In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different. Understanding these properties ensures the correct heat exchanger is supplied. For example, high fouling materials may require a scraped-surface unit. Having adequate information will also ensure that the heat exchange process…

There is a lot of truth to the old saying ‘seeing is believing’. Trials are invaluable for assessing product quality parameters such as appearance or organoleptic performance, testing packaging designs and consumer research, producing samples for chemical or microbial analysis, or even assessing the feasibility of production or waste treatment. Buying dedicated equipment for trials…

Aseptic technology has become well established in the food and drink sector, yet some businesses are still unaware of its benefits or do not believe that it can be used with their products. In most cases, hot filling sterilizes the container as the product (which is still hot from cooking or sterilizing) is filled. However,…

A key challenge in the food industry is recovering valuable product which is left in equipment and pipework after production runs, for example between product change-overs and before cleaning. Product lost in this way increases operating costs unnecessarily and affects beverage manufactures to sauce producers, fruit and vegetable purées, and many other products. Companies often…

When treating wastewater, sludge and digestate, it can be beneficial to reduce the volume of material or increase the solids content. Mechanical dewatering via a centrifuge or belt press to separate solids and liquids is standard for the water treatment and anaerobic digestion sectors – but what if you want to further reduce the water…

Different materials need different types of heat exchanger. For the simplest fluids such as water and milk, plate heat exchangers are often sufficient, but as products become more challenging (for example more viscous, or containing particles), then different types of tubular and scraped surface heat exchangers are required.
