PERENCANAAN AGITATOR PADA PABRIK ES KAPASITAS 30 TON PER HARI

Abstract

In an ice factory, the method used is a simple method. The method used is the cooling water in the mold with salt water. To make water into ice, salt water flow required to absorbtion heat, so there is need for agitators to drain the salt water. Agitator is a tool for stirring / flow of salt water that has been through the evaporator which has a lower temperature (cold) and channeled through the ice mold that has a higher temperature (heat). Agitator made so that the process of heat transfer from the water in a mold can be absorbed by the salt water that flows. Based on calculations and observations that have been made to the planning agitator on the ice factory capacity of 30 Tons per day, obtained agitator dimensions. Dimension agitators, divided in several parts. At the shaft, shaft 7,5 cm. For dimensions key, width 22 mm and 14 mm thick. Dimension to the clutch, clutch 150 mm, 112.5 mm long clutch, bolt circumference 225 mm and 37,5 mm thick flange couplings. While bearings are used with no. 215 with the size, in 75 mm, outer width 130 mm and 25 mm long bearings. In the axial flow agitator head of planning and mapping of triangular blade speed of 10.352 M. To estimate the cost of 1 unit for USD $ 6,800,000.00 agitator. This estimate does not include the cost of agitator motor
