industrial ice cream maker

Ice Cream? (This is not a joke !!!)?
Thus, even if it seems completely absurd that need your honest answer. I need make homemade ice cream for 125 people. no electricity for an industrial giant ice maker not working. I heard that you can make ice cream in a bowl and place in a large container full of salt and ice, but do not know if this process of working with large quantities. someone can give me some ideas on how to accomplish this difficult task? thanks!
You need to have something like a 55-gallon drum containing the internal container and all of the salt. How in the world which is nearly freezing of the contents? Here is a recipe for Tin Can Ice Cream and make 3 cups. http://www.aces.edu/pubs/docs/E/EFNEP-0131/EFNEP-0131.pdf Obviously, there that increasing quantities. Good luck!
