The microwave drying and maturing equipment for soybeans can bake whole grains and mixed cereals in just a few minutes, ensuring even heat distribution. The roasted grains become easier to grind into powder with a rich aroma. Unprocessed soybeans carry strong beany odors, and adding unsterilized soybean flour to soy milk or other foods will introduce these unpleasant smells, directly compromising the original flavor of the products. The microwave sterilization and deodorization equipment for soybean flour developed by Longdia Machinery effectively removes these odors, improving product quality while providing sterilization functions. This ensures hygiene standards, higher added value, and superior product quality.

Applicable to soybean products, meat products, flowers, edible fungi, snacks, spices, puffed products, and canned food, meeting diverse processing needs.
Used for soybean milk raw material processing, removing beany odor to ensure the pure flavor of soybean milk and other beverages, enhancing product market competitiveness.
Leveraging advanced microwave technology, the Soybean Precision Microwave Roasting Dryer completes roasting and drying of whole grains in just a few minutes, with electromagnetic waves activating molecular friction inside materials for consistent heat distribution. Unlike traditional heat transfer methods that cause temperature inconsistencies, its automated conveyor belt and intelligent temperature control system ensure uniform heating throughout the entire processing cycle.
Equipped with professional microwave sterilization and deodorization technology, the device effectively decomposes odor-causing substances in soybeans, completely eliminating beany odor without damaging nutrients. It simultaneously achieves high-efficiency sterilization during processing, ensuring compliance with food hygiene standards and extending product shelf life.
Adopting low-temperature microwave roasting (lower than conventional maturation temperatures), the Soybean Precision Microwave Roasting Dryer retains the natural nutrients, taste, and beautiful color of soybeans. Roasted grains feature a crisp texture, easy grindability, and excellent rehydration performance, ideal for soybean flour and grain product production.
Crafted with high-quality materials and precision engineering, the Soybean Precision Microwave Roasting Dryer operates stably under harsh industrial environments (0~40℃, relative humidity ≤80%). Its transmission belt width (800mm, customizable) and propagation velocity (0.1-5m/min) are adjustable to meet diverse production demands, while simple operation and maintenance reduce downtime and operational costs.
With customizable feed/discharge port heights (50mm default) and outline dimensions, the device seamlessly integrates into existing production lines. It adheres to international food processing standards, with a working frequency of 2450±50HZ and microwave output power ranging from 20KW to 200KW, ensuring consistent performance across different models (LDY-20PW-4X to LDY-200PW-18X).
Low baking temperature, beautiful color, good retention of nutrients, good taste, beautiful color, microwave low temperature baking baking temperature is lower than the conventional baking maturation temperature belongs to low temperature baking.
Homogeneous Baking and Maturation: Equipped with intelligent temperature control and baking time management, this microwave-assisted system utilizes electromagnetic waves to activate molecular friction within soybeans and grains. Unlike traditional heat transfer methods that often cause temperature inconsistencies and uneven baking, our fully automated production line employs continuous conveyor belts for simultaneous processing of roasting, maturation, and temperature monitoring. The intelligent temperature control system ensures uniform thermal distribution throughout the entire baking cycle.
It has a certain puffed effect, crisp taste, easy to grind powder, good rehydration performance, microwave baking and heating quickly, and sterilization is accompanied during baking. The quality of roasted soybean and grain is easy to control, simple operation and simple maintenance.
The material is put into the feed port → automatically discharged to the conveyor belt → the material is transported into the microwave drying box → the material is dried and sterilized → the material is cooled out of the box → the material is stored and packaged.
