Description

Technical Field

[0001] This utility model relates to the field of high-pressure sterilization technology, specifically a high-pressure sterilization and cooling device. Background Technology

[0002] High-pressure steam sterilizers are devices that use saturated pressure steam to quickly and reliably disinfect and sterilize items. They are classified according to style and size into portable high-pressure steam sterilizers, vertical high-pressure steam sterilizers, etc. They utilize the strong penetrating power of pure steam, which denatures and coagulates proteins and protoplasmic colloids under moist heat conditions, and easily destroys enzyme systems. Steam enters cells and condenses into water, releasing potential heat to increase the temperature and further enhance the sterilization power. Steam sterilization is widely used in pharmaceutical and food processing.

[0003] When using a conventional high-pressure steam sterilizer, if the amount of raw materials is large, the steam cannot make sufficient contact with the raw materials in the first place, resulting in an excessively long sterilization time. In addition, the natural cooling and depressurization time after sterilization is also long, which in turn prolongs the sterilization time and leads to a decrease in production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-pressure sterilization and cooling device, which has the advantage of improving sterilization efficiency and avoids the problem of low sterilization efficiency.

[0005] To improve sterilization efficiency, this utility model provides the following technical solution:

[0006] A high-pressure sterilization and cooling device includes a barrel body, a cover plate snapped onto the top of the barrel body, a sterilization assembly installed on the side wall of the barrel body for high-temperature and high-pressure sterilization, and a cooling assembly installed at the bottom of the cover plate for cooling the inner cavity of the barrel body. The device also includes:

[0007] The sterilization assembly includes a placement plate, which is fixedly installed on the inner wall of the barrel. The surface of the placement plate has air holes. A steam generator is fixedly connected to the side wall of the barrel. An air outlet pipe is fixedly connected to the output end of the steam generator. The air outlet pipe is located below the placement plate in the inner cavity of the barrel and is set to be open.

[0008] According to some embodiments, a servo motor is fixedly connected to the top of the cover plate, a threaded column is fixedly connected to the output end of the servo motor, a pressure plate is threadedly connected to the side wall of the threaded column, and a rotating plate is fixedly connected to the bottom of the side wall of the threaded column.

[0009] According to some embodiments, the cooling assembly includes a cooling box, which is fixedly installed on the side wall of the barrel. A connecting pipe is fixedly connected to the top of the cooling box and extends to below the pressure plate. A negative pressure pump is fixedly connected to the top of the cover plate, and the connecting pipe is connected to the negative pressure pump. The cooling box is connected to a steam generator.

[0010] According to some embodiments, the top of the barrel is provided with a groove, the bottom of the cover plate is fixedly connected with a sealing strip, and the sealing strip can extend into the inner cavity of the groove. The side walls of the barrel and the cover plate are both fixedly connected with connecting plates, the top of the connecting plates is threaded with a fixing bolt, the bottom of the cover plate is fixedly connected with a limiting post, and the limiting post penetrates the pressure plate.

[0011] Beneficial effects

[0012] This utility model provides a high-pressure sterilization and cooling device, which has the following beneficial effects:

[0013] (1) The high-pressure sterilization and cooling device places the raw material on the surface of the placement plate, seals the barrel with the cover plate, drives the steam generator to fill the inner cavity of the barrel with steam through the steam outlet pipe. Since the surface of the placement plate is provided with air holes, the steam can then flow upward through the air holes. During this process, the raw material will move. At the same time, the threaded column drives the rotating plate to rotate, thereby stirring the raw material, so that the raw material can be evenly contacted with the steam, so that the raw material is subjected to high-pressure and high-temperature sterilization, thereby reducing the high-temperature sterilization time.

[0014] (2) When the raw materials in the inner cavity of the barrel are sterilized, the high-pressure sterilization and cooling device drives the negative pressure pump to draw the steam under the pressure plate into the inner cavity of the cooling box through the connecting pipe, thereby achieving the effect of cooling and depressurization. At the same time, the steam can be quickly condensed into water when it enters the inner cavity of the cooling box, and can be re-entered into the inner cavity of the steam generator for reuse.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 A high-pressure sterilization and cooling device includes a barrel body 1, a cover plate 101 snapped onto the top of the barrel body 1, a sterilization component 2 installed on the side wall of the barrel body 1, the sterilization component 2 being used for high-temperature and high-pressure sterilization, and a cooling component 3 installed at the bottom of the cover plate 101, the cooling component 3 being used to cool the inner cavity of the barrel body 1, and further includes:

[0022] The sterilization component 2 includes a placement plate 201, which is fixedly installed on the inner wall of the barrel 1. The surface of the placement plate 201 is provided with air holes. A steam generator 202 is fixedly connected to the side wall of the barrel 1. An air outlet pipe 203 is fixedly connected to the output end of the steam generator 202. The air outlet pipe 203 is located below the placement plate 201 in the inner cavity of the barrel 1 and is set to be open.

