Technical Field
[0001] This utility model relates to the field of pressure vessel technology, specifically a positive pressure vessel for rapid rehydration and processing of convenient foods. Background Technology
[0002] Quick-refreshing convenience foods are an ideal choice for today's fast-paced lifestyle. These foods utilize advanced freeze-drying or vacuum packaging technology to lock in the freshness and nutrients of the ingredients. Simply heat or rehydrate them to quickly restore delicious meals. Whether on a busy workday or while traveling, they provide a convenient and healthy dining solution. A wide variety of options are available, including main dishes, snacks, and soups, catering to different tastes and allowing people to enjoy delicious food while maintaining nutrition and health.
[0003] In the processing and production process, in order to kill microorganisms, positive pressure vessels are required, and high-temperature and high-pressure steam is used to sterilize the food. The food placement basket is placed on a movable support, and then pushed into the interior by a transfer device, where it is sterilized by high-temperature and high-pressure steam.
[0004] Traditional pressure vessels have steam vents evenly distributed throughout the interior. However, during sterilization processes, there are instances where the food baskets on the support are not fully filled, while the density of the emitted high-temperature, high-pressure steam remains constant. This means that sterilizing small quantities of food still requires a considerable amount of time. Therefore, we propose a positive pressure vessel for the rapid repackaging and processing of convenient foods. Utility Model Content
[0005] The purpose of this invention is to provide a positive pressure container for rapid refreshing and processing of convenient foods. By using upper hooks to support and fix multiple steam nozzles inside the insulated container, and by fixing side hooks on the side support rods on both sides of the mesh plate used to place the baskets, the steam nozzles can be evenly distributed on both sides of the baskets according to the number of baskets used. When fewer baskets are used, a higher density of steam nozzles will be placed, which can achieve the purpose of rapid sterilization of small amounts of food and solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a positive pressure container for rapid refreshing and processing of convenient food, comprising an insulated tank and a movable plate. Rollers are installed at the four corners of the bottom of the movable plate, which is supported by the rollers and placed inside the lower part of the insulated tank. Parallel side support rods are vertically fixed on both sides of the movable plate, evenly distributed in the longitudinal direction. A mesh plate is horizontally fixed between the side support rods on both sides. Multiple upper hooks are evenly fixed on the upper part of the insulated tank, evenly distributed in the longitudinal direction. These upper hooks provide longitudinal support for multiple steam nozzles placed inside the insulated tank. The surface of each steam nozzle is evenly provided with nozzles communicating with its interior. Side hooks are fixed on the surface of the side support rods on both sides of each mesh plate, and at least three sets of side hooks are provided on both sides of each mesh plate in the vertical direction.
[0007] By adopting the above technical solution, multiple movable steam nozzles are installed inside the heat-insulating tank. Depending on the number of baskets used for support, steam nozzles are installed on both sides of each basket when there are many baskets, and the density of steam nozzles on both sides of the baskets is increased when there are few baskets. This achieves the goal of reducing the consumption time and increasing the sterilization speed when there is a small amount of food to be sterilized.
[0008] Optionally, a pressure relief valve is connected to the top center of the heat insulation tank, and the pressure relief valve is in communication with the interior of the heat insulation tank.
[0009] By adopting the above technical solution, when the pressure inside the heat insulation tank is too high, the pressure can be automatically released through the pressure relief valve.
[0010] Optionally, the bottom of the heat insulation tank at the bottom of the roller is provided with a guide groove in the longitudinal direction, and the roller support is placed in the guide groove.
[0011] By adopting the above technical solution, the roller is guided to roll by the guide groove.
[0012] Optionally, the side of the heat-insulating tank is connected to a steam pipe that extends into its interior, and the steam nozzle is connected to the steam pipe via a heat-resistant hose.
[0013] By adopting the above technical solution, high-temperature steam is introduced into the steam nozzle through the steam pipe.
[0014] Optionally, a sealing door is installed at the front end of the heat insulation tank via a hinge, and a sealing rubber ring is fixed to the outer ring of the inner surface of the sealing door.
[0015] By adopting the above technical solution, the purpose of sealing the heat insulation tank is achieved through a sealing door.
[0016] Optionally, a latch is installed on the side of the sealed door, and a handle is also fixed to the surface of the sealed door.
[0017] By adopting the above technical solution, the sealed door is locked by a latch after it is closed, and the sealed door can be pulled by a handle.
[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0019] 1. The technical solution of this application uses upper hooks to support and fix multiple steam nozzles inside the heat-insulating tank, and side hooks are fixed on the side support rods on both sides of the mesh plate used to place the baskets. The steam nozzles can be evenly distributed on both sides of the baskets according to the number of baskets used. When the number of baskets used is small, a higher density of steam nozzles will be placed, which can achieve the purpose of rapid sterilization of a small amount of food.
[0020] 2. The technical solution of this application has a pressure relief valve connected to the top of the heat insulation tank and communicating with its interior. When the pressure inside the heat insulation tank is too high, the pressure relief valve can automatically release the pressure to avoid danger. Attached Figure Description

[0026] Please see Figure 1-3 This utility model provides a technical solution: a positive pressure container for rapid refreshing and processing of convenient food, including an insulated tank 1 and a movable plate 3. Rollers 34 are installed at the four corners of the bottom of the movable plate 3. The bottom of the insulated tank 1 at the bottom of the rollers 34 is provided with a guide groove 11 in the longitudinal direction. The guide grooves 11 on both sides are parallel to each other, so that the rollers 34 are supported in the guide grooves 11. Thus, the movable plate 3 is supported by the rollers 34 and placed inside the lower part of the insulated tank 1. It can be pushed in and pushed out by the rolling of the rollers 34.
