Abstract

A heat exchanger is a device used to transfer heat from the system to another system without mass transfer and may serve as a heater or as a coolant. The purpose of this research is to know the effect of mass flow rate on Heat Exchanger Cross Flow Unmixed, Finned Tube Four Pass to temperature change, heat change, change of cold fluid heat transfer coefficient, total heat transfer change, heat exchanger efficiency change, and mass change of temulawak, with variation of mass flow rate 0,025kg/s, 0,029kg/s, 0,033kg/s, and 0,035kg/s. The operation of this Heat Exchanger is to utilize the flow of cold fluid out of the centrifugal blower, which then cold fuid into the Heat Exchanger, in the Heat Exchanger the cold fluid will receive the heat from the hot fluid flowing between the Heat Exchanger shell, where the hot fluid is sourced from the burner under the Heat Exchanger, after which the cold fluid that has received the heat comes from the Heat Exchanger to the engine medicinal dryer. The optimum drying result is obtained with cold fluid mass flow rate 0.029kg / s and with the result of herp mass change of 339 gram. If it is seen from the diagram of the influence of mass flow rate on the heat received cold fluid, and the diagram of mass flow rate influence on the change of temulawak mass it can be concluded that the change of cold air temperature (ΔTc) and cold air flow rate is the main factor in drying process Using the Heat Exchanger.
