The temperature is controlled at 30°C 35°C at the beginning of the drying process, and the temperature is increased to about 40°C after 2 hours.
After another 5-10 hours drying, the temperature was raised to 45°C-50°C and the temperature shall be maintained for 10 hours. Afterwards, the temperature is raised to 55°C- -58°C, and the maximum shall not exceed 60C. The total drying time is 24 hours.
If the temperature is too high or too fast, the flower buds will turn black and the quality will decrease. If the temperature is too low and the drying time is too long, the color will not be fresh, and the color will turn in yellowish white, which will also affect the quality. On cloudy and rainy days, the honeysuckle must be dried at low temperature. First, it should be dried at 35C and 40° for 2-3 hours, and then the temperature should be raised to 50 degrees. In general, 6-7 kg of dried flowers could be dried into 1 kg of dried honeysuckle product.
