Product Description
This industrial tunnel conveyor microwave sanitizing system is a specialized microwave sterilization equipment built for flour-derived food raw materials and semi-finished grain products. Flour powder, noodle intermediates and pastry bases are susceptible to microbial proliferation during storage, while conventional thermal sterilization often causes unwanted starch gelatinization and permanent texture deterioration. This industrial microwave sanitizer adopts dielectric volumetric heating technology to deliver mild microbial control, catering to diversified flour-based feedstock in grain and pastry production lines.
Microwave energy penetrates loose flour matrices and noodle strips, stimulating polar water molecules to produce internal dielectric heat uniformly across the whole material bed. Powdery flour materials and strip-shaped noodle semi-products are evenly laid on food-grade wear-resistant conveyor belts and transported into multi-cavity microwave sterilization cavities. Accurate closed-loop thermal management suppresses mould, yeast and pathogenic bacteria hidden inside flour food. The supporting vapour exhaust and dehumidification unit promptly removes water vapour generated during microwave sanitization, realizing continuous inline microwave sterilization and avoiding excessive thermal input that triggers starch gelatinization.

Core Strengths
Dielectric internal volumetric heating completes thorough microbial deactivation throughout flour-based food layers. It avoids bulk starch gelatinization induced by overheating and retains the native physical traits and edible quality of flour-derived raw materials.
Low-intensity microwave sanitization conditions lower the risk of flour agglomeration. Post-treatment powder maintains outstanding flowability, and noodle semi-finished goods keep stable strip structure without deformation.
Intelligent PLC control system supports independent tuning of microwave power and conveyor speed. It adapts to powdery flour, semi-processed noodles and other flour products with different paving thickness and initial moisture. All material-contact components use food-safe materials to meet strict hygiene standards of grain food processing workshops.
Multi-layer microwave shielding cabins comply with global industrial safety norms. Uninterrupted tunnel automatic operation boosts throughput of bulk microwave sanitization. Flour-based raw materials after microwave treatment satisfy microbial safety requirements for downstream deep processing and grain commodity export.
