[0002] Cornus products refer to various types of Cornus products obtained by processing and preparing Cornus, including Cornus sauce, Cornus powder, Cornus oil, etc. Cornus products are widely used in the food industry.

[0003] During the processing of Cornus officinalis products, since Cornus officinalis itself is rich in nutrients and moisture, it can easily become a breeding ground for bacteria and other microorganisms. Contamination by microorganisms will not only lead to a decline in the quality of Cornus officinalis products, but may also pose potential risks to consumers' health.

[0004] Traditional methods for sterilizing cornus officinalis products mainly include heat treatment, chemical sterilization and radiation sterilization. However, these sterilization methods have some problems to varying degrees. First, heat treatment may cause quality loss of cornus officinalis products, such as loss of color, taste and nutrients; chemical sterilization has the problem of residues, which may have a negative impact on human health; and radiation sterilization is subject to public concerns about radiation safety and is also restricted by regulations and supervision.

[0005] Therefore, an efficient and safe sterilization method for cornus products is needed to solve the above problems. As an emerging non-thermal sterilization method, ultrahigh pressure technology has many advantages. Ultrahigh pressure technology can apply high pressure and pulsed electric field in a shorter time to effectively kill microorganisms. Compared with traditional sterilization methods, ultrahigh pressure technology can retain more nutrients and original quality characteristics in cornus products. In addition, ultrahigh pressure technology is environmentally friendly and does not produce pollutants and residues.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The control unit 4 is used to control the operation of the ultra-high voltage device 2 and the pulse electric field device 3 .

[0038] It should be noted that the upper and bottom parts of the sterilization chamber 1 should also be provided with a feed port and a discharge port (not shown in the figure) respectively, which are used to load the Cornus officinalis products to be sterilized into the sterilization chamber 1 and take out the sterilized Cornus officinalis products from the sterilization chamber 1 respectively.

[0039] In addition, safety protection devices (not shown in the figure) are provided outside the ultra-high voltage device 2 and the pulse electric field device 3 to ensure the safety of operators.

[0040] In the present utility model, the ultra-high pressure device 2 includes:

[0041] A high pressure container 5, used for carrying gas;

[0042] The ultra-high pressure pump 6 is connected to the high pressure container 5 and the sterilization chamber 1 through pressure-resistant pipes, and is used to extract gas from the high pressure container 5 and pressurize the gas into ultra-high pressure gas before inputting it into the sterilization chamber 1;

[0043] The pressure sensor 7 is electrically connected to the control unit 4 , and is used to detect pressure data at the output side of the ultra-high pressure pump 6 , and feed the detected pressure data back to the control unit 4 .

[0044] Specifically, the gas is selected from one of air, nitrogen, carbon dioxide, oxygen and inert gas, and the pressure of the ultra-high pressure gas is 200-600MPa.

[0045] In the present utility model, the pulse electric field device 3 includes:

[0046] A pair of electrodes 8 and 9 are respectively disposed at the top and bottom of the sterilization chamber 1 and are used to generate a pulsed electric field;

[0047] The high voltage power supply 10 is used to provide the required high voltage to the pair of electrodes 8 and 9.

[0048] Specifically, the pair of electrodes 8 and 9 are selected from one of stainless steel electrodes, copper electrodes, aluminum electrodes, platinum electrodes, conductive polymer electrodes and carbon electrodes, and the frequency of the pulse electric field generated by the pair of electrodes 8 and 9 is 10-100 KHz.

[0049] In the present invention, the control unit 4 has a human-machine interactive interface for setting sterilization parameters, including ultra-high pressure value, pulse electric field frequency value and sterilization time, etc., to meet the sterilization requirements of different types and specifications of Cornus officinalis products.

[0050] In the present invention, a sterilization sensor 11 electrically connected to the control unit 4 is provided inside the sterilization chamber 1 for monitoring the degree of sterilization of the cornus officinalis product.

[0051] Specifically, the sterilization sensor 11 is a microbial counter or a pH sensor.

[0052] When a microbial counter is selected, the number of microorganisms in the sterilization chamber 1 can be directly measured; when a pH sensor is selected, the change of pH value during the sterilization process can be detected.

[0053] In the utility model, a pressure relief pipe 12 communicating with the interior of the sterilization chamber 1 is connected to one side of the upper part thereof, and a pressure relief valve 13 is installed in the pressure relief pipe 12. Thus, by opening the pressure relief valve 13, the ultra-high pressure gas can be discharged, that is, the ultra-high pressure in the sterilization chamber 1 can be relieved.

[0054] In the utility model, the sterilization chamber 1 is a box-shaped structure made of pressure-resistant material to ensure the safety and stability of the equipment, and has a suitable volume to accommodate various types of Cornus officinalis products and maintain the uniformity of the sterilization effect.

[0055] The utility model is further described below in conjunction with the accompanying drawings:

[0056] When in use, the Cornus officinalis products to be sterilized are placed in the sterilization chamber 1, and the sterilization parameters are set through the human-machine interface of the control unit 4, including the ultra-high pressure value, the frequency value of the pulse electric field and the sterilization time.

[0057] Then, start the sterilization equipment.

[0058] In this process, a pulse electric field and ultra-high pressure are applied to the sterilization chamber 1 to kill microorganisms in the cornus officinalis product.

[0059] Specifically, a pulse electric field is generated by a pair of electrodes 8 and 9, so that the microorganisms are killed by the electric field. At the same time, the ultra-high pressure pump 6 extracts the gas in the high-pressure container 5, pressurizes the gas into ultra-high pressure gas, and then inputs it into the sterilization chamber 1, generating an ultra-high pressure suitable for sterilizing cornus products.

[0060] The pressure sensor 7 detects the pressure data on the output side of the ultra-high pressure pump 6 in real time, and feeds back the detected pressure data to the control unit 4. When the pressure value on the output side of the ultra-high pressure pump 6 reaches the set ultra-high pressure value, the control unit 4 sends a control instruction to the ultra-high pressure pump 6, and the ultra-high pressure pump 6 stops working.

[0061] In addition, the sterilization sensor 11 monitors the degree of sterilization of the cornus officinalis products in the sterilization chamber 1 in real time. When the preset sterilization standard is reached, a signal is sent to the control unit 4, and the control unit 4 cuts off the power supply circuit of a pair of electrodes and 8, 9 to stop the sterilization process.

[0062] It should be noted that, according to actual needs, various components of the utility model can be optimized and improved. For example, the distance and shape between the pair of electrodes 8 and 9 can be adjusted to adapt to cornus products of different sizes and shapes. The control unit 4 can set sterilization parameters such as sterilization time through its human-machine interface, which is convenient for operators to set the sterilization time. The selection and setting of the sterilization sensor 11 should take into account the sterilization requirements of different microorganisms.

[0063] The utility model has the characteristics of being fast, efficient, and environmentally friendly, and has broad application prospects in the field of food sterilization. It can be widely used in the production and processing of cornus products, such as food processing plants, sauce production companies, cornus product processing workshops, etc., and can effectively solve the problems existing in traditional sterilization methods, improve the quality and safety of cornus products, and meet consumers' demand for healthy food.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0065] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
