Radial type motor driven bee honey extractor

A four frame radial type motor driven bee honey extractor was designed, fabricated and evaluated based on the recommendations of bee honey producers and designers of the old model extracting machine. It is composed of four main parts, namely: the cylinder collector, the primeover and power transmission group, the frame assembly and the support assembly. The device was designed to operate using 373 watts capacitor start-capacitor run electric motor capable of reversing the shaft rotation. All materials of construction exposed and in contact to the extracted bee honey were made of stainless materials. The device operates by the principle of centrifugal action where honey from the uncapped honey-combs throws out of its shell during rotation. Both sides of the comb were extracted radially orienting the frame assembly and rotating it in reversing directions. Analysis of data using 3 x 3 factorial experiment in completely randomized design and Duncan Multiple Range Test, the device has the observed highest extracting efficiency of 96.39% at 300 +/-5 rpm rotation of the frame assembly. Moreover, operating the device at 7 min duration yielded also the highest extracting efficiency of 96.39% at 300 +/-5 rpm rotation of the frame assembly. Moreover, operating the device at 7 min duration yielded also the highest extracting efficiency of 95.73% as compared to 3 min and 5 min duration. The highest performance efficiency obtained ranged from 86.27% to 87.70% at frame rotations of 250 +/-5 rpm and 300 +/-5 rpm, respectively. Also, operating the device at 5 min and 7 min duration yielded the highest performance efficiency range of 86.52-87.75, respectively. The device has a capacity of extracting four frames at a time with the highest observed value of 1.471 kg/min at 300 +/-5 rpm and 3 min duration. With respect to time of operation, the highest capacity observed was 1.321 kg/min at 3 min duration and with respect to the rotation of the frames, it was 0.953 kg/min at 250 +/-5 rpm. The minimum amount of honey to be extracted per year to justify the economic feasibility of using the device at a custom rate of Php5.00/bottle charge for extraction was 511.26 bottles with an 8 oz capacity
