RANCANG BANGUN ALAT VACUUM DRYING DALAM PROSES PEMBUATAN TEPUNG MORINGA OLEIFERA LAMK

Abstract

Moringa oleifera lamk are trees with a height of up to 12m with a diameter of 30cm. The wood is a type of soft wood and has a low quality. And has many benefits, one of which is food, health, beauty and the environment.The working principle of this spinner type dryer is the material in the form of Moringa leaves frozen first using the freezer and then put into the dryer and dispatched the time that has been adjusted together with the hot air blower so that the drying process can take place quickly, after dispensing the Moringa leaves vacuum by using a vacuum pump to remove the water contained in the material so that the leaves of moringa are completely dry, the process continues until the leaves are completely dry and ready to be made flour, The variations carried out during the drying process take place are temperature and drying time so that it is known what water content and final weight of the Moringa leaf after drying. Vacuum drying appliance has been designed with the specification tool dimensions namely: 0.0020258m2 sectional area of the intake air, the rotation speed of 750rpm, power needed for 154watt, length 220mm V-belts V-belts with a speed of 3.925m/s. Produce Moringa leaf powder with a moisture content of 15% with the quality of green products (Moringa leaves), the fineness of the flour in accordance with the Indonesian National Standard quality of the flour (80mesh sieve), and the content of protein content is high at 28.84%.
