Description

Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to a mobile fermentation pit. Background Technology

[0002] Baijiu (white liquor) has a long history in my country and is one of the major traditional liquor types. Currently, baijiu is generally brewed from red sorghum. The traditional brewing process is as follows: soaking the grain → steaming the grain → cooling → adding yeast → collecting and cultivating microorganisms → blending the mash → fermenting in the cellar → sealing the cellar → removing from the cellar → distillation. Among these, the most complex and crucial process is the cellar fermentation. In the production of strong-aroma baijiu, the cellar mud is fundamental, playing a vital role in the formation of aroma and flavor compounds. Therefore, in both traditional and modern mechanized and automated strong-aroma baijiu production, ensuring sufficient contact between the yeast and the cellar mud, allowing the aroma and flavor compounds produced by the functional microorganisms in the mud to accumulate in the yeast, thereby improving the quality of the yeast and laying the foundation for the subsequent quality assessment of the distilled liquor, is a crucial technological measure for improving the quality of strong-aroma baijiu. The fermentation containers are generally traditional earthenware jars and cement pools. For mass production, cement pools, constructed by digging pits in the ground and then pouring cement, are more commonly used. Traditional brewing methods typically involve manual labor. After the fermentation pit is opened, the yellow liquid is manually removed to separate the mash from the liquid. Common brewing methods have the following drawbacks in the process from fermentation in the pit to opening:

[0003] (1) The fermentation pit is deep, and manual labor is required to enter the fermentation pit to dig out the yeast. However, since the structure of the fermentation pit is an upward-opening structure, it is not possible to completely remove the yeast with the help of large equipment such as grab buckets. In the end, manual labor is still required to dig it out and clean it.

[0004] (2) The fermentation pit is a cement pool that is dug in the ground and then poured with cement. It cannot be moved. This results in the fermentation pit itself occupying a large area. At the same time, a lot of manpower is needed to transfer the yeast or to use large equipment for operation during subsequent processing. This makes the interval between each fermentation pit wide enough to allow large equipment to enter, which makes the transfer of yeast very inconvenient.

[0005] (3) The yellow water seepage in the cellar will pollute the environment and require additional manpower and resources to clean it up. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a movable pit, which facilitates the transfer of the pit, eliminating the need for additional equipment to assist in opening the pit; instead, the pit is moved to the opening station to complete the opening process.

[0007] According to a first aspect of the present invention, a movable fermentation pit includes a bottom plate, three fixed surrounding plates, a detachable baffle, and pit mud. The detachable baffle includes multiple detachable surrounding plates connected sequentially from top to bottom. The bottom plate, the three fixed surrounding plates, and the multiple detachable surrounding plates enclose a fermentation space for yeast fermentation. A fixing component for fixing the pit mud is connected to the inner wall of the fermentation space. The pit mud is attached to the inner wall of the fermentation space. The fixing component is embedded in the pit mud. A yellow water discharge port is provided on the bottom plate.

[0008] The movable fermentation pit according to the present invention has at least the following beneficial effects: Through the above design, the pit mud can be firmly attached to the inner wall of the fermentation space of the pit. Since the entire pit is not a fixed pit formed by digging a pit and pouring cement, it is not necessary to use equipment to assist in opening the pit next to the cement pit, nor is it necessary for workers to enter the fixed cement pit to take the koji. Instead, the movable pit is transported to the koji taking station for koji taking. During the transportation process, it is not easy for the pit mud to fall off due to impact. At the same time, it can be used as the basis for subsequent automated supporting design and production. Compared with the traditional immovable pit, it can greatly reduce the design difficulty.

[0009] According to some embodiments of the present invention, the fixing component includes a plurality of horizontally arranged horizontal support frames, which are evenly spaced and connected to the inner wall of the fermentation space.

[0010] According to some embodiments of the present invention, the horizontal support frame includes a first support plate and a second support plate connected to each other. The first support plate is connected to the inner wall of the fermentation space, and the second support plate has a gap with the inner wall of the fermentation space for filling with pit mud.

[0011] According to some embodiments of the present invention, the fixing component further includes a plurality of longitudinal anti-slip supports connected to the inner wall of the fermentation space. The longitudinal anti-slip supports are arranged perpendicularly to the horizontal support frame, and the longitudinal anti-slip supports are connected between two adjacent horizontal support frames at the same horizontal height.

