Single Shaft Vacuum Harrow Hollow Paddle Dryer for Chemical Industry

single shaft vacuum harrow hollow paddle dryer for chemical industry

Description :

Vacuum drying is to put the dry material heated drying under vacuum condition. It is the use of vacuum pump for suction wet make work indoor vacuum state, accelerates the drying speed. Can get higher under the low temperature drying, Heat use fully. Can dry or dry heat-sensitive materials at low temperature, especially suitable for dry material containing solvents and solvent to be recovered. The machine adopts interlayer heating mode, heat transfer surface is big, high thermal efficiency, set up the stirring, within the cylinder form a continuous loop of material state, further improving the heating uniformity of the material. Applicable to the pharmaceutical, chemical, food, electronics, medicine and other industries dry heat-sensitive materials.

 Application:
Vacuum rake dryer suitable for the high slurry, paste, below 100 mesh material, NiTou shape material, soda ash, detergent, alkali starch, dyes, pigments, dry clay ash, cement and other materials.Medicine, food, chemical and other industries use vacuum rake dryer to dry the following materials: 1, paste, pulpiness, powder materials; 2, drying heat-sensitive materials at low temperature ; 3, easy oxidation, explosive, strong stimulation, virulent material; 4, required materials recycling organic solvent.

CMC, dye intermediates, salicylic acid, rubber additives, maltodextrin, pharmaceutical intermediates, anthraquinone, allyl sulfonate, wellknown blue, reduction of carboxymethyl starch, phthalein olive R, card will polymers, 2 amino anthraquinone, etc

Single Shaft Vacuum Harrow Hollow Paddle Dryer for Chemical Industry
 

WORKING PRINCIPLE

ZPG Vacuum Harrow Dryer is an innovation horizontal batch-type vacuum dryer improved on the basic of introduced technology of harrow dryer.

The moister of wet material will be evaporated by heat transmission. The stirrer with blade will remove material on hot surface and move in the container to form cycle flow .The evaporated moisture will be pumped by vacuum pump.

 

FEATURES

1. This dryer adapted the interlayer heating technology. The heat conducting area is large and the heat efficiency is high.

2. This dryer is equipped with stirring device; it keeps the raw material in a continuous circling status inside of the cylinder so the heating uniformity is improved greatly.

3. With the stirring functions, the dryer can easily dry the pulpiness, paste-like mixture or powder materials.

 

APPLICATION

This dryer is widely used in pharmaceutical industry, foodstuff industry, chemical industry and etc. Especially suitable for the following materials:

1. Pulpiness, paste-like mixture or powder materials.

2. Thermal sensitive material which required to be dried at lower temperature.

3. Materials that are easy to oxidize or explode and the material that have strong irritative or toxic.

4. Materials that required recovering solvent.

Notes:

The evaporated amount of water is related to the characteristics of raw materials and the temperature of inlet air and outlet air. When the temperature of the outlet air is 90°C, the water evaporated curve is listed in above table (for reference only). If the product have been improved or updated by new technology, the related parameters will be change accordingly!
