The constraint that stops a dairy operation growing is almost never the one people buy equipment for. It is space to keep things cold, and then time to clean.

Cold storage

Finished product needs refrigerated space and so does incoming milk, and neither can wait. Cold space is expensive per square foot, has to be monitored, and fills up at exactly the moment production goes well. It is the first hard wall.

Cleaning, which is production time

Dairy equipment has to be cleaned thoroughly and often, and that cleaning is not a background task. At volume it occupies a substantial share of the working day, and adding products or changeovers adds to it directly. Many operations hit a ceiling set by cleaning hours long before one set by capacity.

The delivery round

Short shelf life means frequent delivery, and frequent delivery to scattered stockists consumes a day that cannot also be a production day. Growth in the number of accounts can reduce output, which is a surprising result until it happens.

Pasteurizing capacity is rarely the limit

It is the most visible piece of equipment and the one people assume is the bottleneck, and in practice it is usually sized ahead of the rest. Check which constraint you actually have before buying a bigger one.

Where to spend first

Cold storage, and then anything that reduces cleaning time, such as equipment designed to be cleaned in place. Both buy capacity without adding a delivery day, and both make the current operation better rather than only enabling a larger one.

Count cleaning as production hours

If it is not in the schedule it will be done in the evening by somebody tired, which is where it gets shortened. Scheduling it as production time makes the real capacity visible and stops a growth plan being built on hours that do not exist.
