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 a vacuum, Rota Cone Vacuum Dryer is ideal for drying heat-sensitive products including food ingredients and pharmaceuticals. The clean double cone shape provides 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 of the rota cone vacuum dryer makes both visual inspection and CIP simple. Rota cone vacuum dryers are also rugged enough to blend and dry powdered metals with bulk densities. Horizontal rotary cone vacuum dryers extend the range of drying applications by starting with pastes.

The Rota Cone Vacuum Dryer is a high-efficiency horizontal rotary cone drying equipment that integrates drying, vacuum decompression, and mixed powder. This Rota Cone Vacuum Dryer is often named vacuum double cone dryer, rotary cone vacuum dryer, double cone vacuum dryer, double cone rotary vacuum dryer, or double conical vacuum dryer.
The Hywell Machinery double cone vacuum dryer has a few advantages that make it suitable. It is a highly 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 of the rotary cone vacuum dryer is from the bottom of the cone by a complete port valve. It also allows for the entire batch to discharge quickly with minimal residual material left behind.
If some materials tend to agglomerate during drying but are not sticky. This related material can be considered for our company's conical paddle vacuum dryer.

SZG Series Rotary 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 Rotary Cone Vacuum Dryers are stable in operation. The special design guarantees two shafts realize good concentricity. The Rotary Cone Vacuum Dryer can carry out speed control and constant temperature control.
As for the working medium, it may be thermal oil or steam, or hot water. For drying the adhesive raw material, Hywell has designed specially a stirring plate buffer for you. The biggest volume of Rotary Cone Vacuum Dryers 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 the 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 a 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 a vacuum pump and recovered in time. The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes of the Rotary Cone Vacuum Dryers are carried out unceasingly and the purpose of drying can be realized within a short time.

For the heating method of the vacuum double cone dryer, it can use steam or hot water or heat transfer oil as a heat source. However, the above heat sources cannot be provided by the end user. Hywell machine can provide electric heating heat transfer oil furnace or electric heating hot water tank for the vacuum double cone dryers. The specific heating method of the vacuum double cone dryers can be designed according to customers.
If the material being dried contains a large amount of solvent or relatively expensive solvent. This Rota Cone Vacuum Drying Machine can be equipped with a condensation recovery device. The condenser of Rota cone vacuum drying machines is used to cool the solvent into liquid through the condenser and recover it to reduce losses. Or the material being dried contains a lot of toxic solvents. In order to avoid the impact of toxic solvents on the environment, The Rota Cone Vacuum Drying Machines can also be equipped with a condensation recovery device to recover the toxic volume to reduce environmental pollution.
Hywell machinery has two types of vacuum drying condensers. The tube condenser of the vacuum double cone dryer is a relatively traditional condenser. The condenser is made from a plurality of seamless steel tubes arranged within the condenser shell. The seamless steel pipe is equipped with radiating fins to increase the condensation heat exchange area and thus increase the heat exchange efficiency. When the condenser is working, the cooling medium is input from the inlet of the condenser shell, and then the entire shell is filled with the cooling medium. The gas with the solvent is pumped out from the inside of the drying barrel of a vacuum double cone dryer by the vacuum pump, and then quickly condenses and becomes liquid through the seamless steel pipe soaked in the refrigerant, and then the condensed solvent liquid solvent is stored in the solvent storage tank. Other water vapors and a small amount of uncondensed solvent are discharged through the vacuum pump of the vacuum double cone dryers.
The other is a metal hose condenser. The condenser of the double cone vacuum dryer is undoubtedly the seamless metal hose that wraps around the inside of the condenser. Therefore, for the same heat exchange area, the outer side of the hose winding condenser is smaller than that of the tube condenser, and the cost is also cheaper. Now Hywell company almost all use this kind of hose around the tube condenser for the double cone vacuum dryers. When the condenser is working, the cooling medium is input from the inlet of the condenser shell, and then the entire shell is filled with the cooling medium. The gas with solvent is pumped out from the inside of the host by the vacuum pump of the double cone vacuum dryer, and then quickly condenses and becomes liquid through the seamless metal hose soaked in the refrigerant, and then the condensed solvent liquid solvent is stored in the solvent storage tank. Other water vapors and a small amount of uncondensed solvent are discharged through the vacuum pump of double cone vacuum dryers.

The rotary conical 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, and the drying efficiency of the rotary conical vacuum dryer 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. A double conical vacuum dryer offers many benefits including:
Because all liquids vaporize at a 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 double cone vacuum drying machines 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 the 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 reduces cross-contamination.
All surfaces of the Rota Cone Drying machine 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 of the Rota cone drying equipment also assures the maximum collection of solvents is achieved, protecting operators and the environment.
The Rota Cone Vacuum Drying equipment is ideal for avoiding oxidation of chemicals 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 dryers with contact parts to be built in Carbon steel, SS304, SS316/316L, Titanium, Duplex stainless steel, etc. Standard of internal and external finish can be adapted to the customer’s needs.
A double conical vacuum dryer can have a variety of feeding & discharging methods that match the demands of the filling & production line.
