Referring to the figure there is illustrated a low temperature dryer (10) where the central element of the dryer is a cold aerosolizer (11) having an infeed auger (12) from an infeed bin (13) and an air inlet (14) and a product, aerosol and air outlet duct (15). The core aerosolizer comprises a central shaft (16) and a plurality of blades (17). The outlet duct then carries the partially dried material, the aerosol and the air into a cyclone (18) where the plant material is extracted while the air and the aerosols flow to a condenser (19) where the liquids are removed. The dry air is discharged at an outlet (20) of the system. The expression "low temperature" referred to herein means a temperature, normally ambient, but can be above ambient, such as to minimise heat degradation of nutritional factors in the product or products being processed.
