Product Description
What is Microwave drying?
Microwave is an electromagnetic wave whose frequency is between 300MHZ~300GHZ and wavelength is between 1mm ~1m. the characteristics of microwave usually shows penetration, reflection and absorption . For glass, plastic and porcelain, microwave will penetrate it without being absorbed. For water and food, it will absorb microwave and heating by itself. For metal material, it will reflect the microwave.
Microwave drying : Water molecule is polar molecule, it will change its polarity and friction motion caused by the effect of high speed change of high frequency electormagnetic field. Then the microwave electromagnetic filed energy can be converted into heat energy and achieve the purpose of drying. Due to the strong penetrability, microwave can heat up the material outside and inside simultaneously and evenly, so that won't appear the condition that the outsie dry but inside wet. The formation of body heat source state shortens the time of heat conduction and save a lot of drying time.
Microwave sterilization:Microwave sterilization temperature is from 70℃~105℃, period is from 90 seconds ~180 seconds. Microwave thermal effects can change the bacterial protein and make bacteria to die owing the loss of nutrients, reproduction and survival.Meanwhile, Microwave eletromagnetic field can make normal growth and stability of the genetic breeding of bacteria nucleic acid【RNA】 and deoxyribonucleic acid【DNA】 number of hydrogen bonds slack, breakage and recombination, thereby inducing genetic mutations, chromosomal aberratiuons and even rupture.
What is the main features of microwave Industrial fruit microwave dehydration sterilization machine durian dehydrator drying machine?
1.Low-temperature and high-efficiency: As is well known,If the pressure reduces, the boiling point of water will decrease.Under an atmospheric pressure(101.3kpa ),the boiling point of water is 100 ℃, if under the 0.073 atmospheric pressure(7.37kpa) the boiling point of water will decrease to 40 ℃. under the Industrial fruit microwave dehydration sterilization machine durian dehydrator condition, heating objects can evaporate the inside water without heating. When microwave Industrial fruit microwave dehydration sterilization machine durian dehydrator dries heat-sensitive substances, the drying rate is much higher than the conventional dry, the ratio is generally more than a dozen or even dozens.2.Heating evenly and thoroughly: the higher the moisture content is, the more microwave the products absorbed ,the larger energy the product generats . if the moisture content is lower, the condition is on the contray.Meanwhile, due to the inside and outside of the product is heated simultaneously, no inertia residued, no heat transfer loss, so the drying speed is rapaid.Microwave can penetrate the products directly, intensify water molecules and generate heat. the internal temperature is slightly higher than the external temperature, so that the temperature gradient can be avoided and eliminates the condition of outside dry but inside wet.
3.Control simply:owing the microwave power can be adjusted rapidly and has no inertial residue, combined with the PLC automatical control system, you can ajust and confirm the process parameter in time.
4.Improve quality:Drying products in a low-temperature, oxygen-free environment is more certainly to ensure products quality.
5.Keep the primary color:Owing the microwave drying time is short, it solved the problem of the conventional drying :such as the drying time long and the product color changed due to the moisture high. Especially for valuable medicinal herbs ,Chinese medicine extract and seafood ,it is a kind of ideal drying methods. Such as :cordyceps sinensis, ginseng, extractum ,sea cucumber, etc.
6.Energy conservation and environmental protection:compared with the conventional electrical drying methods, microwave drying can save power by 50%.The equipment adopts microwave radiative transfer energy, which is the whole heating of the medium, without the need of other heat transfer media, so that can avoid the defect of heat conduction slow in Industrial fruit microwave dehydration sterilization machine durian dehydrator conditions.Therefore, the speed is rapid, the efficiency is high, the drying cycle is greatly shortened, and the energy consumption is greatly reduced too. Owing there is no noise, no toxic gas and toxic liquid emissions, it is an environmental drying technology.
Summary: From above characteristics : drying evenly and thoroughly,energy conservation, emission reduction, improve product quality and yield, safety and healthy and various aspects ,you can see its significant economic and social benefits..
