Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a vegetable fermentation tank. Background Art
[0002] Vegetable fermentation is a traditional food preservation method that transforms vegetables into foods rich in probiotics and other nutrients through the action of beneficial microorganisms. During the fermentation process, lactic acid bacteria convert the sugars in the vegetables into lactic acid in an oxygen-free environment. This process not only increases the shelf life of the food, but also improves its flavor and nutritional value.
[0003] Commonly used vegetable fermentation facilities are pottery jars or cellars. Pottery jar fermentation offers the following advantages: First, small-batch fermentation: Pottery jars typically have a smaller capacity, making them suitable for small-scale fermentation and easier to manage. Second, breathability: The material of pottery jars is relatively breathable, allowing trace amounts of oxygen to permeate. This helps create a specific microbial environment, favoring the flavor development of certain types of wine. Third, temperature control: Pottery jars offer excellent thermal insulation, maintaining a relatively stable temperature environment, an advantage for wines that require constant temperature fermentation. Fourth, flavor contribution: Trace minerals in pottery jars may leach into the wine, providing additional flavor. Cellar fermentation offers the following advantages: First, large-batch fermentation: Cellars have a larger capacity, making them suitable for large-scale fermentation production. Second, controlled environment: Cellars offer a more enclosed environment, allowing for better control of temperature and humidity, which is crucial for certain wines that require strictly controlled fermentation conditions. Third, deep fermentation: The depth of the cellars helps create a stratified fermentation environment, allowing materials at different depths to experience different fermentation rates and conditions. Fourth, long fermentation times: The fermentation cycle in the cellar is long, sometimes lasting months to years, such as in the production of certain liquors. The above two characteristics show that while ceramic jars offer significant advantages during fermentation, their limited use in industrial production is limited by their limited use for small-batch fermentation operations. While underground cellars can achieve large-scale fermentation, they are difficult to control during the fermentation process, often allowing bacteria to enter and affect the fermentation results. Furthermore, they are inconvenient for controlling the fermentation process of vegetables and require a large floor space. Stainless steel fermentation tanks are also currently available, but their high cost leads to limited actual use. Furthermore, the temperature control system used to control the fermentation process further increases the cost of these fermentation tanks. Utility Model Content
[0004] The utility model provides a vegetable fermentation tank to solve the deficiencies of the prior art, reduce the manufacturing cost, and effectively control the fermentation process, thereby having strong practicality.
[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0006] A vegetable fermentation tank comprises a tank body and a tank lid. A first tube is provided at the lower end of the tank body, and a first valve is provided on the first tube. The first tube facilitates the discharge of fermentation water or cleaning water from the tank body. A ridge is provided at the upper end of the tank body. The longitudinal section of the ridge is L-shaped, and an annular cavity is formed between the ridge and the outer wall of the tank body. During the fermentation process, the annular cavity is filled with water. By injecting water, the gap between the tank body and the tank lid is sealed to prevent the entry of bacteria, thereby facilitating quality control of the fermentation process. The tank lid is buckled onto the upper end of the tank body. A ring plate is provided on the outer periphery of the tank lid, and the ring plate is inserted into the annular cavity. The tank lid is provided with multiple air holes. Gas generated during the fermentation process can be discharged through the air holes to prevent the gas generated during the fermentation process from lifting the tank lid and affecting the sealing effect. Of course, in order to prevent the entry of bacteria, an activated carbon canister can be placed on it to adsorb impurities.
[0007] Furthermore, the lower end of the tank body is connected to a second pipe, and a second valve is provided on the second pipe. During the fermentation process, in order to circulate the fermentation water or control the water temperature of the fermentation water, the second pipe is provided to facilitate the circulation of the fermentation water.
[0008] Furthermore, a third tube and a fourth tube are provided on the convex edge, and the third tube and the fourth tube are connected to the annular cavity. The third tube extends downward, and the fourth tube extends laterally outward. The third tube and the fourth tube are respectively provided with a one-way valve. During the fermentation process, when a large amount of gas is generated, in order to prevent the sealing water in the annular cavity from overflowing from the convex edge, the fourth tube is provided for water level control of the sealing water, and the third tube can supplement the sealing water according to the water level of the sealing water, thereby ensuring the sealing effect, and the water replenishment operation of the third tube is performed automatically.
[0009] Furthermore, the tank cover is made of polyvinyl chloride, which is lightweight and has a low manufacturing cost, thereby increasing the possibility of promoting and applying the fermentation tank in the market.
[0010] Furthermore, a pair of handles are provided on the can lid to facilitate the closing and opening operations of the can lid.
[0011] Furthermore, the tank body is made of glass fiber reinforced plastic, which not only ensures the overall strength of the tank body but also reduces the manufacturing cost of the tank body.
[0012] Furthermore, there is a gap between the lower end of the ring plate and the lower end of the annular cavity, a gap between the inner peripheral wall of the ring plate and the outer peripheral wall of the tank body, and a gap between the outer peripheral wall of the ring plate and the inner peripheral wall of the flange. The presence of these gaps allows the sealing water to be evenly filled inside and outside the annular cavity, thereby improving its sealing effect.
[0013] Furthermore, a concave shell is formed on the can cover which is concave downwards.
[0014] Furthermore, the upper end of the tank is equipped with multiple baffles, with gaps between them. During the fermentation process, a large amount of gas is generated, and as the gas increases, the vegetables will move upward. As the vegetables move upward, the gas will act on the lid, pushing up the lid, thus affecting the sealing effect. To solve this problem, baffles are installed inside the tank. During fermentation, multiple horizontal wooden, bamboo, and steel bars are placed under the baffles to prevent the vegetables from moving upward. The multi-section structure is processed to facilitate the placement and removal of the horizontal wooden, bamboo, and steel bars.
[0015] Furthermore, a support is welded to the lower end of the tank body, and the support includes three support rods welded to the lower end of the tank body. The lower end of the support rod is provided with a mounting plate. The adjacent two support rods are connected together by a connecting plate, and the mounting plate is fixed to the ground by bolts.
[0016] The advantages of the above technical solution are:
[0017] The utility model reduces the cost of the fermentation tank and facilitates the control of the fermentation process, thereby improving the quality of vegetable fermentation. BRIEF DESCRIPTION OF THE DRAWINGS
