THE TEMPERATURE CONTROL FOR SOLAR DRYING ROOMS BY AUTOMATIC SYSTEM

Abstract

The objective of this research has been increasing the efficiency of solar baking room of Somchan Community Enterprise, Uthong District, Suphan Buri Province. And had 3 steps to the operation, the first step was to collect information on requirements and studied the conditions for baking banana roll, the second steps was to designed and install the temperature control system in the solar baking room and the finally step was to comparison the operating results before and after the improvement. In which, before the temperature adjustment, the baking solar room must be has accumulated heat from the sunlight for an average of 3 hours and during the 7th hour, the temperature had continuously accumulates up to 75 degrees Celsius on average and it was also found that the locations of baking all 4 baking banana level had significant different temperatures.

The result of this research has been showing that an after adding temperature measurement systems and adding the automatic air flow control system to control the temperature inside the solar baking room, will be able to make the temperature inside the solar baking room has the average temperature not over 60 degrees Celsius and the temperature in the 4 levels of the banana baking roll are not significantly different.
