The GENEX Continuous Band and Apron Dryers, engineered by GENEX Tech Industries LLP (Food Tech Projects), offer high-efficiency continuous drying solutions across the food, pharmaceutical, chemical, and biomass sectors. Designed for 24/7 continuous operation, these advanced conveyor belt systems utilize precise multi-zone temperature controls and optimized airflow engineering to ensure uniform moisture removal, maximum energy efficiency, and gentle handling for heat-sensitive materials.
What is an Industrial Band / Apron Dryer?
An Industrial Band Dryer (also called a Belt Dryer or Conveyor Dryer) is a high-efficiency continuous drying system. It removes moisture from wet materials while they are systematically transported through a controlled, insulated, multi-zone drying chamber on a moving conveyor belt or metal apron.
Working Principle
The system operates on the principle of convective hot air drying through a staged process:
Feeding: Wet material is distributed evenly onto the moving conveyor belt or apron.
Transportation: The material passes sequentially through multiple independently controlled drying zones.
Moisture Evaporation: Heated air is circulated continuously through the product layer to evaporate internal moisture.
Exhaust: The moisture-laden air is efficiently captured and removed through an exhaust system.
Discharge: Fully dried material is continuously discharged at the outlet.
Key Technical Specifications
The standard systems offered by GENEX feature highly customisable parameters:
Dryer Type: Continuous Band Dryer / Apron Dryer
Capacity: From small-scale up to large industrial throughputs (100 kg/hr to 10 TPH / Tons Per Hour)
Heating Methods: Steam, Hot Air Generator, Thermic Fluid, or Electric Heating
Drying Zones: Single-zone or Multi-zone design configurations (multi-pass configurations are also available for compact layouts)
Construction Materials: Mild Steel (MS), SS304, or SS316 food-grade stainless steel depending on application requirements
Control Systems: Manual, PLC, or SCADA automation
Key Advantages & Features
Uniform Product Quality: Multi-zone temperature, airflow, humidity, and belt speed controls provide precise staged drying and consistent final moisture targets.
Energy Efficiency: Features low heat loss insulated chambers, optimized air circulation, and heat recovery/energy optimization options to reduce operating costs per kg of product.
Gentle Drying: Designed specifically for heat-sensitive materials or products requiring long residence times with high initial moisture contents.
Low Maintenance: Built for heavy-duty, 24×7 continuous industrial operations with long-life belt systems.
Main Components of a GENEX Band Dryer System
The continuous belt drying system is engineered from several tightly integrated sub-systems designed to balance air pressure, retain heat, and transport materials seamlessly:
Product Feeding System: Ensures the wet material is evenly and uniformly distributed across the width of the moving conveyor belt. This prevents product clumping and ensures uniform air penetration.
Conveyor Belt / Apron System: The heavy-duty transport mechanism (available in various configurations like stainless steel wire mesh or perforated plates) that carries the product continuously through the drying zones. It features adjustable speed controls to fine-tune product residence time.
Multi-Zone Drying Chamber: A heavily insulated, low-heat-loss housing structure where the actual moisture evaporation takes place. It is divided into distinct, independent thermal sections.
Hot Air Generation / Heating System: The thermal powerhouse of the system. It supplies precisely controlled hot air using the plant’s choice of energy: Steam heating, Thermic fluid heaters, Hot air generators, or Electric heating elements.
Exhaust & Air Circulation System: Utilizes high-efficiency blowers (and specialized turbine-type fans with variable speed drives) to continuously recirculate hot air up or down through the product bed while exhausting moist, evaporated water vapor at an optimized rate.
Control System: The command center, featuring manual, PLC, or SCADA automation panels. It monitors and regulates live parameters including temperature zones, airflow distribution, belt speed, and total drying time.

Industries We Serve
The GENEX Band/Apron Dryer line is engineered to process diverse material formats (slices, dices, granules, flakes, and fibrous structures) across these key sectors:
Food & Agro Processing: Dehydration plants for fruits, vegetables (onion, garlic, ginger), spices (turmeric, chilli), starch, cassava, noodles, vermicelli, and specialty products like high-fat desiccated coconut and extruded snack pellets.
Pharmaceutical & Nutraceutical: Continuous drying of delicate herbal extracts, botanical leaves (moringa, seaweed), nutraceutical powders, granules, and intermediates.
Chemical & Industrial Process: Processing of heat-sensitive industrial compounds, resins, specialty chemical powders, pigments, dyestuffs, and industrial salts.
Biomass & Recycling: Drying of agricultural residues, biomass materials, wood chips, sawdust, organic waste, recycled plastic flakes, and rubber crumbs.
Paper & Textile: Large-scale continuous moisture removal from paper pulp, cellulose-based materials, fabrics, yarns, and textile fibers.
Why Choose a GENEX Band Dryer?
GENEX systems focus heavily on thermal efficiency, structural hygiene, and mitigating standard processing risks (like “case hardening”—where the outside of a product dries too fast and traps moisture inside).
40+ Years of Engineering Expertise: Built by an established manufacturer with proven turnkey global installations across Asia, Africa, and international markets.
Advanced Airflow & Complete Uniformity: Engineered with multiple airflow direction changes and air reversals that force air down or up through the product bed, eliminating wet spots and ensuring identical final moisture targets.
Independent Multi-Zone Thermal Control: Features separate temperature controls per zone. This allows operators to gradually lower the air temperature as the product dries, preventing overheating, burning, or discoloration.
High Thermal Efficiency & Heat Recovery: Built with highly insulated chambers to minimize thermal loss. Systems can be integrated with advanced heat recovery loops to re-utilize exhaust air heat, significantly slashing fuel consumption and operating costs per kg of product.
Hygienic, Export-Grade Construction: Built using food-grade SS304 or SS316 stainless steel (with optional Clean-in-Place / CIP integration), fully meeting global standards as an ISO 9001:2015, CE, and US FDA certified company.
Continuous 24×7 Heavy-Duty Operation: Designed to replace slow, labor-intensive batch drying systems with fully automated PLC/SCADA operations that require minimal operator intervention.
