Efficient Chrysanthemum Drying With Hot Air Oven

Introduction

Working principle

The working principle of using a hot air circulation oven to dry chrysanthemums is as follows: The heating system generates hot air, and the circulating fan evenly distributes the hot air inside the oven, allowing the hot air to continuously flow over the surface and inside the chrysanthemums, accelerating the evaporation of moisture. The evaporated moisture is promptly discharged outside the box through the dehumidification system, while fresh hot air continuously replenishes and enters, thus forming a stable hot air circulation environment. By precisely controlling temperature, time, and wind speed, chrysanthemums can be dried evenly, quickly, and with low loss, while maintaining their color, shape, and active ingredients.

The chrysanthemums dried using a hot air circulation oven have the characteristics of good color retention, relatively intact flower shape, and uniform drying. At the same time, they can retain their natural aroma and effective components, such as flavonoids and volatile oils. Due to the drying process carried out in a closed and temperature-controlled environment, the hygiene conditions of the chrysanthemums are higher, they are less prone to contamination, and their moisture content is stable, effectively prolonging the storage time and reducing the risk of mold growth, making them more suitable for use in tea beverages or medicinal processing.

FAQ

Q: What is a hot air circulation oven used for chrysanthemum drying?
A: It is a controlled drying system that uses circulating hot air to remove moisture from chrysanthemums evenly and efficiently.

Q: Why use a hot air oven instead of natural drying?
A: Hot air ovens provide faster drying time, better color retention, and more consistent quality compared to sun or air drying.

Q: Will the color and fragrance be preserved?
A: Yes, controlled low-temperature drying helps preserve the natural color, aroma, and medicinal properties of chrysanthemums.
