The Armfield Microwave UHT /HTST unit has been developed for the rapid heating of various types of viscous, non-viscous and even non-homogeneous products. Product temperatures up to 160°C can be reached. The Armfield FT84-12 can be used with an Armfield FT174X, FT74X, FT74XTS or FT94X to provide a rapid microwave final heating stage.
The Armfield Microwave UHT/HTST unit has been developed for the rapid heating of various types of viscous, non-viscous and even non-homogeneous products. Product temperatures up to 160°C can be reached. The product is heated in a short product tube enabling extremely rapid heating rates to be achieved.
This extremely high heating rate reduces negative effects on the physical properties of the product, eg denaturation of proteins, vitamins and Maillard reaction.
Another advantage of the microwave unit is that the heating occurs throughout the volume of the product. No heated surface is needed, which prevents burning of the product.
The Microwave UHT/HTST is a user-friendly laboratory system for pasteurisation, sterilisation, gelatinisation and other heating processes.
The FT84-12 is an add-on unit, which must be used in conjunction with an Armfield FT74X Tubular system. The FT74XTS is still available for independent use, but the FT84-12 cannot be operated without the FT74X/FT74XTS.
By purchasing an FT84-12, existing FT74X/FT74XTS owners can upgrade their equipment to a full performance microwave unit at minimum cost (FT74X/FT74XTS Plate Heat Exchanger units will need the Tubular Heat Exchanger option as well).
The FT84-12 is placed inline with the FT74x/FT74XTS, using food-quality couplings and flexible hoses, allowing the heating section to be used for product preheat. The FT84-12 includes an initial precooler close to the microwave applicator, with the main cooling provided by the FT74X/FT74XTS.
The combination of the FT74X/FT74XTS (tubular) and the FT84-12 provides complete flexibility and all the advantages of both tubular and microwave heating systems.
