The vacuum drying is a vertical freeze-drying device with a larger freeze-dried area, suitable for freeze-drying laboratory tests and small batch production. Freeze-drying equipment with partition heating function, large-screen LCD touch screen, programmable control and memory freeze-drying separator temperature curve and sample temperature curve. Using PID regulation, accurate temperature control, curve and data, it also provides users with more information about the freeze-drying process, and is equipped with a host computer communication interface that can be connected to a computer.
The vacuum drying uses a physics principle to freeze the moisture in the compressed air below the dew point to allow it to escape from the air. Confined to the freezing temperature of water, theoretically its dew point temperature can be close to 0 degrees. In practice, the dew point temperature of a good freeze dryer is generally around 5 degrees.
Phase maintenance of freeze dryers:
Before starting the machine, check whether the condenser on the back of the machine is clean to avoid poor heat dissipation.
Check whether the safety device is reliable before starting the machine.
Check whether the working pressure and operating current are normal after the machine runs for 10 to 20 minutes.
Run the compressed air for 10 to 20 minutes to check if there is any drainage in the automatic drain.
The machine should open the drain valve more than twice a week.
The manual drain valve of the machine platform must be drained twice a day or more.
When the ambient temperature is high, check if it exceeds 40°C. If it exceeds, please improve.
Use a dry, compressed air or copper brush every week to clean the back of the machine condenser more than once.
Every month, check whether the automatic drain valve has dirty plugs. If it is dirty, clean it.
Every three months need to check whether the cooling fan fan has a bad vibration phenomenon.
Check and tighten all screws, bolts, and various fixtures annually.
Check, clean, and tighten all electrical connections annually.
Freeze dryer application range:
Food industry: Freeze dryers are often used for drying fruits and vegetables, meat and poultry, aquatic products, condiments, convenience foods and specialty products. Therefore, freeze dryers are also known as food freeze dryers to maintain the original color, aroma, taste and shape of food. The purpose of the freshness is unchanged, and the rehydration is good, the finished product is easy to store and transport, the cost is reduced, and the storage period is prolonged.
Medicinal health: in the drying of royal jelly, ginseng, turtles, cockroaches, cockroaches and other nutraceuticals, vacuum freeze-drying process, better preserve the original nutritional value, and make people believe that the nutritional products are pure and natural.
Pharmaceutical industry: used for dehydration and preservation of Chinese and Western medicines such as serum, plasma, vaccines, enzymes, antibiotics, and hormones.
Biological research: Long-term preservation of blood, bacteria, arteries, bones, skin, cornea, nerve tissue and various organs using vacuum freeze-drying technology, only need to supply water to regenerate when using, still maintain its physical properties
