Description

Technical Field

[0001] This utility model relates to the technical field of feed processing equipment, specifically a low-temperature feed pelleting device. Background Technology

[0002] With the development of the aquaculture industry, farmers are increasingly demanding high-quality feed. At the same time, the animals raised are becoming more demanding in terms of the taste, flavor, and nutritional requirements of the feed. In order to enable the animals to gain weight quickly, there is currently a method of incorporating oil into extruded feed to promote rapid growth.

[0003] In existing feed pellet mills, the extrusion of material against the die generates significant heat during the pelleting process. This heat not only causes some material to expand and clog the die, but also denatures proteins and causes vitamin loss in the feed. Furthermore, the inability to control the temperature leads to the inactivation of microorganisms in the pelleted feed, resulting in insufficient feed efficiency and ultimately malnutrition in animals.
