One Types of single cone spiral belt vacuum dryers

IIOverview of Single Cone Spiral Belt Vacuum Drying Machine

Cone spiral belt vacuum dryer is a type of drying and crushing machine that combines drying and crushing,An efficient and multifunctional fully enclosed vertical vacuum drying equipment that integrates vacuum distillation and powder mixing. Its drying efficiency is of the same specification“Double cone rotary vacuum dryer”1-2Twice.

IIIPerformance characteristics of single cone spiral belt vacuum dryer

Strong applicability: Combined with our company's special drying process, it can adapt to high viscosity,Poor thermal penetration, easy to roll, and prone to clumping and drying of materials.

Large production capacity: With a large amount of material, it can reach the effective volume of the container80%.

High drying efficiency: The effective heat transfer area is large, which is the area inside the container1.4The material rises in a spiral shape inside the container and then descends in a vortex shape along the main axis, uniformly and effectively dispersing in motion When heated, the high vacuum at the machine head and the high-speed airflow at the same temperature and direction at the machine bottom combine to efficiently remove the solvent of the material. The dual channel vacuum tube mouth prevents vacuum blockage, reduces resistance, and increases the pumping rate.

High mixing accuracy: It can achieve high mixing accuracy, even when mixing materials with different densities and particle shapes in the same batch of products, it can still be achieved in a conical mixer The required mixing accuracy can be achieved by adding a small amount of material to a large batch of materials under harsh process conditions, and can also be mixed in a conical spiral belt vacuum dryer produced by force drying.

Low shear force spiral belt stirring: Using a low shear force spiral belt stirring blade, the material is gently mixed at low speed and low energy consumption, resulting in low mixing strength and mixing time. The company independently develops a patented single cone spiral belt agitator blade.

Non destructive material behavior: Materials with high thermal sensitivity and behavior requirements will not be damaged. The drying process is fully sealed and filled with nitrogen to protect production, with no cross contamination, high cleanliness, and safety High 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.

Meet the production requirements of sterile raw materials: online optionalSIPandCIPAnd online sterile sampling, sealed with the upper and lower processes, the entire production process is sealed to meet the new versionGMPProduction requirements.

FiveAdvantages of Single Cone Spiral Belt Vacuum Drying Machine Technology

Compared to old drying equipment, the single cone dryer operates under fully enclosed conditions, with material lifting and self scattering.

1.During the material drying process, the trap equipped with a blowback system can assist in ensuring the smooth flow of the vacuum pipeline and achieving rapid drying. Independently designed by the company, this device has a simple structure and is easy to replace. Different filters can be selected according to different powder particle sizes.

2.The function of nitrogen is achieved by vacuuming with a vacuum pump0.99Pa Shi, the dryer has also reached0.99Pa, the water and solvent extracted from the dryer can no longer be extracted from the capture port. They have reached equilibrium, and it is necessary to break this equilibrium. Our company's nitrogen replenishment system can inject nitrogen from the bottom of the material to replenish nitrogen without affecting the vacuum. The water and solvent suspended in the tank are sent to the vacuum trap and extracted from the vacuum tube. Nitrogen can protect materials from oxidation and provide stable protection during the heating and drying process. Nitrogen can play a role in flame and explosion prevention. When nitrogen gas at the same temperature enters the dryer, condensation will not occur, and at the same time, the bottom5-8mmPushing up the materials eliminates the phenomenon of dead corners and material accumulation.

3.The single cone temperature measurement system produced by our company has a qualitative difference from the temperature measurement systems produced by other companies. Our temperature measurement probe is located between the material of the shaft and the jacket, and the temperature in between is accurate. However, the temperature inserted from outside the jacket is inaccurate because the jacket is heating up.

4.The cleaning of the single cone dryer poses certain difficulties, especially on the back of the blade. Our company has specially designed a cleaning ball to clean the back of the blade.

5.According to the requirements of the pharmacopoeia, our company has developed a receiving bin to protect the environment and workers' health. The receiving bin plays a role in fully enclosed discharge, and the dried material will not have dust flying when discharged from the single cone, which protects the environment and workers' health.

6.Large caliber ball section discharge valve, real ball section valve, powder, liquid and gas seals, eccentric shaft structure, frictionless and unobstructed sealing surface, fully open in the diameter direction. Hygiene type andGMPStandardized design, no dead corners, no residual materials, easy to clean. The standard material for the structure isSUS316L，SUS304Stainless steel, with no cast parts in the structure, and no porosity or shrinkage defects. Sealed bearing chamber, standard surface treatment, interiorRa0.4um, ExternalRa0.8umThe design can be used for full vacuum and0.25MpaPressure, designed to allow nitrogen gas to pass through, beneficial for vacuum drying and eliminating stirring dead corners. The design can be filled with cleaning solution to clean the inside of the valve body.

7.The vacuum sampling valve is directly connected to the spiral heating cone dryer without any dead corners, avoiding contamination of the sampling sample. The working pressure of the sampling valve0.8Mpa,Full vacuum, operating temperature150 degrees.

8. Mechanical seal rotary joint, independently improved by the company, with a rotary joint with internal mechanical seal to prevent leakage.
