Description

Technical Field

[0001] The utility model relates to the technical field of feed fermentation tanks, in particular to a solid-state fermentation tank for feeding microorganisms. Background Art

[0002] Biological feed can be divided into two major production processes: dry process and wet process. Dry process refers to the production process in which enzyme preparations, probiotics and other tissues are added to dry matrix raw materials (without or very low free water). Wet process refers to the production process in which enzyme preparations and probiotics are added to biological feed when the water content of matrix raw materials (free water, excluding cell-bound water) is high. Regardless of the process, probiotic microorganisms need to undergo a certain fermentation to ensure that the matrix raw materials are full of probiotics.

[0003] In the prior art, there is a Chinese utility model patent with publication number CN202321006158.0 and name: A solid-state fermentation feed fermentation reaction equipment. It uses an insulation jacket to heat the fermentation tank, and can also directly pass hot air into the fermentation tank to heat the feed and promote fermentation. However, the equipment can only gradually heat the feed from the outside. Even if hot air is directly passed into the fermentation tank, it is difficult for the hot air, as a light gas, to enter the central part of the feed in the fermentation tank, resulting in slow heat transfer efficiency and insufficient heat transfer. Utility Model Content

[0007] A further technical solution is that the turning plate is arranged tilted.

[0008] A further technical solution is: the turning plate is made of ceramic material.

[0009] A further technical solution is that a rubber scraper is installed on the outer end of the turning plate.

[0010] A further technical solution is: the heating equipment is composed of a water tank, a circulation pump and a heater which are connected in sequence.

[0011] A further technical solution is: the heater is a gas water heater.

[0012] A further technical solution is that a plurality of water inlets are arranged at both ends of the rotating shaft.
