Disadvantages of Vacuum Drying


Disadvantages of vacuum drying The main disadvantage is that a vacuum system capable of pumping water vapor is required, which makes the equipment investment cost high and the operation cost high; the equipment production efficiency is low and the output is small. To overcome these shortcomings, many scientific and technological workers have made many efforts. At the same time, due to the many advantages of vacuum drying, some products do not use vacuum drying equipment.

Therefore, the development of vacuum drying equipment will be very promising.

There are many types of vacuum drying equipment, a wide range of applications, and a relatively rapid development. The advantage of vacuum drying is that the oxygen content is low when drying under low pressure, which can prevent the oxidative deterioration of the material to be dried, and can dry flammable and explosive dangerous goods; it can vaporize the moisture in the material at low temperature, and it is easy to dry heat-sensitive materials; Recovery of valuable and useful components in the dried material; can prevent the discharge of harmful substances in the dried material, and can become an environmentally friendly "green" drying.
