Many prepared food products would quickly foul normal types of heat exchangers, because they’re viscous or sticky, contain particles or alter state when heated.
The new generation of Contherm scraped-surface heat exchangers from Alfa Laval is updated with four new performance enhancements that extend the capabilities of the Contherm range. This means enhanced food safety initiatives, even more gentle treatment of the product and improved resistance to wear and chemical corrosion. An upgrading service named, ConthermFlex, is also available. This gives customers with old scraped surface technology an opportunity to upgrade their equipment.
Finally, there’s a newly developed, larger Contherm 6 x 11 with 15 % more surface area and up to 25 per cent more capacity than traditional sizes.
The Contherm SSHE can be modified to form the Convap evaporator, which is particularly suited to concentrating viscous products. The system normally operates under vacuum. The entrainment separator connected to the SSHE by means of a specially designed vapor head allows the
separation of the concentrate from the vapor phase.
For shear sensitive and particulate laden food and confectionary that are susceptible to degradation, Alfa Laval has developed a new optional low shear particulate rotor. It can be used in both new and existing Contherm units.
ConVap, a modified Contherm evaporator and condenser, removes moisture from viscous food products to high solids levels.
