Development and Test of Double Stage Cutting Machine for Black Tea

EasyChair Preprint 3456

Abstract

This experiment was conducted to create a prototype double stage cutting machine for black tea. The cutting machine consist 3 component; 1) main structure 2) motor power transmission using a 1.5 kW, speed of 1,450 rpm. and 3) cutting head. The cutting head consists of rough cutting part made from the grinding head no. 52 and the fine cutting part made from the grinding head no. 42. The components of cutting part are frame, spiral shaft, cutting blades and face plates. On the experiment, tea leaf shoots must reduce moisture content to 71.68 % by drying in room temperature for 18 hr and then massage with a cylindrical rolling machine for 20 min Formed tea shape by cutting was test by 2 treatment; 1^st cutting by using coarse pore of 20 mm and fine pore of 8 mm The 2^nd cutting by using coarse pore of 20 mm and fine pore 6 mm The 10 replications, of test with sample of each test of 5 kg. The result found that the machine can operate continuously without interruption while continuous cutting both the upper and lower heads. The capacity of machine to cut tea was 91.22 kg hr^-1 and 69.53 kg hr^-1 respectively.
