Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation container technology, and in particular to a one-way exhaust fermenter. Background Technology
[0002] When making fermented foods, clean fermentation containers must be used to hold the ingredients to prevent them from molding or spoiling during fermentation. A large amount of gas will be produced inside the container during the fermentation process. Therefore, it is necessary to release the gas from the fermentation container regularly to prevent it from bursting or rupturing.
[0003] Most of the sealed fermentation containers widely used in the market have solid-liquid separation and venting structures; however, these products often have the following problems:
[0004] 1) Solid-liquid separation uses a separate, separable food-grade silicone mesh. The mesh needs to be frequently disassembled and cleaned, and the silicone mesh has cleaning dead corners. It is difficult to keep it completely clean after long-term use. The dirt left on the mesh can easily cause the food to mold and spoil during fermentation.
[0005] 2) Most venting structures employ spring-loaded vent valves, perforated caps, or water-sealed structures. The first two types of venting require manual periodic pressing of the vent valve or opening of the cap to release gas, which can prevent the timely expulsion of gas generated inside the container, posing a safety hazard of container explosion. Manual venting can also lead to excessive pressure inside the container due to the inability to release gas promptly, potentially causing liquid splashing and contaminating the food inside. While the latter type of venting, thanks to the water barrier, can release gas promptly while preventing contamination of the food inside the container, it requires periodic manual water replenishment to prevent the sealing effect from decreasing due to evaporation. Furthermore, water-sealed structures are inconvenient for transportation. Utility Model Content

[0032] Example
[0033] like Figure 1 and Figure 8 As shown, according to an embodiment of the present invention, a one-way exhaust fermentation tank is provided, which includes a tank body 1, a filter structure 103, a first cover 2, a vent plug 202, a second cover 203, a knob 207, and a third cover 3.
[0034] Preferably, the filter structure 103 and the tank body 1 are made of glass, and the filter structure 103 is welded to the inner wall of the tank body 1 to form an integrated structure. The vent plug 202 is made of ePTFE (expanded polytetrafluoroethylene membrane) material with hydrophobic and breathable structural characteristics.
[0035] Specifically, the can body 1 has a first opening 101 and a second opening 102. After the filter structure 103 is welded to the inside of the can body 1, it divides the inside of the can body 1 into a first accommodating space 101a and a second accommodating space 102a. The first accommodating space 101a and the second accommodating space 102a are respectively connected to the outside of the can body 1 through the first opening 101 and the second opening 102. The filter structure 103 has multiple first through holes 103a to allow the first accommodating space 101a and the second accommodating space 102a to communicate with each other. The first cover 2 and the third cover 3 are respectively detachably assembled to the first opening 101 and the second opening 102 through threaded structures. The first accommodating space 101a, the second accommodating space 102a, the filter structure 103, and the multiple first through holes 103a on the filter structure 103 can realize solid-liquid separation inside the can body 1, thereby facilitating users to put or take food or liquid into the can body 1 through the first opening 101 and / or the second opening 102.
[0036] Specifically, the inner side of the first cover 2 has a first groove 201, the bottom of the first groove 201 has a second through hole 201a, the inside of the first groove 201 is filled with a vent plug 202, and a detachable second cover 203 is provided at the first groove 201. The second cover 203 has multiple third through holes 203a. Due to the hydrophobic and breathable structural characteristics of ePTFE material, the gas generated during fermentation of the food inside the can can be discharged to the outside of the can 1 sequentially through the third through holes 203a, the vent plug 202, and the second through holes 201a under the action of the internal air pressure. At the same time, the liquid or droplets outside and inside the can 1 are blocked by the vent plug 202, preventing mutual flow and thus avoiding mold and spoilage of the food inside the can during fermentation. The second cover 203 can also block the floating foreign matter generated during the gas exhaust process of food fermentation, preventing the accumulation of foreign matter on the vent plug 202 and causing blockage of the second through holes 201a, thus affecting the exhaust effect.
[0037] Specifically, the inner side of the first cover 2 has a first isolation wall 204 that matches the first opening 101. A first sealing groove 204a is formed between the first isolation wall 204 and the inner peripheral wall of the first cover 2, and a first sealing ring 205 is filled in the first sealing groove 204a. The inner side of the third cover 3 has a second isolation wall 301 that matches the second opening 102. A second sealing groove 301a is formed between the second isolation wall 301 and the inner peripheral wall of the third cover 3, and a second sealing ring 302 is filled in the second sealing groove 301a. The first sealing ring 205 and the second sealing ring 302 can further seal the tank 1, preventing liquid leakage at the connection between the first cover 2 and the third cover 3 and the two openings of the tank 1.
[0038] Specifically, a second groove 206 is provided on the top side of the first cover 2, and a first engaging portion 206a is provided at the bottom of the second groove 206. The knob 207 is rotatably engaged with the first engaging portion 206a of the second groove 206 through the second engaging portion 207a at its bottom, so that the knob 207 can rotate freely relative to the first cover 2 within the second groove 206. Multiple scale textures 208 are provided on the top side of the first cover 2 corresponding to the knob 207. The multiple scale textures 208 can be date numbers and are evenly distributed around the knob 207. A pointer texture 207b pointing in a preset direction is provided on the knob 207. The user can rotate the knob 207 to make the pointer texture 207b point to the corresponding scale texture 208, thereby recording the fermentation date of the food in the jar.
[0039] Optionally, the welded joint between the filter structure 103 and the inner wall of the first accommodating space 101a is formed into a first rounded corner structure 101b through a welding process; the welded joint between the filter structure 103 and the inner wall of the second accommodating space 102a is formed into a second rounded corner structure 102b through a welding process. The first rounded corner structure 101b and the second rounded corner structure 102b can further reduce the cleaning dead corners inside the tank and the filter structure 103, so that the user can thoroughly clean the filter structure 103.
[0040] Optionally, the embodiment of this utility model provides a one-way exhaust fermentation tank that does not limit the type and number of the first through holes 103a opened on the filter structure 103. Users can choose the tank body 1 with a filter structure 103 having a suitable type and number of first through holes 103a according to the type and size of the food being fermented in the tank.
[0041] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0042] Compared with the prior art, the unidirectional venting fermentation tank provided in the above embodiments of this utility model has a glass filter structure 103 integrated with the tank body. This filter structure 103 does not require frequent disassembly and cleaning, and the glass material is easier to clean than the traditional silicone material, thus ensuring that the food does not mold or spoil during the fermentation process. The unidirectional venting fermentation tank has a first cover 2 and a third cover 3 at both ends, respectively. Both the first cover 2 and the third cover 3 can be opened to put in or take out food, and the filter structure 103 can realize a solid-liquid separation scheme by taking out solid food from one side and pouring out liquid from the other side. The first lid 2 has a second through hole 201a for venting. A breathable plug 202 made of ePTFE material is installed on the inner side of the first lid 2 corresponding to the second through hole 201a. This breathable plug 202 has hydrophobic and breathable properties, ensuring that when the gas generated during fermentation is released through the breathable plug 202 and the second through hole 201a, no liquid leaks from the inside of the container, and no dirt flows in from the outside. This achieves timely venting while preventing the food inside from molding or spoiling, and also facilitates transportation. Furthermore, the knob 207 and graduated markings 208 on the first lid 2 allow users to easily record the fermentation date of the food inside the container.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
