The Tetra Pak® Cheddaring 5 machine is designed for continuous production of fused and stirred Cheddar and pasta filata cheese types. It is a totally enclosed machine, designed to automatically drain, acidify, texture, mill, salt and mellow cheese curd.
Capacity ranges from 1,000 – 16,000 kg/hr.
First inlet screen
There are 9 litres of whey for every litre of curd. Made of stainless steel wedge wire, the inlet screen has gaps of just 0.25 mm between each wedge. This means a high proportion of the liquid can drain through the holes, but very few curd particles pass through.
Second whey screen
Any rogue curd particles that have not been caught by the first inlet screen, are caught in this, the second whey screen. All the whey that passes through the screen is immediately collected before it has had time to accumulate bacteria – so it can be categorized as ‘high-quality whey’.
Baffle plates are strategically placed in the channel, generating turbulence in the mixture and ensuring the curds are evenly distributed across the width of the belt. This gives an even process throughout the mixture, and leads to a more consistent end product.
Draining belt with tapered perforations
The draining belt has tapered slots through which the curd particles pass. Once they have passed through the narrowest point – the inlet - the curd particles can fall through the wider part of the hole easily, without the risk of clogging.
Draining boosting stirrer
If pockets of whey accumulate on top of the curd mat, they simply remain there, leading to an uneven moisture distribution. This stirrer eliminates this problem by breaking up the curd mat so the whey can drain off through the perforated belt.
CIP separation hatch
The CIP separation hatch closes off part of the machine so pre-rinsing can begin in the upper house, even while product is still being removed from the lower house. This shortens the waiting time between production runs.
Fish bone belt support
The belt support has an open fish bone design which delivers a number of benefits. The most important one is that it reduces the level of friction between the belt and the support, so the belt can run smoothly without jumping. It gives an even wear across the belt, and does not leave black wear marks (that can occur when parallel support is used). Finally, it’s much easier to clean than a closed design since there are no CIP blind spots.
Low friction plastic side guides rest on the belt itself. The absence of a gap between the belt and the guides means curds cannot escape through the sides. In this way, it prevents product losses. The guides also eliminate the possible issue of black spots on the cheese - which can be caused by stainless steel residue in a traditional design. Since the cheese is not in direct contact with the stainless-steel housing, heat losses are minimized, contributing to a consistent output.
