Description

Technical Field

[0001] This utility model relates to the field of fermentation agent production and processing technology, and in particular to an indoor fermentation rack for fermented glutinous rice. Background Technology

[0002] In the indoor production process of fermented glutinous rice (laozao) starter culture, the fermentation rack is one of the key pieces of equipment. Traditional indoor fermentation racks for laozao starter culture have a relatively simple structure, typically consisting of only a frame and a placement surface. The storage units are mostly fixed, making flexible disassembly and assembly difficult. This structure has several drawbacks. On the one hand, it is inconvenient and inefficient to place and retrieve the starter culture. On the other hand, due to the lack of a reasonable positioning and fixing structure, the storage units are prone to shaking and shifting on the fermentation rack, affecting the stability and safety of the fermentation process. Furthermore, the storage units of traditional fermentation racks have poor air permeability, which is detrimental to gas exchange and heat dissipation during fermentation, making it difficult to guarantee the fermentation quality and effect. Additionally, the storage units often use ordinary snap-fit ​​or locking structures for closure, resulting in poor sealing and cumbersome operation, which is not conducive to improving production efficiency. Therefore, there is an urgent need to design a new type of indoor fermentation rack for laozao starter culture to solve the problems existing in traditional fermentation racks. Summary of the Invention

[0003] The technical problem this utility model aims to solve is to provide an indoor fermentation rack for fermented rice wine starter, which is modularly stored, facilitating overall loading and unloading, and allowing for flexible adjustment of storage space according to actual production needs, greatly improving operational convenience and efficiency. The removable ventilated grid plate in the mounting groove at the bottom of the frame ensures good air permeability while preventing fragments from falling onto the fermentation unit below during fermentation, providing a more suitable fermentation environment and helping to improve fermentation quality and effect. The removable nature of the ventilated grid plate maintains good air permeability while allowing larger particles of impurities to pass through and preventing fragments from falling off the starter during fermentation from the upper part of the rack into the storage unit below.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an indoor fermentation rack for fermented rice wine, including a rack structure and multiple storage units that cooperate with it. The rack structure includes symmetrically arranged support frames, and multiple layers of mutually cooperating placement racks are provided between the symmetrically arranged support frames. Each layer of placement rack is equipped with a storage unit.

[0005] The storage unit includes a bottom frame, one side of which is connected to a top frame via a hinge structure. The bottom frame has a bottom mesh, and the top frame has a top mesh.

[0011] In a preferred embodiment, the gap between the breathable grilles does not exceed five millimeters.

[0012] The indoor fermentation rack for fermented glutinous rice provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0013] (1) Unitized storage not only facilitates overall loading and unloading, but also allows for flexible adjustment of storage space according to actual production needs, greatly improving the convenience and efficiency of operation.

[0014] (2) The removable air-permeable grid plate in the mounting groove at the bottom of the bottom frame can ensure good air permeability while preventing the broken material from falling onto the fermentation unit below during fermentation, thus providing a more suitable fermentation environment and helping to improve the fermentation quality and effect.

[0015] (3) The detachable nature of the air-permeable grid plate can maintain good air permeability while allowing larger particles of impurities to pass through and preventing the debris that falls off during the fermentation of the above-ground fermenting agent from falling into the storage unit below.

[0023] like Figure 1-4 In the middle, the fermentation rack for fermented rice wine includes a frame structure 1 and multiple storage units 2 that cooperate with it. The frame structure 1 includes symmetrically arranged support frames 3, and multiple layers of mutually cooperating placement racks 4 are provided between the symmetrically arranged support frames 3. Each layer of placement rack 4 is equipped with a storage unit 2.

[0024] The storage unit 2 includes a bottom frame 6, one side of which is connected to a top frame 8 via a hinge structure 7. A bottom mesh 10 is provided on the bottom frame 6, and a top mesh 11 is provided on the top frame 8.

[0025] In a preferred embodiment, the bottom frame 6 is provided with symmetrical positioning grooves 9, which cooperate with the positioning strips 5 provided on the placement rack 4.

[0026] In a preferred embodiment, the bottom of the base frame 6 is provided with a mounting groove 14, and a ventilation grille 15 is provided in the mounting groove 14 for disassembly and assembly. The ventilation grille 15 is provided with a pull buckle 16.

[0027] In a preferred embodiment, the bottom frame 6 is provided with a magnetic strip 12, and the top frame 8 is provided with a mating strip 13 that magnetically engages with the magnetic strip 12.

