Description

Technical Field

[0001] This invention relates to the field of food production and processing technology, and more specifically, to a sterilizer for food processing. Background Technology

[0002] Existing sterilization technologies are mainly classified into three categories: heat sterilization technology, chemical sterilization technology, and non-heat / low-heat 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 number CN220276006U, through the setting of the unloading component, eliminates the need for manual unloading by the staff, thereby avoiding the problem that the staff cannot manually rotate the sterilizer when there are too many objects in it; through the setting of the hydraulic cylinder, the support frame can be driven to lift and adjust the height; through the setting of the drive motor, the sterilizer body can be driven to rotate; and through the setting of the easy-tight fixing pin, the clamping block can be fixed.

[0004] The above-mentioned issues still exist in the use of sterilizers: when the pressure inside the sterilizer increases to the required pressure, the heat is reduced, and the steam pressure is maintained at the required pressure for a certain period of time according to the characteristics of the items being sterilized. Then, the power or heat of the sterilizer is turned off, and it is allowed to cool naturally before the exhaust valve is slowly opened to remove the residual gas. Only then can the lid be opened and the items removed. The cooling time is long, the removal of items is slow, which affects work efficiency, and the heat loss during cooling results in energy waste.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0028] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] In use, water is first injected into the shell 2, then the food is placed in the inner container 1, and then the inner container 1 is placed in the shell 2, and the lower end surface of the inner container 1 is in contact with the end surface of the placement disc 7, and then the sealing cover 4 is placed on the shell 2 to seal the shell 2, and then the electric heating tube is started through the control panel 3 to heat the water in the shell 2.

[0030] When the water is heated, steam will be generated, and since the shell 2 is sealed at this time, the air pressure in the shell 2 will gradually increase, and at the same time, the temperature of the steam will also increase, which can better sterilize the food placed in the inner container 1.

[0031] After the sterilization work is completed, the driving motor 31 is turned on, the output end of the driving motor 31 rotates to drive the gear to rotate, and since the gear is engaged with the teeth 30 on the outer wall of the buffer ring 24, the gear will drive the buffer ring 24 to rotate, and in the process of rotating, the buffer pipe 25 will move to the buffer hole 32, and the steam will enter the buffer groove 27 to be buffered, avoiding the excessive impact force of the steam from pushing the hose out.

[0032] After the steam is buffered, it flows out from the butt joint hole and enters the water storage tank 11 through the hose, and after the steam enters the water storage tank 11, it first enters the air inlet part 14 through the flow guide pipe 19, and then enters the storage part 15 through the flow guide pipe 19, and the heat remaining in the steam will enter the water, and the part of the steam that is not soluble in water will be discharged from the water storage tank 11 through the exhaust holes one and two 20.

[0033] After the steam in the inner tank 1 is discharged, the water is supplied to the booster pump 9 by opening the solenoid valve 13. The water flow increases the water pressure through the booster pump 9 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 tank 1 to rise. Then, the entire inner tank 1 is removed mechanically and the next inner tank 1 that needs to be sterilized is placed in it.

[0034] Then, the water solenoid valve 2 34 is opened to deliver the water used for stamping into the housing 2 for reheating. Since the water used for stamping has already been heated by steam, reheating reduces energy consumption.

[0035] Finally, the drive motor 31 is reset, and under the elastic force of the spring 28, the limit plate 29 is reset, the buffer tube 25 is limited again, the sealing cover 4 is sealed again, the water pump is turned on, and the water storage tank 11 is filled with water.

[0036] After the work is completed, the water inside the housing 2 is drained through the drain pipe 35 and the nozzle, and the area around the housing 2 and the ground are rinsed, increasing the utilization rate of water.

[0037] like Figs. 1 to 4 As shown,

[0038] It includes an inner tank 1 and a shell 2 fitted outside the inner tank 1. A control panel 3 is provided on one side of the shell 2. The control panel 3 is communicatively connected to a booster pump 9, a water pump, a drive motor 31, a water solenoid valve 13 and a water solenoid valve 2 34, so that the control panel 3 can control the orderly operation of each device.

[0039] The shell 2 is connected to a sealing cover 4 for sealing the inner liner 1 and the shell 2. The sealing cover 4 is connected to the shell 2 by the buckles on both sides of the sealing cover 4.

[0040] The bottom surface of the housing 2 has a drain outlet, which is connected to a drain pipe 35. A water valve is connected to the drain pipe 35, and a nozzle is connected to the end of the drain pipe 35 to drain the water inside the housing 2.

[0041] The sealing cover 4 includes a cover plate 22, a connecting post 23, and a buffer ring 24 sleeved on the connecting post 23. The buffer ring 24 has a buffer groove 27. The connecting post 23 is fixed to the upper end face of the housing 2, and the connecting post 23 has an air inlet chamber that penetrates the cover plate 22. Water vapor generated in the inner liner 1 and the housing 2 is discharged through the air inlet chamber.

[0042] The outer peripheral wall of the connecting column 23 has an air outlet that communicates with the air inlet chamber. The steam entering the air inlet chamber enters the buffer tank 27 through the air outlet, which saves materials and also prevents the hose from being pushed out due to excessive pressure when the steam is released, thus affecting the heat recovery effect.

[0043] The buffer pipe 25 is arranged on the air outlet hole, and the buffer pipe 25 is connected with the buffer ring 24. The lower end of the buffer ring 24 is connected with the supporting rod 26 which is slidingly connected with the cover plate 22. The supporting rod 26 supports the buffer ring 24. Since the sterilization pot has a relatively large pressure inside during the working process, the air pressure pushes the sealing cover 4. The supporting rod 26 can avoid the shaking of the buffer ring 24 during the working process.

[0044] The connecting groove is formed in the inner wall of the buffer ring 24 corresponding to the buffer pipe 25. The spring 28 is fixedly connected to the side wall of the connecting groove. The other end of the spring 28 is fixedly connected with the limiting plate 29 which is used for limiting the buffer pipe 25. The cross section of the limiting plate 29 is arc-shaped. The buffer pipe 25 is fixed in the connecting groove through the limiting plate 29, so as to avoid that the steam in the inner container 1 is discharged through the buffer pipe 25.

[0045] The buffer hole 32 which is in communication with the connecting groove is arranged at the position of the spring 28 on the connecting groove. The diameter of the buffer hole 32 is greater than the thickness of the limiting plate 29 plus the diameter of the buffer pipe 25. After the sterilization is completed, the buffer ring 24 is rotated, so that the buffer pipe 25 is aligned with the buffer hole 32. The steam in the inner container 1 is discharged.

[0046] The butt joint hole is formed in the outer wall of the buffer ring 24. The hose is connected to the butt joint hole. The other end of the hose is connected with the air inlet pipe 18. The steam is transported into the water storage tank 11 through the hose.

[0047] The convex tooth 30 is formed in the outer wall of the buffer ring 24. The convex tooth 30 is engaged with the gear. The gear is connected with the output end of the driving motor 31. The driving motor 31 is fixed to the upper end face of the cover plate 22. The driving motor 31 is electrically connected with the control panel 3. The buffer ring 24 is rotated through the driving motor 31. The danger caused by manual rotation is avoided. The personal safety of the operator is ensured.
