Packing house and cold storage construction; a general reference work on the planning, construction and equipment of modern American meat packing plants, with special reference to the requirements of the United States government, and a complete treatise on the design of cold storage plants, including refrigeration, insulation and cost data .. . affects not only the quality of the meat, but makesit slimy and unattractive in appearance. In order to provide a proper circulation of air, it isnecessary to build a refrigerating loft above the cooler,with an arrangement of ducts and openings which willfurnish a natural gravity circulation. The air must beremoved from below and passed over the cooling coilsbefore it again reaches the hanging room. This arrangement is illustrated in Figure 40. Thewarm air duct along the wall acts as a chimney and drawsthe warm air and vapors rising from the meat, up to theloft above, where it circulates among the cooling pipes andcondenses and parts with its moisture. The heavier cold PACKING HOUSE COOLERS 61 air, now dried and free from moisture, falls through thecold air duct on the other side of the room, thereby pro-ducing a natural gravity circulation. The arrangement of coolers and pipe lofts is fullyillustrated in the plans and sections of packing houseplants, shown in the preceding FIG. 40—SECTION SHOWING AIR CIRCULA^TIGN IN COOLER. Refrigerating Lofts Over Beef Coolers In Figure 41 is indicated the construction of a refrig-erating loft over beef and sheep coolers. The floor is sup-ported on 6x12-inch yellow pine joists, which also carrythe hangers for the beef rails. The 3x3-inch wood strip,laid over the joists, is cut out for the bolt-heads in order 62 PACKING HOUSE COOLERS to give room for tightening up the hanger bolts. The con-struction above consists of a beveled nailing strip, overwhich is laid an insulated floor or drip pan. The beveledstrip is put in to provide an 8-inch slope for the floor tothe drain outlets
