Spray and whirl type aerobic fermentation tank

Abstract

The related rotary aerobic fermentor comprises a shell fixed on a base that contains hole for people and gas inlet/outlet, an inner coil pile and rotary shaft inside matched with gear; a mechanical stirrer on the shaft and both in the space formed by coil pipe, and a fixing frame. Wherein, it arranges a spraying mixer under an injector below the stirrer. This invention is simple, needs low energy consumption, and can improve fermentation performance.

Description

technical field [0001] The invention belongs to fermentation production equipment, in particular to a spray-rotating aerobic fermentation tank. Background technique [0002] At present, the equipment used in aerobic fermentation production is a general-purpose fermenter. Its structural feature is that a multi-stage high-power stirring device is installed in the tank. There are three ventilation methods. One is to set a single-hole tube at the bottom of the tank. The air holes of the hole tube are opened downwards to achieve the effect of eliminating the solid matter at the bottom of the tank while distributing air, but this will cause serious erosion of the bottom of the tank and a short service life of the tank; the second is to use a porous ring There are many circles of small holes at the bottom of the annular tube, and the air distribution is more uniform during use, but the material is easy to block the pores, resulting in incomplete sterilization; the third is to set 4...

[0002] At present, the equipment used in aerobic fermentation production is a general-purpose fermenter. Its structural feature is that a multi-stage high-power stirring device is installed in the tank. There are three ventilation methods. One is to set a single-hole tube at the bottom of the tank. The air holes of the hole tube are opened downwards to achieve the effect of eliminating the solid matter at the bottom of the tank while distributing air, but this will cause serious erosion of the bottom of the tank and a short service life of the tank; the second is to use a porous ring There are many circles of small holes at the bottom of the annular tube, and the air distribution is more uniform during use, but the material is easy to block the pores, resulting in incomplete sterilization; the third is to set 4-6 L-shaped branch pipes in the annular pipe, and the air outlets of the branch pipes are uniform. Facing the center line of the fermenter, its structure is simple, but there is a problem that it cannot completely eliminate the solid matter at the bottom of the tank; people have found in actual use that the general-purpose fermenter aeration device also has a direct proportional relationship between the diameter of the bubble and the amount of ventilation and direct steam flow. Disadvantages of violent vibration of the tank during actual consumption
