Open-Fire
Drum Roaster
A rotary drum roaster with an open-end design and direct-fired heating —
easy loading and observation while evenly roasting peanuts, sesame and other oilseeds.
Why Roasting Matters Before Oil Pressing
Proper roasting softens cell structures, develops characteristic oil flavors and prepares materials for efficient extraction — directly impacting yield, aroma and final product quality.
Improve Oil Yield
Heating softens cell structures and helps release more oil during pressing, maximizing recovery from each batch.
Enhance Oil Aroma
Proper roasting develops the characteristic flavor of edible oils — essential for peanut, sesame and specialty oil production.
Increase Pressing Efficiency
Conditioned materials are easier to process, reducing energy consumption and improving throughput in downstream equipment.
Improve Product Consistency
Uniform roasting ensures stable production quality with repeatable results across every production run.
Working Principle
The open-type fire-heated drum roaster tumbles seeds inside a rotating drum heated directly by a coal, biomass or gas fire. The open drum end allows quick loading, discharge and visual checking of the roast.
Key Features
Engineered for uniform seed conditioning with precise temperature control in continuous industrial production.
Uniform Heating
Even heat distribution throughout the roasting process for consistent seed conditioning.
Adjustable Temperature Control
Configurable roasting temperatures suitable for peanut, sesame, sunflower and other oilseeds.
Continuous Operation
Designed for commercial and industrial production with stable, uninterrupted processing.
Energy Efficient Design
Optimized heating system reduces fuel consumption while maintaining consistent roasting quality.
Durable Construction
Heavy-duty industrial-grade materials built for long service life in demanding environments.
