State of the art rice production facility

Levidia not only understands the raw material, but the individual drivers in the handling and production process – from receipt of freshly harvested paddy, all the way to the finished and packed rice

Levidia not only understands the raw material, but the individual drivers in the handling and production process – from receipt of freshly harvested paddy, all the way to the finished and packed rice

Drying

Rice from the field is harvested and threshed to produce what is most often called paddy rice or rough rice. Rice is usually harvested at about 18% to 24% moisture and must be dried down to about 12% to 14% so that it can be safely stored. Drying of the rice (including while in the field prior to harvest) is a critical component in regards to quality. Rice that is cracked during drying will have a lower percentage of head yield and will have a poorer quality after cooking. In Macedonia, the paddy rice is spread on some sort of concrete or pavement and raked over until dry.

Levidiagro invested in the grain dryer of 55 cu. mts. capacity where the paddy is dried with indirect heat, while passing through air chambers. This unit can also be installed near the paddy field, but is currently used as fixed unit at the Levidiagro premises.

Milling

Rice milling is the process of removing the husk and bran layer to produce white rice. Rice milling can be undertaken as a multistage process where rice passes through a number of different operations and machines from paddy to white rice.

The modern factory of Levidiagro aims to:
• produce edible rice that appeals to the customer- i.e. rice that is sufficiently milled and free of husks, stones, and other non-grain materials;
• maximize the total milled rice recovery out of paddy and minimize grain breakage

Many adjustments are automated for maximum efficiency and ease of operation. The whitener-polishers are provided with gauges that sense the current load on the motor drives which gives an indication of the operating pressure on the grain. This provides a more objective means of setting milling pressures on the grain. The state-of art color sorters provide the final separation of any impurities in color and variety by using camera and laser techniques.

Optical Sorting

A key component of the success in rice processing has been the growing demand and acceptance of Levidiagro’s leadership in optical sorting for rice. Offering a
comprehensive portfolio of fully automated rice optical sorters (Sortex) that allows rice processors to specify and deliver specific rice quality and sorting capacity that meets their exact output requirement.
