[0002] During the brewing process of liquor, the grains need to be steamed and then spread out to dry and mixed with koji. After steaming, the grains are called fermented grains. After steaming, the fermented grains are spread evenly in the drying hall and spread out to dry, and turned into rows. During the feeding period, a proper amount of water can be sprinkled in before spreading out to dry, and the grains can be turned evenly to cool better and faster. When the temperature of the fermented grains drops to about 30℃, a proper amount of koji is added, and then turned and mixed evenly, and gathered into a pile for the next fermentation process.

[0003] The automated brewing equipment uses a plate chain conveyor for cooling. The plate chain conveyor cooling machine includes a plate chain mechanism and a turning and stirring mechanism. The mash is discharged onto the plate chain, and the plate chain moves forward at the same time. Tracks and turning and stirring mechanisms are provided on both sides of the plate chain. The turning and stirring mechanisms reciprocate on the plate chain to turn the mash and spread it for cooling. The turning and stirring mechanisms can be loaded with koji powder and tail wine. When the temperature is appropriate, the turning and stirring mechanisms can mix the koji and tail wine into the mash. The mash is collected at the end of the plate chain mechanism and enters the next process.

[0024] The technical scheme of the present invention is clearly and completely described below in conjunction with the specific embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] Example 1 like Figure 1-3 A fermented grain cooling machine comprises a frame 3, a conveyor belt 1 and a turning and mixing vehicle 2. The frame 3 is provided with a track so that the turning and mixing vehicle 2 can travel on the conveyor belt 1. After the grain for brewing is steamed, it becomes fermented grain and is discharged onto the conveyor belt 1. The turning and mixing vehicle 2 is started to move back and forth on the conveyor belt 1, and the fermented grain can be turned and spread out to facilitate cooling.

[0026] The front side or / and rear side of the mixer truck 2 is provided with a blowing device 21, and the lower side of the mixer truck 2 is provided with a stem turning device 24 and a stem pulling device 23; the blowing device 21 is connected to compressed air through the air pipe 5, and the blowing device 21 blows air toward the surface of the conveyor belt 1; the blowing device 21 is provided with a slit-shaped air outlet. The stem pulling device 23 is provided with a roller shaft 230, and a plurality of stem pulling blades 231 are provided on the roller shaft 230. The roller shaft 230 and the stem pulling blades 231 are hollow structures and are connected internally. The roller shaft 230 is connected to compressed air through the air pipe 5, and an air outlet is provided at the front end of the stem pulling blade 231. The air pipe 5 is connected to the air compressor 4, and the air intake of the air compressor 4 needs to be dusted and dried, and no excess dust and moisture can be present. Before starting the mixer truck 2, the blowing device 21 and the stem pulling device 23 are connected and tied using an air pipe. When the mixing truck 2 is started, the blowing device 21 blows pressurized air onto the mash on the conveyor belt 1. The air outlet width of the blowing device 21 is as wide as the working surface of the conveyor belt, so that it can cool the mash evenly. The roller 230 and the stem removing blade 231 are connected by welding. When the mixing truck 2 moves, the stem removing blades 231 arranged at intervals will stack the mash into a multi-stem shape to increase the heat dissipation area of ​​the mash. The stem removing device 23 is fixed to the lower side of the mixing truck 2 through the roller 230. Figure 4 and 5 The air pipe 5 is connected to the stemming device 23, tied and fixed, to provide pressurized air to the hollow structure inside the roller 230 and the stemming blade 231, and to make the air ejected from the air outlet (gap) at the front end of the stemming blade 231. A filter can be set at the air outlet at the front end of the stemming blade 231 to prevent the mash from entering.

[0027] The front end of the stemming blade 231 is provided with an air outlet, so that the stemming blade 231 can directly dissipate heat in the fermented mash when turning the stems. The cold air discharged from the front end of the stemming blade 231 directly acts on the high temperature area inside the fermented mash, and the cooling effect is enhanced compared to blowing air on the surface of the fermented mash.

