Description

Technical Field

[0001] The invention relates to the technical field of fermentation, in particular to an anti-floating deep fermentation tank for vegetables. Background Art

[0002] At present, ton jars and salting pools all use a relatively extensive processing method, with manual feeding and unloading, which is time-consuming and labor-intensive. In the fermentation industry, fermentation tanks are generally only suitable for liquid fermentation, and the inlet and outlet diameters are small, which cannot realize the automatic feeding and unloading of vegetables. In the fermentation process, in order not to affect the quality of vegetables, all vegetables need to be submerged in salt water. Among them, most salting pools are covered with plastic film, and salt, river sand, pebbles and even cement components are used for pressure. Ton jars use bamboo weaving and PE nets to prevent vegetables from floating. The above sealing methods often have problems such as incomplete oxygen isolation, film damage and leakage, and bamboo weaving mold, and may cause foreign matter such as mud and sand in the final product. In addition, during fermentation, when the fermentation tank is deep, due to the buoyancy of the fermentation water and vegetables, the vegetables are likely to float to the upper part of the fermentation tank, resulting in a decrease in the actual space utilization rate of the fermentation tank. As the fermentation proceeds, some substances in the fermentation water sink to the bottom of the fermentation tank, resulting in uneven composition of the fermentation water at different depths in the fermentation tank, and this unevenness will directly affect the fermentation results. From the above description, it can be seen that most vegetables will be located in the upper part of the fermentation tank during the fermentation process, but the concentration of effective ingredients in the fermentation water is low. The interaction between the two will directly affect the effect of vegetable fermentation. Summary of the invention

[0003] The present invention provides a vegetable anti-floating deep fermentation tank to solve the above-mentioned deficiencies in the prior art, solve the problem of being unable to protect the fermentation environment and adjust the concentration of fermentation water at different depths, and also solve the problem of low space utilization, and has strong practicality.

[0004] In order to achieve the purpose of the present invention, the following technologies are proposed: A vegetable anti-floating deep fermentation tank, comprising: a tank body, which serves as a container for vegetable fermentation. In order to facilitate real-time monitoring of the fermentation environment, corresponding monitors such as salinity, acidity, and oxygen content are arranged on it. In order to reduce manufacturing costs, the tank body itself is made of fiberglass, which has the advantages of high strength, low cost, corrosion resistance, aging resistance, and light weight. The lower part of the tank body can be optionally provided with a base, a bottom frame, etc. to ensure its stability after placement. A protective frame can also be provided on the outside of the tank body to support its exterior to further enhance its strength.

[0005] A sealing cover is provided at the upper end of the tank body, which can prevent the entry of bacteria and impurities, thereby creating a relatively closed and stable fermentation environment, and at the same time effectively improves the quality of the fermented vegetables.

[0006] The lower end of the tank body is connected with a connecting pipe, the other end of the connecting pipe is connected with a lower three-way valve, one of the ports of the lower three-way valve is connected with a drain pipe, the other port of the lower three-way valve is connected with a circulating water inlet pipe, the other end of the circulating connecting pipe is connected with a circulating pump, the circulating pump is connected with a circulating water outlet pipe, the other end of the circulating water outlet pipe is connected with an upper three-way valve, one of the ports of the upper three-way valve is connected with a water inlet pipe, the other port of the upper three-way valve is connected with a water inlet main pipe, the other end of the water inlet main pipe is connected to the upper end of the tank body. Through the arrangement of the above-mentioned components, the fermented water in the tank body can be circulated to make the fermented water uniform, so as to avoid the difference in the composition of the fermented water at different depths, which affects the fermentation of vegetables at different depths. The lower three-way valve is convenient for the discharge or circulation switching of the fermented water. The upper three-way valve is convenient for the injection of the fermented water and the injection switching of the circulating water.

[0007] A plurality of floating plates are arranged in the vertical direction in the tank body. When the vegetables at the bottom layer are placed, the floating plates can be used to apply pressure to the vegetables to prevent them from moving upward. By providing a plurality of floating plates, the fermented vegetables can be divided into a plurality of fermentation units to improve the utilization rate of the internal space of the tank body. When the vegetables are discharged, the vegetables can be floated by injecting salt water, and the vegetables on the lower floating plates can be taken out by taking out all the vegetables thereon, thereby facilitating the discharge operation of the vegetables.

[0008] Furthermore, the inner wall of the tank body is provided with a plurality of vertical bars. When the height of the tank body is high, the vertical bars can serve as internal reinforcement ribs to enhance the structural strength of the tank body. The outer periphery of the tank body is provided with a plurality of lifting ears, which facilitate the transfer of the tank body or the installation and fixation of its upper end.

