In the cyclic preparation of a length of curds by draining a mixture of whey and curds in an upright column, formed by a permeable casing, the preparation cycle consists of at least three parts: a thickening phase and an extrusion phase from the column and a lateral discharge phase of the length of curds. The mixture is supplied to one end of the casing and a length of the thickened mass of curds is removed periodically at the other end of the casing. The whey/curds column inside the casing is moved forwards at slow speed in the longitudinal direction of the casing during the thickening phase of the preparation cycle, the thickening phase and the extrusion phase taking place at the same time. The discharge phase of the cycle takes place when the column is stationary, within a time span which is less than 20% of the thickening phase and extrusion phase.

Method for the cyclic preparation of a length of curds and installation

An apparatus for preparing a curd mass by draining a mixture of whey and curds in an upright column consists of a permeable sleeve or circular or rectangular cross-section, one or more sleeves being surrounded, with some clearance, by a tube monted on a worktable. The apparatus further comprises means at one end of the tube, above or under the worktable, for feeding the mixture of whey and curds and means at the other end of the sleeve, under or above the worktable, for receiving and discharging a drained and extruded curd mass. The free space between the sleeve or sleeves and the tube is subdivided into various compartments, lying one above the other, with the aid of sealing dividers. Each compartment is provided with inlet and outlet connections for whey or cleaning liquid. The sleeve or sleeves disposed inside the same tube forms or form a fixed assembly with the partitions and with said tube. The assembly thus formed is detachably fastened on the worktable, while the connections of the compartments are also provided with detachable couplings.
