Abstract:
Turmeric (Curcuma domestica VAL) is a rhizome plant that is very popular as a spice and as a medicinal ingredient. The form of turmeric that can be used is in the form of fresh turmeric, dried turmeric, or turmeric powder. Turmeric drying produces dry turmeric, which has a longer shelf life and makes packaging easier. One of the dryers that can be used to dry turmeric is a heat pump dryer. In this study, the water content of the turmeric simplicial product was tested at various heating times, i.e., 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, and 8 hours with a constant temperature of 400C. The final water content of the dry turmeric product reached 7.53%.
