=Chill-Room Bunkers.=--In chill-room bunkers there should be a brine system arranged to drip the brine over the pipes for use during the early hours of filling, since a double advantage can be gained by so doing. This is quite effective when intelligently operated. =Freezer and Storage Buildings.=--The use of freezer buildings have become of such consequence in larger packing plants for the storage of meats that it would seem opportune to introduce a description of a freezer storage building and to discuss the requirements necessary for it. [Illustration: FIG. 30.--CROSS SECTION COOLER, BUNKER “CURTAIN” SYSTEM.] _Growth._--The growth to include as it now does, in most instances, a produce merchandising business with its seasons of production and storage together with the necessity of providing low temperature storage space for storing delicately cured hams and bacon over seasons, make it almost a necessity to provide low temperature storage or seek it away from the premises, with the incident expense involved in transfer and return, storage charges, and the damage resultant from exposure. _Location._--A first consideration is the location of the building for operating advantages, which is a local matter, but involves shipping facilities by team and by car, convenience to the source of production, and power plant. Naturally the value of the commodity in storage, which at present prices, reaches a considerable amount, and the safety of the product becomes a matter of no small thought. _Permanence._--The permanence of a building for this purpose once constructed, and the likelihood of changes due to variation in business being small, together with the safety of its contents and a consequent low insurance rate, makes fire-proof cold storage buildings highly desirable. In these days of increasing insurance rates, buildings that are rated from twenty to thirty cents per thousand dollars--non-sprinkled--appeal to us. These rates are not uncommon. Such can be obtained on properly constructed buildings with adequate exposure protection. _Concrete or Steel Frames._--Fire-proof cold storage buildings can be of various styles of construction. The two types mostly used being, first, of steel frame with either cast iron or steel columns, girders and beams with tile or concrete in combination for floors, or secondly, reinforced concrete frame with concrete and tile in combination, or monolithic concrete floors.
