Screen basket and cam distance of rice polisher
influences the degree of polishing. The screen basket covering the cam
rolls allows a pre-determined distance between them, with a greater
distance (i.e. a wider chamber) reducing the degree of polishing.
Rotational speed determines the degree of polishing. A higher rotational
speed increases the number of individual impacts, which results in a
higher degree of polishing. However, it also increases the amount of
rice breakages. Air suction is used to compact and cool the rice. If
the volume of air used is excessive, it can reduce the compactness and
the effectiveness of the polishing process, thus reducing the shine on
the rice.

Whole green gram was milled to obtain straight run flour,
protein-rich fraction, fiber-rich fraction and protein fiber-rich
fractions which were subsequently used for bread formulations. While the
protein content of straight run flour was 25.7%, that of protein-rich
fraction increased to 29.8%. Similarly the fiber content of straight run
flour was 8.2% and increased to 68.5% in fiber-rich fractions. Hence
differential milling can be used to separate specific constituents of
grains as desired which in turn can be used for product formulations.

Rice is a major contributor to the human diet, with half of the
world’s population depending on it to meet their daily caloric
requirements. However, this staple cereal lacks β-carotene (provitamin
A) and has insufficient iron, zinc and other nutrients in the endosperm
(polished grains) to meet dietary requirements. Biofortification of rice
endosperm for essential nutrients can have a significant positive
impact on global human health. In order to provide 30% of dietary
estimated average requirement (EAR) of iron, 15 μg/g DW iron should be
present in polished rice grains, while 28 μg/g DW of zinc can provide
40% of the EAR.

rice whitener
is used for one pass paddy milling into white rice and also for
crushing rice bran into fine bran. Suitable for household use and mobile
or moveable users. Suitable for processing  both Japonica rice and
Indica rice types. Small volume, light weight and low power usage.
Compact structure, convenient operation and maintenance; safe and
reliable operation.
