Description

Technical Field

[0001] This utility model relates to cooling rice husks, and in particular to a rice husk cooling device. Background Technology

[0002] Rice husks, a common auxiliary material in brewing, must be steamed before use to remove pentosans and pectin, preventing the formation of off-flavors in the raw liquor. However, rice husks must be cooled before use; hot rice husks must never be mixed with other ingredients. Therefore, traditional brewing methods typically involve artificially cooling the husks naturally before bagging and storing them for later use. However, this method is inefficient and the cooling effect is not ideal. Utility Model Content

[0021] like Figure 1 and Figure 2 As shown, a rice husk cooling device includes a wind chamber 2 extending along the rice husk conveying direction. A chain conveyor mechanism is installed inside the wind chamber 2. Several exhaust fans 4 are installed on the side wall of the wind chamber 2, and the air inlets of the exhaust fans 4 are connected to the inner cavity of the wind chamber 2. A feeding box 3 is also provided at the top of the wind chamber 2. An opening slot communicating with the inner cavity of the wind chamber 2 is opened at the bottom of the feeding box 3. Several air inlets 5 are opened on the chain plates of the chain conveyor mechanism, and the advancing chain plates 11 of the chain conveyor mechanism slide in the opening slot. A hopper 6 is provided at the discharge end of the feeding box 3. In this embodiment, the hot rice husk is located on the chain conveyor. When in use, the exhaust fan 4 operates on the process chain plate 11, causing cold air from the outside to continuously enter from the top opening of the feed box 3, then through the gaps between the hot rice husks, and finally into the air chamber 2 through the air inlet 5 of the process chain plate 11. Under the action of the wind speed, the heat on the hot rice husks is carried away, causing the hot rice husks to cool down. The hot air entering the air chamber 2 is then drawn away by the exhaust fan 4 and finally discharged through the air outlet of the exhaust fan 4. Moreover, due to the operation of the exhaust fan 4, a negative pressure is formed in the air chamber 2, which causes the cold air from the outside to be drawn into the air chamber 2, thereby preventing the rice husks from being blown away.

[0022] In this embodiment, the chain conveyor mechanism is existing technology, specifically, as shown below. Figure 1 and Figure 2As shown, the chain conveyor mechanism also includes rollers and a drive motor 1. Rollers are installed at both ends of the air chamber 2, and the chain plate is wrapped around the two rollers. The drive motor 1 is installed on the outside of the air chamber 2 and is connected to one of the rollers. When the drive motor 1 works, it can drive the chain plate to rotate, thereby moving the chain plate 11 to realize the conveying of hot bran. During the conveying process, the exhaust fan 4 continuously evacuates the air chamber 2, allowing the outside cold air to continuously carry away the heat of the hot bran, thus cooling it down until the temperature of the hot bran meets the requirements of the next process. Therefore, in this embodiment, the length of the air chamber 2 can be set according to the actual situation to ensure that the temperature of the bran shells leaking from the hopper 6 meets the requirements. Of course, in this embodiment, multiple exhaust fans 4 are provided on both sides of the air chamber 2 so that the operator can select the appropriate exhaust fan 4 according to the actual situation to achieve the cooling of the hot bran.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, several support wheels 12 are also installed on the inner bottom of the feed box 3. The support wheels 12 are spaced apart along the husk conveying direction. The process chain plate 11 is placed on the support wheels 12. Through the support rollers, the horizontal conveying of the process chain plate 11 can be ensured, which ensures the reliability of husk conveying. Moreover, the process chain plate 11 is slidably engaged with the opening groove. Under the restriction of the opening groove, the process chain plate 11 can also be prevented from running off-center, which further ensures the reliability of husk conveying.

[0024] In this embodiment, to ensure the uniformity of the hot bran entering the feed box 3, such as... Figure 1 As shown, a temporary storage mechanism is also provided on one side of the air chamber 2. The temporary storage mechanism includes a support frame 7, on which a temporary storage frame 9 is installed. A material discharge port is opened at the bottom of the temporary storage frame 9. A plate feeding mechanism 8 is also installed on the support frame 7. The plate feeding mechanism 8 is located below the temporary storage frame 9. The discharge port 10 of the plate feeding mechanism 8 is located above the feed box 3. The steamed hot bran is first piled in the temporary storage frame 9. Then the plate feeding mechanism 8 works to transport the hot bran to the feed box 3. After the hot bran cools down, it is discharged from the hopper 6.

[0025] In this embodiment, as Figure 1The top and bottom of the temporary storage frame 9 are open, which facilitates the loading and unloading of rice husks. The top of the progress chain plate 11 of the plate conveyor mechanism is flush with the bottom of the temporary storage frame 9. The bottom of the side wall of the discharge end of the temporary storage frame 9 is provided with a discharge port 10. When the plate conveyor mechanism is working, it can drive the rice husks to move, thereby bringing the rice husks out from the discharge port 10. In actual use, the height of the rice husks piled in the temporary storage frame 9 is higher than the height of the discharge port 10 most of the time. Therefore, by setting the discharge port 10, the thickness of the rice husks brought out from the discharge port 10 is basically uniform, thereby ensuring the consistency of the feeding of the feed box 3, and thus making the thickness of the hot rice husks on the progress chain plate 11 basically uniform, thereby ensuring the reliability of the cooling of the hot rice husks.

[0026] In this embodiment, an insert plate for adjusting the size of the discharge port 10 is also installed on the side wall of the discharge end of the temporary storage frame 9. Specifically, a slot can be opened on the discharge end of the temporary storage frame 9, and an insert plate can be installed in the slot. By adjusting the position of the insert plate in the slot, the height of the discharge port 10 can be changed.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
