Honeysuckle, as a medicinal plant, has been used in Asia for thousands of years and is widely used in family therapy, tea, and tinctures to treat various diseases. Fragrant flowers and buds, whether freshly baked from the garden or dried, can be used as food. Honeysuckle is prolific, and dried flowers can ensure that they do not contain chemical residues and are better preserved.

The traditional sun drying method involves spreading honeysuckle on a drying mat, with appropriate thickness. When the sunlight is strong, it should be thicker to prevent rapid drying; When the sunlight is weak, it should not be too thick to prevent the flowers from turning black. First sun dry to 80% before rolling to ensure quality. It is best to pick honeysuckle on the same day and air dry it on the same day. However, traditional sun drying methods are limited by weather conditions and can only be dried on sunny days, making it difficult to control temperature and drying levels. On the other hand, honeysuckle is prone to dust pollution, time-consuming and labor-intensive, and the quality of its output is not high.

With the gradual improvement of living standards, the demand for honeysuckle has increased, leading to a situation of supply shortage in the market. The quality produced by traditional drying methods is far from meeting market demand. The harvesting period of honeysuckle in the south is generally from mid to late April to early May, which is also the beginning of the rainy season. Therefore, traditional air drying cannot be used, and only drying equipment can be selected.

Previously, there were drying methods such as coal-fired drying and boiler drying, but these methods were uneven, energy consuming, requiring dedicated personnel to monitor, posing safety hazards, and polluting the environment. Nowadays, many businesses are drying honeysuckle using drying dehumidifiers.

During the drying process, temperature, humidity, and airflow circulation speed are the three main factors that affect the drying quality. The temperature inside the drying room rises, causing honeysuckle to evaporate a large amount of water and increasing indoor relative humidity. Generally, it is necessary to install intake windows and exhaust pipes for ventilation and dehumidification, which inevitably leads to the discharge of heat, wasting a large amount of heat energy and increasing production costs.

Drying and dehumidifying machine, referring to the Nicano principle, has both closed dehumidification and heating functions. Internal circulation closed drying, without the need for strong exhaust, utilizes high temperature to evaporate the water inside honeysuckle, and continuously discharges the water through the internal circulation dehumidification system, directly and quickly reducing the humidity in the drying room, achieving the goal of drying honeysuckle. Due to the absence of strong ventilation and dehumidification, the drying process reduces the loss of thermal energy and saves energy. During the drying process, the drying dehumidifier can set the drying mode and temperature and humidity parameters through the intelligent temperature and humidity control system, and dry in stages to better improve the drying quality of honeysuckle.

The compressor of a conventional dehumidifier has a temperature protection function and is generally used in environments between 5-38 ℃. The drying and dehumidification machine can achieve drying and dehumidification work within 65 ℃, efficiently ensuring the drying needs of honeysuckle.
