Hulling and separating all-in-one machine for rice processing

Abstract

The invention discloses a hulling and separating all-in-one machine for rice processing. The machine comprises a hulling box, a feeding hopper, a hulling rubber roller, a material guiding inclined plate, a material guiding hopper, a winnowing hopper, an ascending fan impeller, a material uniformizing box, a V-shaped material guiding plate, a material uniformizing opening, a canvas soft connector, a uniform feeding opening, a separating box, a rice discharging opening, a brown rice discharging opening, a rice husk discharging opening, an air inlet duct, a dust removing box, air supply fan blades, a drawing frame, a molecular sieve honeycomb plate, a fixed support and an angle adjusting rotary knob. According to the invention, a traditional split type structure is replaced with an integrated structure, and the hulling process and the separating process are integrated into one process, so that the processing flow of rice is simplified, the conveying frequency of materials is reduced, the manpower is saved, the falling risk of the materials is reduced, and the processing efficiency of the rice is improved; and a vortex winnowing mode is used for replacing a traditional direct-current winnowing mode, so that the winnowing strength of the all-in-one machine is enhanced, the residual quantity of rice hulls in brown rice is reduced, and the winnowing effect of the all-in-one machine is improved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to an integrated machine for shelling and separating rice. Background technique [0002] Rice, also known as rice, is a food made from rice after cleaning, husking, rice milling, and finished product finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also the main food for people in most parts of China. At present, in the rice processing process, rice hullers are generally used to remove the hulls from the rice, and then the unhulled rice is removed from the hulled brown rice by a paddy separator. [0003] However, this split structure inevitably increases the number of materials to be transported, the labor intensity of personnel is high, the materials are easy to fall, and the processing efficiency of rice is reduced. Most of them adopt the direct-flow air separation method, and the air separatio...

Problems solved by technology

[0003] However, this split structure inevitably increases the number of materials to be transported, the labor intensity of personnel is high, the materials are easy to fall, and the processing efficiency of rice is reduced. Most of them adopt the direct-flow air separation method, and the air separation is not strong enough to separate the rice. The shed husks are completely removed from the material, which affects the wind selection effect of the rice. At the same time, the inflowing air is not dedusted during the wind selection process, and the rice processing sites are generally dusty environments, resulting in dust after wind selection. Impurity pollution affects the processing accuracy of rice
