An infrared dehydrator unit for minced fish to produce an edible fish product. The unit is constituted by a gas-fired infrared heater provided with a refractory body having a radiation horn from which infrared rays are projected into the interior of a tank containing a load of minced fish to be dehydrated. The tank is provided with an agitator acting to pick up and expose all pieces of the load to the rays to effect dehydration thereof. The radiation pattern of the horn is such as to confine the projected rays to the exposed pieces of the load and to avoid striking and heating the sides of the tank. In this way, scorching and sticking of the agitated pieces when they make contact with these side walls are prevented. As a consequence, the dehydrated pieces are of substantially uniform quality and waste thereof is obviated.
