1. A process for manufacturing an animal feed block according to a target constituent formulation in an apparatus which comprises (A) in a dry feeding zone, a first dry feeder which includes a first dry hopper charged with a dry pre-mix and a first material handling conveyor and a second dry feeder
1. A process for manufacturing an animal feed block according to a target constituent formulation in an apparatus which comprises (A) in a dry feeding zone, a first dry feeder which includes a first dry hopper charged with a dry pre-mix and a first material handling conveyor and a second dry feeder which includes a second dry hopper charged with an active ingredient and a second material handling conveyor,(B) in a dry mixing zone downstream from the dry feeding zone, a dry mixer and an under hopper downstream from the dry mixer,(C) in a liquid feeding zone, a first liquid feeder which includes a first liquid feeding device and a first liquid tank charged with a wet pre-mix which includes a liquid by-product and a liquid additive,(D) a slurry mixer downstream from the dry mixing zone and the liquid feeding zone and(E) a dispensing assembly downstream from the slurry mixer, the process comprising: (A1) discharging and conveying the dry pre-mix from the first dry hopper to the dry mixer by the first material handling conveyor;(A2) measuring the cumulative weight of the dry pre-mix in the dry mixer;(A3) calculating a target weight of active ingredient to be conveyed to the dry mixer, wherein the target weight of the active ingredient and the cumulative weight of the dry pre-mix are constituently proportionate to the target constituent formulation;(A4) discharging and conveying the active ingredient from the second dry hopper to the dry mixer by the second material handling conveyor;(A5) during step (A4)either measuring the loss in weight of the active ingredient in the second dry hopper and causing step (A4) to cease when the loss in weight of the active ingredient equates to the target weight of the active ingredient calculated in step (A3)or measuring the weight of dry material in the dry mixer and causing step (A4) to cease when the weight of dry material in the dry mixer equates to the sum of the target weight of the active ingredient calculated in step (A3) and the cumulative weight of the dry pre-mix measured in step (A2);(B1) mixing the active ingredient and the dry pre-mix in the dry mixer into a substantially homogeneous dry mix;(B2) discharging the substantially homogeneous dry mix into the under hopper;(B3) measuring the weight of the substantially homogeneous dry mix in the under hopper;(B4) discharging and conveying the substantially homogeneous dry mix from the under hopper to the slurry mixer;(B5) measuring the rate of the loss in weight of the substantially homogeneous dry mix in the under hopper during step (B4);(C1) calculating a target flow rate of the wet pre-mix to be conveyed to the slurry mixer, wherein the target flow rate of the wet pre-mix and the rate of the loss in weight of the substantially homogeneous dry mix measured in step (B5) are constituently proportionate to the target constituent formulation;(C2) discharging and conveying the wet pre-mix from the first liquid tank to the slurry mixer at an actual flow rate;(C3) measuring the actual flow rate of the wet pre-mix;(C4) adjusting continuously the actual flow rate to achieve the target flow rate;(D1) mixing the substantially homogeneous dry mix and the wet pre-mix in the slurry mixer into a substantially homogeneous slurry;(E1) discharging the substantially homogeneous slurry into the dispensing assembly;(E2) dispensing the substantially homogeneous slurry portionwise from the dispensing assembly into receptacles; and(E3) allowing the substantially homogeneous slurry in each receptacle to cool to form an animal feed block. 2. The process as recited in claim 1 further comprising: (A6) calculating a target weight of wet pre-mix to be conveyed to the slurry mixer, wherein the target weight of the wet pre-mix and the cumulative weight of the dry pre-mix are constituently proportionate to the target constituent formulation. 3. The process as recited in claim 1 wherein the dry pre-mix comprises a dry protein and a dry mineral. 4. The process as recited in claim 1 wherein the liquid by-product is or includes molasses. 5. The process as recited in claim 1 wherein step (A5) is carried out during step (A4) by measuring the weight of dry material in the dry mixer and causing step (A4) to cease when the weight of dry material in the dry mixer equates to the sum of the target weight of the active ingredient calculated in step (A3) and the cumulative weight of the dry pre-mix measured in step (A2). 6. The process as recited in claim 1 carried out without heating. 7. The process as recited in claim 1 wherein step (B4) is carried out by a variable speed material handling conveyor. 8. The process as recited in claim 7 wherein when the actual flow rate approximates consistently to the target flow rate, the process further comprises: (D2) locking the speed of the slurry mixer;(D3) locking the speed of the variable speed material handling conveyor. 9. The process as recited in claim 1 further comprising: (D4) causing step (C2) to cease when the rate of the loss in weight measured in step (B5) is zero. 10. The process as recited in claim 1 wherein the ratio of the weight of wet pre-mix to dry pre-mix in the target constituent formulation is in the range 0.50:1 to 0.60:1. 11. The process as recited in claim 1 wherein the amount of liquid by-product in the target constituent formulation is in the range 30 to 35 wt %. 12. The process as recited in claim 1 wherein the liquid by-product is selected from the group consisting of sugar cane molasses, sugar beet molasses, starch molasses, citrus molasses, pot ale syrup, whey, corn steep liquor, stillage and a mixture thereof. 13. The process as recited in claim 4 wherein the amount of molasses in the target constituent formulation is in the range 9 to 11 wt %. 14. The process as recited in claim 1 wherein the liquid additive is vegetable oil. 15. The process as recited in claim 1 wherein the active ingredient is calcium oxide. 16. The process as recited in claim 15 wherein the amount of active ingredient in the target constituent formulation is in the range 3.0 to 4.0 wt %. 17. The process as recited in claim 1 wherein the dry pre-mix comprises a source of carbohydrate, a source of nitrogen, a source of protein or a source of fat. 18. The process as recited in claim 1 wherein the dry pre-mix comprises a dry ingredient selected from the group consisting of a vitamin, a mineral, a protein, a flavouring, a colourant, a preservative, a pharmaceutical, a stabiliser, a fat, a nutritional supplement, a dietary supplement, a carbohydrate, soapstock, urea, lignin sulphonate, lecithin, fibres and a mixture thereof. 19. The process as recited in claim 1 further comprising: (E2a) advancing the receptacles consecutively on a receptacle conveyor to beneath a mechanical leveler;(E2b) mechanically levelling the homogeneous slurry in each receptacle using the mechanical leveler.
