Description

Technical Field

[0001] The utility model relates to the field of food brewing, in particular to a grain cooling and koji-making integrated machine and a grain processing system. Background Art

[0002] In the food brewing industry, the main purpose of koji making is to cultivate microorganisms, let them grow and reproduce fully on the koji material, secrete a large number of various enzymes, and provide the material basis for the decomposition, transformation and synthesis of raw materials in the fermentation process. Monascus is a microorganism with specific enzyme activity. The growth of Monascus needs to be carried out in a specific environment. In order to improve the growth of koji in grain materials, the grain needs to be soaked, steamed and cooled.

[0003] In the prior art, taking the production process of red yeast rice as an example, the current red yeast rice production generally adopts the method of manually pouring grains into a grain soaking tank, draining the water in the grain soaking tank after a period of time, shoveling out the soaked grains, and spreading the grains into a cooking device for cooking (generally using high-temperature steam for cooking) in a "steam-sensing and steaming" manner, adding water and stirring 1 to 2 times during the period, and after cooking, shoveling out the grains and transferring them to an open space to spread and cool, manually spreading the koji and stirring them evenly, and then collecting them into piles or transferring them to a culture room for fermentation tank cultivation. After the cultivation is completed, the grains are transferred out for drying to finally obtain the product red yeast rice.

[0004] Among them, in the process of cooling the seed koji, it is difficult to control the uniformity of the seed koji by manual spreading, which affects the effect of the seed koji. Utility Model Content

[0005] The utility model aims to provide a grain cooling and koji-growing all-in-one machine and a grain processing system, which can make the distribution of microorganisms in grains uniform and save manpower.

[0006] The first aspect of the utility model provides a grain cooling and koji seeding integrated machine, comprising a chamber, a conveyor belt, an air cooling mechanism and a koji seeding mechanism. The chamber has a grain inlet and a grain outlet at both ends along the length direction of the chamber, the conveyor belt has air holes and is arranged in the chamber along the length direction of the chamber, the conveyor belt transports grain along the conveying direction from the grain inlet to the grain outlet, and along the conveying direction, the conveyor belt is arranged in an upward direction inclined to the horizontal direction. The air cooling mechanism supplies air to the conveyor belt in the form of air holes passing through the conveyor belt, and the koji seeding mechanism is arranged on the side of the air cooling mechanism close to the grain outlet along the conveying direction.

[0007] According to the technical solution of the utility model, after the cooked grains enter the grain inlet of the chamber, the air cooling mechanism blows air toward the grains through the ventilation holes. Since the conveyor belt is arranged in an upward manner inclined to the horizontal direction, it occupies less space and has a larger contact area with the wind blown out by the air cooling mechanism, thereby achieving rapid cooling of the grains. At the same time, the grains are continuously transported to the grain outlet. After the grains are cooled to a suitable temperature, the koji-seeding mechanism on the side of the air cooling mechanism close to the grain outlet automatically spreads koji toward the grains on the conveyor belt. No manual operation is required throughout the process, thus saving human resources. In addition, the koji-seeding mechanism can achieve more uniform koji-seeding, thereby achieving uniform distribution of microorganisms in the grains.

[0008] As a preferred technical solution, the conveyor belt has an inclination angle of 10-30° with respect to the horizontal direction.

[0009] According to the preferred technical solution, when the conveyor belt is inclined at an angle of 10-30° to the horizontal direction, it can prevent the grain from falling off the conveyor belt while allowing the excess liquid yeast to penetrate into the grain from the high point of the conveyance.

[0010] As a preferred technical solution, the koji-seeding mechanism adds liquid koji to the grain on the conveyor belt.

[0011] According to the preferred technical solution, since the conveyor belt is inclined and the koji-seeding mechanism is on the side closer to the grain outlet, the liquid koji will fall into the unseeded grain as the conveyor belt inclines after being sprayed, thereby ensuring uniform koji-seeding while making full use of the liquid koji.

[0012] As a preferred technical solution, the grain cooling and koji-seeding integrated machine also includes a disperser, which is arranged on the side of the koji-seeding mechanism close to the grain outlet along the conveying direction.

[0013] According to the preferred technical solution, the disperser can further mix the liquid koji and the grains evenly and allow more spaces between the grains, which is more conducive to the growth of microorganisms.

[0014] As a preferred technical solution, the air cooling mechanism supplies air to the grain on the conveyor belt from bottom to top.

[0015] According to this preferred technical solution, since the conveyor belt is inclined, the air supply from bottom to top can further increase the contact area between the air duct and the conveyor belt, thereby improving the cooling effect.

[0016] As a preferred technical solution, the air cooling mechanism includes a fan, an air supply pipeline and an air distribution unit. The air supply pipeline passes through the bottom of the chamber and enters the chamber, and the air distribution unit is arranged at the end of the air supply pipeline and is located below the conveyor belt carrying the grain.

