402 CORK INSULATION (b) Control of the humidity of the constant temperature room should be effected by suitable means, tests having demonstrated that a consider- able increase in the percentage of ice melting is effected by increasing the percentage of relative humidity in a constant temperature room from a low to a high point. (c) The mixture of ice and salt should be carefully regulated on the basis of weight. (d) The salt should be of standard specifications. (e) The ice used should be only hard, "black" ice, and should be crushed to uniform size. The finer the ice is crushed and the more salt used, the lower, within limits, will be the resultant temperature. (f) Ice and salt should be mixed thoroughly in suitable mixing box located outside the test room, and packed in the ice cream cabinet during a fixed period, at the same hour, every other day (48-hour icing), no ice and salt to be put on top of cans and brine to be drained off cabinet before each re-icing. (g) The ice cream to be used for test purposes should be a product of rigid specifications, because different mixtures and flavors require different temperatures to keep them in satisfactory condition, and the volume of ice cream in the cabinet should be a fixed quantity. (h) Special long-bulb thermometers should be used in ice cream cabi- nets, of such length as to obtain average temperature readings for the total depth of the ice cream and for the empty can of each cabinet. (i) Four days preliminary operation should be allowed to establish a temperature equilibrium in the walls of the cabinet before the test proper should be started, and the test should then continue for 30 more days. Tests performed under standardized conditions thus sug- gested, values for such standards to be fixed upon a practical basis for test purposes and a basis most nearly conforming to the practices of the ice cream industry, should be comparable, as to ice consumption, cabinet air temperature, ice cream temperature, and condition of the ice cream throughout the test. An electric ice cream cabinet may be tested in much the same fashion, the electric power consumption by the cabinet machine, instead of the ice consumption, being comparable with results of other electric cabinet tests.
CHAPTER XVIII. THE REFRIGERATED SODA FOUNTAIN 163.—Automatic Operation of an Intricate Unit Made Pos- sible with <strong>Cork</strong>board Insulation.—Soda fountain design has kept well abreast of all modern trends and developments in automatic carbonation, mechanical refrigeration, scientific insulation, pure food preservation, efficient operation, and rapid dispensation of popular delectation. And as a result the "fountain" is popular. Few of its patrons probably realize, however, that the modern soda fountain is an intricate and delicate assembly of beautiful store fixture, refrigeration plant, cold storage, chemical plant, and food and drink dispenser. Five different temperature zones must be automatically established and accurately maintained ; and all in a space often less than a dozen feet long and a quarter as high and wide! The modern soda fountain deserves admiration ; its successful operation is made possible by permanently efficient corkboard <strong>insulation</strong>, scientifically adjusted to the service desired. For it is one thing to produce refrigeration, and another thing to conserve it and apply it to good purpose. When a quarter-score temperatures must be maintained and controlled within such narrow confines as twenty cubic feet, the cold storage problem takes on a new interest and importance in- deed. <strong>Cork</strong>board <strong>insulation</strong>, properly utilized, permits of the most delicate and accurate operation of the most modern soda fountain, just as it has been of so much use and assistance wherever temperatures below that of the atmosphere are arti- ficially produced, efficiently maintained and advantageously utilized. 164.—Extracts from Manufacturers' Specifications* for •Descriptions are those of the manufacturer, and arc to be accepted only for what they may prove to be worth. 403
