The cellulose derivation system by the natural high polymer cellulose after chemistry modifications and so on the etherification or esterification as well as passes through the versatility high polymer fine chemical industry material again which but the stem grafting makes results in. As soon as the cellulose derivative distributes four types: ¢ÙCellulose ester (nitrocellulose, third acetyl cellulose, viscose cellulose). ¢ÚCellulose ether (ion carboxymethyl cellulose and non-ionic methylcellulose, ethyl cellulose, ethylol cellulose, hydroxy propyl methylcellulose). ¢ÛCellulose semi-permeable membrane (for example cellulose triacetate and two acetyl cellulose mix membrane). ¢ÜCellulose derivative stem grafting modification (for example coherent cellulose and styrene stem grafting modification, styrene and propylene nitrile mixture and viscose cellulose graft polymer).

The main purpose of product
Cigarette filter tip, vinegar fibrous plastic moulding material, film, coating, polyreaction, building materials, oil field, spinning and weaving, food, medicine, electronic component and so on. The similar type also widely applies in the wood pulp, material and so on purification cotton and kapok dry. 

(1): The turnover material time is advantageous for the adjustment and the control, guarantees the material moisture content and the uniformity.
(2): The different sector entered rheumatism to adjust, reduced the energy consumption and improves the quality of the product.
(3): The equipment flow has regards the mirror and the gate, is advantageous for the observation and the cleaning up (pneumatic drier shoe and tornado easy product material, cannot clean up!).
(4): Because uses the low pressure air blower, the use amount of wind is big, the output easy to guarantee, the dust displacement small ). 
(5): Under the vacuum state for drying, the safety coefficient is high. 
(6): Passes in and out continuously the material, reduces the area and the pollution.

Passes through many year practices in view of cellulose dry craft this company, the optimized improvement part production equipment: The seriation production practice experience supplies the reference:
For example: The CMC, HPMC, HEC, MC and son on of Cellulose of mature drying craft. 
(1 ): Two level of pneumatic driers.
(2 ): Two level of vibration fluid bed dryer.
(3 ): The level air current and the fluid bed dry combination for drying.
¡ñThe modified cellulose dry mature craft, uses the continual vacuum disc type to be dry. 
¡ñThe HeBei partial users use the vacuum rake type dryly (the main characteristic: A little batch raid of production, solvent recovery). 
¡ñHas a part of cellulose to use the single air current dry or the flash vaporization dry, the conveyor-type drier, the drying oven ebullition dry and so on.
