because I'm writing a script and I want the bad guy to die by falling into a grape crusher
Take the BUCHER Press because under 200 bar pressure the bad guy are pressed out hmm jammi juice
Wow, that would be a violent demise. If your villain perhaps deserves a more serene death, he could be overcome by carbon dioxide while punching down the cap of grape skins at the top of a fermentation tank. Did he survive? Was he rescued from the tank? Wait for the sequel...
Technically I don't think so. Grape crushers do not apply that much pressure. Cracking grape seeds gives the wine a bitter taste. Maybe he gets trapped and then drowns on the grape juice!!!
A grape crusher is called a grape crusher because it just happens to be crushing grapes. However, if a person falls in, it becomes a person crusher. And besides I've read worse plots in books thats for sure.
MOST grape crushers would probably kill you if you managed to fall into one. There are a few that use an air bag to gently press the grapes (made for extremely high-end wines), however, it is likely that you would suffocate if you fell into one of those. The hardest part would be to fall into the crusher, as the entrance is really quite small. One would have to first fall into the destemmer, (a long, open topped rectangular steel box with an auger running lengthwise through it that takes off the stems and partially crushes the grapes) although I am sure the destemmer would make short work of a human body.
