With the guidance and participation of users, our company has successfully developed a fully open rake type stirring vacuum dryer based on the basic foreign rake type vacuum dryer, after repeated research and demonstration. Once this product was launched, it received unanimous praise from both new and old users due to its characteristics of easy cleaning, solvent recovery, simple operation, high efficiency and energy saving, and improved product quality!

Scope of application for full door (cantilever) vacuum rake dryer：

1. Crystalline products in granular form can denature even at low temperatures. Thermally sensitive products come from toxic and/or easily oxidizable products in filter presses or centrifuges
Due to the following characteristics of this dryer, the drying time is greatly shortened:
Continuous mixing and stirring of the product with excellent heat transfer performance for both heating and cooling of the powder. Online sampling does not require breaking the vacuum or shutting down the machine

The important advantages of the full door sterile vacuum (rake type) dryer are:

Adopting a quick opening flat head for easy cleaning and verification, all surfaces in contact with the material are heated, such as the tank body, rear head, front head, mixer, and dust collector, which can provide efficient heat exchange efficiency. Double end wet, dry, or non-contact mechanical seals are suitable for the production of sterile products. The CIP and SIP systems comply with cGMP and FDA regulations

1. Short time: The internal cavity of this machine is equipped with heating devices for the spindle, rake teeth, and front door, with a large and uniform heating area; The material undergoes both circumferential and axial flipping within the inner cavity, with the heated surface constantly updated and dynamically dried without dead corners; Due to the use of vacuum drying, the drying temperature has been reduced, thereby shortening the drying timeAnd the dried material does not change color, which not only improves production capacity but also enhances product quality.

2. Low energy consumption: The unit directly heats materials through heat conduction, and its heat source comes into direct contact with the materials, improving efficiencyBy improving heating efficiency and adopting vacuum drying method, the drying temperature is reduced. In addition, an effective insulation layer prevents heat loss, shortening the drying time and saving energy.

3. The solvent recovery effect is significant: the enterprise reduces costs, increases benefits, and meets environmental emissions requirementsRequire and ensure safe production.

4. Hot dust collector: During the operation of traditional dryers, it is often caused by blockage of the collector or filter materialThe filter material is often replaced due to compaction. Our company's designed hot state collector can produce continuously for more than 30 days without the need to replace the filter material. In addition, we have designed a vacuum blowback device to allow the material to fall directly into the dryer chamber without pollutionDyeing.

5. Stability of the equipment: After 5 years of use, this unit has been running very stably. Long serving users have been using it for 5 years and it is still running stably. Due to its reasonable structure, there is almost no maintenance required. Unique spindle sealing mechanism ensures no leakage after one year of use, and long-term users only replace the sealing element after four and a half yearsItem.

6. Flexibility of operation: The unit operates flexibly, and a female comrade can easily open and close the door. Equipped with automatic feeding and discharging devices, as long as the discharge button is lightly pressed, the material will be automatically discharged from the inner cavity and then transported to the material bin for packaging by the conveying device, achieving fully automatic closed operation, reducing personnel configuration, and improving work efficiencyWork efficiencyRate, no secondary pollution.

7. Adjustable rake teeth are installed inside the cavity to achieve all-round wall scraping without dead corners, ensuring that the residual amount of materials meets the standard.

8. The unit adopts an explosion-proof variable frequency control system, which is easy to operate and ensures the safety of production
