Detailed description

Boiling dryer closed cycle principle:
        closed-loop fluid bed dryer is a closed loop system. Initially, start the fan, open the valve 1, close the valve 2, the input of inert gas (usually nitrogen), the system will be replaced with the original air when the oxygen content in the system reaches a predetermined index, close the valve 1, open the valve 2 .. Since then, the system with nitrogen as the heat transfer and mass media, the completion of the purpose of drying wet materials. After the organic solvent contained in the wet material gasification, together with the nitrogen into the condenser, the solvent condenses into liquid into the tank, due to the low boiling point can not be liquefied nitrogen, driven at the fan into the next cycle. Closed cycle boiling dryer system drying apparatus according to claim status and material selection cylindrical boiling dryer (also known as efficient boiling), can also be a box-type boiling dryer can also be vibration fluidized bed dryer, or even air dryer, because these dryers are fluidized drying, so the higher the rate of drying, short drying time of materials.

Closed cycle boiling dryer features:
1, the system closed, almost no oxygen (controlled content). As described above, the closed loop system boiling dryer is in the closed state of the job, neither (not allowed) leaked out, there is no (not allowed) inward leakage. To this end, we must do all parts of the system, whether pipe interface, or the cabinet air inlet and outlet; either in the positive zone, or negative pressure zone; both static and dynamic parts or components, must be strictly sealed. Oxygen content within the system does not exceed process requirements to ensure that the flame-proof security, but also the fear of oxygen materials to provide a reliable guarantee. 
2, zero emissions. If the system is a continuous operation, then the basic no emissions
3, solvent recovery. Systems such as continuous operations, vehicle recovery rate is very high (up to 98%), its economic significance is self-evident. 
4, the high degree of automation. I set up the system of automatic control of temperature, oxygen content, the three parameters of the system pressure gauge and warning device, PLC control, easy to operate, safe and reliable. 
Closed cycle boiling dryer range of applications:
the pharmaceutical industry granulation: tablet granule, granules, capsules, granules. 
Food industry Granulation: cocoa, coffee, milk powder, granule juice, spices and the like. 
Other industries granulation: pesticides, feed, fertilizer, pigment, dyestuff and so on. 
                              Powdered or granular drying wet materials. 
Coating: granule, pill protection layer, color preparation, sustained-release, film, and other enteric coating. 
Closed cycle boiling dryer equipment Technical note:
        closed loop fluid bed dryer is a drying machine, heaters, condensers, bag filter, blower and silo components. Entire drying process is in a confined environment under nitrogen and dried, the material carried in a closed environment, with no dust, high security features. 
        Closed cycle boiling dryer before use, the use of nitrogen to displace air in the system, so that the oxygen content within the system to achieve a safe concentration of the solvent. Wet material in a sealed container, the feed inlet device into the drying machine. Blower into the nitrogen after filtering, heated by the heater to the desired temperature of the drying process, the fluidized bed into the charging port by the difference added materials for heat and mass transfer (dried), dried to the desired material after the addition was complete final humidity. Closed cycle boiling dryer during the drying process, hot and humid with a few gas soot filter through all of the above 2um soot filter in gas-solid separation. Solid dust in the dust collection, gas into the multi-stage condenser (fin condenser pressure drop, good condensation effect), the condensed solvent gas heat inside. The condensed solvent is collected after collecting tank for storage (zero emissions into the air, it can be recycled). Dried nitrogen condensed dehumidified and then the heater blower into recycling. Material Material closed circulation after boiling dryer for completion by the flap mechanism hot air distribution plate is placed under the barrel, the vacuum pump or air delivery system input to the sealed container storage dispensing (access to materials are in a closed environment within the operating workshop no dust). 
