Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the process of reaction in the fermentation tank in the prior art. In order to ensure that there is enough oxygen in the fermentation tank, it is necessary to continuously fill the fermentation tank with gas. In the process of filling gas, it has the disadvantage of large energy consumption, so as to provide a multi-layer box type aerobic fermentation equipment

Embodiment 1

[0046] This embodiment provides a multi-layer box-type aerobic fermentation equipment, including a fermentation box 1 and a tail gas purifier 14 communicated with the fermentation box 1 .

[0047] like figure 1As mentioned above, the fermentation box 1 has stacking plates 2 arranged in multiple layers along the vertical direction. Further, the fermentation box 1 includes, from top to bottom, a heating zone, a high temperature fermentation zone and a decomposed zone; a heating zone, a high temperature zone The ratio of the number of stacking plates 2 set in the fermentation area and the decomposing area is 1:2:3; the multi-layer arrangement of the stacking plates 2 can save land resources, and at the same time can avoid the mixing of different batches of materials, and the fermentation The heat generated by the process can be used efficiently.

[0048] The upper end of the fermentation box 1 has a feeding port 3, which is communicated with the outlet of the material elevator 4...

Embodiment 2

[0066] The present embodiment provides a fermentation method, using the multi-layer box-type aerobic fermentation equipment described in the embodiment, comprising the following steps:

[0067] After the material is inoculated and mixed, it is poured into the feeding port 3 through the elevator 4, and the material falls on the uppermost stacking plate 2 of the fermentation box 1. The material is preheated on each layer of stacking plate 2 . Specifically, in the preheating process, the heat generated by the high temperature fermentation zone is transferred upwards to preheat the materials that have just entered the box.

[0068] After the material stays in each stacker 2 for a period of time, it is transferred to the next layer of stacker 2; during the transfer process, the transfer starts from the bottom layer, and the time relay is used to control the interval between adjacent stackers 2. Turn over time is 5-10 minute. Before the turning plate is turned over, the mixer 7 is...

Abstract

The invention provides multi-layer box type aerobic fermentation equipment and a fermentation method, and belongs to the technical field of fermentation equipment. The multi-layer box type aerobic fermentation equipment comprises a fermentation box body and a tail gas purifier; according to the multi-layer box-type aerobic fermentation equipment, when the chamber of the tail gas purifier is in a reaction state, the chamber and the fermentation box body form a common space, the pressure in the space is reduced due to the reaction of part of gas, and in order to compensate the pressure, the gas in the fermentation box body is discharged; external gas automatically enters the fermentation box body through the first gas inlet to provide oxygen required by reaction; in the process, the gas is provided into the fermentation box body through the pressure difference, equipment is not needed, energy consumption is not needed, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of fermentation equipment, in particular to a multi-layer box-type aerobic fermentation equipment and a fermentation method. Background technique [0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microbial cells themselves, or direct metabolites or secondary metabolites. Among them, aerobic fermentation is a process that relies on obligate and facultative aerobic bacteria to reproduce and degrade organic matter under suitable moisture and oxygen conditions. The aerobic fermentation process can generate high temperature, kill pathogenic bacteria and weed seeds, so as to stabilize and harmless organic matter. [0003] Aerobic fermentation in the fermentation box can better control the oxygen, temperature and other conditions in the composting process, the decomposing effect is better, and the whole fermentatio...
