, and inspects sampling of nuts to estimate percentage that will be marketable from each delivery: selects random sample of nuts from each delivery, places sample in containers, and attaches identification tag to container. ) places nuts in drier to remove specified percentage of moisture. ) weighs nuts...
zinc coatings have a good resistance against solvents, but are not resistant against strong acids and bases. most zinc lining surface are porous and have a tendency to hold or trap previous cargoes making them somewhat difficult to clean to a high (wall wash) standard. caustic or caustic based soap mixtures...

associated with the release of odorous vapors. economic solutions for removing these pollutants typically entail use of activated carbon and/or chemical-based solid media in gas-phase adsorptive scrubber units. however, standard activated carbon solutions cannot effectively mitigate associated emission mixtures...
