Whey process equipment

Tender description

To engineer, supply, install and commission a complete fully automated process plant for processing of whey. The plant should be sized to be able to handle approximately 27,000 lph of whey from the cheese vats on a 24/7 basis. The whey comprises a mixed stream of both sweet and salty wheys from hard pressed and territorial “crumbly” recipes. The whey should have fat separated to produce 40% fat cream which will require pasteurisation and storage prior to tanker despatch. The pasteurised whey stream is then buffered prior to concentration in an RO plant to a minimum of 24% solids. Ideally SCC wish to concentrate up to 30% total solids and so consideration should be given to this requirement in the design. The permeate from the RO plant is further treated in an RO polisher so as to produce water for CIP cleaning and product purges of the entire whey process plant. The required Polished water storage and ring main form a part of the project scope. Whey concentrate from the RO plant is buffered prior to tanker despatch. The dimensioning of the plant in terms of vessel capacities and flow rates for pasteurisers and membrane plants is critical to ensure that the cheese vats can operate continuously without any bottleneck caused by this downstream process. The entire plant is to be cleaned by a new CIP unit which forms a part of the scope of work. Please refer to the attached block diagram for a pictoral representation of the scope of work.
