Wood Pellet Fired Heat Exchanger is an eco-friendly and cost-effective heating solution widely used in food processing for frying, roasting, and drying. By switching from Diesel or LPG to wood pellets, factories can reduce their fuel costs by 60% to 70%.

In Ahmedabad, these systems are typically designed as Indirect Fired Heat Exchangers, where the combustion of pellets happens in a separate chamber, ensuring that no smoke or ash touches the food.

1. Technical Specifications

  Heat Transfer: The hot flue gases pass through a Shell and Tube or Fin-type Heat Exchanger.

  Medium Heating: The secondary medium (Air for dryers or Edible Oil for fryers) circulates around these tubes, absorbing the heat.

  Exhaust: Cleaned exhaust gases are released through a chimney, while the ash is collected in a bottom tray for easy disposal.

Key Benefits for Food Plants

• Huge Savings: Wood pellets cost approx. 10–12/kg compared to LPG at  90+/kg.
• Clean Flame: Pellets produce minimal ash 2% and no sulfur or oily odors, maintaining food hygiene.
• Stable Heat: Unlike wood logs, pellets have a consistent density, providing a very steady temperature which is critical for frying snacks like Namkeen or Potato Chips.
• Easy Retrofit: Most pellet burners can be attached to your existing gas/diesel fryer or tray dryer with minimal modification.