[0009] Furthermore, the lower end of the tank body is formed with an arc-shaped tank bottom, and the connecting pipe is arranged on the arc-shaped tank bottom. The arc-shaped tank bottom facilitates the collection and discharge of fermented water. This arrangement is of great significance when the fermented water is discharged. A placement ring is provided at the lower end of the interior of the tank body. The placement ring is located above the arc-shaped tank bottom. A filter plate is placed on the placement ring. The filter plate is provided with a plurality of holes. The outer periphery of the filter plate is provided with a plurality of notches. Vertical bars are passed through the notches. When the fermented water is circulated, the filter plate can block and filter the vegetables above it to prevent the larger vegetables from being located at the entrance of the connecting pipe, which will cause the entrance of the connecting pipe to be blocked, thereby affecting the circulation or discharge of the fermented water. The placement ring plays a supporting role for the filter plate, and the filter plate is only placed on the placement ring to facilitate the thorough cleaning operation inside the tank body.

[0010] Furthermore, a plurality of slots are provided on the outer periphery of the float plate, and vertical bars are passed through the slots. When the float plate is put in or taken out, the vertical bars support the float plate to ensure its balance. When the float plate is placed, the posture of the float plate can be ensured not to change. When the float plate and the vegetables on it are taken out, the float plate is guided to prevent the float plate from tilting and causing the vegetables to fall.

[0011] Furthermore, a convex edge is formed on the outer periphery of the upper end of the tank body, and the setting of the convex edge can strengthen the structural strength of the upper end of the tank body to ensure the roundness of the upper end of the tank body. A sealing ring is formed on the outer periphery of the cover, and a ring groove is formed on the upper opening of the convex edge. The sealing ring is inserted into the ring groove, and when the sealing ring is inserted into the ring groove, there is a gap between the inner periphery, outer periphery and bottom end of the sealing ring and the inner wall and bottom of the ring groove, and the gap is filled with liquid, which is a solution that meets the food processing safety requirements and contains (or does not contain) antibacterial or sterilizing substances, such as salt solution. When the liquid is injected into the gap, the sealing ring and the convex edge can be sealed to prevent impurities, oxygen or miscellaneous bacteria from entering the interior of the tank body, thereby affecting the fermentation quality of the vegetables. Of course, in specific applications, the liquid can be regularly replenished or replaced to improve its sealing effect.

[0012] Furthermore, a plurality of through holes are provided on the floating plate, and during fermentation, the fermentation water can pass through the through holes, thereby facilitating the circulation operation of the fermentation water.

[0013] Furthermore, at least one handle is provided on the floating board. The provided handle is convenient for connecting to the handle through a hook on a crane when the vegetables are unloaded, so as to facilitate the removal of the vegetables. When the floating board is placed, it is also convenient for lifting and placing the floating board. The number of handles can be set to one. When there is one, the handle can be set at the geometric center of the floating board. It can also be a pair, and two handles need to be symmetrically arranged when setting. It can also be set to three or four. When three or more are set, the stability of the floating board when it is lifted or placed can be ensured.

[0014] Furthermore, the lower wall of the cover is formed with an inner concave cover, which is inserted into the upper end of the tank body, and there is an annular gap between the outer periphery of the inner concave cover and the inner periphery of the tank body. The cover is connected with a pair of vent pipes, and valves are provided on the vent pipes to control the passage and discharge of gas. The inner end of the vent pipe is connected with the annular gap, and one of the vent pipes is used to pass gas into the interior of the tank body, and the other vent pipe is used to discharge the gas inside the tank body. When fermenting, in order to control the atmosphere inside the tank body to ensure the fermentation quality. Therefore, a vent pipe is provided on the cover, and after adding salt water to the dishes, nitrogen, carbon dioxide, etc. can be filled into the space above the liquid level inside the tank body through the vent pipe, and during injection, oxygen, etc. inside the tank body are discharged through another vent pipe to ensure the fermentation environment.

[0015] Furthermore, a cover plate is provided at the upper end of the sealing cover, which is covered on the open end of the inner concave cover, and the cover plate is connected with an inlet pipe and a discharge pipe, and the lower end of the discharge pipe extends to the bottom of the inner concave cover. The cover plate is fixed on the sealing cover by pasting or the like. Firstly, it is convenient to form the sealing structure. Secondly, during the fermentation process, a large amount of gas will be generated due to the reproduction of microorganisms and the like, and the generation of these gases will inevitably lift up the sealing cover, thereby affecting the sealing effect of the sealing cover. In addition, during the fermentation process, vegetables will also float up, so it is also easy for the sealing cover to move upward. Therefore, the inner concave cover is provided and liquids such as water are injected into it to improve the safety and stability of the sealing cover after it is installed.

[0016] Furthermore, a plurality of lifting ears are provided on the cover to facilitate the covering and uncovering operations of the cover.

[0017] The advantages of the above technical solution are: The present invention improves the fermentation environment of large-scale vegetable fermentation, and can avoid adverse effects of external impurities, bacteria, oxygen, etc. on fermentation during fermentation. Second, it can improve the space utilization rate of the fermentation environment. Third, it is convenient for the operation of feeding and discharging vegetables during fermentation. Third, it can ensure that the fermentation water at different depths can be uniform, thereby ensuring the fermentation quality of vegetables. BRIEF DESCRIPTION OF THE DRAWINGS
