Problems solved by technology

In addition, the efficacy value per unit weight of the etched koji will be reduced, which will further expand the economic losses caused by koji pests
[0004] In recent years, most of the liquor enterprises in my country have given up the chemical control methods (such as spraying) in the 1980s and 1990s due to the consideration of food safety factors in the control of distiller's yeast pests; but because there is no effective control method Therefore, enterprises often adopt more passive methods of management (such as insect killer lamps, etc.), the control effect is not ideal, and food loss is serious

Embodiment 1

[0047] Two distiller's yeast warehouses with better sealing conditions were set up, one of which was treated with low-concentration carbon dioxide and sprayed with Beauveria bassiana, and was set as the experimental room; the other was not treated in any way, and was set as the control room.

[0048] The koji blocks that have been fermented in the koji workshop and ready to be put into storage are neatly stacked in the two koji warehouses, and three koji stacks (400cm×135cm) are set up in each warehouse, with about 1,500 koji pieces in each koji stack. And there is a distance of 80cm between the curved pile and the wall.

[0049] In order to achieve an obvious contrast effect in a short period of time, and to prevent the interference of exogenous koji pests on the experimental effect, the experiment was carried out under the following conditions:

[0050] 1. Close the doors and windows of the distiller's yeast warehouse, so that the aspergillus in the two warehouses is produce...

Embodiment 2

[0060] Taking the warehouse-style distiller's yeast warehouse actually used by the enterprise as the experimental site, stack two such as Figure 14 The quasi-cube stack shown. One of them is the experimental song duo, and the other is the control song duo. The experimental quilts were completely covered with diatomaceous earth mulch, while the control quilts were left without any treatment. Other spaces in the warehouse are normally stacked with distiller's yeast.

[0061] The changes in the adult density of Quduo koji pests were observed three times a week. The observation points are one point on the bottom layer and one point on the middle layer on each side except the walls, a total of six observation points. The density of koji pest adults and the degree of koji etching are used to reflect the control effect of koji pests. The experimental period is from the end of August to the end of November.

[0062] Nearly a month after the experiment, a large number of corpses ...

Abstract

The invention discloses a non-chemical distiller's yeast pest control method and a three-stage distiller's yeast storage method based on the non-chemical distiller's yeast pest control method. The invention is characterized in that the control method is composed of the following approaches: distiller's yeast warehouse oxygen content is reduced through controlled atmosphere, such that the reproduction rate and adult rate of the distiller's yeast pests are inhibited; the distiller's yeast pests are killed with beauveria and diatomaceous earth; and the distiller's yeast pests are killed with trapping lamps. During a distiller's yeast storage period, with a combination of the above control approaches, adult pest number is gradually reduced through three stages. Distiller's yeast pest control is carried out according to actual situations of different stages of the distiller's yeast. With the distiller's yeast pest control and distiller's yeast storage methods provided by the invention, distiller's yeast pests can be effectively killed, distiller's yeast storage quality can be improved, white spirit loss can be reduced, and production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to a method for controlling distiller's yeast pests and a method for storing distiller's yeast. Background technique [0002] With the continuous growth of liquor consumption in the market, the annual liquor output of major liquor companies is increasing year by year, and the consumption of distiller's yeast must also increase thereupon; however, the production of distiller's yeast has a strong seasonality. The storage capacity is increasing year by year. In the process of accumulation and storage of distiller's yeast, there are generally insects, which not only causes a large loss of distiller's yeast, but also reduces the activity indicators such as saccharification power and fermentation power of distiller's yeast, which affects the production efficiency of liquor and increases the production cost of enterprises. At the same time, it also has a negative impact on the...
