BIOMASS DRYING PROCESS IN PELLET MANUFACTURING PLANT: TYPES OF DRYER & IMPORTANCE OF DRYING PROCESS.

Biomass drying process

🔍 Introduction

Drying is the backbone of biomass pellet manufacturing. Whether you’re using sawdust, wood chips, sugarcane bagasse, or rice husk, all biomass contains natural moisture that must be removed before pelletizing. FABON Engineering offers a complete range of high-performance dryers — Flash Dryer, Rotary Dryer, and Horizontal Dryer — to meet diverse industrial needs.

This blog explains:

  • The importance of drying in pellet production
  • The types of dryers available
  • FABON’s tailored dryer solutions for efficient and sustainable pellet manufacturing

🌿 Importance of Drying in Pellet Manufacturing

Why Drying is Essential

Biomass typically contains 30–60% moisture, depending on its source and storage conditions. This moisture must be reduced to below 10–12% before pelletizing.

🔧 Problems from Excess Moisture:

  • Poor pellet formation: Wet biomass can cause weak, brittle pellets.
  • Low calorific value: Moisture reduces combustion efficiency.
  • High energy consumption: Moist material uses more energy to compress and pelletize.
  • Pellet mill wear and damage: Wet feedstock strains dies and rollers.
  • Clogging and jamming: Inconsistent feed disrupts production.
  • Fungal/microbial growth: Moisture leads to biomass decay and health hazards.

Benefits of Proper Drying:

  • ✔️ Higher pellet density and durability
  • ✔️ Better fuel efficiency (more kcal/kg)
  • ✔️ Reduced machine maintenance
  • ✔️ Stable, long-term pellet storage
  • ✔️ Lower production cost per kg

Target moisture for pelletizing: 8–12%


🔄 Biomass Drying Process: Step-by-Step Overview

  1. Raw Material Feeding
  2. Hot Air Generation (using burner/furnace)
  3. Evaporation of Moisture inside drying chamber
  4. Dust and Particle Separation via cyclone or bag filter
  5. Discharge of Dried Biomass to pellet mill

🔧 Types of Biomass Dryers Offered by FABON

FABON Engineering offers three efficient dryer types, each optimized for different biomass materials, moisture content, and plant capacities.


1. FABON Flash Dryer

Ideal for:

  • Sawdust
  • Rice husk
  • Biomass powder
  • Agro waste fines

🛠️ Working Principle:

High-speed hot air instantly evaporates surface moisture from fine biomass particles as they travel through a drying duct.

🔍 Key Features:

  • Capacity: 300 kg/hr to 2 TPH
  • Output moisture: 8–12%
  • Heat source: biomass burner, LPG, electric
  • Dust collection via cyclone separator

📌 Benefits:

  • Very compact design
  • Fast and energy-efficient
  • Ideal for fine-grain, low-moisture biomass

2. 🔁 FABON Rotary Dryer

Ideal for:

  • Wood chips
  • Sugarcane bagasse
  • Paddy straw
  • High-moisture sawdust

🛠️ Working Principle:

Biomass is tumbled inside a rotating cylindrical drum while being exposed to hot air.

🔍 Key Features:

  • Capacity: 500 kg/hr to 5+ TPH
  • Moisture removal: up to 40%
  • Custom fuel: biomass, diesel, coal, LPG
  • Optional automation with temperature control

📌 Benefits:

  • Heavy-duty and durable
  • Handles coarse, sticky, or wet materials
  • Excellent for industrial-scale pellet plants

3. ↔️ FABON Horizontal Dryer (Conveyor/Belt Dryer)

Ideal for:

  • Uniform dryable material (chopped agro waste, leaf biomass)

🛠️ Working Principle:

Biomass moves over a heated conveyor belt. Hot air passes through the material from top or bottom, drying it gradually.

🔍 Key Features:

  • Capacity: 500 kg/hr to 3 TPH
  • Temperature control for precise drying
  • Ideal for delicate or specialty biomass

📌 Benefits:

  • Controlled and gentle drying
  • Modular for scalability
  • Suitable for high-end pellet plants
