Abstract
Heat is developed specifically for insect control. In addition to that moisture on the mangoes is also controlled. The temperature and exposure time are adjusted to kill all stages of fruit fly infected produce. The treatment consists of a period of warming which can be faster or slower depending on a commodity’s sensitivity to high temperatures. Then there is a holding period when the interior temperature of the produce reaches the desired temperature for the length of time required to kill the insect. To regulate the speed of the fan, the temperature sensor and moisture sensor are defined as inputs to the microcontroller. Taking in the temperature and moisture values, the Arduino thus defines a control strategy. It is a crucial step to control the speed of the fan and the heating coil temperature as it may over dry the mangoes or under dry them resulting in a loss and spoilage of quality.
