Twin screw extruder characteristics
Twin screw extruder is a widely used production and processing equipment in the food and feed industries. Its suitable raw materials mainly include powder or grain grains, starch, and some animal fat. According to product requirements, multiple materials can also be mixed for use; This equipment uses twin screw extrusion to process the material under reasonable temperature, pressure, and cutting force, allowing the material to be extruded and shape through a mold. During this process, the material undergoes a series of physical and chemical changes such as expansion, and secondary shaping. Twin screw extruder products are widely used, mainly including casual puffed foods, breakfast cereal, soy protein, artificial rice, pet food, pre gelatinized modified starch, etc. With technological progress, more and more traditional production methods have been replaced by twin screw extrusion technology. Compared to food processing methods such as cooking, baking, and frying, its main advantages are high automation, multi-purpose machine Large single machine output and low energy consumption under the same output.
The twin screw extruder is mainly composed of six parts: extrusion system, electric control system, temperature control system, transmission system, feeding system, and shaping system; It can also be equipped with a vapor conditioning system for wet puffed production as needed. By designing different structures and slenderness ratios according to product needs, screw extrusion systems can meet different process requirements. In actual production, only the production parameters need to be set, and various systems automatically work together, with strong stability and reliable quality.
Mechanical characteristics:
1. The inverter speed control technology adopted by the host makes the equipment powerful, operates more smoothly, and saves electricity;
2. The screw is treated with alloy steel nitriding, resulting in a longer lifespan. Some equipment adopts a modular structure, which can be combined according to different needs;
3. Forced lubrication system to ensure longer service life of the transmission part of the equipment;
4. Visual fully automatic temperature control system to make temperature control more intuitive and parameters more accurate;
5. The screw has self-cleaning function, and there is no need to disassemble the screw for cleaning during shutdown;
6. Different screws and aspect ratios can meet different production processes;
7. The twin screw extruder has a wide range of adaptability to raw materials, multiple product shapes, and flexible configuration;
8. Different models and configurations of puffing food machinery can be selected to produce different products.
