The loading capacity of LG50 freeze dryer is 600-750kg/batch for fresh product.

Advantages of Freeze Dried Food

1. Freeze-drying retains the nutritional value of the fresh product, as well as its fresh flavour and colour

Freeze-drying is akin to keeping the food in a state of suspended animation and so once rehydrated the food is as fresh and nutritious as it was the moment it was frozen. Dehydrating and canning involves the heating of food to temperatures which can impair its nutritional value by breaking down the vitamin and mineral content (vitamins A and C, thiamine, riboflavin and niacin). The taste can also be affected and heat can denature and break food fibres which change the texture.

2. Freeze-dried foods can be stored for the longest time-Good shelf life

Most dehydrated products, like dried fruits, vegetables, powders and TVP (soy protein), have a shelf life of about 15-20 years. Dehydrated items like honey, salt, sugar, hard wheats and oats have a 30-year shelf life - sometimes longer. Freeze-dried fruits, vegetables, just-add-water meals and real meats have a longer average shelf life of approximately 25 years. Freeze-dried food can be stored at a wide range of temperatures without the food or packaging being affected - the food remains fresh for many years.

3. Freeze-drying significantly reduces the food weight

Lyophilisation removes about 95-98% of a food's water content and so the weight of that food is reduced by as much as 90%. For people having to carry their own food for days or months at a time this is a huge benefit. Freeze-dried foods weigh a lot less than dehydrated foods, important for most of our customers who take part in long-haul endurance events where food weight and package size are crucial planning factors.

4. Freeze-drying is faster to prepare

Dehydrated foods require cooking. Many times, they also require some type of seasoning. This means that you need to spend time boiling the product in hot water and letting it cook, which can take anywhere from 15 minutes to 4 hours! With freeze-dried foods you just need to add water – hot or cold will do (up to 5-8 minutes usually), although it might take a bit longer using cold At the end of a long day, or during a precious few minutes' lunch break, no one wants to be kept waiting for their hard-earned rations!

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 a long time.

Middle Freeze Dryer LG50 with 600kg Capacity

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

We adopt double alternate cold traps for vacuum freeze dryers, and its working principle of freeze dryer with double alternate cold traps.

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.
