The Vertical Whitening Machines mod. AMV-60 and FTV-60 belong to the latest generation machines for whitening/pearling rice, wheat, barley, etc.

CHARACTERISTICS
- solidly and compactly built
- easy to use and service
- highly productive

Designed to be compact and easy to install, they take up limited space in any milling plant.
The Vertical Whitening Machines mod. AMV-60 and FTV-60 are designed to considerably reduce the space they take up in the plant and are less time consuming and cheaper to install. If the whole whitening line is installed, the use of elevators between the three units can be avoided thus reducing installation costs, maintenance costs and the surface area required for the plant. If elevators are not used between different units, the breakage rate is also reduced. By using this whitening line, you therefore obtain maximum productivity and can save time and money.
They are solidly built, easy to service and parts are easily replaced.
The machines’ new design and structure means they require servicing less frequently and worn parts can be easily replaced thus saving time.

WHITENING PROCESS
Due to the special configuration of the machines, a whitening line can be set up without using intermediate conveyor systems thus cutting down on space and reducing the breakage rate.
• The hulled rice enters the feed hopper on the first abrasive vertical whitening machine and is sent to the milling chamber along an endless screw steel conveyor; the abrasive effect of the grinders on the surface of the hulled rice removes the husk. The husk is discharged from the milling chamber grid and sucked up by a special vacuum system towards the outlet in the lower part of the machine. The milled rice then leaves the first whitening machine and is sent to the second friction vertical whitening machine.
• The rice is collected in the feed hopper of the friction vertical whitening machine and is then taken to the milling chamber along an endless screw conveyor. In the milling chamber of the second machine, the rice passes from bottom to top and is whitened again using friction. The husk removed from the grain of rice comes out of the milling chamber grids and is sucked up towards the outlet in the lower part of the machine while the processed rice is discharged to the upper outlet. A jet of high-pressure air in the milling chamber lowers the operating temperature in the chamber

  itself making the husk easier to remove from the grains of rice and reducing the breakage rate.
• The third milling unit is the same as the second one the only difference being that the friction whitening system is connected to a water atomizing system. The surfaces of the grains of rice are moistened for final cleaning and polishing. This special device mixes atomized water with the grains of rice in the milling chamber which makes the rice shinier and more uniform in appearance and protects it from becoming rancid during storage.
