Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-temperature sterilizer technology, specifically a heat-resistant high-temperature sterilizer for food processing. Background Technology
[0002] In the food processing industry, high-temperature sterilizers are key equipment for ensuring food safety and extending shelf life. They use high temperatures to kill microorganisms in food. When the temperature reaches a certain threshold, the proteins, nucleic acids and other biological macromolecules in the microbial cells will lose their activity due to heat denaturation. This sterilization process minimizes the impact on the nutrition and flavor of the food.
[0003] For example, patent CN213756574U discloses a high-temperature sterilization device for food processing, including a main body, a material tank, an electric push rod, a storage box, and a high-temperature resistant air pump. The material tank is fixedly installed on the top of the main body via the electric push rod. A filter plate is fixedly installed inside the main body, and one end of the filter plate is movably installed with an upper opening and closing door via a hinge. A storage box is provided on one side of the main body, and fixed rods are symmetrically welded to the bottom of the inner side of the main body. Different food raw materials can be sterilized through the filter plate, fixed baffle, and tray, improving sterilization efficiency. The fixed baffle can be raised and lowered via a screw and a lifting plate to facilitate the discharge of food raw materials. The trough, straight pipe, and regulating plate facilitate the addition of food ingredients into the main body, effectively improving the sterilization efficiency of food ingredients. The high-temperature air pump facilitates the circulation of high-temperature air, improving resource utilization. However, the high-temperature sterilizer is in a high-temperature and high-pressure state during use. After processing, the sterilizer chamber and metal parts will remain at a high temperature due to heat conduction. Residual steam or hot water will also remain at a high temperature, resulting in a long cooling time. If there is residual steam inside when the equipment is turned on, the steam will spray out when the door is opened. Direct contact of the high-temperature airflow with the operator's skin can cause steam burns. Furthermore, contact with the food rack when retrieving items can also easily cause burns, limiting the safety of use.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-temperature sterilizers. Utility Model Content
[0005] The purpose of this invention is to provide a scalding-proof high-temperature sterilizer for food processing, in order to solve the problems mentioned in the background art. The high-temperature sterilizer is in a state of high temperature and high pressure inside during use. After processing, the sterilizer chamber and metal parts will remain at a high temperature due to heat conduction. The residual steam or hot water will also remain at a high temperature. The equipment has a long cooling time. If there is residual steam inside when the equipment is turned on, the steam will be sprayed out when the door is opened. The high-temperature airflow will directly contact the operator's skin, which will cause steam burns. Furthermore, it is easy to be burned when the food comes into contact with the food rack when picking up the food. The equipment has limited safety.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-resistant high-temperature sterilizer for food processing, comprising a vertical sterilization shell and a high-temperature inner cylinder fitted inside it, a suitable sealing cover installed at the upper end of the high-temperature inner cylinder, a fixing frame fixedly connected above the sealing cover, and internal threaded locking devices rotatably connected to both ends of the fixing frame, a cylindrical seat fixedly installed on the upper surface of the vertical sterilization shell corresponding to the lower part of the internal threaded locking devices, a cylindrical rod fixedly connected to the upper end of the cylindrical seat along the axial direction, a threaded rod coaxially connected above the cylindrical rod, and the internal threaded locking devices threadedly fitted onto the outside of the threaded rod; a lifting and limiting mechanism is provided on the cylindrical seat to lift and move the sealing cover to assist in the discharge of hot air.
[0007] Preferably, an inner ring is fixedly connected below the sealing cover, and the outer surface of the inner ring is in contact with the inner wall of the high-temperature inner cylinder; multiple vent holes are opened on one side of the inner ring along the circumference.
[0008] Preferably, the lifting and limiting mechanism includes a lifting plate that is slidably sleeved on a cylindrical rod, and a limiting spring is elastically connected between the lifting plate and the cylindrical seat; the lifting plate is elastically supported on the lower end face of the fixed frame.
