Abstract

Способ нагрева пищевых штучных полуфабрикатов на конвейере внутри туннельной печи, в котором их нагревают посредством их взаимодействия с разогретыми окружающими их газами с периодической или непрерывной подачей пара вовнутрь корпуса печи, отличающийся тем, что корпус печи выполняют в форме тонкостенной, прямоугольной в сечении трубы с длиной большей, чем размеры поперечника, которую размещают горизонтально и неподвижно, а конвейер выполняют в форме бесконечной, тонкой и термостойкой, плоской транспортерной ленты с приводом, прямолинейно движущийся участок которой вместе с полуфабрикатами направляют внутри трубы параллельно ей с небольшим зазором относительно ее внутренней нижней поверхности и с равномерными зазорами относительно внутренних боковых поверхностей, при этом полуфабрикаты нагревают разогретым окружающим их внутри трубы воздухом, разогретой внутри трубы транспортерной лентой и проникающим сквозь стенку трубы направленным инфракрасным излучением одновременно, нагревая поверхность трубы снаружи, снизу и с боков вдоль ее длины направленным на нее перпендикулярно инфракрасным излучением, одновременно измеряя в процессе нагрева температуру внутри трубы и поддерживая ее автоматически в заданных пределах, при этом наружную поверхность трубы сверху покрывают слоем термостойкой теплоизоляции. A method of heating food piece semi-finished products on a conveyor inside a tunnel furnace, in which they are heated by interacting with the gases surrounding them with a periodic or continuous supply of steam inside the furnace body, characterized in that the furnace body is made in the form of a thin-walled rectangular pipe with a length of larger than the dimensions of the diameter, which is placed horizontally and motionlessly, and the conveyor is in the form of an endless, thin and heat-resistant, flat conveyor belt with a drive, straight the moving part of which, together with the semi-finished products, is directed inside the pipe parallel to it with a small gap relative to its inner bottom surface and with uniform gaps relative to the inner side surfaces, while the semi-finished products are heated by the air surrounding them inside the pipe, heated by a conveyor belt inside the pipe and penetrating through the pipe wall directed infrared radiation at the same time, heating the surface of the pipe from the outside, from below and from the sides along its length directed towards it perpendicularly to infrared radiation simultaneously measuring the temperature in the heating process inside the pipe and maintaining it within a predetermined range automatically, and the outer surface of the pipe is coated from the top layer of heat resistant insulation.
