Plandai Biotech have an ultra-sonic extractor they tried to sell me on.
It’s claim to fame is that it can turn whole tomatoes into mush in moments. If left on a little longer it isomerizes up to 50% of the lycopene (that what makes ‘matoes red) into a more bioavailable form.
Means you can feed kids tomato mush to prevent blindness. Not a bad thing.
However, unless you kief first, turning your cannabis biomass to mush just makes the job harder, and why would anyone want their finely tuned cannabinoid profile randomly reorganized during extraction?
