Problems solved by technology

Since the moth hatches larvae during grain storage, the above control measures are labor-intensive and the control effect is poor.
Spraying chemical pesticides in the warehouse will remain in the grain, destroying the microorganisms in the environment that are beneficial to wine making, affecting the quality and flavor of wine, and not conducive to the health of workers, easily causing secondary pollution and destroying the micro-ecological system of the wine making environment

Embodiment 1

[0029] A method for recovering CO produced in the fermentation process of Daqu wine 2 The method for preventing and controlling insect pests in grain comprises the following steps:

[0030] a. Use a stainless steel gas collection hood to collect CO 2 For gas, install a stainless steel gas collection hood:

[0031] The stainless steel gas collection cover is mainly composed of a gas collection cover body 1 with an open lower end, a gas delivery pipe 6 connected to the upper end of the gas collection cover body 1, and a desiccant 3 installed in a section of the gas delivery pipe 6; The lower opening of the body 1 corresponds to the shape of the upper opening of the Daqu wine fermentation cellar (the upper opening of the Daqu wine fermentation cellar is generally rectangular, and the length and width of the lower opening of the gas collecting hood cover body 1 are also the same as those of the Daqu wine fermentation cellar. The opening at the upper end is the same, and the heig...

Embodiment 2

[0039] A method for recovering CO produced in the fermentation process of Daqu wine 2 For the method for grain pest control, the desiccant 3 described in step a is discoloration silica gel, or other existing desiccant capable of absorbing water; during the use of discoloration silica gel, when the discoloration silica gel changes from blue before moisture absorption with the amount of moisture absorption After the increase gradually turns into light red, take it out, and regenerate the hygroscopic silica gel by drying method. The regeneration temperature is preferably controlled at 90-110°C;

[0040] Others are the same as embodiment 1, omitted.

Embodiment 3

[0042] A method for recovering CO produced in the fermentation process of Daqu wine 2 The method for preventing grain pests also includes a porous container sleeved in the air pipe 6, the desiccant 3 described in step a is placed in the porous container, so as to facilitate the placement and removal of the drying method;

[0043] Others are the same as embodiment 1 or 2, omitted.

Abstract

The invention discloses a method for recycling CO2 generated in a daqu liquor fermentation process for pest control for grain. The method is characterized in that a stainless steel gas colleting cover is used, and the stainless steel gas collecting cover mainly consists of a gas collecting cover body with an opening in the lower end, a gas delivery pipe communicated with the upper end of the cover body, and a drying agent; a material to be fermented is put into a daqu liquor fermentation pit to be covered with the stainless steel gas collecting cover, so that the opening in the lower end of the cover body is in butt joint with an opening in the upper end of the fermentation pit, and the fermentation pit is sealed with pit mud; and the gas collecting cover body is filled with CO2 gas generated by fermentation, and after the gas goes through the gas delivery pipe and the drying agent for drying, the gas is delivered to a grain storehouse, so that the smothering action of the CO2 gas is used for controlling grain moths and preventing grain mildew. Through the adoption of the method, the waste CO2 gas generated in the daqu liquor fermentation process is collected and utilized to realize comprehensive utilization of resources, so that the loss of grain in the storage process is reduced, the workload of fermentation pit management is reduced, the quality of daqu liquor can be improved, and the practicability is high.

Description

technical field [0001] The invention belongs to the control method of grain moth and the recycling of waste, and relates to a method for recovering CO produced in the fermentation process of Daqu wine. 2 A method for controlling pests in grain. The present invention reclaims by-product CO in the fermentation process of Daqu wine 2 (i.e. carbon dioxide) gas, using CO 2 Asphyxiation of the gas will recover the resulting CO 2 After the gas is dried, it can be used for the preservation of grain (that is, starchy raw materials) and the prevention and control of grain moths for wine making. It can also be used for the preservation of koji medicine and the prevention and control of koji and moths. Background technique [0002] Daqu Liquor is a liquor of various flavors obtained by crushing, moistening, steaming, cooling, mixing koji (using Daqu as a saccharification starter), putting it into cellars for fermentation, and distilling to obtain raw wine, which is then stored and bl...
