Description

Technical Field

[0001] This utility model relates to the field of rapid cooling technology for cottonseed meal, and in particular to a rapid cooling device for high-protein cottonseed meal. Background Technology

[0002] Cottonseed meal is a slightly reddish or yellow granular substance obtained from cottonseed through processes such as pressing and leaching. It is a major raw material for making feed, and it contains more than 40% crude protein.

[0003] A search revealed a rapid cooling device for cottonseed meal processing, application number CN202221740004.X. The device includes a housing; a feed hopper is installed at the upper end of the housing, a support is installed at the bottom end, a first conveyor belt is installed at the upper end inside the housing, and a second conveyor belt is installed at the bottom end inside the housing. A shaft is rotatably mounted inside the housing at both ends of the first and second conveyor belts, with one end of the shaft extending out of the housing and mounted on the front end of a motor. The motor is bolted to one side of the housing. Cooling pipes are installed inside the housing at the upper ends of both the first and second conveyor belts, and a water collection tray is installed at the bottom end of the cooling pipes. A drain pipe is installed at one end of the water collection tray. This invention continuously cools the material by introducing it through the first conveyor belt onto the upper side of the second conveyor belt and then exporting it through the second conveyor belt, thus improving the cooling efficiency.

[0004] The prior art describes a rapid cooling device for cottonseed meal processing. During use, the device only transports materials via a conveyor belt, causing the cottonseed meal to easily accumulate into layers. This results in insufficient heat exchange between the bottom layer of material and the cooling pipes, affecting the cooling effect of the cottonseed meal and making it impractical.

[0005] Therefore, we propose a rapid cooling device for high-protein cottonseed meal. Utility Model Content

[0028] Example 2

[0029] Based on Example 1, such as Figure 1-4 As shown, a feed hopper 3 is fixedly installed on the top right end of the sealing cover 8. A vibration motor 6 is fixedly installed on the left outer wall of the feed hopper 3. A first control valve 5 is fixedly installed on the right outer wall of the feed hopper 3.

[0032] The working principle of this utility model is as follows: When in use, the first control valve 5 is opened, and cottonseed meal enters the cooling chamber 1 from the feed hopper 3. The vibration motor 6 starts synchronously, using high-frequency vibration to prevent the cottonseed meal from agglomerating and clogging in the feed hopper 3. The filter screen 28 filters impurities (such as broken shells and granular clumps) from the cottonseed meal. The filtered cottonseed meal falls into the inner cavity of the cooling chamber 1. If the filter screen 28 needs to be cleaned, it can be rotated via the auxiliary ring 30 to disengage the threaded joint 29 from the threaded groove 27 before removal. The drive motor 10 starts, driving the rotating shaft 12 to rotate via the coupling. The spiral blades 14 rotate synchronously with the rotating shaft 12, longitudinally agitating the cottonseed meal and causing it to flow dynamically within the cooling chamber 1. Simultaneously, the fixed rod 13 rotates with the rotating shaft 12, and the vertical scraper 18... Under the elastic force of spring 26, it always adheres to the inner wall of cooling box 1, scraping off the attached cotton meal and preventing material adhesion; bottom scraper 15 rotates at the bottom of rotating shaft 12, scraping the bottom wall of the inner cavity of cooling box 1 to prevent cotton meal accumulation. Cooler 20 and liquid pump 19 start synchronously. Cooling water enters cooling pipe 16 through inlet pipe 21, absorbs heat from cotton meal and rises in temperature, and flows back to cooler 20 through outlet pipe 9 to cool down, forming a circulating cooling. External pipe 11 can be connected to other cooling medium sources (such as refrigerant) to expand the adaptability of the device to cooling scenarios. After the cotton meal is cooled, controller 2 triggers the second control valve 7 to open, and the cooled cotton meal is discharged through discharge pipe 4. Sealing block 17 ensures the sealing of the connection between discharge pipe 4 and cooling box 1 to prevent heat leakage during the cooling process.