[0027] Parallel side support rods 31 are vertically fixed above both sides of the movable plate 3. The side support rods 31 are evenly distributed in the longitudinal direction. A mesh plate 32 is horizontally fixed between the side support rods 31 on both sides, so that there are four mesh plates 32, which can support and place four baskets containing convenience food, and thus push them into the interior of the heat-insulating tank 1.
[0028] Multiple upper hooks 12 are evenly fixed inside the upper part of the heat insulation tank 1. Multiple upper hooks 12 are evenly distributed in the longitudinal direction. Multiple steam nozzles 4 are longitudinally supported inside the upper part of the heat insulation tank 1 through the upper hooks 12. Spray holes 41 communicating with the inside are evenly arranged on the surface of the steam nozzles 4. A steam pipe 13 that penetrates into the inside is connected to the side of the heat insulation tank 1. The steam nozzles 4 are connected to the steam pipe 13 through heat-resistant hoses. The steam nozzles 4 can be removed and slid down to be supported on the upper hooks 12 for storage.
[0029] Each mesh plate 32 has side hooks 33 fixed on the surface of the side support rods 31 on both sides. Each mesh plate 32 has at least three sets of side hooks 33 in the vertical direction on both sides, so that steam nozzles 4 can be placed vertically on both sides of each mesh plate 32. When needed, three steam nozzles 4 can be placed vertically on both sides of each mesh plate 32. Therefore, when baskets are placed on the surface of each mesh plate 32, one steam nozzle 4 can be placed vertically on the surface of each mesh plate 32 on both sides of each basket. When fewer baskets are placed on the surface of each mesh plate 32, two or three steam nozzles 4 can be placed vertically on the surface of each mesh plate 32 on both sides of the basket. This can achieve the purpose of sterilizing a large amount of food at the same time, or the purpose of rapid sterilization of a small amount of food. Both have high sterilization efficiency.
[0030] A sealing door 2 is installed at the front end of the heat insulation tank 1 via a hinge. A sealing rubber ring is fixed to the outer ring of the inner surface of the sealing door 2. A handle is also fixed to the surface of the sealing door 2, which can be pulled to open and close. A latch is installed on the side of the sealing door 2. The sealing door 2 is locked by the latch after it is closed. A pressure relief valve 14 is connected to the middle of the top of the heat insulation tank 1. The pressure relief valve 14 is connected to the inside of the heat insulation tank 1. When the pressure inside the heat insulation tank 1 is too high due to the introduction of high temperature steam, the pressure can be automatically relieved through the pressure relief valve 14.
[0031] In use, the steam pipe 13 is connected to the high-temperature steam generator. The lock on the sealing door 2 of the heat insulation tank 1 is released. Then, the sealing door 2 is opened and the moving device is pushed to the front side of the heat insulation tank 1. The moving plate 3 and the device above it are pushed out of the heat insulation tank 1 by the rolling action of the roller 34 and placed above the moving device, so that they can be removed. The convenience food to be sterilized is placed in the basket and then placed on the surface of different mesh plates 32 for support. Then, the moving plate 3 is pushed into the heat insulation tank 1, so that the roller 34 is supported in the guide groove 11. If there are baskets supported on three mesh plates 32 or all mesh plates 32, all steam nozzles 4 are removed from the top of the hook 12. A steam nozzle 4 is longitudinally arranged on both sides of each mesh plate 32. The steam nozzles 4 are supported on the side hooks 33 on both sides, so that steam nozzles 4 are longitudinally arranged on both sides of each basket. At the same time, the nozzles 41 on the surface of the steam nozzles 4 are adjusted to face the baskets on their sides. Then, the sealing door is closed. 2. Seal the heat-insulating tank 1, start the high-temperature steam generator, and introduce high-temperature steam into the steam nozzle 4 through the steam pipe 13. Then, spray it out from the nozzle 41 into the heat-insulating tank 1 to sterilize the food in the baskets nearby. When only two mesh plates 32 support the baskets, the side hooks 33 are used to longitudinally support two steam nozzles 4 on both sides of each basket (i.e., a total of four steam nozzles 4 are longitudinally arranged on the left and right sides of each basket). Similarly, the nozzles 41 of the steam nozzles 4 are oriented towards the baskets nearby. By increasing the density of the steam nozzles 4 on the outer ring of a single basket, the speed of high-temperature sterilization can be increased. When only one mesh plate 32 supports the basket, the side hooks 33 are used to longitudinally support three steam nozzles 4 on both sides of each basket (i.e., a total of six steam nozzles 4 are longitudinally arranged on the left and right sides of the basket). Similarly, the nozzles 41 of the steam nozzles 4 are oriented towards the baskets nearby, which can further improve the sterilization speed of a small amount of food. The introduction of high-temperature steam will increase the internal pressure of the insulation tank 1. When the pressure is too high, the steam can be discharged from the pressure relief valve 14 to prevent the internal pressure of the insulation tank 1 from becoming too high. After sterilization, stop the introduction of high-temperature steam, open the sealing door 2, and use heat-resistant gloves to reset the steam nozzle 4 before pushing out the moving plate 3 and the structure above it again.
