Overview

Zinc acetate vacuum dryer is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and a scraper stirrer is used to continuously remove the materials on the hot surface, forming a circulating flow in the container. After the water evaporates, it is extracted by a vacuum pump. It is commonly used in organic semi-finished products and fuel drying operations in the chemical industry.

Product Details

Product Introduction

Zinc acetate vacuum dryerThe device uses a steam jacket to indirectly heat materials and exhausts them under high vacuum, making it particularly suitable for drying materials that are not resistant to high temperatures, are prone to oxidation at high temperatures, or are prone to powder production during drying (such as various fuels), as well as materials that require the recovery of steam or solvents removed during the drying process.

Zinc acetate vacuum dryerThe moisture content or solvent content of the dried material in the middle reaches as high as 90%, while the lowest is only 15%. The dried material can be in the form of slurry, paste, granular, powdery, or fibrous. The moisture content of these materials after drying generally reaches 0.1%, or even 0.05%.

The dried material is added from the center of the shell, and under the stirring of the constantly rotating rake teeth, the surface of the material constantly updates when it comes into contact with the shell wall. The dried material is indirectly heated by steam, causing the moisture in the material to vaporize. The vaporized moisture is promptly extracted by a vacuum pump. The machine can use both sandwich and rake teeth heating methods simultaneously, with a larger heat transfer area and higher thermal efficiency, resulting in higher drying efficiency. Due to the high degree of vacuum operation, the surface water vapor pressure of the dried material is much higher than the water vapor pressure in the evaporation space inside the drying machine, which is conducive to the discharge of internal and surface moisture of the dried material, and facilitates the movement of water molecules in the dried material to achieve the purpose of drying.

Note: The evaporation rate of water is related to the characteristics of the material and the temperature of the hot air inlet and outlet. When the outlet temperature is 90oC, the water evaporation curve is shown in the above figure (for selection reference). As the product is continuously updated, relevant parameters may change without prior notice.
