Abstract

A support structure for a whey draining belt includes a beam formed of a metal material, and a slide plate formed of a plastic material and fixedly connectable to an upper part of the beam for allowing the whey draining belt to slide over the slide plate.

First claim

The invention claimed is:

1. A support structure for a whey draining belt, the support structure comprising:
a beam formed of a metal material; and
a slide plate formed of a plastic material and fixedly connectable to an upper part of the beam for allowing the whey draining belt to slide over the slide plate.

2. The support structure according to claim 1 , wherein the beam comprises at least one pin that extends upwardly from the beam to engage against the slide plate.

3. The support structure according to claim 2 , wherein the slide plate comprises at least one opening for receiving the at least one pin.

4. The support structure according to claim 3 , wherein the slide plate comprises a plurality of openings that are spaced along opposing sides of the slide plate and the beam comprises a plurality of pins corresponding to the plurality of openings.

5. The support structure according to claim 4 , wherein the slide plate is slidable in a longitudinal direction of the slide plate, from an insertion position in which the plurality of pins are received in the plurality of openings to an assembled position in which the plurality of pins are offset from the plurality of openings to engage the opposing sides of the slide plate.

6. The support structure according to claim 2 , wherein the at least one pin comprises a pillar and a head that is arranged on the pillar.

7. The support structure according to claim 6 , wherein the head and the slide plate are configured to engage with a point contact or a line contact.

8. The support structure according to claim 6 , wherein the slide plate comprises a chamfered top surface that is arranged to abut the head of the at least one pin.

9. The support structure according to claim 8 , wherein a chamfer of the chamfered top surface is angled at an angle that is different from an angle of a slide plate-engaging surface of the head to provide the contact between the slide plate and the head.

10. The support structure (according to claim 1 , comprising a stopper that is arranged on the beam and engageable with an end of the slide plate for positioning the slide plate in a longitudinal direction of the slide plate.

11. The support structure according to claim 1 , wherein the slide plate comprises a plurality of drainage openings.

12. A whey draining machine comprising a plurality of whey draining belts supported by a plurality of support structures according to claim 1 ,
wherein the plurality of support structures form a set of support structures in which the support structures are arranged in parallel to each other in a transverse direction relative to a direction of travel of the plurality of whey draining belts, and separated in the transverse direction by interspaces between the support structures.

13. The whey draining machine according to claim 12 , wherein the set of support structures is a first set of support structures, the whey draining machine comprising a second, similar set of support structures relative to the first set of support structures, the second set of support structures being arranged downstream the first set of support structures and offset in the transverse direction relative to the first set of support structures by a distance that aligns, in the direction of travel, the support structures of the first set with the interspaces of the second set.

14. The whey draining machine according to claim 12 , comprising an inlet for receiving a curd and whey mixture and an outlet for discharging the curd after the curd is drained of whey, wherein the whey draining belt is arranged to move the curd from the inlet towards the outlet.

15. A method of draining whey from a curd and whey mixture, comprising:
receiving a curd and whey mixture on a whey draining belt supported by a support structure having a beam formed of a metal material, and a slide plate formed of a plastic material and fixedly connectable to an upper part of the beam for allowing the whey draining belt to slide over the slide plate; and
draining the whey from the curd and whey mixture as the whey draining belt slides over the slide plate to form curd.
