ABSTRACT:
A whitening, polishing or pearling machine for grains and cereals and more particularly for rice, vertically disposed, composed of an integral chamber which has an entry or grain feeder, said grain being transported to a section where it is treated in order to whiten or polish it, the grain once treated being passed through a centrifugal extractor to collect the product, or to a regulating hopper which is connected directly to another machine exactly like the first in order to complete the treatment or to another process if the grain has now been totally polished.
The grain is treated by centrifuging by means of a rotor which casts it toward screens, raising it by the thrust of a feed screw which rubs the grains against each other, against the screens and also against work-intensifying knives located within the treatment section or chamber, driving out the particles of the flour produced during treatment to a discharge where they are collected.
The system of operation uses a blower which produces air under pressure which serves the function of cooling the grain which is heated by friction and at the same time drives the flour through the said screen.
The outstanding characteristics of the machine are those related to its vertical disposition and to the fact that in a single unit are included the moving system of whitening, transmissions, motors and the ventilation system.
The vertical disposition of the machine affords the advantage of eliminating elevators or stepped installations since the machine itself elevates the product during the process.
