Lyophilisation Machine

Advantages of lyophilisation machine:

There are various drying methods, such as sun drying, boil drying, spray drying and vacuum drying, etc., but common drying methods are usually carried out at temperatures above 0℃ or higher. The products obtained by drying generally have the problems of reduced volume and hard texture, most of the volatile components will be lost, some heat-sensitive substances will be denatured and inactivated, and some substances may even be oxidized. Therefore, the dried product has a great difference in properties compared with that before drying. A freeze dryer can avoid the above problems well.

Disadvantages of freeze dryers

As the saying goes, there is no perfect technology, and the main disadvantage of vacuum freeze-drying technology is the high cost. Because it requires vacuum and low temperature conditions, the freeze dryer needs to be equipped with a vacuum system and a low temperature system, so the investment cost and operating cost are relatively high.

The development of freeze dryers should pay attention to energy saving and comprehensive utilization of energy, such as adopting various combined heating methods, transplanting heat pump and heat pipe technology, developing solar energy resources, etc.; also develop the automatic control technology of freeze dryers to ensure optimal operating conditions. In addition, with the emphasis on environmental protection by human beings, improving the environmental protection measures of freeze dryers to reduce the leakage of dust and waste gas will also be the direction that needs in-depth research. In the face of various challenges, the freeze-drying industry can develop better only through innovation and development and efforts to improve.
