Design Specifications

DyMac is a drier from containers with dimensions: 12000 mm x 2400 mm x 2900 mm, designed to work in all weather conditions. It is a mobile drying system that can be used anywhere, provided it is supplied with electric or solar power. It is available in 3 formats: drier, storage unit, and drier-storage combo unit. DryMac can be stacked, allowing for use in places with limited physical spaces. Also, it can be configured to suit the available physical space and the bins can be modified into bulk bins, roll-in bins, bulk bags/crates or trolleys and trays to suit a user's needs. Primarily designed for drying macadamia wet nut in shell, it can be designed to dry other agricultural products including tobacco and some fruits. The drying system can operate by itself to dry products to a previously set moisture content. It can be managed remotely through a computer or a mobile phone app.
