A pressure cylinder 8 for placing the Chinese herbal medicine pieces to be sterilized is fixed on the side of the pressure block 72 facing away from the cylinder 7. A pressure member 9 for applying pressure to the pressure cylinder 5 is provided on the support plate 2. A water supply mechanism 10 for supplying water to the pressure cylinder 5 is provided on the top plate 3. The Chinese herbal medicine pieces in the gauze bag are placed in the pressure cylinder 8, and the pressure member 9 cooperates with the pressure block 72 to seal the pressure cylinder 5. After the pressure cylinder 5 is filled with water by the water supply mechanism 10, the Chinese herbal medicine pieces in the pressure cylinder 8 will be immersed in the water in the pressure cylinder 5, and then the pressure member 9 will supply water to the pressure cylinder 5. The block 72 moves and compresses the water filled in the pressurizing cylinder 5, so that the water in the pressure-bearing cylinder 8 is applied to the Chinese herbal medicine slices at high pressure, so that the microorganisms on the surface of the Chinese herbal medicine slices are inactivated under the high water pressure environment, and the effect of sterilizing the Chinese herbal medicine slices is achieved while maintaining the original flavor, color and nutritional components of the Chinese herbal medicine slices as much as possible; the pressure-bearing cylinder 8 is composed of an outer cylinder 81 and an inner cylinder 82, the outer cylinder 81 is fixedly connected to the pressure-bearing block 72, a through port is opened on the top of the outer cylinder 81, a drain valve 811 is installed at the bottom of the outer cylinder 81, the inner cylinder 82 is sealed and rotatably assembled in the outer cylinder 81, a filter plate 821 is provided on one side of the cylinder wall of the inner cylinder 82, and the inner cylinder A discharge port is provided on the side of the cylinder wall 82 away from the filter plate 821. The discharge port of the inner cylinder 82 is smaller than the through port of the outer cylinder 81. Sealing rings 84 are provided at both ends of the rotating connection between the outer cylinder 81 and the inner cylinder 82 to improve the sealing performance. A hard pipe 83 is fixed to one side of the inner cylinder 82. A motor 85 is provided in the pressure block 72. The output shaft of the motor 85 passes through the pressure block 72 and is connected to the rotation center of the inner cylinder 82. The discharge port of the inner cylinder 82 is aligned with the through port of the outer cylinder 81, which is convenient for placing Chinese herbal medicines. After the inner cylinder 82 is rotated to the point where the filter plate 821 and the through port of the outer cylinder 81 are aligned, the Chinese herbal medicines are limited in the inner cylinder 82 for high-pressure sterilization.

[0028] like Figure 3 and Figure 6 As shown, a solenoid valve 51 is installed on the top of the cylinder wall of the pressure cylinder 5. The solenoid valve 51 is used to discharge the gas in the pressure cylinder 5. A fixing ring 52 is fixedly connected to the side of the inner wall of the pressure cylinder 5 close to the cylinder 7. The fixing ring 52 is in contact with the pressure block 72. The piston rod of the cylinder 7 passes through the fixing ring 52 and is connected to the pressure block 72. The fixing ring 52 is used to limit and bear the water pressure on the pressure block 72 to prevent the water pressure from directly acting on the cylinder 7 through the pressure block 72 and causing damage to the cylinder 7.

[0029] As Figure 1 and Figure 3 shown, the pressing member 9 includes a second hydraulic cylinder 91 and a pressing block 92. The second hydraulic cylinder 91 is fixedly installed on the support plate 2. The piston rod of the second hydraulic cylinder 91 faces the pressure cylinder 5 and fixedly installs the pressing block 92. The pressing block 92 fits against the inner wall of the pressure cylinder 5. The pressing block 92 and the pressure cylinder 5 are in sealing and sliding fit. A sealed chamber for high-water-pressure sterilization is formed between the pressure-bearing block 72 and the pressing block 92 in the pressure cylinder 5. The hard pipe 83 on the inner cylinder 82 is hermetically and slidably inserted into the pressing block 92. The pressing block 92 can be separated from the pressure cylinder 5 and the hard pipe 83. The second hydraulic cylinder 91 drives the pressing block 92 to move towards the pressure-bearing block 72 in the pressure cylinder 5, thereby compressing the water filled in the pressure cylinder 5, so that the high-pressure water sterilizes the Chinese herbal medicine pieces in the inner cylinder 82.

[0030] As Figure 1 and Figure 7 shown, the water supply mechanism 10 includes a water cylinder 101, a water delivery pipe 102 and a liquid pump 103. The water cylinder 101 is fixedly arranged on the top plate 3. The water cylinder 101 is communicated with the pressure cylinder 5 through the water delivery pipe 102. A liquid pump 103 is assembled in the water cylinder 101. One end of the water delivery pipe 102 is communicated with the liquid pump 103, and the other end of the water delivery pipe 102 is communicated with the bottom of the inner wall of the pressure cylinder 5. The water delivery pipe 102 is located between the pressure-bearing block 72 and the pressing block 92 in the pressure cylinder 5. During sterilization, the liquid pump 103 can inject the water in the water cylinder 101 into the pressure cylinder 5 through the water delivery pipe 102. After sterilization is completed, the liquid pump 103 can pump the water in the pressure cylinder 5 back into the water cylinder 101.

