Show Cold Storage for Fruit Three systems of cold storages are commonly used for fruit the ammonia ammo-nia system, carbonic acid gas and cat clura chloride eaya the New England Homestead. All are chemical atoi ages; but In a region where natural Ice can be obtained cheaply, the calcium cal-cium chloride gravity system seems to be much chesper than the "wo first, and equally good. Tbe ammonia system sys-tem haa to be pumped at a pressure of 200 pounds to 400 pounds to tbe square Inch. Hoth these require expensive duplicate machinery and high priced engineers night and day, while the cat clura chloride usee cheap machinery and ordinary help. O. H. Powell, for merly with the United States department depart-ment at Washington, aays the calcium chloride gravity aystcm la the best for northern localities. |
