Larvae drying systems encompass the thermal dehydration equipment and process engineering required to convert live or pre-treated insect larvae, predominantly Black Soldier Fly Larvae (BSFL), mealworms (Tenebrio molitor), house crickets (Acheta domesticus), and lesser mealworms (Alphitobius diaperinus) from their high-moisture biological state at harvest into a stable, dry material that can be stored, transported, and further processed without quality deterioration or microbial spoilage. While the drying technology principles are related to those applied in food and biomass drying, larvae drying has several distinct engineering requirements that differentiate it from these adjacent applications: larvae are living or recently blanched organisms with complex internal moisture distribution; their fat content is both high and commercially valuable, requiring temperature management to prevent oxidative damage; and regulatory compliance requirements for thermal pathogen reduction are mandatory, not optional, in virtually all commercial markets for insect-derived products. Kerone Engineering Solutions provides larvae drying systems that address all three of these distinctive requirements within a robust, food-grade, industrially reliable equipment platform.
Why Choose Kerone Larvae Drying Systems
Kerone’s position in the larvae drying market is grounded in its experience across multiple insect species and production scales, from 200 kg/h farm-scale installations to 3,000+ kg/h industrial facilities. This breadth of experience has enabled Kerone’s engineering team to develop detailed process knowledge of the differences in drying behaviour between species, BSFL’s high fat content and chitin cuticle thickness, mealworm larvae’s different internal moisture distribution, cricket’s fragile exoskeleton requiring gentle handling and to configure its larvae drying systems accordingly rather than applying a single generic configuration across all species. Kerone also brings to larvae drying its broader expertise in food-grade equipment construction, hygienic design, and regulatory compliance documentation, which are increasingly important as insect protein markets mature and regulatory oversight intensifies.
Types and Features of Larvae Drying Systems
Kerone’s larvae drying system range is centred on continuous belt dryers in single-band, double-band, and triple-band configurations, matched to the specific throughput requirements and product handling characteristics of each insect species. Single-band systems are suitable for fragile cricket and mealworm larvae where the mechanical handling of multi-band transfer would cause excessive product damage. Double and triple-band configurations are preferred for BSFL, where the cascading transfer between belts provides beneficial tumbling that exposes fresh moisture-bearing surfaces without physical damage to the robust larval cuticle. All Kerone larvae drying systems incorporate the blanching or steam pre-treatment stage upstream of the drying belt, providing pathogen reduction validation within the same process train rather than requiring a separate equipment stage.
Key Features
Species-specific configuration with single-band (fragile species: cricket, mealworm) and multi-band (robust species: BSFL) belt options, preventing physical damage while maximising moisture removal efficiency
Integrated blanching or steam pre-treatment stage upstream of the drying belt, achieving regulatory thermal pre-treatment within the same equipment train and eliminating additional handling steps
Low-temperature drying capability at 55–80°C limiting lipid oxidation and protein denaturation in the drying process, preserving the nutritional quality and commercial value of the dried larval product
Validated thermal treatment documentation with batch-linked time-temperature records satisfying EU Regulation 142/2011 processed animal protein requirements and equivalent international standards
Enclosed system design with odour exhaust deodorisation, managing the volatile fatty acid and sulphur compound emissions inherent in larvae thermal processing
Variable belt speed and adjustable loading depth enabling throughput adaptation to accommodate the biological size variation in larvae batches from different rearing compartment ages
Food-grade stainless steel construction throughout with hygienic weld quality, eliminating crevices where larvae residues and fat deposits could accumulate and harbour microbial growth
Post-drying cooling section integrated into the equipment train, reducing product temperature to below 40°C before discharge to packaging or downstream processing to prevent moisture re-absorption

Frequently Asked Questions (FAQ)
Freshly harvested BSFL typically contain 60–70% moisture. Mealworm larvae range from 55–65% moisture. Cricket larvae are in the range of 65–75%. All species require drying to below 10% moisture for commercial stability.
Kerone's belt dryers are designed with adjustable bed depth and belt speed, allowing operators to compensate for size variation by adjusting residence time. Larger larvae require longer drying time for moisture to migrate from core to surface.
Pre-blanching before drying is strongly recommended for both quality and regulatory reasons. Blanching inactivates autolytic enzymes, reduces initial microbial load, and contributes to total thermal treatment accumulation required for PAP compliance. Direct live larvae drying produces lower quality dried product.
Larvae drying emits trimethylamine, dimethyl sulphide, volatile fatty acids, and ammonia. Kerone's enclosed, negative-pressure system routes all exhaust through a biofilter or thermal oxidiser, reducing emissions to levels acceptable under standard industrial facility air discharge permits.
The chitin cuticle creates a moisture barrier that slows internal moisture migration to the surface. This means even moisture distribution across the product bed is critical, areas of thin bed depth dry faster than thick areas, requiring cross-flow air distribution to compensate.
For markets where whole dried insects are approved for human food use, Kerone's food-grade construction, validated thermal treatment, and hygiene design meet the standard required. Applicable novel food approvals in the target market must be confirmed independently.
Minor lipid loss occurs as surface fat drips from larvae during heating, typically 2–5% of total fat content. Kerone designs drip collection trays beneath the inlet drying zone to recover this fat fraction for separate processing.
Co-drying of different species is not recommended in facilities producing certified single-species products, as species identity may be required for regulatory labelling compliance. Kerone designs facilities for either single-species dedicated lines or multi-species sequential operation with appropriate changeover cleaning.
Kerone's largest standard larvae drying systems process up to 3,000 kg/h of fresh larvae. Larger capacities can be achieved through parallel operation of multiple lines. Modular expansion units can be added to existing installations.
Post-drying cooling in an enclosed tunnel reduces product temperature to below 35°C before discharge. Packaging in moisture-barrier bags or containers with nitrogen purge immediately after cooling prevents moisture re-absorption during packaging and storage.
Human food-grade larvae drying requires higher hygiene construction standards (food contact material compliance, electropolished surfaces), stricter microbiological process management, and more comprehensive quality documentation. Animal feed grade requires regulatory thermal treatment validation and ATEX consideration where applicable.
Kerone recommends daily dry cleaning of accessible surfaces and weekly CIP cleaning of the full drying system for continuous production operations. The frequency may increase for operations processing moist or high-fat larvae that deposit more residue on belt and dryer surfaces.
Yes. Kerone can design larvae drying systems that operate on diesel generator power or solar-diesel hybrid power systems for installations in regions without reliable grid electricity supply, specifying appropriate electrical components for the available power quality.
Drying BSFL from 65% to 8% moisture achieves a weight reduction of approximately 65–70% — meaning 3 kg of fresh larvae produces approximately 1 kg of dried product. Moisture reduction from higher or lower inlet values changes this ratio proportionally.
Yes. Kerone provides on-site commissioning including process optimisation runs with the client's larvae, operator training covering normal operation, cleaning procedures, maintenance tasks, troubleshooting, and safety procedures. Ongoing support is available through Kerone's after-sales service programme.
