Method of processing margarine or butter for squeeze packet containers

Abstract

Margarine or other foodstuff with similar physical properties is warmed to room temperature and placed in a mixing bowl (10). The margarine is blended by stirring with paddles (12). Then, the margarine is mixed until it has a substantially uniform viscosity by a recirculating pump (14), extrusion of the margarine from the recirculating pump through a screen (16), and continued stirring with the paddles. A 15 to 30 second burst of steam is applied into jacket (20) liquifying but not clarifying the margarine contiguous with the edge of the vessel. The recirculating pump draws the liquified margarine from the edge of the mixing bowl and pumps it into the top center of the margarine where it is blended into substantially unheated margarine. The process is repeated until the margarine attains a viscosity in the range of 16,000 to 18,000 centipoise. Once this viscosity range is reached, the margarine is pumped into a holding tank (26). A filling machine (30) draws the margarine from the holding tank and pumps metered volumes into heat sealed squeeze packets (60).
