We have mincers in the company I work for, but they might be too big for you. And to build one, that could cost you a fortune. Allone the vital parts like the orga, plates and the knife are very expensive. You could try and contact the food ( meat) industry, they might have an old machine standing arround, or try any auctions and so on. We scrapped one nice machine about two years ago, suitable for a (very) small business.
I have seen them in some Indian shops. Gonna get one myself. [Mincer I mean] Reeco
Hi I have a berley machine it uses a no.32 mincer like the one in the picture above which you can buy from fishing shops etc
Its powered by an electric motor with a reduction box
There are quite a few on trademe now and again
Skippies are no problem but if you do a lot of kys the skin clogs it up and you need to clean it out
I've made a burley mincer. 8horse motor, down through a six to one, then two to one, doing about 200 rpm at the drum. Makes about 20KG in 10 minutes. You'll lose your fingers if you drop them in. It works well. I can send you pictures if you like.my email is [email protected]
