An apparatus for matting and milling cheese curd. A mixture of curds and whey is fed onto a porous endless belt of a first conveyor to form a layer of curds with the whey draining through the belt. As the leading end of the curd layer reaches the downstream end of the first conveyor, the speed of the first conveyor is reduced to match the speed of a second conveyor which is located at a slightly lower level than the first conveyor, so that the curd layer is transferred from the first conveyor to the second conveyor while the conveyors are operating at the same speed. A third conveyor is positioned beneath the second conveyor and operates at the same speed as the second conveyor. As the curd layer is transferred to the third conveyor it is inverted. A fourth conveyor is positioned beneath the downstream end of the third conveyor and the curd layer is transferred to the fourth conveyor while the fourth conveyor is operating at the same speed as the third conveyor. The curd layer is then discharged from the fourth conveyor to a curd mill which acts to cut the curd layer into cube-like chunks.
In a continuous cheese matting apparatus first conveyor means including a first porous conveying member and having an upstream end and a downstream end, feed means for feeding separate quantities of curds and whey to the upstream end of said first conveyor means to form a plurality of curd layers that are spaced along the length of said first conveyor means, each curd layer having a leading end and a trailing end, said whey draining through said first porous conveying member, second conveyor means including a second porous conveying member and having an upstream end disposed at a lower level than the downstream end of said first conveyor means and disposed to receive each curd layer from the downstream end of said first conveyor means, means responsive to the leading end of each curd layer approaching the downstream end of said first conveyor means for varying the speed of said first conveyor means to approximate the speed of said second conveyor means so that each curd layer is transferred from said first conveyor means to said second conveyor means while said first conveyor means and said second conveyor means are operating at approximately the same speed.
In a continuous cheese matting apparatus, first conveyor means including a first porous conveying member and having an upstream end and a downstream end, first variable speed drive means for driving said first conveyor means, feed means for feeding separate quantities of curds and whey to the upstream end of said first conveyor means to form a plurality of curd layers that are spaced along the length of said first conveyor member, each curd layer having a leading end and a trailing end, said whey draining through said first porous conveying member, means for collecting the whey draining through said first conveying member, second conveyor means including a second porous conveying member and having an upstream end disposed at a lower level than the downstream end of said first conveyor means and disposed to receive each curd layer from the downstream end of said first conveyor means, second drive means for driving said second conveyor means, means responsive to the leading end of each curd layer approaching the downstream end of said first conveyor means for decreasing the speed of said firtst drive means to approximate the speed of said second drive means so that each curd layer is transferred from said first conveyor means to said second conveyor means while said first and second conveyor means are operating at approximately the same speed, and means responsive to the trailing end of each curd layer leaving said first conveyor means for increasing the speed of said first drive means to a speed faster than the speed of said second drive means.
A continuous cheese matting apparatus, comprising first conveyor means including a first porous conveying member and having an upstream end and a downstream end, feed means for feeding a mixture of curds and whey to the upstream end of said first conveyor means to form a curd layer having a leading end and a trailing end, second conveyor means including a second porous conveying member and having an upstream end disposed at a lower level than the downstream end of said first conveyor means and disposed to receive said curd layer from the downstream end of said first conveyor means, said whey draining through said first and second porous conveying members, third conveyor means disposed beneath said second conveyor means, transfer means for transferring said curd layer from the downstream end of said second conveyor means to the upstream end of said third conveyor means and inverting said curd layer during the transfer, fourth conveyor means having an upstream end disposed at a level beneath the downstream end of said third conveyor means and disposed to receive said curd layer from said third conveyor means, curd cutting means disposed at the downstream end of said fourth conveyor means for cutting the curd layer into chunks, means responsive to the leading edge of said curd layer approaching the downstream end of said first conveyor means for decreasing the speed of said first conveyor means to provide said first conveyor means with a speed approximating the speed of said second conveyor means so that said curd layer is transferred from said first conveyor means to said second conveyor means while said first and second conveyor means are operating at approximately the same speed, means responsive to the trailing end of said curd layer moving from said first conveyor means for increasing the speed of said first conveyor means, means responsive to the leading end of said curd layer approaching the downstream end of said third conveyor means for varying the speed of said fourth conveyor means to approximate the speed of said third conveyor means so that said curd layer is transferred to said fourth conveyor means while said third and fourth conveyor means are operating at approximately the same speed, and means responsive to the trailing end of said curd layer moving onto said fourth conveyor means for varying the speed of said fourth conveyor means to a value different from the speed of said third conveyor means.
A continuous cheese matting apparatus, comprising first conveyor means including a first porous conveying member and having an upstream end and a downstream end, feed means for feed separate batches of curds and whey onto the upstream end of said first conveyor means to form separate longitudinally spaced curd layers, each curd layer having a leading end and a trailing end, second conveyor means including a second porous conveying member and having an upstream end disposed at a lower level than the downstream end of said first conveyor means and disposed to receive each curd layer from the downstream end of said first conveyor means, said whey draining through said first and second porous conveying members, third conveyor means including a third porous conveying member and disposed beneath said second conveyor means, transfer means for transferring each curd layer from the downstream end of said second conveyor means to the upstream end of said third conveyor means and inverting said layer during the transfer, fourth conveyor means having an upstream end disposed at a level beneath the downstream end of said third conveyor means and disposed to receive each curd layer from said third conveyor means, means responsive to the leading end of each curd layer approaching the downstream end of said first conveyor means for reducing the speed of said first conveyor means to approximate the speed of said second conveyor means so that each curd layer is transferred from said first conveyor means to said second conveyor means while said first and second conveyor means are operating at approximately the same speed, and means responsive to the leading end of each curd layer approaching the downstream end of said third conveyor means for varying the speed of said fourth conveyor means to approximate the speed of said third conveyor means, so that said curd layer is transferred to said fourth conveyor means while said third and fourth conveyor means are operating at approximately the same speed.
A feeding mechanism for feeding a mixture of curds and whey to a moving conveyor member, comprising receiving means disposed above said conveying member and including an imperforate downwardly sloping trough, supply means for supplying a mixture of curds and whey to said trough, and baffle means extending downwardly from the lower end of said sloping trough to a location immediately above said conveying member, and drainage port means in said baffle means for draining whey from said mixture.
