DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a high-temperature sterilization device for food production, comprising a steam sterilization box 1, a steam inlet pipe and a steam exhaust pipe being arranged on the top of the steam sterilization box 1, and control valves being connected in series on the steam inlet pipe and the steam exhaust pipe, so as to facilitate the injection of high-temperature steam into the steam sterilization box 1 and the discharge of the steam in the steam sterilization box 1.

[0023] A bracket 2 is provided below the steam sterilizer 1. A belt conveyor 3 passing under the steam sterilizer 1 is provided on the bracket 2. The bracket 2 supports the steam sterilizer 1 and the belt conveyor 3. The outer periphery of the belt conveyor 3 is provided with a vertical and circumferentially evenly distributed guide shaft 4. The guide shaft 4 is axially slidable and one end of which is fixedly connected to a tray 5 located outside the belt conveyor 3. The tray 5 is used to place components for pre-prepared dishes. When the belt conveyor 3 is in operation, the evenly arranged trays 5 above it move synchronously. The bottom of the steam sterilizer 1 is provided with an inlet and outlet 11 connecting to the inner cavity. The evenly distributed trays 5 that move synchronously will pass under the inlet and outlet 11 in turn.

[0024] The belt conveyor 3 is provided with a lifting rod 6 located below the inlet and outlet 11 and used in conjunction with the guide shaft 4. The lifting rod 6 can be an oil cylinder or an air cylinder. Its function is to push the guide shaft 4 thereon upward. The pushed guide shaft 4 will drive the corresponding tray 5 closer to the inlet and outlet 11, so that the pre-prepared dishes on the tray 5 pass through the inlet and outlet 11 and enter the sterilization chamber in the steam sterilizer 1. After sterilization is completed, the tray 5 is controlled to descend, and then the belt conveyor 3 is started to move the next tray 5 to the bottom of the inlet and outlet 11. Such cyclic control can sterilize the pre-prepared dishes on the belt conveyor 3 in sequence, greatly improving the efficiency of the sterilization process.

[0025] Furthermore, a sealing plate 12 is fixedly connected to the bottom of the steam sterilizer 1, and the inlet and outlet 11 are located in the middle of the sealing plate 12. The upper end face of the tray 5 is clamped with a circle of sealing rubber gasket 7 close to the side. The sealing rubber gasket 7 and the lower end face of the sealing plate 12 located around the inlet and outlet 11 cooperate with each other. When the tray 5 rises to contact the sealing plate 12, the sealing rubber gasket 7 is squeezed, which can effectively prevent steam from leaking through the inlet and outlet 11.

[0026] In this embodiment, a mesh cover 51 that can enter and exit the inlet and outlet 11 is fixedly connected to the top of the tray 5. The opening of the mesh cover 51 faces downward, and the top of the mesh cover 51 is used to place pre-prepared dishes. The mesh cover 51 is made of a punched plate. Steam passing through the mesh cover 51 can fully heat and sterilize the pre-prepared groove.

[0027] In this embodiment, the belt conveyor 3 includes a transverse plate 31, chains 32 located at both ends of the transverse plate 31 and a transmission wheel set 33 for supporting the chain 32. The transverse plate 31 is arranged on the outer peripheral wall of the chain 32 and is evenly distributed along the circumference of the chain 32. That is to say, the belt conveyor 3 is a crawler chain conveyor. A guide sleeve 311 is fixedly provided on the middle part of the transverse plate 31 and is sleeved on the outside of the guide shaft 4. When the pallet 5 is in a horizontal state and is not pushed by the lifting rod 6, it is in a state where the bottom is in contact with the transverse plate 31. This arrangement can improve the stability of the pallet 5. In order to further improve the stability of the pallet 5 moving with the chain 32, a pad can be welded on the bottom of the pallet 5 for use with the chain 32, so that the tensioned chain 32 can drive the pallet 5 to move smoothly.

[0028] Furthermore, the transmission wheel assembly 33 includes a transmission shaft 331 and sprockets 332 fixedly mounted on the transmission shaft 331 and close to both ends. The sprockets 332 engage with adjacent chains 32, and the space formed between the two sprockets 332 facilitates the passage of the transmission shaft 331.

[0029] In this embodiment, the external fixed sleeve of the guide shaft 4 is provided with a limit ring 41 near the bottom, and the guide shaft 4 is provided with a reset spring 8 located between the limit ring 41 and the guide sleeve 311. This arrangement ensures that the guide shaft 4 that is not driven by the lifting rod 6 is always in a state of moving to the extreme position in the chain 32, and at the same time facilitates the reset of the tray 5.

[0030] In this embodiment, a crossbeam 21 is welded on the bracket 2 and passes through the inner circle of the chain 32. The lifting rod 6 is fixedly set on the crossbeam 21. The action end of the lifting rod 6 is welded with an insertion shaft 61. The bottom of the guide shaft 4 is provided with a socket 42 adapted to the insertion shaft 61. The insertion shaft 61 and the socket 42 are both conical. The purpose is to ensure that the lifting rod 6 and the guide shaft 4 can stably push up the tray 5 after docking, and the guide shaft 4 will not swing during the process of pushing up the guide shaft 4, which facilitates the stable lifting and lowering of the tray 5.

[0031] Working principle: the packaged pre-prepared dishes are placed on each mesh cover 51 on the upstream side of the steam sterilization box 1, and then the belt conveyor 3 is started. The transmission shaft 331 drives the chain 32 to operate through the sprocket 332, and the tray 5 close to the inlet and outlet 11 moves to the bottom of the inlet and outlet 11. At this time, the transmission shaft 331 is controlled to stop rotating, and then the lifting rod 6 is controlled to push the stroke, the guide shaft 4 rises, the corresponding return spring 8 is compressed, and the corresponding tray 5 and the sealing plate 12 are offset. At this time, the prefabricated groove on the mesh cover 51 enters the steam sterilization box 1, and high-temperature steam is injected into the steam sterilization box 1 for sterilization. After sterilization is completed, the high-temperature steam is discharged, and then the lifting rod 6 is controlled to return, the return spring 8 is extended to assist the guide shaft 4 to descend, and the tray 5 drives the sterilized pre-prepared dishes to leave the steam sterilization box 1, and then the transmission shaft 331 is continued to rotate, so that the adjacent upstream tray 5 moves to the bottom of the inlet and outlet 11, and then the above operation method is cyclically controlled to improve the efficiency of loading and unloading during sterilization.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
