    Design, construction, and performance evaluation of a Bee Pollen Drying machine
    (Don Mariano Marcos Memorial State University - North La Union Campus, 2010-03) Vidad, Sheraldine B.; Orodio, Rommel O.
    This study was conducted to design, construct and test the performance of a bee pollen drying machine in terms of its capacity and efficiency. The design of the bee pollen drying machine is directed toward the realization of a mechanical air dryer that would meet the drying requirement for bee pollen. The design was prepared at the Agricultural Engineering Department. The device was constructed at the AIRSTREAM Trading and Electro Mechanical System Corporation, located at Annex 37 Better Living Subdivision, Paranaque City, Metro Manila from November, 2009 to January, 2010. It was tested at the crop processing center of the Agricultural Engineering Department on February 13 and 14, 2010. The principal parts of the device are the following; heater, fan, dual function temperature / humidity controller, dumper, stoppering, fiber glass, and wheels. The total cost of the machine is forty six thousand five hundred nine pesos and ninety two centavos (P46,509.92). The drying temperature treatments were used as follows: T1 = 35oC of 4 drying trays T2 = 40oC of 4 drying trays T3 = 45oC of 4 drying trays Analysis of variance using ANOVA was used to determine the significant difference between treatments. Tukey’s method was used to further test the significance. Analysis of variance showed highly significant difference between treatments on the rate of moisture reduction per hour, and the 35oC treatment resulted highly significant and thus efficiency as far as quality of dried products is concerned. The 35oC treatment revealed the most efficient and desirable color, texture, and aroma of dried bee pollen. Analysis of variance on the quality of products revealed highly significant difference. This finding showed that maintaining a temperature of 35oC to 40oC of drying bee pollen will result to a favorable and desirable dried product.
