Rancang Bangun Mesin Pengering Bawang Kapasitas 7 Kg

Abstract

After a review of the onion farmers, an obstacle was found in terms of drying the harvested onions, where the constraints were weather factors which could change every time as high as slowing down the drying process, therefore researchers were interested in creating an efficient onion drying machine using fire heat sources as the dryer, this design aims to create an onion drying machine with a capacity of 7 kg and to design an onion drying machine in order to get a real shape from the drying machine, the purpose of this design is to find out whether the machine can dry the onion and find out if there is the difference between dry onions if using sunlight and using a drying machine and the difference in coolers and the amount of moisture in the onion, the method used in this design is to make an initial image which then assembles the grinding machine ng to reduce the water content in the onion. The material used in the work process is angled iron measuring 25 x 25 mm and a plate with a thickness of 1.5 mm and the material for the work process is onion which is still wet. By using a drying machine, the results obtained in one production take 1 hour and the evaporated water content is 10.97% using a temperature of 70 0C. Onions which are dried by using the same machine using sunlight, only different drying times.
