What is a pasteurization machine?
HTST pasteurization equipment uses Sanitary Plate Heat Exchangers utilizing hot water or steam to raise the temperature of products. This heating stage is then followed by a rapid cooling stage. The pasteurization temperature and time depend on the product.
Does pasteurisation preserve food?
Today, the process of pasteurisation is widely used within the food and drink industry, and it is the most common form of heat treatment used on milk within Northern Ireland. Pasteurisation makes sure milk is safe to drink (by killing any bacteria) and also helps to prolong its shelf life.

30 minutes
Pasteurization of milk, widely practiced in several countries, notably the United States, requires temperatures of about 63 °C (145 °F) maintained for 30 minutes or, alternatively, heating to a higher temperature, 72 °C (162 °F), and holding for 15 seconds (and yet higher temperatures for shorter periods of time).
