Frying is one of the oldest processes for cooking and drying of food. The frying process is basically the exchangeof thermal energy through direct contact between a transferring heat medium and the food in high temperature. The frying process is the most commonly used oil as frying medium, however in this research used sand as a medium for transferring heat. Even though frying process is a very popular and ancient method to cook foods, the theory of frying processing was long neglected and poorly understood. The objective of this research was to develop a mathematical model of heat and mass transfer, to better explain coefficient of unit surface conductance (h) between food (chip) andABSTRAKPenggorengan  merupakan  salah  satu  metode  tertua  dari  proses  pemasakan  dan  pengeringan  pangan.  Prosespenggorengan berlangsung melalui kontak dengan media penghantar panas dan dilakukan pada suhu tinggi. Proses penggorengan biasanya digunakan minyak sebagai media penghantar panas, akan tetapi pada penelitian ini digunakan pasir sebagai media penghantar panas. Meskipun penggorengan merupakan suatu proses pemasakan pangan yang sudah lama dilakukan, tetapi proses tersebut banyak yang belum diungkap secara ilmiah.Tujuan dari penelitian ini adalah untuk mengembangkan model matematik pindah panas dan massa yang meliputi koefisien kontak panas
