Spiral type fermentation turner

Abstract

The invention relates to a spiral type fermentation turner which is applied to an aerobic fermentation process of various organic materials including fertilizers, feeds and foods, and realizes forcedventilation oxygen-increasing operation of the materials simultaneously when turning and stirring the fermentation materials. The spiral type fermentation turner comprises a walk device arranged on astand of the spiral type turner, turning and stirring devices and a forced ventilation oxygen-increasing device and is characterized in that one or more rows of turning and stirring devices are installed below the stand, tow rows of branch ventilating pipes which extend into the bottom of the fermentation materials are vertically and symmetrically installed at the axial line position in the middleof two adjacent turning and stirring devices in the same row, and gas supply equipment is connected with the branch ventilating pipes through a main ventilating pipe. When turning and stirring the fermentation materials, the spiral turner can ensure true realization of forced ventilation and oxygen increasing to the materials, increase the smoothness and the safety of walking of the turner, enable the fermentation period to be shortened by over 70 percent and the turnover rate of a fermentation workshop to be enhanced by over 50 percent, also lower the energy consumption in the fermentation and production process by over 50 percent and dramatically enhance the economic benefit of an enterprise.

Description

technical field [0001] The invention belongs to the field of fermentation equipment and is applied to the aerobic fermentation process of organic materials such as various fertilizers, feeds and foodstuffs, and specifically relates to a device for realizing forced ventilation and oxygenation of materials while stirring the fermentation materials. Background technique [0002] At present, when aerobic fermentation is carried out on organic materials such as fertilizers, feed and food, it is often necessary to adopt a tank-type fermentation method, and to match it, a screw-type mixer is used to timely mix the fermented organic materials during the fermentation process. Ventilation and oxygenation. However, the existing spiral turning mixer is affected and restricted by its structure and working principle, and the materials are only turned up and down in situ, which can only achieve the purpose of turning. Since fresh air cannot enter the interior of the materials during the m...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the actual application process, that is, after installing ventilation pipes on both sides of the screw shaft, the resistance of the mixer will increase when it travels in the material, so that when the thickness of the fermented material is large, the mixer will not work properly. Moving forward, overturning occurs, so on the one hand, the accumulation thickness of the fermentation material is limited, and on the other hand, the stability and safety of the turning machine are affected
