Ohmic heating
Alflow sells customised Ohmic heating systems for sanitary applications. Explore our different Ohmic systems on this page.
Ohmic heating: efficient, precise and gentle heating
Ohmic heating is an advanced thermal treatment where food acts as an electrical resistor and is heated by conducting electricity through it. Electrical energy dissipates into heat, resulting in rapid and uniform heating. Ohmic heating is also known as electrical resistance heating, Joule heating or electro-heating and can be used in a wide range of applications in the food industry.
Ohmic heating can be used for heating liquid foods containing large particles and other heat-sensitive liquids, as well as for processing protein foods that tend to denature and coagulate when heat-treated. For example, Ohmic heating is suitable for:
- Supper
- Stews
- Sliced fruit in syrup
- Saucer
- Cream cheese
- Juice
- Liquid eggs
- With more
Ohmic heating offers several advantages over traditional heating with hot water and steam. As there are no hot surfaces for the product to burn on, you achieve gentle and uniform heating. Ohmic heating also provides short heating times and a homogeneous temperature throughout the product, even with particles. Another advantage is extremely precise temperature control - even with varying flow rates. This results in very high efficiency and a high degree of effectiveness.

At Alflow, we also want to deliver the best systems on the market. You can see this in the fact that our models are extremely durable, as they are produced in the most suitable material in terms of application possibilities. When you buy an Ohmic heater from Alflow, you get a long-lasting solution.
Ohmic heating can be used to heat liquid foods containing large particles, such as soups, stews, sliced fruit in syrup, sauces and other heat sensitive liquids. The technology is useful for processing protein-containing foods that tend to denature and coagulate when heat-treated. For example, liquid eggs can be heated ohmically for a fraction of a second without coagulating. Juice can be treated to inactivate enzymes without affecting the flavour. Other possible applications of ohmic heating include blanching, thawing, fermentation, peeling, dehydration and extraction.
In Denmark, ohmic heating is used in the production of dairy products, including cream cheese. A number of plants around the world produce soups and fruit, among other things. In the US, ohmic heating has been used to produce a product with large particles and low acidity, as well as pasteurised liquid eggs. In general, any product can be analysed for the possibility of using ohmic heating.
