Product Description
The industrial green tea microwave enzyme deactivating equipment applies high frequency 2450 MHz microwave energy directly to polar water molecules inside fresh green tea shoots and leaves. These molecules vibrate, rub and collide at an ultra high frequency of 2.45 billion times per second, rapidly converting electromagnetic energy into thermal energy to achieve fast, uniform inside out enzyme deactivation for green tea raw materials.
Different from conventional roller fixation and pan firing, microwaves deliver excellent penetrative volumetric heating, quickly raising the internal temperature of tea tissues. It effectively solves common pain points of traditional green tea fixation: uneven heating, incomplete passivation of polyphenol oxidase, red leaf edges, burnt leaves, inconsistent color and unstable batch quality of green tea.
During operation, freshly harvested green tea shoots are evenly spread on the food grade wear resistant conveyor belt and fed into the multi cascaded chamber microwave tunnel via variable frequency speed regulation. Microwaves penetrate tea leaf tissue and heat from inside out, rapidly deactivating oxidase to terminate enzymatic browning. The matched exhaust dehumidification system instantly removes water vapor, completing continuous integrated enzyme deactivation, preliminary dehydration and leaf shaping in one continuous production run.
The homogeneous microwave thermal field avoids local overheating and burnt odors. It protects chlorophyll, tea polyphenols and amino acids, locking the bright green color and fresh brisk taste characteristic of green tea, improving leaf integrity and stabilizing finished tea quality for large scale industrial production.
Main Advantages
Internal and External Synchronous Heating, Uniform Fixation Quality for Mass Production This industrial green tea microwave enzyme deactivating equipment adopts volumetric molecular heating rather than surface heat transfer. It heats tea leaves simultaneously from inside to outside, eliminating incomplete enzyme deactivation, reddening, local scorching and inconsistent fixation. Fixed green tea features uniform emerald color, intact leaf texture and stable quality, greatly increasing the qualified product rate in continuous mass production.
Fast Controllable Heating, Preserve Green Tea’s Bright Color & Fresh Taste The equipment realizes rapid enzyme deactivation under precisely controlled temperature, fully retaining chlorophyll, amino acids and natural aromatic compounds. It avoids the defects of long time high temperature roller processing such as burnt flavor and nutrient loss. It is ideal for bulk industrial production of premium and ordinary green tea requiring stable green color and brisk taste.
PLC Intelligent Adjustable Process, Adaptable for Different Green Tea Raw Materials Equipped with a PLC touch screen control system, microwave power, conveyor speed, cavity temperature and exhaust air volume can be adjusted steplessly. It adapts to tender shoots, mature fresh leaves and different grades of green tea raw materials. The modular integrated structure supports long time continuous industrial operation with convenient parameter tuning and routine maintenance.
High capacity Continuous Production, Clean Process & Stable Batch Consistency Multi stage microwave shielding ensures microwave leakage meets international safety standards. The fully automatic tunnel assembly line supports non stop 24 hour industrial production, greatly shortening fixation cycle compared with traditional roller machines. The closed processing environment reduces impurities and cross contamination. Processed green tea resists oxidative discoloration, suitable for large tea factories and export grade green tea manufacturing.