[0012] According to some embodiments of the present invention, the fixing component further includes a plurality of anchors connected to the inner wall of the fermentation space, the anchors being connected between two adjacent horizontal support frames along the length direction of the longitudinal anti-slip support.

[0013] According to some embodiments of the present invention, the anchor includes an anchor rod, one end of which is connected to the inner wall of the fermentation space, and the other end of which is connected to a plurality of anchor claws.

[0014] According to some embodiments of the present invention, the fixing component further includes a plurality of anti-compression support frames connected to the inner wall of the bottom of the fermentation space.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] refer to Figure 1 , Figure 2 as well as Figure 3 As shown, the movable fermentation pit according to an embodiment of the present invention includes a bottom plate 110, three fixed surrounding plates 120, a detachable baffle 130, and fermentation mud 140. The detachable baffle 130 includes multiple detachable surrounding plates connected sequentially from top to bottom. The bottom plate 110, the three fixed surrounding plates 120, and the multiple detachable surrounding plates enclose a fermentation space 150 for yeast fermentation. A fixing component for fixing the fermentation mud 140 is connected to the inner wall of the fermentation space 150. The fermentation mud 140 is attached to the inner wall of the fermentation space 150. The fixing component is embedded in the fermentation mud 140. A yellow water discharge port 111 is provided on the bottom plate 110.

[0028] In practical use, the fixed components ensure that the mud 140 is firmly attached to the inner wall of the fermentation space 150 of the pit. Since the entire pit is not a fixed pit formed by digging a pit and pouring cement, there is no need to use equipment to assist in opening the pit next to the cement pit, nor is it necessary for workers to enter the fixed cement pit to collect the koji. Instead, the koji is collected by transporting the movable pit to the koji collection station. During the transportation process, it is not easy for the mud 140 to fall off due to impact. At the same time, this can serve as the basis for subsequent automated supporting design and production. For example, the movable pit can be placed on the conveyor track in the production line, or for small-scale production, pulleys can be added to the bottom of the movable pit to facilitate transportation. Compared with traditional immovable pits, this greatly reduces the design difficulty. Due to its significant mobility compared to the fixed cement pit, the movable pit can be moved to a dedicated yellow water discharge station, and the yellow water discharge outlet 111 can be opened to achieve centralized discharge of yellow water.

[0029] It should be noted that the transmission track 300 and pulleys are commonly used technologies in the prior art, and their specific structures and principles will not be elaborated here. In fact, the movement of the movable pit is not fixed, and it has significant mobility compared to the fixed cement pit pit.

[0030] For specific examples, when there are three detachable panels, the detachable panels, from top to bottom, are the Chenqu indicator panel, the Erqu indicator panel, and the Touqu indicator panel. When there are at least three detachable panels, the corresponding number of Chenqu indicator panels, Erqu indicator panels, and Touqu indicator panels are set from top to bottom according to actual needs, simply by correspondingly reducing the size of each panel. Small-sized panels facilitate precise operation and prevent excessive drops during retrieval, making them more suitable for retrieval positions at higher locations, while large-sized panels facilitate rapid operation and are more suitable for retrieval positions at lower locations. The detachable panels are stacked sequentially from top to bottom, and both ends of each detachable panel are fixedly connected to the sides of two fixed panels 120. This fixing method can be achieved by having pins on the sides of the fixed panels 120 and corresponding pin holes on the detachable panels, with the pins engaging with the pin shaft holes to secure the panels together. Of course, this application does not limit the fixing method.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the fixing component includes a plurality of horizontally arranged horizontal support frames 210, and the plurality of horizontal support frames 210 are evenly spaced and connected to the inner sidewall of the fermentation space 150.

[0032] Specifically, the horizontal support frame 210 includes a first support plate 211 and a second support plate 212 connected to each other. The first support plate is connected to the inner wall of the fermentation space 150, and the second support plate has a gap between itself and the inner wall of the fermentation space 150 for filling the pit mud 140.

[0033] More specifically, the above design can provide intermittent support points for the pit mud 140, allowing the pit mud 140 to be attached in sections. After the pit mud 140 on the horizontal support frame 210 is attached and fixed, other gaps are filled, thereby avoiding the landslide process during the attachment of the pit mud 140. This also makes the attachment of the pit mud 140 more neat, reducing the correction time and the attachment time of the pit mud 140.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the fixing component further includes a plurality of longitudinal anti-slip supports 220 connected to the inner sidewall of the fermentation space 150, the longitudinal anti-slip supports 220 being arranged perpendicularly to the horizontal support frame 210, and the longitudinal anti-slip supports 220 being connected between two adjacent horizontal support frames 210 at the same horizontal height.

