Product Description
The herbal flower tea microwave enzyme deactivating equipment adopts high frequency 2450 MHz microwave energy, which directly acts on polar water molecules inside fresh flower tea raw materials, including chrysanthemum, honeysuckle, rose, osmanthus, dandelion, lotus leaf, mulberry leaf and mixed herbal flower buds and fresh leaves. Water molecules vibrate, rub and collide at an ultra high frequency of 2.45 billion times per second, converting electromagnetic energy into heat energy to realize rapid, volumetric inside out enzyme deactivation for delicate flower tea materials.
Different from traditional steam blanching and hot air fixation, microwave features strong penetrating volumetric heating. It effectively solves common industry drawbacks in conventional flower tea processing: uneven heating, incomplete enzyme passivation, petal browning, bud cracking, aroma loss, destruction of floral active substances and inconsistent batch quality.
In operation, sorted fresh flower and herbal raw materials are evenly laid on food grade wear resistant conveyor belt and continuously fed into multi section cascaded microwave tunnel cavity with adjustable conveying speed. Microwaves penetrate flower buds and leaf tissues, rapidly raising material temperature to passivate polyphenol oxidase and peroxidase, terminating enzymatic browning reaction. The matched exhaust dehumidification system timely discharges water vapor, completing continuous integrated enzyme deactivation, preliminary dehydration and shaping in one pass.
Uniform microwave thermal field avoids local over heating, burnt petals and stewed odor. It well preserves natural pigment, floral aroma, flavonoids and other active ingredients of herbal flower tea, maintaining complete bud shape, bright natural color and improving finished product stability and storage performance.
Main Advantages
1. Internal external Synchronous Heating, Uniform Fixation for Delicate Flower Materials
This equipment applies volumetric molecular heating instead of surface heat conduction. It heats petals, buds and leaf tissues simultaneously from inside to outside, eliminating incomplete enzyme deactivation, partial browning, petal scorching and uneven fixation. Treated herbal flower tea keeps intact bud appearance, uniform color and stable quality, greatly raising finished product qualification rate for mass production.
2. Fast Mild Heating, Preserve Floral Color, Fragrance & Active Substances
Precise temperature controllable rapid enzyme deactivation avoids long time high temperature damage. It maximally retains natural flower pigments, volatile aroma components and flavonoid active ingredients, preventing petal darkening and fragrance volatilization. Especially suitable for high grade edible flowers and sensitive herbal flower tea raw materials with strict requirements on color and fragrance retention.
3. PLC Intelligent Adjustable Process, Wide Compatibility for Various Flower Tea Varieties
Equipped with PLC touch screen control system, microwave power, conveyor speed, cavity temperature and exhaust volume support stepless adjustment. It adapts to different raw materials: tight flower buds, fragile petals, fresh herb leaves and mixed compound flower tea materials. Modular integrated structure supports long time continuous running, convenient for parameter debugging and daily maintenance.
4. Continuous Automatic Production, Synchronous Sterilization & Extended Shelf life
Multi stage microwave shielding ensures microwave leakage complies with international safety standards. Fully automatic tunnel assembly line realizes non stop continuous production, shortening processing cycle greatly versus traditional steam fixation. Closed processing environment reduces impurity contamination. Microwave achieves synchronous sterilization to inhibit mould and harmful microbes. Finished herbal flower tea resists oxidative discoloration and mildew, meeting requirements for domestic retail and export grade flower tea products.
