ABSTRACT:
A method of pressing and draining whey from cheese curd particles in manufacturing large sized blocks of cheese. Cheese curd is placed into a pressing container mold which has a removable internal draining means having dimple-like projections maintaining a space between the plates of the screen. In one embodiment of the invention, pressure is applied in a vertical direction on the curd particles uniformly draining the whey. The drain means is extracted, and a second application of pressure closes remaining interstitial voids. In a second embodiment of the invention, a first application of pressure is applied to the curd particles in two separate directions at the same time. A spreading spade is inserted between substantially vertical parallel foraminous plates thereby moving these plates further apart exerting a relatively horizontal force on the curd particles and, in conjunction, a press plate pushes down on the curd particles exerting a relatively vertical force on the curd particles. As a result, the whey is uniformly drained and the curd particles are substantially fused. The internal draining means is then extracted and a second application of pressure substantially closes interstitial voids remaining from the first application of pressure. A flexible plastic liner covers the curd particles and the container is closed. The container is subjected to a vacuum chamber whereby the curd is further compressed causing free whey to run out and removing air bubbles, whereby the flexible plastic liner is sealed to the curd particles. The pressing container mold is then ready for storage or shipping.
