The necessity of most operators in the rice sector to produce higher quality product with longer shelf life capable enduring long storage periods, urged Sangati Berga to develop a polishing machine for rice that is capable of satisfying these requests. Traditional friction type whiteners do not remove the bran layers completely and often damage the rice grain surface by scratching it.
The fats present in the bran that remain adhering onto the rice, are subject to oxidation and could become rancid, with the risk of deteriorating the product and development of bad smells. Also bacteria and microorganisms could develop.
In the Horizontal Wet Polisher for Rice Type SBR POU 18/100, Sangati Berga applied an air draft with controlled moisture over the whitening process, which helps to avoid these situations and allow for producing sound white polished rice with suitable characteristics. The Horizontal Wet Polisher for Rice Type SBR POU 18/100 also allows for increasing the yield, compared to traditional friction machines, thanks to the minor friction existing among the grains being processed.
Features:
- Higher commercial value of the finished product;
- Higher easiness and safety for storage of the finished product;
- Enhancement of the successive processes (selection by color, granulometry, etc.).
