W i n e s & V i n e s J U LY 2 0 1 4 49 CIP tanks save water, clean better T he University of California, Davis, recently installed 14 clean- in-place (CiP) tanks with 500-gallon capacities that dramati- cally reduce sanitation water usage at their LeeD Platinum- certified winery. North american wineries could pursue this CiP technology—as have many businesses in the food, brewing and dairy sector—to slash water consumption. "This technology has been in the dairy industry for 60 years, the pharmaceutical industry for about 25 years, and brewing for 10-15 years," Dr. David Block, chair of the UC Davis Department of Viticulture & enology, said in explaining the rationale behind purchasing the tanks for the university's Teaching and research Winery. "it has not been largely adapted by the wine industry yet, aside from use in some packaging facilities and a very small number of fermentation facilities. "a CiP system is a fixed-in-place, centrally located system that prepares all cleaning solutions and distributes them to the equipment that needs to be cleaned in the right concentration, for the right time, and at the right temperature and flow rate. The solutions are then returned to CiP system to be recycled back to the equipment being cleaned, held for the next cleaning (if they are clean enough, for instance, the last rinse of a tank may make an excellent first rinse for the next tank) or discarded. "other industries use CiP technology because it gives better and reproducible cleaning; it is safer for workers, and it uses less water, chemistry and personnel time. in addition to saving water with the CiP system, we will send the spent CiP solutions over to the Jackson Sustainable Winery Building to filter them and recover the water and chemistry for repeated use. in this way, we hope to minimize water use and bring the ratio down to 1 volume of water per volume of wine or lower." A.C. The teaching winery at UC Davis uses 14 clean-in-place tanks.
