High-capacity Rotary Drum Dryer for Cow Manure with 10%-15% Moisture Content and Pathogen Sterilization

Rotary drum dryer for cow manure

1.Product Introduction

A Rotary Drum Dryer for cow manure is specialized, high-capacity thermal equipment designed to process fresh poultry waste. Raw chicken manure has a high moisture content (typically 60%–80%) and strong odors. This dryer utilizes high-temperature airflow to rapidly reduce moisture to 10%–15%, while simultaneously sterilizing pathogens and eliminating odors, transforming a foul waste product into a valuable, nutrient-rich organic fertilizer.

2.Application

• Organic Fertilizer Granulation: Preparing dried, pathogen-free manure powder that is ready to be granulated into commercial organic fertilizer pellets.

• Commercial Soil Amendments: Manufacturing sterilized, weed-seed-free soil conditioners for agriculture, horticulture, and landscaping.

• Biomass Fuel: Drying poultry litter to be used as a co-combustion fuel in specialized waste-to-energy biomass boilers.

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.
