Description

Technical Field

[0001] The invention relates to the technical field of food engineering, in particular to a fermentation tank for acid material of snail powder. Background Art

[0002] Snail noodles are the most famous and popular rice noodle snack in Liuzhou City, Guangxi. Its fresh, sour, spicy, refreshing and hot characteristics quickly attracted food lovers from all over the country. Sour beans, radishes, bamboo shoots and sauerkraut are all traditional side dishes of snail noodles. These sour ingredients are all vegetable fermented products formed by lactic acid fermentation under low salt concentration conditions.

[0003] When it is necessary to ferment the snail noodle sour material, in order to prevent the sour material from browning, it is generally carried out in a sealed environment. However, when the sour material is placed in a tank and immersed in the ingredient water, foam is easily generated on the surface of the ingredient water during the fermentation process due to the evaporation of the sour material. The formed foam is difficult to clean in a sealed environment, and the beans or bamboo shoots may not be completely immersed in the water during the soaking process, which may cause partial browning of the sour beans, reducing the fermentation effect of the sour material. In addition, after the fermentation of the sour material is completed, the fermentation gas generally needs to be discharged, but the existing gas discharge is relatively scattered, resulting in the inability to discharge the gas in a unified manner, increasing the limitations of the gas purification work and reducing the air quality of the working environment.

The multiple groups of exhaust holes can be used to evenly absorb gas and foam. The exhaust pipes 56 with a stirring rod structure can be used to stir and mix the fermented acid material and the preparation liquid.

[0040] As a preferred solution of this embodiment: the air guide tube 55 is sleeve-connected with the rotary joint 54, and the air pump

[0041] The bottom of 53 is provided with an air extraction port extending to the inside of the air guide tube 55, so as to promote the axial rotation of the air guide tube 55 under the cooperation of the rotary joint 54 and maintain the normal operation of the air extraction work of the air extraction pump 53.

[0042] Embodiment 1, as shown in Figures 1-3, when the top cover 61 is lifted as a whole, the two groups of connected sleeves 42 can be driven to rise under the limit of the guide column 41, and the annular filter screen can be driven by the sleeve 42 to rise together and placed on the same horizontal plane of the water supply device 8. At this time, when the acid material is added, the water supply channel and the annular groove of the water supply device 8 can be used to cooperate to allow water to be evenly sprayed from multiple groups of water spray holes, and cold water can be sprinkled from the annular filter screen onto the surface of the fallen acid material, thereby allowing the cold water to pre-wet the surface of the acid material, and then the two groups of heating devices 7 are used to heat the immersed liquid to a specified temperature, thereby soaking and fermenting the acid material.

[0043] Embodiment 2, as Figure 2-4 As shown, after the acid material is fermented, the air pump 53 can be started, and the air guide pipe 55 and the air extraction pipe 56 can be connected to absorb the fermented gas inside the tank body 1. At the same time, under the structural connection of the drive motor 58 driving the gear set 57, the air guide pipe 55 and the two sets of air extraction pipes 56 are rotated to improve the extraction efficiency of the fermented gas inside the tank body 1, and the gas is uniformly circulated through the channels of the telescopic hose 52 and the exhaust pipe 51, so that the fermented gas can be easily discharged to the designated position for collection, which is convenient for direct gas purification and increases the environmental protection of the device. By starting the discharge valve, the fermented acid material in the tank body 1 can enter the screw feeder, so that the screw feeder can be used to send the acid material to the designated position for collection.

[0044] Embodiment 3, as shown in FIG. 1-3, can through the temperature sensor on the top of the tank body 1 and the acidity detector installed on the mounting seat 45, can intelligently monitor the temperature and acidity of the nitrite, nitrate, hydrogen sulfide, and formaldehyde fermented inside the tank body 1, improve the accuracy of the internal liquid mixing, and can automatically set the fermentation time and timing function through the control of the timer, so as to automatically add beans, radishes and bamboo shoots, so that the fermentation quality of the fermented sour bamboo shoots, sour radishes, sauerkraut and sour beans is further improved.

[0045] Working principle: When the device is in use, the control panel 3 can be used to start the servo motor 66 to drive the screw 65 to rotate. As the screw 65 rotates, the internal threaded tube 63 is forced to rise, and the rise of the internal threaded tube 63 drives the connected top cover 61 to rise, and the sealing engagement between the top cover 61 and the through-port 62 is cancelled. At this time, the acid material to be fermented can be put into the tank body 1, and the preparation liquid is poured and heated through the water supply device 8, so that the acid material is immersed in the preparation liquid, and then the top cover 61 is reset and re-embedded into the through-port 62, so that the tank body 1 is lifted.

[0046] The body 1 is sealed inside, so that the acid material can be sealed and fermented;

[0047] When the sour material is fermented, foam will be generated on the surface. At this time, the mounting seat 45 and the two sets of sleeves 43 can be driven to descend by starting the lifting cylinder 44. During this period, the elastic stretching of the telescopic hose 52 can be used to automatically extend the mounting seat 45 when it descends, so that the mounting seat 45 can be stably lifted and lowered under the limit of the two sets of sleeves 43 and the sleeve 42, and then the two sets of air extraction pipes 56 are lowered to a height close to the soaking water. At this time, the driving motor 58 can be started to drive the gear set 57 to cooperate and force the air guide pipe 55 to rotate, and the connection of the rotary joint 54 can be used to drive the air guide pipe 55 to drive the two sets of air extraction pipes 56 to rotate. At this time, the air pump 53 can be started, and the air guide pipe 55 and the air extraction pipe 56 are used as the air extraction space, so that the rotation of the air extraction pipe 56 can be used to evenly extract the foam on the surface of the prepared liquid, and part of the gas is discharged from the telescopic hose 52 and the exhaust pipe 51, thereby improving the fermentation effect of the snail powder sour material.

[0048] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
