Description:
The disc continuous dryer is a state-of-the-art conductive continuous drying system. Its innovative structure and operational principles ensure high thermal efficiency, low energy consumption, minimal footprint, straightforward configuration, easy operation and control, and a favorable working environment.
Operational Principle:
Wet materials are continuously introduced from the feeder onto the first layer of the drying plate. A rotating rake arm with rake blades ensures the materials are continually flipped. As materials move along the drying plate surface in an exponential spiral, they transition from the small drying tray to the larger one below, eventually cascading through the dryer in a seamless flow. Each drying plate is alternately arranged to facilitate continuous material movement.
The hollow drying plate is filled with heating mediums such as saturated steam, hot water, thermal oil, or high-temperature molten salt, which enter from one end and exit from the other. Dried materials are collected on an aggregate tray and discharged via the rake blades. Moisture is expelled through dehumidification ports on the top cover, with vacuum disc dryers extracting moisture via the vacuum port. The dried materials are ready for packaging, and auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans can enhance drying efficiency. This system can easily handle drying of pastes, heat-sensitive materials, and can support various operations including solvent recovery, heating, cooling, calcination, sublimation, pyrolysis, and reactions.

Features:
Easy to Regulate
Adjustable material layer thickness, spindle speed, number of rake arms, and rake blade type and size ensure an optimized drying process tailored to your needs.
Each drying tray layer can independently receive hot or cold media, allowing precise control over material temperatures.
Material residence time can be accurately adjusted for optimal results.
The material has a single flow direction, no backmixing phenomenon, and is dried evenly without the need for mixing.
Easy operation
The driving and parking operation of the dryer is very simple.
After stopping the feeding, the material scraper can quickly empty the material inside the dryer.
The special large-sized inspection door mirror allows for careful cleaning and observation of the equipment inside.
Low energy consumption
The material layer is very thin, the spindle speed is low, and the material conveying system requires less power and consumes less electricity.
Drying through heat conduction has high thermal efficiency and low energy consumption.
Environment protection
Atmospheric pressure type: The airflow velocity inside the equipment is low, and the humidity inside the equipment is high and low, making it difficult for dust to float to the top of the equipment. Therefore, the exhaust gas discharged from the top dehumidification outlet contains almost no dust.
Sealed type: Equipped with a solvent recovery device, it can conveniently recover organic solvents from moisture carrying gases. The solvent recovery device is simple and has a high recovery rate. For flammable, explosive, toxic, and oxidizable materials, protective gas can be used as a moisture carrying gas for closed-loop circulation, ensuring safe operation. Especially suitable for drying flammable, explosive, and toxic materials.
Vacuum type: A disc dryer operated under vacuum, especially suitable for drying thermosensitive materials.
Easy to install
The dryer is manufactured as a whole and transported as a whole. It only needs to be lifted and positioned, making installation and positioning very easy.
Due to the dry tray layout and vertical installation, even if the drying area is large, the footprint is very small.
