Energy efficient processing
The HRS I Series offers options to de-pack and crush then melt frozen fruit juice ready for storage or further processing. The IC Series features a roller conveyor which feeds individual drums into a tipper that empties them into the crusher. Here, a specially designed spiked roller crushes the solid ice into an icy slush, which is then transferred to the IM Series re-melting device.
Based on the corrugated tube heat exchanger technology for which HRS is renowned, the IM Series raises the temperature of the juice from frozen to around 4 ° C in 90 seconds. As well as maintaining juice quality through rapid warming, thanks to the use of corrugated tube heat exchangers, the system is much more energy efficient than alternatives such as those using heating elements – saving both time and money during this key process step.
When it comes to energy efficient pasteurisation, both the HRS MI and MR Series of pasteurisers are suitable for the rapid pasteurisation required for premium juice production. By using a corrugated tube design the orange juice can be heated up to pasteurisation temperature much faster – typically by up to 30 %. Because of the high heat transfer rates provided by the corrugated tube technique, HRS’ s pasteurisation systems also use water at a lower temperature to reduce the risk of product damage. Another benefit of higher heat transfer rates is that the system footprint can be reduced by using shorter heat exchanger pipes. The shorter length of the heat exchanger also results in a reduction in pressure drop, which saves pumping power and further reduces energy costs by as much as 40 %.
HRS also offers an ohmic pasteurisation system which uses electricity to heat the product rapidly and uniformly, has been scientifically shown to be highly effective while maintaining flavours and quality. This system heats the juice to 105 ° C within one second, where it is held at this temperature for four seconds and then cooled.