[0017] According to the preferred technical solution, the air supply duct guides the air blown out by the fan into the interior of the chamber, and the air distribution unit can blow the air blown out by the fan evenly toward the conveyor belt, covering a larger area, and allowing the food on the conveyor belt to be cooled evenly and quickly.

[0018] As a preferred technical solution, the air cooling mechanism has multiple groups and is arranged in sequence along the conveying direction.

[0019] According to this preferred technical solution, by setting up multiple groups of air cooling mechanisms, a larger range can be covered along the conveying direction of the conveyor belt, thereby improving the cooling effect.

[0020] The second aspect of the utility model provides a continuous grain processing system, which has the grain cooling and koji-producing integrated machine of the first aspect of the utility model.

[0021] As a preferred technical solution, the continuous grain processing system also includes a grain steaming device and a disc koji making machine. The grain steaming device is arranged at the front stage of the grain cooling and koji seeding machine, and supplies the steamed grain to the grain inlet of the grain cooling and koji seeding machine. The disc koji making machine is arranged at the rear stage of the grain cooling and koji seeding machine, and the grain sent out from the grain outlet of the grain cooling and koji seeding machine is supplied to the disc koji making machine.

[0022] According to the preferred technical solution, a grain steaming device is arranged at the front stage of the grain cooling and koji-growing machine, and a disc koji-making machine is arranged at the rear stage of the grain cooling and koji-growing machine. The grain can be steamed in the grain steaming device, and the steamed grain is sent to the grain cooling and koji-growing machine for cooling and growing koji, and finally sent to the disc koji-making machine for cultivation. The whole process can be carried out continuously and automatically by the device without manual labor, which saves manpower and can improve the efficiency of koji-growing operation.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to reduce labor costs and make the density of microorganisms in the grain more uniform, this embodiment provides a grain cooling and koji seeding all-in-one machine 100. Figure 1 1 is a schematic diagram of the overall structure of a grain cooling and yeast-growing integrated machine 100 provided in an embodiment of the present utility model. Figure 1 As shown, the grain cooling and koji-seeding machine 100 includes a chamber 1, a conveyor belt 2, an air cooling mechanism 3 and a koji-seeding mechanism 4.

[0029] The chamber 1 is used to store food. The external structure of the chamber 1 is not limited here. It is only limited that the inner surface of the chamber 1 forms a hollow food channel, which is arranged along the length direction of the chamber 1, and the two ends of the food channel are opened as a food inlet 11 and a food outlet 12. After the cooked food is sent into the chamber 1 through the food inlet 11 of the chamber 1, it is cooled in the chamber 1 and transported to the food outlet 12 to be discharged from the chamber 1.

[0030] The conveyor belt 2 is arranged in the chamber 1 along the length direction of the chamber 1. The grains entering the chamber 1 from the grain inlet 11 fall on the surface of the conveyor belt 2 and are transported to the grain outlet 12 by the conveyor belt 2. The conveyor belt 2 is provided with ventilation holes 21. The ventilation holes 21 can be through holes opened on the conveyor belt 2. Preferably, the through holes can be covered with a wire mesh to maintain the ventilation properties of the through holes. In particular, in the grain cooling and koji-producing integrated machine 100 provided in this embodiment, the setting direction of the conveyor belt 2 is inclined upward to the horizontal direction, that is, the end of the conveyor belt 2 close to the grain inlet 11 is lower than the end of the conveyor belt 2 close to the grain outlet 12. The inclined conveyor belt 2 can reduce the floor space of the device while ensuring the cooling time.

[0031] One or more groups of air cooling mechanisms 3 supply air to the conveyor belt 2 in the form of air flow passing through the air holes 21 of the conveyor belt 2. Through the cooperation between the air cooling mechanism 3 and the air holes 21 of the conveyor belt 2, the wind speed and the uniformity of air flow distribution can be increased, the air cooling efficiency can be improved, and the grain can be quickly cooled to a temperature suitable for seeding during continuous transportation. In some preferred embodiments, the air cooling mechanism 3 may include a fan 31, an air supply pipeline 32, and an air distribution unit 33, wherein the air supply pipeline 32 is connected to the fan 31, and the air supply pipeline 32 guides the air blown by the fan 31 to the inside of the chamber 1, and the air distribution unit 33 is arranged at the end of the air supply pipeline 32 and is connected to the air supply pipeline 32. The air distribution unit 33 is arranged below the conveyor belt 2 carrying the grain toward or through the air holes 21, and the air blown by the fan 31 can be evenly blown to the conveyor belt 2 through the air distribution unit 33 to cover a larger area, so that the grain on the conveyor belt 2 is evenly and quickly cooled. Among them, the air duct of the air distribution unit 33 can be perpendicular to the conveyor belt 2, or can be set along the direction of gravity (the air cooling mechanism 3 supplies air to the grain on the conveyor belt 2 from bottom to top, or the air cooling mechanism 3 supplies air to the grain on the conveyor belt 2 from top to bottom).

