Description

Technical Field

[0001] The utility model relates to the technical field of liquor brewing, in particular to an air inlet device for a cooling machine. Background Art

[0002] Fermented grains usually refer to grains that are fermented after cooking, such as sorghum, wheat or rice. They are mainly used as raw materials for distilling wine in the winemaking process.

[0003] During the brewing process of liquor, the mash needs to be lowered to the required range, which is generally achieved through a cooling machine. The main purpose of cooling is to lower the cooked grain or mash to a suitable temperature to ensure that the brewing microorganisms in the added koji can be active under the optimal temperature conditions.

[0004] During the cooling process, in order to improve the cooling efficiency of the mash, gas will be introduced to blow the mash. At the tail end of the cooler, the low-temperature gas will be used to cool the mash so that the mash is finally in the required temperature range. When the mash enters the initial position of the cooler, the temperature of the mash is at its peak. When the ambient temperature is high, it takes a long time to use the ambient gas to reduce the temperature of the mash to the required range, and then transport this part of the mash to the next part of the cooler for cooling again, resulting in a longer time required to cool the mash.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-3 As shown, an air inlet device for a cooling machine includes a first air inlet device 5 and a second air inlet device 4. The air outlet end of the first air inlet device 5 is connected to a heat exchanger 15. The air outlet end of the heat exchanger 15 is connected to a first air outlet hood 1 through a first pipe 13. The air outlet end of the second air inlet device 4 is connected to a second air outlet hood 2 through a second pipe 12. The first air inlet device 5 is connected to a third air outlet hood 3 through a fourth pipe 11.

[0027] In this embodiment, the first air outlet hood 1, the second air outlet hood 2 and the third air outlet hood 3 are fixed above the conveying mechanism of the cooling machine in sequence. When the cooling machine conveys the mash, the mash will pass through the third air outlet hood 3, the second air outlet hood 2 and the first air outlet hood 1 in sequence. During this process, the first air inlet device 5 and the second air inlet device 4 start to work. The first air inlet device 5 sucks the external gas into the first pipe 13 through the heat exchanger 15, and then conveys it to the first air outlet hood 1. Since there is a refrigerant (cooling water) flowing in the heat exchanger 15, the temperature of the gas is relatively low after being reduced by the heat exchanger 15, so the gas entering the first air outlet hood 1 can cool the mash at a relatively low temperature.

[0028] Moreover, after the gas discharged from the first air outlet hood 1 cools the mash corresponding to the first air outlet hood 1, it will also enter the third air outlet hood 3 through the fourth pipe 11, so as to cool down the mash corresponding to the third air outlet hood 3. Since the third air outlet hood 3 is installed at the initial position of the cooling machine, the temperature of this part of the mash is relatively high, and the third air outlet hood 3 uses the gas in the first air outlet hood 1. After the gas is cooled by the heat exchanger 15, although it has exchanged heat with the mash corresponding to the first air outlet hood 1, its temperature is still relatively low. Therefore, using this gas to cool down the mash corresponding to the third air outlet hood 3 for the second time can also play a good cooling role, thereby improving the utilization rate of the low-temperature gas.

[0029] The second air inlet device 4 can directly deliver the air in the workshop into the second air outlet hood 2 through the second pipe 12, so the fermented grains corresponding to the second air outlet hood 2 can be cooled;

[0030] To summarize, the mash is conveyed on the cooling machine, first passing through the third air outlet hood 3, the second air outlet hood 2 and the bottom of the first air outlet hood 1, and the cooling gas used by the third air outlet hood 3 is derived from the low-temperature gas used by the first air outlet hood 1. Therefore, the temperature of the mash can be greatly reduced in a short time. The second air outlet hood 2 uses natural wind to cool the mash, which can further reduce the temperature of the mash. The first air outlet hood 1 uses the gas cooled by the heat exchanger 15 to cool the mash, so that the temperature of the mash is reduced to the required range to complete the cooling operation of the mash.

