Crossflow filtration has been around for years, but its potential for energy-efficiency and self-sufficiency is making it one of the biggest trends in wine making.
For wine makers, the need for filtration is a given. To produce a bottle of stable, great tasting wine somewhere along the winemaking process the batch needs to be filtered. The decision of which crossflow filtration system to use is a complex one, but many overlook an important but basic step in the filtration process: hot water.
Crossflow filtration requires clean hot water that is readily available and can be quickly generated for one if not two consecutive sanitation flushes. The use of instant hot water units is common but not necessarily the best option.
Assuming manufacturing specification for a crossflow system requires the use of 850 litres of 65/700C water and, to achieve the best results, the flow needs to be consistently at the required temperature and volume then an instant hot water system may struggle to meet demand. A crossflow system like this would require a number of instant hot water units set up in series to achieve the required temperature and flow combination, generally resulting in a slower and less stable process.
'Using instant hot water units can slow flow rates
and add time to achieving sanitation,
whereas hot water storage systems
designed by Travhotec can alleviate this issue
and ensure there is no impact on productivity.'
The most desirable method is to have a volume of water which has been heated to the correct temperature and has the capacity to carry out the cycle twice. Should the sanitation process not be completed correctly or on time, then a second volume would be needed quickly, so a storing capacity for two washes is desirable.
Using instant hot water units can slow flow rates and add time to achieving sanitation, whereas hot water storage systems designed by Travhotec can alleviate this issue and ensure there is no impact on productivity.
Storing water can be more efficient because state-of-the-art condensing boilers can be used, offering considerable savings on gas consumption. When water is heated in a Travhotec system, no cold is
added so less energy is consumed during the sanitation process. In remote locations diesel boilers can be a viable alternative with storage systems. Furthermore, our systems can be used for high temperature sanitation in bottling lines and at low temperatures for safe and very efficient wine heating, adding to their appeal for winemakers.
There are concerns within the wine industry that instant hot water units and older copper-based hot water boilers, can contaminate water by leaching from the heating coil and in so contaminate the filters.
Systems designed by Travhotec ensure all sanitation hot water used in the sanitation process is only in contact with stainless steel, significantly reducing the risk of contamination.
With proper maintenance and servicing, Travhotec systems frequently last over 15 years, whereas an instant hot water unit would not have the same sort life expectancy. Another cost saving.
