WHAT WE DO
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.
- Energy Saving
- Environmental Protection
LABOAO focuses on the development, production and sales innovation of vacuum freeze-drying technology products. With a deep understanding of vacuum freeze drying technology, we have a management team composed of excellent professional managers and a technical team composed of senior refrigeration experts, senior vacuum experts, senior electronic control experts, and senior mechanical design experts. They are in product development , Promote and maintain a tacit cooperation, deeply understand the meaning of "customer centric", "service" runs through every detail of the company's operation and management, and win the trust and support of customers.

LEARN ABOUT FREEZE DRYING
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.
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.
At present, many companies are considering the use of freeze-drying technology for product production. Different companies have different characteristics and require different types of freeze-drying machines. At present, there are many manufacturers of freeze-drying machines in the world. How to choose the freeze-drying machine that suits the actual needs of the enterprise is a crucial issue. The following will list which parameters should be paid attention to when purchasing a freeze dryer:
