Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tank covers, in particular to an auxiliary pressure cover for yogurt fermentation. Background Art

[0002] Yogurt fermentation auxiliary capping may refer to an auxiliary tool or equipment used in the yogurt fermentation process to seal or cap the yogurt container. This capping can ensure that the yogurt is in a relatively closed environment during the fermentation process, which is conducive to the reproduction of probiotics and the production of lactic acid, thereby promoting the fermentation process of yogurt. The capping can seal the yogurt container manually or automatically. During the sealing process, the capping will apply a certain amount of pressure to ensure that the seal is tight and leak-free. At the same time, the capping can also protect the yogurt and prevent contamination by external microorganisms.

[0003] The Chinese patent publication number is CN211367529U, which discloses a feeding cover for a yeast fermentation tank with strong sealing performance, including a yeast fermentation tank body, the upper end of the yeast fermentation tank body is integrally provided with a yeast fermentation tank mouth, the outer cover of the yeast fermentation tank mouth is covered with a yeast fermentation tank cover, and a circle of clamping ring is fixedly welded at the outer circle of the yeast fermentation tank cover, and the clamping ring is sleeved on the outer circle of the yeast fermentation tank mouth. In the utility model, the yeast fermentation tank cover is triple-sealed, has good sealing, and improves the efficiency of fermentation; the yeast fermentation tank cover in the utility model can be quickly fixed, ensuring strong connection strength and convenient opening and use; the sealing ring in the utility model is fixed to the joint between the yeast fermentation tank mouth and the yeast fermentation tank cover by a magnetic suction ring or a spring, which can be compressed and sealed in real time, has a long service life, and replaces the method of directly compressing and sealing the sealing ring by squeezing the sealing cover in the prior art.

[0004] The above-mentioned prior art solution has the following defects: it uses the setting of a spring to push the inner rubber sealing ring toward the mouth of the yeast fermentation tank, but the rubber sealing ring is a flexible structure. When pressure is applied to a part of the rubber sealing ring, the pressed area is stretched, which will cause the unpressed area of ​​the rubber ring to be redundant. When the rubber ring ages after long-term use, the redundant area will leak, allowing outside air to enter the tank, which may bring in harmful microorganisms and also affect the stability of the temperature in the tank. Therefore, we propose a yogurt fermentation auxiliary pressure cap to solve the above-mentioned problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the utility model is connected, the gland body is placed above the fermentation tank. Due to the inclined setting above the positioning protrusion, when the lower positioning edge of the gland body and the positioning protrusion are slightly misaligned with each other, the gland body can be guided to rotate when moving downward, so that the lower positioning edge and the positioning protrusion are meshed, and the gap between the lower positioning edge and the positioning protrusion is sealed by the setting of the first sealing strip. At this time, the locking electric telescopic cylinder is extended, and the locking electric telescopic cylinder pushes the push plate, and the push plate slides along the locking electric telescopic cylinder groove. The push plate pushes the locking block through the connecting rod. When the locking block contacts the positioning block, due to the setting of the inclined edge between the two, the locking block moves toward the fermentation tank. When the fermentation tank approaches, the horizontal movement will be converted into the vertical movement of the pressure cover body, and the pressure cover body and the fermentation tank will be clamped, so as to improve the sealing effect during the connection, and solve the problem that the existing fermentation tank cover uses the spring to push the inner rubber sealing ring toward the mouth of the yeast fermentation tank, but the rubber sealing ring is a flexible structure. When pressure is applied to a part of the rubber sealing ring, the pressed area is stretched, which will cause the unpressed area of ​​the rubber ring to be redundant. When the rubber ring is used for a long time and ages, the redundant area will leak, allowing outside air to enter the tank, which may bring in harmful microorganisms and also affect the stability of the temperature in the tank.

[0016] 2. Yogurt contains a large number of probiotics, which will produce a large amount of gas during the reproduction process, including carbon dioxide, hydrogen, etc., which will increase the air pressure in the fermentation tank. When the air pressure is greater than the set value of the safety valve, the safety valve will open to release the pressure. When you need to remove the gland body, you need to press the pressure relief block first. The pressure relief block will press the limit pad and the sealing pad. When the sealing pad is separated from the gland shell, the pressure relief groove is connected with the interior of the pressure relief shell. At the same time, the transmission rod presses the pressure relief positioning piece to make the interior of the pressure relief shell connected with the interior of the fermentation tank, thereby achieving pressure relief of the gas inside the fermentation tank, releasing the gas generated by fermentation, and then disassembly, which improves the safety of the disassembly work.
