PILI peels citrus fruits (oranges, lemons, Grapefruits, Bitter oranges) and other similar fruits. The machine doesn’t ruin the peel and cuts it in four equal pieces, without the two hard parts of their poles. The rest of the fruit is not cut by the knives and in this way the pulp is not attacked by bacteria and fungi, to be used for juice and marmalade. The cutting & peeling system is tuned automatically in accordance with the kind and size of citrus. PILI machines work with pneumatic operation system, taking orders by electric or electronic computer.
