To assist egg breakers to select effective apparatus and to arrange their plants to handle liquid egg in a sanitary manner and with maximum economy of space and labor is the purpose of this bulletin. The essentials for successful egg breaking are sanitary quarters, excellent lighting, proper ventilation, well-designed apparatus, facilities for quick freezing of liquid egg, and, of course, trained operatives. The thoroughly modern plant must provide a chill room for the eggs in the shell, a chilled candling room, a refrigerated breaking room in which the egg contents are removed from the shell, a room in which to wash and sterilize apparatus used in breaking, and a sharp freezer for the quick freezing of the liquid egg and its storage. Econ- omy in handling eggs demands that proper space be allotted to the several departments, and that each be so located with reference to the others that unnecessary walking and trucking are avoided. The egg-breaking room and that for cleansing the apparatus are of pe- culiar importance. On these subjects this bulletin gives conclu- sions based upon a special study of frozen and dried eggs. It rec- ommends certain improvements in the distribution of space, and discusses new equipment devised to meet special'requirements of the industry. To a
