FIG. 65.—SECTION THROUGH TANK HOUSE.
Separation of Press Room.
—If the business is large the owner is fully justified in extending the parting wall through and dividing the press room. This arrangement requires the double investment in presses, cloths and all equipment, but gives the advantage that the pressings can be collected from edible tankage and used for edible purposes, provided always that the equipment is kept in proper shape. Whereas, if the parting wall is not extended through the press room, the oils are considered contaminated and are usable only for inedible purposes.
FIG. 66.—LITTLE NECK RENDERING TANK.
The [section] shown indicates that type of house where the press room is single, and the house above the press floor is divided.
FIG. 67.—TANK HOUSE, SHOWING NESTING OF TANKS.
Tank House Hazards.
—The tank house, from the nature of the business being hazardous, is best to be of fire-proof construction. Tanks constructed as shown in [Fig. 66], with the little neck head can be nested four in a bay and be made fully accessible on all floors.
