Automatic Electromagnetic Drum Roaster – Flameless Oilseed Conditioning
Designed for the pre-press roasting stage of hot-press oil production, this electromagnetic drum roaster conditions oilseeds by unlocking aroma and reducing moisture — two factors that directly boost oil yield. The machine combines a heavy-duty frame, feed hopper, rotating drum and sealed heating chamber. A motor drives the drum through a V-belt and chain wheel, tumbling seeds continuously, while electromagnetic induction delivers adjustable flameless heat. One-button automatic control makes daily operation straightforward.
Three standard sizes are available — the 100#, the 130# and a thickened 130# — covering batches from roughly 160 kg up to 450 kg. Custom drum dimensions can be ordered to match your press throughput.

How It Works
The sealed drum heats up quickly and traps heat inside, while continuous rotation ensures every seed is heated evenly — no scorched bottom layer and no under-roasted top layer, which is exactly what good pressing oil demands. Heating power and roasting temperature are set independently and maintained automatically, with the machine shutting off once the target is reached.
Load & Set
Pour seeds into the feed hopper and set your target temperature and roasting time on the independent control panel. The drum begins rotating immediately.
Flameless Heating
Electromagnetic induction heats the drum wall directly — no gas flame, no coal smoke. Heat transfers uniformly through the sealed drum for consistent results.
Auto Shut-Off
When the set temperature or time is reached, the machine cuts off automatically. Open the discharge door and the roasted seeds flow out ready for pressing.
Key Advantages
Even roasting, no scorching
Drum rotation combined with flameless electromagnetic heating delivers a uniform roast throughout the batch, protecting oil flavour and colour from hot-spot damage.
Flameless and safe
Electromagnetic heating removes the open-flame risk of gas or coal roasters. No combustion means a cleaner workshop and lower fire insurance premiums.
Automatic one-button operation
Set temperature and time, then walk away. The machine runs the full roast cycle and shuts off by itself — no skilled operator required for routine batches.
Energy-efficient sealed drum
The sealed chamber heats fast and keeps heat inside, reducing energy waste compared to open-pan roasters. Real savings on every shift, especially with high electricity costs.
Suitable Seeds & Applications
This roaster handles all oilseeds typically roasted before hot pressing, and works equally well for nuts, grains and other food materials.
| Seed Type | Recommended | Notes |
|---|---|---|
| Sesame | ✓ | Aroma-focused roast for premium sesame oil |
| Peanut / Groundnut | ✓ | Even roasting for consistent groundnut oil flavour |
| Rapeseed / Canola | ✓ | Lower temperature to avoid burning |
| Sunflower Seed | ✓ | Good results across all three drum sizes |
| Flaxseed | ✓ | Gentle roast preserves nutritional value |
| Camellia / Tea Seed | ✓ | High-oil seed, well-suited to drum roasting |
| Nuts & Grains | ✓ | Versatile beyond oilseeds — food-grade roasting |
Frequently Asked Questions
What is the drum roaster used for?
It roasts oilseeds before hot pressing — the stage that brings out aroma and lowers moisture for a higher yield. Electromagnetic heating gives adjustable flameless heat, and the rotating drum turns seeds continuously for an even roast.
What sizes are available?
Three standard sizes — 100# (160–220 kg/batch), 130# (200–350 kg/batch) and a thickened 130# (360–450 kg/batch). Other sizes can be made to order to match your press throughput.
How is the temperature controlled?
Heating power and roasting temperature are set separately and held automatically, with shut-off when the set point is reached. One-button automatic control makes the daily routine simple.
Is it flameless?
Yes. Electromagnetic heating removes the open-flame risk of gas or coal roasters and keeps the workshop cleaner.
Which seeds can it roast?
All oilseeds roasted before hot pressing — sesame, peanut, rapeseed, sunflower seed, flaxseed, camellia seed and similar crops. It is also used for roasting nuts, grains and other food materials.
