Description

Technical Field

[0001] The utility model relates to the field of food brewing, in particular to a continuous 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 soaking and steaming grain, a large amount of water needs to be introduced into the grain soaking tank and the grain steaming container, and the soaking water and the grain steaming water are discharged as wastewater after use, which will cause a large waste of water resources.

[0005] The utility model aims to provide a continuous grain processing system, which can save water resources in the grain soaking and steaming processes of grain processing.

[0006] The utility model provides a continuous grain processing system, which comprises a grain soaking tank and grain steaming equipment.

[0007] The grain soaking tank has a material outlet, a grain inlet and a water inlet. The grain enters the grain soaking tank from the grain inlet, is soaked in water entering through the water inlet, and is discharged from the material outlet.

[0008] The grain steaming device comprises: a chamber, a conveying mechanism and a steam supply device, wherein the chamber is an airtight chamber capable of sealing steam in the chamber, the conveying mechanism is configured to convey grain from a first end to a second end of the chamber, and the steam supply device is connected to the chamber to supply water vapor into the chamber. In particular, the chamber has a steam outlet, which is connected to a water inlet of a grain soaking tank.

[0009] According to the technical solution of the utility model, after the grain and water are mixed and soaked in the grain soaking tank, the material obtained after soaking is discharged from the material outlet to the grain steaming equipment. At the same time, the steam supplied by the steam supply device contacts the material being transported in the chamber and heats the material at high temperature to cook the material. After the steam of the cooked material is cooled, the water generated is passed from the steam outlet to the water inlet of the grain soaking tank, thereby realizing the repeated recycling of water between the grain steaming equipment and the grain soaking tank in the grain continuous processing system, saving water resources.

[0010] As a preferred technical solution, the continuous grain processing system also includes: a condensing heat exchanger arranged on the connecting pipeline between the steam outlet and the water inlet.

[0011] According to the preferred technical solution, the condensing heat exchanger is arranged on the connecting pipeline between the steam outlet and the water inlet, so that the mixed fluid of steam and water flowing out of the cooking equipment is firstly heat-exchanged through the condensing heat exchanger, and the water after heat exchange then enters the grain soaking tank through the water inlet. On the one hand, it can accelerate the condensation of steam and increase the amount of condensed water circulating in the grain soaking tank; on the other hand, it can also utilize the waste heat of the used steam to improve the energy utilization efficiency of the continuous grain processing system.

[0012] As a preferred technical solution, the steam outlet is arranged at the second end of the chamber.

[0013] According to the preferred technical solution, since the conveying mechanism conveys the material from the first end to the second end, the steam will slowly cool down and flow to the second end as the material is conveyed. Setting the steam outlet at the second end of the chamber is more conducive to collecting steam cooling water.

[0014] As a preferred technical solution, the chamber has a steam inlet, and the steam supply device is connected to the chamber via the steam inlet.

[0015] According to this preferred technical solution, by setting the steam inlet, the discharge direction of the steam introduced into the chamber by the steam supply device can be controlled, for example, it can be supplied directly toward the material, thereby improving the steam cooking efficiency of the material.

[0016] As a preferred technical solution, the steam inlet has one or more steam inlets extending or distributed in the conveying direction of the conveying mechanism.

[0017] According to the preferred technical solution, by extending a steam inlet in the conveying direction of the conveying mechanism, or distributing multiple steam inlets in the conveying direction, the material can be continuously in contact with the high-temperature steam introduced into the steam inlet during the conveying process, so that the cooking and heating of the material is more uniform, which is beneficial to the subsequent brewing.

[0018] As a preferred technical solution, in the conveying direction of the conveying mechanism, the steam inlet is disposed in the chamber at a position between the first end and the second end and closer to the first end.

[0019] According to this preferred technical solution, the steam inlet is located between the first end and the second end of the chamber and closer to the first end, so that it can contact the material entering the chamber more quickly and accelerate the cooking rate of the material in the chamber.

[0020] As a preferred technical solution, the continuous grain processing system also includes a grain soaking water recovery tank, there are multiple grain soaking tanks, and the grain soaking water outlets of the multiple grain soaking tanks are all connected to the inlet of the grain soaking water recovery tank.

[0021] As a preferred technical solution, through the recycling of the grain soaking water recovery tank, multiple grain soaking tanks can take turns to soak the grain, thereby improving the efficiency of the grain soaking operation and reducing the waste of water resources.

