A method for thawing frozen foods by recycling the water that is used to thaw the frozen foods. Food is first placed inside of a container and then water is pumped from the bottom of the container where the water is heated and by use of a pump and natural rise of heat allowed to flow around the food. When the water reaches the top of the container, it spills over the top and is pumped back into the bottom of the container as a continuous process until the food is thawed.

A revolutionized tuna process according to this invention generally comprising the steps of thawing of frozen tuna, de-heading and degutting, fileting, de-skinning, cleaning of the de-skinned tuna filet, pre-cooking, cooling, packing of the cleaned and pre-cooked tuna loin, and sterilizing the packed tuna loin or freezing the tuna loin. Not only does the process according to this invention reduces the energy utilization by half, it also significantly reduces the time required for cooking and cooling. Therefore, the whole processing time is significantly reduced from at least 8.0 hours in the conventional process to less than 30 minutes.

A rapid, uniform and high-quality thawing method is awaited which is free from a burn and boiling and which is indispensable for a freezing technology that is frequently used in the fishery industry and the fishery processing industry. For rapid thawing, electromagnetic waves of 130 to 300 MHz in which a B zone passage required time serving as a rate limiting step is decreased are utilized, for uniform thawing, electromagnetic waves of 110 to 170 MHz are utilized and in order to prevent boiling and a burn in the application and after the thawing, electromagnetic waves of 110 to 160 MHz in which a temperature increase after the thawing is decreased are utilized, with the result that the corresponding problems can be solved.

By preheating temperature raising unit of a steam and hot water generating device beforehand to a predetermined temperature, and supplying water in an amount equal to or more than predetermined amount V (per unit time) to the temperature raising unit, a large amount of steam is instantaneously generated. At this time, hot water adhered to the temperature raising unit rises along with the steam, and the steam and hot water flowed through a steam hole, a relay tube, and a steam chamber are caused to eject instantaneously with accumulated steam pressure from a steam and hot water discharging port. The steam and hot water then hit and heat food products accommodated in a cooking chamber. Thus, a heating cooker capable of promptly heating a food product with steam can be provided.

To minimize the frequency of losses in the form of product tailpieces, which cannot be sliced because of gripper claws located therein, long or endless products are produced, whether outside or inside the cutting machine, by positioning product parts adjacently in lengthwise direction one behind another and joining mutually facing end faces of these product parts. The product parts may be joined outside the machine, resulting in long but finite products, or by positioning within the machine and on a feed belt a new product part in each case in succession at the rear end of the product currently being sliced and joining the new product part to the rear end of the rearmost product part of the previous product to form a virtually endless product.
