WZX series vertical single cone vacuum dryer

product description

The vertical single cone vacuum dryer is an efficient and multifunctional fully enclosed vertical vacuum drying equipment that integrates drying, crushing, vacuum distillation, and powder mixing. Its drying efficiency is 3-5 times that of the same specification "double cone rotary vacuum dryer".

Working principle

The material enters the cone from the upper feeding port, and through the rotation of the screw belt, the material forms an axial flow cycle in the container. The surrounding material flows upward while the central material flows downward, thereby generating strong convection, shear, mixing and diffusion, and continuously circulating, forming a three-dimensional spatial motion in all directions.

The conical jacket, conical head, spiral spindle, and spiral belt are all supplied with thermal energy (hot water, steam, thermal oil), and the material is fully in contact with these components to enter the heat transfer and drying process.

The material is in a high vacuum state, and the water or solvent on the surface of the material reaches saturation and evaporates. It is promptly discharged by a vacuum pump, and the material achieves the drying purpose in a short period of time.

Performance characteristics

1. Strong applicability: Combined with our company's special drying process, it can adapt to the drying of materials with high viscosity, poor thermal penetration, easy rolling and clumping.

2. High production capacity: Large loading capacity, capable of reaching the maximum effective volume of the container.

3. High drying efficiency: The effective heat transfer area is large, which is 1.4 times the container area; The material rises in a spiral shape inside the device, then descends in a vortex shape along the main axis, and is uniformly and effectively heated during dispersed motion; The combination of high vacuum at the machine head and high-speed airflow at the same temperature and direction at the machine bottom efficiently removes the solvent of the material; Double pass through the vacuum tube mouth to prevent vacuum blockage, reduce resistance, and increase pumping rate.

4. No damage to material crystal structure: Materials with high thermal sensitivity and crystal structure requirements will not be damaged.

5. The entire drying process is sealed and filled with nitrogen for production, with no crossing or personnel, high cleanliness, and high safety level.

The gap between the mixer and the container wall is small, which can effectively prevent materials from sticking to the surface of the container wall.

7. Meet the production requirements of sterile raw materials; Optional online SIP and CIP, as well as online sterile sampling. Sealed connection with the upper and lower processes, the entire production process is sealed to meet the new GMP production requirements.

advantage

1. A fully enclosed operating system, especially suitable for materials such as flammable, explosive, toxic or highly toxic food, biological products, drugs, etc. that do not allow contamination or sterile requirements.

2. High loading coefficient, with some materials reaching up to 90%.

3. High heat transfer efficiency - the spiral belt, spiral shaft, jacket, and head are all heated, and the equipment has a large effective heat transfer area.

4. The material undergoes three-dimensional mixing motion in all directions within the cone, resulting in excellent mixing effect. During the mixing process, the material fully contacts the hot surface, shortening the drying time, improving drying efficiency, and reducing energy consumption.

5. The spiral stirrer can effectively prevent material from clumping or sticking to the surface of the device wall.

6. Meet the new GMP production requirements - high-quality equipment surface treatment and elimination of dead corners, materials can be almost completely discharged. The tank and discharge valve can be cleaned online.
