Drying System, Brand Name : KRD

Krd bulk drying system is built on the prominent components and advanced technologies, with reasonable layout and reliable process, which consists of krd high performance bulk mixer, a heater (via electricity, steam or combustion), a cooler (via condensation and air), a heating exchanger, a centrifugal fan and a 2-phase filtration system. The primary filter will clean the medium continuously; and the secondary filter will collect fine particles; and in the same time heat pumps will increase the total thermal efficiency. The krd bulk drying system will dry the materials in a gentle condition to achieve the optimal operation cost.
heated air is blown into the mixer and mixed with material. During this heat exchange, the moisture will be evaporated from the material. Moist air will pass through the filter and be drafted into the cooler via the fan for condensation and then be reheated. When drying very moist materials, dry materials will be added to ensure that the fluidization and the drying rate.
both closed and open bulk drying systems are available. The system usually is equipped with a series of dryers, and materials are processed batch by batch. For some special applications, the dryer can operate continuously where material is separated from the exhaust air through a cyclone or a filter system.
features of homogeneous drying:
 no partial overheating,
 no partial over drying,
 gentle and even drying,
drying in the low temperature condition, optimal correlation between product temperature and exhaust temperature, the integrated mixing technology, which always ensures homogeneous drying for each batch.
drying capacity:
 high thermal transmission capacity,
can operate in the upper-limited temperature, which the materials can bear, to increase the drying efficiency, continuous and controlled air supply, fresh air maintained, optional heating pumps to increase total thermal efficiency, batch or continuous drying, close to absolute dryness.
inert gas drying:
 for special applications,
krd supplies the bulk drying system with inert gas as a drying medium.
advantages:
 prevent materials from being oxidized,
can dry solvent based material, reduce the possibility of explosion, closed loop reduces inert gas consumption
closed loop:
 no odor leaked to the environment
constant drying conditions, no gas or dust leaked, condensation of water vapor, energy recycle.
Inert gas drying as an option, open system as an option
control system:
 customized control system,
monitored temperature and mixture to ensure stable drying, easily set stop-parameters for batch process, spillage and over drying avoided automatically, no dust leakage during filter cleaning and monitoring, automatic operation
