Description

Technical Field

[0001] The utility model belongs to the technical field of rice wine fermentation, and particularly relates to a heat preservation device for rice wine fermentation. Background Art

[0002] Rice wine, also known as fermented glutinous rice or sweet wine, was formerly called "li." Made from glutinous rice, the primary ingredient is glutinous rice, hence the name "jiangmi wine." In northern China, fermented glutinous rice is commonly referred to as "rice wine" or "sweet wine." It's a sweet rice wine made by fermenting steamed glutinous rice with fermenter's yeast (a special microbial yeast). Modern rice wine is often produced in factories.

[0003] During the fermentation of rice wine, the fermentation temperature of the koji (which mainly contains two bacterial groups, rhizopus and yeast) is extremely important. It is necessary to ensure that the fermentation temperature is always maintained within the most suitable temperature range for rhizopus and yeast (the fermentation temperature is maintained at 30°C or 30±2°C). Therefore, certain insulation measures are needed to ensure the appropriate fermentation temperature. The heat loss inside the existing rice wine fermentation insulation device is relatively fast, and the insulation effect is poor, and it cannot provide a constant temperature for the internal fermentation tank or fermentation tank for a long time. Therefore, a heat preservation device for rice wine fermentation is needed to solve the above technical problems. Utility Model Content

A temperature sensor (not marked in the figure) is provided inside the insulation hollow cavity 112, the back of the insulation box 110 is connected to a water inlet channel 114, the water inlet channel 114 is connected to the inside of the insulation hollow cavity 112, the back of the insulation box 110 is further connected to a drainage channel 116, the drainage channel 116 is connected to the inside of the insulation hollow cavity 112 (wherein, the water inlet channel 114 is provided at the upper part of the back of the insulation box 110, and the drainage channel 116 is provided at the lower part of the back of the insulation box 110). The water inlet channel 114 is connected to a first water pump 115 , and the drainage channel 116 is connected to a second water pump 117 .

[0025] Specifically in this embodiment, the temperature sensor is set to keep the temperature inside the insulation box 110 at 30±2℃. When the temperature is lower than 28℃, the first water pump 115 draws the external waste hot water (generally, manufacturers condense and reflux the waste heat of high-temperature exhaust gas, cooling medium, waste steam and waste water generated in the rice wine blending workshop and distillation workshop) into the insulation hollow cavity 112 through the water inlet channel 114. When the temperature reaches 28℃, the water injection is stopped, so that the temperature is always maintained at 30℃ or 30±2℃. The circulation of hot water is achieved by cooperating with the drainage channel 116 and the second water pump 117. Such a setting has better insulation and wrapping properties, solving the problem of top exposure.

[0026] See also Figures 1 to 5As shown, the front of the insulation box 110 is provided with a sealed hatch 113, and the front of the insulation box 110 is connected to an inclined slope 118.

[0027] Specifically, in this embodiment, the provision of a thermal insulation layer 125 and an external thermal insulation layer 126 further enhances thermal insulation performance.

The provision of a filter element 121 allows for both influent and effluent filtration, and the provision of a threaded connection base 122 and a threaded connection sleeve 123 facilitates replacement and maintenance of the filter element 121.

[0028] The specific working principle of the present invention is as follows: when in use, hot water from the outside is connected to the water inlet channel 114, and is pumped into the inside of the heat-insulating hollow cavity 112 under the action of the first water pump 115, so that the temperature in the heat-insulating chamber 111 is higher than that of the outside. At the same time, the circulation of hot water is achieved under the action of the drainage channel 116 and the second water pump 117, and then the rice wine storage tank can be placed inside the heat-insulating chamber 111 to keep the rice wine warm.
