Why to choose freeze dryer?
Do you hope to have an equipment to dry fresh food material without nutrition lost, and meanwhile preserves its original taste, flavor and color? Only freeze dryer can meet this requirement. Do you want to get the most healthy dried food with the lowest cost far away from those outrageously expensive pharmaceutical freeze-dryers? Our freeze dryer can make it.

1. The drying tank of vacuum freeze dryer is made of stainless steel (reinforced with carbon steel anti-rust). All the connectors inside the tank except the I-steel guide rail are made of stainless steel, and the metal hose connected with the heating plate is made of stainless steel, flange connection to prevent vibration. 2. In order to meet the needs of production, we provide one set of skip car and material tray for one set of equipment. The material tray is made of aluminum alloy, the skip car and the hanging rail are made of stainless steel SUS304, the skip car hanging rail is made of carbon steel, anti-rust treatment. 3. Refrigeration, heating, vacuum, electrical, rail transportation and defrosting systems are all controlled automatically Especially the rail transportation system adopts pneumatic control.

.png) | Rear type disposable water capture: The technology of making the frozen water-bearing material undergo ice sublimation (adsorption water evaporation) to escape from
the material as water vapor, and condense the water vapor with the water trap, so as to obtain the dry products |
.jpeg) | Lyophilized into the front section of the warehouse: In the sublimation drying process, the vacuum pressure in the drying chamber should be lower than the saturated vapor pressure corresponding to the eutectic point temperature of the material. |
| Lyophilized rear section of cold trap: Desorption drying is to remove the unfrozen part of water (called adsorption water) adsorbed on the capillary wall and polar gene of the material to ensure the good quality of lyophilized products. |
 | Freeze-dried skip truck tray: For the materials on the tray, the upper surface is the best, the lower surface is the second, and the center part is the worst. With the heating, the material has been dry layer (free water layer) from the upper and lower surface gradually to the central part of the advance. |
 | Freeze-drying with fluorine refrigeration system: Fluorine refrigeration unit is small in size, occupies less space, does not need to set up a separate machine room, greatly saving space, low noise unit, all valves are fully closed valve parts, safe operation. |
 | Germany Laibo vacuum pump group: 1. Oil-free vacuum pump-Because there is no oil lubrication in the vacuum chamber, the dust will not remain in the pump chamber, but with the gas discharged from the exhaust port outside the pump. 2. Oil-free compressed vacuum pump Because the gas is compressed in the pump, the power consumption is low. |
Instructions on food freeze dryer equipment:
1. Customize according to the planned production capacity, and use the incoming batch as a reference.
2. When the production capacity is customized, the configuration of the host used by the freeze-drying equipment is unchanged, and the volume of the product freeze-drying warehouse is changed.
3. The freeze dryer equipment is transported in the whole cabinet, and the foreign on-site installation service is suspended. When installing, you can find a local mechanical engineer for on-site installation. The specific content of the customized contract shall prevail.
4. Reference for the conventional capacity of food freeze-drying equipment: 50 square meters, 80 square meters, 100 square meters, 120 square meters.
5. The price of the freeze-drying equipment production line is subject to the price of the customized model.
Remarkable advantage of freeze-dried food:
1, Retain biological activity
To retain biological activity as much as possible, the material must be in low temperature environment, but on the contrary, drying needs heat involved. Heating will destroy biological activity and nutrition. Our solution is to get the liquid water in the material completely frozen to solid status. The water in the material is solid ice status during the whole heating processing till the material is completely dried. So, the biological activity is retained greatly.
2, No damage to the nutrition
Heating is no doubt the main reason of nutrition damage. By using our freeze dryer, heating processing occurs after material gets completely frozen to ice status. Thus, it typically retains 97% of the nutritional value.
3, Taste, color and appearance
Lyophilized by our freeze dryer, the material still tastes fresh, delicious as a snack, but a different try. The freeze dried material remains the same color, flavor and appearance as it was firstly harvested. And the volume of freeze dried material has no change, that is to say the appearance has no shrink or toughen. It is the real high quality preserved food.
4, Longer shelf-life
Freeze dried food material has a longer preservation time than frozen food, canned food and oven drying food. Having freeze dried food storage, you do not need to rack your brains what to eat and far away from pigmentum, additive, GMO and anti-season food material. Freeze-drying help us design a healthy lifestyle.
