Guar Gum Plant

Guar Gum Manufacturing Process:

Depending upon the requirement of end product various processing techniques are used. In India the commercial production of Guar gum is normally undertaken by using process of roasting, differential attrition, sieving and polishing.

The stage wise process of manufacturing food grade guar gum is as under. It is very important to select guar split in this process. The split will be screened to clean and then it will be soaked to prehydrate in a double cone mixer/Washing conveyor. Prehydrating stage is very important in the process as it derives the rate of hydration of the final product.

The soaked splits, which has reasonably high moisture content, will be passed through Flacker to take them. The flaked guar split will be predried in duct dryer. The dried guar flake will be ground to desired particle size in ultrafine grinder followed by drying of the material in flash dryer. The power will be screened through rotary screens to deliver required particle size. The oversize will be either recycle to main Ultra fine or regrind in separate regrind plant, as per viscosity requirement.

This stage helps to reduce the load at the grinder. The soaked splits are difficult to grind. Direct grinding generates more heat in the grinder which is not desired in the process as it results in insoluble or reduced hydration of the product. Through heating, grinding & polishing process the husk is separated from the endosperm halves and the refined Guar Gum split are obtained. Through grinding process the refined Guar split are then treated and converted into powder.
