Pineapples! Again. Such a nice food to eat but the task of removing the thick and somewhat irregularly shaped rind is tedious. It is a two step process, first is slicing off the peel as thin as possible. I said, slicing off the rind with minimal pulp waste as possible. Second is taking off every single eye remnants. I think this is optional for those who can tolerate its nasty feel in mouth. Eye removal is done by making a continuous V canal. It is spiral from up to bottom. Several of these have to be made to get rid of it all. It entails pulp waste, but, it is better that eating it with nasty eyes
Mechanization has different ways of doing things. First, pineapples are sorted according to size. Then a cylindrical cutter is pressed on top, removing the rind including all eyes. Second is done by spinning the fruit and rubbing it against a sharp blade. Both methods dump away a lot of pulp. That is case if peeling is done in selling stations. The likes of supermarkets and street vendors. The task is rather tedious so there are customers for pineapples peeled at point of sale.
Pineapple peels may still be process as vinegar or juice. Large scale companies do it. Can also be done by vendors provided that they collect and store the peels in hygienic manner
The other day. A street vendor is selling solely pineapples. Only one but very saleable item. His trick, peel every fruit for free. It watched how it was done. The rind was sliced off with a sharp knife, wasting minimal pulp and leaving the eyes behind. Then, he took a v-shaped knife and dug out all the eyes in spiral fashion. It was easier and way faster than how I do it. The trick can be applied to machinery too. Peel thinly then remove the eyes with V knife.
