Sodium hydrosulfite chemical plate dryer


  First, the material overview:
  Sodium hydrosulfite is a white sand-like crystal or light yellow powder chemical, melting point of 300 ℃ (decomposition), ignition temperature of 250 ℃, insoluble in ethanol, soluble in sodium hydroxide solution, strong reaction and burn with water.

  

  Second, the principle of Sodium hydrosulfite chemical plate dryer:
  Sodium hydrosulfite chemical plate dryer is a multi-layer fixed plates, rotary rake mixing vertical drying device. The size of the metal plate from top to bottom alternately arranged, each plate is composed of two metal plates, the formation of middle hollow plate. Heating medium low pressure steam. The low pressure steam passes into the plate and passes the heat through the metal wall to the material on the plate in a conductive manner. The dried material enters the dryer from the upper feed inlet and falls on the first layer of the large heating pan and then moves inwardly from the outside of the plate and pushed from the central opening to the next The small plate on the layer, because the small plate on the rake angle outward, so the material in the rake teeth under the rotation was pushed to the outer periphery of the plate. The material is so repeatedly moved downwards during the movement. Evaporation of water exhausted out by the fan. The heat transfer area of the dryer can be ensured by adjusting the number of plates, and the required residence time of the material in the dryer can be achieved by adjusting the speed of the spindle. That is, the speed of movement of the material is adjusted by means of rake teeth to obtain a qualified dry product at the bottom.


  Third, the characteristics of Sodium hydrosulfite chemical plate dryer:
 

(1) Easy to adjust and control, good applicability.

- The drying efficiency can be improved by adjusting the thickness of material layer, rotary speed of main shaft, quantity of harrow arm, shape and size harrow plates.

- Each drying layer can input hot medium or cool medium individually for heating or cooling. The temperature control is accurate and easy to adjust.

- The residence time of materials can be adjusted accurately.

- Single material flowing direction to prevent material return and mixing. The drying process is uniform and the quality stable, no re-mixing is required.

(2) Easy to operate

- Simple operation for turn on and turn off.

- After material feeding is stopped, the remaining material inside of the machine can be easily discharged out by the harrows.

- You can clean and observe inside from the large-scale viewing window.

(3) Low energy consumption

- The material layer is thin and the rotary speed of main shaft is low so it required low power and electricity consumption.  

- The material is dried by conducting heat so it has high heating efficiency.

(4) Good operation environment

- Normal pressure type:

The speed of air flow inside of the machine is low and the humidity is high in upper end and low in bottom end so the dust can’t float to the top which keeps no dust in the exhausted air.

- Closed type:

The machine is equipped with solvent recovery device which can recover organic solvent easily from the wet air. The solvent recovery device has a simple structure and high recovery rate. For the flammable, explosive and poisonous materials, the nitrogen can be used as medium for closed circulation and keeps a safe working condition.

- Vacuum type:

The plate dryer is operating under vacuum condition and it is particularly suitable for drying heat sensitive materials.

(5) Easy installation

- The dryer is delivered in a complete piece so it is quite easy to install and fix at site.

- The disc plates are being arranged by layers and it will be installed vertically so it takes a small occupying area from the workshop.
