METHOD AND APPARATUS FOR COOLING OF LIQUID FOODSTUFFS CONTAINED IN FLEXIBLE PACKAGES ABSTRACT An apparatus and method are disclosed for cooling a liquid foodstuff contained in a bouyant flexible package. The apparatus comprises a tank, a cooling liquid in said tank and a percolating means for producing turbulence within the cooling liquid. Preferably there is also supplied a means for chil- ling the cooling liquid. The percolating means is preferably a compressed gas which is introduced into the tank through a dispersion means which comprises either a perforated surface or perforated pipe. A process for cooling a liquid foodstuff contained in a bouyant flexible package is also disclosed which comprises placing the flexible package containing the liquid foodstuff into a tank containing a cool- ing liquid, percolating compressed gas into the cooling liquid thereby inducing turbulence which will cause mixing of the foodstuff within the flex- ible package insuring uniform cooling of the con- tents thereof and removing the package from the tank after it has remained in contact with the cooling liquid for a period of time sufficient to uniformly cool the foodstuff contained therein to a tempera- ture below 40°F (4°C). The process allows hot- filled, flexible packages containing liquid food- stuffs to be cooled to 40°F (4°C) within a 2 hour period thereby avoiding unacceptable bacterial growth within the food product.
