Top Rated Freeze Dryer For Flowers

The stability of the cooling system directly affects the quality of freeze-dried products

With the advantages of other drying methods, lyophilizer has been more and more favored by people. In addition to being widely used in the fields of medicine, biological products, food, blood products and active substances, its application scale and field are also expanding.

The refrigeration system of the top Rated Freeze Dryer For Flowers is the core system, its stability determines the quality of the lyophilized products, so the stable operation of the refrigeration system is very critical. The refrigeration system is mainly composed of the following components: Compressor, refrigerant, condenser, oil separator, filter drier, intercooler, depending on the liquid mirror, solenoid valve, hand valve (top), expansion valve, evaporator, plate exchanger, box after condensing coil), gas-liquid separator, gas filters, pressure gauges, pressure control relay, CPCE (energy regulator), relief valve, cooling pipe, etc.

Refrigeration system features:

1. The temperature range is wide. The shelf cooling in the drying oven is cooled from normal temperature to -40℃ ~ -55℃, and the condenser needs to be cooled to -50℃ ~ -70℃.

2. Severe load changes, the shelf should be pre-frozen, according to the different processing technology of the products sometimes need to be heated. Heat treatment of recooling. And after the end of pre-freezing, the compressor is switched to the condenser for rapid cooling. The drying load varies with the different products and the difference of the loading quantity, so that the load in the process of lyophilization changes daily.

3. In the later stage of lyophilization, that is, in the secondary drying stage, the moisture in the products is quite small. At this time, the load of the condenser decreases, and the compression is forced to run without load for a long time.

In order to ensure the stable operation of the cooling system of the lyophilization mechanism, it is necessary to check whether the pressure gauge and temperature gauge are operating within the range, listen to the operation of the equipment for noise, check whether the equipment is running or leaking, and do a good job of equipment maintenance in time. Now let's talk about how to properly maintain.

1. Only personnel with professional knowledge can carry out the maintenance or repair of the refrigeration system.

2. Electrical components have high voltage, so the power supply should be cut off first during maintenance or repair.

3. After the power is switched on, the power switch is in the state of being switched on. Even if there is no operating equipment, the compressor may start to recover refrigerant at any time.

4. The high temperature of the high pressure part is above 100℃ to prevent scald; the low temperature of the low pressure part is below -70℃ to prevent frostbite.

5. The refrigerant pollutes the atmosphere and cannot be discharged at will. When discharging refrigerant, please start from the high pressure part and ensure that the cooling water in the water condenser is in the flowing state to prevent water freezing and cracking.

6. Refrigerant filling and discharge should not be operated in closed environment or open fire to avoid asphyxiation and poisoning.

7. Refrigerant filling and discharge Wear personal protection and handle with care to avoid liquid refrigerant splashing into eyes or skin.

8. It is forbidden to weld or disassemble parts of the refrigeration system in the state of pressure.

Advantages

1.Preserve color and shape: Freeze-drying technology can preserve the natural color and shape of flowers, which is better than traditional drying methods.
2.Extend shelf life: The treated flowers can be stored for several years without deterioration, making them suitable for making permanent decorations.
3.Reduce maintenance: Freeze-dried flowers do not require special maintenance to maintain their beauty for a long time, and are not affected by humidity and temperature.

 

FAQ

Q:What is the principle of flower freeze dryer?

A:Firstly  freezing  the flowers quickly, turning the water into ice crystals. Then, in a vacuum environment, the ice crystals are directly sublimated into gas and discharged through low-temperature heating, thereby removing the water from the flowers. This process can maximize the preservation of the natural shape and color of the flowers.

 

Q:How long does it take to freeze dry flowers?

A:The freeze drying time of flowers depends on the type, size and water content of the flowers. Generally speaking, the whole process may take 24 to 72 hours. The model and operating parameters of the equipment will also affect the drying time.

 

Q:How long is the warranty period of your products?

A:We provide one year warranty.
