Main Structure and Performance of Double Cone Rotary Vacuum Dryer

Main Structure and Performance:

 

1. The drying chamber has a 60-degree tapered design at both ends, facilitating smooth unloading of finished products in one go.

 

2. The equipment is equipped with a timer. Forward, reverse, and jog buttons ensure the chamber stops correctly at the desired position, guaranteeing reliable unloading.

 

3. PLC control and data printing can be provided upon request; real-time printing of drying time, vacuum level, and temperature changes enhances traceability during production and stabilizes product quality.

 

4. This unit can be equipped with a low-temperature condensation system and a micro-dust separation system, which can recover evaporated solvents and optimize the working environment of the vacuum pump during drying.

 

5. The inner and outer layers of the cylinder are all made of stainless steel, avoiding potential difference corrosion at the weld between the carbon steel heating layer and the stainless steel, which could lead to weld perforation and unnecessary maintenance.

6. The frame is integrally welded from carbon steel plate and heavy-duty channel steel; the entire frame undergoes vibration aging treatment. The frame mounting surface is integrally milled using a large floor-type boring machine to ensure the verticality and parallelism of the shaft seats at both ends of the cylinder. The outer cover is made of mirror-finished stainless steel plate, preventing overall deformation.

 

7. Both ends of the double cone spindle are integrally formed and then precision-machined on a boring machine; ensuring the concentricity of the two shafts is between 0.10mm and 0.16mm, guaranteeing stable operation of the equipment and increasing the service life of other mounting components at both ends of the bearings.

 

8. Both the vacuum and heating ends use mechanical seals.

 

9. The vacuum filter head is made of imported 316L sintered stainless steel mesh, ensuring stable and reliable filtration quality.

 

10. Depending on the characteristics of the material, one to two adjustable-speed crushing devices can be installed in the cone section of the equipment to prevent material agglomeration and balling, ensuring uniform particle size and heating. This reduces drying time, facilitates control of drying quality, and also functions as a crusher and Granulator, reducing material processing steps.

 

11. Depending on the material requirements, a real-time inert gas injection device can be added to stabilize the molecular structure of the material and accelerate the drying time.

 

12. The machine employs a high-speed electric motor and a worm gear reducer. The transmission belt uses a V-belt. Under the transmission of the motor, the reducer gears drive the main shaft gear of the drying cylinder. The drying cylinder rotates on a horizontal axis. The overall transmission structure is simple, robust, and operates smoothly and reliably.

 

13. The rotating supports at both ends of the main shaft use heavy-duty bearings. The transmission uses high-module high-carbon steel gears with high-frequency quenching for durability.

 

14. The end caps of the drying chamber are equipped with an automatic retraction and knocking device to prevent material from remaining inside the caps and ensure uniform heating of all materials.

 

15. The equipment is equipped with "CIP/SIP" devices to meet "GMP" production requirements.
