How to Dry Forsythia/Dehydrate Forsythia in a Dehydrator

Jul 17, 2021

Introduction to forsythia

  Forsythia suspensory blooms from March to April, and fruit period from July to September. It grows on hillsides, grasses, or valleys at an altitude of 250-2200 meters. The fruit can be used as medicine.

Forsythia drying process:

  First pick the harvested forsythia and put it on the plate. It is recommended to use stainless steel trays for higher drying efficiency. During the drying process, the temperature is set at 60°C for 1-2 hours without dehumidification, and the temperature is set at 55°C + dehumidification function for 3-12 hours. At this time, the dehumidification mode should be set according to the humidity. The later drying temperature of Forsythia is set at 65+timed dehumidification until it is completely dried. At this time, the baked forsythia is evenly dried, clean and pollution-free, and the appearance and dryness reach the ideal state. It is very important that the forsythia and medicinal ingredients are effectively preserved, and the energy-saving effect of the whole drying process is significant, and there is no Any discharge of pollutants.
The temperature is an important parameter during the drying process of Forsythia. Long-term experimental results show that the temperature setting of the heat pump dryer should not be too high or too low. When the drying temperature exceeds 65°C, the drying temperature will be too high, which will cause the dry skin to become hollow after being wet, and even scorch the forsythia, resulting in drug loss and quality degradation; when the drying temperature is too low, the drying will be prolonged Time, so the temperature is too high or too low is not good for drying Forsythia, usually the temperature between 20 to 65 is suitable.

Recommendation of forsythia dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation


  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
