food machinery has the following three types:

First, using an extrusion puffing machine to produce small foods from corn and potatoes; second, using an extrusion puffing machine to produce structured protein foods (plant-based meat) from plant protein; third, using grains, beans, or potatoes as raw materials, which are puffed to make staple foods. In addition to the trial production of indirect heating puffing machines, refined grain puffing powder has also been used to trial-produce a variety of puffing technology foods.

Main features of puffed food equipment:

1. The main machine adopts frequency converter speed regulation technology, making the equipment more powerful, smoother in operation, and more energy-efficient.

2. The screw is made of alloy steel and treated with nitriding, resulting in a longer service life. Some equipment mainly adopts a modular assembly structure, allowing arbitrary combinations based on different production needs. 3.3 A forced lubrication system ensures a longer lifespan for the transmission parts of the equipment. 4.4 A visible fully automatic temperature control system makes temperature control more intuitive and parameters more accurate for puffed food equipment. 5.5 The screw has a self-cleaning function, eliminating the need to disassemble and clean it when stopping the machine.

6. Different screws and length-to-diameter ratios can meet various production processes.

7. High food puffing rate. 7. The twin-screw extruder has a wide range of raw material adaptability, diverse product shapes, and flexible configurations. Different models and configurations can produce different products.

The above is an introduction to the characteristics of puffed food equipment. Did you get it?