[0022] According to this preferred technical solution, the material outlets of the multiple grain soaking tanks are all connected to the first end of the chamber, and multiple first valves are respectively provided in the pipelines connecting the multiple material outlets and the chamber.

[0023] According to the preferred technical solution, the material output of multiple grain soaking tanks can be controlled by controlling the first valve, thereby realizing cross-soaking of grain in multiple grain soaking tanks. The flow rate of the material output from the grain soaking tanks can be reasonably planned by controlling the opening and closing of multiple valves.

[0024] As a preferred technical solution, multiple valves are opened in sequence to asynchronously supply food from multiple food soaking tanks to the chamber.

[0025] According to this preferred technical solution, by sequentially controlling a plurality of valves, it is possible to maintain continuous input of materials into the grain steaming equipment while improving the efficiency of the grain soaking operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] 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.

[0036] In order to save water resources for soaking and steaming grains, this embodiment provides a continuous grain processing system. Figure 1 This is a schematic diagram of the overall structure of a continuous grain processing system provided by the present utility model. Figure 1 As shown, the continuous grain processing system includes a grain soaking tank 1 and a grain steaming device 2.

[0037] Among them, the grain soaking tank 1 can be a container with a cavity for accommodating water and grain. A material outlet 11, a grain inlet 12 and a water inlet 13 are provided on the wall of the grain soaking tank 1. The grain enters the grain soaking tank 1 from the grain inlet 12, and the water enters the grain soaking tank 1 from the water inlet 13. After soaking in the grain soaking tank 1 for a period of time, the grain enters the grain soaking tank 1 from the grain inlet 12, and after soaking in the water entering through the water inlet 13, the soaked water and material (soaked grain) are discharged from the material outlet 11, and after filtering, the material enters the grain steaming equipment 2, and the water is discharged.

[0038] The grain steaming equipment 2 has a chamber 21, a conveying mechanism 22 and a steam supply device 23. The chamber 21 can be an airtight chamber 21 that seals steam in the chamber 21. After the material enters the airtight chamber 21 from the material inlet of the grain steaming equipment 2, it is continuously steamed under the action of the high-temperature steam in the chamber 21.

[0039] The conveying mechanism 22 can be any conveying structure that can convey wet materials, such as a conveyor belt, a conveying auger, etc., without limitation. The conveying mechanism 22 can convey the grain from the first end 211 of the chamber 21 to the second end 212, so that the grain can be conveyed while being steamed at high temperature in the chamber 21.

[0040] The steam supply device 23 is in communication with the chamber 21. The steam supply device 23 can generate a large amount of high-temperature steam, and can be, for example, a steam generator. The high-temperature steam generated by the steam supply device 23 is passed into the chamber 21 via the steam inlet 24 of the chamber 21. Preferably, the steam inlet 24 has one or more extending or distributed in the conveying direction of the conveying mechanism 22. By extending the steam inlet 24 in the conveying direction of the conveying mechanism 22, or distributing multiple steam inlets 24 in the conveying direction, the material can be continuously in contact with the high-temperature steam introduced by the steam inlet 24 during the conveying process, so that the steaming and heating of the material is more uniform, which is beneficial to the subsequent brewing.

[0041] Among them, the steam inlet 24 can be opened at any position on the wall of the chamber 21. Generally speaking, a position where steam can be sprayed directly toward the material is more preferred. In some preferred embodiments, in the conveying direction of the conveying mechanism 22, the steam inlet 24 is set in the chamber 21. The position is located between the first end 211 and the second end 212, closer to the first end 211, so that it can contact the material entering the chamber 21 more quickly, thereby accelerating the cooking rate of the material in the chamber 21.

[0042] Furthermore, the conveying mechanism 22 is a conveying auger, and one or more steam inlets 24 are extended or distributed in the conveying direction of the conveying mechanism 22. The material can be continuously broken up through the conveying of the conveying auger. At the same time, the one or more steam inlets 24 extending or distributed in the conveying direction can be used to heat the steamed material more evenly.

[0043] Particularly, in the present embodiment, the chamber 21 of the steam supply device 23 has a steam outlet 25 , and the steam outlet 25 is communicated with the water inlet 13 of the grain soaking tank 1 .

