If he’s asking if you freeze dry, he’s gonna have a hell of a time hunting down the gear if he calls vendors asking about a flash freezer…
@Matt889 flash freezers are a thing, and making hash rosin from fresh frozen biomass is generally considered the way to go…but you don’t need a flash freezer to flash freeze.
…and you will probably want a freeze dryer long before you scale to the point of justifying a blast freezer.
