Rapeseed drying and impurity removal device

Abstract

The invention relates to the technical field of drying equipment, and particularly discloses a rapeseed drying and impurity removal device. The rapeseed drying and impurity removal device comprises adrying barrel. A dust collecting cavity is formed in the top wall of the drying barrel, and dust absorbing covers are arranged on the top of the drying barrel. A vertical shaft is arranged in the drying barrel in a penetrating mode, and a plurality of stirring rods are arranged on the vertical shaft. Air bags are uniformly distributed on the inner wall of the drying barrel, a drying cavity is formed in the bottom wall of the drying barrel, and heat conducting pipes are arranged on the side wall of the drying barrel. Air outlet holes are uniformly distributed in the bottom of the drying barrel.Magnetic locating blocks are arranged on the air bags, and magnetic blocks are arranged at the ends of the stirring rods. An air cylinder is further arranged at the bottom of the drying barrel, an air inlet one-way valve and an air outlet one-way valve are arranged on the side wall of the air cylinder, and a feeding one-way valve and a discharging one-way valve are arranged on the side wall of the air cylinder. The air inlet one-way valve communicates with a heat supply device through a pipeline, the air outlet one-way valve communicates with the drying cavity through a pipeline, and the feeding one-way valve communicates with the dust collecting cavity through a pipeline. By the adoption of the rapeseed drying and impurity removal device, the problem that due to the fact that water vaporgenerated by rapeseeds in the drying process can condense again after touching the barrel wall of the drying barrel, drying of the rapeseeds cannot be sufficient is solved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a rapeseed drying and impurity removal device. Background technique [0002] Rapeseed, also known as brassica seed, is the fruit of the cruciferous crop - rapeseed. The mature rapeseed has a long shell, many pods and full grains. The content of oil in rapeseed is 37.5%-46.3%. It is one of the main oil crops and honey crops in China, and it is also one of the main varieties of raw materials for making oil. [0003] When the rapeseed is mature and ready to be harvested, due to the dehydration and shrinkage of the husk, it is easy to crack, so that the shelled rapeseed often contains more broken shells, which need to be sieved. In addition, the newly harvested rapeseed has a large water content. , if not fully dried, it is prone to mildew during storage, which will affect the quality of rapeseed. [0004] The current rapeseed dryer usually includes a drying barrel. A rota...
