Keeping this in our mind, we not only make high quality food processing equipment China customized special design microwave vacuum drying equipment, but also help the clients to figure out the optimum processing work flows, make amendments according to client's specific needs, training staffs for the user of our equipment Microwave Sterilizing Equipment and even more, because we believe that our users or clients' success is the foundation of ours.Vacuum Freeze Dryer China customized special design microwave vacuum drying equipment is an advanced Hi-Tech dehydration technology, China customized special design microwave vacuum drying equipment makes hydrous materials frozen in the low temperature status, then under the vacuum condition, it adopts thermal radiation method for heating, to sublimate ice to gas directly. After the moisture comes out, China customized special design microwave vacuum drying equipment uses ice-condenser (cold trap) and vacuum device to dehydrate the water content. Shandong Leader Machinery Co.,ltd. is a combined application technology based on multidisciplinary development, including refrigeration, heating, vacuum, biological, electrical and etc.
6-10kw High degree vacuum microwave drying equipment
What is Microwave?
Microwave is the frequency of 300 MHZ ~ 300 GHZ electromagnetic wave, it is short radio waves in a limited frequency band, the wavelength between 1 mm ~ 1 m electromagnetic wave, it is generally referred to as the decimeter wave, centimeter wave and millimeter wave. Microwave frequency is higher than general radio frequency, often also referred to as "ultra high frequency electromagnetic wave. As a kind of electromagnetic wave of microwave also have wave-particle duality. Basic properties of microwave usually appears as transmission, reflection and absorption three characteristics. For glass, plastic and porcelain, microwave is almost through without being absorbed. For water and food, etc. will absorb microwave and heating by itself. For metal stuff, it will bounce back the microwave.
Microwave drying principle:
Microwave drying is a new type of drying method. When drying, microwave converted into heat energy that can be applied directly to medium, because the microwave has penetrating performance inside and outside the media, heating at the same time, do not need to heat conduction, so very fast heating, the water content below 30% of food, can shorten the drying speed hundreds of times. Regardless of any shape objects, because the object of dielectric heating at the same time, both inside and outside material of inside and outside temperature difference is small, uniform heating, the drying quality greatly improved.
Microwave sterilizing principle:
1. The heating effect of the microwave energy: in a certain intensity under the action of microwave field, insects and bacteria in food experience by molecular polarization, absorption of microwave energy to heat up, making it the protein denaturation, lose their biological activity.Plays a role of quick heat sterilization microwave thermal effect mainly.
2. The microwave non-thermal effect: high frequency electric field makes the membrane potential, polar molecule structure change, make the protein and physiological active substances in microbial mutation, and loss of energy or death.In sterilization by conventional physical sterilization no special effect, is also one reason for killing bacteria.
3. The microwave sterilization, keeping fresh is the result of the combination of microwave thermal effect and non-thermal effect. Therefore, microwave sterilization temperature is lower than the conventional method, under normal circumstances, the conventional method of sterilization temperature to 120 ℃ to 130 ℃, time of about 1 hour, and microwave sterilization temperature to 60 ℃ to 70℃, only about 4-5mins, it also depends on the different products.
Vacuum freeze drying Microwave Sterilizing Equipment technology has widely application, such as for chemical products, biologics, health product, herbs, agricultural products ( meat, poulty, egg, sea food, vegetables and fruits and etc.) Shandong Leader Machinery Co.,ltd. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.
