Feed expander is an important equipment for modern livestock feed processing. It can process raw materials under high temperature and pressure, so that the feed can obtain multiple advantages such as expansion, sterilization, and Digestive enzyme activity improvement. However, as a complex mechanical equipment, the normal operation of feed extruder cannot be separated from various precision accessories. This article will introduce some common feed extruder accessories and explore their key roles in improving feed processing efficiency and quality.
1. Screw and barrel:
The screw and barrel are the core components of the feed extruder, which generate a high-temperature and high-pressure environment through rotation and friction, causing raw materials to expand and deform. The screw and barrel are usually made of high-quality alloy steel, which has characteristics such as wear resistance, corrosion resistance, and high strength. At the same time, good sealing performance is required to prevent steam and gas leakage generated during raw materials and processing.
2. Bearings and sealing devices:
Bearings and sealing devices are important components to ensure the stable operation of feed extruder. High quality bearings can withstand high-speed rotation and large axial loads, while reducing energy loss and mechanical vibration. The sealing device ensures the Tight junction between the screw and the cylinder to prevent damage to mechanical parts caused by temperature, pressure and humidity changes.
3. Cutting knives and tools:
The feed extruder needs to cut the formed feed into appropriate lengths during the extrusion process to better meet the digestion and absorption capacity of animals. The selection and design of cutting knives and cutting tools directly affect the shaping and uniformity of feed. High quality cutting knives can provide clear and flat cuts, reducing the crushing and waste of feed.
4. Water cooling system:
In the high-temperature and high-pressure treatment process of feed extruder, it is necessary to effectively cool the screw and cylinder to avoid mechanical damage caused by overheating and excessive heating of raw materials. The water cooling system regulates and controls the working temperature of the extruder by circulating cooling water to maintain a suitable processing environment.
Conclusion:
Feed expander accessories play an important role in feed processing, as they not only affect processing efficiency, but also directly affect the quality and nutritional value of feed. Selecting high-quality accessories for assembly and maintenance can improve the stability and service life of the feed extruder, ensuring the safety and nutrition of livestock and poultry feed. Therefore, in the feed processing process, it is crucial to reasonably select and maintain the accessories of the feed extruder.
