New designs in heat exchangers improve regeneration efficiencies, while adding ease of maintenance
Plate heat exchangers are used for a variety of purposes in dairy processing operations. Some major applications include HTST units (for milk, cheese-milk, ice cream), raw milk receiving coolers, and by-product (yogurt, cream) heater/coolers. Scraped surface heat exchangers are used for large particulate laden products or products which tend to crystallize during processing. There are numerous factors governing the design of a heat exchanger. For instance the product type, flowrate, temperature profile, pressure drop considerations and future expandability requirement are important design criteria when sizing a unit.
