Embodiment Construction

[0014] In this example, taking a Qu room with an area of ​​25 square meters as an example, the method of hanging clothes in Daqu is introduced. The specific steps are:

[0015] Step 1: Put the large koji blank with a humidity not lower than 38.5% into a koji room with a humidity not lower than 70%;

[0016] Step 2: Place the koji on the koji frame of the koji room, sprinkle a layer of koji powder on the surface of the koji for inoculation, and then surround the koji frame with 2 to 3 layers of damp straw grids (moist but not dripping), Cover the frame with a layer of damp straw grid (damp but not dripping); there are 18 curved frames in the curved room, each curved frame is divided into five layers, and the interval between adjacent layers is 20cm, and the interval between adjacent curved blanks on the same layer 2~3cm;

[0017] Step 3. Sprinkle 100kg of water around the curved frame to keep the humidity and cool down, so that the humidity in the curved room is not lower than...

Abstract

The invention discloses a yeast coating method. The method is characterized in that yeast bases with the humidity being not lower than 38.5% are placed into a yeast room with the humidity being not lower than 70%; the yeast bases are horizontally placed on a yeast rack of the yeast room, yeast powder is spread for inoculation, and wet straw grids are used to cover the yeast bases in an enclosed manner; water is sprinkled for moist keeping and cooling, the temperature of the yeast bases slowly rises, water is sprinkled to the periphery of the yeast rack and door and window openness is controlled at the same time to allow the humidity of the yeast room to be not lower than 80% when the temperature of the yeast bases rises to 28 DEG C, and the temperature of the yeast bases is kept between 28-32 DEG C for at least 6 hours to complete yeast coating. The yeast coating method has the advantages that the method is convenient and effective and simple to operate, a coat layer can effectively forms on the surfaces of the yeast bases, contaminating microorganisms cannot easily invade into the yeast bases during the maturing process of the yeast bases, yeast fragrance and purity are increased, increasing of various physical and chemical indexes of mature yeast is promoted, and yeast quality and wine base quality are increased.

Description

technical field [0001] The invention relates to an operation method of Daqu hanging clothes for wine production. Background technique [0002] Daqu Hanging Clothes (clothes - scientific name Candida) is to form a protective film on the outer skin of the koji, making it difficult for bacteria to infiltrate during the maturation process of the koji, and can improve the fragrance and purity of Daqu. In the process of making koji, uncoated Daqu is easy to become raw skin koji (commonly known as dry skin), the skin of raw skin koji has fewer beneficial bacteria, the maturation time is too fast, the temperature is too strong, the incubation time is short, and the appearance quality is relatively poor. The physical and chemical indicators are relatively low; the hanging clothes Daqu is relatively poor in air permeability, and it is not easy for bacteria to infiltrate during the ripening process, which can slow down the progress of the culture process. Purity promotes the improveme...
