Abstract Apparatus for and method of pressing, draining and preparing cheese curd for curing. The apparatus and method are particularly adapted for forming large sized blocks of cheese. Cheese curd is placed in a form for pressing and draining. Blades, in the form of elongated wedges and having slots in their faces are disposed in the curd to uniformly drain the curd while it is being pressed. The blades are removed and the curd is subjected to further conditioning and packaged for curing in containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A method for manufacturing cheese from curd in particulate form comprising the steps of filling the curd into a container, locating a perforated V-shaped blade having spaced side walls in the curd, opening the curd by means of the blade a maximum distance of two inches, rotating the container about an axis generally in the plane of the blade, applying pressure to the curd while the blade is in the curd, draining the curd through the blade, and removing the blade with minimum disturbance of the curd so as to permit knitting of the curd to provide a cheese block of uniform texture.
Claim 2
Independent Claim
103 words
A method for manufacturing cheese from curd in particulate form comprising the steps of filling the curd into a container, locating a perforated V-shaped blade having spaced side walls in the curd, opening the curd by means of the blade a maximum distance of two inches, rotating the container about an axis generally in the plane of the blade, applying pressure to the curd while the blade is in the curd, draining the curd through the blade, and removing the blade with minimum disturbance of the curd so as to permit knitting of the curd to provide a cheese block of uniform texture.
Claim 3
Dependent Claim
15 words
A method in accordance with claim 1 including removing the blade in a vertical direction.
Claim 4
Dependent Claim
29 words
A method in accordance with claim 1 wherein the pressure applied to the curd while the blade is disposed therein is at least about 2 pounds per square inch.
Claim 5
Dependent Claim
19 words
A method in accordance with claim 1 including locating the V-shaped blade throughout a cross section of the container.
Claim 6
Dependent Claim
28 words
A method in accordance with claim 1 including providing elongated perforations in the blade, the elongated perforations extending in the direction of movement of the blade during removal.
Claim 7
Dependent Claim
19 words
A method in accordance with claim 1 including as additional steps pressing the curd after removal of the blade.
Claim 8
Dependent Claim
50 words
A method in accordance with claim 3 comprising the additional steps of pressing the curd after removal of the blade under a pressure of at least about 1/4 pound per square inch and vacuuming the curd while it is under a pressure of at least 1/4 pound per square inch.
