HRS Double Tube Pasteurizer / Sterilizer

The HRS Thermblock DTA Series is a packaged double tube pasteurizer and sterilizer for food products containing pieces or particulates, for aseptic filling processes or any other filling/packaging method. The sterilizer is composed of double tube corrugated heat exchangers from the HRS DTA Series that are the most suitable heat exchangers range for fruit dices.

HRS Thermblock DTA sterilizers allow the adjustment of the heating-holding-cooling cycle of the product to suit your product and method of working. It can also work as an HTST (High Temperature, Short Time) unit, able to bring the product under high temperatures for a short time.

As it is designed to handle delicate products and fruit pieces, the sterilizer includes an HRS BP Series piston pump. This is a positive displacement pump that was originally designed for fruit dices applications and was found to be suitable also for viscous products and products with large particles.



The sterilizer can optionally feature reception, air-removal and product impulsion sections which helps ensure the absence of air during the thermal treatment stage.

The HRS Thermblock DTA Series is suitable for:

  • Tomato dices
  • Diced onions
  • Fruit dices (peaches, apricots, strawberries, pears, apples, etc.)
  • Products with large particles
  • Soups and sauces with pieces or particulates
  • Baby food with pieces or particulates
  • Jam and marmalades with particulates
