Effect of different husking and whitening machines to rice kernel varieties Abasiya and Mushkhab 1 for both seasons 2006, 2007

الملخص EN

The research comprised two experiment of two types of bleaching machine H- jetpealier and Satak rice machine and four types of Crunches machineH-Abrasive bleaching , RizharRice machine, Rice Daiachi machine and BilRookHuiter Hambubgon two rice varieties Abasiya and Mushkhab 1, under three moisture level 10-12 % , 12-14 % and 14-16 % for both seasons 2006 and 2007, The properties that are studied for bleaching machines were, percentage of bleached rice, percentage of head of rice and breakage percentage .The properties studied for Crunch machines were;.

percentage of total extraction, percentage head of rice and breakage percentage.

The results showed that the H-jetpealier was significant superior compared with Satak rice machine in all properties that studied for both seasons.

As for the weighted moisture content of rice kernel showed that the weighted moisture content 12 to14 % was significant superior in properties bleached rice and Percentage of the head of rice while the weighted moisture content 14 to16 % was significant superior in Breakage percentage and hulls percentage , for both seasons.

In the second experiment the Crunch machine was significant superior HAbrasive bleaching in all studied properties compared with other Crunch machines for both seasons.

As for the weighted moisture 12 to14 % was significant superior in studied properties Percentage of total extraction and Percentage head of rice.

while the weighted moisture content 14 to16 % was significant superior in breakage percentage for both seasons.
