Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rice cooling bins, and in particular relates to a rice cooling bin for rice processing. Background Art
[0002] The rice processing process generally involves multiple steps, including dehumidification, impurity removal, husking, separation, bran removal, rice grading, polishing, color sorting, and finished product packaging. After husking, separation, bran removal, and grading, the finished rice is often quite hot. If the hot husked rice is directly fed into the polishing machine for polishing, it will often break the rice grains and produce a poor appearance. Furthermore, the moisture in the husked rice must evaporate, otherwise the storage life of the finished rice will be affected. Therefore, the husked rice must be cooled to around 20°C before polishing before proceeding to the next steps.
[0003] Most of the existing technologies use a rice cooling bin to cool the rice. The existing rice cooling bin generally adopts a natural cooling method, which has a slow cooling speed and a long cooling time. At the same time, the water in the rice is not evaporated sufficiently, which affects the quality of the finished rice.
[0004] In response to the above problems, the invention with patent publication number CN111229356A discloses a cooling rice bin, which includes a bin body consisting of a cooling bin, a discharge bin and a bin cover; an exhaust port is provided on the upper side of the cooling bin, a discharge port is provided at the bottom of the discharge bin, and a feed pipe is provided in the middle of the bin cover; a plurality of compressed air cooling pipes are provided in the bin body, extending vertically downward from the outside of the bin cover into the bin body, and the upper ends of the compressed air cooling pipes are connected to a compressed air generating device provided outside the bin body through compressed air pipes, and the compressed air cooling pipes located in the middle and lower parts of the bin body are provided with a plurality of through holes for exhausting air into the bin body, and the diameter of the through holes is smaller than the diameter of the rice grains; the compressed air generating device includes an air compressor, an air storage tank, a filter and a dryer connected in sequence through compressed air pipes; the dryer is connected to the compressed air cooling pipes through compressed air pipes.
[0005] The above invention can accelerate the cooling speed, improve work efficiency, and fully evaporate the moisture of the hulled rice, without introducing oil, gas, and dust, thereby improving the quality of the finished rice. However, this invention is implemented using a feed pipe, an upper dispersion plate, and a lower dispersion plate. The rice enters the cooling bin from the feed pipe, falls on the upper dispersion plate, and spreads out in all directions. It slides along the grooves of the upper dispersion plate and falls onto the lower dispersion plate. It continues to spread out in all directions, slides along the grooves of the lower dispersion plate and is dispersed within the bin, preventing the rice from falling below the dispersion plate. At the same time, the compressed air cooling pipe is distributed in a multi-ring ring shape within the bin, centered on the central axis of the bin. When the rice is dispersed, the compressed air cooling pipe will block the rice, resulting in uneven distribution of the rice within the cooling bin. Utility Model Content
