CHECKING Lye is used to check the skins of prunes and grapes, so that their drying may be facilitated. Lye-dip- ping vats or lye-peel- ing machines of the types described on page 5 are used. The iruit is immersed in the hot lye solution long enough to break the skin by many minute fissures or "checks/' but not long enough to loosen it. The concentra- tion and temperature of the lye bath, as well as the duration of treatment, are similar to those for lye-peeling. SUBDIVIDING Three considera- tions affect the choice of the form in which materials are prepared for dehydration: (1) The desire of the consumer for a product in the form to which he has been accustomed, (2) the necessity for the manufacturer to subdivide the product to facilitate drying, and (3) the desire of the manufacturer to make a product of distinctive appearance. Most fruits are sliced, cubed, halved, or left whole. Usually vegetables are sliced, cubed, shredded, or chipped. The cutting is done by hand or by some one of the numerous ma- chines on the market. Some of the machines consist essentially of. Fig. 1.—Conveyor-belt mechanical lye-spray peeler and washer.
