Dandelion Drying Case
Dandelion is a plant that is both medicinal and edible, rich in vitamins, minerals, and antioxidants. It is commonly used in the production of substitute tea, health products, and more. The traditional sun drying method is limited by weather conditions, and it takes a long time and is prone to oxidation and discoloration; Although high-temperature drying is fast, it can easily damage the active ingredients. To balance efficiency and quality, this case adopts a 50 ℃ low-temperature drying process combined with pre treatment for withering, which only takes 2 hours to complete the drying, suitable for household and small-scale processing needs.
- Customer requirements (the customer is a small-scale agricultural product processing workshop and hopes to achieve the following goals):
Efficient and energy-saving: Shorten drying time and reduce energy consumption costs.
Stable quality: retains the color, flavor, and nutritional components of dandelion.
Easy to operate: suitable for small-scale production without professional equipment.
Storage safety: The finished product has a moisture content of ≤ 10% and can be stored for a long time.
- Analysis of process advantages
① Pre processing for filming:
Steaming for 5 minutes effectively inhibits enzyme activity, prevents browning, and the finished product has a bright green color.
② Low temperature rapid drying:
Low temperature slow drying at 50 ℃, completed within 2 hours, with a volatile component retention rate of over 80% (increased by 10% -20% compared to sun drying). Drying with roots
Retain active substances such as inulin in the roots and stems to enhance the added value of the product.
- Application suggestions
Alternative tea: brewed directly or blended with honey and red dates to enhance the flavor.Deep processing raw materials: dried and ground into powder, used to make health products such as dandelion capsules and compressed candies.
This plan solves the contradiction between efficiency and quality in small-scale production with the characteristics of low energy consumption, short duration, and high quality control, and has promotional value. The same process can be applied to the processing of herbaceous plants such as mint and mulberry leaves. Jinlu Machinery is committed to creating significant economic value for customers and meeting their drying needs.
