Abstract
A motorised plantain chipping machine was developed. The machine is made up of a cutting device, a feeding mechanism, the support frame and an electric motor as a source of power. The cutting mechanism consists of the stainless steel blades, a connecting rod, a guide frame for the blades and pulleys. The blades are arranged perpendicular to the plantain tubers. During Performance Evaluation using Response Surface Methodology it was found that the chipping efficiency increased as the number of cutting blades are increased. Also the chipping efficiency increased with the speed of the machine but was not affected by the inclination angles of the blades. The linear effects of speed, the linear and quadratic effects of the number of blades significantly affected the chipping efficiency of the machine at 5% probability.
 
Razvijena je stabilna mašina sa električnim motorom za usitnjavanje trupaca (stabala). Mašina ima: uređaj (mehanizam) za sečenje (lopatice-sečiva), mehanizam za privođenje delova drveta, ram i elektromotor kao izvor energije. Mehanizam za sečenje sastoji se od specijalnih sečiva od nerđajućeg čelika, poluge, okvir za vođenje sečiva i remenice za pogon. Lopatice (sečiva) su postavljene normalno na pravac kretanja komada drveta (trupac). Tokom procene performansi mašine sa primenom metodologije određene površine utvrđeno je da se efikasnost sečenja povećava ako se povećava broj sečiva. Takođe se efikasnost sitnjenja drveta povećavala sa porastom broja obrtaja rotora na kojem se nalaze sečiva, ali na efikasnost nisu uticali uglovi nagiba sečiva. Linearni efekti brzine, linearni i kvadratni efekti broja sečiva značajno su uticali na efikasnost sečenja mašine za sitnjenje, sa verovatnoćom od 5%.
