Description
Technical Field
The utility model relates to the technical field of aquatic feeds, in particular to aquatic feed manufacturing equipment.
Background
The development of the aquatic compound feed technology rapidly advances the aquaculture industry. The traditional processes for manufacturing the compound feed comprise an expansion extrusion granulation process and a ring die extrusion granulation process. In the two processes, all raw materials are generally crushed, then are fully mixed and cured with high-temperature steam, and then are made into particles through a high-temperature and high-pressure process, and the obtained particles are dried and screened to obtain finished products. The granulated feed obtained by traditional granulation is advantageous for the preservation and transport of the feed, however, due to the high temperature process involved in the granulation process, this leads to the loss of the added heat-sensitive substances and limits the addition of some active substances (e.g. probiotics, heat-sensitive herbal medicines, antioxidants). Studies have shown that non-coated vitamin C only remains 50% active after heat treatment at 90 ℃, whereas common probiotics (e.g. lactic acid bacteria) are tolerated at temperatures below 60 ℃. Thus, the low temperature is maintained throughout the granulation process to ensure minimal loss of activity of these heat sensitive materials. However, the whole process of low-temperature granulation cannot eliminate the influence of original mixed bacteria in feed raw materials, some raw materials (such as corn, wheat and bran) inevitably pollute mould in the storage or processing process, and if the mould is not killed at high temperature, mycotoxin is easily generated in the later feed storage process, so that the feed quality is damaged, and the safety is low.
