As shown in fig. 1, the ultrahigh pressure device for driving a piston by using a liquid medium according to the embodiment of the present invention mainly includes an ultrahigh pressure cylinder 1 and a piston 2. The piston 2 is positioned in the ultrahigh pressure cylinder body 1, and the ultrahigh pressure cylinder body 1 is divided into a pressurizing cavity 11 and a material cavity 12 which are isolated from each other by the piston 2. The pressurizing cavity 11 is filled with pressurized liquid, and the piston 12 is driven by the pressurized liquid to move in the ultrahigh pressure cylinder 1 so as to apply ultrahigh pressure to the material in the material cavity 12.
The ultrahigh pressure pressurizing device for driving the piston by using the liquid medium can be applied to ultrahigh pressure sterilization of food, and when the ultrahigh pressure pressurizing device is used, the liquid food is directly introduced into the material cavity 12 and the material cavity 12 is sealed. The soft container for containing liquid food is not needed, the utilization rate of the ultrahigh pressure container is effectively improved, and the production requirement of the flow-line automatic ultrahigh pressure sterilization of the liquid material without manual intervention in the fully-closed middle is met. Before and after the ultra-high pressure sterilization, the cleaning and the disinfection of the rigid body characteristic material cavity 12 of the ultra-high pressure cylinder body 1 and the piston 2 are more convenient.
In an alternative embodiment, the ultrahigh-pressure pressurizing device for driving the piston by using the liquid medium according to the embodiment of the invention further comprises a liquid supply device. Specifically, the pressurizing chamber 11 is connected to the liquid supply device, and pressurized liquid is supplied from the liquid supply device. Because liquid is conveyed by adopting a pipeline, the liquid supply device can be flexibly arranged according to the actual site space, so that the space compatibility of the installation of the whole ultrahigh pressure pressurization device is stronger.
Specifically, the pressurizing cavity 11 is provided with a first liquid inlet and a first liquid outlet in cooperation with the inlet and the outlet of the pressurized liquid. As shown in fig. 1, the liquid supply device includes a reservoir 31, a pressure intensifier 31, and a shutoff valve 32. Wherein the liquid reservoir 31 holds pressurized liquid for pressurizing the pressurizing chamber 11, and the liquid reservoir 31 has a second liquid outlet and a second liquid inlet. The pressure booster 32 is connected between the second liquid outlet and the first liquid inlet to boost the pressure of the pressurized liquid output from the liquid reservoir 31 and to introduce the pressurized liquid into the pressurizing chamber 11. The shutoff valve 33 is connected between the first liquid outlet and the second liquid inlet, and is shut off when the pressurizing chamber 11 is pressurized and opened after the pressurization is completed. The stop valve 33 is stopped when the pressurizing chamber 11 is pressurized, and can ensure that the pressurizing chamber 11 does not return to the liquid reservoir 31 when pressurized, thereby reducing the internal pressure of the ultra-high pressure cylinder 1, and is opened after pressurization is completed, so that the pressurized liquid returns to the liquid reservoir 31, thereby releasing the internal pressure of the ultra-high pressure cylinder 1.
In an alternative embodiment, as shown in fig. 1, the liquid supply device further comprises a check valve 34, the check valve 34 being connected between the pressure intensifier 32 and the first liquid inlet of the pressurizing chamber 11, so that the pressurized liquid flows from the pressure intensifier 32 to the pressurizing chamber 11 only, and the pressurized liquid in the pressurizing chamber 11 is prevented from flowing back to the pressure intensifier 32. In the differential high pressure sterilization process by applying differential high pressure to the pressurization cavity 11, the leakage of the pressurization liquid in the ultrahigh pressure state of the pressurization cavity 11 is realized by the cooperation of the stop valve 33 and the one-way valve 34, and the pressure stability in the ultrahigh pressure cylinder body 1 is ensured.

In an alternative embodiment, as shown in fig. 1, the liquid supply device further comprises a flow switch 36, the flow switch 36 being connected between the shut-off valve 33 and the second inlet of the reservoir 31 for issuing an alarm signal when the flow of pressurized liquid therethrough exceeds a set threshold. The addition of the flow switch 36 prevents the downstream pipe and the reservoir 31 from being impacted by an excessive flow of pressurized fluid. In an alternative embodiment, the host computer may be adapted to receive an alarm signal from the flow switch 36 and, upon receipt of the alarm signal, control the state of the shut-off valve 33 to reduce the flow of pressurized liquid.
In an alternative embodiment, as shown in fig. 1, the liquid supply apparatus further includes a liquid amount detector 37, and the liquid amount detector 37 is mounted to the reservoir 31 to detect a reservoir amount of the pressurized liquid in the reservoir 31.
In alternative embodiments, the stock solution may be mass, volume, or the like. When mass is used as the liquid storage amount, the volume of the pressurized liquid can be calculated from the density of the pressurized liquid.
By adopting the ultrahigh-pressure pressurizing device for driving the piston by using the liquid medium, the liquid food which is pretreated can be input into the material cavity through the material conveying pipeline connected with the material cavity, then the ultrahigh-pressure sterilization process (such as continuous pulse type ultrahigh-pressure sterilization) is executed, and after the ultrahigh-pressure sterilization is finished, the sterilized liquid food is canned or subsequently processed through the material conveying pipeline connected with the material cavity, so that the final product is formed. The whole process only needs to carry out canning once, thereby saving food processing steps and simplifying the food production process.

step 1, connecting the pressurizing cavity to an external liquid supply device, and recording the amount of pressurized liquid in the liquid supply device as initial liquid amount when the piston is at a known initial position;
and 3, determining the position of the piston after the pressurized liquid is introduced into the pressurizing cavity according to the liquid amount, the initial liquid amount and the initial position of the piston.

and determining the position of the piston after the pressurized liquid is introduced according to the moving distance of the piston in the ultrahigh pressure cylinder and the initial position of the piston.
In an alternative embodiment, both the initial and varying amounts of liquid are the mass of the pressurized liquid. Further, the amount of pressurized liquid introduced is the introduction mass of the pressurized liquid, and in step 32, the volume of the pressurized liquid introduced into the pressurized chamber can be calculated in combination with the density of the pressurized liquid.
In alternative embodiments, the pressurized liquid is water or oil.
In addition, in an optional embodiment, when the ultrahigh pressure sterilization treatment is not performed, the position correction and adjustment of the piston in the ultrahigh pressure cylinder body can be assisted by introducing pressurized liquid into the pressurizing cavity and introducing gas into the material cavity, and the gas introduced into the material cavity can be nitrogen or inert gas which does not react with liquid food, so that the pollution to the liquid food added into the material cavity can be avoided.
