Rota-Cone® Vacuum Dryers are one of the most energy efficient, gentle and cost effective methods for drying solids to very low moisture levels. Because of the reduced vaporization temperatures possible under vacuum, Rota-Cone® Vacuum Dryers are ideal for drying heat-sensitive products including food ingredients and pharmaceuticals. Rota-Cone® Vacuum Dryers are also ideal for developing the deep vacuum and temperatures necessary for solid-state polymerization of polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). Dryers capable of temperatures up to 600°F are possible for drying or reacting applications. The clean double-cone or V-vessel shape provide gentle unobstructed tumbling of the solids and complete discharge with minimal hang up points. Vacuum leakage is minimized because there is only one seal on the vacuum line. The open design makes both visual inspection and CIP simple. Rota-Cone® Dryers are also rugged enough to blend and dry powdered metals with bulk densities up to 300 pounds per cubic foot. Horizontal Rotary Vacuum Dryers extend the range of drying applications by starting with slurries or pastes.

MoreThe Rotary cone vacuum dryer as the name suggest is used to produce homogeneous solid-solid mixture. The biggest advantage of the equipment is that it doubles up as a dryer along with a blender. Even hydroscopic material upto 22% moisture can be dried along with blending. The entire operation is under vacuum and a jacket is provided for heating or cooling depending upon the process required. A baffle plate along the centre of the body ensure even mixing during the rotation of the blender cones.
The dryers also come with choppers to ensure breakage of any lumps formed . There are 2 choppers that are positioned diagonally opposite sides of the cone ensuring even chopping of lumps.
Examples of materials or substances mixed in this way include pharmaceutical granules, semolina flour, seeds, starch, coffee beans and ground coffee, cocoa, chocolate flakes or granules, powdered milk, baby food, preparations to make dehydrated soups and creams, leaf waxes, detergent granules, soap flakes, artificial fertilizers, plastic in powder, ground or pellet form, fibreglass, etc.
