The pellet stabilizer extends the "conditioning" time of the pellets by providing a heat and moisture retention environment, allowing the internal moisture and heat of the pellets to redistribute and continue acting. This process can significantly increase the starch gelatinization degree of the pellets, enhance the binding force inside the pellets, thereby greatly reducing the pellet powdering rate (PDI value can be improved by 2-5%), while also improving feed digestibility. The equipment structure is similar to a slow-speed mixer, with an insulating jacket to prevent excessive heat loss.
Specifications are expressed by volume and processing capacity (tons/hour). The retention time can be controlled within a certain range by adjusting the paddle angle and speed, typically 3-10 minutes. The supporting power is mainly used to drive the stirring shaft, not very high, from 5.5kW to 30kW. The equipment needs to be well sealed to maintain the internal saturated steam environment.
Mainly used in feed production with extremely high requirements for pellet hardness, for example: 1) Aquatic feed, which requires very high water stability; 2) Livestock and poultry pellet feed for long-distance transportation or multiple handlings, to reduce powder generated en route; 3) Formulations using a large amount of raw materials that are difficult to pelletize (e.g., wheat, barley). It is an effective post-conditioning equipment for improving the physical quality of pellet feed.
