Working principle of amino acid tray continuous dryer
Wet material is continuously added from the feeder to the first drying tray on the upper part of the dryer. The harrow arm with harrow blades makes a rotating motion so that the harrow blades continuously turn over the material.The material flows along the surface of the drying pan along an exponential spiral. The material on the small drying pan is transferred to the outer edge and falls to the outer edge of the large drying pan below. On the large drying pan, the material moves inward and falls from the middle. The material inlet falls into the next small drying pan. Large and small drying trays are arranged alternately up and down so that the material can flow continuously through the entire dryer. Heating medium is introduced into the hollow drying plate. The heating medium takes the form of saturated steam, hot water, heat transfer oil and high-temperature molten salt. The heating medium enters from one end of the drying plate and is led out from the other end. The dried material falls from the last layer of drying pan to the collecting pan, and is finally transferred to the discharge port by the rake blades for discharge. Wet content overflows from the material and is discharged through the moisture discharge port arranged on the top cover. The wet content of the vacuum type tray dryer is extracted through the vacuum port arranged on the top cover. Dry material discharged from the bottom layer can be packaged directly. By adding auxiliary machines such as finned heaters, solvent recovery condensers, pre-dryers, and induced draft fans, its drying production capacity can be improved. By drying paste and heat-sensitive materials, solvents can be easily recovered, and heating can be carried out., cooling, calcination, sublimation, pyrolysis and reaction operations.

Usage characteristics
1) Easy to control. The drying process can be optimized by adjusting the thickness of the material layer, the speed of the spindle, the number of harrow arms, the type and size of harrow blades.
Each layer of drying pan can be separately introduced with cold and hot media to cool or heat the material, accurately and easily control the material temperature. Accurately adjust the retention time of materials. The material flow direction is single, there is no back-mixing phenomenon, and it is dried evenly without mixing.
2) Easy to operate. Driving and parking of the dryer is very simple.
After the feeding is stopped, the raking blades that convey the material can quickly empty the material in the dryer. Through the special large-scale inspection door mirror, the inside of the equipment can be carefully cleaned and observed.
3) Low energy consumption. The material layer is very thin, the spindle speed is low, the material conveying system requires less power and less power consumption.
Drying is carried out with conductive heat, with high thermal efficiency and low energy consumption.
4) Environmentally friendly and atmospheric pressure type: The air flow speed in the equipment is low, and the humidity in the equipment is high and low. It is difficult for dust to float to the top of the equipment, so the exhaust gas discharged from the top moisture outlet contains almost no dust.
Closed type: Equipped with a solvent recovery device, it can easily recover organic solvents in hygroscopic gas. The solvent recovery device is simple and the recovery rate is high. For flammable, explosive, toxic and easily oxidized materials, protective gas can be used as a moisture-carrying gas for closed-circuit circulation to make it safe to operate. Especially suitable for flammable, explosive and toxic materials drying.
Vacuum type: Tray dryer operated under vacuum, especially for drying heat-sensitive materials.
5) Easy to install The dryer is shipped as a whole, and the overall transportation is only necessary to lift it in place, and the installation and positioning are very easy.
Due to the layered layout of the drying plate and vertical installation, even if the drying area is large, the floor area is also small.
