ROTATING DISC COLUMN

ROTATING DISC COLUMN

Innovation in taste technology

The Flavourtech Rotating Disc Column (RDC) is a continuous contacting device for the food and beverage industries. It can be used where well-defined contact times are necessary for the soluble components to be efficiently transferred from within solid particles to a liquid medium.

The RDC allows temperature, pressure and residence time to be controlled precisely to obtain near identical conditions for all parts of the mixture being processed, ensuring consistency in processing and ultimately, contributing to a superior end product.

In contrast to batch tank processing, the RDC’s continuous and automated process means labour, energy and overall production costs are reduced as time is not spent filling and emptying tanks.

Applications of the RDC include:

BENEFITS

PRODUCTION EFFICIENCY

The RDC’s unique design ensures the materials flowing through it are maintained in a state of continuous gentle agitation, preventing settling and the formation of static pockets.

QUALITY CONTROL

The risk of over-extraction or under-extraction is greatly reduced as the RDC offers precise control of temperature and residence time during the extraction process.

RETENTION OF NATURAL ROASTED COFFEE NOTES

The highest quality coffee aroma is separated from a continuous flow of coffee slurry in Flavourtech’s Spinning Cone Column (SCC). Use of the RDC allows efficient, high-temperature extraction of the coffee slurry, downstream of the aroma recovery step. The aroma is then added back to the final product efficiently producing a soluble coffee that incorporates authentic roast-and-ground aroma. In this way, it is possible to produce soluble coffee efficiently, and at the same time incorporate authentic roast-and-ground aroma.