[0009] Preferably, both the lifting plate and the cylindrical seat have protrusions fixed on the side away from the sealing cover, with the two protrusions distributed vertically and vertically, and each of the two protrusions is rotatably connected to a transmission rod; a transmission block is movably arranged between the two protrusions, and the transmission block is rotatably connected to the upper and lower transmission rods.
[0010] Preferably, a food storage rack is movably fitted into the high-temperature inner cylinder, and the rack is positioned directly below the inner ring; a heat-resistant connecting mechanism for retrieving the rack is provided on the inner ring.
[0011] Preferably, the connecting mechanism includes an arc frame fixedly installed on the upper end face of the space frame, and two sets of arc frames are symmetrically arranged on the space frame about the axis; multiple hooks are fixedly installed on the inner wall of the inner ring.
[0012] Preferably, the hook moves upward and engages with the arc frame through it.
[0013] Compared with the prior art, the beneficial effects of this utility model are: after sterilization and cooling for a period of time, the anti-scalding high-temperature sterilizer for food processing can loosen the installation position of the fixing bracket by rotating the internal thread locking device. Under the lifting action, the sealing cover and inner ring are pushed upward, and the exhaust hole on the inner ring helps to exhaust the residual high-temperature gas inside. Moreover, the exhaust hole avoids the operating range of the staff, thus maintaining the safety of equipment use.
[0014] Furthermore, the cylindrical base is equipped with a lifting and limiting mechanism to assist in the discharge of hot gas by lifting and moving the sealing cover. After the fixed frame is loosened outside the threaded rod, under the elastic lifting action of the lifting plate, the fixed frame and the sealing cover are pushed to move further upward, so that the inner ring moves out of the high-temperature inner cylinder, so that the high-temperature gas remaining in the high-temperature inner cylinder can be discharged outward through the exhaust hole on the inner ring, ensuring that no residual gas inside will harm the human body when the sealing cover is opened manually.
[0015] When opening the sealing cap, control the rotation of the sealing cap so that the hook on the inner ring rotates to the lower position of the arc frame. When lifting the sealing cap upward, the hook moves upward and engages with the arc frame, causing the arc frame and the wire mesh frame to move upward synchronously away from the high-temperature inner cylinder. This allows food to be removed from the high-temperature sterilizer without contact, preventing burns from direct contact. Attached Figure Description

Detailed Implementation
[0024] 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.
[0025] Example 1: Please refer to Figures 1-4 This utility model provides the following technical solution: a heat-resistant high-temperature sterilizer for food processing, comprising a vertical sterilization shell 1 and a high-temperature inner cylinder 2 fitted inside it, a suitable sealing cover 3 installed on the upper end of the high-temperature inner cylinder 2, a fixing frame 4 fixedly connected above the sealing cover 3, and internal threaded locking devices 5 rotatably connected to both ends of the fixing frame 4, a cylindrical seat 6 fixedly installed on the upper surface of the vertical sterilization shell 1 corresponding to the lower part of the internal threaded locking device 5, a cylindrical rod 7 fixedly connected to the upper end of the cylindrical seat 6 along the axial direction, a threaded rod 8 coaxially connected above the cylindrical rod 7, and the internal threaded locking device 5 threadedly fitted on the outside of the threaded rod 8; a lifting and limiting mechanism is provided on the cylindrical seat 6 to lift and move the sealing cover 3 to assist in the discharge of hot air.
[0026] Please see Figure 5 and Figure 6 An inner ring 31 is fixedly connected below the sealing cover 3. The outer surface of the inner ring 31 is in contact with the inner wall of the high-temperature inner cylinder 2. Multiple exhaust holes 32 are opened on one side of the inner ring 31 along the circumference.
[0027] Please see Figures 2-4 The lifting and limiting mechanism includes a lifting plate 9 slidably sleeved on a cylindrical rod 7, with a limit spring 10 elastically connected between the lifting plate 9 and the cylindrical seat 6; the lifting plate 9 is elastically supported on the lower end face of the fixed frame 4. Both the lifting plate 9 and the cylindrical seat 6 have protrusions 11 fixed on the side away from the sealing cover 3, with two protrusions 11 distributed vertically and vertically, and each protrusion 11 is rotatably connected to a transmission rod 12; a transmission block 13 is movably arranged between the two protrusions 11, and the transmission block 13 is rotatably connected to the upper and lower transmission rods 12.
