A fine mesh filter screen is used in the fry pot of a deep fat fryer to remove all but the finest loose food particles after every cooking cycle, which otherwise burn and shorten the life of the cooking oil.

The unit features a metal inner casing within which a deep pan is located, containing a mixture of oils heated, a drainer moving on a horizontal axis, and guiding means for conveying a portion of raw food towards the drainer, which is immersed in the oil mixture, the inner casing being fitted with a window mounted in a door that opens towards the outside of the inner casing, through which the drainer moves, enabling the fried food to be unloaded into a container located in a station that is accessible from outside the unit, and being kept under the action of a depression by a suction means, upstream of which is fitted a means for purifying the greasy fumes given off by the oil.

Apparatus for cooking food in a convention oven having a conveyor includes a ventless exhaust system in which a fan pulls heated air through a filter system including an aluminum filter, an electrostatic precipitator and a charcoal filter. Cleaned air may be recirculated within the building space in which the oven is located.

An automatic noodle cooker which continuously and automatically supplies hot water while cooking long thin ingredients such as spaghetti. The noodle cooker comprises a hot-water boiler which is divided into several water storage spaces, for example four, and which allows the supplied water to flow from space to space, and where each storage space is equipped with its own heater. The water supplied to the first storage space is heated by the heater and then moves to the next storage space. The hot water is finally supplied from the last storage space through a hot-water supply pipe to a processing section where the ingredients are processed. If new water is supplied to the first storage space equal to the amount of water which was supplied from the last storage space, the temperature of the hot water in the last storage space does not drop very much due to the fact that there are several storage spaces. Therefore, hot water can be continuously and automatically supplied to the processing section from the last storage space at a constant temperature, thus making it possible to improve the processing efficiency of the ingredients. Also, By using a high-pressure pump to supply hot water, the temperature of the hot water can be increased, improving the processing efficiency even more.

Apparatus for cooking food includes a ventless exhaust system whereby a fan pulls heated air through a filter system which includes an aluminum grease filter, an electrostatic precipitator, a flame arrester and a charcoal filter. A fire extinguisher is also included. Cleaned air may be recirculated within the building. The apparatus may be operated either as an open-faced, unpressurized fryer or as a pressurized or semi-pressurized fryer.
