Biomass hot air industrial drying — timber, textiles and ceramics
The same technology, engineered for materials.
The core technology that dries mango to export specification serves manufacturing applications where controlled moisture removal determines product quality. The constraints differ — dimensional stability and internal stress matter more than colour and flavour — but the need for uniform, controllable, repeatable conditions is identical.
Indicative price of a biomass hot air generator, Ex-Works (EXW): USD 3,140–14,135
Shipping, customs clearance and local duties are extra. The final price depends on the configuration and is fixed in the written quotation.
Wood & timber
- Lumber drying — staged schedules reducing moisture to target while minimising internal stress, checking and splitting.
- Veneer — precise moisture control for reliable adhesive bonding, uniform across sheet dimensions.
- Species-specific schedules — hardwood and softwood require materially different ramp rates.
- Biomass fuel preparation — drying wood residue for use as fuel, often closing the loop within the same operation.
Textiles & fibre
- Yarn processing — controlled temperature gradients with tension management.
- Fabric finishing — uniform air distribution across full working width, the persistent engineering challenge in textile drying.
- Natural fibre preparation — cotton, sisal, jute and similar.
Ceramics & building materials
- Green-ware drying — slow, controlled moisture removal preventing shrinkage cracking.
- Temperature uniformity — differential drying across a piece is the primary cause of loss.
- Pre-firing conditioning — moisture reduction to the level the kiln requires.
Chemical & industrial materials
- Powder & granule drying — with appropriate containment.
- Safety-enhanced design — explosion-proof specification available where dust or vapour hazard requires it.
- Regulatory-compliance features — documentation and monitoring supporting audit.
Specification
These are the platform figures every configuration on this page is built from. The values specific to your product and volume are fixed at the sizing stage.
| Parameter | Value |
|---|---|
| Biomass burner | 200,000–900,000 kcal/h, PLC-controlled staged combustion |
| Accepted fuels | Pellets, 90 × 90 mm briquettes, cashew shell, crop residue |
| Hot air generator | Double chamber, three-pass, 2,500–3,000 m³/h |
| Delivered air temperature | 50–150 °C, controlled |
| Heat transfer | Indirect — combustion gases never touch the product |
| Drying chamber | 40–100 °C, 2.0–3.0 m/s, 1,500 kg per batch |
| Construction | 100 mm rockwool-core sandwich panel, 120-minute fire rating |
| Trays and wagons | SS304 stainless steel |
| Control | Delta PLC with recipe management, HMI, VFDs |
| Warranty | 12 months from date of shipment |
| Manufacturing lead time | 10–18 weeks from confirmed order and receipt of advance payment |
In prose: the burner runs from 200,000 to 900,000 kcal/h under PLC-controlled staged combustion, firing pellets, 90 × 90 mm briquettes, cashew shell or crop residue. The three-pass double-chamber generator moves 2,500 to 3,000 m³/h and delivers air between 50 and 150 °C, transferred indirectly so combustion gases never touch the product. Drying chambers hold 40 to 100 °C at 2.0 to 3.0 m/s with 1,500 kg per batch, built from 100 mm rockwool-core sandwich panel to a 120-minute fire rating, with SS304 trays and wagons. Manufacturing takes 10 to 18 weeks from confirmed order and receipt of advance payment, and the warranty runs 12 months from date of shipment.
Where this equipment is used
The same equipment is specified across several product classes. These are the ones it is configured for most often:
tree nut and oilseed drying and spice and botanical drying.
Each of those pages carries the drying parameters, cycle times and quality targets for that product class.
Where this sits in the range
This page describes one duty. The equipment itself is the biomass hot air generator, and the closest neighbouring duty is the agricultural-processing duty.
Frequently asked questions
Does drying non-food materials change the equipment?
The heat platform does not change — the same indirect double-chamber, three-pass generator moving 2,500 to 3,000 m³/h. What changes is that hygienic construction stops being the constraint and dwell time starts being it. Timber, ceramics and textiles all dry by diffusion through the material, so they reward long, stable holds rather than aggressive temperature.
What temperature range applies outside food drying?
The delivered air range is 50 to 150 °C, controlled, which covers timber conditioning, textile drying and ceramic pre-firing drying. It does not cover firing or curing duties that need substantially more than that. If your process needs above 150 °C, say so at sizing — the honest answer may be that this is not the right platform.
Can humidity be controlled as well as temperature?
It can, as an option, and for materials that crack it matters more than temperature does. Timber and ceramics fail by drying the surface faster than the core, which builds stress until something splits. Controlled humidity slows the surface down deliberately. It adds cost, so it is specified where the material warrants it rather than by default — the delivered air range of 50 to 150 °C is standard either way.
