ABSTRACT:
The great difficulty for family farmers who produce food organically is the control of weeds without using chemical products. One possibility for the management is the use of heat in the sense of coagulating the protoplasm in leaves and stem cells. The present research aimed toconceptual design a mechanized system for weeds control through the use of heat focusing on familiar farmers who produce food organically. In this study, we used a product development methodology which can be divided into different stages that are composed of several tasks. As a result of the use of such methodology, six concepts of heat transfer machines were developed. After the application of selection tools, two concepts were chosen for the optimization process, and then the one considered ideal to meet the needs of farmers was selected.
