| Abstract | ||
| An innovative unit has been constructed and tested for scraping honeycombs at Meet-Salseel, EL-Dakahliyah, Egypt. Scraping results in facilitating extraction of the maximum quantity of honey from the honeycombs. The main objective of this study is to solve the scraping problem by innovative a simple and easy operating unit for scraping honeycombs, by removing the caps without waste of honey, with minimum time and less number of labors. The innovative unit consists of a rectangular wooden frame attached by collecting tank. The innovative unit was compared to the conventional methods that included serrated stainless steel knife and a special scratcher. The experiments included three positions of scraping edges (horizontal, inclined and V-shape) and three blade angles (15, 30 and 45º). Scraping efficiency, weight of scraping part, scraping duration time and total cost were measured. Results showed that, the maximum value of scraping efficiency (100 %) was achieved with the simple innovative unit at V-shape position with 45º of blade angle. The minimum weight (92 g.) of scraping part was achieved by the simple innovative unit at horizontal position with 15º of blade angle. The minimum value of scraping duration time (22 sec.) was achieved by the simple innovative unit at V-shape position with 45º of blade angle. The innovative unit saved about 61.82 and 71.23 % of the operating cost compared to the conventional methods (serrated knife and scratcher), respectively. It is recommended to use the simple innovative unit at V-shape position, 45º of blade angle and in a hot room or at about 01:30 to 03:30 pm. to lessen the viscosity of honey. | ||
