1. High-efficiency and fast drying
Microwaves directly act on the internal moisture of scented tea to achieve rapid heating, and it only takes a few minutes to kill enzyme activity, greatly improving production efficiency.
Microwave penetrating heating heats the material inside and outside at the same time, and the drying speed is 3-5 times faster than the traditional method.
2. Uniform heating to maintain quality
Microwave energy has strong penetrating power and can heat the inside and outside simultaneously, avoiding the "outside burnt and inside wet" phenomenon in traditional drying, ensuring that the color, aroma and nutrients of scented tea are evenly retained.
Precisely control microwave power and time to prevent petals from over-drying or discoloration. For example, honeysuckle tea can maintain bright color and natural flavor.
3. Sterilization and insecticide to extend shelf life
The combination of microwave thermal effect and non-thermal effect can quickly kill bacteria, mold and insect eggs, extend the shelf life of scented tea, and does not require chemical additives, safe and residue-free.
4. Energy saving and environmental protection
Microwave heating does not require preheating, has high energy utilization rate, and can save 30%-50% energy compared to traditional hot air drying.
There is no exhaust gas or wastewater discharge during operation, which meets the green production standards.
5. Improve the retention rate of effective ingredients
Rapid inactivation of enzyme activity can prevent oxidation reactions, retain the natural pigments of scented tea (such as the ruddy color of rose tea), aromatic substances and active ingredients (such as the medicinal ingredients of honeysuckle).
Microwave drying can also promote cell wall breaking and increase the precipitation rate of effective ingredients during brewing.
6. Intelligence and convenient operation
The equipment supports automatic control (such as conveyor belt laying and power adjustment), and only 1-2 people are needed to complete the whole process operation, reducing labor intensity.
Summary
Microwave drying technology comprehensively optimizes the processing efficiency and quality of scented tea through a fast and uniform heating mechanism, combined with sterilization, energy saving and other characteristics, while meeting the needs of modern production for environmental protection and intelligence.
