Gyroscreen flour sifter - A better way to sift flour
In Big bakeries where production are very large and volume of flour to be screened is more then these vibratory gryoscreens are used with great success .
Sifters application was manually in many cases and rate of screening very slow now with these vibratory gyroscreen we can screen large amount of flour for process .PrincipleIt works on the pricnicple that when flour is subjected to vibratory motion the larger particles tend s to shift to periphery of the screen where the smaller particles drops to the next level . There are two or three layers of mesh of different sizes normally 38 , 36 , 34 , 32 as per the requirement .How it worksVibro screen are driven by a special type of vertically mounted motor having eccentric at the upper & lower end of the shaft.
Rotation of out of balance top weight causes vibration in Horizontal plane whereas the rotation of lower weight causes tilt & vibrations in vertical plane.
