Application of shelf heating Freeze Dryer in environmental protection soil lyophilization
The application of shelf heating Freeze Dryer in environmental protection soil lyophilization, with the continuous development of society and economy, but the environmental pollution problem is becoming more and more serious.
Under the situation of soil pollution, whether it is to repair the contaminated soil or to protect the uncontaminated soil, soil monitoring has become the top priority. Traditional soil sample processing methods have always been air-dried or low-temperature dried. The disadvantages are low efficiency and long drying. It is not possible to dispose of multiple samples in a timely manner. With the development of vacuum freeze-drying technology, shelf heating Freeze Dryer has been widely used in environmental protection soil freeze-drying. Some environmental monitoring departments took the lead in adopting the shelf heating Freeze Dryer as a dry disposal device. So far, a complete soil monitoring sample pretreatment scheme has been formed. The soil sample pre-treatment scheme covers freeze-drying and locking of elements before soil sample detection, freeze-drying and locking of soil organic matter, and locking of soil original form to ensure the maintenance of soil samples before testing to ensure the authenticity and effectiveness of soil sample monitoring.
