Hydration drying process

Claim 2

A process for drying a solids-containing aqueous product comprising the steps of: adding the aqueous product to a pre-determined quantity of particulate anhydrous alpha-dextrose and aqeous product; hydrating said particulate anhydrous alpha-dextrose with the aqueous component of the aqueous product by repeatedly agitating the particulate anhydrous alpha-dextrose and the aqueous product in a violent manner, whereby a substantial portion of the anhydrous alpha-dextrose is hydrated to alpha-dextrose monohydrate by the water in the aqueous product; and maintaining the temperature of the hydrating particulate anhydrous alpha-dextrose and aqueous product at or below 50° C. by allowing the anhydrous alpha-dextrose, aqueous product and alpha-dextrose monohydrate to remain quiescent after each agitating step whereby the heat generated by the agitating step is dissipated and the temperature of the alpha-dextrose monohydrate and the remaining anhydrous alpha-dextrose and aqueous product is maintained at or below 50° C.; wherein the hydration reaction is not inhibited by temperatures greater than 50° C. and a dry, free-flowing non-hygroscopic powder results; conditions are such that temperature would rise above 50° C. in the absence of admixing using intermittent, brief periods of substantially violent agitation; and formation of the dry, free-flowing non-hygroscopic powder is a result of water in the aqueous product forming alpha-dextrose monohydrate.
