Description

Technical Field

[0001] The invention relates to the technical field of Maotai-flavor liquor production, and in particular to a Maotai-flavor liquor steaming system. Background Art

[0002] The liquor brewing industry is a unique manufacturing industry in China. During the brewing process of Maotai liquor, the fermented lees (wine mash) is put into a steamer barrel (the upper steamer) and ethanol and various flavor substances are extracted through steamer barrel distillation. Therefore, the distillation process has an important impact on the quality of Maotai liquor, and the quality of distillation mainly depends on the quality of the upper steamer.

[0003] The steaming process must meet the requirements of "even spreading and steam detection". The traditional steaming method is that the steaming workers use a dustpan to spread the mash in the steamer according to the requirements of "light, loose, thin, uniform, flat and accurate". However, the traditional steaming method has the disadvantages of high labor intensity, high labor cost and low work efficiency. In addition, the steaming is also affected by the steaming speed, strength, technique, technical experience, sense of responsibility of the steaming workers, and the on-site management and supervision of the management personnel, so the quality of the steaming is difficult to maintain stability. Therefore, it is urgent to carry out research on the mechanized steaming of Maotai liquor.

[0004] At present, the mechanized steaming of Maotai liquor mainly adopts the method of steaming robots. For example, a steaming robot for winery production with application number 202121233541.0 includes a storage box for holding lees, a conveying component for conveying the lees to the distillation tank, and a leveling component for leveling the lees conveyed to the distillation tank is provided on the bracket, and the lees are scraped by a scraper. The lees are piled up unevenly during the transportation process, and the scraper can level the lees after scraping. Although mechanized steaming improves work efficiency. However, due to the high viscosity of the lees, it is difficult to spread the lees evenly by scraping with a scraper, which affects the distillation effect of the lees, and has not been well promoted and applied in practice.

[0005] The patent with the patent number 202210749011.4 discloses a charging system and a charging method. The charging system includes a feeding subsystem, a cloth spreading subsystem, a detection subsystem, and a control subsystem. The feeding subsystem is used to convey fermented grains. The cloth spreading subsystem includes a robot and a cloth spreading hopper. The robot has a six-degree-of-freedom robotic arm, and the cloth spreading hopper is arranged at the end of the robotic arm. The robotic arm can drive the cloth spreading hopper to move to the feeding subsystem to receive fermented grains, and can also drive the cloth spreading hopper to move to the steamer pot for cloth spreading. The detection subsystem, including an infrared camera and a three-dimensional camera, is used to obtain the infrared image and three-dimensional image of the surface of the fermented grains in the steamer pot, and obtain hot spot data and three-dimensional point cloud data. The control subsystem is connected to the detection subsystem and the cloth spreading subsystem, and controls the cloth spreading subsystem to spread the cloth based on the hot spot data and the three-dimensional point cloud data. This charging process is based on the manual charging method and uses the method of "pressing the fermented grains according to the steam pressure" for mechanized charging, which has great advantages compared with the simple method of scraping and leveling with a scraper. However, due to the relatively high viscosity of the distiller's grains, the method of moving the cloth spreading hopper of the cloth spreading subsystem to the steamer pot for cloth spreading still cannot evenly spread the distiller's grains. Therefore, high-end baijiu represented by Moutai still uses the manual charging method at present. In addition, the method of "pressing the fermented grains according to the steam pressure" does not change the problem of low charging efficiency, and there is a problem of slow charging speed for the chargers.
