The Marriott Walker Corporation supplies evaporators of various types and sizes to the food and dairy industries. In addition to new systems, our team can also provide solutions for existing systems to improve, compliment or replace equipment where necessary. From Pilot Plant units to Production Evaporators, the Marriott Walker Corporation will analyze a processor’s application and develop a design to suit their needs.

Production Evaporators

The Marriott Walker Corporation proudly offers a range of custom designed evaporators for food and dairy products. Production evaporators, of either the TVR or MVR configurations, are available in a range of sizes to suit your needs. In addition to the basic evaporator, Marriot Walker Corporation can also provide HTST pasteurizers, heat treatment holding tubes and hotwells, as well as post-evaporation flash coolers.

Vacuum Pans

Prior to the development of multiple-effect, continuously operating evaporators, the standard evaporating procedure was to use a “batch operated” evaporator called a vacuum pan, in which the product to be condensed is “cooked down” under vacuum, within one vessel. Vacuum pans are still used in a variety of special applications and they can have internal heating coils, or the product heating can be accomplished in a jacketed vacuum vessel. The external shell must be provided with a separate condenser and vacuum pump, to permit the unit to operate at the desired temperature.

Pilot Plant Units

The Marriott Walker Corporation has provided numerous pilot plant evaporators for commercial R&D facilities as well as university teaching facilities. Our pilot plant evaporators are always custom designed to suit a processor’s specific needs.

If your facility would benefit from the flexibility offered by having an “in house” pilot plant evaporator, please contact us.
