Effect of Air Speed and Drying Capacity On the Tongkol Fish Crackers Drying Machine

Abstract

Research on the influence of air drying speed on crackers has been carried out by Siregar, M.S., Anggara, M., Aldrin, A., & Hidayat, A. (2023) where air speed influences the value of drying rate, air content value and drying efficiency value , the higher the air speed, the greater and more efficient the drying rate, air content value and drying efficiency value. Meanwhile, research has never been carried out on testing the capacity of a drying machine for mackerel fish crackers to determine the capacity of a drying machine according to the size of the machine, namely with dimensions of 40 cm long, 40 cm wide and 85 cm high. The aim of this research was to determine the effect of air speed and drying capacity on drying rate, air content and drying efficiency on a tuna cracker drying machine. This research uses an experimental drying method using a tuna cracker drying machine by testing air speed and drying capacity. From the test results, the best drying rate between the two was at a speed of 2,5 m/s with 100% capacity. The best water content is at a speed of 2 m/s with a capacity of 50% and a capacity of 75% and at a speed of 2,5 m/s with a capacity of 50% and a capacity of 75% (according to the 12% cracker water content standard, SNI 0272:1991) as well as drying efficiency the best between the two is at a speed of 2,5 m/s 100% capacity.
