Laboratory Rota Cone Vacuum Dryers

The Laboratory Rota Cone Vacuum Dryer is a high efficiency horizontal type drying equipment which integrates drying, vacuum decompression and mixed powder.
The Hywell Machinery lab 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.

Laboratory Rotary Vacuum Dryers Description

SZG Series Laboratory 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 laboratory rotary vacuum dryers is stable in operation. The special design guarantees two shafts realize good concentricity.

As for working medium, it main use the hot water for the lab vacuum dryer . For drying the adhesive raw material, we have designed specially a stirring plate buffer for you. 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. The smallest model of lab cone vacuum dryer may be 30L. but hywell machinery have the industrial Rotary Vacuum Dryer that  biggest volume reach 8000L.

Laboratory conical vacuum dryer construction material

Hywell machinery are able to offer our hw series laboratory 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. How do the lab rotary conical vacuum dryer works

the laboratory 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.

Laboratory Double Cone Vacuum Dryer Advantages

 hywell machinery szg series lab laboratory 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 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 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.

4. More complete discharge 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.

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 reduced cross contamination.

6. Easily inspected interior

All surfaces of the rota cone vacuum dryer can be inspected from one vantage point – the loading hatch. 

Rota Cone Drier Application

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