Annular space heat exchangers, such as the HRS AS Series, work by passing the product through the gap between the inner and outer tubes (the annular space), which makes them suitable for thick, highly viscous products such as fruit purees, thick sauces, honey and syrups. The advantage of such a design is that it ensures…

Directly injecting steam as a means of sterilising and diluting liquid drink products is a well-established technique for beverages such as plant-based milk products. Sales of vegan-friendly, plant-based milks have surged 10% over the past two years, and it is now the choice for almost 25% of Britons. In response to this increased customer demand,…

While heat treatment is important in ensuring the safety of apple juice through pasteurisation or sterilisation, for some products heat plays an important role in the production process itself. The physical and chemical properties must be considered when they are juiced and processed. Sugar content is typically around 11%, while dry matters vary between 13…

Normally the supply, installation and commissioning of a heat exchanger to sterilise food ingredients such as wort would be a relatively straightforward exercise, with HRS project engineers travelling from their bases in Spain or the UK to the client’s location. However, the travel and operation restrictions imposed globally by the Coronavirus pandemic earlier this year…

AHED (Advanced Heat Exchanger Design) is a powerful design tool for the calculation of one of the most used items of process equipment: shell and tube and heat exchangers (STHE’s). STHE’s are used in widespread process industries including Chemical, Oil & Gas, Wastewater, Food, Pharmaceutical & Automotive. The design of STHE’s is fundamental for a process…

Evaporation is a widely used industrial process. From the concentration of food products, to waste treatment and sludge management, evaporators are employed for a number of processes across many different industries. Accordingly, a number of different technologies, including heat exchangers, are employed across a wide range of industries. As a result, it is not always…

Modular process skids have become popular in the food industry due to their ease of transportation and installation. HRS Heat Exchangers has produced skid-mounted versions of numerous products and systems, for a wide range of applications including pasteurisation, cleaning in place (CIP), aseptic packing, heating, and cooling to name a few. What is a modular…

There is no doubt that disruptive technologies have the power to transform sustainability in the water sector, but it is important to realise that a technology does not need to be new in order to be disruptive. The widespread use of previously niche systems, or the novel use of well-established technologies like heat exchangers, can…

Heat exchangers are crucial to many processes in the water industry, in aerobic or anaerobic digestion plant, for cooling or evaporation, and for sludge concentration. Choosing the right heat exchanger can appear daunting, and maximising productivity is essential. WHAT IS PRODUCTIVITY? Productivity is measured by the ratio of output per unit of input. Many water…

HRS Heat Exchangers has created its unique R Series of rotating scraped surface heat exchangers from scratch to provide excellent heat transfer and performance. The range R Series of heat exchangers was designed without reference to existing types of scraped surface heat exchangers (SSHE). As a result, the HRS R Series of SSHEs boasts a…

There are numerous uses for heat exchangers in breweries, from cooling, pasteurising and fermenting products, through to efficiently dealing with waste streams such as yeast slurry. Compared to other methods of heating, heat exchangers can be much more energy efficient, providing both environmental and economic benefits. One of the first uses of heat exchangers in…

The UK is a nation of animal lovers, with 40% of households owning a pet. A quarter of UK households have a dog, and there are some 9 million canine companions around the country. Our feline friends are only just behind them with 7.5 million British cats¹. As a result, the UK boasts some of…
