The high-quality solution is realized by continuous drying of highly concentrated solutions under a vacuum.
The continuous vacuum drying system dries high viscosity liquid that is difficult to process by spray drying type at low temperatures, and producing the highly soluble dried products in a short time.

Drying System

• In the vacuum tank [1] of the main body, while operating by the cold trap and the vacuum pump [2], the vacuum degree below 10Torr is kept.
• The raw materials in high concentration and high viscosity in the form of the liquid, slurry, and paste are uniformly dispersed in thin layer form on the belt [4] which is operated by the raw material supply facility and the uniform dispersion nozzle [3].
• There are three heating plates [5] and a cooling plate [6] on the underside of the belt, when the material on the belt passes through the heating zone, it dries at a low temp.
  In this case, the thin membrane raw material evaporates violently the internal water forms a porous format with a large number of vents in the interior as well as swelling.
• When being cooled down in the cooling zone the product temp. drops, it hardens, and arrives at the end of the belt.
• In the end, the granules are primarily pulverized with the pre-crusher [7], which is attached to the top of the vacuum tank, and the main crusher [8] pulverizes them again to produce the best soluble porous granules.

Features

1. High-quality dried products can be produced in a short time

• Low-temperature drying around 40℃ is ideal for heat-sensitive raw materials, excellent in solubility and restorability.
• The raw materials are hygienic and prevent oxidation because it is dried and pulverized in a vacuum tank.
• Less scattering loss of raw materials and products, resulting in dry products of the same amount and same quality as raw materials.

2. High efficiency and economical drying

• The selection of the drying rate according to the physical properties enables high concentration and high viscosity drying in the form of the liquid, slurry, and paste.
• Continuous drying is more efficient than batch type.
• Design considering heat efficiency and drying efficiency, minimizing incidental equipment such as exhaust and drainage to reduce costs.
