Vapour Heat Treatment uses hot humidified air to eliminate fruit fly eggs and larvae. The process exposes fruit to carefully controlled temperature and humidity conditions that elevate internal fruit temperature without causing heat damage.
Unlike chemical fumigation methods, VHT leaves no chemical residues. Temperature, humidity and treatment duration are automatically controlled and recorded to ensure treatment effectiveness, repeatability and complete traceability. The technology is recognised internationally as a safe, reliable and environmentally responsible quarantine treatment solution.
FruitoLine HHAT represents RINAC’s advanced approach to thermal disinfestation. The system uses controlled heat and humidity to raise the internal pulp temperature of mangoes while protecting flavour, freshness, colour and nutritional characteristics.
The process typically raises fruit pulp temperature to approximately 46–48°C while maintaining humidity above 95%. Continuous monitoring and automated controls ensure treatment consistency. Following treatment and holding phases, fruits undergo cooling and drying processes that stabilise quality and prepare them for storage and export.
Global demand for safe, premium-quality fruit continues to grow. Consumers increasingly seek chemical-free produce with high traceability and superior shelf life. At the same time, importing countries have strengthened quarantine requirements to prevent the spread of invasive pests and diseases.
Mangoes are particularly vulnerable because fruit fly infestation can lead to shipment rejection and market restrictions. Vapour Heat Treatment (VHT) and Humidified Hot Air Treatment (HHAT) technologies have emerged as internationally accepted quarantine treatment methods that eliminate fruit fly eggs and larvae without relying on chemical fumigation. Exporters can therefore comply with international regulations while preserving fruit quality, colour, flavour, texture and nutritional value.
A modern export operation requires much more than packing fruit into cartons. Exporters must maintain a controlled process from orchard to destination market. Critical requirements include pest disinfestation, export-quality grading and sorting, shelf-life preservation, cold chain management, traceability, documentation and compliance with international protocols.
A single fruit fly detection can disrupt international trade and result in significant financial losses. Advanced infrastructure reduces risk while improving operational efficiency and export acceptance rates.

The HHAT/VHT system continuously monitors fruit pulp temperature, chamber temperature, humidity, heating cycles, cooling cycles, drying cycles, fan operation, humidification performance and alarm conditions.
The HMI enables recipe selection, process monitoring, diagnostics and compliance verification. Automated data logging creates an auditable treatment history that supports export certification and customer assurance.
Treatment alone does not guarantee export success. To facilitate export success, RINAC integrates pre-cooling facilities, cold rooms, refrigeration systems, ripening chambers, insulated processing environments and reefer transportation infrastructure.
Following treatment, mangoes are stored under controlled conditions, typically around 12–13°C depending on fruit variety and operating requirements. Proper temperature management helps preserve nutrients, extend shelf life and maintain export quality.

Head Cold Chain
Our pack house facilities consisting of integrated pack house at Horticulture Centre of Excellence, Sairang Mizoram, and 5 nos satellite units at 5 district headquarters that are designed and manufactured by Rinac using High Performance Composite Construction (HPCC) technology with insulated structures are lightweight and they have gone through all-weather seasons and found intact. We experience a substantial reduction in heat and sound from the wall panels and roofing during monsoon. It also provides ease of cleaning. We appreciate and congratulate Rinac for providing such a solution that is faultless to this sensitive terrain of Mizoram.
Directorate of Horticulture
We would like put on note that Rinac India Limited have the expertise in executing jobs on turnkey basis and we express our sincere thanks for the support rendered by them in associating and completing this project from Concept and having no hesitation in referring them to prospective customer in all segments having Cold Chain requirement. We wish them all the best and look forward to work with them in all our future Cold Chain requirements.
