Description

Technical Field

[0001] The invention relates to a fermentation device, in particular to a constant-temperature microbial feed fermentation device for animal husbandry. Background Art

[0002] Feed fermentation is mostly done by natural fermentation and fermentation with commercial lactic acid bacteria. With the development of animal husbandry, feed fermentation agents are also sought after by farmers. People not only pursue pork with better meat quality, but farmers are also looking for feed that can produce high-quality pork. Feed should be low-cost and good for the growth of pigs. Fermented feed is made by mixed fermentation of microorganisms (lactic acid bacteria, yeast and bacillus). The presence of aerobic bacteria such as yeast and bacillus creates an anaerobic environment for the growth and reproduction of lactic acid bacteria, and the large-scale reproduction of lactic acid bacteria produces lactic acid, which lowers the pH value. This gives the fermented feed product a sour aroma, and the feed is homogenized and fluffy after fermentation, thereby improving the palatability of the feed and stimulating the pig's feed intake.

[0003] In the livestock breeding process, microbial fermented feed plays an important role in improving animal health and growth performance due to its rich nutrients and probiotic content. However, traditional feed fermentation equipment, especially silo-type fermentation equipment, often has a problem during the fermentation process: due to gravity, the liquid (fermentation liquid) produced during the fermentation process tends to gather at the bottom of the silo, which not only affects the uniformity of the fermented feed, but also may cause the bottom feed to be too wet and deteriorate, and even cause microbial imbalance, reducing feed quality.
