Aerobic fermentation apparatus of solid materials

Abstract

The invention discloses an aerobic fermentation apparatus, belongs to the field of fermentation equipment and provides an aerobic fermentation apparatus of solid materials, which can provide better heating uniformity for materials. The aerobic fermentation apparatus of solid materials comprises a stirring mechanism; the stirring mechanism comprises a stirring vane, a rotary shaft and support rods; the stirring vane is arranged spirally around the rotary shaft; an inflow passage and an outflow passage are arranged inside the rotary shaft; the inflow passage runs out of one end of the rotary shaft to form an inflow end; the outflow passage runs out of the other end of the rotary shaft to form an outflow end; the stirring vane is provided with a heat exchange passage along the stirring vane; connected passages are arranged respectively in the support rods at the tails of the two ends of the stirring vane. The stirring vane gains contact with a material to transfer heat when stirring the material; therefore, the material can be heated evenly during heating.

Description

technical field [0001] The invention relates to the field of fermentation equipment, in particular to an aerobic fermentation device for solid materials. Background technique [0002] The solid material aerobic fermentation device is a device used for aerobic fermentation of fermented materials. During the fermentation process, the materials often need to provide sufficient oxygen contact conditions, and at the same time, it is necessary to provide a certain fermentation temperature for the fermented materials to ferment. The current conventional treatment method is usually to set a corresponding heating layer structure on the outer peripheral side wall of the fermentation tank, and at the same time set a stirring mechanism inside the fermentation tank for stirring, so as to heat and stir the fermented material inside the fermentation tank to make it well Oxygen fermentation. However, when the fermentation tank is large, the material is only heated on the outer peripheral s...

AI Technical Summary

Problems solved by technology

However, when the fermentation tank is large, the material is only heated on the outer peripheral side wall of the fermentation tank, which is prone to the problem of uneven heating of the internal material

In addition, effective temperature control is not adopted in the process of heating materials at present, and the heating temperature is easily too high or insufficient, which affects the fermentation effect
