Rice winnowing device based on magnetic field separating and screening technology

Abstract

The invention discloses a rice winnowing device based on the magnetic field separating and screening technology. The rice winnowing device comprises a machine body. A feeding hole is formed in the middle of the top end face of the machine body. A first flow guide plate cooperating with the feeding hole is arranged on the top wall of an inner cavity of the machine body. A separating and screening barrel cooperating with the feeding hole and the first flow guide plate is arranged on the upper portion of the inner cavity of the machine body. A first impurity discharging hole is formed in the upper portion of the right side end of the machine body. The inner side end of the first impurity discharging hole is connected with a flow guide hopper in a communicating manner, wherein the flow guide hopper cooperates with the separating and screening barrel. An air spray device is arranged in the middle of the right side wall of the inner cavity of the machine body. The air inlet end of the air spray device is connected with an air pipe in a communicating manner, and the other end of the air pipe penetrates the machine body and is connected to an air blower in a communicating manner. Multiplesupporting legs are evenly arranged on the edge of the bottom end face of the machine body. According to the rice winnowing device, through the arrangement of the separating and screening barrel and apermanent magnet, magnetic impurities in rice can be effectively removed; and through mutual cooperation of the air spray device and a second impurity discharging hole, rice hulls and other impurities in the rice can be winnowed out, the rice quality is greatly improved, and normal operation of the next procedure is facilitated.

Description

technical field [0001] The invention relates to the technical field of rice screening, in particular to a rice winnowing device based on magnetic field separation and screening technology. Background technique [0002] Rice, also called rice or paddy rice, is an edible grain, an annual herb plant, which likes temperature and humidity. It is commonly called "rice" or "millet" in southern China, and the hulled grain is rice. After cooking, it is called rice (speaking in northern China) or plain rice (speaking in southern China). Paddy is one of the main food crops in my country, with a long history of planting. Rice is not only a grain, but also a raw material for making wine and caramel. Half of the world's population eats it. Mainly in Asia, southern Europe and tropical America and parts of Africa. The total output occupies the third place in the world's food crop output, which is lower than that of corn and wheat, but it can maintain the lives of a large number of peopl...
