Bucket opening-free feeding device for bean pulp fermentation

Abstract

The invention discloses a tank-free feeding device for soybean meal fermentation, which comprises a fermentation tank with a fixed frame welded at the bottom, four equidistant rectangular chutes arranged on the inner wall of the top of the fermentation tank, and four rectangular The chute is slidingly connected with the same barrel cover with a cavity in the form of a disc structure. The top inner wall and the bottom inner wall of the barrel cover are provided with counterbore holes near the middle, and tapered rollers are welded in the two counterbore holes. Bearings, the inner rings of the two tapered roller bearings are plugged with the same transmission rod, and the outer wall of the end of the transmission rod away from the tapered roller bearings is welded with a spiral blade, and the top of the barrel cover is on the side close to the counterbore A metal pipe is welded on the surface, and the inner wall of the metal pipe is slidably connected with a top pipe, and the inner wall of the bottom of the barrel cover is welded with a motor fixing frame. The invention can mix and inoculate the composite bacterial liquid obtained after the reasonable proportioning of various bacterial liquids, shorten the fermentation time and reduce the production cost through the synergistic effect of multiple strains.

Description

technical field [0001] The invention relates to the technical field of soybean meal fermentation, in particular to a tank-free feeding device for soybean meal fermentation. Background technique [0002] Soybean meal is the remaining by-product after soybean oil is extracted. It is widely used in the feed industry because it is rich in protein, essential amino acids and various mineral nutrients. However, in the process of oil extraction and processing, the resulting soybean meal is often subjected to high-temperature treatment, resulting in serious protein denaturation and poor solubility, which is not conducive to digestion and absorption of animals; at the same time, soybean meal also contains many anti-nutritional factors, such as trypsin inhibitors , soybean hemagglutinin, goiterin, urease and anti-vitamins and other heat-labile anti-nutritional factors, phytic acid, oligosaccharides and glycinin and other heat-stable anti-nutritional factors, therefore, untreated Soybe...

Problems solved by technology

However, in the process of oil extraction and processing, the resulting soybean meal is often subjected to high-temperature treatment, resulting in serious protein denaturation and poor solubility, which is not conducive to digestion and absorption of animals; at the same time, soybean meal also contains many anti-nutritional factors, such as trypsin inhibitors , soybean hemagglutinin, goiterin, urease and anti-vitamins and other heat-labile anti-nutritional factors, phytic acid, oligosaccharides and glycinin and other heat-stable anti-nutritional factors, therefore, untreated Soybean meal is directly fed by animals, which can easily cause problems such as diarrhea and intestinal allergies, especially for young animals with immature intestinal functions; these characteristics greatly affect the feeding value of soybean meal; The treatment can well eliminate thermal instability and thermal stability anti-nutritional factors in soybean meal, and can well degrade macromolecular protein, and improve the digestion and absorption rate of animal feed; at present, soybean meal fermentation production technology mostly adopts original There are many deficiencies in the fermentation process and the quality of the finished product.
