A continuous frying device is for carrying out a frying process for food products. The device includes a frying oil reservoir which can be filled with a volume of frying oil; a food product carrier which can at least partially be immersed in the frying oil in the frying oil reservoir and at least one heating unit having at least one heating element which is positioned at least partially inside the frying oil reservoir and which has a heating surface which is in contact with the frying oil in the frying oil reservoir during the frying process. The filter chain has a first filter inside the frying oil reservoir and an external filter chain. In operation a volume of at least three times the volume of frying oil contained in the frying oil reservoir passes through the external filter chain per hour.

Traveling water screens including a non-metallic seal plate mounted to a face of a carrier chain link proximate a side portion of a basket frame are disclosed. The seal plate is configured to reduce flow between the chain link and the basket. Related methods of retrofitting a traveling water screen are also disclosed.
