Overview:
The vacuum harrow dryer has the advantages of simple structure, convenient operation, long use period, stable and reliable performance, small steam consumption, strong applicability and good product quality, it is especially suitable for the drying of paste material which is not resistant to high temperature, inflammable and easy to oxidize under temperature regulation.
Principle:
The vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment, the wet material is evaporated by conduction, the scraper agitator continuously cleans the material on the hot surface, and moves in the container to form circulating flow, the water evaporates and is pumped out by a vacuum pump. Vacuum Harrow Dryer, in the chemical industry in the organic semi-finished products and fuel drying operations used more.
The steam jacket used in the vacuum rake drier device is used to indirectly heat the material and exhaust the gas under high vacuum, therefore, it is especially suitable for materials that are not resistant to high temperature, easy to oxidize at high temperature, or easy to produce powder when drying (such as various fuels) , and the material drying operation in which the vapor or solvent removed during the drying process must be recovered. In the vacuum harrow dryer, the moisture content or solvent content of the dried material can reach up to 90% , while the lowest is only 15% . The dried material may be slurry, paste, granular, powdery, or fibrous. The moisture content of these materials after drying generally reaches 0.1% , or even 0.05% .
The dried material is added from the middle of the upper part of the shell, under the agitation of the constantly rotating harrow teeth, when the material contacts with the shell wall, the surface is continuously renewed, and the dried material is indirectly heated by steam, thus making the material moisture gasification, the vaporized moisture is timely pumped by vacuum pump. The machine can adopt the way of heating interlayer and Harrow tooth at the same time. Because the operating vacuum is higher, the water vapor pressure on the surface of the dried material is much larger than the water vapor pressure in the evaporating space of the drier shell, which is beneficial to the discharge of the water inside and on the surface of the dried material, it is advantageous to the movement of the water molecule of the dried material to achieve the drying goal.

Features:
(1) strong adaptability, widely used, because rake-type, vacuum dryer use jacket heating, high vacuum exhaust, so almost all the different properties, different states of materials are suitable for, especially suitable for explosive, easy oxidation, paste material drying.
(2) the product quality is good, because in the drying process, the harrow tooth rotates positively and inversely continuously, is stirred by the dry material evenly, avoids the material overheating, the moisture also easy to escape, the shell obtains the low temperature product. Because of the fine granularity of the product, it can be packed without crushing.
(3) the steam consumption is small, because the vacuum harrow drier often uses steam to pass through the jacket, and uses latent heat to heat the material, the steam consumption per kilogram of finished product is small, generally 1.3-1.8 kg steam.
(4) according to the different characteristics and requirements of the drying materials, the sealing system of the dryer can choose two kinds of packing seal and mechanical seal.
(5) easy to operate, the vacuum harrow dryer is easy to operate, the fixed personnel is few, the labor intensity is low. The environmental sanitation was improved due to the reduction of material loss.
Scope of application:
Mud-like, high paste material under 100 mesh, all kinds of pigments, mud head-like materials, filter and centrifuge filter and soda detergent, alkali starch, dyes, pigments, clay ash, clay, cement and so on.
