Description

Technical Field

[0001] The utility model belongs to the technical field of aquatic feed maturation equipment, in particular to an aquatic feed maturation device with heat circulation. Background Art

[0002] The aquatic feed maturation device is a device used to process aquatic feed. The aquatic feed maturation device uses heating and steam treatment to heat the starch, protein and other components in the aquatic feed at high temperature to destroy the structure, kill pathogens and enzyme activity, and improve the digestibility of the feed.

[0003] The heat energy generated by the existing aquatic feed maturation device during the maturation process is usually discharged into the environment in the form of steam or hot water. These heat energy emissions may take away a large amount of heat energy, causing energy waste and causing additional heat load on the environment. The existing aquatic feed maturation device usually lacks an effective heat recovery device and cannot recycle the heat energy. The heat energy generated during the maturation process is often not fully utilized, but directly discharged, resulting in heat energy waste and consumption of energy resources. Therefore, we hope to design an aquatic feed maturation device with a new structure to solve this problem. Utility Model Content
