For pasteurizing milk, is it recommended to use HTST, ESL, or UHT pasteurization? I've heard different things from different people. Is the type of equipment and financial cost comparable?

For pasteurization it usually comes down to what a company or person can afford. UHT (Ultra High Temperature) is extremely expensive, because this method is more modern, and the industry needs more time and competition to lower the cost for UHT. There is one UHT system in Wisconsin and it was over a million in cost. HTST (High Temp, Short Time) is flash pasteurization and is typically used for large amounts of product. If you are pasteurizing 1,000 lbs per hour plus then this might be a great method....typical cost of HTST is around 110K to 150K and higher depending on parameters needed. Batch Pasteurization is the oldest and most affordable, this cost can be as little as 15K to around 75K depending on gallon size of the tank. This method uses the traditional 30 min hold time in the tank at a specific temperature and is the most affordable for most customers.

UHT $1,000,000.00  Typical Price

HTST $120,000.00    Typical Price

Batch $25,000.00     Typical Price

The answer to this question depends on which type of product you are trying to sell.  A HTST pasteurizer is designed to pasteurize product at 161 F for 15 seconds on a continuous basis.  Product pasteurized this way may be sold in stores as liquid milk, made into cheese, yogurt or ice cream.  The shelf life of these products is typically measured in weeks.  UHT pasteurization is designed to destroy bacterial spores that cause spoilage.  Products produced using this process are heated to almost 300 F with a very short time, but they have a shelf life measured in months without refrigeration.    ESL milk is treated at about 250 F and has shelf life between HTST and UHT.  We manufacture stand along systems that can pasteurize milk according to all three standards, or all three in the same system.  If properly executed, there is not a significant cost difference between the systems.  Our UHT systems are in service all over the country and typically cost between $400k - $700k.  A well designed pasteurizer will be able to utilize energy recovery technologies so the operating cost is low.
