The Continuous Heat Pump Dryer is engineered for high-throughput industrial operations where product must flow through the drying process uninterrupted, eliminating the loading and unloading downtime inherent in batch systems. In Kerone’s continuous configuration, wet product is fed into one end of the dryer and travels through progressively drier and thermally controlled zones before being discharged at the target moisture content from the opposite end. The heat pump module or more commonly, a cascade of heat pump stages, manages the temperature and humidity profile along the length of the drying tunnel, recovering latent heat from moisture-laden exhaust air and redirecting it as sensible heat to the incoming drier air streams. This zone-by-zone psychrometric management allows Kerone to precisely engineer the drying curve gradient to match the product’s falling-rate drying characteristics, preventing case hardening in the outer layers while ensuring adequate moisture migration from the core. The result is a continuous process that delivers consistent product quality at throughput rates ranging from a few hundred kilograms per hour to several tonnes per hour in large industrial installations.
Why Choose Kerone Continuous Heat Pump Dryer
Kerone’s continuous heat pump dryers are the product of extensive computational fluid dynamics modelling and real-world commissioning experience across food, chemical, and mineral processing industries. Our design process begins with detailed process flow analysis, product sampling, and laboratory-scale drying trials to establish the drying curve before the production system is specified. This data-driven approach ensures that the number of drying zones, air recirculation configuration, heat pump staging, and conveyor dwell time are correctly matched to the product’s actual thermal and moisture transport behaviour is not estimated from generalised tables. Kerone also offers remote process monitoring and optimisation services post-commissioning, allowing our engineers to fine-tune zone setpoints and conveyor speeds based on production data collected over the initial weeks of commercial operation.
Types and Features of Continuous Heat Pump Dryer
Kerone designs Continuous Heat Pump Dryers in conveyor belt, vibrating conveyor, and moving bed configurations depending on the product’s physical form and fragility. Multi-zone designs with independent heat pump modules per zone provide the highest degree of flexibility, while single-module designs with internal zone dampers are cost-effective for products with predictable, uniform drying behaviour. The conveyor structure is fabricated from SS-304 or SS-316 with perforated or wire mesh belt options to ensure adequate through-air circulation for granular, pellet, or slab products.

Frequently Asked Questions (FAQ)
Residence time is controlled by adjusting the conveyor belt speed through the variable frequency drive controller. Longer residence times are achieved by reducing belt speed, and shorter times by increasing it, allowing the same machine to handle different products or moisture targets.
Kerone's continuous dryers are equipped with inlet product level sensors or weighing belt feeders that communicate feed rate variations to the PLC, which then adjusts conveyor speed and zone temperatures proportionally to maintain constant outlet moisture content.
Yes. Kerone offers non-stick PTFE-coated conveyor belts for sticky products, and low-vibration smooth-running conveyor drives for fragile or brittle products. Belt tension and tracking are managed automatically to prevent product spillage.
Typically, Kerone's continuous heat pump dryers consume between 0.25 and 0.45 kWh per kilogram of water evaporated, compared to 0.8 to 1.2 kWh/kg for conventional hot-air tunnel dryers, representing savings of 50–70%.
Each zone has its own temperature and humidity setpoints managed by independent PID control loops in the main PLC. The operator selects a saved product recipe that automatically loads all zone setpoints, conveyor speed, and fan speed parameters.
Kerone engineers continuous heat pump dryers from small-scale units processing 100 kg/hr of wet product up to large industrial systems handling 5,000 kg/hr and above, with belt widths from 600 mm to 3,000 mm.
Kerone designs all tunnel sections with hinged or removable access panels on both sides for inspection and cleaning. Conveyor belts are designed for rapid removal and wash-down, and the heat pump module is accessible from the utility corridor for refrigeration maintenance.
Yes. Kerone provides custom infeed and outfeed integration engineering, including product transfer conveyors, weight monitoring stations, and interlocking control signals to upstream and downstream process equipment.
For products with compatible drying parameters, a controlled transition is possible by introducing the new product while the previous product clears the dryer. For products requiring significantly different temperature or humidity profiles, the dryer is run empty on the new recipe for one full residence time cycle before the new product is introduced, ensuring the chamber reaches steady state.
Depending on the target drying temperature and chamber volume, start-up to stable operating conditions typically takes 30 to 90 minutes. Kerone's control system manages the warm-up sequence automatically, including gradual compressor load-up and progressive temperature setpoint ramp to avoid thermal stress on the chamber structure.
Yes. Kerone's variable frequency drives on fans and the conveyor, combined with modulating heat pump compressor capacity, allow the dryer to operate at 40–100% of rated capacity. Reduced capacity operation is managed through a proportional scale-down of conveyor speed and air flow to maintain product residence time and outlet moisture target.
Kerone's PLC tracks the position of product in the dryer from infeed to outlet using a virtual product tracking function. Product that was in the dryer during a temperature deviation or start-up transient is flagged at the outlet for quality hold and separate assessment, preventing out-of-specification product from entering the normal flow.
Kerone's continuous dryers can receive product from vibratory feeders, screw conveyors, rotary spreaders, and belt feeders. The infeed system selection depends on product form, required layer depth uniformity, and production line layout. Kerone provides infeed system engineering as part of the complete system design.
Kerone sizes the heat pump with sufficient installed capacity to handle the worst-case high-moisture scenario, typically the peak harvest season for agricultural products. During lower-moisture periods, compressor capacity modulation prevents over-drying and energy wastage while maintaining efficient operation.
Large continuous dryers require a reinforced concrete floor slab designed for the distributed equipment load, typically 3–6 tonnes per linear metre of tunnel length. Kerone provides a foundation loading drawing and civil specification as part of the project documentation package for the client's structural engineer.
