Description

Technical Field

[0001] The utility model relates to the technical field of vegetable quick freezing, in particular to a tunnel-type vegetable quick freezing device which is easy to clean and defrost. Background Art

[0002] With the continuous development of the logistics and transportation industry, people can buy more fruits and vegetables from other places. When vegetables are transported over long distances or need to be stored for a long time, they need to be quickly frozen to prolong the freshness of the vegetables and slow down the decay of the vegetables. At present, quick-freezing devices for quick-frozen vegetables often produce lower temperatures during operation. When used for a long time, quick-freezing equipment will produce more frost. In order to clean the frost, a tunnel-type vegetable quick-freezing device that is easy to clean and defrost is proposed.

[0003] Chinese Patent Publication No. CN212590050U discloses a tunnel-type vegetable quick-freezing device that is easy to clean and defrost, comprising a transport box, a connector fixedly mounted on the upper end of the transport box, a refrigeration box fixedly mounted on the upper end of the connector, a limit box fixedly mounted on the upper end of the refrigeration box, a liquid nitrogen input pipe fixedly mounted on the upper end of the limit box, a belt conveyor fixedly mounted inside the transport box, a limiter fixedly mounted on the upper end of the belt of the belt conveyor, and a special-shaped box movably mounted on the upper end of the limiter. The tunnel-type vegetable quick-freezing device that is easy to clean and defrost achieves the effect of limiting and fixing the special-shaped box by setting the limiter, which is conducive to the stable movement of the special-shaped box. By setting the left and right end faces of the special-shaped box to fit the inner side of the connector, and setting the upper end face of the special-shaped box to fit the lower end face of the refrigeration box, the special-shaped box can be defrosted when it moves with the belt conveyor, thereby improving defrosting efficiency and being easy to use.

[0004] When the above prior art is in use, frost may remain on the surface of the conveyor belt, such as the belt in the prior art, and if it is not cleaned, it will affect the use. Utility Model Content

A scraper 9 is fixedly connected between the two fixed plates 8, and the top of the scraper 9 contacts the bottom of the conveyor belt 6. By starting the electric push rod 20, the electric push rod 20 will drive the second connecting pipe 18 to move to the outside of the second connecting frame, thereby driving the threaded hose 21 to stretch, and then driving multiple second nozzles 19 to move to the outside of the second connecting frame until it moves to a suitable distance from the conveyor belt 6. At this time, the conveyor belt 6 is transported under the action of the motor 5, and then the warm water is transported to the threaded hose 21 through the water inlet pipe 15, and then transported to the second connecting pipe 18 through the threaded hose 21, and then transported to the second connecting pipe 18 through the second connecting pipe 18. The second nozzle 19 is finally sprayed with warm water onto the conveyor belt 6 through the second nozzle 19, so that the frost on the surface of the conveyor belt 6 can be melted. If the frost is not melted by warm water in the future, it will be scraped off by the scraper 9 when passing through the two scrapers 9.

[0024] like Figure 1 and Figure 2 As shown, a first fixed frame 11 is fixedly connected to the top of the quick-freezing chamber 1, an input pipe 12 is fixedly connected to the top of the first fixed frame 11, a first connecting pipe 16 is fixedly connected to the bottom of the input pipe 12, and a plurality of first nozzles 17 are fixedly connected to the bottom of the first connecting pipe 16. Liquid nitrogen that can be quickly frozen is transported to the first connecting pipe 16 through the input pipe 12, and then transported to the first nozzle 17 through the first connecting pipe 16, and finally sprayed out through the first nozzle 17.

[0025] like Figure 1 As shown, the quick-freezing bin 1 is fixedly connected to the surface of the fixed base plate 2, a recovery groove 4 is provided on the surface of the fixed base plate 2, a liquid outlet pipe 13 is fixedly connected to one side of the fixed base plate 2, a control panel 10 is fixedly connected to the surface of the quick-freezing bin 1, and a placement frame 7 is placed on the surface of the conveyor belt 6. The control panel 10 is electrically connected to the motor 5 and the electric push rod 20. The recovery groove 4 is used to recycle frost, and the liquid outlet pipe 13 is used to discharge the melted frost in the recovery groove 4. The control panel 10 is used to control the motor 5 and the electric push rod 20, and the placement frame 7 is used to place vegetables that need to be quick-frozen.

[0026] Working principle: When in use, place the vegetables to be frozen into the placement frame 7, and then place the placement frame 7 on the surface of the conveyor belt 6;

[0027] At this time, the electric push rod 20 is activated through the control panel 10, and the electric push rod 20 drives the second connecting pipe 18 to move outside the second connecting frame, thereby driving the threaded hose 21 to stretch, and then driving the multiple second nozzles 19 to move outside the second connecting frame until they are at a suitable distance from the conveyor belt 6;

[0028] Then the conveyor belt 6 is started and rotated, and the conveyor belt 6 drives the placement frame 7 to move into the quick-freezing chamber 1. At this time, the liquid nitrogen that can be quickly frozen is transported to the first connecting pipe 16 through the input pipe 12, and then transported to the first nozzle 17 through the first connecting pipe 16. Finally, it is sprayed onto the surface of the vegetables in the placement frame 7 through the first nozzle 17 for quick freezing. Frost will be generated during quick freezing and remain on the surface of the conveyor belt 6. In order to prevent the frost from affecting the transmission of the conveyor belt 6, the staff will remove the placement frame 7 after the conveyor belt 6 transports the placement frame 7 to a certain distance away from the quick-freezing chamber 1;

[0029] During the conveying process of the conveyor belt 6, warm water is transported to the threaded hose 21 through the water inlet pipe 15, and then transported to the second connecting pipe 18 through the threaded hose 21, and then transported to the second nozzle 19 through the second connecting pipe 18, and finally the warm water is sprayed onto the conveyor belt 6 through the second nozzle 19, so that the frost on the surface of the conveyor belt 6 can be melted. If the frost that has not been melted by the warm water in time will pass through the two scrapers 9, it will be scraped off by the scrapers 9, thereby cleaning the frost on the surface of the conveyor belt 6, and the scraped frost will fall into the recovery tank 4, and the melted frost in the recovery tank 4 will be discharged through the liquid outlet pipe 13.

[0030] Through the above operation, the refrigerator on the surface of the conveyor belt 6 can be cleaned conveniently.
