Rule 32.9.508 - STORAGE OF FINISHED PRODUCT IN FREEZER(1) Plastic cream or frozen cream intended for storage must be placed in quick freezer rooms immediately after packaging, for rapid and complete freezing within 24 hours. The packages must be piled or spaced in such a manner that air can freely circulate between and around the packages. The rooms must be maintained at -10° F. or lower and be equipped to provide sufficient high-velocity air circulation for rapid freezing. After the products have been completely frozen, they may be transferred to a freezer storage room for continued storage.(2) The freezer storage room must be maintained at a temperature of 0° F. or lower. Adequate air circulation is desirable. Butter intended to be held more than 30 days must be placed in a freezer room as soon as possible after packaging. If not frozen before being placed in the freezer, the packages must be spaced in such a manner as to permit rapid freezing and repeated if necessary, at a later time.Secs. 81-2-102, 81-22-102 MCA; IMP, Secs. 81-2-102, 81-22-102 MCA;
