Vacuum Processing Applications


We specialize in Vacuum Process for Food Applications.

Evaporative Cooling with Steam Jet Vacuum Systems

Ejector Vacuum systems are used to cool various food products such as soups, potatoes, juices, sauces, vegetables and other moisture rich products. Typically cooling temperatures range from 240 degrees Fahrenheit to 35 degrees Fahrenheit and can be achieved in 10 to 25 minutes depending on product quantity and Ejector size.


Cooking and Cooling in the Same Vessel

Cooking and cooling can be achieved in the same vessel, whether retort or jacketed kettle, resulting in less process time and handling.


Heat Sensitive Products

In cases where the product is heat sensitive, vacuum is used to maintain a constant temperature during the process to prevent damage and maintain quality. Such applications usually operate at temperatures 80 degrees Fahrenheit and higher.


Typical Three Stage Vacuum System for cooling liquids such as Soups, Sauces, Jellies & Slurries in a Jacketed Kettle . Agitation is required to expose as much product to the vacuum, especially for viscous products.

Typical Three Stage Vacuum System for cooling solid products such as potatoes, Chick Peas & Diced Vegetables in a Retort. Products are placed in baskets or trays on carts.
