Abstract
Heat exchanger is an equipment used to move heat between two fluids from high temperature fluid to low temperature fluid. This research goal is to knowing how heat exchanger process using differences pass, that will be 4,6,8 passes and four type volume flow rate, there are 0,023 m³/s; 0,028 m³/s; 0,030 m³/s; 0,032 m³/s using parameter from changing temperature of cold fluid, the heat that being accept by cold fluid, total heat transfer coeficient, heat exchanger efficiency and change of curing load mass in the form of cassavas using shell and tube type of heat exchanger, cross flow multipass mixed, finned tube. Cold fluid that use in heat exchanger is an air that given by blower and flow to the tubes. Inside the exchanger cold fluid experience increase temperature as a result of heat tranfer from the high tempered fluid from burner that use 3 Kg LPG gas fuel that flow from the other side of shell. Cold fluid that have receive the heat then flow to the rotary dryer to dry up the casava. From performancy experiment study of heat exchanger we have result that if we increase the number of passes up to certain amount must be followed with the increase of volume flow rate of 2 cold fluid to achieve changing high cold fluid temperature, bigger volume flow rate and more passes cause change of heat rate cold fluid that will be bigger. Total heat transfer coeficient decrease cause of more amount of passed but will be increase by the increase of volume flow rate number of cold fluid. Highest result from drying of cassava achieve by heat exchanger configuration with amount of six passes with 0,023 m³/s volume flow rate number. Heat exchanger efficiency will be increase by the increase of volume flow rate number and also more of passes that used.
