The vacuum freeze dryers & lyophilizer produced by LABOAO are widely used in the fields of medicine, biology, chemical industry, food and other industries. The advantage of vacuum freeze-dried items is to preserve the original color, fragrance and taste of the material to a greater extent, and to preserve the activity of the product to a greater extent. Heat-sensitive and easily oxidized materials retain heat-sensitive components and do not change after drying. The dehydration is thorough, the dry product is light in weight and the shape remains unchanged.

  • How Does the Freeze Dryer Freeze-Dry Liquid?

    How Does the Freeze Dryer Freeze-Dry Liquid?

    There are many drying methods, such as sun-drying, boil-drying, drying, spray drying and vacuum drying, etc., but common drying methods are usually carried out at a temperature above 0°C or higher. The dried products generally have the problems of reduced volume and hard texture. Most of the volatile components will be lost. Some heat-sensitive materials will be denatured and deactivated, and some materials may even be oxidized. Therefore, there is a big difference in the properties of the dried product compared to the one before drying.
  • Why Should The Samples Of The Lyophilizer Be Pre-frozen?

    Why Should The Samples Of The Lyophilizer Be Pre-frozen?

    First of all, understand the working principle of the freeze dryer, which is to freeze the water-containing substance at a low temperature to convert the water into ice, and then convert the ice into a vapor state under a higher vacuum, and sublimate it to remove the water and preserve the substance. the way. The so-called pre-freezing is the process of freezing products that contain a lot of water into solids.
