Description

Technical Field

[0001] This utility model belongs to the field of pre-packaged food sterilization technology, specifically referring to a pre-packaged food sterilization device. Background Technology

[0002] Food sterilization targets food raw materials and processed products, stabilizing food quality and effectively extending shelf life by killing and eliminating microorganisms—the main factors causing food spoilage. This also reduces the number of harmful bacteria in food, preventing human infection from live bacteria or poisoning from pre-existing bacterial toxins. During food production and processing, sterilization equipment is used to disinfect food in order to improve its edibility.

[0003] In existing technologies, traditional batch sterilization equipment suffers from energy waste. Before each batch sterilization, the pot and cold air need to be reheated to the sterilization temperature, and the high-temperature steam needs to be directly discharged during cooling, making it impossible to recover heat. Furthermore, steam sterilization adopts a single-stage operation method, which affects the efficiency of continuous sterilization processing, increases the processing cycle, and affects the efficiency of use. Utility Model Content

[0004] The technical problem this invention aims to solve is that pre-packaged food sterilization equipment suffers from heat waste, lacks multi-stage processing capabilities, has a limited processing cycle, and affects the efficiency of continuous processing.

[0009] Furthermore, a feeding platform is fixedly connected to the inlet side of the processing chassis, and a discharge platform is fixedly connected to the outlet side of the processing chassis. A mounting plate is fixedly connected to the feeding platform, and a cylinder passes through the mounting plate. A conveying push plate is fixedly connected to the output end of the cylinder.

[0010] Furthermore, a U-shaped frame is mounted on the upper part of the processing unit, located above the precooling chamber. A heating water tank is mounted on the upper part of the U-shaped frame. An electric heating tube is provided on the outer wall of the heating water tank. A control valve is connected to the lower part of the heating water tank. The control valve is connected to a spray head installed through the upper part of the precooling chamber via a pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] Example 1:

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a pre-packaged food sterilization equipment, including a processing box 1, a conveying chamber 11 inside the processing box 1, a transfer bracket 12 slidably disposed inside the conveying chamber 11, guide grooves 13 on both sides of the transfer bracket 12, a ventilation mesh frame 14 at the bottom of the transfer bracket 12, and a multi-stage processing unit, the multi-stage processing unit including a preheating chamber 2, a sterilization chamber 21 and a precooling chamber 22 disposed on the processing box 1 along the material conveying direction, a high-pressure steam generator 23 disposed on the upper part of the sterilization chamber 21, and a steam conveying pipe 24 connected to the sterilization chamber 21 on the high-pressure steam generator 23.

[0024] The material is placed on the ventilated mesh frame 14 inside the transfer tray 12. Multiple sets of transfer trays 12 are continuously pushed into the conveying chamber 11 for processing. The front transfer tray 12 is pushed one by one to slide, which can achieve continuous conveying. The material is processed in sequence through the preheating chamber 2, the sterilization chamber 21 and the precooling chamber 22 to avoid the food quality being affected by sudden temperature changes. High-temperature steam is generated by the high-pressure steam generator 23 and transported to the sterilization chamber 21 through the steam conveying pipe 24 for sterilization.

[0025] The preheating chamber 2 is connected to the preheating air intake housing 3 at the top. The preheating air intake housing 3 is equipped with an air pump 31 at the top. The air pump 31 is connected to a waste heat circulation pipe 32. The processing box 1 is equipped with a waste heat recovery housing 33 at the bottom, which is connected to the bottom of the processing box 1. The end of the waste heat circulation pipe 32 is connected to the waste heat recovery housing 33.

[0026] During the steam sterilization process, steam passes through the ventilation mesh frame 14, and waste heat and condensate are collected in the waste heat recovery housing 33. In the preheating chamber 2, the exhaust pump 31 works to extract hot air with waste heat from the waste heat circulation pipe 32 and transport it from the preheating air intake housing 3 to achieve preheating air intake treatment, raising the material to a temperature close to sterilization and reducing heat loss.

[0027] The inlet and outlet of the processing chassis 1 are provided with silicone sealing rings 4 to enhance the sealing performance. A feeding platform 5 is fixedly connected to the inlet side of the processing chassis 1, and a discharge platform 51 is fixedly connected to the outlet side of the processing chassis 1. A mounting plate 52 is fixedly connected to the feeding platform 5, and a cylinder 53 passes through the mounting plate 52. A conveying push plate 54 is fixedly connected to the output end of the cylinder 53. When the transfer bracket 12 is placed on the feeding platform 5, the output end extends when the cylinder 53 is working, and the cylinder 53 is used to push and convey the material. The discharge platform 51 serves to support the material discharge.

[0028] Example 2:

[0029] like Figure 1 , 2 As shown, a U-shaped frame 6 is mounted on the upper part of the processing unit 1, located above the pre-cooling chamber 22. A heating water tank 61 is mounted on the upper part of the U-shaped frame 6. An electric heating tube is provided on the outer wall of the heating water tank 61. A control valve 62 is connected to the lower part of the heating water tank 61. The control valve 62 is connected to a spray head 63 that penetrates the upper part of the pre-cooling chamber 22 through a pipe. A connecting frame 7 is fixed to the rear of the U-shaped frame 6. A hot air blower housing 71 is fixed to the connecting frame 7. An electric heating wire is provided inside the hot air blower housing 71. A drying fan 72 passes through the hot air blower housing 71.

[0030] It should be noted that the equipment can be adjusted via PLC controller 73. After water is stored in the heating water tank 61, the temperature is raised to 80-90℃ through the electric heating tube. In specific use, when the transfer tray 12 moves into the pre-cooling chamber 22 and the control valve 62 is opened, hot water is sprayed onto the material through the spray head 63 for pre-cooling, which can cool it to 60-70℃. Subsequently, after the material is discharged from the transfer tray 12, it moves to the bottom of the hot air blower housing 71, where the electric heating wire heats the material and the drying fan 72 works to blow clean hot air at 40-50℃ to dry the surface moisture of the packaging, preventing mold growth during subsequent storage and achieving stepped cooling. This avoids direct discharge, which can easily cause the packaging to break due to thermal expansion and contraction.

[0031] The above is the entire usage process of a pre-packaged food sterilization equipment.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
