Here in California many large extractors are figuring out how to use liquid nitrogen (LIN) in bulk. It is colder and safer than the alternatives you all have mentioned. The problem is procurement, dealing with Airgas and Praxair is very complex. If you have any specific questions lingering about how to deal with industrial liquid and gas suppliers hit me up.
