Description

Technical Field

[0001] The present application relates to a fermentation tank, and in particular to a fermentation tank capable of effectively sealing an internal space to isolate the internal space from the outside air. Background Art

[0002] Solid-state fermentation of pure grains is a common traditional winemaking process. For example, the brewing process of sorghum wine is roughly divided into three parts: koji making, wine making and packaging. The wine making process includes soaking, steaming, cooling, mixing koji, fermentation, distillation, cooling, re-mixing koji, re-fermentation and re-distillation.

[0003] Whether brewing or distilling liquor, mash fermentation is an important step. It mainly involves putting appropriate proportions of koji, raw materials and water into a fermentation tank and mixing them into mash. After mashing, the koji enzyme hydrolyzes starch into sugar, and the yeast converts the sugar into alcohol. The mash ferments in a low temperature environment for about several days to dozens of days.

[0004] Traditional fermentation is carried out in mud, cement, and red brick troughs. Cement cellars are commonly used in Taiwan, China, and the bacteria can attach to the inner wall, causing different fermentation tanks to have different flavors of wine due to the different attached bacteria species or different amounts of attachment. At the same time, after long-term use of these fermentation containers, the various bacteria species multiply, giving the wine the flavor of an old cellar.

[0005] In the prior art, during the fermentation process, the fermentation tank (or fermentation cylinder / fermentation tank / fermentation tank car, etc.) needs to be covered with plastic sheeting to block the outside air, so as to prevent oxygen from entering and destroying the anaerobic fermentation environment, causing production failure. Utility Model Content

[0006] However, solid-state fermentation will gradually reduce the total solid volume of the raw materials over time, resulting in a gradual increase in the gas space and gas content in the fermentation tank. However, in the aforementioned method of covering with plastic sheeting, the plastic sheeting will sink as the volume of the raw materials decreases. However, there are a large number of fermentation tanks, which may be dozens, hundreds or even more. The operation of manually covering the fermentation tanks with plastic sheeting is obviously labor-intensive, time-consuming and increases labor costs, and does not meet the needs of today's industrialized society for speed and efficiency.

[0007] In view of the above-mentioned shortcomings that still need to be improved, the applicant in this case believes that it is necessary to conceive a fermentation tank that can effectively seal the internal space to isolate it from the outside air, so as to solve the problem of labor-intensive and inefficient operations in the past.

[0008] In order to achieve the above-mentioned purpose, the present application provides a fermentation tank, comprising a containing tank and a tank cover. The containing tank comprises a tank body having a notch on the top side for placing objects. The tank cover is arranged on the notch of the tank body, and comprises a cover body covering the notch, and a clamping part arranged around the edge of the cover body, the cover body closes the notch in the vertical direction, and the clamping part closes the inner and outer sides of the notch in the horizontal direction.

[0009] Furthermore, the locking portion includes an inner clamping piece erected on the edge of the cover body, a connecting piece erected on the top of the inner clamping piece and extending outward, and an outer clamping piece erected on the edge of the connecting piece relative to the inner clamping piece. The inner clamping piece, the connecting piece and the outer clamping piece together form a groove for the notch on the top side of the slot body to be inserted into.

[0010] Furthermore, the cross-section direction of the engaging portion is U-shaped.

[0011] Furthermore, the engaging portion is combined with the cover body through an integral molding method or a welding method.

[0012] Furthermore, the tank cover is made of stainless steel.

[0013] Furthermore, a handle is provided on the top side of the cover body.

[0014] Furthermore, the tank body and / or the cover body is provided with a gas check valve for unidirectionally discharging gas outward.

[0015] Furthermore, the tank body is provided with a liquid check valve for discharging liquid outward in a one-way manner.

[0016] Furthermore, the cross-section of one side of the slot body is U-shaped.

[0017] Furthermore, the tank body is made of stainless steel.

[0018] The tank cover of the present application seals the fermentation tank, effectively controls the amount of oxygen in the tank, provides an ideal fermentation environment and isolates external pollution. It not only solves the problem of low efficiency of using plastic cloth for covering in the past, but also does not require the addition of rice or the turning of the mash during the fermentation process. While improving efficiency, it can also ensure and enhance the flavor and quality of the final fermentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The tank body 11 is provided with a liquid check valve Q for one-way discharge of liquid outward. The liquid check valve Q is, for example but not limited to, provided near the bottom side of the tank body 11 (such as " Figure 1 In actual application, the liquid check valve Q has the function of one-way liquid discharge, and the liquid product produced during the fermentation process is discharged from the tank body 11 without opening the tank cover 20, ensuring and maintaining the smooth production of fermented mash under pure solid conditions.

