The ZPG scraper vacuum dryer is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and the scraper agitator continuously clears materials from the heated surface. The materials are pushed around inside the container to form a circulating flow. After the moisture evaporates, it is extracted by the vacuum pump. This machine utilizes a large area of jacket heating, with a large heat transfer surface and high thermal efficiency. The mixing function ensures a continuous circulating state of materials inside the drum, further enhancing the uniformity of material heating, thus facilitating smooth drying operations.
Operating Principle
This unit is a novel horizontal intermittent vacuum drying equipment. Wet material is evaporated through conduction, with a scraper agitator continuously removing material from the hot surface. It promotes a recirculating flow within the container. Once the moisture evaporates, it is extracted by the vacuum pump.
Performance Features
This unit utilizes a large-area sandwich heating method, featuring a large heat transfer surface and high thermal efficiency.
The machine is set for mixing, ensuring a continuous circulation of materials inside the drum, which further enhances the uniformity of material heating.
The machine is set up for mixing, allowing for smooth drying of paste-like, cream-like, and paste materials.
Suitable materials
Materials drying for industries such as pharmaceuticals, food, and chemicals:
Suitable for paste, paste-like, and powdered materials.
Required for low-temperature drying of thermosensitive materials.
Oxidizing, explosive, strongly irritating, highly toxic materials.
Material requiring recycling of organic solvents.
Technical Specifications
Note: The amount of moisture evaporation is related to the characteristics of the material and the hot inlet and outlet temperatures. When the outlet temperature is 90oC, the moisture evaporation curve can be seen in the above figure (for selection reference). Please note that with the continuous update of the product, changes in relevant parameters will not be pre-notified.
