Used with a frame and an hydraulic jack (manual or electric) this piston allows to extract about 1 lb of cacao butter out of 3 lbs pounds of cacao liquor, depending on the beans. The piston was made for Mindo Chocolate. I have used it only 3 times with a 20 Tons jack and it works fine, and better still if you heat the piston.
I am selling because I have stopped using cacao butter in my chocolate. The whole item weight 19 Lbs.
