Oblique-drum vacuum solid fermentation tank internally provided with heat-exchange helical blade

Abstract

The invention discloses an oblique-drum vacuum solid fermentation tank internally provided with a heat-exchange helical blade. The oblique-drum vacuum solid fermentation tank internally provided withthe heat-exchange helical blade comprises a tank body and a base, wherein a hollow stirrer used for stirring and mixing is arranged on the inner wall of the tank body, and a bearing rail and a drivengear which surrounds the tank body are arranged at the front end of the tank body; a hollow radical shaft is arranged at the bottom end of the tank body, and a bearing is arranged outside the hollow radical shaft; a vacuumizing rotating connector is arranged at the top end of the tank body, and the vacuumizing rotating connector is communicated with a vacuum pump; a first supporting base, a secondsupporting base and a motor installation base are arranged on the base, a bearing wheel matched with the bearing rail is arranged on the first supporting base, the second supporting base is movably connected with the bearing, a heat-exchange medium rotating connector is arranged at the tail end of the bearing, a driving motor is arranged on the motor installation base, and a driving gear matchedwith the driven gear is arranged on the driving motor. The oblique-drum vacuum solid fermentation tank internally provided with the heat-exchange helical blade has internal and external double heating / cooling, double stirring and back mixing functions, capable of completing vacuum drying at the same time, and is suitable for multi-purpose non-in-place sterile solid fermentation production.

Description

technical field [0001] The invention belongs to the technical field of feed or bio-organic fertilizer fermentation equipment used in agriculture and animal husbandry, in particular to an inclined drum type vacuum solid-state fermentation tank with built-in heat-exchangeable spiral blades. Background technique [0002] Fermented feed refers to that under artificial control conditions, microorganisms can decompose or transform various vegetable, animal and mineral anti-nutritional factors in feed materials through their own metabolism, so as to form nutrients that are easier for animals to eat, digest and absorb. And non-toxic feed. This kind of microorganisms can produce and accumulate a certain concentration of organic acids and a certain amount of live bacteria after being fermented in the feed, which can increase the feed intake of animals, promote digestion and absorption, improve the utilization rate of feed, and at the same time enhance the immunity of animals. force. ...

Problems solved by technology

[0005] The patent with the application number 201721070528.1 discloses a stirring tank capable of mixing and heating. It is equipped with a heating device and a stirring device inside. The heating device and the stirring device can realize the functions of mixing, stirring and heating of materials. However, this patent is Heating is carried out by installing a heat exchanger on the inner wall of the tank, which makes the heating not uniform enough and the temperature uncontrollable; the stirring impeller of this patent is a triangular impeller, which also makes the stirring insufficient, and further improvement is needed

The patent with the application number 201621202661.3 discloses a feed fermenter, which is provided with a head at both ends, a jacket on the outer wall, and a temperature and humidity sensor inside, which can only monitor the temperature and humidity, but cannot control it well. The temperature in the tank cannot provide a constant temperature fermentation environment, and there are only three stirring blades on the stirring shaft, the stirring is not uniform, and further improvement is needed