[0028] In a preferred embodiment, the top frame 8 is provided with a handle 17.

[0029] In a preferred embodiment, the diameter of the top net 11 is smaller than the diameter of the bottom net 10.

[0030] In a preferred embodiment, the gap between the breathable grilles 15 does not exceed five millimeters.

[0031] Example 2:

[0032] like Figure 1-2 In the middle, the support frame 3 is made of high-strength metal material and is fixed to the ground or wall through welding process to ensure its stability;

[0033] Between the symmetrically arranged support frames 3, multiple layers of mutually cooperating placement racks 4 are installed according to design requirements by means of bolt connection, etc. The spacing between the layers of the placement racks 4 is adjusted according to actual usage needs to accommodate the placement of storage units 2 of different numbers and sizes.

[0034] On each shelf 4, positioning strips 5 are set at certain intervals and positions. The positioning strips 5 are made of the same material as the shelf and are fixed to the shelf 4 by welding or bolts.

[0035] Example 3:

[0036] like Figure 3-4 In the middle, both the bottom frame 6 and the top frame 8 are made of lightweight, corrosion-resistant plastic material and are formed by injection molding.

[0037] A hinge structure 7 is installed on one side of the bottom frame 6, connecting the bottom frame 6 and the top frame 8 through the hinge structure 7, so that the top frame 8 can rotate around the hinge structure 7, thereby opening and closing the storage unit 2.

[0038] Install the bottom mesh 10 on the bottom frame 6. The bottom mesh 10 is fixed to the bottom frame 6 with screws to ensure a firm installation.

[0039] Install the top mesh 11 on the top frame 8, also using screws for fixing;

[0040] Symmetrical positioning grooves 9 are machined on the bottom frame 6, and the size and shape of the positioning grooves 9 match the positioning strips 5 on the placement frame 4.

[0041] A mounting groove 14 is provided at the bottom of the bottom frame 6. The size of the mounting groove 14 is designed according to the size of the ventilation grille 15 to ensure that the ventilation grille 15 can be smoothly installed in the mounting groove 14.

[0042] A magnetic strip 12 is installed on the bottom frame 6. The magnetic strip 12 is installed on the bottom frame 6 by means of glue or slot fixation.

[0043] Install a mating strip 13 on the top frame 8 that magnetically engages with the magnetic strip 12, using the same installation method as the magnetic strip 12.

[0044] The working principle of this utility model is as follows: the positioning groove 9 on the bottom frame 6 of the storage unit 2 cooperates with the positioning strip 5 on the placement rack 4. When the storage unit 2 is placed on the placement rack 4, the positioning groove 9 slides down along the positioning strip 5 until the storage unit 2 is completely seated on the placement rack 4, thereby achieving accurate positioning and stable fixation of the storage unit 2 on the placement rack 4 and preventing the storage unit 2 from shaking and shifting during use.

[0045] The bottom frame 6 and the top frame 8 are connected by a hinge structure 7. The operator can easily open or close the storage unit 2 through the handle 47 on the top frame 8. When the storage unit 2 is closed, the magnetic strip 12 on the bottom frame 6 and the mating strip 13 on the top frame 8 attract each other and connect tightly to form a good sealing effect, preventing external impurities from entering the storage unit 5. At the same time, it also helps to maintain the stability of the fermentation environment inside the storage unit 5.

[0046] The ventilation grid 15 installed in the bottom mounting groove 14 of the bottom frame 6 has a gap of no more than five millimeters. While ensuring that the gas can be exchanged smoothly and the heat can be effectively dissipated during the fermentation of the fermented gluten, it can also prevent large particles of impurities from entering the storage unit 2. It can also prevent the residue of the fermented gluten from falling into the storage unit 2 below, thus avoiding contamination of the fermented gluten. Operators can easily remove the ventilation grid 15 by pulling the buckle 16 according to the actual fermentation needs to adjust the ventilation or clean the inside of the storage unit 2.

[0047] The beneficial effects of this utility model are as follows: Unitized storage facilitates overall loading and unloading, and allows for flexible adjustment of storage space according to actual production needs, greatly improving the convenience and efficiency of operation; the removable ventilated grid plate in the mounting groove at the bottom of the frame ensures good air permeability while preventing fragments from falling onto the fermentation unit below during fermentation, providing a more suitable fermentation environment and helping to improve fermentation quality and effect; the removable nature of the ventilated grid plate maintains good air permeability while allowing larger particles of impurities to pass through and preventing fragments from falling off the fermenting agent above into the storage unit below.
