Despumating and defoaming device suitable for fermenting tank

Abstract

The invention relates to the field of foam eliminating devices, in particular to a despumating and defoaming device suitable for a fermenting tank. The despumating defoaming device is arranged on an opening of the fermenting tank, and the opening of the fermenting tank is connected with a gas collecting tank. The despumating and defoaming device comprises a screen net and a stirring and crushing assembly, wherein the screen net is erected on the opening of the fermenting tank; the stirring and crushing assembly consists of a rotary rod, blades, a motor, an air guide pipe and an air suction pump; the rotary rod and the blades are respectively of a hollow structure; the rotary rod is rotationally connected with the screen net, one end of the rotary rod penetrates through the screen net and extends into the fermenting tank, the blades are arranged at the end of the rotary rod and are communicated with the rotary rod, and a plurality of holes are formed in each blade to enable the interior and exterior of each blade to be communicated; the other end of the rotary rod is connected with the motor, and is connected with the air guide pipe, one end of the air guide pipe is rotationally connected and communicated with the rotary rod, and the other end of the air guide pipe is communicated with the gas collecting tank through the air suction pump. The despumating and defoaming device has the advantages that in combination with the screen net, the defoaming efficiency is improved, and the waste of fermenting materials is reduced.

Description

technical field [0001] The invention relates to the field of foam elimination devices in fermentation tanks, in particular to a defoamer and defoamer suitable for fermentation tanks. Background technique [0002] During the fermentation of cassava to alcohol, the fermenter produces CO 2 gas, production personnel need to put the CO 2 The gas is discharged to ensure the normal operation of the fermenter and the quality of cassava fermented into alcohol, due to CO 2 The gas exists in the form of gas in the fermenter or is wrapped in the foam generated in the fermenter, so when the CO is discharged 2 During the process of gas, most of the connected foams are sucked together, but during the suction process, the fermentation materials mixed in the foams will be sucked away, which causes the waste of fermentation materials and reduces the fermentation quality in the fermenter . [0003] At present, in order to prevent the fermentation material from being sucked away with the fo...

[0005] However, when there is too much foam in the fermentation tank, the foam cannot be completely eliminated by using the wire mesh demister only, which will cause the foam to be discharged together with the gas, resulting in a waste of fermentation materials, or, it will also cause the wire mesh demister There are too many residual foam droplets on the surface, which will also cause waste of fermentation materials. Therefore, it is necessary to propose a defoamer and defoamer that can effectively improve the efficiency of foam removal and reduce the waste of fermentation materials.
