Spinning Cone Column Aroma Recovery System Machine Equipment

1. Liquid material can pump directly into the CFDS system, crushed into solid materials, first of all, about 10 to 60 mesh, according to certain ratio of solid and liquid blending into liquid slurry, continuous pumping CFDS system.

2. Liquid material after heat exchanger preheating first, heating to the extraction temperature into the rotating cone distillation tower. Under the action of centrifugal force, along the rotating cone up thin film flows, then under the action of gravity flow down the fixed cone to the next rotating cone; Clean water vapor in direct contact with the material, after a number of fixed cone and rotating cone, which extended the flow distance, Completely extracted volatile chemicals, after the secondary condensing, get the essence of concentrate.

3. Will receive the essence of concentrate again after CFDS system, can obtain high concentration essence and essential oil.

The Flavourtech Spinning Cone Column is a stripping column in which steam separates volatile compounds from liquids or slurries under vacuum.

The column itself is a vertical, stainless-steel vessel with a central rotating shaft. It contains a series of alternate rotating and stationary cones, the rotating cones attached to the shaft, the stationary cones fixed to the wall of the column.

The feed material, from which the volatile compounds are to be separated, is fed into the top of the column. This material, either liquid or slurry, flows as a thin film (approximately 1mm film thickness) down the upper surface of the first stationary cone. It then drains through the outlet of the stationary cone on to the base of the spinning cone immediately below. Centrifugal force, generated by the rotation of the cone, causes the liquid to flow upwards and outwards across the upper surface of the spinning cone, again as a thin film.

This film breaks up as it moves from the lip of the spinning cone; the liquid is then guided downwards on to the next stationary cone, and the cycle is repeated. In this manner, the liquid works its way, cone by cone, from top to bottom of the column.

At the same time as liquid is flowing down the column, stripping steam (vapour) is introduced into the base of the column. The vapour flows upwards, across the surfaces of the volatile-rich liquid films, separating (or stripping) the volatile compounds from the liquid. Fins on the undersides of the rotating cones promote turbulence in the vapour stream, increasing mass transfer efficiencies. Figure 3 illustrates the flow of liquid and vapour through the column.

The temperature and flow rate of the stripping steam can be controlled. The ability to control these parameters allows different aroma profiles to be captured from the same raw material to produce different aromas for multiple markets or products.

The vapour, which is now steam mixed with the volatiles stripped from the product, flows out of the top of the column and passes through a condensing system which captures the volatiles in a concentrated liquid form. The remaining liquid or slurry is pumped out of the bottom of the column.