Closed cycle boiling dryer Benefit Description:
1, the closed cycle dryer after boiling solvent containing moisture enters the condenser heat, the gas condensed solvent (solvent recovery of 95% or more), you can either be recycled solvent dehumidification drying gas condensate. The recovered solvent can be recycled again, it can save costs, but will not cause environmental pollution emissions. Gas heat and moisture through condensation and dampness, absolute humidity low gas inside (compared with the normal boiling drying), drying capacity becomes stronger, better adapted to the humidity of the environmental impact of hygroscopic materials. 
2, closed cycle boiling dryer is fully enclosed structure, internal equipment filled with an inert gas (such as nitrogen), when dried anaerobic material or material containing flammable solvent properties of the gas in the absence of oxygen, can not be burned or oxidized , can effectively prevent fire or explosion occurred in the production of equipment, and therefore safer than ordinary equipment. 
3, closed-cycle operation of the internal fluid bed dryer needed to wind down, only a slight positive pressure, the device is equipped with a fan power is reduced, because hot air is blown upward from the lower hopper screen when positive, penetrating wind strong, although the material boiling height is not high, but the hot air in contact with the material more fully, faster drying rate. The device reduces fan power after noise device becomes smaller, but also saves energy. 
4, closed loop fluid bed dryer with a flap mechanism, realized under the conditions of a fully enclosed material, greatly reducing the dust completely within the labor intensity and operating workshop, good workshop environment, a high degree of automation. 
5, closed cycle boiling dryer host pulse dust removal system, dust removal efficiency, the dust does not bond with the cartridge, easy to assemble and clean. 
Closed cycle boiling dryer Features and Benefits:
Safety
        closed circulating fluid bed dryer is fully enclosed structure, internal equipment filled with nitrogen, when dried anaerobic material or material containing flammable solvent properties of the gas in the absence of oxygen, Unable to combustion or oxidation, can effectively prevent the fire or explosion occurred in the production of equipment, and therefore safer than ordinary equipment. 
Efficient
        closed cycle boiling dryer host pulse bag dust removal system, dust removal efficiency, the dust does not bond with the cartridge, easy to assemble and clean. And use the machine cleaning technology (patented technology) in a closed loop after boiling dryer equipment to complete the whole offensive, its dust thoroughly after using this technology equipment bag cleaning frequency from the original 1-2 Tianyi extended wash Tianyi 12-15 to wash. Closed cycle in the lower boiling dryer host departmental rotation, may be evacuated to a vacuum discharge material storage device, reducing the strength of workers to operate and improve efficiency. 
Environmental protection
        through the closed cycle dryer after boiling solvent containing moisture enters the condenser heat, the gas condensed solvent (solvent recovery was more than 95%), and can either be recycled solvent condensation dehumidification drying gas. The recovered solvent can be recycled again, it can save costs, but will not cause environmental pollution emissions. 
Saving
        closed-cycle operation of the internal fluid bed dryer needed to wind down, only a slight positive pressure, the device is equipped with a fan power is reduced, because hot air is blown upward from the lower hopper screen when the positive pressure, and strong penetration of wind Although the material boiling height is not high, but the hot air in contact with the material more fully, faster drying rate. The device reduces fan power after noise device becomes smaller, but also saves energy. 
A broad spectrum of
        closed cycle boiling dry heat and moisture inside the dryer gas dehumidified through condensation, the gas within the low absolute humidity, drying capacity becomes stronger, more responsive and sensitive to the humidity of hygroscopic materials. For smaller particles of material: due to wind down, escape the material is small, it will be fully recovered in secondary dust. 
Closed cycle boiling dryer during the drying process for the fluidized material and hot air gas-solid contact area, and dry strength, high efficiency, and with increased efficiency in the use of equipment, equipment fan flow improvement, equipment you can still guarantee; not like static vacuum drying system, with the increase of the equipment, its drying efficiency getting lower and lower. Closed cycle drying process boiling dryer fluidized material to avoid the vacuum drying system of local materials in direct contact with the heated surface material and the material deterioration caused by overheating, and other adverse conditions.
