INOXPA has developed a new range of heat treatment equipment, aimed mainly at the dairy industry, based on the high temperature-short time (HTST)-type heat exchangers commonly used in this sector.
The units are modular and assembled on skids, the equipment is semi-automatic, which means that it is easy to handle and can rapidly be started-up.
This equipment can be used to perform the following processes related to the dairy industry: heat treatment of milk for storage and subsequent production, pasteurisation of milk for packaging as short shelf life fresh milk, pasteurisation of milk for the production of cheese and yoghurt, and pasteurisation of cream, whey and other derivatives. 
It is designed to handle flows of 500, 1000, 2000,3000 and 5000 l/h and can be configured with various treatment stages, including heating only, heating and cooling, energy recovery–heat and cool, and with a fourth stage with an outlet for skimming, sterilisation and homogenisation units.
The basic unit consists of a sanitary product pump, a 316 stainless steel heat exchanger with a 304 stainless steel frame, an automatic three-way divert valve, a 15-30 s holding tube, a 100 l tank, a modulating valve for hot water and a stainless steel control panel with a temperature regulator and a paper recorder.
All these components are mounted on a 304 stainless steel skid.
All the parts in contact with the product are manufactured in 304L stainless steel and the equipment is TIG welded.
Optional extras include:
• Steam/water based hot water generation circuit.
• Product pump with variable speed drive, by means of a frequency converter inside the control panel.
• Automatic pasteurisation flow control with an electromagnetic flow meter and variable frequency converter.
• Electronic video recorder.
These units can be slightly modified to be used for the heat treatment of other products, such as pasteurisation of fruit juices and suspended solid-free milk-containing juices, pasteurisation and termisation of wine, pasteurisation of infusions, etc.