[0044] Specifically, according to the continuous grain processing system provided by the present embodiment, it is only necessary to pass the grain into the grain soaking tank 1 from the grain inlet 12, and to pass water into the grain soaking tank 1 from the water inlet 13. After the grain and water are mixed and soaked in the grain soaking tank 1, the material obtained after soaking the grain is discharged from the material outlet 11 to the grain steaming equipment 2. The material enters the chamber 21 of the grain steaming equipment 2 from the first end 211, and is slowly conveyed to the second end 212 under the drive of the conveying mechanism 22. At the same time, the steam supplied by the steam supply device 23 enters the chamber 21 from the steam inlet 24, contacts the material being conveyed and heats the material at high temperature, so that the material conveyed to the second end 212 is the material that has been steamed. Finally, the steam is discharged from the steam outlet 25 and cooled, and the hot water generated after cooling is passed into the water inlet 13 of the grain soaking tank 1, thereby realizing the repeated recycling of water between the grain steaming equipment 2 and the grain soaking tank 1 in the continuous grain processing system, thereby saving water resources.

[0045] Figure 2 A preferred continuous grain processing system provided by the present utility model is shown in FIG. Figure 2 As shown, preferably, the steam outlet 25 is disposed at the second end 212 of the chamber 21. Since the cooked material is transported to the second end 212, the steam will also slowly cool down and flow to the second end 212 along with the transportation of the material. Disposing the steam outlet 25 at the second end 212 of the chamber 21 is more conducive to collecting steam cooling water.

[0046] Further preferably, the continuous grain processing system also has a condensing heat exchanger 3, which is arranged on the connecting pipeline between the steam outlet 25 and the water inlet 13, so that the mixed fluid of steam and water flowing out of the steam outlet 25 of the cooking equipment is first heat-exchanged by the condensing heat exchanger 3 and then converted into hot water. Preferably, the hot water can also be passed into a hot water tank (not shown in the figure), and the hot water in the hot water tank is used for other production process water in the workshop, thereby realizing the recovery and utilization of thermal energy and saving energy consumption. The water after heat exchange enters the grain soaking tank 1 through the water inlet 13.

[0047] Through the above method, on the one hand, the condensation of steam can be accelerated and the amount of condensed water circulating in the grain soaking tank 1 can be increased; on the other hand, the waste heat of the used steam can be utilized to improve the energy utilization efficiency of the continuous grain processing system.

[0048] Figure 3 Another preferred continuous grain processing system provided by the present utility model is shown in FIG. Figure 3 As shown, in some preferred embodiments, the continuous grain processing system also includes a grain soaking water recovery tank 5, there are multiple grain soaking tanks 1, and the grain soaking water outlets of the multiple grain soaking tanks 1 are connected to the inlet of the grain soaking water recovery tank 5, and the water in the grain soaking water recovery tank 5 is used for soaking the next batch of grain soaking tanks 1 and flushing the grain in the grain soaking tanks 1 to the inlet of the grain steaming equipment 2, thereby realizing the repeated recycling of water in the grain soaking process in the grain processing system and saving water resources.

[0049] The specific number of grain soaking tanks 1 is not limited. Here, two grain soaking tanks 1 (grain soaking tank 1A and grain soaking tank 1B) are taken as an example for explanation. Grain soaking tank 1A and grain soaking tank 1B can soak grain in turn, thereby improving the efficiency of grain soaking operation.

[0050] Preferably, the material outlets 11 of the grain soaking tank 1A and the grain soaking tank 1B are both connected to the first end 211 of the chamber 21, and a plurality of first valves 4 are respectively provided in the pipelines connecting the plurality of material outlets 11 and the chamber 21. By controlling the first valves 4, the material output of the plurality of grain soaking tanks 1 can be controlled, so that the grain soaking of the plurality of grain soaking tanks 1 is cross-wise realized, and the flow of the material output from the grain soaking tank 1A and the grain soaking tank 1B can be reasonably planned by controlling the opening and closing of the plurality of valves.

[0051] Further preferably, the plurality of valves are opened sequentially and successively to asynchronously supply grain from the grain soaking tank 1A and the grain soaking tank 1B to the chamber 21. By sequentially controlling the plurality of valves, the continuous input of materials in the grain steaming device 2 can be maintained while improving the efficiency of the grain soaking operation.

[0052] Those skilled in the art will appreciate that, in the above-mentioned embodiments, many technical details are provided in order to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the above-mentioned embodiments, the technical solutions claimed for protection by the claims of the present application can be basically realized. Therefore, in practical applications, various changes can be made to the above-mentioned embodiments in form and detail without departing from the spirit and scope of the present utility model.
