SS304, SS316 Manufactured Vertical Pressure Nauta Conical Dryer

Nauta Cone Dryer is an advanced equipment that integrates various functions such as drying, mixing and cooling. Its unique cone design allows the material to fully contact the heating surface during the drying process, improving the heat transfer efficiency, while reducing the residence time of the material in the equipment to avoid overheating or burning. In addition, the equipment is equipped with an advanced vacuum system, which can achieve efficient drying at low temperatures, effectively protecting the nutrients and active substances of the material.

Products Description

Nauta conical dryer is an efficient, fully sealed, multifunctional vertical vacuum drying equipment integrating drying and mixing, using the spiral belt to rotate and lift materials, meanwhile, simultaneously filling the conical jacket and the hollow spiral belt with the heat transfer medium (such as hot water, heat transfer oil, steam, etc.), so that the heated materials can be lifted from all around, and fall in the middle, then quickly and continuously turn over. The water vapor is taken away in time through vacuum pumping in the cylinder, so that materials can be dried and mixed in a short time.

Structural Features and Functions

Materials of the reaction kettle are heated by jacket.

Heated internally by the jacket and spiral belt, the heating surface of the equipment has been enlarged by 40%.

The single spiral belt agitator used in the equipment is a patented product of our company, which can achieve cycle-mixture from bottom to up with good performance of efficient forced heat transfer. When the material loading rate is 40% ~ *, the heating utilization of * can be realized. It is applicable for mixing and drying fine materials.

Completely sealed system, without pollution of foreign matter, high purity, especially applicable for mixing and drying of pharmaceutical intermediates, APIs and sterile APIs.

The gap between the single spiral belt agitator and the container wall is so small that can effectively prevent materials from adhering to the surface of the container wall.

The conical cylinder structure with small angle is adopted to make discharge fast and clean, without accumulation.

In the process of material drying, the dust raised is adsorbed on the vacuum trap, blocking the vacuum channel, and this leads to the extension of drying time. The lower the temperature is during the drying process, the shorter time it takes, and the less the impact on the material quality is. In view of all above, the single cone dryer developed by our company is equipped with a blowback device on the vacuum trap, which can keep the vacuum channel unblocked to shorten the drying time and improve the drying outcome.

The bottom discharge valve is the extraction kind with good performance of reliable sealing and vacuum drying.

The equipment has the advantages of compact structure, smooth operation, good sealing, no lubrication leakage, simple operation, and long service life.

Strong adaptability: it is suitable for drying materials with high viscosity, poor heat penetration and easy to pill and agglomerate

The loading coefficient can be up to 80% of the effective volume

Large heat transfer surface and uniform heating of materials. The gap between the spiral belt and the cone is so small that can effectively prevent materials from adhering to the inner wall

Small shear force: no damage to materials with high thermal sensitivity or high requirement on particle size

Online SIP, CIP and online aseptic sampling are optional 1．

Scope of Application

It is applicable to the concentration, mixing and drying of powder, granular and fiber in chemical, pesticide, dye, pharmaceutical, food, additives, and other industries, as well as materials requiring drying under low temperature (such as biochemical products), and it is more suitable for drying easily oxidized, volatile, heat sensitive, strongly irritating or toxic materials, or those crystals that are not allowed to be destroyed.
