DetailThe working principle of ：
Wet material from the feeder continuously added to the drier upside the first layer of dry plate, with a target of leaves and target arm for a rotary motion to make target arm for a rotary motion to make target Ye Lianxu flipping copy material. Index of materials along the spiral flow drying plate surface, in the small drying plate on the material being transferred to the outer edge, and in outer fall at the bottom of the large drying plate edge, in the dry plate material to mobile and from the middle blanking small mouth falls below a layer of dry plate. Size dry plate arranged alternately up and down, material flows through the whole dryer continuously. Dry hollow dish into the heating medium, the heating medium forms with saturated steam, hot water and heat conduction oil, heating medium from one end of the dry plate, derived from the other end. Already dry material from the last layer of dry plate fall to the bottom of the shell, was finally rake leaves transferred to the discharging mouth eduction. Wet spilled from the material, is being exhausted from port located in the platoon is wet on the lid, the vacuum type disc dryer moisture is being exhausted from port is located in the vacuum pump on the top. From the bottom of dry materials can be directly to packing. Through with addition of finned heater, solvent recovery condenser, bag filter, dry backmixing mechanism, induced draft fan and other auxiliaries, can improve its production capacity, dry dry paste and heat sensitive material, can be easily recovered solvents, and thermal decomposition and reaction can operation.
Product features ：
(a) easy adjustment, high applicability
1, by adjusting the thickness of material layer, spindle speed, the target number of arm, target leaf type and size to achieve the best in drying process.
2, each layer of dry plate can separate by the medium or cold medium, the heating or cooling, the supplies material temperature control are accurate and easy.
3, material residence time can be precisely adjusted.
4, material flow to a single, without backmixing phenomena, uniform drying, stable quality, no longer need to mix.
(2) simple operation, easy
1, dryer drive, parking operation is very simple.
2, after stop feeding, transfer material scale target leaf can quickly emptying material in the dryer.
3, through the special specification review the sight glass door, the equipment can be carried out within very careful cleaning and observation.
(3) low energy consumption
1, material layer is very thin, the spindle rotational speed is low, the material transfer system need the power of small, less power consumption.
2, by conduction heat drying, high thermal efficiency, low energy consumption.
(4) operating environment is good, recycled solvent, dust emission meets the requirements
1, the atmospheric model: because the device is low air velocity, low humidity distribution is high within and equipment, dust is difficult to float to the top of the device, so the top row of wet mouth almost free of dust in tail gas discharge.
2, seal type: equipped with solvent recovery unit, can be easily recycled carrying wet gas in the organic solvent dhi. Solvent recovery device is simple, high recovery rate, for flammable, explosive, toxic materials and oxidative, available nitrogen as a wet gas in closed cycle, make safety operation, particularly applicable to flammable, explosive, toxic materials dry.
3, vacuum type: operating under a vacuum disc dryer, especially suitable for drying of thermal sensitive material.
(5) easy installation, cover an area of an area small
1, the dryer the whole factory, the overall transport, simply lifting in place, installation location is very easy.
Layer 2, because the dry plate type layout, vertical installation, even drying has a very large area, covers an area of too small.
Range of application：
Calcination cooling dry pyrolysis reaction distillation
(a) the organic chemical industry
(2) of inorganic chemical industry
(3) medicine and food
(4) of feed and fertilizer
