Pasteurizers & Sterilizers

Pasteurisation applies moderate heat to destroy pathogens and reduce spoilage organisms, giving a chilled shelf life measured in days or weeks. Sterilisation applies far more severe heat to destroy spores as well, producing shelf stable product that keeps for months at ambient temperature. The choice is set by your product formulation, distribution model and the regulations covering your category.

Ask for the original process design specification, holding tube dimensions, instrument calibration records and any regulatory approvals the system operated under. The flow diversion valve test history matters particularly, since that valve is the safety heart of an HTST system. Missing documentation does not rule a machine out, but it adds validation work you should price in.

Regulators approve the installed process, not the machine in isolation, so any relocated system needs commissioning, calibration and validation at your site before production. A structurally sound used pasteuriser with good records passes this process routinely. Engage your environmental health or dairy inspector early so requirements are clear before installation starts.

Match the rated flow to your peak weekly production compressed into realistic processing windows, then allow for growth of at least a couple of years. Running a continuous system far below its design flow causes control problems, so oversizing has real costs too. Batch vats bridge the gap nicely for producers not yet ready for continuous flow.

Many are, and qualifying listings display financing availability directly. Spreading the cost of a processing skid across its service life aligns spend with the revenue it generates. Terms are discussed as part of your enquiry, alongside logistics and any commissioning support the seller offers.