[0031] When using this device to sterilize Chinese herbal pieces, activate the hydraulic cylinder 6 on the upper and lower guide rails 4. The hydraulic cylinder 6 drives the pressure cylinder 5 on the mounting ring 61 to move along the guide rail 4, so that the pressure cylinder 5 is displaced to the side of the guide rail 4 away from the support plate 2. At this time, the pressure cylinder 5 and the pressure block 92 are separated. Then activate the cylinder 7. The cylinder 7 drives the pressure-bearing cylinder 8 on the pressure-bearing block 72 to be pushed out of the pressure cylinder 5. Then pack the Chinese herbal pieces to be sterilized into a gauze bag and place them through the position where the through port at the top of the outer cylinder 81 of the pressure-bearing cylinder 8 is aligned with the discharge port of the inner cylinder 82. After loading a certain amount of Chinese herbal pieces into the pressure-bearing cylinder 8, activate the hydraulic cylinder 6 and the cylinder 7 again. The pressure cylinder 5 moves back to the initial position. At this time, the pressure block 92 slides into the pressure cylinder 5 again in a sealed manner. The precise cooperation between the pressure-bearing block 72 on the inner wall of the pressure cylinder 5 and the pressure block 92 forms a completely sealed sterilization chamber. At the same time, the pressure-bearing cylinder 8 returns to the initial position state, and the pressure-bearing block 72 contacts the fixed ring 52 in the pressure cylinder 5. Then activate the motor 85 to drive the inner cylinder 82 in the outer cylinder 81 to rotate, so that the filter plate 821 on the cylinder wall of the inner cylinder 82 is aligned with the through port of the outer cylinder 81. At this time, the Chinese herbal pieces are enclosed inside the inner cylinder 82, and the drain valve 811 is in the state of the pipe wall. The pores of the filter plate 821 allow water to penetrate but block the escape of materials. When sterilizing, the liquid pump 103 of the water supply mechanism 10 starts to work. The liquid pump 103 injects the water in the water cylinder 101 into the pressure cylinder 5 through the water delivery pipe 102. The water flow gradually rises from the bottom of the pressure cylinder 5 until it completely submerges the Chinese herbal pieces in the pressure-bearing cylinder 8. During the process of adding water, synchronously open the solenoid valve 51 at the top of the pressure cylinder 5, and gradually discharge the air in the chamber when the pressure cylinder 5 is filled with water, so as to avoid the influence of gas on the uniformity of water pressure transmission. When the water flow completely fills the chamber between the pressure-bearing block 72 and the pressure block 92 in the pressure cylinder 5, close the solenoid valve 51 and the liquid pump 103 to make the pressure cylinder 5 form a sealed state filled with water. Finally, activate the hydraulic cylinder 91. The hydraulic cylinder 91 pushes the pressure block 92 towards the pressure-bearing block 72. At this time, the hard pipe 83 will be synchronously and sealed into the pressure-bearing block 72. The pressure block 92 exerts a continuous pressure on the water body in the sealed chamber, resulting in a rapid increase in water pressure to the preset high-pressure state. The high-pressure water uniformly penetrates through the pores of the filter plate 821 of the inner cylinder 82 to the surface of the Chinese herbal pieces in the gauze bag. The powerful hydrostatic pressure directly acts on the microbial cell membrane, destroys its structural integrity, causes the leakage of cell contents and inactivates them, and maintains the Chinese herbal pieces under high hydrostatic pressure for a period of time to fully sterilize them.

[0032] Example 2: On the basis of Example 1, as Figure 2 、 Figure 3 and Figure 6As shown in the figure, a negative pressure mechanism 11 is provided on the support plate 2. The negative pressure mechanism 11 includes a vacuum pump 111, a hose 112, and a connection valve 113. The vacuum pump 111 is fixedly assembled on the support plate 2 near the pressure cylinder 5. The vacuum pump 111 is communicated with the hose 112. The hose 112 is embedded through the pressing block 92. The pipe end of the hose 112 is communicated to the connection part of the pressing block 92 and the hard pipe 83. A connection valve 113 is installed at the connection part of the inner cylinder 82 and the hard pipe 83. After the water in the pressure cylinder 8 is discharged through the drain valve 811, when the feeding port of the inner cylinder 82 and the filter plate 821 are rotated so that they no longer align with the through port of the outer cylinder 81, the pressure cylinder 8 is in a sealed state. The vacuum pump 111 is used to pump air into the pressure cylinder 8, so that the sealed pressure cylinder 8 is gradually sucked into a negative pressure, and the drying rate of the traditional Chinese medicine decoction pieces in the pressure cylinder 8 under the negative pressure state is increased.

[0033] As Figure 8 shown in the figure, an ultraviolet lamp 12 is fixedly installed on the inner wall of the inner cylinder 82 of the pressure cylinder 8 through a clamping seat 121. The ultraviolet lamp 12 is made of a material resistant to high pressure. The ultraviolet rays generated by the ultraviolet lamp 12 are used to further kill microorganisms such as bacteria and molds on the surface of the traditional Chinese medicine decoction pieces, and improve the sterilization effect on the traditional Chinese medicine decoction pieces.

[0034] As Figure 9 shown in the figure, a microwave generator 14 is installed on the inner wall of the cylinder body of the pressure cylinder 5. There are no less than two microwave generators 14, which are distributed around the outer cylinder 81 of the pressure cylinder 8. The microwave generator 14 is used to accelerate the drying of the traditional Chinese medicine decoction pieces after high-pressure sterilization. Under the condition that the pressure cylinder 8 is pumped into a negative pressure by the cooperation of the negative pressure mechanism 11, the sterilized traditional Chinese medicine decoction pieces can be efficiently dried.

[0035] As Figure 8 and Figure 9 shown in the figure, a temperature and humidity sensor 13 is assembled on the inner wall of the inner cylinder 82 of the pressure cylinder 8. The temperature and humidity sensor 13 is used to monitor the temperature and humidity changes in the pressure cylinder 8 in real time. A digital display controller 15 is assembled on the outer wall of the outer cylinder 81 of the pressure cylinder 5. The temperature and humidity sensor 13 and the digital display controller 15 are electrically connected. The digital display controller 15 is used to control the whole sterilization device and display the monitoring data on the temperature and humidity sensor 13, so as to facilitate the user to control the device and understand the drying situation of the traditional Chinese medicine decoction pieces.

[0036] After the high-hydrostatic-pressure sterilization is completed, the hydraulic cylinder II 91 controls the pressing block 92 to slowly reset, releasing the high-pressure environment in the chamber. At the same time, the liquid pump 103 is activated, and the liquid pump 103 operates in reverse to pump the water in the pressure cylinder 5 back to the water cylinder 101 for storage. Then, the drain valve 811 and the solenoid valve 51 are opened. When the water level in the pressure cylinder 5 is lower than the pressure-bearing cylinder 8, the water in the pressure-bearing cylinder 8 will also flow into the pressure cylinder 5 through the drain valve 811. Under the action of the liquid pump 103, it is finally gradually pumped back into the water cylinder 101 through the water delivery pipe 102. After the pumping is completed, the liquid pump 103 is turned off. Subsequently, the motor 85 drives the inner cylinder 82 to rotate a certain angle, so that the discharge port of the inner cylinder 82 and the filter plate 821 both deviate from the position of the through-port of the outer cylinder 81. At this time, a completely sealed space is formed between the inner cylinder 82 and the outer cylinder 81 of the pressure-bearing cylinder 8. Then, the vacuum pump 111 is activated, and the vacuum pump 111 continuously sucks the inside of the pressure-bearing cylinder 8, gradually reducing the air pressure in the cylinder to a negative pressure state. Finally, the ultraviolet lamp 12 and the microwave generator 14 are activated. The ultraviolet lamp 12 can release ultraviolet light of a specific wavelength, causing irreversible damage to the genetic material of microorganisms, so that the traditional Chinese medicine pieces after high-pressure sterilization achieve a double sterilization effect under the action of ultraviolet light. The microwave emitted by the microwave generator 14 can penetrate the pressure-bearing cylinder 8 and reach the traditional Chinese medicine piece material, exciting the high-frequency vibration of water molecules in the traditional Chinese medicine pieces to generate heat energy, realizing uniform drying from the inside to the outside. In a negative pressure environment, a pressure gradient is formed between the inside of the traditional Chinese medicine pieces and the surrounding environment, thereby promoting the rapid evaporation of water. During the entire drying process, the data inside the cylinder is continuously collected by the temperature and humidity sensor 13, and the digital display controller 15 automatically adjusts the power of the vacuum pump 111, the microwave intensity, and the start and stop of the ultraviolet light according to the preset threshold to ensure the balance between the drying efficiency and the quality of the traditional Chinese medicine pieces. When the temperature and humidity sensor 13 detects that the humidity reaches the safe storage standard, the digital display controller 15 controls the vacuum pump 111, the ultraviolet lamp 12, and the microwave generator 14 to stop operating. Subsequently, the motor 85 drives the inner cylinder 82 to rotate and reset until the discharge port is aligned with the through-port. Then, through the cooperation of the hydraulic cylinder I 6 and the cylinder 7, the pressure-bearing cylinder 8 is pushed out of the pressure cylinder 5, and the operator can take out the dried and sterile traditional Chinese medicine pieces that meet the standards in the inner cylinder 82 of the pressure-bearing cylinder 8.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
