Rotary dryer for thermo sensitive products

Abstract

Drying is a fundamental process for the conservation of biological products with high water content, such as medicinal plants. This process favors the maintenance and integrity of the chemical constituents responsible for the therapeutic effect of these plants.1 The conservation is possible because the drying process reduces the water content to values less than 10% (wet base), and inhibit the microorganism’s growth and the enzymatic reactions, guarantying safety, stability, long expiration date.1,2 Moreover, it reduces the initial volume, facilitating transportation with cost reduction and creates conditions for a safe and extended storage.
