[0002] The production of famous and high-quality Luzhou-flavor liquor adopts the traditional solid-state pit mud fermentation process, which highly depends on the pit pool. The quality of the pit mud in the pit pool plays a very important role in the quality of Luzhou-flavor liquor. The pit mud needs to be domesticated for a long time to meet the quality standard of high-quality old pit mud. The cultivation of high-quality artificial pit mud can accelerate the aging of the pit mud and enable new pit pools to produce high-quality liquor faster. During the cultivation process of artificial pit mud, relatively strict anaerobic conditions are required, and a relatively high temperature is needed, generally about 37°C, and no raw water can be seen.

[0003] Existing artificial pit mud cultivation devices are mostly covered with plastic films on open-air cement floors or use relatively complex pit mud cultivation devices. The former has poor anaerobic conditions during the cultivation process of artificial pit mud, is prone to water ingress, which causes the artificial pit mud to deteriorate, and is greatly affected by the external environmental temperature, and can only be cultivated in the high-temperature season in summer; the latter cultivation device is relatively complex, with a high upfront investment cost, is not easy to maintain and repair, and is not easy to be widely promoted and applied due to the influence of complex mechanical equipment.

[0004] Therefore, those skilled in the art urgently need to provide an artificial pit mud cultivation device that can achieve better anaerobic conditions during the cultivation process of artificial pit mud, is not affected by the external environmental temperature, is not infected by rainwater, and is easy to operate.

A circulating water cavity 2 is arranged inside the pit mud cultivation pool body 1. The circulating water cavity 2 includes a columnar pipe 21, a lower chamber 22 and a drainage pipe 23. A plurality of the columnar pipes 21 are arranged in a matrix. The bottoms of the plurality of columnar pipes 21 are communicated with the lower chamber 22, and the tops of the plurality of columnar pipes 21 are communicated with the drainage pipe 23. The top of the pit mud cultivation pool body 1 is arranged in a stepped shape, and the sealing cover 3 is buckled at the stepped position of the pit mud cultivation pool body 1. Artificial pit mud is filled inside the pit mud cultivation pool body 1.

[0022] Specifically, the columnar pipes 21 are arranged in a matrix, so that the pit mud is heated more evenly.

[0023] Specifically, 45°C sterile hot water is input into the circulating water cavity 2 through the circulating water inlet 4 and finally flows out from the circulating water outlet 5. The sterile water flows in the circulating water cavity 2 to ensure that the temperature for cultivating artificial pit mud is about 37°C. After two months of cultivation, the artificial pit mud ferments well, has no mildew and no strange smell, and has a strong ester fragrance and wine fragrance. The caproic acid functional bacteria in the artificial pit mud are twice that of traditional pit mud cultivation.

[0028] The circulating water inlet 4 is connected to a pump body, the pump body is connected to a water tank, and 45°C sterile water flows inside the circulating water channel 2.

[0029] A heat preservation layer 7 is connected to the inner wall of the pit mud cultivation tank body 1 to play a role in heat preservation.

[0030] The use process of the present utility model is as follows:

[0031] First, place the evenly mixed artificial pit mud inside the artificial pit mud cultivation device, cover the sealing cover 3, and seal it with sterile water;

[0032] Secondly, introduce 45°C sterile hot water, use the pump body to send the 45°C sterile hot water into the circulating water channel 2 through the circulating water inlet 4, and finally flow out from the circulating water outlet. The circulating water flows in the circulating water channel 2 to ensure that the artificial pit mud cultivation temperature is about 37°C. The excess gas generated during the artificial pit mud cultivation process is discharged through the one-way exhaust valve on the sealing cover 3.
