Description

Technical Field

[0001] This utility model is a tissue grinding device, belonging to the field of tissue grinding devices for filamentous fungi. Background Technology

[0002] When studying the internal substances of filamentous fungal cells, the cell walls must be broken first so that the target substance can be released from the cells. The process of grinding mycelium with liquid nitrogen involves placing the mycelium in a pre-cooled porcelain mortar, then adding liquid nitrogen. After being frozen by liquid nitrogen, the filamentous fungi need to be put into a grinder for grinding and pulverizing. The filamentous fungal tissue becomes hard and brittle after being cooled.

[0003] In the prior art, during the rotation of the grinding rod or grinding blade inside the grinder, friction occurs with the air, filamentous fungal tissue, or the inner wall of the grinder. This friction generates heat, which causes the temperature of the filamentous fungal tissue to rise, soften, and decrease in brittleness. Consequently, the fineness of the ground particles of the filamentous fungal tissue is reduced, thus lowering the quality of the grinding process.

[0004] In summary, this utility model provides a tissue grinding device to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a tissue grinding device that solves the problem mentioned in the background art: during the grinding process, frictional heat generated by the grinding structure causes the temperature of filamentous fungal tissue to rise, the tissue to soften, and its brittleness to decrease, thereby reducing the fineness of the grinding particles of filamentous fungal tissue and the quality of the grinding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tissue grinding device, comprising a base plate, support rods fixedly installed around the top of the base plate, a fixing plate installed between the top ends of the four support rods, fixing rods fixedly installed around the top of the fixing plate, a load-bearing plate installed between the top ends of the four fixing rods, a grinding vessel body fixedly installed at the top center of the fixing plate, an electric grinding mechanism fixedly installed at the bottom of the load-bearing plate, a lifting base embedded in the bottom of the inner wall of the grinding vessel body, a cooling structure embedded inside the grinding vessel body, and an opening for movement between the top and bottom of the load-bearing plate.

[0007] Furthermore, the electric grinding mechanism includes two electric lifting rods, which are respectively fixedly installed on both sides of the bottom of the load-bearing plate. A top cover is fixedly installed between the output ends of the two electric lifting rods. The bottom of the top cover is embedded in the top of the grinding vessel. A housing is fixedly installed on the top of the top cover and directly below the movable opening. A motor is fixedly installed inside the housing. A rotating shaft is fixedly installed on the output end of the motor. One end of the rotating shaft passes through the housing and the top cover in sequence and extends into the interior of the grinding vessel. A grinding blade is fixedly installed at the bottom end of the rotating shaft.

[0008] Furthermore, the lifting base includes an electric push rod and a bottom cover. The bottom cover is embedded in the bottom of the inner wall of the grinding vessel. A sealing ring is fixedly sleeved on the outer ring surface of the bottom cover. The electric push rod is fixedly installed on the top of the base plate and located directly below the bottom cover. The output end of the electric push rod passes through the fixed plate and the grinding vessel in sequence and extends to the bottom of the bottom cover.

[0009] Furthermore, the electric push rod is in contact with the grinding vessel body and the fixed plate.

[0010] Furthermore, the cooling structure includes a nitrogen tank, an air pump, and three annular gas chambers. The nitrogen tank is fixedly installed on one side of the top of the base plate, and the air pump is fixedly installed on one side of the bottom of the fixed plate. The three annular gas chambers are sequentially opened inside the grinding vessel from top to bottom. Each annular gas chamber has an air outlet on its inner ring surface, and one end of each air outlet extends to the inner wall of the grinding vessel.

[0011] Furthermore, the port of the air outlet is connected to a one-way air valve, the air delivery channel is connected to the annular air chamber, and the air inlet channel is connected to the annular air chamber.

[0012] The beneficial effects of this utility model are:

[0013] By starting the motor, the grinding blades are driven to rotate by the shaft, grinding and pulverizing the filamentous fungi inside the grinding vessel. At the same time, the cooling structure is activated to continuously supply nitrogen gas into the grinding vessel. During the grinding process, the high-speed rotation of the grinding blades generates friction and heat between itself and the filamentous fungi. The continuously supplied nitrogen gas can continuously cool the filamentous fungi, ensuring that the filamentous fungi can be continuously frozen into a solid state. The ground tissue particles are finer, effectively improving the quality of filamentous fungal tissue grinding and processing.

