The Hywell Machinery 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 Dryer are ideal for drying heat-sensitive products including food ingredients and pharmaceuticals. The clean double cone 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. Rotary Vacuum Dryers are also rugged enough to blend and dry powdered metals with bulk densities. Horizontal Rotary Vacuum Dryers extend the range of drying applications by starting with pastes.

The Rota Cone Vacuum Dryer is a high efficiency horizontal type drying equipment which integrates drying, vacuum decompression and mixed powder.
The Hywell Machinery double cone vacuum dryer has a few advantages that make it suitable. It is an extremely gentle dryer/mixer for minimal particle size degradation. The drying phase is by vacuum with a solvent recovery system to allow for the recovery of the solvents that were used to dissolve the active ingredients. The discharge from the vessel is from the bottom of the cone by a full port valve. It also allows for the entire batch to discharge quickly with minimal residual material left behind.

SZG Series Rotating Vacuum Dryer is a new generation drying device developed by our factory on the basis of combining the technology of similar equipment. It has two connecting ways, i.e. belt or chain. Therefore rotary vacuum dryers is stable in operation. The special design guarantees two shafts realize good concentricity. It can carry out speed control and constant temperature control.
As for working medium, it may be thermal oil or steam or hot water. For drying the adhesive raw material, we have designed specially a stirring plate buffer for you. The biggest may be 8000L. Let heat source (for example, low pressure steam or thermal oil or hot water) pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell; Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can be realized; The raw material is under vacuum. The drop of steam pressure makes the moisture (solvent) at the surface of raw material reach the state of saturation and evaporate. The solvent will be discharged through vacuum pump and recovered in time. The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time.

For the heating method of the tray vacuum dryer, it can use the steam or hot water or heat transfer oil as heat source. However, the above heat sources cannot be provided by end user. Hywell machine can provide electric heating heat transfer oil furnace or electric heating hot water tank. Specific can be designed according to customers.
If the material contains a large amount of solvent or relatively expensive solvent. The vacuum drying equipment can optionally be equipped with a condensation recovery device, the condensor use to cool the solvent into a liquid through the condenser and recover it.
There are two types of vacuum dryer condensers in Hywell company. One is the traditional tube condenser. This condenser is made of seamless steel pipes that arranged inside the condenser cover. The outside of the tube is equipped with cooling fins to increase the condensation efficiency.
The other is a metal hose condenser. The condenser is undoubtedly a seamless metal hose wrapped inside the condenser. so the same heat exchange area, the outside size of hose wound condensor is smaller than the tube condenser and cost is also cheaper. now Hywell company almost use this kinds Hose wound tube condenser.

Hywell Machinery are able to offer our HW series Rotary Conical Vacuum Dryer with contact part to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. Electrical parts of control system of the drying machine can be adapted to the customer’s needs.
If some materials are highly corrosive need to be dried, such as materials with strong acid and strong alkali (PH <4 and >10). Hywell machinery's double cone dryer can be lined with enamel for the contact material parts to increases the corrosion resistance of equipment (inorganic vitreous materials are melted and condensed on the base metal and A composite material that bonds firmly to metal). The drying equipment industry usually named lined with enamel dryer as enamel double cone vacuum dryer or lined enamel dryer.

The double-cone dryer is a double-cone rotary tank. When the tank is in a vacuum state, steam or hot water is passed into the jacket for heating, and the heat is in contact with the wet material through the inner wall of the tank. The vapor that evaporates after the wet material absorbs heat is evacuated by a vacuum pump through a vacuum exhaust pipe. Since the tank body is in a vacuum state, and the rotation of the tank body causes the materials to continuously turn up and down, inside and outside, the drying speed of the materials is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
Hywell machinery SZG series Double cone vacuum dryer had the following advantages over conventional solutions. Vacuum dryers offer many benefits including:
Because all liquids vaporize at lower temperature at reduced pressures, it is possible to vaporize the liquids at very low temperatures.
Since the evaporation of the liquid under vacuum occurs at a much reduce temperature, the temperature differential is increased without raising the temperature.
The low speed at which tumble dryer operate, just a few revolutions per minute, makes Rota-Cone Dryers ideal for delicate and friable solids such as crystals, macromolecules or agglomerated solids.
Unlike agitated dryers, Rota-Cone Dryers have very little surface area and no agitator to trap product. The simple unobstructed 45 degree cone allows all products to freely discharge.
Because there is only one moving part, the tumble dryer is an inherently simple and clean design, which improves yield and reduced cross contamination.
All surfaces of the Rota-Cone® Vacuum Dryer can be inspected from one vantage point – the loading hatch.
Active pharmaceutical ingredients, drugs and toxic chemicals are easily isolated in a vacuum dryer. Loading and discharging connections can be automated, sealed and purged for worker protection. The closed system also assures the maximum collection of solvents is achieved, protecting operators and the environment.
The Rota-Cone Vacuum Dryer is ideal for avoiding oxidation of chemical and with the addition of an inert gas purge, an oxygen free environment can be maintained.
We are able to offer our rotary cone vacuum dryer with contact part to be built in Carbon steel, SS304, SS316/316L, Titanium, Duplex stainless steel, etc. Standard of internal and external finish can be adopted to the customer’s needs.
cone vacuum dryer can have a variety of feeding & discharging methods that match the demands of the filling & production line.
Rotating cone vacuum dryer have a drive system by geared motor,belt or chain transmission, etc.
Double cone vacuum dryer are available with jackets for heating / cooling operation.
Dimensions of our rotary vacuum dryer can be defined according to customer’s requirements.
