Double Cone Vacuum Dryer

The double cone vacuum dryer is a high-efficiency horizontal type vacuum drying equipment that integrates drying, vacuum decompression, and mixed powder.
The Hywell Machinery lab model double cone vacuum dryer has a few advantages that make it suitable. the double cone vacuum dryer (lab scale) 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.

Double Cone Vacuum Dryer Description

SZG Series Laboratory model double cone 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 laboratory rotary vacuum dryers are stable in operation. The special design guarantees two shafts 

realize good concentricity.

As for the working medium, it mainly uses hot water for the double cone vacuum dryer. For drying the adhesive raw material, we have designed specially a stirring plate buffer for you. Let the 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 the inner shell; Under the 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 in 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 a 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. The smallest model of the lab double cone vacuum dryer may be 30L. but hywell machinery has the industrial rotary cone vacuum Dryer whose biggest volume reach 8000L.

Double Cone Vacuum Dryer Construction Material

Hywell machinery is able to offer a lab series rotary double cone vacuum dryer with contact parts to be built in ss304, ss316l, titanium, duplex stainless steel, etc. Electrical parts of the control system of the rotary vacuum drying machine can be adapted to the customer’s needs.


Double Cone Vacuum Dryer Application

The double cone vacuum dryer is suitable for vacuum mixing and drying of power and granule raw materials of the pharmaceutical industry, chemical industry, foodstuff industry, etc.


How Does Rotary Double Cone Vacuum Dryer Work

the lab rotary double-cone vacuum 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.


Double Cone Vacuum Dryer Advantages

Hywell Machinery lab series double cone vacuum dryer had the following advantages over conventional solutions. Vacuum dryers offer many benefits including:

1. Dry temperature-sensitive products because all liquids vaporize at a lower temperature at reduced pressures, it is possible to vaporize the liquids at very low temperatures.

2. Reduced energy since the evaporation of the liquid under vacuum occurs at a much reduce temperature, the temperature differential is increased without raising the temperature.

3. Safe for friable products the low speed at which double-cone vacuum dryers operate, just a few revolutions per minute, makes rota-cone dryers ideal for delicate and friable solids such as crystals, macromolecules, or agglomerated solids.

4. More complete discharge unlike agitated dryers, rota-cone dryers have the very little surface area and no agitator to trap product. The simple unobstructed 45-degree cone allows all products to freely discharge.

5. Low cross-contamination because there is only one moving part, the tumble dryer is an inherently simple and clean design, which improves yield and reduces cross-contamination.

6. Easily inspected the interior
