Koolmill is recognised as the 3rd generation (nextgen) cereal (rice) milling technology. Using a super-efficient coated abrasive and internationally patented milling chambers to replace stones, screens, augers, displacement plates and air systems. Koolmill is a flexible and scalable, low power (80% power saving) cold milling process. A simple concept: rice, driven by the abrasive, circulates within the chamber, progressively and controllably removing the surface from the kernel with minimal heat, loss or damage.

Rice is gravity fed to the chambers and husk/bran removed collects naturally in the voids between chambers. Rice and husk/bran are discharged separately by gravity. The consistent (non-pulsing) milling pressure is controlled by physical control parameters set to achieve optimum output. Eliminating wasted power, results in minimal temperature rise. The gentle Koolmill process can be set to improve health outcomes by increasing the nutritional quality of rice outputs; fully milled long-grain embryo retaining rice retains 67% of the nutritional value of the brown rice. A higher specification cleaner bran by-product increases its value for use in high protein/carbohydrate human food products. By simply adding or removing chambers or varying the width of the abrasive it is possible to scale up or down to meet specific customer needs. Thus, the same high-performance technology, available to the largest mills, is now available to even the smallest millers.

Traditional 2nd-generation machines use high power motors to compensate for their inherent inefficiency. They are attritional, treating rice as a solid, and mechanically generate destructive pulsating milling pressures. They all do something to the rice, resulting in wasted power, heat, thermal stress, mechanical stress, lost and damaged rice (Food Loss). Koolmill is unique in that the rice is treated as a fluid. Milling chambers work with the rice to dynamically generate a gentle, consistent and controllable milling pressure. Koolmill eliminates augers, stones, screens and weighted displacement plates where much of the damage and loss occurs.

Koolmill USP’s: Low power (80% saving), low loss, low damage, low temperature milling. Simpler mills with less complex infrastructure and capital costs. Fully automatic optimised milling with access to real time data, remote monitoring and auto-tuning delivers more food and profitability from existing rice harvests.
