Abstract
Abstract In the formation of cheese in which the separation of the curd and the serum and the molding of the curd are carried out under the action of gravity in a perforated upright tube, the gravitational action is combined with evacuation of the space surrounding the perforated tube to aspirate the serum and increase the relative density of the curd with respect to the serum, thereby speeding up the separation and improving the molding process.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir being spaced from said envelope and the bottom of said reservoir being connected to the top of said envelope, the bottom of said tube being provided with portioning means for separating the sedimented curd into equal-volume bodies of cheese.
Claim 2
Independent Claim
178 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir being spaced from said envelope and the bottom of said reservoir being connected to the top of said envelope, the bottom of said tube being provided with portioning means for separating the sedimented curd into equal-volume bodies of cheese.
Claim 3
Independent Claim
172 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir surrounding said envelope and communicating therewith at the upper portion of said envelope and said reservoir, said tube being provided with portioning means for separating the sedimented curd into equal-volume bodies of cheese.
Claim 4
Independent Claim
172 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir surrounding said envelope and communicating therewith at the upper portion of said envelope and said reservoir, said tube being provided with portioning means for separating the sedimented curd into equal-volume bodies of cheese.
Claim 5
Independent Claim
168 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir surrounding said envelope and communicating therewith at the top of the envelope and reservoir, said envelope having a movable portion receiving said tube and replaceably mounted in said reservoir.
Claim 6
Independent Claim
168 words
An apparatus for the production of cheese, comprising: at least one upright perforated tube adapted to receive a mixture of curd and whey and to permit the sedimentation of the curd in the whey within said perforated tube; a nonperforated elongated upright envelope spacedly surrounding said tube over the entire length thereof and hermetically sealed to enable evacuation of the space between said tube and said envelope; a reservoir of a size sufficient to collect said whey communicating with said space and adapted to receive liquid from said space; means for draining liquid from said reservoir; and a suction pump connected to an upper portion of said reservoir whereby evacuation of said reservoir separates whey from said envelope into said reservoir and increases the relative density of the curd with respect to the whey in said tube, said reservoir surrounding said envelope and communicating therewith at the top of the envelope and reservoir, said envelope having a movable portion receiving said tube and replaceably mounted in said reservoir.
