Many factors affect the quality of feed produced in sheep feed pellet. Such factors include the raw materials and pellet processing.The various stages of the pelleting process affected by the water content include: grinding, mixing, conditioning, pellets making and pellets cooling.
Raw materials moisture content
Moisture content is essential in the process of sheep feed pellet as it is required for intermolecular forces development. Due to the low temperature in winter and spring, feed manufacturers often use new harvest corn, which has a relatively high moisture content. After pelleting, the moisture content is about 13%, which can basically meet the quality control requirements. However, in summer and autumn, the moisture content of feed ingredients is between 11% and 13%. In addition to the high temperature, part of the moisture content of feed ingredients is lost in the process of crushing, pelletizing, and pre-treatment, resulting in the moisture content of finished feed products being 9% to 11%.
Feed Grinding Process
This process is vital for the sheep feed pellet production.it is found that the moisture loss of raw materials after pulverization increases significantly with the reduction of the raw material pulverized particle size. As the moisture content of the raw material increases, the crushing efficiency is also significantly reduced, and the energy consumption will also increase. The water loss during the crushing of raw materials is generally about 0.5%.The highest moisture loss for various fodder materials is 1%.
