Case Study - Dairies


2 million British cows enable dairy producers to supply the UK public with 5 billion bottles of milk a year. There is no possibility of long term storage and each different method of heating milk, needs despatching on the first truck available to waiting populations at retailers across the country. Glass, plastic and cardboard packaging is all used to ensure our milk arrives fresh and contamination free. None of these would make it to market without the assistance of a end of line sealer or dairy shrink wrap machine.

Project Specifications: Making a wholesale change such as moving from bottling to plastic bottles means a wholly different dairy production line is required. A problem in the planning process was how a machine running glass containers could handle squeezable bottles. Grips would need to be less tight and infeed lines adjusted with a new sealing bar dairy shrink machine required to seal effectively and wrap the plastic bottles into packs at the end.

Overview: Some of the equipment on site, while old, simply needed custom changes made. Speed of line tests were ensured and all products measured. As previously all glass bottles were the same size but the new plastic bottles would come in three shapes of varying measurements. 1 litre, 2 litres and three. Machines need adapting along the line and new heat sealer fr the carton with the correct temperature maintained throughout would need to be installed. The placing of packaging around the assembled units was enabled through the use of an overwrap dairy shrink wrap machine rather than with sealing bar.

A dairy shrink wrap case study is a per milk production assessment and review and no two will be the same. Contact us today for a brief chat about your dairy production and distribution needs. This study involved adapting existing product line machines, and conveyor belts for sorting and laser adapted to resize. A new SM6040 shrink tunnel chamber with replacement heavy duty infeed belts.

Project Comment:

"Producing milk and changing the delivery method was a wholesale change for this manufacturer. Moving from glass to plastic meant speeds could increase to 80 packs a minute, not only taking milk to market quicker but finishing the staff's working day earlier, reducing expenses. The new units and those adapted would deliver long term reductions on electricity use, wastage and overall noise output was reduced significantly."