[0031] Among them, Figure 1 As shown, the fourth pipe 11 is connected to an exhaust fan 14 , and the exhaust fan 14 is used to suck the gas in the first air outlet hood 1 into the fourth pipe 11 , and transport this part of the gas to the third air outlet hood 3 through the fourth pipe 11 .

[0032] Among them, Figure 1 As shown, the second pipe 12 is also connected to the third pipe 10, the end of the third pipe 10 is connected to the third air outlet hood 3, the fourth pipe 11 is provided with a first valve 6, the third pipe 10 is provided with a second valve 8, the fourth pipe 11 is also provided with a first thermometer 7, and the third pipe 10 is provided with a second thermometer 9;

[0033] The temperatures in the fourth pipe 11 and the third pipe 10 can be known by the first thermometer 7 and the second thermometer 9. Therefore, when the temperature in the fourth pipe 11 is lower than the temperature in the third pipe 10, the first valve 6 is opened and the second valve 8 is closed, so that the third air outlet hood 3 uses the gas from the first air outlet hood 1. When the temperature in the fourth pipe 11 is higher than the temperature in the third pipe 10, the first valve 6 should be closed and the second valve 8 should be opened, so that the third air outlet hood 3 uses the gas delivered by the second air inlet device 4, thereby ensuring that the third air outlet hood 3 uses low-temperature gas when the device is in an environment with low room temperature.

[0034] Among them, Figure 2As shown, the first air outlet hood 1, the second air outlet hood 2 and the third air outlet hood 3 have the same structure and all include a hood body 102. Air outlets 101 are opened at both ends of the hood body 102. A plurality of groups of air outlet pipes 103 are arranged in the hood body 102. The plurality of groups of air outlet pipes 103 are all connected to an air collecting box 104. A plurality of air outlet holes are arranged on the air outlet pipe 103. The air collecting box 104 of the first air outlet hood 1 is connected to the first pipe 13, the air collecting box 104 of the second air outlet hood 2 is connected to the second pipe 12, and the air collecting box 104 of the third air outlet hood 3 is connected to the fourth pipe 11 and the third pipe 10. Therefore, the gas emitted by the first air outlet hood 1, the second air outlet hood 2 and the third air outlet hood 3 can contact with the mash more evenly, thereby improving the cooling efficiency.

[0035] Among them, Figure 3 As shown, the first air inlet device 5 and the second air inlet device 4 have the same structure and both include a shell 401 with a side opening, and a fan 402 is connected to the shell 401. When the fan 402 is working, it can transport the gas into the shell 401 and then transport it to the corresponding air outlet hood through the corresponding pipe.

[0036] Working principle: the first air outlet hood 1, the second air outlet hood 2 and the third air outlet hood 3 are fixed above the conveying mechanism of the cooling machine in sequence. When the cooling machine conveys the mash, the mash will pass through the third air outlet hood 3, the second air outlet hood 2 and the first air outlet hood 1 in sequence. During this process, the first air inlet device 5 sucks the external gas into the first pipe 13 through the heat exchanger 15, and then conveys it to the first air outlet hood 1. Since there is refrigerant flowing in the heat exchanger 15, the temperature of the gas is lower after being reduced by the heat exchanger 15. Therefore, the gas entering the first air outlet hood 1 can cool the mash at a lower temperature. In addition, after the gas discharged from the first air outlet hood 1 cools the mash corresponding to the first air outlet hood 1, it will also enter the third air outlet hood through the fourth pipe 11. hood 3, thereby cooling the mash corresponding to the third air outlet hood 3. Since the third air outlet hood 3 is installed to the initial position of the cooler conveying, the temperature of this part of the mash is relatively high, and the third air outlet hood 3 uses the gas in the first air outlet hood 1. After the gas is cooled by the heat exchanger 15, although it has exchanged heat with the mash corresponding to the first air outlet hood 1, its temperature is still relatively low. Therefore, using this gas to cool the mash corresponding to the third air outlet hood 3 for the second time can also play a good cooling effect, thereby improving the utilization rate of the low-temperature gas. The second air inlet device 4 can directly send the gas from the workshop into the second air outlet hood 2 through the second pipe 12, so the mash corresponding to the second air outlet hood 2 can be cooled.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
