Golden Chrysanthemum Drying Case

1、 Project Background

As a high-value medicinal and edible crop, the golden chrysanthemum requires extremely high drying technology. Traditional coal or firewood drying methods suffer from uneven temperature control and sulfide pollution, leading to discoloration (browning rate>15%) and loss of active ingredients in chrysanthemums. Jiangxi Liu Zonghuang Chrysanthemum Planting Base has introduced intelligent electric heating and drying rooms to achieve modern processing with precise temperature control, zero emissions, and high yield.

2、 Technical solution

①Core equipment configuration

Far infrared electric heating system: 36kW modular ceramic heating element, PID temperature control ± 1 ℃

Multi layer tray drying room: 304 stainless steel tray, movable trolley

Intelligent humidity control system: real-time monitoring of moisture content, automatic adjustment of dehumidification frequency

②Process flow

Fresh flower sorting (moisture content 75-80%) → placed on shelves → segmented drying (55 ℃ → 65 ℃ → 50 ℃) → cooling and shaping → packaging (final moisture content ≤ 12%)

3、 Advantages of electric heating technology

The temperature control of the electric heating drying room is ± 1 ℃, with precise stage regulation. The product qualification rate is ≥ 95%, and the flower shape is intact and golden. The energy consumption cost is ¥ 0.8/kg for fresh flowers (grain electricity), which is environmentally friendly, reliable, zero emission, and meets organic certification.

4、 Key benefit data

①quality improvement

The retention rate of chrysanthemum glycoside has increased by 22% (third-party testing report), the first grade product rate has increased from 60% to 88%, and the selling price has increased by 30%

②Energy saving and cost reduction

By utilizing a combination of photovoltaics and valley electricity for power supply, comprehensive energy consumption is reduced by 40%, and maintenance costs are only 1/5 of coal-fired equipment (without boiler cleaning requirements)

③Policy benefits

Approved for Jiangxi Province’s agricultural product processing electricity substitution subsidy (￥ 0.15/kWh), selected as the “Ganpo Craftsmanship” organic agricultural product demonstration base

5、 Industry promotion value

High value-added crops: suitable for drying flowers that are sensitive to color and flavor, such as chrysanthemums and roses

Rural Revitalization Project: Matching Rural Power Grid Transformation to Address the Pain Points of Clean Processing in Remote Areas

Smart Agriculture Integration: Can be connected to the Internet of Things platform to achieve cloud based management of drying curves
