Background

Rapeseed is an oil crop with high economic value and great development potential, and is the second largest source of vegetable oil next to soybean in the world. However, in the whole process from planting to finishing of rapeseeds, the main problem is that after the rapeseeds are harvested, the rapeseeds cannot be reasonably and fully dried due to weather reasons or the drying characteristics of the rapeseeds are not met after drying machine equipment falls behind, and the rapeseeds are easy to absorb moisture, sprout and mildew, and lose edible value and economic value.

The rapeseed drying equipment should have good sealing performance. In the rapeseed drying process, if the temperature of the seeds is too low, the precipitation is slow; however, if the temperature is too high, grease will overflow, drying is not facilitated, and fire may occur. Therefore, drying is an important link in the post-processing of grain harvesting, and the moisture content of the grain is reduced to safe moisture content through drying, so that the safe storage condition is achieved. At present, various grain drying machines are available in the market, and hot air is mainly used as a drying medium. At present, typical dryers mainly comprise a drum dryer, a fluidized bed dryer and the like, but most of the grain dryers are developed based on grains, have wide application range, lack pertinence and are poor in drying effect.

The drying characteristics of oil crops are different from those of common grains due to the fact that the oil crops contain rich grease, and the grain dryers cannot meet the requirements of rapeseeds on drying equipment and have the defects of incomplete drying, non-uniformity, large energy loss and the like.
