Abstract

Cashew (Anacardium Occidentale) is a kind of industrial trees having high economic value[2]. In some countries over the world such as India, Brazil, Mozambique, Tanzania, Malaysia, Nigeria, and Philippines ... are countries manufacturing Cashew. In Vietnam the statistical number of total quantity of Cashew after processed is 200.000 (ton/year). Using the husk as material to torrefy Cashew and working in unsuitable condition causes a lot of polluted air. This polluted air contains high quality of petroleum [4], otherwise the temperature is rather high (from 150°C to 200°C) [5] so that absorbing methods used in practical is un-efficient [1]. The Incinerating method we promote will be suitable with cashew's polluted air.
