Working Princple of Freeze Drying Machine
Under Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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 as sponginess, no shrinkage, rehydration excellent, very little water containing. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.

(Freeze drying equipment)
1. Efficiency of heating plates. The material of heating plates is aviation aluminum with anodized on the surface, over 100% heat release to the product by radiation, keeping heating uniformity completely.
2. Alternate vapor trap. Double vapor trap are installed under the heating plates in drying chamber. Trap 1 condenses water vapor to its maximum working cpacity, then trap 2 starts to condense. In the meantime,trap 1 begins to melt ice for another condensation cycle.
3. Continous de-icing. When the trap 2 begins to catch water vapor, the trap 1 begins to melt ice on the coil during the product being dried. After melting, the clean coil 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.
(Freeze dried products)
1. Nutrition basically remains unchanged. Drying is operated in low temperature and Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 conditions, so the nutrition is kept, particularly effective to heat sensitive materials.
2. Form basically remains unchanged. The water contained in food is drained directly from solid to gas, so the structure doesn’t change, and just forms space between ice crystals. .
3. Colour basically remains unchanged. As drying is operated in low temperature and Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 conditions, the physical and chemical properties of food changed little. There is also little possibility of oxidation and enzyme, thus easily to keep original color.
4. Fragrance basically remains unchanged. Because the fragrant components in food largely exist in amorphous concentrated section in the process of freezing, the fragrance can be kept when ice crystals are gasified.
5. The quality of solids hardly losses. Because of the low rate of sublimating water vapor, the substances are basically in quiescent state, thus the loss of solids quality can be ignored.

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, Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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, Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 directly to the medium molecules converted into heat, because the Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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 Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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, Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 low temperature sterilization keep the nutrition and traditional flavor The Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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 Hot microwave sale mini freeze dryer for sale laboratory lyophilizer LG0.2 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%.
