A Guide to Reducing Energy Consumption in Your Food Processing Evaporator SystemsEvaporators are widely used in the food processing industry to remove a portion of the water from food products. This reduces bulk and weight for subsequent processing, increases solids content (as for jams and molasses), helps preserve the product, provides convenience to the end consumer and concentrates color or flavor.
Description of the Technology
Many types of evaporators are in use, most with certain common features:
Evaporators may operate singly or several may operate in series. Each one is referred to as an effect and in multiple-effect systems, the product output from one effect is the feed for the following effect. Similarly, higher-temperature vapor driven out of the product in one effect is used to heat lower-temperature product in another. Efficiency is gained by using multiple-effect systems.
Energy Efficiency Measures
Several changes can be made to evaporator systems to improve their efficiency. Here are some of them:
Operations Tips to Improve Energy Efficiency
The following list provides operating practices that can reduce energy consumption in your evaporators:
Maintenance Tips to Improve Energy Efficiency
Regular maintenance will help ensure that equipment serves a long, useful life and also operates efficiently. The following suggestions will help keep your evaporators operating efficiently:
