Disposed within the first closed conduit 100 is a conveyor belt 130; a first feeding port 101 is formed in one end of the first closed pipeline 100 above the first conveying belt 130, an exhaust port is formed in the upper surface of the first closed pipeline 100, and a first discharging port is formed in the lower surface of the other end of the first closed pipeline 100; the second closed pipeline 200 is overlapped on the lower side of the first closed pipeline 100, a second conveying belt 210 is arranged in the second closed pipeline 200, the second conveying belt 210 and the first conveying belt 130 extend in the same direction, and a second feeding port 201 is formed in the upper surface of one end of the second closed pipeline 200 corresponding to the first discharging port, so that grains on the first conveying belt 130 can enter the second conveying belt 210 through the first discharging port and the second feeding port 201; the other end of the second closed pipeline 200 is provided with a second discharge hole below the second conveying belt 210; the refrigeration device comprises a refrigeration module 410, a first conveying pipeline 420 and a second conveying pipeline 430, wherein the refrigeration module 410 can generate cold air, the refrigeration module 410 is communicated with a first air inlet of the first conveying pipeline 420, a first air outlet 421 of the first conveying pipeline 420 is communicated with the second closed pipeline 200 to refrigerate grain on the second conveying belt 210, and the second conveying pipeline 430 is used for communicating the second closed pipeline 200 and the first conveying pipeline 420 so that the cold air in the second closed pipeline 200 is conveyed into the first conveying pipeline 420.
When the grain stillage airing machine starts to be used, the steamed grain stillage is put on the first conveying belt 130 through the first feeding hole 101 on the first closed pipeline 100, so that the grain stillage moves towards the first discharging hole along with the conveying belt. The grain tank falls downwards after passing through the first discharge hole, and then falls onto the second conveying belt 210 through the second feed inlet 201, and the grain tank is conveyed by the second conveying belt 210 and then is output to the outside through the second discharge hole, so that the cooling path of the grain tank is effectively prolonged, the cooling time of the grain tank is prolonged, the cooling effect is improved, and the temperature of the grain tank output by the second conveying belt 210 is suitable for the processes of adding distiller's yeast, fermenting and the like subsequently. In addition, the first closed pipeline 100 and the second closed pipeline 200 reduce the occupied area of the grain stillage airing machine, reserve arrangement and operation space for equipment of other processes of white spirit brewing, and improve the utilization rate of working space.
In the process of conveying the grain stillage on the first conveying belt 130 and the second conveying belt 210, the refrigerating module 410 generates cold air and conveys the cold air into the second closed pipeline 200 through the first conveying pipeline 420, and the cold air diffuses in the second closed pipeline 200 to gradually cool the grain stillage conveyed on the second conveying belt 210, so that the utilization efficiency of cold air and cold energy is improved. After cooling the grain on the second conveyer belt 210, the cold air in the second closed pipeline 200 is conveyed into the first closed pipeline 100 through the second conveying pipeline 430, so that the residual cold energy of the cold air is utilized to cool the grain on the first conveyer belt 130, thereby realizing multi-stage utilization of the cold energy of the cold air, improving the utilization efficiency of the cold air, and enabling the grain to realize stable cooling.
Referring to fig. 1 and 2, in the present embodiment, the first closed pipe 100 is located on the upper side of the second closed pipe 200, and the second closed pipe 200 encloses the first conveyor belt 130, which can effectively prevent external dust, bacteria and the like from entering the grain tank, so as to facilitate the subsequent steps of adding distiller's yeast and fermenting, and ensure the reliability, safety and stability of the alcoholic beverage product during brewing.
One end of the first closed pipeline 100 is provided with a first feeding port 101, and the other end of the first closed pipeline 100 is provided with a first discharging port. The first feeding hole 101 is located above the first conveying belt 130, so that the grain tank falls onto the first conveying belt 130 when passing through the first feeding hole 101, so that the grain tank is scattered after impacting the first conveying belt 130, the contact area of the grain tank with cold air is increased, and the cold air can be fully contacted with the grain tank, so that the subsequent cooling process is facilitated.
