[0047] In the above description, the pressurizing mechanism 4 pressurizes the seabuckthorn raw material to 100-300 MPa, and then the material is pushed into the hard alloy alternating cavity tank 5. The tank body of the hard alloy alternating cavity tank 5 is provided with a micron-level channel array. The high-pressure material forms a super-speed micro-jet beam of 300-400 m / s in the channel array. Through the synergistic effect of shear force, cavitation effect and jet collision, the cell wall is instantaneously broken and the active ingredients are released.

The refrigerant inlet connecting pipe 21 and the refrigerant outlet connecting pipe 22 are both arranged on the outer wall of the barrel body 2 and communicate with the heat exchange cavity 23 opened on the side wall of the barrel body 2, forming the temperature control system.

[0049] In the above description, the heat exchanger 3 is communicated with the heat exchange cavity 23 through the reflux pipe 9 and the cooling pipe 10, so that when the barrel body 2 is working, the heat exchanger 3 can heat or cool the refrigerant according to the set temperature, and at the same time, the reflux pipe 9 and the cooling pipe 10 form a passage for guiding the refrigerant into the heat exchange cavity 23 for heat exchange, so as to control the temperature in the cavity of the barrel body 2, avoid the thermal degradation of heat-sensitive components of seabuckthorn, and ensure the stability of the processing process.

[0050] It should be noted that in order to ensure good heat conduction effect, the barrel body 2 is made of copper or copper alloy material.

[0051] Specifically, as shown in Figure 1 and Figure 2 , a control pump 7 is further arranged on the reflux pipe 9, which is used to control the flow speed of the refrigerant by controlling the control pump 7 during use, so as to adjust the heat exchange effect.

[0052] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the inlet end of the barrel 2 is provided with a one-way valve 8, which is connected to the storage barrel 6 through a pipeline for realizing the one-way input of seabuckthorn raw materials into the inner cavity of the barrel 2; the pressurized conveying end of the barrel 2 is connected to the hard alloy interactive cavity tank 5, and the pipeline is provided with an overflow valve 11 for controlling the one-way outflow of high-pressure seabuckthorn liquid. When the pressure in the barrel 2 exceeds the set value of the overflow valve 11, the overflow valve 11 is automatically opened to ensure that the material can only enter the interactive cavity tank 5 along the preset path, thereby forming a closed fluid passage.

[0053] In the above description, during the reciprocating movement of the multi-stage soft sealing plug 43, the system realizes automatic feeding and discharging through pressure changes: when the multi-stage soft sealing plug 43 returns to the left, the inner cavity of the barrel 2 forms a negative pressure, triggering the opening of the inlet end one-way valve 8, and the seabuckthorn raw materials in the storage barrel 6 are automatically supplemented into the barrel 2; when the multi-stage soft sealing plug 43 advances to the right, the pressure in the barrel 2 rises suddenly, and at this time the pressurized conveying end one-way valve 8 remains closed, until the pressure breaks through the threshold of the overflow valve 11, and then the high-pressure seabuckthorn liquid is injected into the hard alloy interactive cavity tank 5 at high speed through the one-way valve 8, and the ultramicro jet effect is generated by cooperating with the microchannel structure in the interactive cavity, thereby completing the cell wall breaking and homogenization treatment.

This structure realizes one-way sealing through the pre-tightening force of the spring, and the design of the flow guide hole 85 can balance the fluid resistance and sealing performance.

[0055] In the above description, under normal conditions, the spring 83 drives the ball valve core 82 to form a linear seal with the liquid inlet side wall of the valve cavity 84, blocking the fluid passage; when a negative pressure is generated on the side of the valve cavity 84 close to the stop plate 86, the pressure difference between the inlet and outlet overcomes the pre-tightening force of the spring 83, and pushes the ball valve core 82 to displace towards the stop plate 86, while the spring 83 is compressed and the liquid inlet passage is opened. At this time, the seabuckthorn liquid enters the valve cavity 84 through the flow guide hole 85 and pushes open the ball valve core 82 to form a one-way flow, and this process realizes accurate control of pressure response through the linear relationship between spring stiffness and valve core displacement.

[0056] In a preferred embodiment, as shown in the drawings, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the pressure increasing mechanism 4 includes a plunger pump 41 and a plunger 43, the plunger pump 41 is fixed outside the cylinder body 2 through a support, the driving end of the plunger pump 41 is connected with a piston 42 and extends into the inner cavity of the cylinder body 2 to form a reciprocating pair. A multi-stage soft sealing plug 43 is also arranged at the end of the piston 42, the multi-stage soft sealing plug 43 adopts a multi-layer composite elastomer structure and forms a dynamic seal with the inner wall of the cylinder body 2 through interference fit.

[0057] In the above description, under the reciprocating drive of the plunger pump 41, the multi-stage soft sealing plug 43 performs high-frequency reciprocating motion along the axis of the cylinder body 2 to periodically compress the sea buckthorn liquid. The soft sealing structure replaces the traditional rigid sealing through elastic deformation, effectively reduces the contact stress of the sealing interface, and maintains the function of the lubricating oil film of the sealing lip to effectively reduce the friction coefficient. This design not only effectively reduces the noise of the equipment during operation, but also effectively suppresses the generation of metal friction heat, and cooperates with the temperature control system to control the temperature rise of the inner wall of the cylinder body 2 within ±2℃, thereby significantly improving the retention rate of heat-sensitive components.

[0058] Specifically, as shown in the figure, Figure 3 A guide plate 24 is also flange-mounted on the side of the cylinder body 2 close to the plunger pump 41, the guide plate 24 is in sliding connection with the piston 42 to guide the movement of the piston 42.

[0059] Specifically, as shown in the figure, Figure 5 The multi-stage soft sealing plug 43 includes a center tube, the center tube is fixed to the end of the piston 42 through threaded connection to form a detachable sealing assembly. A plurality of annular embedding grooves 44 are equidistantly opened on the outer wall of the center tube along the axis, and a flexible sealing ring 45 is embedded in each embedding groove 44. A composite sealing structure is constructed through the multi-stage stepped arrangement of the plurality of flexible sealing rings 45, and the spacing between adjacent sealing rings 45 forms a self-adaptive compensation mechanism with the roughness of the inner wall of the cylinder body 2.

[0060] In the above description, the flexible sealing ring 45 adopts a fluororubber-based composite material and forms an interference fit with the inner wall of the cylinder body 2 to compensate for the processing error and reciprocating wear through elastic deformation of the material. This structure makes the contact stress distribution of the sealing interface uniform, and the stepped sealing lip design of the flexible sealing ring 45 can automatically compensate for the wear amount, and still maintains the dynamic sealing performance under an extreme pressure of 300MPa, while effectively reducing the friction power consumption, and cooperates with the temperature control system to realize stable operation of the sealing interface at a temperature of ≤60℃.
