Large Freeze Dryer with 1500kg Capacity


Product origin :CHINA

Delivery time :Within 3 Months

Supply capacity :100 Sets

The most popular freeze dryer is LG125 model with 1500kg loading capacity per batch, Two sets of drying cabinets sharing one set of auxiliary equipment can save 30% energy during whole freeze drying process.
This vacuum freeze dryer adopts two alternate cold traps to reduce the drying time and increase loading capacity, and De-icing processing occurs during freeze drying period, it does not need separate time to defrost ice after freeze drying. 95% de-icing water comes from the sublimated product.

Advantages of Freeze Dried Food

1. Taste fresh                    

Freeze-dried foods, like frozen, retain virtually all their fresh-food taste and nutritional content. Freeze-drying removes the water, not the flavor.

2. Look fresh                    

Freeze-dried foods maintain their original shape and texture, unlike dehydrated foods, which shrink and shrivel due to high-temperature processing. Freeze-drying removes water under low temperatures which keeps intact the moisture channels and food fibers. Just add water, and in minutes every fresh food detail returns.

3. Weigh less than fresh 

Freeze-dried foods have 98% of their water removed. This reduces the food's weight by about 90%. Because of its light weight per volume of reconstituted food, freeze-dried products are popular and convenient for hikers. More dried food can be carried per the same weight of wet food, and remains in good condition for longer than wet food, which tends to spoil quickly. Hikers reconstitute the food with water available at point of use.

4. Stay fresh                    

 Freeze-dried foods can be stored at room temperature, without deterioration or spoilage. This is because freeze-drying and packaging remove both water and oxygen - the two primary causes of food deterioration.

Working Princple of Freeze Drying Machine

Under vacuum 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 20 years.

Freeze Dryer can be used to process nearly all kinds of food.

The LG series of freeze drying plant is designed for wide range of products such as instant coffee and tea, freeze dried fruit, vegetables, meat, seafood and prepared meals and so on.freeze drying equipment for sale

We adopt two alternate cold traps (vapour traps) for vacuum freeze dryers, and Its greatest strength is an alternating double cold traps with continuous automatic de-icing system.

Trays with product locate between heating plates, the cold trap I and cold trap II locate under the heating plates inside the drying chamber. When cold trap II is working for condensation of vapor, that comes from the product, and cold trap I is working for defrosting. Low temperature steam (15~25℃)comes from de-icing tank into cold trap I to defrost the ice on the tube, and defrost water goes back to de-icing tank and drained out. Condensation and defrost function change alternately, and controlled by PLC automatically .

So, this kind construction has limitless on product loading capacity, it has much more advantage than other kinds of freeze dryers.

Advantages of LG series 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. Double Side Radiation Heating Method 

There is a certain distance between the tray and the heating plate, avoiding the direct contact, the product is heated evenly. If the temperature of the heating plates gets higher, this heating method can protect the product from getting burnt.

3. Compact Design 

Double cold traps are built in the drying chamber, this leads to the compact structure, no need extra place. Compared to other suppliers, the unique design of de-icing tank requires less space, instead of a large water pool.

4. Saving Water 

De-icing tank under the drying chamber, which is connected to the vapor trap. The water used to melt the ice comes from the drying material. So this helps save a huge amount of water from wasting.

5. Stable Efficiency 

Alternate vapor trap, continuous de-icing. Double vapor trap are installed under the heating plates in drying chamber. During the drying process, the two cold traps work continuously and alternately.When Cold Trap I is condensing, Cold Trap II is de-icing at the same time, and after some time, they change to each other’s state. The Cold Trap II begins to catch water vapor, the Cold Trap I begins to melt ice on the coil, after melting, the clean coil ready for another condensation cycle. There's no extra time needed for separate ice melting, and that helps to increase the output to a certain extent. Due to CDI (continuous de-icing) technology, the ice layer is usually thin for melting, the surface of the coil tube of the cold trap is always at a lower temperature, the capture efficiency remains relatively high all through the whole drying processing, which ensures high quality of products.

6. Sanitary Guarantee 

De-icing system works under a negative pressure condition, the vapor used for melting the ice is from the drying material, which avoid bacterial infections, and it’s much more clean and sanitary.

7. 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, and to save manual resource. And the we can design fully automatic display screen according to your requirements. For process different products, different control curves can be preset in advance, and the equipment will be running accurately according to the preset curve.
