Tray Dryer is an efficient conduction continuous drying equipment. Its unique structure and operating principle determines that it has high thermal efficiency, low consumption, small size, configuration is simple, convenient control, operating environment and good features, widely used in chemical, pharmaceutical, pesticide, food, feed, agricultural by-product processing industry, drying operation. Practice in the industry to use well received. Production pressure is sealed, the three types of disk-type vacuum dryer, where A (carbon), B (uniform access to some materials of stainless steel), C (in the B basis, increased steam pipes, spindles and brackets stainless steel, stainless steel tube and the roof lining). And can provide the kind of matched with auxiliary equipment to meet the users need a variety of materials to dry.
Wet material from the feeder tray dryer continuously added to the top of the first layer of drying the plate, with a target leaves the target arm for rotary movement to the target arm for rotary movement to the target leaf turning continuously copied material. Material along the spiral flow through the drying index plate surface, in a small drying plate material was transferred to the outer edge, and fell below the outer edge of the outer edge of a large drying plate in the plate material to make a big move from the middle years entrance and exit off the plate as a layer of small dried. Size of the drying plate alternating up and down, the material to continuously flow through the entire disc dryer. Blow drying tray into the heating medium through the heating medium in the form of saturated steam, hot water and thermal oil heating medium into one end of the drying plate, derived from the other end. Dried material from the last layer of dried shell fell on the bottom plate, eventually rake leaves transferred to the discharge port. Were in the overflow from the wet material from the roof on in the humidity and discharge port, vacuum-type disc dryer moisture by the vacuum in the top cover on the discharge port. Discharged from the bottom of the dry material can be directly packaged. Through with additional fin heater, solvent recovery condenser, bag filter, back mixing of dry material bodies, Fan and other auxiliaries can increase their production capacity and dry, dry paste, and heat sensitive materials, can be easily recovered solvents, and can carry out thermal decomposition and reaction operations.
(A) of the disc dryer easy to adjust, applicability
1, by adjusting the material thickness, spindle speed, the target arm number, leaf type and size of target to achieve the best drying process.
2, each floor plate Jieke separate drying or cold through the medium into the medium, heating or cooling of the material, material temperature control accurate and easy.
3, the residence time of material can be precisely adjusted.
4, the flow of a single material, no back mixing, uniform drying, stable quality, do not need to mixing.
(B) of the disc dryer is simple, easy
1, dryer drive, parking operation is very simple.
2, stopped feeding, the leaf used to transfer the target scale can quickly emptying the dryer material.
3, by a special large format view door mirrors, can be carried out very carefully on equipment cleaning and observation.
(C) low energy consumption disc dryer
1, very thin material layer, spindle speed is low, material delivery system needs small power, less power consumption.
2, in order to transfer heat to dry, high heat efficiency, low energy consumption.
(D) of the disc dryer operating environment is good, recyclable solvents, dust emissions to meet the requirements
1, pressure-type: As the device is air velocity is low, and equipment distribution within the upper primary low humidity, dust is difficult to float to the top of the device, the top of the humidity and I almost do not emit exhaust containing dust.
2, seal type: equipped with solvent recovery unit, can easily recall the wet gas containing the organic solvent. Solvent recovery unit is simple, high recovery rate for the flammable, explosive, toxic and easily oxidized materials can be used wet gases containing nitrogen as a closed loop, so that safe operation, especially for flammable, explosive, toxic materials drying.
3, vacuum-type: operate in a vacuum tray dryer, especially suitable for drying heat sensitive materials.
(E) ease of installation disc dryer, small size
1, the overall dryer factory, the whole transport, simply hoisting, positioning is very easy to install.
2, result of the dry plate layer-type arrangement, vertical installation, even if the drying area is large, a very small area.
