General :: Automatic Clearing Cache And Changes To Files And System For Tablet Shared To Public

I'm looking for a method or an application for android tablet, which allows me to quickly reset the device deleting any data (from the Internet cache, and the cache to the photos of the various programs such as facebook, twitter etc ...) and that does not allow any modification of the operating system. I need this solution because I have a restaurant and I want to put a tablet on each table for guests to make him see the menu (full of photos and videos), surf the internet and play with the kids.

is there an app that allows this? or is there a quick way to do this, such as a multiaccount management ? I remember, for example, that for windows there are applications that completely erase any unauthorized modification, files and cache, at the time you restart the operating system.