[0028] When the high-temperature mash on the conveyor belt 1 is cooled by the blowing device 21 and the stemming device 23, the steam will quickly spread and cover the conveyor belt 1, causing the conveyor belt 1 and the indoor temperature to rise. Therefore, the air inlet of the air compressor 4 that provides cold air needs to be set outdoors to ensure that the temperature of the cold air does not continue to rise. Compared with the design of directly setting a cooling fan on the mixing truck 2, the cooling effect of the mash can be improved. Even if the production is long-term and the indoor temperature rises significantly, it will not affect the cooling of the mash.

[0029] The mixing truck 2 is provided with a hopper 20 for loading koji and a liquid storage tank. The hopper 20 is provided with a koji valve and a liquid storage tank valve. The liquid storage tank is filled with cold water in advance, and some tail wine can be added to the cold water. The koji in the hopper 20 can fall onto the mash on the conveyor belt 1 through the koji valve. The cold water in the liquid storage tank can drip directly onto the mash on the conveyor belt 1 through the liquid storage tank valve. An appropriate amount of cold water helps to cool the mash and can also replenish the lost water.

[0030] When the cooling temperature of the mash drops to about 30°C, the koji valve of the hopper 20 is controlled to open, and the koji can be mixed in while the mash is being stirred to complete the koji mixing operation.

[0031] The fermented mash cooling machine uses compressed air as the air source of the blowing device, which is lower in temperature than the air source on the cooling machine, and the fermented mash cooling machine has a better effect. The stemming device is also connected to compressed air, so that the stemming blade provides cold air to cool the fermented mash when it contacts it. The cold air directly cools the inside of the fermented mash pile, and the cooling speed is significantly improved, which greatly improves the efficiency of the cooling link in automated wine production.

[0032] The lower side of the mixer truck 2 is also provided with a stem turning device 24 and a wheel 22. The blowing device 21 is a hollow structure, and a pointed blowing port is provided at the lower side. The blowing port of the blowing device 21 is set from one side of the conveyor belt 1 to the other side. The side of the stem removing blade 231 connected to the roller shaft 230 is thicker, and the air outlet at the front end of the stem removing blade 231 is thinner.

[0033] The stem turning device 24 and the stem lifting device 23 are both provided with two groups, and the stem lifting device 23 is arranged on the outside of the stem turning device 24. The stem turning device 24 is provided with stem turning blades, and the stem turning device 24 is provided with a motor to rotate the stem turning blades. The stem turning device 24 can be used to break up the fermented grains after the stems are lifted, so as to achieve the effect of turning and stirring. The shape of the stem turning device 24 can be designed as a roller with blades. It can also be made in a flat plate shape to flatten the fermented grains after the stems are lifted, and it can also be made with reference to the shape of the stem turning designed in the prior art. The wheels 22 should cooperate with the tracks set on both sides of the conveyor belt 1 on the frame 3 to make the mixing truck 2 run smoothly, and the wheels 22 can be driven by a motor.

[0034] Example 2 like Figure 6 The stem turning device 24 can also be set as a spiral blade, and the spiral direction of the spiral blade is set symmetrically, and the spiral blade can be used to push the center of the mash to both sides. When the mash is discharged to the conveyor belt, it is a pile with a high middle and low sides, which helps to flatten the mash. The stem turning device 24 is set at a certain height from the conveyor belt 1, which can push the mash in the center of the pile to both sides and prevent excessive pushing.

[0035] In this embodiment, the valve of the liquid storage tank provided on the hopper 20 is connected to the roller shaft 230 of the stem removing device 23, and cold water is discharged from the liquid storage tank into the roller shaft 230, and then blown out from the air outlet of the stem removing blade 231 with the wind. The upper end of the liquid storage tank needs to be connected to a bound air pipe to increase the internal pressure of the liquid storage tank for easy drainage. All air pipes are connected to an air compressor. Adjust the pressure of the air compressor outlet pipe to ensure that the stem removing blade 231 cannot blow the mash away.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
