Calcium Formate Disc Dryer LPG Continuous Electric Heating

Calcium formate introduction:

Calcium formate is an organic substance with the molecular formula C2H2O4Ca. It is used as a feed additive for all kinds of animals. It has acidifying, mildew-proof and antibacterial effects. It is also used in industry for concrete, mortar additives, leather tanning or as a preservative.

Working Principle:
Wet materials are continuously added from the feeder to the first drying plate on the upper part of the dryer. The rake arm with rake leaves rotates to make the rake arm rotate and the rake leaves continuously turn over the materials. The materials flow over the surface of the drying plate along the exponential spiral line. The materials on the small drying plate are transferred to the outer edge and fall from the outer edge to the outer edge of the large drying plate below. The materials on the large drying plate move inward and fall from the middle drop port to the next small drying plate. The large and small drying plates are arranged alternately up and down, so that the materials can flow continuously through the entire dryer. The heating medium is introduced into the hollow drying plate. The heating medium is in the form of saturated steam, hot water and heat transfer oil. The heating medium enters from one end of the drying plate and is discharged from the other end. The dried materials fall from the last drying plate to the bottom layer of the shell and are transferred to the discharge port by rake leaves for discharge. The moisture escapes from the material and is discharged from the moisture discharge port on the top cover. The moisture of the vacuum type plate dryer is discharged from the vacuum pump port on the top cover. The dry materials discharged from the bottom layer can be directly packaged. By adding auxiliary equipment such as fin heaters, solvent recovery condensers, bag dust collectors, dry material remixing mechanisms, induced draft fans, etc., its drying production capacity can be improved, pastes and heat-sensitive materials can be dried, solvents can be easily recovered, and thermal decomposition and reaction operations can be performed.

Performance characteristics:
(i) Easy to adjust and adaptable:
◎ By adjusting the material layer thickness, spindle speed, number of rake arms, rake blade type and size, the drying process can reach the ideal state.
◎ Each layer of the drying plate can be heated or cooled by the hot medium or cold medium alone, and the material temperature can be accurately and easily controlled.
◎ The residence time of the material can be adjusted.
◎ The flow direction of the material is single, there is no back-mixing phenomenon, the drying is uniform, the quality is stable, and no re-mixing is required.
(ii) Simple and easy operation:
◎ The start-up and shutdown operations of the dryer are very simple.
◎ After stopping the feeding, the conveying material dirt rake blade can quickly empty the material in the dryer.
◎ Through the special large inspection door mirror, the equipment can be carefully cleaned and observed.
(iii) Low energy consumption:
◎ The material layer is very thin, the spindle speed is low, the material conveying system requires small power and low power consumption.
◎ Drying is carried out by heat conduction, with high thermal efficiency and low energy consumption.
(IV) Good operating environment, solvent can be recovered, and dust emission meets the requirements
◎ Normal pressure type: Due to the low air flow velocity in the equipment and the high-up and low-down distribution of humidity in the equipment, it is difficult for dust to float to the top of the equipment, so the tail gas discharged from the top dehumidification port contains almost no dust.
◎ Closed type: Equipped with a solvent recovery device, it can easily recover organic solvents in the wet gas. The solvent recovery device is simple and has a high recovery rate. For flammable, explosive, toxic and easily oxidized materials, nitrogen can be used as a wet gas for closed-loop circulation to make it safe to operate. It is especially suitable for drying flammable, explosive and toxic materials.
◎ Vacuum type: A disc dryer operated under vacuum, especially suitable for drying heat-sensitive materials.

(V) Easy installation and small footprint:
◎ The dryer is shipped as a whole and transported as a whole. It only needs to be hoisted into place, and installation and positioning are very easy.
◎ Due to the layered arrangement of the drying plate and vertical installation, even if the drying area is large, the footprint is very small.
