Embodiment Construction

[0032] In this example, taking a 750cm×660cm koji room as an example in summer, the method of cultivating medium-high temperature Daqu in the room is introduced:

[0033] Step 1: Preparation

[0034] There is a door on the front side of the curved room, and a window is installed on the back side of the curved room opposite to the door;

[0035] The day before putting the koji into the koji room, the koji room should be cleaned first, and the reed mats and grass fences should be tidied up. Use reed mats with a thickness of 0.2-0.3cm to completely cover the ground of the Qufang, and spray 1Kg / m evenly on the reed mats according to the area of ​​the reed mats 2 of water to control the room temperature and humidity.

[0036] Step 2: Lying down to absorb sweat

[0037] Place the first layer of curved frames in the curved room. The adjacent curved frames are separated by 15cm, and the adjacent curved frames are spaced by 8cm. With an interval of 3cm, lay the curved blanks on the...

Abstract

The invention discloses a room culture method of medium-high temperature yeast. The method comprises eight steps of preparation, yeast laying and sweat collection, fermentation temperature control, airing and cooling, low-temperature cultivation, slow rise of controlled temperature, high-temperature aroma increasing and post-fire moisture discharge. The room culture method of medium-high temperature yeast, disclosed by the invention, has the advantages of simplicity and convenience in operation and short cycle; through air flow and cooling moisture discharge, the number of grass grids is controlled, and the maintaining of temperature and moisture is facilitated; and meanwhile, different operation methods are adopted for different periods, so that the yeast blank fermentation is sufficient, the maturity is uniform and consistent, the space between yeast blocks is reduced, the aims that the yeast in each room is good and each yeast block is aromatic are basically achieved, and physical and chemical indexes are improved to the same degree.

Description

technical field [0001] The invention relates to a method for cultivating medium-high temperature daqu in a house. Background technique [0002] The invention discloses an operation method for cultivating Daqu, which mainly aims at the problems of inconsistent maturity of Daqu, low physical and chemical indexes, difficult process control and the like, and the invention of an operation method. [0003] Daqu plays a vital role in the production of liquor and is known as the "soul of liquor". Daqu is a whole that contains multi-bacteria, multi-enzyme and complex aroma substances. These three systems promote and complement each other. When making koji, the raw materials for koji making are crushed, moistened, pressed, and cultured in a room to allow microorganisms to reproduce and produce glucoamylase, alcoholic enzymes and aromatic substances needed for wine making, and then air-dried and stored to form Daqu. Among them, cultivation in the house is a crucial step, but this ste...