[0032] The koji seeding mechanism 4 is arranged on one side of the air cooling mechanism 3 close to the grain outlet 12 along the conveying direction. The structure of the koji seeding mechanism 4 is not limited here. For example, Figure 1 The structure of a preferred koji-seeding mechanism 4 is shown in the figure, and the koji-seeding mechanism 4 includes a nozzle, which realizes koji-seeding by spraying liquid koji or koji powder toward the conveyor belt 2, or in other embodiments, the koji-seeding mechanism 4 can also be a dropper, which continuously produces liquid carrying microorganisms (such as Monascus) on the surface of the conveyor belt 2. Preferably, liquid koji is stored in the koji-seeding mechanism 4. Since the conveyor belt 2 is tilted and the koji-seeding mechanism 4 is on the side closer to the grain outlet 12, the liquid koji will diffuse downward into the grain that has not been seeded with koji due to the tilt of the conveyor belt 2 after spraying, so that the liquid koji can be fully utilized while ensuring uniform koji-seeding. Furthermore, the liquid koji stored in the koji-seeding mechanism 4 also contains nutrient solution components, which are more conducive to the growth of microorganisms and improve the cultivation effect of koji-seeding.

[0033] In this embodiment, the conveyor belt 2 is arranged in an upward manner inclined relative to the horizontal direction, and the koji-seeding mechanism 4 is arranged on the side of the air cooling mechanism 3 close to the grain outlet 12. After the cooked grain enters the grain inlet 11 of the chamber 1, the air cooling mechanism 3 blows air to the grain through the air holes 21, and the grain is continuously transported to the grain outlet 12 while being rapidly cooled. After the grain is cooled to a suitable temperature, the koji-seeding mechanism 4 automatically spreads koji onto the grain on the conveyor belt 2. No manual operation is required throughout the process, thus saving human resources. In addition, the koji-seeding mechanism 4 can achieve more uniform koji-seeding, so that the distribution of microorganisms in the grain is uniform.

[0034] In addition, in order to prevent the grain from falling off the conveyor belt 2, the inclination angle of the conveyor belt 2 should not be too large in consideration of the adhesion of the grain to the conveyor belt 2. Moreover, in order to allow the excess liquid to penetrate into the grain from the high point of the conveyor, the conveyor belt 2 is inclined at an angle of 10-30° to the horizontal direction in consideration of the floor space of the device.

[0035] In some preferred embodiments, the grain cooling and koji seeding machine 100 further has a dispersing machine (not shown in the figure), which is arranged on the side of the koji seeding mechanism 4 close to the grain outlet 12 along the conveying direction. The dispersing machine can further mix the liquid koji and the grain evenly, and make the grain directly have more gaps, which is more conducive to the growth of microorganisms.

[0036] In other preferred embodiments, the grain cooling and koji seeding machine 100 may also have a temperature detection device 5, which is arranged between the air cooling mechanism 3 and the koji seeding mechanism 4, and is used to detect the temperature of the grain on the conveyor belt 2. Further preferably, the air cooling mechanism 3 is electrically connected to the temperature detection device 5, so that the air volume of the air cooling mechanism 3 can be controlled according to the detection result of the temperature detection device 5 to ensure that the cooling temperature of the grain is more suitable for the reproduction of microorganisms.

Figure 1 and Figure 2 In other embodiments of the present application, a continuous grain processing system is also provided, which has the grain cooling and koji-producing all-in-one machine 100 provided in this embodiment.

[0038] The grain continuous processing system may further include a grain steaming device 6 and a disc koji making machine 7. The grain steaming device 6 is arranged at the front stage of the grain cooling and koji-seeding integrated machine 100, and supplies steamed grain to the grain inlet 11 of the grain cooling and koji-seeding integrated machine 100. The disc koji-making machine 7 is arranged at the rear stage of the grain cooling and koji-seeding integrated machine 100, and the grain sent from the grain outlet 12 of the grain cooling and koji-seeding integrated machine 100 is supplied to the disc koji-making machine 7.

[0039] In this embodiment, a grain steaming device 6 is provided at the front stage of the grain cooling and koji-growing machine 100, and a disc koji-making machine 7 is provided at the rear stage of the grain cooling and koji-growing machine 100. The grain can be steamed in the grain steaming device 6, and the steamed grain is sent to the grain cooling and koji-growing machine 100 for cooling and growing the koji, and finally sent to the disc koji-making machine 7 for cultivation. The whole process can be carried out continuously and automatically by the device without manual labor, which saves manpower and can improve the efficiency of the koji-growing operation.
