Product Description
The pre made meal microwave heating machine adopts high frequency 2450 MHz microwave energy, directly acting on polar water molecules inside packaged pre cooked meals, chilled ready to eat food, boxed meals, central kitchen prepared dishes, frozen pre made dishes and portion packaged fast food products. 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 achieve fast volumetric inside out reheating and synchronous sterilization for packaged pre made meals.
Different from traditional steam ovens and hot air tunnel heating which rely on surface heat conduction, microwave delivers strong penetrating volumetric heating. It effectively solves common industry pain points of conventional processing: outer layer over heating while meal centre remains cold, dry rice, excessive loss of soup and sauce, uneven temperature distribution, nutrient loss and inconsistent quality across meal batches.
During operation, sealed packaged pre made meals are evenly placed on food grade wear resistant conveyor belt and continuously fed into multi cascaded microwave tunnel cavities with adjustable conveying speed. Microwaves penetrate the packaging and meal layers to heat food simultaneously from inside to outside, rapidly raising core temperature of pre made meals. Harmful microorganisms such as E. coli and mould are inhibited during heating. The matched exhaust dehumidification system timely discharges water vapor, completing continuous integrated reheating, thermal sterilization and constant temperature treatment in one production pass.
Homogeneous microwave thermal field reduces local over cooking. It well retains moisture, original flavour, texture and nutritional components of rice, meat and vegetables, minimizing soup evaporation. Finished pre made meals achieve uniform temperature and improved food safety performance for cold chain distribution and long term storage.
Main Advantages
Volumetric Inside‑out Heating, Uniform Reheating Effect for Packaged Meals
This equipment applies volumetric molecular heating instead of surface heat transfer. Pre‑made meals are heated simultaneously from inside to outside, eliminating cold centre, over‑heated edges, dry rice and uneven temperature. Temperature difference within each meal is kept small. Processed boxed meals maintain soft rice, intact vegetable texture and stable flavour, greatly improving finished‑product qualification rate for mass‑production of central‑kitchen pre‑made meals.
Fast Short‑time Heating, Preserve Original Taste & Nutrients
No pre‑heating required for start‑up. Short‑time rapid reheating avoids long‑time high‑temperature damage. It maximally retains moisture, vitamins and original flavour of pre‑made dishes, reduces soup loss. Especially suitable for chilled pre‑made meals, frozen ready‑to‑eat dishes and high‑value portion‑packaged food with strict requirements on taste retention.
PLC Intelligent Adjustable Process, Adaptable for Multiple Pre‑made Meal Types
Equipped with PLC touch‑screen control system; microwave power, conveyor speed, cavity temperature and exhaust air volume support stepless adjustment. It adapts to chilled, frozen, different‑weight packaged pre‑made meals, boxed group meals and central‑kitchen semi‑finished dishes. Multi‑segment parameter storage supports quick recipe switching. Modular integrated structure enables long‑time continuous running, convenient for parameter debugging and daily maintenance.
Continuous Automatic Production, Synchronous Sterilization & Extended Shelf‑life
Multi‑stage microwave suppressors at inlet and outlet ensure microwave leakage complies with international safety standards. Fully‑automatic tunnel assembly‑line realizes non‑stop continuous production, easy to connect with upstream packaging and downstream boxing lines. Microwave achieves synchronous sterilization to suppress mould and harmful bacteria. Treated pre‑made meals meet food‑safety requirements for cold‑chain logistics, retail sales and export‑grade ready‑to‑eat food products.
Equipment Composition
The pre made meal microwave heating machine is fully automatic tunnel type conveyor assembly line made of SUS304 food grade stainless steel modular design, complying with food processing hygiene standards. The complete unit consists of feeding station, material positioning section, multi cavity microwave heating tunnel, exhaust dehumidification system, online infrared temperature monitoring, microwave leakage suppression device, PLC intelligent control cabinet and automatic discharging unit. It is specially designed for large scale standardized continuous reheating and sterilization of various packaged pre made meals and boxed fast food products.
Application Fields
Custom developed for central kitchens, pre made meal factories, group meal catering enterprises, fast food processing plants and export oriented ready meal manufacturers. Widely used for continuous microwave reheating, thermal sterilization and post processing of packaged pre made meals. Treated meals maintain good texture, uniform temperature and high food safety level.
