ZPGRake dryer--Product Features
This machine adopts a simultaneous heating method of interlayer and internal stirring, with a large heat transfer surface and high thermal efficiency.
The machine is equipped with agitation to create a continuous circulation of materials inside the cylinder, further improving the uniformity of material heating.
This machine is equipped with agitation to facilitate the smooth drying of slurry, paste, and paste like materials.

introduce

It is mainly composed of a shell, a rotating shaft, and rake teeth. Unlike the blade dryer, the rotating shaft and rake teeth of this machine are not used as heating surfaces, but only serve to stir the material and update the surface. The rake dryer is vacuum operated. First, wet materials are added to the dryer, and a heating medium (usually steam or hot water, or thermal oil can also be used) is introduced into the jacket. Then, the vacuum pump is started to reach the specified vacuum degree, and the mixing device is started. The rake teeth rotate forward and backward to continuously push the material towards the middle and both ends during the drying process. At the same time, four stainless steel rods (seamless steel pipes) can also be placed between the rake teeth according to user requirements. It continuously moves up and down during the rotation of the shaft, vibrating the material bonded to the wall and crushing the clumped material. Through these measures, timely updates of the heat transfer surface can be ensured, thereby accelerating the rate of heat and mass transfer.

It is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and a scraper stirrer is used to continuously remove the materials on the hot surface, forming a circulating flow in the container. After the water evaporates, it is pumped out by a vacuum pump.

ZPGRake dryer--Scope of application
Drying of the following materials is carried out in industries such as pharmaceuticals, food, and chemicals:
Suitable for paste like, paste like, and powdery materials. Thermally sensitive materials that require low-temperature drying.
Easily oxidizable, explosive, strongly irritating, and highly toxic materials.
Require the recycling of materials containing organic solvents.
