Low-temperature preservation ensures material value: Utilizing vacuum low-temperature drying technology with adjustable temperatures (30-60℃°C), this method effectively prevents nutrient loss, component decomposition, and color deterioration caused by high heat. Particularly suitable for heat-sensitive and easily oxidized materials packaged in valve-sealed pouches, including food additives, pharmaceutical intermediates, and specialty powders.
Vacuum Environment for Enhanced Dehydration and Contamination Prevention: The equipment operates in a high-vacuum environment that lowers the boiling point of materials' moisture content, accelerating evaporation rates. This achieves 30%-50% higher efficiency compared to traditional drying methods. The vacuum barrier also prevents material exposure to external contaminants, effectively reducing risks of oxidation and mold growth while maintaining product purity.
Compatible with valve pockets, no need for secondary material pouring: The packaging is designed with a dedicated shelf and sealing structure. Materials can be directly loaded into the equipment with valve pockets without bag removal or material pouring, reducing material loss and dust pollution, lowering labor costs, and compatible with standard valve pocket specifications such as 25kg and 50kg.
Smart Temperature Control with Safe and Convenient Operation: Equipped with a PLC intelligent control system, it allows precise setting of parameters such as temperature, vacuum level, and drying time, automatically completing the drying process. The equipment features safety devices including over-temperature alarms and vacuum leak protection. The inner chamber is made of 304 stainless steel, which is corrosion-resistant and easy to clean, meeting food-grade and pharmaceutical-grade production standards.
Energy saving and high efficiency, reducing operating costs: the design of high efficiency insulation layer reduces heat loss; the vacuum system and heating system are optimized to reduce energy consumption per unit material by more than 20% compared with traditional hot air drying equipment, which can significantly save enterprise energy costs in long-term operation.

The Grain Microwave Dryer adopts internal heating technology, where microwave energy directly penetrates materials to drive high-speed movement of internal water molecules, realizing overall uniform heating without heat conduction loss. Its drying time is only 1/10 to 1/2 of traditional hot air drying, greatly improving production efficiency. Compared with conventional drying equipment, it saves 30%-50% of energy, significantly reducing enterprise operating costs.
With low-temperature rapid drying technology, the equipment effectively avoids the destruction of heat-sensitive nutrients such as vitamins and proteins caused by long-term high-temperature treatment. It maintains the original color, aroma, taste, and shape of grains, while forming a porous structure that enhances water rehydration. Additionally, the synchronous sterilization and insecticide function kills 99.9% of pathogenic bacteria like E. coli and mold, as well as eggs and larvae, extending the shelf life of products without chemical residues.
Equipped with a PLC and touch screen intelligent control system, the Grain Microwave Dryer enables precise setting and control of drying temperature, time, and power, ensuring consistent processing quality. It realizes automated continuous production from feeding to discharging, minimizing manual intervention. Multiple anti-microwave leakage designs ensure the leakage amount is far below national safety standards, and the whole process has no "three wastes" discharge, meeting environmental protection requirements.
The Grain Microwave Dryer is widely used in grain and nut processing industry, suitable for drying wheat, rice, corn, peanuts, walnuts, and other grains and nuts. It also plays an important role in fruit and vegetable processing, meat and aquatic products processing, seasoning and spice industry, and tea and beverage industry, providing efficient drying solutions for various agricultural products that need dehydration and sterilization.
Beyond agricultural processing, this equipment is applied in pharmaceutical, wood, and chemical product processing fields. It can be used for drying and sterilizing pharmaceutical raw materials, wood products, and chemical intermediates, meeting the diversified drying needs of different industries.
