TY - JOUR T1 - The Economics of Multiple-Effect Evaporation for Production of Grape Juice Concentrate JF - American Journal of Enology and Viticulture JO - Am J Enol Vitic. SP - 80 LP - 85 DO - 10.5344/ajev.1963.14.2.80 VL - 14 IS - 2 AU - R. L. Nowlin Y1 - 1963/01/01 UR - http://www.ajevonline.org/content/14/2/80.abstract N2 - For a seasonal operation such as the grape industry has, a triple-effect evaporator system cannot be justified for the capacity ranges common in the industry. A double-effect installation, however, should prove economical in almost all large installations where the season may be extended. At 500 gph capacity there is a cost spread of 1/2ยข per gallon concentrate between a double-and a single-effect operation with an 80-day operation. This amounts to $2.50 per hour, 24 hours per day, for 80 days, or $4,800.00 for the season. Since amortization costs, interest, etc., have already been accounted for, this represents actual plant profit. ER -
