Introduction

The Hybrid Belt Dryer is a continuous drying machine in which wet material is spread on a slow-moving perforated conveyor belt and carried through one or more insulated drying chambers, while hot air is blown through the product layer. Because the material rests on the belt without tumbling, the dryer treats fragile, pasty and extruded products very gently, preserving their shape, colour, aroma and active components. Multiple belt passes or decks can be stacked to save floor space and lengthen residence time. In its hybrid form, the dryer draws heat from combined sources, such as steam or thermic fluid heaters with electric trimming, or a heat pump module with conventional heating, and lets each chamber be set to a different temperature. This makes the belt dryer an efficient, highly controllable option for continuous production of products that need a uniform, gentle and predictable drying profile.

Why Choose Kerone Hybrid Belt Dryer

Consistent belt drying depends on proper feed distribution, even air through-flow and well-designed belt mechanics, all areas where Kerone applies its decades of dryer-design knowledge. We begin with your product’s form, whether it is paste, extrudate, flake, granule or cut piece, and design the feeding, spreading and layer-depth system to give an even bed. Belt material, such as stainless steel mesh or food-grade polymer, is chosen for temperature, hygiene and cleaning requirements. Airflow is zoned for upward and downward passes so that top and bottom layers dry alike, and heating sources are matched to your utilities to cut operating cost. Our units include belt tracking, automatic cleaning options, easy-access doors and complete automation. As a single-source supplier of feeders, dryers, coolers and control panels, Kerone ensures a smoothly integrated, dependable continuous drying line.

Types and Features of Hybrid Belt Dryer

Kerone offers the Hybrid Belt Dryer as single-belt, multi-pass and multi-tier designs, with through-flow air in either upward or downward directions, or both in alternating zones. Feed systems range from rotary distributors and oscillating spreaders to extruder-fed pelletisers and dosing screws. Belts are available in stainless steel mesh, perforated plates or polyester and food-grade polymer fabrics, in different mesh sizes. Chambers are modular, with separate fans, heaters and dampers so that each zone can run at its own temperature and humidity. Common features include a variable-speed belt drive, automatic belt tracking and tensioning, a cleaning system for the belt, insulated panels, a cooling section if required, and a PLC with recipe control. Heat sources include steam, thermic fluid, hot water from heat pumps, gas, biomass and electricity in useful combinations.

Key Features

  • Continuous, gentle conveying that preserves the shape and quality of delicate or extruded products
  • Hybrid heating sources, such as steam or heat pump with electric, to lower fuel cost and improve temperature stability
