Vacuum Rake Dryer

Vacuum Rake Dryer

Product Overview

This dryer features a simple structure, easy operation, long service life, stable and reliable performance, low steam consumption, strong applicability, and high-quality product, particularly suitable for drying paste materials that are intolerant to high temperatures, flammable, and prone to oxidation under temperature adjustment. Proven by long-term use by customers, it is a reliable drying equipment. Principle: The material to be dried is added at the center of the top of the shell. Under the continuous forward and reverse movement of the scraper teeth, the material moves axially back and forth, constantly renewing the surface that contacts the inner wall of the shell. It receives indirect heating from the steam, uniform mixing by the scraper teeth, and crushing by the粉碎棒, facilitating the removal of moisture from the material surface. The vaporized moisture is then passed through a dry dust collector, a wet dust collector, and a condenser, finally being released at the outlet of the vacuum pump.

       It enjoys advantages as easy & convenient operation, long life circle, stable & reliable performance, low steam consumption, strong adaptability and good quality which are especially applicable for drying paste materials which cannot resist high temperature, flammable and is easy to be oxidized under temperature adjusting. It is proved to be a good drying device after long-time use by the users. The principles are: add the materials to be dried from middle of upper part of the shell body. The materials move in axial direction back and forth under positive and negative rotation of the rake (stirring). The surface which contacts with inner wall of the shell keeps renewing. Under indirect heating of the steam, even stirring by the rake and crushing by the crushing bar, it is easier for water on material surface to be discharged. The gasified water is emptied at outlet of vacuum pump by dry-type collector, wet type collector and condenser.
