Maintaining the right humidity levels is critical to preserving the quality, flavour, and shelf-life of nuts and coffee during processing, roasting, packaging, and storage.
At Moisture Cure, we deliver tailored humidity control systems designed specifically for the Australian climate and the demanding needs of nut and coffee producers.

The Role of Humidity in Nut Processing
Nuts are highly sensitive to moisture. During harvesting, drying, and storage, uncontrolled humidity can lead to:
- Mould and fungal growth, especially in macadamias, pistachios, and walnuts
- Aflatoxin contamination caused by high moisture levels
- Rancidity and oil breakdown from oxidation in fluctuating environments
- Shell cracking or shrinkage when conditions are too dry
To counter these issues, our dehumidification systems maintain consistent relative humidity (RH), often between 50–60%, depending on the nut variety and stage of processing. Our desiccant dehumidifiers are particularly effective in low-temperature drying rooms, ensuring safe and efficient moisture extraction without the risk of overheating.
Coffee Processing & Storage Demands
Coffee beans are just as susceptible to moisture damage. From green bean storage to roasting and final packaging, even minor variations in humidity can lead to:
- Loss of aroma and volatile oils
- Bean swelling or contraction during roasting
- Inconsistent roast profiles
- Mould formation in green bean storage
- Clumping and spoilage in ground coffee packaging
For roasters and coffee producers, we provide refrigerant dehumidifiers to manage warm environments, and ducted systems for facility-wide climate control.
In green coffee warehouses, maintaining RH around 55–65% is essential to prevent degradation. For roasting rooms and packaging lines, RH needs to drop closer to 45–50% to ensure optimal performance and prevent moisture absorption into the final product.
Custom Solutions for Every Step of Production
No two facilities are the same. Whether you’re storing bulk raw almonds in a regional warehouse or running a commercial coffee roastery in a humid coastal zone, our solutions are tailored to your exact requirements. We consider:
- Room volume and insulation
- Local climate and seasonal swings
- Moisture output from equipment
- Required RH for each product and process
- Airflow, filtration, and zoning
Our systems can be installed as standalone units, integrated with HVAC, or built into drying chambers and roasting areas.
Designed for Australian Conditions
Australian processors face a unique mix of challenges—from dry inland heat to tropical coastal humidity. Our systems are engineered to perform in these extremes, ensuring stable conditions year-round, even when temperatures and ambient humidity swing dramatically.
We also work closely with food safety, HACCP, and export requirements to help facilities stay compliant while maintaining product integrity.
