Description

Technical Field

[0001] This utility model relates to the field of feed production forming technology, specifically a fish feed pellet mill. Background Technology

[0002] Fish feed is a nutritionally formulated feed specifically designed for aquaculture. Its main components include plant proteins and energy sources such as fishmeal, soybean meal, corn, and wheat, along with added vitamins, minerals, and amino acids. Depending on the species being farmed, it can be categorized as floating, sinking, or slow-sinking feed, with particle sizes ranging from 0.5 mm to 10 mm. Modern fish feed emphasizes high efficiency and environmental friendliness, employing extrusion technology to improve digestibility (reaching over 85%) and reduce the feed conversion ratio (1.2-1.8). Special formulas also include probiotics, immune enhancers, and other functional ingredients to reduce aquaculture pollution (nitrogen emissions reduced by 30%). Feed forms include pellets and micro-pellets to meet the needs of various growth stages; for example, the protein content of starter feed for fry can reach over 45%, while adult fish feed contains approximately 28-35%.

[0003] Existing fish feed pellet mills often suffer from high moisture content, leading to spoilage and a short shelf life. Furthermore, during pelleting, they are prone to poor pelleting, resulting in loose, uneven pellets and excessive dust in the finished product. Utility Model Content

This allows the fish feed pellet mill to produce at a higher efficiency without affecting the forming effect of the fish feed.

[0018] This fish feed pellet mill, through its designed drying components, allows hot air from below and the sides to pass through ventilation plates and dry the formed fish feed when the pellets fall into the drying components during actual operation. The exhaust fan draws out the hot air, creating a chimney effect to accelerate air convection, which can more efficiently dry the moisture in the fish feed, ensuring the production quality and shelf life of the fish feed.

[0019] This feed pellet mill, through its designed vibrating screen component, allows the dried fish feed to be cooled and transported through the conveying component before entering the vibrating screen chamber for screening. Fine particles and dust are screened out and can be recycled. The formed high-quality fish feed pellets can be directly bagged, transported, and sold. Attached Figure Description
