Red koji is traditional Chinese medicine. As a traditional and unique import and export product, red koji pigment has been used for thousands of years in China.
Recent studies have found that in addition to being used as a food colorant, red koji pigment also possesses anti-inflammatory, antioxidant, bacteriostatic, cholesterol-lowering, anti-mutation, anti-tumor, and other biological activities. It can also be used to make solar cells and bio-printing and dyeing, etc., which has a very broad application prospect.
However, the current processing technology of red koji is rough. There are many impurities and fungi, so it cannot be applied to the purity standard of functional red koji at this stage, especially in the drying process, which is mostly exposed to direct drying in the air. To solve the problems existing in the drying technology, the utility model provides a microwave drying equipment — microwave red yeast rice drying equipment.
Microwave red yeast rice drying equipment is multi-used, can be used for the drying of red yeast rice, the sterilization of red yeast.
Machinery and equipment with automatic temperature control system, automatic microwave density control system, automatic correction system, automatic alarm system, variable frequency speed regulation system, material control system, data switching, programming system, selection of microwave source for the pattern, transformer oil immersion cooling method, ensure 24-hour uninterrupted working condition—red koji rice dryer assembly inline operation, simple operation, high output.
Principles of microwave red yeast rice drying equipment :
Microwaves are radio waves with frequencies ranging from 300 MHZ to 300 GHZ. Water molecules in the heated medium are polar molecules. Under the action of the fast-changing high-frequency magnetic field, its polarity orientation will change with the variation of the external electric field.
At this time, the field energy of the microwave field is transformed into the medium’s heat energy, which increases the material temperature and produces a series of physical and chemical processes, such as thermalization and expansion, to achieve the purpose of microwave heating and drying.
Microwave red yeast rice drying equipment features:
1. Rapid and efficient, a short time can achieve a large number of continuous production
2. When drying, it can remove bacteria and mildew to extend the storage time. Meanwhile, microwave also has a certain expansion function to make the material full, bright, and beautiful, improving the quality of the material.
3. The drying is balanced, complete bacteria removal, microwave dryer bacteria removal is carried out in the material at the same time, not easy to appear uneven situation.
4.Energy-saving and environmental protection, green environmental protection, more than 30% energy saving than other methods, no “three wastes” exhaust.
5. Advanced technology, simple operation, can achieve automated production technology.
6. The footprint is small, safe, and non-toxic, microwave red yeast rice drying machine size can be customized according to the specific production situation, material characteristics, and industrial plant size.
Red yeast rice microwave drying equipment is also called the microwave dryer to dry and sterilization. It is a microwave drying equipment used for drying food, medicinal materials, wood, building materials, cardboard, and other materials.
Compared with the traditional drying equipment, red yeast rice dryer has some advantages, such as uniform drying, thorough sterilization. Microwave drying sterilization in the material inside and outside simultaneously avoids the appearance of the uneven phenomenon, with fast drying speed, high efficiency, environmental protection, and energy-saving. It is new equipment in response to the low-carbon economy.
