Henan microwave equipment network news: microwave equipment ( honeysuckle dryer ) can be used to dry honeysuckle, using the principle of microwave heating. The direction and size of microwave frequency change periodically with time from 300MHz to 300GMHz. The process of converting UHF electromagnetic wave into heat energy is the principle of microwave heating. Water is a substance that absorbs microwave strongly. Water molecule in material is a polar molecule. Under the action of microwave, its polar orientation changes with the change of external electromagnetic field. 915 MHz microwave can make water molecule move 1.83 billion times per second, resulting in molecule abrasion, collision, heating and expansion of material.
Therefore, the moisture in honeysuckle can be absorbed rapidly, so as to achieve the purpose of drying. The microwave honeysuckle dryer, in the drying process, will first kill the green, using the honeysuckle's own moisture to form a vapor environment, in addition to the shock of high-frequency microwave, after killing the green honeysuckle to maintain the original color, and in this process can lose part of the moisture, saving drying time and cost. And our microwave honeysuckle dryer can achieve germicidal effect in the drying of seeds at the same time, which is an advantage that previous drying methods can not compare. Nucleic acid (RNA) and deoxyribonucleic acid (DNA), which determine the normal growth and stable genetic reproduction of bacteria, are convoluted macromolecules closely linked by several hydrogen bonds. Microwave sterilization is the result of the combined action of microwave thermal effect and biological effect. The thermal effect of microwave on bacteria is to denaturate proteins and make bacteria lose nutrition, reproduction and survival conditions and die. The biological effect is that microwave electric field changes the potential distribution of cell membrane cross-section, affects the concentration of electrons and ions around cells, thus changing the permeability of cell membrane. Bacteria are malnourished, unable to metabolize normally, and the structure and function of bacteria are disordered. Growth was inhibited and death occurred.
A strong enough microwave field can lead to hydrogen bond relaxation, breakage and recombination, which can induce genetic mutation, chromosome aberration or even breakage. The honeysuckle dried by microwave drying equipment has uniform dryness and green color. It does not destroy and change the nutritional components completely. It can meet the hygienic standard of food QS certification. And the yield is high, basically 4 kilograms of fresh flowers can produce 1 kilogram of dried flowers. This microwave honeysuckle dryer can also be customized for customers, users according to their own investment conditions, productivity, site size, working hours to select the appropriate equipment.microwave honeysuckle dryer can also bake rose, mint, lavender, carnation, tea and other materials. The advent of microwave dryer has brought a qualitative leap to drying equipment, and will also make food hygiene and safety to a new level.
