Apparatus and method for heating frying oil with solid-state RF energy technology

Processing apparatus, in which a product is transported by a transport means and is fried in a frying oil chamber comprising frying oil,

• wherein the frying oil is pumped by a pump in a flow direction through a microwave chamber and is thereby heated,
• wherein the microwave chamber is provided as a tube, the microwave chamber comprises at least one solid-state radio frequency source,
• wherein the frying oil is configured to flow out of the frying oil chamber towards the microwave chamber where the frying oil is heated and then the frying oil is configured to flow back into the frying oil chamber,
• wherein the flow direction of the of the frying oil in the frying oil chamber is the same as a flow direction of the product that is transported by the transport means,
• wherein the processing apparatus comprises a filter in the tube of the microwave chamber, and
• wherein an amount of energy generated by the at least one solid-state radio frequency source to heat the frying oil depends on a desired temperature of the frying oil.