[0023] A servo motor 204 is fixedly connected to the top of the cover plate 101, and a threaded post 205 is fixedly connected to the output end of the servo motor 204.

[0024] A pressure plate 206 is threadedly connected to the side wall of the threaded column 205, and a rotating plate 207 is fixedly connected to the bottom of the side wall of the threaded column 205.

[0025] It should be noted that: the raw materials are placed on the surface of the placement plate 201 inside the barrel 1, and the barrel 1 is sealed with the cover plate 101. Then, the steam generator 202 can be driven to fill the inner cavity of the barrel 1 with steam through the air outlet pipe 203. Since the surface of the placement plate 201 is provided with air holes, the steam can flow upward through the air holes. In this process, it will cause the raw materials to move. At the same time, the servo motor 204 drives the threaded column 205 to rotate. The threaded column 205 drives the rotating plate 207 to rotate, thereby stirring the raw materials so that the raw materials can be evenly impacted by the steam. Since the threaded column 205 and the pressure plate 206 are threadedly connected, the pressure plate 206 can be driven to move downward, thereby reducing the space inside the barrel 1. Combined with the steam, it can play a role in pressurization, thereby subjecting the raw materials to high pressure and high temperature sterilization.

[0026] Reference Figures 1-4 The cooling component 3 includes a cooling box 301, which is fixedly installed on the side wall of the barrel 1. A connecting pipe 302 is fixedly connected to the top of the cooling box 301, and the connecting pipe 302 extends to the bottom of the pressure plate 206.

[0027] A negative pressure pump 303 is fixedly connected to the top of the cover plate 101, and the connecting pipe 302 is connected to the negative pressure pump 303. The cooling box 301 is connected to the steam generator 202.

[0028] It should be noted that after the raw materials in the inner cavity of the barrel 1 have been sterilized, the negative pressure pump 303 can be driven. The negative pressure pump 303 can draw the steam below the pressure plate 206 into the inner cavity of the cooling box 301 through the connecting pipe 302, thereby achieving the effect of cooling and depressurization. At the same time, the steam entering the inner cavity of the cooling box 301 can be quickly condensed into water and can re-enter the inner cavity of the steam generator 202 for reuse.

[0029] Reference Figures 1-4 The top of the barrel 1 has a groove, and the bottom of the cover plate 101 is fixedly connected to a sealing strip 4, which can extend into the inner cavity of the groove.

[0030] Both the barrel body 1 and the cover plate 101 are fixedly connected to the side walls of the connecting plate 401, and the top of the connecting plate 401 is threadedly connected to the fixing bolt 402.

[0031] The bottom of the cover plate 101 is fixedly connected to a limiting post 403, and the limiting post 403 penetrates the pressure plate 206. The connecting pipe 302 is made of elastic material.

[0032] It should be noted that the barrel body 1 and the cover plate 101 are fixed by the fixing bolt 402 at the top of the connecting plate 401, and the sealing strip 4 at the bottom of the cover plate 101 can extend to the inner cavity of the groove opened at the top of the barrel body 1, which can enhance the sealing effect of the barrel body 1. The limiting post 403 can prevent the pressure plate 206 from rotating with the threaded post 205. The connecting pipe 302 is made of elastic material, which makes it easy for the connecting pipe 302 to move with the cover plate 101 and the pressure plate 206.

[0033] Operating method: Place the raw material on the surface of the placement plate 201 inside the barrel 1, and seal the barrel 1 with the cover plate 101. Then, drive the steam generator 202 to fill the inner cavity of the barrel 1 with steam through the steam outlet pipe 203. Since the surface of the placement plate 201 is provided with air holes, the steam can flow upward through the air holes. In this process, it will cause the raw material to move. At the same time, drive the servo motor 204 to drive the threaded column 205 to rotate. The threaded column 205 drives the rotating plate 207 to rotate, thereby stirring the raw material so that the raw material can be evenly impacted by the steam. Since the threaded column 205 and the pressure plate 206 are threadedly connected, the pressure plate 206 can be driven to move downward, thereby reducing the space inside the barrel 1. Combined with the steam, it can play a pressurizing role, thereby subjecting the raw material to high pressure and high temperature sterilization.

[0034] After the raw materials in the inner cavity of the barrel 1 are sterilized, the negative pressure pump 303 can be driven. The negative pressure pump 303 can draw the steam below the pressure plate 206 into the inner cavity of the cooling box 301 through the connecting pipe 302, thereby achieving the effect of cooling and depressurization. At the same time, the steam entering the inner cavity of the cooling box 301 can be quickly condensed into water and can re-enter the inner cavity of the steam generator 202 for reuse.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
