Description

Technical Field

[0001] The utility model belongs to the technical field of liquor saccharification and fermentation devices, and particularly relates to a liquor saccharification and fermentation tank. Background Art

[0002] The classic Xiaoqu (Fragrant Xiaoqu) liquor brewing process consists of two main fermentation stages: saccharification and fermentation. The saccharification stage involves adding Xiaoqu (Fragrant Xiaoqu) to the steamed grains. This fermentation process, which lasts approximately 20 hours, aims to rapidly promote the growth and reproduction of the microorganisms inoculated into the grains from the Xiaoqu, while also saccharifying some starch. Saccharification is crucial in the Xiaoqu (Fragrant Xiaoqu) liquor brewing process and is the single most important factor influencing product quality and yield.

[0003] Currently, traditional Xiaoqu-flavored liquor fermentation and saccharification often utilizes a saccharification bed. However, these beds have several drawbacks during use, such as difficulty cleaning, temperature control, mechanical failure, and maintenance. In particular, the near-impossibility of regulating the temperature of the mash during saccharification significantly impacts product quality and yield, directly affecting the ability of subsequent fermentation to proceed normally. Those skilled in the art have devised numerous solutions to the challenge of regulating the mash temperature during saccharification. For example, Chinese patent publication CN220745827U discloses a cooling bed for brewing wine, comprising a cooling bed body, a cooling bed frame, a reversible door, and a sieve plate. A humidifying and blowing channel is provided beneath the cooling bed body, and a support frame and insulation device are located beneath the sieve plate. The insulation device comprises a water heating system consisting of a water heating tank, water heating pipes, and a hot water circulation pump. A blower and a humidifier are provided at the air inlet of the humidifying and blowing channel. The overall structure of the cooling bed in this solution is relatively complex, prone to mechanical failure and difficult to repair; when large-scale batch production is required, the equipment layout is also relatively difficult.

[0004] Chinese patent document CN211035859U discloses a saccharification bed comprising a square box with a mattress at the bottom. The mattress comprises an insulation layer and a film. Partitions are provided at the four corners of the square box to separate the four corners and prevent grain from entering the corners. This solution only considers the insulation of the bottom plate and does not consider the ventilation structure. Therefore, the O2 supply during the growth of microorganisms cannot be effectively ensured, and it is not conducive to regulating the temperature of the saccharification mash.

[0005] Chinese patent publication CN206033715U discloses a grain saccharification and fermentation tank, comprising an open-top housing with a double-layer structure. A hollow space is defined between the inner and outer layers, through which heat-insulating water flows. The upper surface of the inner layer is concave, forming a grain storage trough. A lower inlet and upper outlet pipes are provided at one end of the tank to facilitate the flow of heat-insulating water, while an upper exhaust port is located at the other end. This solution lacks ventilation, failing to effectively ensure oxygen supply during microbial growth. Furthermore, each grain saccharification and fermentation tank requires its own heat-insulating water piping system, making it unsuitable for large-scale mass production. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a winemaking saccharification and fermentation tank which is more convenient for temperature control and is conducive to large-scale batch production.

[0008] It is further preferred that: the top edges of the four side baffles are respectively fixed with top cross beams, which are fixed to form a top rectangular frame, the bottom edges of the four side baffles are respectively fixed with bottom cross beams, which are fixed to form a bottom rectangular frame, the four corners of the top rectangular frame and the four corners of the bottom rectangular frame are fixedly connected one by one through columns, and the insulation groove corresponding to the outer side of each side baffle is enclosed by the outer surface of the side baffle, the top cross beam, the bottom cross beam and two columns.

[0009] It is further preferred that the top crossbeam, columns, saccharification tank bottom plate, side baffles, bottom crossbeam and strip support beams are all made of stainless steel and fixed into a whole by welding.

[0010] It is further preferred that the rubber-plastic thermal insulation cotton structural layer is a molded rubber-plastic thermal insulation cotton board, and the molded rubber-plastic thermal insulation cotton board is fixed in the thermal insulation groove by bonding.

The winemaking saccharification and fermentation tank as a whole can be stacked in multiple layers both in use and in idle state, which is more conducive to full utilization of space and convenient and flexible to use.

The outer surface of the side baffles is insulated with a rubber-plastic insulation layer to insulate the surrounding area of ​​the saccharification tank, preventing rapid temperature loss in the mash. This facilitates temperature control and effectively ensures overall saccharification. This rubber-plastic insulation layer is placed within the insulation groove, facilitating fabrication and preventing damage from minor collisions during transport of the fermentation tank.

[0018] The parts in the figure are marked as: top crossbeam 1, column 2, saccharification tank bottom plate 3, side baffle 4, bottom crossbeam 5, and strip support beam 6. DETAILED DESCRIPTION

[0019] The following is a further detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings, so as to provide a deeper understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solution, and the technical effects brought about. However, it should be noted that the description of these embodiments is illustrative only and does not constitute a specific limitation of the present invention.

[0020] like Figure 1As shown, the present invention includes a saccharification box consisting of a saccharification tank bottom plate 3 and four side baffles 4 fixed thereto. The saccharification box is a rectangular structure. The saccharification tank bottom plate 3 is provided with a plurality of ventilation holes arranged evenly at intervals. Each ventilation hole penetrates the upper and lower surfaces of the saccharification tank bottom plate 3. The outer surfaces of the four side baffles 4 are respectively provided with insulation grooves. A rubber-plastic insulation cotton structure layer is fixedly provided in the insulation grooves. A strip support beam 6 is fixedly provided on the lower surface of the saccharification tank bottom plate 3. The axis of the strip support beam 6 is arranged horizontally. Multiple strip support beams 6 are arranged at intervals along the length or width direction of the saccharification tank bottom plate 3. When the present invention is implemented, the wine saccharification fermentation tank can be stacked in multiple layers as a whole. Then, the temperature of the saccharified mash at the beginning and during the saccharification process is regulated by controlling the ambient temperature and humidity, which is conducive to large-scale batch production.

