Precautions for Using Large Feed Extrusion Machinery

Extruder for puffed food still retains a lot of nutritional value for many raw material processing, but many aspects need attention during the puffing process. The time required for control, as well as temperature and humidity, must be considered to maintain product quality stability. What issues should be noted when puffing soybeans? Below, the editor will take you through the precautions for feed puffing machinery.

1. The moisture content of soybeans is 12.5%-14%, and the impurity content should not exceed 25%.

2. The particle size of materials entering the chamber is greater than 3-6 millimeters to achieve consistent quality and improve production capacity.

3. During production, the residence time of raw materials indoors and the temperature inside the container should be recorded to ensure consistent quality. Generally, the residence time of raw materials indoors should not exceed 30 seconds, the temperature duration is 5 to 6 seconds, the first-stage temperature is 130 to 145°C, and the moisture content of the product is less than 8%. An appropriate amount of water can also be added during processing.

4. The temperature of the extruded whole soybean should be reduced as quickly as possible to prevent over-maturation of the product and destruction of the protein. It should be noted that products with higher moisture content after wet extrusion require sufficient drying and cooling to ensure that the moisture reaches a safe storage level.

Extruded feed can reduce the risk of animal diseases, improve animal production performance, enhance the efficacy of low-quality raw materials, and lower feed costs. The above is the equipment shared by the editor for use on feed extruders, hoping it will be helpful to everyone!
