(4)Abrasive peelers This type of peeler has been used for many years in all branches of the vegetable processing industry. The earlier models were the'rumblerbatch- type, which cannot be considered seriously for a dehydration factory, owing to the limited throughput and the fact that the abrasive action is too severe and far too much weight is lost The new concept is to run the abrasive rollers longitudinally in a circular cage, fitted around a centre auger. This roll cage mixes and turns the vegetables to expose all surfaces, whilst the abrasive rolls also rotate at adjustable speeds to control the applied abrasiveness. Thus, control is applied on the severity of the abrasion by instant adjustment of the roll speed, and total exposure time is governed by the auger speed. The abrasive rolls on these machines can be exchanged for brushes when handling thin skinned or delicate vegetables It is almost inevitable that, when abrasive peelers are used for potatoes, a considerable quantity of free starch will be released from the peeling plant, and this again can produce an effluent disposal problem. Invariably, this effluent has to be settled out in tanks before the waste peeler water can be finally discharged It is not intended, in the foregoing summary, to denigrate or recommend any particular peeling system, as there will be many local factors and circumstances to be taken into account by the dehydrator when he is equipping his factory but the pros and cons for each system are based on the experience of the author in several differing locations.
