Technical And Economic Analysis Of Drying Garlic (Allium sativum L.) Powder Using A Rotary Dryer

Abstract

Garlic (Allium sativum L.) is a vegetable commodity that functions as a food flavoring ingredient and is also very beneficial for health. The high production of garlic in Indonesia causes the need for post-harvest treatment to maintain the quality of garlic and increase its economic value. The purpose of this study was to analyze technically and economically and to determine the feasibility of using a rotary dryer for drying garlic powder. The method used in this research is an experimental method. This dryer is a device that uses the concept of rotating drying by utilizing solar energy and biomass combustion as a heat source to increase the temperature of the drying chamber. The results showed that drying garlic powder using a rotary dryer was feasible, both from a technical and economic perspective. From the technical aspect, it can be seen that the best experimental results were obtained in the drying treatment at 55 oC with a thickness of 1 mm which resulted in a final moisture content of 5.88%, yield of 35.18%, working capacity of the tool 0.077 Kg/hour, effectiveness 0.534% and efficiency. 10.227%. From the economic analysis, it produces a B/C Ratio of 1.23, NVP Rp.714.495, IRR 7.59%, BEP is achieved at a production level of 40.1 Kg/year or for 522.4 hours/year and an economic efficiency level of 123.45% .
