liquid Food Deaerators & Deodorisers

•If not removed the air and gases will cause problems.

•More air is incorporated into the products during handling.

•Liquids always contain a certain amount of air and gases.

Air and gases in food products

Deaerators & Deodorizers

Eliminate dissolved and dispersed air and gases

Retention of aromatics and nutrient values

Removal of off-flavours and odours

Concentration of total solids

Increase shelf life and storage stability

Air and gases in food occur in three states:

Deaerators & Deodorizers

Inaccurate volumetric measurement

Reduced operation hours (fouling on heat exchanger surface)

Degradation of vitamins and loss of nutrient values

Reduced shelf stability

Visible problems e.g de-colouring, browning, large air bubbles
