The structural principle of the new combined rice milling machine is actually very simple. It is composed of a casing, a drum (with a spiral rack on the drum), a rice knife, a processing barrel, a rice sieve, etc. When working, the rice is poured into the hopper and the inlet knife is opened. It flows into the space between the whitening chamber and the drum. Due to the rotation of the drum, it is subjected to great extrusion force and friction, causing the chaff to fall off and grind very fine, make it white.

What is the structural principle of the new combined rice mill? The following is an introduction.

1. The structural principle of the new combined rice milling machine is actually very simple. It consists of a casing, a drum (with a spiral rack on the drum), a meterdagger, Processing barrel, rice sieve, etc. When working, pour the rice into the hopper and open the inletdagger, It flows into the space between the whitening chamber and the roller. Due to the rotation of the roller, it is subjected to a large squeezing force and friction force, causing the chaff to fall off, grinding the chaff very finely, and making it white. Under the constant rotation of the barrel, the rice grains are pushed to the source through the spiral rack, from whichdaggeroutflow. The chaff leaks from the rice sieve into the bottom of the casing, and the bran is processed into the feed required by the customer by mixing the bran portion.

2. The new combined rice mill mainly needs two adjustments, one is ricedaggerThe adjustment of the position, the second is the adjustment of the entrance and the exit. MetersdaggerThe adjustment is mainly to adjust the meter.daggerand the spacing between the cylinders. If the interval is large, the pressure in the rice milling chamber is low, the friction force of the rice in the barrel is not strong, and the rice cannot be finely milled, but the rice yield will be high. When the entrance is opened and the source is closed, the grain in the whitening chamber increases, and its pressure increases, resulting in beige and white, but more crushed grains. On the contrary, when the entrance turns down and the source turns up, the rice stored in the rice milling chamber Less, the pressure is reduced, and the rice is rougher.

According to the requirements of pressure and friction in the rice milling room, to grind rice with full particles, white color and good quality, you need to be reminded to adjust the interval between the rice knife and the barrel and enter and exit.daggerThe opening and closing degrees are as follows.

(1) If the interval is appropriate, the interval should not be less than the transverse diameter of the particles, otherwise, the particles are easy to break; the interval should not be greater than the longitudinal diameter of the particles, otherwise, the crushed rice grains will be very rough. Moreover, the gap between the rice knives should be selected between the longitudinal and transverse diameters of the particles, and the gap between the rice knives should have a slight slope, that is, close todaggerThe gap at one end should be slightly larger so that the rice milling is more complete.

(2) Import and export knives should be well coordinated. Generally, the opening degree can be controlled at 1/2 of the whole opening degree, up to 2/3. It is inappropriate for some established operators to take off the imported knives and let all the imports open. Because after all, there are too many rice grains, the pressure in the whitening room is too high, and the rotation resistance increases. If the knife fails to match for a while, the belt will slip, even jam the machine or damage the machine. During operation, the gap between the opening of the rice knife and the inlet knife should be adjusted according to regulations and then fixed. At this time, only the right hand needs to operate the outlet knife, and the left hand needs to extend out the lower end of the source to accept the rice grains, so as to check whether it, whether the beige is white, if it is broken much, open a large export knife, if it is rough, lower the source cutter, both must be taken into account until the rice milling quality meets the requirements.
