Rose microwave drying equipment is widely suitable for drying roses.

Traditional rose drying methods commonly use natural air drying. This method is not only limited by weather conditions, but the color of the dried roses cannot be maintained in their original state. At the same time, in order to achieve the corresponding dryness, water loss is severe, and it takes 5 pounds of fresh flowers to dry 1 pound of dried flowers. Later on, hot air was used again, which avoided the influence of weather conditions but consumed a lot of energy. The key was that the dried products had extremely poor color and could not meet the requirements. Later, steam sterilization equipment was introduced before hot air drying, which solved the above problems. However, due to the high temperature and humidity in the steam sterilization process, although the enzyme activity was passivated and the color was improved, the nutrients of roses were greatly lost, and the effective ingredients were destroyed. At the same time, the moisture content of roses was increased during the steam sterilization process, which increased the drying cost in the subsequent drying process.

Using microwave equipment to dry roses can be used in one machine for both withering and drying. Microwave sterilization utilizes the moisture content of the material itself to create a steam environment. With the addition of high-frequency microwave oscillation, the sterilization effect is good, and the material color is bright. At the same time, some moisture is lost during the sterilization process, saving drying costs. After finishing the withering, the finished product is dried once by microwave drying. The dried flowers have uniform dryness, a green color, and do not damage or change the nutritional composition of the material. At the same time, they have sterilization function. The bacterial content of roses dried by microwave drying can fully meet the hygiene standards required by food QS certification. According to our actual calculations, microwave drying 4.6 pounds of fresh flowers can produce 1 pound of dried flowers, with a drying rate 8% higher than air drying.

The characteristics and mechanism of microwave drying are different from general drying techniques, and can be summarized as follows:

1) The drying layer in the microwave drying process first forms inside the material, and then expands outward from the inner layer. The reason is that the material is heated both inside and outside under microwave conditions, with the internal temperature higher than the external temperature. Water vapor is discharged from the inner surface, and a dry layer is formed inside the material first; Conventional heating can easily form a dry hard shell on the outside of the material, which not only affects the quality and appearance of the material, but also reduces the drying speed. Microwave drying fundamentally avoids the occurrence of the above situations.

2) Anti moth, anti mold, and extended shelf life. Microwave drying of wood can penetrate the interior of the wood and quickly kill parasitic insect eggs in the wood, achieving the effect of preventing moth and mold, and extending the shelf life

3) Microwave drying is energy-saving. Using far-infrared and steam energy for wood drying has an energy utilization rate of less than 50%, while using microwave as energy can achieve a utilization rate of over 75%, reducing energy consumption by more than 25% compared to far-infrared and steam drying.
