Description

Technical Field

[0001] This utility model belongs to the technical field of dehydrated vegetable equipment, specifically a cooling device for dehydrated onion production. Background Technology

[0002] In the dehydrated vegetable industry, the general process is drying. After drying, the dehydrated vegetables are at a high temperature and need to be cooled before packaging. The usual process is natural cooling, which is time-consuming, requires a large area, and involves a lot of manual labor. Therefore, it is necessary to develop a cooling device for dehydrated onions to cool them after drying. Utility Model Content

[0003] To address the above technical problems, this utility model provides a cooling device for dehydrated onion production.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a cooling device for dehydrated onion production, including a cooling tank, with an inlet pipe connected to the top and an outlet pipe connected to the bottom of the cooling tank, including a cold air blower, with an air nozzle connected to the bottom of the cooling tank, the cold air blower connected to the air nozzle through an air duct, an air pump installed on the air duct, a deodorizing pipe connected to the top of the cooling tank, an activated carbon layer installed inside the deodorizing pipe, a motor fixedly connected to the middle of the cooling tank, the motor shaft passing through the cooling tank and fixedly connected to a scraper, a scraper plate fixedly connected to the lower part of the scraper, a first baffle valve installed on the inlet pipe, and a second baffle valve installed on the outlet pipe.

[0005] Furthermore, the cooling tank is fixedly connected to a bracket.

[0006] Furthermore, a filter screen is fixedly connected at the connection between the deodorization pipe and the cooling tank.

[0007] Furthermore, each of the vertically arranged nozzles is fixedly connected to a protective cover.

[0008] This utility model has the following advantages compared with the prior art:

[0009] This invention includes a cooling fan connected to a nozzle at the bottom of the cooling tank. The nozzle blows air into the cooling tank to cool the onion granules, and the air also lifts the onion granules, resulting in a more even cooling effect. A deodorizing pipe is connected to the top of the cooling tank, and the activated carbon layer inside the deodorizing pipe removes the odor from the dehydrated onions. A motor and scraper are also included. During discharge, the scraper scrapes the wall of the cooling tank to prevent the onions from sticking to the tank wall. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a schematic diagram of the bottom structure of the cooling tank of this utility model.

[0012] The components are: 1. Cooling tank, 2. Feed pipe, 3. First gate valve, 4. Motor, 5. Deodorizing pipe, 6. Activated carbon layer, 7. Filter screen, 8. Scraper, 9. Scraper blade, 10. Protective cover, 11. Air nozzle, 12. Discharge pipe, 13. Second gate valve, 14. Support, 15. Air cooler, 16. Air pump, 17. Air duct. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figures 1-2 The cooling device shown includes a cooling tank 1, with a feed pipe 2 connected to the top and a discharge pipe 12 connected to the bottom. It also includes a cold air blower 15, with an air nozzle 11 connected to the bottom of the cooling tank 1. The cold air blower 15 is connected to the air nozzle 11 through an air duct 17, and an air pump 16 is installed on the air duct 17. A deodorizing pipe 5 is connected to the top of the cooling tank 1, and an activated carbon layer 6 is installed inside the deodorizing pipe 5. A motor 4 is fixedly connected to the middle of the cooling tank 1. The shaft of the motor 4 passes through the cooling tank 1 and is fixedly connected to a scraper 8. A scraper 9 is fixedly connected to the lower part of the scraper 8. A first baffle valve 3 is installed on the feed pipe 2, and a second baffle valve 13 is installed on the discharge pipe 12.

[0015] For stable support, the cooling tank 1 is fixedly connected to a bracket 14.

[0016] To prevent onion pieces from sticking inside the deodorizing tube 5, a filter screen 7 is fixedly connected to the connection between the deodorizing tube 5 and the cooling tank 1.

[0017] To protect the nozzles 11, a protective cover 10 is fixedly connected to the outside of the vertically arranged nozzles 11.

[0018] The specific working process of this utility model is as follows:

[0019] The dried onion pieces are fed into the cooling tank 1 through the feed pipe 2. The first baffle valve 3 is closed, and the cold air fan 15 and the air pump 16 are turned on. The cold air is fed into the air nozzle 11 through the air pipe 17 and enters the cooling tank 1 through the air nozzle 11. The cold air cools the onion pieces. At the same time, the cold air blows the onion pieces, causing them to float in the cooling tank 1, making the cooling more uniform. Meanwhile, the exhaust gas is discharged from the deodorization pipe 5, and the activated carbon 6 adsorbs the odor in the exhaust gas.

[0020] When the cooling is complete and the onion pieces need to be discharged, open the second gate valve 13 and discharge the onion pieces from the discharge pipe 12. After most of them are discharged, turn on the motor 4 and the scraper 9 will rotate to scrape the onion pieces off the tank wall and discharge them from the discharge pipe 12.
