Development of A Friction Type Garlic Separator
마찰식 박피마늘 선별기 개발
Abstract
Both the wet and dry types of garlic peeling machines are being presently used in domestic garlic processing factory, but the dry type is more popular than the wet type because of higher peeling efficiency. The peeling efficiency of these machines is estimated 50 to 80%, depending on the difference in garlic varieties, physical properties and moisture content of garlic samples. If the peeling time is increased in order to improve the peeling efficiency, the damage on the surface of peeled garlic and the consumption of electric power are also increased. This study was carried out to solve these problems in garlic peeling operation and to obtain the optimun design factor for the friction type separator. The results are summarized as follows : 1. The average friction coefficients of peeled and unpeeled garlic samples were 0.91 and 0.51. respectively, for the acrylic plate, and 0.96 and 0.51, respectively, for the stainless plate. 2. For the inclined acrylic pipe with the pipe length 90 cm, the inclined angle