[0041] Please also refer to " Figure 2 "to" Figure 3 ", is a schematic cross-sectional view of the fermentation tank of the present application from different viewing angles, as shown in the figure.

[0042] The slot cover 20 is disposed on the slot opening O of the slot body 11. The slot cover 20 includes a cover body 21 covering the slot opening O, and a snap-fitting portion 22 disposed around the edge of the cover body 21. The cover body 21 closes the slot opening O in the vertical direction, and the snap-fitting portion 22 closes the inner and outer sides of the slot opening O in the horizontal direction. The "vertical direction" here refers to the direction of the cover body 21 toward the slot opening O, and the "horizontal direction" refers to the direction of the snap-fitting portion 22 toward the inner and outer sides of the slot opening O. The slot cover 20 is made of stainless steel, which has the advantages of preventing bacteria, being easy to clean, and not requiring the use of detergents.

[0043] The engaging portion 22 is combined with the cover body 21 by, for example but not limited to, integral forming, welding or other methods and structures. The aforementioned integral forming method is, for example but not limited to, cold forging, hot forging, pressing, cutting or other processing methods.

[0044] A handle is provided on the top side of the cover body 21, or a handle is provided on any outward side of the slot cover 20 (not shown), for example but not limited to being provided on any outward side of the locking portion 22 (such as the top side, side, or bottom side, etc.), to facilitate taking the slot cover 20.

[0045] A thermometer (not shown) inserted into the interior of the trough body 11 is provided on the top side of the cover body 21 or any side of the trough body 11 to measure the internal temperature of the trough body 11; on the other hand, a sealing gasket (not shown) is provided between the aforementioned thermometer and the structure (the cover body 21 or the trough body 11) to ensure that the interior of the trough body 11 is closed.

[0046] The locking portion 22 includes an inner clamping piece 221 erected on the edge of the cover body 21, a connecting piece 222 erected on the top end of the inner clamping piece 221 and extending outward, and an outer clamping piece 223 erected on the edge of the connecting piece 222 relative to the inner clamping piece 221. The inner clamping piece 221, the connecting piece 222 and the outer clamping piece 223 together form a groove for the notch on the top side of the slot body 11 to be inserted. The shape and size of the inner side of the groove are roughly equal to, or slightly larger than the shape and size of the inner and outer sides of the notch O on the top side of the slot body 11 based on the tolerance reserved for assembly, so that the slot cover 20 can actually cover the notch O of the slot body.

[0047] In one embodiment, if Figure 2 " As shown in the figure, the cross-sectional direction of the engaging portion 22 is in the shape of a U, that is, the inner clamping piece 221, the connecting piece 222 and the outer clamping piece 223 are all planar plates to form a U-shaped cross-sectional surface together. In another embodiment, the cross-sectional direction of the engaging portion 22 is in the shape of an inverted U (not shown), that is, the inner clamping piece 221 and the outer clamping piece 223 are all planar plates, and the connecting piece 222 is a plate bent into a C-shape or a U-shape, so that the above three together form an inverted U-shaped cross-sectional surface. In yet another embodiment, the difference from the previous two embodiments is that an acute angle is sandwiched between the inner clamping piece 221 and / or the outer clamping piece 223 and the connecting piece 222, so that the inner clamping piece 221 and / or the outer clamping piece 223 can provide pressure to the inner and / or outer sides of the slot opening O of the slot body 11 for clamping. The present application does not intend to limit the cross-sectional shape of the engaging portion 22 , which is explained here first.

[0048] In order to prevent the accumulation of air generated during the fermentation process from causing the barrel to explode, the tank body 11 (such as " Figure 1 " as shown) and / or the cover body 21 (not shown) is provided with a gas check valve A for unidirectionally discharging gas outward, that is, at least one of the tank body 11 and the cover body 21 is provided with the gas check valve A to release the pressure generated by the internal gas, wherein the gas check valve A is preferably arranged at a position of the tank body 11 close to the notch O to avoid the internal liquid from flowing out. In actual application, the gas check valve A has the function of unidirectional air release, and the gas generated during the fermentation process is discharged without opening the tank cover 20, thereby preventing the internal pressure of the tank body 11 from being too high, and at the same time avoiding the fermentation failure caused by the outside air entering the tank body 11.

[0049] In summary, the tank cover of the present application seals the fermentation tank, effectively controls the amount of oxygen in the tank, provides an ideal fermentation environment and isolates external pollution. It not only solves the problem of low efficiency of using plastic cloth for covering in the past, but also does not require the addition of rice or the turning of the mash during the fermentation process. While improving efficiency, it can also ensure and enhance the flavor and quality of the final fermentation.
