Product Description
This tunnel conveyor starch microwave drying equipment is designed for food-grade native starch and modified starch dehydration. Wet starch filter cakes and solids separated from centrifuged starch slurry are difficult to process using traditional hot air drying. Conventional heating readily creates a hardened outer crust while moisture remains trapped deep inside the material. Uneven thermal exposure may also induce unintended gelatinization, damaging starch flowability and critical functional properties. This starch microwave drying equipment provides gentle, homogeneous dehydration tailored for starch feedstock.
Water molecules embedded within starch granules absorb microwave energy and produce frictional heat throughout the material bed. Wet starch is laid out in thin, consistent layers on food-grade conveyor belts before entering the microwave tunnel chamber. Vaporized moisture is rapidly drawn away through dehumidification ducts. Under standard operation, temperature is controlled beneath the gelatinization point of starch to maintain inherent powder attributes.

Core Strengths
Uniform volumetric heating inhibits surface crust development. Moisture dissipates evenly through the entire material layer, overcoming the dry shell and wet core defect common to hot air drying.
Accurate temperature regulation prevents accidental starch gelatinization, maintaining consistent whiteness, particle fineness and free-flowing powder performance required for downstream formulation.
Tunable operating parameters adapt to corn starch, cassava starch, potato starch and various modified starch grades with varying incoming moisture content. Quick-disassembly structure facilitates full cleaning when switching between different starch materials.
Dependable microwave shielding complies with food manufacturing safety standards. Continuous conveyor operation boosts batch processing capacity. Dehydrated starch is suitable for direct screening, packaging and blending into compound food ingredients.

Equipment Composition
The starch microwave dryer adopts a fully automatic tunnel type assembly line structure with food grade anti pollution modular design. It delivers stable operation, meets food sanitation requirements and allows easy maintenance. The complete set consists of multiple core functional systems including feeding, material spreading, microwave drying, exhaust dehumidification, intelligent temperature control and automatic discharging. It is well suited for large scale standardized dehydration and drying of various starch filter cakes and starch powder raw materials.
Key modules: cake feeding hopper, uniform spreading roller group, microwave drying cavities, moisture exhaust assembly, online temperature sensor and automatic discharge chute. This starch microwave drying equipment is widely deployed in starch manufacturing facilities, food raw material workshops and modified starch production lines.
Application Fields
The starch microwave dryer is custom developed for starch processing, food ingredient and modified starch industries. It is widely used for low temperature drying, dehydration, sterilization and mildew proof treatment of various starch materials. Processed starch shows uniform moisture and stable physicochemical properties. It serves starch processing plants, food ingredient manufacturers and starch export enterprises.
Drying of Native Starch:
Precision dehydration for corn starch, potato starch, cassava starch and wheat starch, reducing powder caking and keeping stable whiteness and viscosity.