[0021] In order to facilitate the use of controlled ambient temperature and humidity to regulate the temperature of the saccharification mash at the beginning and during saccharification, the volume of the saccharification tank in the present invention is generally not designed to be too large, and two strip support beams 6 are generally arranged at intervals. The strip support beams 6 are generally preferably made of rectangular steel pipes. During use, the strip support beams 6 can ensure a certain vertical spacing between the bottom layer of saccharification tanks and the ground, and between the two adjacent layers of saccharification tanks, to ensure the ventilation effect of the saccharification tank bottom plate 3, so that there is good air flow between the mash and the environment, ensuring the supply of O2 during the growth of microorganisms, and also meeting the requirements of ensuring the initial temperature of the saccharification mash by raising the ambient temperature at the beginning of saccharification. At the same time, it can meet the requirements of promoting the temperature loss of the saccharification mash by lowering the ambient temperature when the saccharification temperature rises too fast during the saccharification process, thereby achieving the purpose of regulating the temperature of the saccharification mash during the saccharification process.

[0022] For ease of fabrication, a preferred embodiment comprises a top crossbeam 1 fixedly mounted on the top edges of each of the four side panels 4, which forms a top rectangular frame. A bottom crossbeam 5 fixedly mounted on the bottom edges of each of the four side panels 4 forms a bottom rectangular frame. The four corners of the top rectangular frame and the four corners of the bottom rectangular frame are fixedly connected by upright posts 2. The insulation groove corresponding to the outer surface of each side panel 4 is enclosed by the outer surface of the side panel 4, the top crossbeam 1, the bottom crossbeam 5, and the two upright posts 2. In certain alternative embodiments, the side panels 4 and the insulation groove may also be designed as a single piece. It is understood that to ensure overall insulation around the saccharification tank, the rubber-plastic insulation layer should cover as much of the side wall of the saccharification tank as possible. To further facilitate fabrication, the rubber-plastic insulation layer preferably comprises a molded rubber-plastic insulation board, which is secured within the insulation groove by adhesive bonding.

[0023] It can be understood that the material of the top cross beam 1, the column 2, the mashing tank bottom plate 3, the side baffle 4, the bottom cross beam 5 and the strip-shaped supporting beam 6 should meet certain strength requirements, and needs to meet the environmental health requirements of food processing, and the utility model is made of stainless steel material. The fixed connection between the top cross beam 1, the column 2, the mashing tank bottom plate 3, the side baffle 4, the bottom cross beam 5 and the strip-shaped supporting beam 6 can be realized by screw connection, welding and other conventional ways, and the utility model preferably adopts welding to fix as a whole.

[0024] In order to make the structure simple and practical, the ventilation hole on the mashing tank bottom plate 3 is preferably a strip-shaped hole. The size of the strip-shaped hole is preferably designed to be ≤3mm in width and ≥5mm in length, which not only ensures that the chaff and mashing dregs cannot leak out of the strip-shaped hole, but also ensures good air flow between the dregs and the environment, ensures the supply of O2 in the microbial growth process, and also meets the initial temperature of the mashing dregs by raising the environmental temperature in the initial stage of mashing, and at the same time, meets the temperature loss of the mashing dregs by reducing the environmental temperature when the mashing temperature rises too high in the mashing process, so as to achieve the purpose of temperature regulation of the mashing dregs in the mashing process.

[0025] In order to facilitate temperature regulation, the inner cavity depth of the mashing tank is preferably 400mm to 700mm. In specific implementation, the loading thickness of the mashing dregs is subject to the production process, and is generally controlled between 45cm and 60cm.

[0026] In order to facilitate cleaning, the mashing tank bottom plate 3 has a drain hole near the corner portion, and the drain hole penetrates the upper surface and the lower surface of the mashing tank bottom plate 3. The diameter of the drain hole is generally not less than 30mm, and in specific implementation, a conventional plug or drain valve can be used.

[0027] In order to facilitate transportation, the strip-shaped supporting beam 6 is provided with a forklift fork hole with an axis arranged in a horizontal direction, which is a positioning connection hole used in cooperation with the forklift fork.

[0028] In specific implementation, the utility model preferably proceeds according to the following process steps. First, the inner cavity of the mashing tank is cleaned, and the chaff with a thickness of 1cm to 2cm is spread on the bottom of the inner cavity of the mashing tank, and then the mashing dregs after cooking and cooling and adding koji are loaded into the mashing tank. During the loading process, the dregs should not be squeezed too hard, and the oxygen in the dregs should be ensured to meet the needs of microbial growth, and the dregs also have certain gaps for gas exchange with the environment.

[0029] The thickness of the mash depends on the production process, but is generally between 45cm and 60cm. After loading, spread a layer of rice husks evenly on the surface, with a thickness of 5cm ± 1cm. Use a forklift or AGV to transport the loaded mash bins to the saccharification area or fermentation room in the workshop and stack them in layers.

[0030] During the initial saccharification phase, the temperature in the fermentation room can be raised to the process requirements to ensure the initial saccharification temperature, which is conducive to the activation and growth of microorganisms in the mash. During saccharification process management, the temperature rise of the mash should be monitored appropriately. If the temperature rise is too slow, the ambient temperature can be appropriately increased to promote microbial growth. If the temperature rise is too rapid, the temperature can be controlled by lowering the ambient temperature and increasing ventilation.
