Here are a few steps to dry chrysanthemum flowers:& nbsp;& nbsp;
1.  & nbsp; & nbsp; Picking chrysanthemums:
Picking, the flower picking time is once after early September, accounting for about 60% of the yield, followed by a second picking every 5-7 days, accounting for 30% of the yield, and another picking after 7 days, accounting for 10% of the yield.
Harvesting criteria: When most of the flowers are open, the color is bright yellow, the petals are straight, and the flower center is scattered, it is considered timely and graded. Huai chrysanthemum usually has high requirements for the appearance and appearance of the finished product, so the key to control is to lock the natural color of the material. Therefore, the temperature should not be too high and the dehydration speed should not be too fast. There are two commonly used drying equipment for Huai chrysanthemum, one is static drying, that is, box drying room. Another type is dynamic drying, which is a mesh belt dryer
1.  & nbsp; & nbsp; Drying of Chrysanthemums:
On the same day of harvesting and processing, the processing technology directly uses a sulfur free drying room for dehydration and drying, preserving the original appearance, color, natural aroma, and effective ingredients of chrysanthemum flowers. Chrysanthemums can be directly placed on the drying tray of the drying cart, with multiple layers placed at once. After all are placed, the drying cart can be pushed into the drying room for drying.
The box type drying room adopts a hot air circulation supply method with a hot air blower, ensuring even circulation of hot air. The hot air source is sent out by a circulating fan through a heater, and then sent into the drying room through an air duct. The used air is sucked into the heater to become the hot air source and circulated again for heating. Ensure indoor temperature uniformity. When the temperature value swings due to the action of opening and closing the door, the air supply circulation system quickly resumes operation until it reaches the set temperature value.
