A compact and complete pasteurization solution

Pasteurization and sterilization are widely recognized as being among the most effective and efficient processes to reduce or remove microbes from food and beverage products, ensuring product safety, preventing spoilage and waste, and increasing shelf life.

Although the basic premise of pasteurization and sterilization is simple – heating the product to a specified temperature for a specified time – in practice other elements such as heating the service fluid, rapidly cooling the product after pasteurization, and maintaining aseptic conditions all need to be considered.

This means that while the actual pasteurization process can be performed efficiently and effectively by a single corrugated tube heat exchanger model (the choice of which will depend on the nature of the product), other elements such as additional heat exchangers, or the ability to recover and reuse heat to maximize energy efficiency, can quickly add size and complexity to even a simple pasteurizer.

 
All-in-one pasteurization

The range of HRS Thermblock Series pasteurizers and sterilizers are purposely designed to provide a convenient packaged solution for the pasteurization or sterilization of food and drink products ahead of further aseptic filling or any other packaging method.

Based on HRS Heat Exchangers’ proven range of corrugated tube heat exchangers, The HRS Thermblock Series is available with annular space (AS Series), double tube (DTA Series), or multitube (MI Series or MR Series) heat exchangers. All HRS Thermblock Series allow for the adjustment of the heating and cooling cycle of the product, and are ideally suited to HTST (High Temperature, Short Time) pasteurization and sterilization.

Often skid-mounted for easy installation, depending on configuration the HRS Thermblock Series can be designed to directly or indirectly recover as much as 90% of the energy for reuse, greatly reducing overall energy consumption and significantly reducing payback period. Depending on the model chosen, the HRS Thermblock is suitable for a wide range of products from simple juices and sauces up to products containing large particles, such as diced onions and tomatoes, fruit dices, etc.

 
For those looking for a packaged pasteurizer/sterilizer and aseptic filler the HRS Asepticblock and HRS Asepticblock Mini are also available, combining all the benefits of the HRS Thermblock with high capacity HRS AF aseptic fillers which are suitable for a range of liquid and pulp-type products.
