The use of modern equipment in rice processing can improve effectiveness and efficiency and can also have a positive impact on the quality and quantity of processed products. Once the rice is harvested, the grain is processed through several stages using certain equipment or machinery to become rice.
The first stage of processing rice to rice is threshing stage by using thresher machine, second stage is the process of rupture of the skin using rice huller machine, and the last stage is grinding process by using rice polisher ).
CONVERSION STAGE
Threshing is the process of separation between grains and straw. In hybrid rice rice is generally first felled and then dried / dried, while for local rice varieties generally dry rice first and then threshed. The different stages of this process because hybrid rice is easily poisoned manually while on local varieties more difficult, so to merontokannya need thresher machine.
Threshing is usually done by using a semi mechanical thresher (thresher pedal) or mechanical thresher (power thresher). The use of mechanical thresher can increase the threshing capacity to approximately one ton of GKP per hour. It also reduces shrinkage depreciation rather than threshing in gebotan (5-8%) or traditional way.
LEATHER LEVEL STAGE
Skin damage is peeling the skin from seeds. Before milling, the grain should be cleaned first of all the impurities such as straw, wood, broken pieces of stone, metal and so on. Soft debris such as straw will reduce the milling capacity, while hard dirt like rock will damage the milling machine. The result of this stage is RICE LEATHER OR BROWN RICE. Rice seeds still have epidermis (aleurone and pericarp). The epidermis is commonly known as bran. The process of breaking the skin or separating the grain from the skin can use peeling machine or Rice Huller.
STAGNING STAGNING
Stages of process terakihir rice into rice is a grinding process, namely the process of peeling the epidermis so that the grains obtain clean white rice. The result of this process is white rice that is ready to be marketed. Grinding stage using rice bleach machine or rice polisher.
