Product Description
The fast‑food microwave heating tunnel adopts high‑frequency 2450 MHz microwave energy, directly acting on polar water molecules inside boxed fast food, ready‑to‑eat dishes, central‑kitchen fast‑food portions, chilled take‑away meals and sealed fast‑food trays. Water molecules vibrate, rub and collide at an ultra‑high frequency of 2.45 billion times per second, converting electromagnetic energy into thermal energy to realize continuous volumetric inside‑out reheating and pasteurization within the tunnel cavity.
Different from traditional steam tunnels and hot‑air ovens that rely on surface heat conduction, this continuous‑tunnel microwave equipment features strong penetration heating. It effectively solves typical industry drawbacks: surface over‑heating while food core remains cold, dried rice, mushy vegetables, sauce loss, large temperature deviation among individual fast‑food portions and unstable batch quality.
During operation, sealed fast‑food trays or lunch boxes are orderly placed onto food‑grade wear‑resistant conveyor belt, and continuously conveyed through multi‑segment cascaded microwave tunnel cavities with adjustable running speed. Microwaves penetrate packaging containers and heat rice, meat and vegetable ingredients simultaneously from inside to outside, rapidly raising core food temperature and suppressing pathogenic bacteria. Matched exhaust‑dehumidification system timely discharges water vapor and condensate inside tunnel, completing continuous integrated reheating, pasteurization and constant‑temperature treatment in one single pass.
Uniform microwave thermal field avoids local over‑cooking. It retains moisture, original flavor and nutritional components of fast‑food dishes, keeps rice soft and vegetable texture intact. It improves food safety for large‑volume group catering, cold‑chain distribution and mass fast‑food supply scenarios.
Main Advantages
Continuous Tunnel‑type Volumetric Heating, High‑throughput Uniform Reheating Adopts molecular volumetric heating instead of surface heat transfer. Fast‑food products are heated from inside to outside while passing through the tunnel. It eliminates cold core, scorched edges and uneven temperature. Processed fast‑food portions maintain consistent taste and temperature, supporting large‑volume continuous production and greatly raising finished‑product qualification rate for fast‑food factories and central kitchens.
Fast Short‑time Heating, Preserve Original Taste & Nutritional Value No pre‑heating required for startup. Short‑time rapid reheating reduces nutrition loss caused by long‑time thermal exposure. Rice stays soft, vegetables are not over‑cooked and sauce evaporation is minimized. Especially suitable for high‑volume chilled fast food, central‑kitchen portioned meals and group‑catering projects with strict taste and efficiency requirements.
PLC Intelligent Tunable Process, Flexible Adaptation for Diverse Fast‑food Packages Equipped with PLC touch‑screen control system; microwave power, conveyor speed, tunnel‑cavity temperature and exhaust air volume support stepless adjustment. It adapts to different sizes of sealed fast‑food trays, chilled or pre‑cooled ready‑to‑eat meals. Multiple processing recipes can be stored for quick switching. Modular multi‑cavity tunnel structure supports customized tunnel length and belt width, convenient for parameter debugging and daily maintenance.
Uninterrupted Automatic Production, Synchronous Pasteurization & Easy Line Integration Multi‑stage microwave suppressors installed at tunnel inlet and outlet ensure microwave leakage complies with international safety standards. The fully‑automatic tunnel assembly‑line enables non‑stop 24‑hour running with large hourly throughput. It can be seamlessly docked with upstream packaging and downstream boxing conveying lines. Microwave delivers synchronous pasteurization to inhibit mould and harmful microorganisms, enhancing food safety for campus canteens, high‑speed‑rail catering and export‑grade fast‑food products.
