The high efficiency vacuum type de-stoning machine
Spectrum Vacuum De-stoners are used for separating heavier impurities such as stones, glass, metal etc., from food grains and seeds such as wheat, corn, peas, paddy, sesame, coffee, peanuts etc. as well as any other dry granular material.
The principle used is the stratification of the product into heavier and lighter fractions by forcing air through the bed of material. This is achieved by means of a Suction fan connected to the machine or by connecting the machine to a Central Aspiration System.
The vibration of the deck is achieved by means of unbalanced vibratory motors mounted below the product discharge end of the machine. The Vibrating deck pushes the heavier material in contact with the deck upwards towards the stone discharge spout. The lighter good material flows down the inclined, vibrating deck and exits through the clean product spout.
