Pasteurizers

Standard HTST milk pasteurisation runs at a minimum of 72 degrees Celsius held for 15 seconds, while batch processing uses around 63 degrees for 30 minutes. Other products have their own validated combinations depending on composition and target organisms. Your process authority or regulator confirms the requirement, and the machine must prove it can hold and record that profile.

Request recent plate integrity test results, check the holding tube matches the required residence time at your flow rate, and confirm the flow diversion valve operates correctly on temperature deviation. Instrumentation including the recording thermograph must work and calibrate. A plant with current documentation from a regulated dairy transfers with minimal compliance risk.

Plate pasteurisers preheat incoming cold product with outgoing hot product, recovering typically 85 to 95 percent of the heat energy. That single design feature is why continuous plants cost so little to run per litre compared with batch heating. When comparing listings, the regeneration percentage is one of the most financially significant specifications on the sheet.

Yes, within limits set by viscosity, particulates, and required process profiles. Plate systems handle thin liquids interchangeably with CIP between products, while thick or particulate recipes need tubular designs. Changing between product categories may require revalidation of the process, so plan your product range before selecting the technology.

Continuous plants are rated in litres per hour and run best at steady design flow, so match the rating to your realistic daily volume across your processing window. Undersized plants stretch processing hours, while oversized ones cycle inefficiently and clean more often than they run. Sellers can tell you the throughput their plant sustained, which is a more reliable guide than nameplate capacity alone.
