Abstract
An aqueous sucrose solution is evaporated continuously while being subject to vigorous mechanical agitation to produce a sucrose suspension which is spray dried immediately, after which the spray dried product is post-crystallized and post-dried. A complete recovery is obtained of the sucrose present in the solution, in a process which is simple and economical since injection of sucrose crystals in the drying gas in the spray drier is omitted.
Claims2
A method of evaporating and spray drying a sucrose solution, comprising evaporating the sucrose solution continuously while subjecting it to vigorous mechanical agitation, to produce a suspension of sucrose crystals in sucrose solution, spray drying in a spray drier said suspension without any preceding cooling-crystallization to achieve a material resembling wet snow and having a moisture content of between 0.5 and 5% by weight, wherein there is no recycling of sucrose crystals to the spray drier, and post-crystallizing and post-drying said material.
