The paddy separator
is provided with an adjustment device for the table, which can be
adjusted at any moment in simple manner, and is provided with a feed
device, the use of which enables the second condition as to the
distribution of the material among the single chambers.

A paddy
separator according to thls invention with the improved adjustment
device that lie the table of the paddy separator supported in an
oscillating and well rnown manner on supports caused to vibrate by means
of the eccentric, or in any other desired manner, and provided with
throwing or projecting lates which throw to and fro the materia getting
into the single chambers and thus separate it so that it falls out from
the outlet openings 6 separated in accordance with'its specific gravity.
The material gets into the chambers from a feeding trough hand-wheel
which is into which it is introduced by means of a funnel or hopper or
in some other manner.

Previous study showed that rotary sifter
broken rice separators needed improvement both in the separation
accuracy for large and small broken kernels and in the separation
precision for small broken kernels and foreign materials. A rotary
sifter, alter-natively called a plan sifter or swing sieve, is a compact
hexahedral steel box swinging circularly on horizontal plane and
contains a vertical stack of six to eight screen trays with different
mesh sizes. Judging from this configuration, the rotary sifter broken
rice separator has little theoretical soundness because effective broken
rice separation should be done by the kernel length not its width.

The paddy husker
performance of different rubbers was compared for changes in the
applied normal load. It was found that grains rotate between the rubber
counterfaces on initial motion before being husked. In addition, harder
rubbers were found to husk a higher proportion of entrained grains at
lower applied normal load. By measuring the coefficient of friction
between rice and rubber samples, the shear force required to husk a
given percentage of grains could be calculated and was shown to be
constant regardless of rubber type.

China-zjlg is based on
high-grade and high-end market, products meet industry standards, mainly
exported to Southeast Asia, Africa, the Middle East, Europe, South
America and other countries.
