Juice concentrate pasteurization: How to improve energy efficiency and cut total cost of ownership?

During juice pasteurization, viscosity has a major impact on the energy efficiency of the gasketed-plate-and-frame heat exchanger and feed pump. In this article, learn more about how to improve efficiency and at the same time, reduce total cost of ownership.

World juice consumption

In 2017, 70% of the world’s commercial orange juice was produced in Brazil and 65% of it was exported to Europe. This scenario is typical of juice production because favourable growing conditions for the different types of fruits are found in so few countries worldwide. The fruits are processed locally into juice and then exported across continents for consumption (source: beveragedaily.com). 

Depending on the type of fruit and the target market, juice is either shipped as single-strength premium orange juice or concentrated to reduce transportation costs and then re-diluted in bottling stations close to the point of consumption. About 70% of the 20.6 million tons pure fruit juice consumed worldwide in 2017 was reconstituted from concentrate according to the strategic market research company Euromonitor.

Heat treatment of juices and energy consumption

During the process, pasteurization or UHT treatment is carried out to ensure juice shelf life during shipping and storage. These heat treatments directly impact juice production costs due to the amount of energy used.

During production, energy consumption may fluctuate. The higher the viscosity of a product, the more energy is required. High product viscosity affects the pump efficiency as well as the heat transfer efficiency of heat exchangers on food processing lines; it also reduces throughput.

Better energy efficiency and reducing total cost of ownership

To help manufacturers achieve more in their juice production, we have produced a white paper to look into combining heat exchanger and feed pump selection to reduce energy consumption. Download the paper below to learn more.