[0035] Specifically, the longitudinal anti-slip bracket 220 is a hollow ear plate structure, i.e., a U-shaped structure. Through the above design, the structural weight is reduced while ensuring the overall structural effect. The longitudinal anti-slip bracket 220 can reduce the lateral slippage of the pit mud 140 during attachment, thereby making it easier to fix the pit mud 140 and reducing the attachment time of the pit mud 140.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: the fixing component further includes a plurality of anchors 230 connected to the inner wall of the fermentation space 150, and the anchors 230 are connected between two adjacent horizontal support frames 210 along the length direction of the longitudinal anti-slip bracket 220.

[0037] Specifically, the anchor 230 includes an anchor rod 231, one end of which is connected to the inner wall of the fermentation space 150, and the other end of which is connected to a plurality of anchor claws 232.

[0038] More specifically, at least two anchor claws 232 are radially connected to the other end of the anchor rod 231. The anchor rod 231 and anchor claws 232 provide more attachment points for the mud 140, thereby reducing the slippage of the mud 140 and the time required for its adhesion.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: the anchor rod 231 is connected to a water outlet pipe (not shown in the figure), the water outlet pipe is connected to a water pipe (not shown in the figure) buried in the fixed enclosure 120 and the detachable baffle 130, the water pipe is connected to an external water supply source, the anchor claw 232 is a nozzle, and the water outlet pipe is connected to the nozzle.

[0040] In actual production and use, water is supplied to the anchor claws 232, which then flow out through the nozzles and soak into the pit mud 140, thereby achieving the curing of the pit mud 140 and reducing manual curing. At the same time, since the anchor claws 232 are set on the inner walls of the fermentation space 150, the water flowing out from each anchor claw 232 cures the entire movable pit around its perimeter, resulting in more thorough curing of the pit mud.

[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: the fixing component further includes a plurality of anti-compression support frames 240 connected to the inner wall of the bottom of the fermentation space 150. Specifically, the anti-compression support frame 240 has a gantry-shaped structure.

[0042] In some specific embodiments of this utility model, it may also have the following additional technical features: the horizontal support frames 210 can also be arranged in the following array: the horizontal support frames 210 at the same horizontal height are evenly spaced, and the horizontal support frames 210 at different heights are staggered, wherein the length of the horizontal support frame 210 is greater than the distance between two adjacent horizontal support frames 210. Correspondingly, the position design of the longitudinal anti-slip bracket 220 and the anchor 230 can be adapted accordingly.

[0043] refer to Figure 4 as well as Figure 5 As shown, the technical solution according to the utility model embodiment is also equipped with a corresponding fermentation pit method, including the following steps:

[0044] S100. Attach the pit mud 140 to the inner wall of the fermentation space 150 of the movable pit until the pit mud 140 is completely fixed to the inner wall of the fermentation space 150. At this time, the movable pit is in an empty state.

[0045] S200. Fill the empty movable fermentation pit with new yeast, and fill it to a height not lower than the highest point of the uppermost detachable enclosure.

[0046] S300: Move the completed mobile fermentation pit onto the transfer track 300 for fermentation;

[0047] S400: During the fermentation process, the movable pit is periodically moved to the yellow water discharge station via the transmission track 300 for yellow water discharge.

[0048] S500: Move the mobile fermentation pit after fermentation to the corresponding work station to remove the yeast, and mark the mobile fermentation pit as empty after the yeast has been completely removed.

[0049] It should be noted that the conveyor track 300 is a commonly used technical means in the prior art, and its specific structure and principle will not be described in detail here. Of course, the conveyor track 300 is suitable for production line operation, while in small-scale manufacturing, pulleys can also be added to the bottom of the base plate 110 for movement. At the same time, the structure of the pulley is also a commonly used technical means in the prior art, and its specific structure and principle will not be described in detail here. In fact, the movement method of the movable pit is not fixed, and it has significant mobility compared to the fixed cement pit pit.

