The SB Series is an integrated machine that combines rubber hulling and polishing, offering a comprehensive solution for rice processing. The process begins with rice entering the machine through a vibrating screen, which removes stones, and a magnetic unit, which eliminates small metal pieces. The rice then progresses through the hulling chamber to remove yellow husks, followed by the winnowing, milling (where brown chaff is removed, producing white rice), and blowing chambers. This machine efficiently handles the entire process from cleaning and hulling to milling. It separately expels husks, chaff, blighted grains, and polished rice. Additionally, a jet blower is installed near the outlet for finished white rice, which not only reduces the rice's temperature but also separates chaff from the white rice, resulting in a much clearer final product.
Feature:
This machine embodies the best features of various rice-processing equipment. It is thoughtfully designed with a comprehensive understanding of the requirements, resulting in a rational and well-organized structure. The machine operates with minimal noise and offers ease of use and reliable control. Post-processing, the rice contains less chaff and fewer broken grains, with a cleanliness level that exceeds standard expectations. It is energy-efficient and highly effective in its operation, representing the new generation of Combined Rice Milling technology.

Structure and working principle:

The SB Series Rice Mill Machine features dual operational systems: rice milling and bran removal. Grains are introduced into the grinding chamber via the hopper, where they are milled by the grinding wheel. Following the milling process, the grains are expelled through the rice outlet. Portions of the shell and bran, removed during milling, exit through the sugar screen hole into the grinding chamber, while the remaining materials are expelled by the airflow of the bran remover as the grains are discharged from the rice outlet. The separated bran is then evacuated from the machine by the fan.
The whitening efficiency of grain is influenced by factors such as the grain size of the grinding wheel, the number of machine revolutions, the gap in the grinding chamber, the pressure, and the resistance level within the grinding chamber. The pressure in the grinding chamber can be regulated by adjusting the grain flow at both the inlet and outlet and by altering the length of the grain pushing wing. The resistance within the grinding chamber can be modified by adjusting the position of the female knife. Additionally, the bran removal effect can be managed by altering the position of the adjusting plate to change the airflow of the bran remover.
