Although the local sunshine is strong and windy, but Ivy mosses drying still need 3-4 days, in the process of drying, but also to avoid the hot sun affects its color, this air dryer is suitable for continuous shipment, to meet the needs of large quantities of processing, drying Ivy mosses does not yellow, high quality. Ivy mosses after drying is not only more convenient for transportation and storage, the added value of the product is also improved.

Drying process:

1. preheating stage: usually, Ivy mosses drying needs to be preheated before the preheating temperature of 45 ℃, the time is about 2 hours, Ivy mosses drying temperature requirements are higher than the ambient temperature, especially in the area of low temperature, preheating is more important. After the preheating stage and then slowly warm up to 60 ℃ or so.

2. constant temperature and humidity stage: after preheating, start to dehumidify for 2 hours, dry with 45 ℃, keep constant temperature and humidity inside the drying room, and keep the relative humidity in the drying room at 70%.

3. Timing dehumidification stage: after preheating and dehumidification for a total of 4 hours, the temperature rises steadily to about 55℃, drying mode, timing dehumidification (30 minutes per row, stop for 5 minutes), relative humidity of drying room is kept at 50% for a total of about 2 hours, and Ivy mosses starts to shrink and change color visually.

4. Heating and dehumidification stage: the temperature rises to about 60 ℃, the relative humidity of the drying room is maintained at 35%, a total of about 4 hours or so, slowly dehumidification, to maintain a certain degree of dryness.

5. Drying completion stage: the temperature rises to about 65 ℃, the relative humidity of the drying room is maintained at 15%, about 6 hours or so, until the Ivy mosses is completely dehydrated and dried.
