Laju Pengeringan Kentang Kering (Solanum tuberosum L.) dengan Menggunakan Tunnel Dehydrator

Abstract

The purpose of this study is to obtain the drying rate of dry potatoes that have the best color quality and moisture content by treating the temperature and size of the potatoes tested. This drying uses a Tunnel Dehydrator to get a combination of temperature and size treatment of potatoes by color analysis and water content to get the best treatment and drying rate. The results of this study get the drying rate y = -0.013x + 5.0433 and the coefficient of determination (R²) of 0.9539 or 95.39% with the best drying treatment at a temperature of 70˚C with potato thickness 1 x 1 x 1 cm, yield 14.1%, moisture content 10.26 % and chroma value 23.35 (very good)
