The FlowJet HPM Microwave Flow Steriliser was created for companies that, as part of their pasteurisation and sterilisation processes, want to use the recognised and efficient thermal processing methods, to guarantee certainty and reliability while simultaneously maintaining high quality in all product parameters.

Owing to the patented Direct Energy Transfer (DET) technology, which allows the instant and direct transfer of energy to a flowing substance, we have solved the issue of maintaining the best standards in the quality and parameters of those products subject to thermal processing, reducing the process time to barely a few seconds and eliminating undesirable adherence of the product to the walls of the exchanger.

The FlowJet HPM steriliser combines all the undisputed advantages of the UHT method, simultaneously meeting and maintaining the highest requirements regarding the quality and parameters of pasteurised products.

Conventional pasteurisation methods consume a lot of time and energy because they require large heating surfaces and a separate heating media, such as steam or hot water. The start-up of a conventional pasteurisation line involves the time and energy required to heat or receive such media. However, for microwave technology the energy is delivered directly to the water particles without any contact with heating elements, which means we only expend the energy when it is required to heat the product.

The heating part consists of a short section of smooth pipe, which presents almost no resistance to the product. The pipe is made of Teflon (PTFE), which further enhances the low adhesion qualities. The product does not adhere to the walls during the pasteurisation process, which guarantees the cleanliness of the system. Since the energy is transferred by microwaves, the heating system has minimal inertia and is ready to function almost immediately after activation.


The use of membraneless microwave energy transfer eliminates the problem of thermal decomposition as well as losses in the quality and other parameters of the product by contact with the hot walls of the exchanger. A large amount of energy can be immediately delivered to a flowing product, heating its entire mass in a very short section of pipe. As a result, the product exposure time has been reduced to the absolute minimum.

Significantly, the density, viscosity and homogeneity of the product are of no major importance for the heating process. This technological solution works as well in sterilising juices, concentrates, syrups, pomaces and dense masses.

The fundamental element is the HPM heating module, which consists of a magnetron resonance chamber. Through this chamber passes a pipe made of pure PTFE (Teflon), with a special fastening system to ensure hydraulic sealing and electromagnetic shielding. The simplicity and small dimensions of the modules allow them to be adjusted to suit the type of media, heating power, capacity, etc.

Regardless of the number and type of heating modules, they are all managed by an automatic control system to achieve precise monitoring of the process parameters.


For the smallest applications we offer the FlowJet Compact Steriliser, with a capacity ranging from 90 l/h to 390 l/h. This is a complete device, fully automated, fitted with its own pump, heat recovery and cooling exchangers, as well as a control panel. It is designed for work with any low-capacity batcher or packaging line.

Equipment for in vitro laboratories

ENBIO Technology Sp. z o.o. has its origins in Vitroservice Sp. z o. o., whose principal activity was in vitro plant production for leading plant raising laboratory companies in the Netherlands and Germany. Over a 20 year period it delivered over 100 million plants, meeting the required high quality standards, ensuring reliability and continuity of supply, even for the largest orders. Such operations required the continued improvement of the processes used at Vitroservice, which resulted in the invention and production of a world-unique media sterilisation device, the FlowJet Microwave Flow Steriliser.
The great results we achieved thanks to FlowJet encouraged us to share this innovative solution.
The FlowJet Microwave Flow Steriliser sterilises the flowing media with the use of the innovative Direct Energy Transfer (DET) method.
This method simply and quickly sterilises the media without the risk of burning and decomposing any of the ingredients.

The main advantages in comparison to traditional sterilisers are:

  • The potential for flexible increases in capacity of up to 400 l/h
  • Energy savings – 75% in comparison to autoclave sterilisation and 50% with a media preparer
  • Time savings
  • Ease of use
  • Limited exposure of the media to high temperatures – the sterilisation takes only a few seconds
  • Agar use reduced by 30%
  • 100% microbiological efficiency

FlowJet microwave autoclave

FlowJet can also be used as flow autoclave for difficult media. It allows the sterilisation and pasteurisation of dense products, for which other methods (such as UHT technology) fail to guarantee a stable process temperature for the entire mass flow. In addition, another huge advantage is that the exposure time at high temperatures is several times shorter than with other technologies.
