The process

Thermal treatment using XLG® corrugated tube heat exchangers takes place more rapidly than with other tubular heat exchangers because the heat transfer coefficient – the numerical value representing the rate of transfer of heat from one fluid to another – is significantly higher, allowing a more rapid treatment. The result is obvious: juices which are pasteurised in corrugated tube heat exchangers retain more of their natural properties as less time is needed for their treatment; they are exposed to the high temperature for less time and to the degradation in their natural properties that this causes.

XLG® corrugated tube heat exchangers can process any type of fruit juice with pulp or fibres as well as other drinks containing particles, concentrates, purées, grape must etc..
