Description

Technical Field

[0001] The invention relates to the technical field of food production and processing, and more specifically, to an autoclave for food processing. Background Art

[0002] Existing sterilization technologies are mainly classified into three categories: thermal sterilization technology, chemical sterilization technology, and non-thermal / low-thermal sterilization technology. Heat treatment (100-120°C) is the most common sterilization method for food, but high-temperature sterilization can easily cause deterioration of sensory quality and loss of nutrients. At the same time, high-temperature sterilization also has the problem of high energy consumption.

[0003] For example, a high-temperature and high-pressure sterilization device disclosed in authorization announcement No. CN220276006U, through the setting of a unloading component, does not require manual unloading by staff, thereby avoiding the problem of too many objects in the sterilization pot and the staff being unable to manually rotate them; through the setting of a hydraulic cylinder, it can drive the support frame to rise and fall to adjust the height, through the setting of a driving motor, it can drive the sterilization pot body to rotate, and through the setting of an easy-to-twist fixing pin, it can fix the clamping block.

[0004] Among the above, there are still some problems in the use of the sterilizer: when the pressure in the pot increases to the required pressure, the fire is reduced, and the steam pressure is maintained at the required pressure for a certain period of time according to the characteristics of the sterilized items. Then the sterilizer is powered off or the fire is turned off, and it is allowed to cool naturally before the exhaust valve is slowly opened to remove the remaining gas. Only then can the lid be opened to take out the items. The cooling time is long and the items are taken out slowly, which affects the work efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] When in use, first inject water into the shell 2, then put the food into the inner pot 1, and then put the inner pot 1 into the shell 2, and make the lower end surface of the inner pot 1 contact the end surface of the placement plate 7, then cover the shell 2 with the sealing cover 4 to seal the shell 2, and then start the electric heating tube through the control panel 3 to heat the water in the shell 2.

[0021] When water is heated, steam is generated. Since the shell 2 is sealed at this time, the air pressure inside the shell 2 will gradually increase. When the air pressure increases, the temperature of the steam will also increase, which can better sterilize the food placed in the inner pot 1.

[0022] After the sterilization work is completed, the drive motor 31 is turned on, and the output end of the drive motor 31 rotates, driving the gear to rotate. Since the gear is engaged with the convex teeth 30 on the outer wall of the buffer ring 24, the gear will drive the buffer ring 24 to rotate. During the rotation of the buffer ring 24, the buffer tube 25 will move to the buffer hole 32, and the steam will enter the buffer groove 27 for buffering to prevent the excessive impact of the steam from rushing out the hose.

[0023] After being buffered, the steam flows out from the docking hole and then enters the water tank 11 through the hose. After entering the water tank 11, the steam first enters the air inlet 14 through the guide pipe 19, and then enters the water storage part 15 through the guide pipe 19. The heat retained in the steam will enter the water, and the water-insoluble part of the steam will be discharged from the water tank 11 through the exhaust hole 1 and the exhaust hole 20.

[0024] When the steam in the inner liner 1 is discharged, the water solenoid valve 13 is opened to supply water to the booster pump 9. The water flows through the booster pump 9 to increase the water pressure, and then presses the piston rod 8. After the piston rod 8 is lifted, the ejector rod 6 is lifted, and then the ejector rod 6 lifts the placement plate 7. The placement plate 7 drives the inner liner 1 to rise, and then the entire inner liner 1 is taken out by machinery, and the next inner liner 1 that needs to be sterilized is placed.

[0025] Then, the water solenoid valve 2 34 is opened to deliver the water used for stamping into the housing 2 for reheating. Since the stamping water has been heated by steam before, energy consumption can be reduced when heating it again.

[0026] Finally, the driving motor 31 is reset, and under the elastic force of the spring 28, the limiting plate 29 is reset to limit the buffer tube 25 again, and then the sealing cover 4 is sealed again, and the water pump is turned on to store water in the water storage tank 11.

[0027] After the work is finished, the water in the shell 2 is discharged through the drain pipe 35 and the nozzle, and the surrounding area of ​​the shell 2 and the ground are washed, thereby increasing the utilization rate of water.

[0028] like Figures 1 to 4 As shown, It includes an inner liner 1 and a shell 2 mounted outside the inner liner 1. A control panel 3 is provided on one side of the shell 2. The control panel 3 is communicated with the booster pump 9, the water pump, the drive motor 31, the water solenoid valve 13 and the water solenoid valve 2 34 so that the control panel 3 controls the orderly operation of each device.

[0029] A sealing cover 4 for sealing the inner container 1 and the shell 2 is connected to the shell 2 , and the sealing cover 4 and the shell 2 are connected by buckles on both sides of the sealing cover 4 .

[0030] The bottom surface of the shell 2 has a drain port, the drain port is connected to a drain pipe 35, the drain pipe 35 is connected to a water valve, and the end of the drain pipe 35 is connected to a nozzle to drain the water in the shell 2.

[0031] The sealing cover 4 includes a cover plate 22, a connecting column 23 and a buffer ring 24 sleeved on the outside of the connecting column 23, the buffer ring 24 has a buffer groove 27, the connecting column 23 is fixed to the upper end surface of the shell 2, and the connecting column 23 has an air intake cavity penetrating the cover plate 22, and the water vapor generated in the inner liner 1 and the shell 2 is discharged through the air intake cavity.

[0032] The outer wall of the connecting column 23 has an air outlet connected to the air inlet cavity. The air entering the air inlet cavity enters the buffer tank 27 through the air outlet. While saving materials, it can also prevent the hose from being pushed out due to excessive pressure at the moment when the steam is released, affecting the heat recovery effect.

[0033] A buffer tube 25 is provided on the air outlet, and the buffer tube 25 is connected to the buffer ring 24. The lower end of the buffer ring 24 is connected to a support rod 26 which is slidably connected to the cover plate 22. The support rod 26 supports the buffer ring 24. Since the sterilizing pot has a relatively large pressure inside during operation, the air pressure will push the sealing cover 4. The support rod 26 can prevent the buffer ring 24 from shaking during operation.

[0034] A connecting groove is provided on the inner wall of the buffer ring 24 corresponding to the buffer tube 25, and a spring 28 is fixedly connected to the side wall of the connecting groove.

[0035] There is a buffer hole 32 connected to the connecting groove at the position corresponding to the spring 28 on the connecting groove. The diameter of the buffer hole 32 is larger than the thickness of the limiting plate 29 plus the diameter of the buffer tube 25. When sterilization is completed, the buffer ring 24 is rotated to align the buffer tube 25 with the buffer hole 32 to discharge the steam in the inner tank 1.

[0036] The outer wall of the buffer ring 24 is provided with a docking hole, to which a hose is connected, and the other end of the hose is connected to the air inlet pipe 18 , through which the steam is transported to the water storage tank 11 .

[0037] A section of convex teeth 30 is provided on the outer wall of the buffer ring 24, and the convex teeth 30 are meshed with a gear. The gear is connected to the output end of a drive motor 31. The drive motor 31 is fixed to the upper end surface of the cover plate 22. The drive motor 31 is electrically connected to the control panel 3. The buffer ring 24 is driven to rotate by the drive motor 31, which avoids the danger caused by manual rotation and ensures the personal safety of the operator.
