to the best of my knowledge the news have misconstrued what happened, the machine that failed was a test high pressure unit developed by a company called Elmhurst research, and has no relation with the industrial units utilized to do things like guacamole, juices, dips etc. As matter of fact the person who died in the accident was the CEO itself.
It is very likely that this unit may not have had enough safety systems such as the “leak before burst” needed for this type of units. I have been involved in HPP systems for over 15 years. And the industrial units are indeed safe to operate.
I know that Hormel has used it extensively since 2005. I'm familiar with both the testing company and The deceased. It takes time for all the details to be released. Due to all the liability that's involved, everyone is staying tight lipped at this point.
That's correct fixbear, to date Hormel is the largest user of this technology. https://www.youtube.com/watch?v=zZvNRkvoHTI here there are some experiments Elmhusrt Reseach used to do. It does require some balls to be video taping a machine doing fatigue test using ultra high pressure with no protection.