[0028] The wire mesh frame 14 is placed inside the high-temperature inner cylinder 2. Food is placed inside the wire mesh frame 14. The control sealing cover 3 is installed on the upper end of the high-temperature inner cylinder 2. The sterilization temperature and pressure in the high-temperature inner cylinder 2 are controlled by the operation panel on the vertical sterilization shell 1 to achieve sterilization of the food.
[0029] After processing, the high-temperature inner cylinder 2 contains a large amount of high-temperature and high-pressure gas. The exhaust pipe on the vertical sterilization shell 1 can discharge the gas to the outside. Combined with the cooling system or natural cooling, after the temperature in the high-temperature inner cylinder 2 drops, the sealing cover 3 is opened to take out the food. Due to the long cooling time, some hot air may still remain inside when the staff opens the sealing cover 3, which may easily cause burns. It is necessary to open part of the sealing cover 3 in advance to help discharge the internal gas and help the internal and external gas convection to further reduce the internal temperature.
[0030] The internal thread locking device 5 rotates outside the threaded rod 8, causing the fixed frame 4 to move upward. After the internal thread locking device 5 and the threaded rod 8 rotate and separate, the lifting plate 9 supported below the fixed frame 4 moves further upward under the elastic thrust of the lower limiting spring 10. The transmission rod 12 connected between the lifting plate 9 and the cylindrical seat 6 rotates and adjusts, limiting the lifting height of the lifting plate 9, so that the lifting plate 9 can push the fixed frame 4 upward in a short distance. The fixed frame 4 drives the sealing cover 3 to move upward synchronously. The inner ring 31 on the sealing cover 3 moves upward to expose the exhaust hole 32. The residual gas in the high-temperature inner cylinder 2 is discharged outward through the exhaust hole 32. The exhaust hole 32 avoids the operating area of the staff to prevent burns from exhaust. At the same time, it accelerates the convection of internal and external gases and helps to reduce the temperature in the high-temperature inner cylinder 2 so that the food inside can be removed more quickly.
[0031] Example 2: Please refer to Figures 5-7 Based on Embodiment 1, a wire mesh frame 14 and a connecting mechanism are also disclosed, with the following specific structure: A wire mesh frame 14 for placing food is movably fitted into the high-temperature inner cylinder 2, and the wire mesh frame 14 is positioned directly below the inner ring 31; a connecting mechanism for preventing scalding and retrieving the wire mesh frame 14 is provided on the inner ring 31. The connecting mechanism includes an arc frame 15 fixedly installed on the upper surface of the wire mesh frame 14, with two sets of arc frames 15 symmetrically arranged about the axis on the wire mesh frame 14; multiple hooks 16 are fixedly installed on the inner wall of the inner ring 31. The hooks 16 move upward and engage with the arc frames 15.
[0032] After the gas in the high-temperature inner cylinder 2 has been released for a period of time, the sealing cover 3 is rotated by the fixing bracket 4, so that the hook 16 on the inner ring 31 rotates to correspond to the position below the arc frame 15 on the wire mesh frame 14. Then, the fixing bracket 4 and the sealing cover 3 are lifted upwards. The sealing cover 3 drives the inner ring 31 and the hook 16 to move upwards synchronously. During the upward movement, the hook 16 penetrates and engages inside the arc frame 15. During the continued upward lifting of the sealing cover 3, the hook 16 can move the arc frame 15 and the wire mesh frame 14 upwards synchronously, so that the wire mesh frame 14 is separated from the high-temperature inner cylinder 2. This achieves a non-contact method to remove food from the high-temperature inner cylinder 2, avoiding contact burns during the process of removing the food and improving the safety of equipment use.
