A food product sterilizer includes a food product source and a regenerative heat exchanger configured to receive a flow of food product from the food product source. The heat exchanger includes an input channel configured to receive a flow of food product to be sterilized. The heat exchanger also includes an output channel fluidly coupled to the input channel. The output channel is adjacent the input channel. The output channel and the input channel are configured to transfer heat between the two channels. The heat exchanger further includes an integrated heating section of at least a portion of the input channel or the output channel. The heating section is configured to heat the flow of food product.
