Horizontal type rotary drum stirring, feeding and discharging device

Abstract

The invention relates to a horizontal type rotary drum stirring, feeding and discharging device which comprises a rotary drum body and a stirring device. A fermentation tank comprises a columnar cylinder body, a left sealing head and a right sealing head, the stirring device is arranged in the columnar cylinder body and is disconnected blades, the disconnected blades include sub-blades, and the sub-blades are fixed to the inner wall of the rotary drum body in an axial equally-spaced arrangement mode. The device further comprises a feeding and discharging device, wherein the feeding and discharging device is feeding and discharging screw blades, and the feeding and discharging screw blades are spiral blades fixed to one end of the inner wall of the rotary drum body. The horizontal type rotary drum stirring, feeding and discharging device has the advantages that the disconnected blades can spread a material and can also push materials towards two sides, a stirring effect can be achieved only through one-way rotation, a stirring effect is stronger compared with traditional common spiral blades, the fermentation efficiency is improved, the designed feeding and discharging screw blades achieve forward feeding and reverse discharging, the feeding and discharging speed is uniform and rapid, and the material level is flat.

Description

technical field [0001] The invention belongs to the field of fermentation equipment, and in particular relates to a horizontal rotating cylinder stirring and entering and exiting device. Background technique [0002] Solid fermentation refers to a biological reaction process with one or more microorganisms in an underwater soluble solid substrate with a certain humidity in the absence or almost no free water. Considering the essence of the biological reaction process, solid fermentation is a biological reaction process in which the gas phase is the continuous phase. The process of cultivating microorganisms on wet solid materials with no (or almost no) free water. In order to make the fermentation process uniform and efficient, the stirring device in the solid fermentation facility is particularly important; most of the existing horizontal solid state fermentation tanks use continuous helical screw blades, and the way to stir the materials is that the materials roll in the ...

Problems solved by technology

In order to make the fermentation process uniform and efficient, the stirring device in the solid fermentation facility is particularly important; most of the existing horizontal solid state fermentation tanks use continuous helical screw blades, and the way to stir the materials is that the materials roll in the fermentation tank as a whole. In the stirring mode, the material will agglomerate, and the material cannot fully contact with the air, which will easily cause uneven fermentation, thus affecting the fermentation quality
