Traditional Figs -drying process
Coal as fuel or electric heating air to dry the figs is one of the traditional drying process. Due to the temperature, humidity and air circulation cannot be effectively controlled, resulting in high energy consumption and labor cost, also, drying quality is not guaranteed
Moreover, the hygiene of drying process cannot meet the requirements of food production.
Heat pump dryer in figs drying process features
Heat pump dryer absorb the heat from the moisture in exhaust hot air, and then release these heat in condenser to heat the drying air again. Only compressor power is request that means power consumption is few.

Figs Heat Pump Drying Process
Fresh fig moisture content is as high as 78%; selection, cleaning and slicing
are some necessary pre-drying process to ensure the quality of dry goods
Recommended figs heat pump drying process as follows,
Selection and washing
Select ripe figs, remove rotten figs and other impurities, and rinse with water, cut off the fig stems.
Cut fig into four to six pieces to increase the contact surface between fig slice and hot air , shorten the drying time.

Heating pump drying process
Pay attention that ventilation and dehumidification while temperature rising, so as to facilitate moisture evaporation.
1st, Raise the temperature to 75℃quickly(in one hour) and keep temperature @ 75～80℃, humidity less than 50% for 4 hours, to accomplish most amounts of water evaporate in a short time.
2nd, keep temperature @ 65～70℃, humidity less than 30% for 8 hours,
3rd, keep temperature @ 60～65℃, humidity less than 10% for 4-6 hours. Final dried fig slices will have 14-15 moisture.
Cover the dried figs with plastic film and let them soften for 2-3 days.
