Why do you need to dry ginger?
The ginger sold in our vegetable market is sold directly after a simple cleaning. However, fresh ginger has a high moisture content, so the preservation time of fresh ginger is not very long. Rotten ginger contains toxins and is not suitable for consumption. Fresh ginger has a limited storage time. In order to ensure long-term storage, storage, and transportation, ginger needs to be dried. Ginger can be processed into ginger slices, ginger powder, and other products.
Ginger slice drying technology
The raw material for drying ginger can be fresh ginger or ginger. The ginger used should be undamaged and without holes.
Wash the ginger and slice it
Wash the selected ginger with water and slice it. The thickness of the cut ginger slices can be controlled within 3~5mm.
Put onto the tray
Place the cleaned and sliced ginger slices on the tray, paying attention to the even space between the two slices of ginger, not overlapping.
The drying of ginger slices roughly goes through three stages: drying, dehumidification, and constant temperature drying.
(1) The temperature is set at 70°C, and the time is 2 hours. This stage is mainly dry.
(2) The temperature is set at 60°C for 18 hours, mainly for drying and dehumidification.