[0050] In step S400, after the red sorghum has undergone various processing steps before being placed in the fermentation pit, it is sealed in a fermentation container and fermented for several days, at which point yellow liquid will seep out. This yellow liquid is the yellow seepage water that leaks from the mash in the baijiu pit to the lower layer. It contains 1%-2% residual starch, 0.3%-0.7% residual sugar, 4%-5% (V / V) alcohol, as well as acetic acid, humic substances, and autolysates of yeast cells. The yellow liquid is quite acidic, with an acidity of about 5 degrees, and also contains some domesticated caproic acid bacteria and precursor substances for baijiu aroma. It is a good material for creating artificial aging pits, promoting the aging of new pits, and improving the quality of the liquor. Generally, factories often collect it and distill it to obtain yellow liquid liquor, which is then fermented back into the final liquor along with the tail liquor. Therefore, it is necessary to collect and discharge the yellow liquid in a unified manner. However, this technical solution facilitates subsequent automated operations and reduces the workload of workers by setting up yellow liquid discharge outlets on the pit and moving the yellow liquid to the discharge station via a conveyor track 300.

[0051] In some specific embodiments of this utility model, it may also have the following additional technical features: Step S500 specifically includes:

[0052] S510. When it is necessary to remove the aged yeast, move the movable cellar on the conveyor track 300 to the aged yeast removal station, remove the detachable panel at the top, tilt the movable cellar, and remove the yeast exposed above the detachable panel in the middle. This is the aged yeast. After the aged yeast is completely removed, the movable cellar returns to its initial state from the tilted state and returns to the conveyor track 300. At this time, the movable cellar is marked as the cellar where the aged yeast has been removed.

[0053] S520. When it is necessary to remove the second koji, move the koji-removed cellar on the conveyor track 300 to the second koji removal station, remove the detachable partition in the middle, tilt the koji-removed cellar, and remove the koji exposed above the detachable partition at the bottom. This is the second koji. After the second koji is completely removed, the koji-removed cellar returns to its initial state from the tilted state and returns to the conveyor track 300. At this time, mark the movable cellar as the koji-removed cellar.

[0054] S530. When it is necessary to remove the first batch of starter culture, move the cellar with the second batch of starter culture removed from the conveyor track 300 to the second batch of starter culture removal station, remove the detachable panel at the bottom, tilt the cellar with the second batch of starter culture removed, and remove the last batch of starter culture at this time. This is the first batch of starter culture. After the first batch of starter culture is completely removed, the cellar with the second batch of starter culture removed is reset from the tilted state to the initial state and returned to the conveyor track 300. At this time, the movable cellar is marked as empty.

[0055] Specifically, the tilt angle of the movable fermentation pit is 0°-6°. Within this tilt angle range, it is convenient to extract the yeast and reduce the amount of work involved in yeast extraction.

[0056] Preferred, Reference Figure 4 as well as Figure 5 As shown, a lifting mechanism connector 500 is connected to the outer surface of the fixed enclosure 120 opposite to the detachable baffle 130 on the movable cellar. The movable cellar is connected to the lifting mechanism body 600 through the lifting mechanism connector 500. Limiting pins 400 are connected to the outer surfaces of the two opposite fixed enclosures 120. When the cellar reaches the corresponding koji-taking station, a corresponding limiting groove plate 700 with a notch is connected to the koji-taking station. The limiting pin 400 enters the limiting groove plate 700 through the notch 710. Then, the lifting mechanism body 600 drives the movable cellar to rotate and tilt to reach a preset angle, and then the koji-taking operation is performed.

[0057] It should be noted that the lifting mechanism body 600 can be a technical solution commonly used in the prior art, such as using a cylinder, hydraulic cylinder, or electric actuator, etc., and there are no restrictions here.

[0058] Specifically, the opening direction of the notch is horizontal. When the limiting pin 400 enters the notch horizontally, the lifting mechanism body 600 lifts the lifting mechanism connector 500. Since the limiting pin 400 restricts the horizontal movement of the movable pit to only horizontal rotation, the lifting mechanism body 600 drives the movable pit to rotate and achieve tilting.

[0059] In some specific embodiments of this utility model, it may also have the following additional technical features: the fermentation pit method for making koji further includes the following steps:

[0060] S600. Fill the empty movable cellar with new yeast, and fill it to the highest point of the detachable partition at the bottom. At this time, the movable cellar is marked as filled with one layer.

[0061] S700. Fill the first layer of the movable pit with the first layer of filling, and fill it to the highest point of the removable partition in the middle. At this time, it is marked as a movable pit with the second layer of filling.

[0062] S800. Fill the two layers of the movable pit into the two-layer filling pit, and fill the pit to the highest point of the uppermost detachable enclosure. At this point, mark the movable pit as having been filled.

[0063] S900, repeat steps S300-S800.

[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
