Drum dryer is a kind of large-scale continuous drying equipment whcih developed exclusively in China after years of research and experiment by our factory. The whole set of equipment is composed of coal-fired hot air furnace, feeding and discharging equipment, rotary drum dryer, dust removal system, electric control system, high and low temperature pipes and other mechanisms.In view of the characteristics of high moisture and high viscosity materials, such as high moisture content, high sugar content and easy to bond, a series of unique technologies and processes were adopted, which solved various technical problems in the drying process of dregs and achieved good drying effect.

3. Features

• The range of moisture reduction is large, and the wet materials with moisture content up to 82% can be dried to less than 13% moisture at one time.
• Unique high temperature drying grid internal structure (patented technology), improve heat exchange rate, high drying efficiency, low energy consumption, good drying quality.
• Equipped with high-efficiency coal-fired hot air furnace and perfect insulation measures, the thermal efficiency is greatly improved.
• Large capacity, single set of equipment can handle 80-500 tons of wet materials every day
• It can be used not only for drying fresh apple pomace, but also for distiller's grains, compound fertilizer and other materials with poor dispersion and large moisture.
• The unique head and tail seal design reduces the secondary pollution to the environment, improves the energy efficiency utilization and saves the operation cost.
• The drum is equipped with a strong disperser, which can effectively solve the problems of binding and caking of slag like materials in the drying process. This technology has obtained national patent.
• The drum is equipped with a strong disperser, which can effectively solve the problems of binding and caking of slag like materials in the drying process. This technology has obtained national patent.
• The design and manufacture of the relevant components all consider the requirements of ensuring the mechanical performance when working in the long-term high temperature state, and can ensure the long-term continuous full load drying operation.
• The mechanical chain type coal-fired hot blast furnace is used as the heat source of the drying system. The coal-fired hot blast furnace has strong adaptability to coal types. The grate is continuously variable transmission, the coal combustion is fully complete, and the overall thermal efficiency of the hot blast furnace can reach more than 90%. The coal loading and slag discharging of the furnace are mechanized operation, stable operation and convenient operatio
