The day-lily drying base in Qidong County, which are located at Hunan Province, uses Shuntec heat pump drying machines to solve the farmer’s problems, i.e. unable to control the firewood’s temperature for drying. It uses 1 set of 5-hp drying equipment units equipped with a polyurethane drying room of 60 square meters for operation.
The drying process are as follows: Putting a baking tray, which could holds day-lily 5 kg for each square, into a drying room with the temperature of 75 ℃.
