Rice processing equipment and its working principle

Rice processing equipment is a type of grain processing machine that removes glumes from rice to produce polished rice. The commonly used ones include the sand table luxury thresher and the rubber roller dehusker. Two types of machines. The main working component of the disc shelling machine is a ring-shaped sand disc bonded to the cast iron disc. The upper plate of the upper and lower plates is fixed, while the lower plate is rotating and can move up and down. The upper and lower sand can be adjusted according to the size of the rice grains. The gap of the CD for rice processing equipment. The rolling distance should be less than the length of meters, but greater than the width and thickness of meters. The rice from the feeding hopper sends the grains through the central area of the upper sand tray into the lower sand tray. The centrifugal force generated by the rotation of the lower sand tray forces the grains into the old two trays. Circular artillery zone. Under the action of end face pressure and friction, it is approximately 75. 0% of rice can be husked, but it is easier to crush and collect. A lot. After shelling, the rice husk mixture is removed from the rice husks by the airflow through the rice husk separation device and then discharged from the machine. The outer diameter of the sand tray is 4001120mm, and the width of the annular shell removal zone is generally 1/61/7 of the outer diameter. The main working components of the rubber roller dehuller are a pair of horizontal rubber or plastic rollers bonded or covered with a rubber layer on a cast iron cylinder (see the figure). Two roller shafts are at the same horizontal plane or slightly different heights and rotate in opposite directions at different speeds. The position of one roller is fixed. It is set that the other roller can be moved so that the rolling distance between the two rollers can be adjusted. The rice is mixed into the glue through the drip pan (or the feeding roller and the drip pan).

The entire length of the rice processing equipment drum is uniformly fed between the two drums. Most of the rice husks are removed through the squeezing of the two drums and the tearing effect caused by the speed difference between the two drums, and then enter the rice husk separation device. Then, they are sucked in through the suction port at a wind speed of 45 meters per second, and the mixture of rice grains and polished rice is discharged from the discharge drip tray. There are two types of distance adjustment mechanisms for rice processing equipment: constant pressure adjustment and distance adjustment. Constant pressure regulation can be carried out by air pressure, hydraulic pressure or pressure. Among them, the pressure-type automatic tightening roller (roller gap adjustment) mechanism was developed as early as the 1960s. In order to maintain the linear speed difference between the two rubber rollers at the correct linear speed, China has also developed a transmission method that combines gearboxes and V-belts. The rice processing equipment, the rubber roller dehusking machine, features high husking efficiency and high precision. There is less broken rice, but when the temperature is high, the rubber rollers wear out and the production cost is high. The rubber roller dehusking machine is mainly used for removing and separating rice husks, and it is one of the main working machines in rice processing. This device enhances the effectiveness of functional shell removal technology, reduces consumption, and creates more economic benefits for users. Two. Working Principle: Through a pair of rubber rollers rotating at different speeds in opposite directions, the rice between the rollers is squeezed by the pressure of weight. The purpose of shelling is achieved through pressing, rubbing and tearing. When the dehulled materials pass through the rice husk separation chamber, they are subjected to the effect of wind force. The mixture was separated from the rice husks. The overall structure mainly consists of a hopper feeding device, a die head device, a rice husk separation chamber, a gearbox, a frame, etc. Four. Process Flow: Clean grains enter the flow regulation mechanism from the hopper and then pass through the drip tray into the luxury grain machine. Between the two rubber rollers in the head box, shelling is carried out. The mixture after shelling enters the rice husk through the fish scale drip plate for separation, and the rice husk passes through.
