Rotary Drum Dryer for Sugarcane Bagasse with 50% Moisture Reduction and High-Temperature Airflow for 10%-15% Moisture Content

Rotary drum dryer for sugarcane bagasse

1.Product Introduction

A Rotary Drum Dryer for sugarcane bagasse is a highly efficient, heavy-duty thermal drying system designed to process the fibrous, wet sugarcane waste left after juice extraction. Fresh bagasse typically contains about 50% moisture, making it difficult to burn and prone to fermentation. This dryer utilizes advanced internal flight designs and high-temperature airflow to rapidly reduce the moisture content to 10%–15%, transforming a wet by-product into a valuable, stable biofuel or industrial raw material.

2.Application

• Sugar Mill Cogeneration: Pre-drying bagasse to feed the mill's boilers, significantly boosting combustion efficiency to generate green electricity and steam.

• Biomass Pelleting & Briquetting: Preparing raw bagasse fibers to the exact moisture levels required to press them into high-density fuel pellets.

• Pulp & Paper Manufacturing: Drying bagasse to be stored and processed into eco-friendly paper, packaging, and tableware pulp.

• Animal Feed & Composting: Processing bagasse into dry, sterile dietary fiber for livestock feed or organic fertilizer bases.

3.Working Principle

The dryer operates on a continuous, tightly sealed heat exchange mechanism:

• Feeding: Wet coal is continuously fed into the slightly inclined, rotating cylindrical drum.

• Cascading & Drying: Internal lifting flights and chains lift the coal and shower it through the hot air stream. This constant movement breaks up clumps and creates a uniform curtain of coal, allowing rapid heat transfer and moisture evaporation.

• Discharge & Safety Control: The dried coal slides to the lower discharge end. An induced draft fan pulls the moist air out through a cyclone and baghouse filter to capture fine coal dust. Safety systems, such as inert gas injection or explosion relief valves, are often integrated to manage combustible coal dust safely.