In some embodiments, the first feed port 101 is disposed at an end face of the first closed conduit 100. An inclined baffle 340 is arranged between the first feed inlet 101 and the first conveying belt 130, one end of the inclined baffle 340 is connected to the lower side wall of the first feed inlet 101 on the first closed pipeline 100, and the other end of the inclined baffle 340 is located below the first feed inlet 101 and above the first conveying belt 130. After passing through the first feeding port 101, the grain stillage flows through the inclined baffle 340 to enter the first conveyor belt 130, so that the grain stillage entering the first closed pipeline 100 through the first feeding port 101 is prevented from falling to the periphery side of the first conveyor belt 130.
The upper side wall of the first closed pipeline 100, which is close to the first feeding port 101, is provided with an air outlet for discharging air in the first closed pipeline 100, so as to effectively prevent a large amount of condensed water generated in the grain tank in the first closed pipeline 100 during the cooling process. And, it is also possible to effectively prevent condensed water from being generated on the side wall of the first closed duct 100.
In some embodiments, two exhaust ports are disposed on the upper side wall of the first closed conduit 100 near the first feeding port 101, and the two exhaust ports are closely arranged along the extending direction of the first closed conduit 100. The two exhaust ports are a first exhaust port 103 and a second exhaust port 104, the first exhaust port 103 is arranged close to the first feeding port 101, and the second exhaust port 104 is positioned at one side of the first exhaust port 103 away from the first feeding port 101.
The first exhaust port 103 is used to exhaust the gas released by the grain drops onto the first conveyor 130. The second exhaust port 104 extends along the extending direction of the first conveyor belt 130 on the first closed duct 100 to sufficiently exhaust the vapor released from the grain tank above the front section of the first conveyor belt 130. Because the higher the temperature of the grain tank is, the faster the molecular movement speed is, when the grain tank with higher temperature exchanges heat with cold air, the better the heat exchange effect is, so that the better the cooling effect of the grain tank at the front section in the first conveying belt 130 is, the more water vapor is released by the grain tank at the front section in the first conveying belt 130, and at this time, the water vapor at the position can be better discharged by the arrangement of the first exhaust port 103.
After passing through the front section of the first conveyor 130, the grain stillage is cooled and the molecular motion speed is relatively slow. So that the grain stillage on the rear section of the first conveyor 130 releases less water vapor, and a small amount of water vapor flows along with the gas in the first closed pipe 100 toward the second exhaust port 104, and finally is discharged to the outside through the second exhaust port 104.

The aperture of the first air outlet 103 is smaller than that of the second air outlet 104, so that the first air outlet 103 can fully absorb and discharge the water vapor released when the grain stillage falls onto the first conveyor 130. The second exhaust port 104 is capable of sufficiently absorbing and exhausting the water vapor released from the grain in the conveying housing 107.
Referring to fig. 1, in the present embodiment, a scraper is disposed in the feeding housing 106, and the scraper is located on a side of the feeding housing 106 close to the conveying housing 107. The scraper and the first conveyer belt 130 are arranged at intervals, and grain grains are conveyed through an interval space between the scraper and the upper surface of the first conveyer belt 130, so that the thickness of the grain grains is reduced, the grain grains are uniformly covered on the first conveyer belt 130, and the cooling of the grain grains is facilitated.
The feeding shell 106 and the conveying shell 107 extend along the extending direction of the first conveying belt 130, a plurality of observation windows 105 are arranged above the first conveying belt 130 on two side walls of the feeding shell 106 and the conveying shell 107, and the plurality of observation windows 105 are arranged at intervals along the extending direction of the conveying shell 107, so that a worker can observe the cooling process of grain grains through the observation windows 105.

An induced draft fan 141 is disposed at an end of the exhaust hood 140 facing away from the first closed pipeline 100 to exhaust the gas in the first closed pipeline 100 to the outside.
The aperture of the exhaust hood 140 gradually decreases in the bottom-up direction. The induced draft fan 141 is disposed above the exhaust hood 140, so that the flow rate of the gas in the exhaust hood 140 is gradually increased in the bottom-up direction, and the water vapor at the air outlet on the upper side of the exhaust hood 140 is effectively prevented from being liquefied into water.
