No sorry. I'm starting to have way too many fruits myself, and I'm trying to breed a kobold with enough strength to grip clumps of fruits to grind but it's a process. There's actually a little part of the cave wall near the fruit trees that spawns a mushroom so you don't have to go inside! Hope that helps.
Yeah, I've been having no luck with dealing with the fruits in one of my saves. I waited too late to start grinding them and trying to grind 3+ fruits at a time has a tendency to break the reagent scanners and blenders. I think there's nothing to be done but to wait for the dev to add a fix like making fruits despawn if not picked up by a certain amount of in-game time.
