Overview

The HG series drum scraper wastewater crystallizer is widely used in industries such as food wastewater, chemical wastewater, medical wastewater, etc. for the production and drying of viscous and paste like materials.

Product Details

One,Double drum scraper wastewater crystallizerfeature：

▲ Using steam or thermal oil as the heat source, the heating area is large, the thermal efficiency is high, and the heating is uniform.

▲crystallizationThe speed is high, and the heat and mass transfer processes of the wet material film on the cylinder wall are consistent from the inside out direction. The temperature gradient is large, which maintains a high evaporation intensity on the surface of the material film.

▲crystallizationShort time, usuallyAbout 7-30 seconds, suitable for heat sensitive materials.

▲ Easy to operate and maintain.

Three,Double drum scraper wastewater crystallizeroperation mode:

Produced by Fan Jun CompanyrollerscraperformulaWastewater crystallizerMachine is an internally heated conductive rotary continuous drying equipment. The rotating drum adheres to a certain thickness of material film through its lower material groove, and heat is transported to the inner wall of the drum through pipelines, conducted to the outer wall of the drum, and then transmitted to the material film, causing the moisture in the material film to evaporate, dehumidify, and preventing the moisture containing material from drying. The dried material is removed from the drum by a scraper installed on the surface of the drum, and then transported to a screw conveyor placed below the scraper. The dry material is then collected and packaged by the screw conveyor.

Heat and mass transfer during drum drying process:

Coating film on the surface of the cylindercrystallizationThe basic principle is based on the thermal resistance between the cylinder and the film, forming a temperature gradient. The heat inside the cylinder is conducted to the film, causing the moisture inside the film to transfer outward. When the vapor pressure on the outer surface of the film exceeds the vapor partial pressure of the ambient air, evaporation and diffusion occur. During the continuous rotation of the drum, the heat and mass transfer of the film adhered to each revolution always occur in the same direction from the inside out.
