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.
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.
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.
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.
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.
