Working Princple of Freeze Drying Machine
Under LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables condition, material is freeze dried via principle of sublimation. The moisture in the pre-frozen material is directly sublimed from solid state (ice) to gaseous state (vapor), without melting. Freeze dried products are formed to be sponginess, without shrinkage and excellent in rehydration, containing little water only. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.Features & Advantage
Advantages of Freeze Drying Equipment
1. Efficient in heating plates. The material of heating plates is aviation aluminum after being anodized on the surface, releasing over 100% heat from the product by radiation. This makes heat more uniform and complete.
2. Alternate vapor trap. Double trap is installed under the heating plates in drying chamber. Trap 1 condenses vapor to its maximum cpacity, then trap 2 starts to work. In the meantime, trap 1 begins to melt ice for another condensation cycle.
3. Continous de-icing. When the trap 2 begins to catch vapor, the trap 1 begins to melt ice on the coil during drying. After melting, the clean coil is ready for another condensation cycle.
4. Automatic control system. Advanced intelligent control system keeps the system running stably and reliably in a long time. Furthermore, simple operation can be much easier to handle.
Advantages of Freeze Dried Products
1. Nutrition basically remains. As drying is operated in low temperature and LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables condition, the nutrition is kept completely.
2. Form basically remains. The water of food is drained directly from solid to gas, so the structure doesn’t change.
3. Colour basically remains. As drying is operated in low temperature and LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables condition, the physical and chemical property of food changed little. There is also possibility of oxidation and enzyme, thus easy to keep original color.
4. Fragrance basically remains. Because the fragrant components in food largely exist in amorphous concentrated section during freezing, the fragrance can be kept when ice crystals are gasified.
5. The quality of product hardly losses. Because of the low rate of sublimating, the substance is basically in quiescent state. Thus the loss of product can be ignored.Freeze-dry Process

Shenyang Aerospace LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables Quick freezing Equip. Manuf. Co., Ltd was founded in 1985, a LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables enterprise incorporating the research, manufacturing, sales and services of food processing equipment and freezing technology. Freeze drying equipment and IQF freezing equipment are widely used around the world.
LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables Company closely cooperated with Atlas Company in Denmark, Harbin Commerce University, Zhejiang University and Northeastern University, etc., supporting over 1,000 food engineering projects both domestically and abroad.
It is one of the earliest, largest and most infLG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetablestial professional manufacturers in China. Our products have been exported to USA, Canada, Germany, Netherland, Singapore, Thailand, Malaysia, Indonesia, Korea, Myanmar, Chile, Nigeria etc. The company pays highly attention to food quick freezing, LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables freeze drying, LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables frying solution and pre-processing system.
Now LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables Company aims to give all of our customers best products and services.

Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.
microwave dryer is a new type of environmental protection drying method. When dry, LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables directly to the medium molecules converted into heat, because the LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.
microwave dryer advantages of equipment
1, microwave dryer, short, fast
Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.
2, LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables low temperature sterilization keep the nutrition and traditional flavor The LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
3 microwave dryer and LG200 microwave food lyophilizer industrial freeze dryer for fruits and vegetables save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
