Vacuum Royal Jelly Freeze Dryer

Vacuum Royal Jelly Freeze Dryer

Royal Jelly freeze dried powder is freeze dried by using fresh royal jelly, and then displayed under vacuum condition, the moisture inside product are sublimated from solid state to gas state. The freeze dry technique can better preserve the nutrients inside freeze dried powder, because mostly there are physical reactions taking place.

Fresh Royal Jelly, as a product, is not easy to preserve under room temperature, and has q relative complex procedure to use it. However, as the problems are solved, it is now one of the most popular product in the market.

Freeze dryers used for making Royal Jelly freeze dried powder undergoes the following process:

1.Filtration:

Add appropriate amount of distilled water, stir well, and then use 100 mesh nylon gauze to filter the impurities. Then display the filtered Royal Jelly into the freeze dryer's tray, with a thickness of about 8 – 10 millimeters. Do not seal for now, plays it in the freeze dryer's chamber.

2.Vacuum Low-temp Dry

Start freeze dryer, lower the temperature of vacuum freeze chamber to about 40℃, to freeze the royal jelly. Then control the vacuum degree at about 133 kPa, to contain the raw materials  temperature at about -25℃, and the condenser's temp is about -50℃, in this way, speeds up the discharge of steam. At the same time, the components of the freeze-drying chamber are heated and passed to the material tray to promote water sublimation. After drying in vacuum and low temperature for about 12 hours, the moisture in royal jelly has decreased to about 10%. At this time, the purpose of drying has been initially achieved, but it cannot be stored for a long time, so it must be continued to dry. At this time, the temperature of the drying chamber can be increased to 30℃, no more than 40℃, for 4 ~ 5 hours, so that the water quickly evaporates, so that the moisture content of royal jelly is reduced to about 2%, that is, the drying process is completed.
