A wind tunnel type orchid moisture removal machine was fabricated to replace an using fan blowing direct at the orchid for moisture removal of newly cut orchids prior to packing for export, Especially during rainy season when orchids contain high moisture. The prototype machine composed of a moisture removal chamber with dimensions of 1.2 x 7.5 meter (width x length), a cross flow fan with diameter of 40 centimeter and the length of 1.2 meter driven by a 2 horsepower electrical motor, and a conveyor to transport orchids into the chamber driven by a 0.5 horsepower,an electrical motor with speed reducer gear box. The conveyor is capable of moving in 2 directions; along or against wind direction.Temperature inside the chamber could be controlled by using temperature sensor and a control unit mounted at the side of the machine. The time for moisture removal by the prototype machine and the ordinary direct showing at orchid were compared quality of orchid after moisture removal was determined. Results showed that the prototype machine could reduce moisture removal time by approximately 50 percent compared to the ordinary fan blowing. Quality of orchids after moisture removal from the prototype machine was not affected.
