Abstract

Mango puree is a semi-finished product processed from mangoes. This mango puree is usually preserved using the freezing method or the method of adding preservatives. But actually this mango puree can also be preserved by the drying method. The advantage of the drying method over the freezing method is that it saves electricity and is more economical in manufacturing and operational costs. For this reason, in this research a mango puree drying machine will be created and tested using an LPG gas stove heating medium with a drying capacity of 5 kg / day. The air flowrate (debit) from blower was variated about halfly opened (HO) test and fully opened (FO) test. The research was carried out with the aim of knowing the heat balance of the drying machine and knowing the operational costs in the mango puree drying process. From the test results obtained, the amount of input energy in the LPG gas combustion process is 190.4 kJ and the amount of energy wasted is 133.29 MJ or around 77.6% of the input energy. The energy that is passed on to the heat exchanger is only 56.67 MJ or about 45.4% of the input energy. The total energy used in the mango puree drying process in the cabin is 29.38 MJ or about 22.4% of the input energy.