[0024] Please see Figure 2-4 The lifting base 7 includes an electric push rod 73 and a bottom cover 71. The electric push rod 73 is connected to an external power source and is equipped with a power control switch. The bottom cover 71 is embedded in the bottom of the inner wall of the grinding vessel 8. A sealing ring 72 is fixedly fitted on the outer ring surface of the bottom cover 71. The electric push rod 73 is fixedly installed on the top of the base plate 1 and located directly below the bottom cover 71. The output end of the electric push rod 73 passes through the fixing plate 3 and the grinding vessel 8 in sequence and extends to the bottom of the bottom cover 71. The electric push rod 73 is in contact with the grinding vessel 8 and the fixing plate 3. The outer diameter of the bottom cover 71, which is wrapped with the sealing ring 72, is equal to the inner diameter of the grinding vessel 8. The sealing ring 72 can improve the sealing between the bottom cover 71 and the inner wall of the grinding vessel 8 during the process of moving from bottom to top, and can also scrape the filamentous fungal tissue attached to the inner wall of the grinding vessel 8 from bottom to top.

[0025] Please see Figure 2-4The cooling structure 9 includes a nitrogen tank 91, an air pump 96, and three annular gas chambers 92. The nitrogen tank 91 is fixedly installed on one side of the top of the base plate 1, and the air pump 96 is fixedly installed on one side of the bottom of the fixing plate 3. The three annular gas chambers 92 are sequentially opened from top to bottom inside the grinding vessel body 8. Each annular gas chamber 92 has an air outlet 93 on its inner annular surface, and one end of each air outlet 93 extends to the inner wall of the grinding vessel body 8. An air supply channel 94 is opened inside the grinding vessel body 8 between every two annular gas chambers 92. The bottom of one of the annular gas chambers 92 is connected to an air inlet channel 95. The bottom end of the air inlet channel 95 extends to the bottom of the fixed plate 3. An exhaust pipe 97 is connected between the bottom end of the air inlet channel 95 and the outlet end of the air pump 96. An air inlet pipe 98 is connected between the air inlet end of the air pump 96 and the outlet end of the nitrogen tank 91. A one-way valve is connected to the port of the air outlet 93.

The gas inside the air outlet 93 can be transported to the grinding chamber of the grinding vessel 8 through the one-way valve, thereby cooling the entire grinding chamber of the grinding vessel 8.

[0026] Detailed implementation: By activating the retraction switch at the output end of the two electric lifting rods 61 inside the electric grinding mechanism 6, the top cover 62 is moved upward, thereby opening the grinding vessel 8. The filamentous fungi frozen by liquid nitrogen are placed inside the grinding vessel 8. Then, the extension switch at the output end of the two electric lifting rods 61 is activated, thereby moving the top cover 62 downward and embedding it into the top of the grinding vessel 8, thus closing the grinding vessel 8.

[0027] The motor 64 is started, driving the rotating shaft 65 to rotate. The rotating shaft 65 drives the grinding blade 66 to rotate, thereby grinding and pulverizing the filamentous fungi inside the grinding vessel 8. At the same time, the air pump 96 inside the cooling structure 9 is started, drawing nitrogen from the nitrogen tank 91 through the air inlet pipe 98 and evenly delivering the nitrogen to the inside of the grinding vessel 8 through the exhaust pipe 97, air inlet channel 95, two air supply channels 94, three annular air chambers 92 and multiple air outlets 93. The air pressure can automatically open the one-way air valve on the air outlet 93 to prevent nitrogen and filamentous fungal powder from flowing back into the air outlet 93. The nitrogen input into the grinding vessel 8 can continuously cool the grinding blade 66 and the filamentous fungi. During the grinding process, the high-speed rotation of the grinding blade 66 generates friction and heat between itself and the filamentous fungi. The continuously delivered nitrogen can continuously cool the filamentous fungi, ensuring that the filamentous fungi can be continuously frozen into a solid state. The ground tissue particles are finer, effectively improving the grinding quality of filamentous fungal tissue.

[0028] After grinding is complete, the output end retraction switch of the two electric lifting rods 61 can be activated to move the top cover 62 upward, opening the grinding vessel 8. After the electric grinding mechanism 6 can be completely removed from the inside of the grinding vessel 8, the output end extension switch of the electric push rod 73 inside the lifting base 7 can be activated to push the bottom cover 71 upward. The bottom cover 71 can push the filamentous fungal tissue particles inside the grinding vessel 8 from bottom to top. At the same time, the bottom cover 71 can scrape the particles adhering to the inner wall of the grinding vessel 8 from bottom to top through the sealing ring 72, effectively reducing the residual grinding particles inside the grinding vessel 8 and improving the sampling efficiency of the tissue grinding equipment.
