Is there any that uses low-temperature crushing?
Thread Content
I am trying to work with a plant similar to celery, whose active ingredient is a substance related to chalcones; the concentration of this active substance drops significantly eight hours after harvesting, and the main factors affecting this are oxygen and temperature. Therefore, low-temperature drying and crushing technology is desired. I heard that there is a technique that can rapidly cool plants, then crush them directly, and subsequently remove the water by heating and creating a vacuum to obtain a dry powder. I would appreciate it if the experts here could give me some advice. Thank you.
It’s not simple – you need to soak celery in liquid nitrogen to freeze it into ice pops, and then crush them once they’re frozen

It’s not extraction; it’s direct crushing. Crushing itself is no problem at the moment, but the energy consumption for dehydration is too high – freezing dehydration technology is being used instead
