China's vacuum freeze-drying technology has achieved better development
In recent years, the technological development of the domestic vacuum freeze-dryer industry has always been behind the world level. With the continuous advancement of various technologies and rising investment in R&D and innovation, technological development will undoubtedly require more attention. However, China’s core technology fields are heavily dependent on imports, which has led to the vacuum freeze-dryer industry always following other countries, and it is unable to achieve overtaking.
Vacuum freeze dryer is a high-tech product integrating electronics, vacuum science, mechanics, thermodynamics, program control and other disciplines. It is the seven advantages of material microwave vacuum freeze-drying equipment in the drying process. A new technology and new process have been developed based on the analysis of theoretical changes, internal and external heat and mass exchange, and the in-depth study of the moisture migration process under vacuum freezing conditions.
Experts said that in exploring the new development path for drying technology, comprehensive consideration must be given to energy efficiency, environmental protection, and product quality in order to achieve comprehensive, coordinated, and sustainable development. To implement the development strategy of high efficiency and green drying, we must first take the path of resource-saving development, and change the single extensive drying into combination and intelligent drying. It is necessary not only to fundamentally transform the drying process, but also to carry out comprehensive and multi-level energy-saving technological transformations and vigorously develop drying technologies that use renewable energy and industrial waste heat.
Vacuum freeze dryer still needs to improve technical innovation
Insiders pointed out that domestic companies have accelerated the study of vacuum freeze-drying technology, which has reduced energy consumption to a certain extent, reduced pollution, brought more benefits and values ​​to the society, and made it necessary to achieve green production and low-carbon production. Contributions. At this stage, however, the vacuum freeze dryer revolution in China has not yet been successful. Vacuum freeze-drying equipment manufacturers generally have low innovation capability. Poor enterprises that can introduce new technologies and new products with independent intellectual property rights have led to slow development of drying technology. Knowledge achievements have not been effectively translated into actual productivity. At present, the R&D and innovation of technologies in the field of drying equipment mainly rely on universities and research institutes. Due to the disconnection of companies, it is difficult to effectively turn knowledge achievements into productivity.
It can thus be seen that relevant companies should carry out comprehensive and multi-level energy-saving technological transformations and vigorously develop drying technologies that apply renewable energy and industrial waste heat. However, domestic companies have accelerated the study of vacuum freeze-drying technology and are gradually building up the advantages of domestically produced equipment, and have basically achieved a leading position in the domestic market. Vacuum freeze-drying equipment will become the mainstream of market demand, the domestic industry must significantly improve the technical level, improve drying efficiency, reduce energy consumption, and contribute their own strength to achieve green production.
