Recently we have had one Nigerian customer from Kano city, who ordered one 40ft container MPG 14.5 rice polishing machine. The MPG 14.5 rice polishing machine is also called the MPG 14.5 rice mist polisher. One 40ft container can hold 9 sets MPG 14.5 rice mist polisher.
MPG 14.5 rice polishing machine can make the white rice more beautiful, as below photo.
MPG 14.5 rice polishing machine add water pipe and air pump, when water and air meet inside, there will be mist, the mist can make the rice surface more beautiful. Rice Polishers let the rice be of higher quality and can sell rice at a higher price.
A rice polishing machine is used after the rice mill machine or after the rice grader machine.
All rice mill plants can add a rice polishing machine. The polishing machine can use a 22 to 30kw electric motor, and the capacity can reach 1.5-2 tons per hour.
What is a Rice Polisher?
A rice polishing machine is an indispensable tool in the finishing process of brown rice. It can effectively remove the bran powder on the surface of the rice grains and make the starch on the surface of the rice grains gelatinized, thus presenting a better good commercial appearance effect. It is used in rice processing plants widely.
1. Improves the appearance of rice:
The surface of milled rice becomes smooth and clean, leading to Enhanced commercial value.
2. Improves the quality of rice:
The residual bran absorbs moisture and helps microorganisms to develop. By removing this residual bran, the Hongjia rice polisher gives the rice a longer shelf life.
How Does a Rice Polisher Work?
In the polishing process, workers should remove the broken rice and the bran, and then spray water on the surface of the rice to polish it to decrease the cohesion between endosperm and bran. For takes little time in the rice polishing process, we do not need to worry about its moisture content after spraying water.
What Is The Working Principle of Rice Polishing Machine?
Polishing and buffing are finishing processes for smoothing a workpiece's surface using an abrasive and a work wheel or a leather strop. The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; It is also called rice polishing.
After the brown rice enters the polishing chamber, it is sprayed with water and enters the polishing chamber of the polishing machine. Under certain pressure and temperature, the surface of the rice grain is polished by friction, and the surface of the rice grains forms a gelatinized layer with a thickness of 20-50 microns.
Rice polishing can not only remove the floating sugar on the surface of rice grains but also play a role in pre-gelatinizing and gelatinizing the surface of rice grains. The starch gelatinization makes up for cracks, to obtain a bright and clean appearance and improves the storage performance and commercial value of rice. Therefore, rice polishing is very necessary.
What are The Main Structure and Characteristics of a Rice Polishing Machine?
The main structures of various types of rice polishing machines are similar. Generally, they are mainly composed of a spraying part, a polishing part, a water supply system, and a blowing mechanism. The characteristics and functions of each part are as follows:
Spraying water part: This part is mainly composed of the nozzle, nozzle cleaner, water mixer, feeding screw, stirring roller, etc. When the material passes through the flow meter, the flow rate is measured, thereby controlling the amount of water added.
Polishing part: The polishing part is the core part of the rice polishing machine, which is composed of a feeding screw, a polishing roller, an octagonal sieve tube composed of eight rice sieves, and a discharge pressure gate. The polishing roller is divided into iron roller and sand roller according to the nature of the material. The design should make it clear that the linear speed of the sand roller is higher than the linear speed of the iron roller (the linear speed of the iron roller is about 5m/s, the polishing pressure is higher, and the average value is 0.1MPa. The linear speed of the sand roller is about 15m/s, the polishing pressure is low, and the average value is 0.02MPa).
Water supply system: The water supply system consists of a flow meter, a pressure-reducing valve, a solenoid valve, and a control box. It is used to supply water to the water part and adjust the water supply amount according to the material flow rate.
Air-blowing mechanism: The air-blowing mechanism is composed of a high-pressure fan and an air inlet sleeve. The fan is directly installed on the air inlet sleeve, and the windblown from the fan enters the hollow shaft through the air inlet sleeve through the shaft hole and then sprays into the polishing room from the polishing roller spray groove.
