Abstract

Setelah jangka waktu penggunaan yang panjang, silika gel akan jenuh dengan kelembaban dan kehilangan efektivitasnya. Oleh karena itu, dehidrasi silika gel menjadi penting untuk memulihkan daya serapnya melalui proses pengeringan. Tujuan penelitian ini untuk menganalisis sisi fenomena perpindahan panas dan massa terhadap kinerja proses dehidrasi. Jenis perlakukan yang diamati adalah suhu dan waktu proses sebagai variabel bebas, tingkat tray sebagai variabel kendali, kadar air dan free mositure sebagai variabel terikat. Silika gel yang digunakan adalah Fuji Davison Tipe A sebanyak 4 kg. Berdasarkan hasil analisis kesetimbangan energi, proses dehidrasi pada tekanan vakum -30 cmHg (0,6 atm) dikendalikan oleh radiasi termal sebesar 41,71 % berasal dari radiasi melalui dinding dan kolektor radiasi, kontribusi konveksi sebesar 1,05 % dan konduksi 7,57 %.
