Frying is performed in two stages so as to dip a retainer in frying oil at a prescribed dipping ratio and then to dip the whole of the retainer in the frying oil, and in addition, flow rates of the frying oil supplied from an upstream side and a downstream side of a frying oil tank and a surface level of the frying oil are controlled. Therefore, a noodle lump can be prevented from peeling off and floating from the bottom of the retainer before fixing the shape of the noodle lump due to a pressure applied by the frying oil so as not to impair the shape of the noodle lump, and as a result, frying efficiency or production efficiency can be improved. Besides, a noodle lump that has a very small number of coarse or dense portions in a distribution of noodle strings can be stably produced.

A metal heat exchange tube assembly for a fryer cooking channel of a hot oil fryer for food-process lines has a plurality of elongate, rectangular, longitudinally-extending heat exchange tubes with open inflow and outflow ends; a laterally-extending abbreviated rectangular inflow-manifold tube with a plurality of apertures in a sidewall; and a laterally-extending abbreviated rectangular outflow-manifold tube with the same. The plurality of heat exchange tubes are joined to the inflow-manifold and outflow-manifold tubes with respective alignment among the open ends of the heat exchange tubes and the apertures in the sidewalls of the manifold tubes. The heat exchange tubes comprise a composite construction of an elongate, square-U shaped channel having a web bottom wall and flange sidewalls of a given uniform thickness, and an elongate closure strip welded along spaced seams to the exposed upper edges of the flanges of the channel, thereby forming a thermal oil conduit.

A heating device for heating a liquid includes at least one infrared heat source, such as an infrared lamp, accommodated in a corresponding casing of a heat conducting material. The heating device furthermore includes a conduit of a heat conducting material, where the conduit has an inlet and an outlet and where liquid to be heated in use flows through the conduit from the inlet towards the outlet. The conduit is wound spirally around the casing of the infrared heat source to facilitate, in use, the emission of infrared radiation by the heat source through the casing and the conduit into the liquid flowing through the conduit so as to heat the liquid.

A frying oil and/or frying fat sensor (1) for determining a frying oil and/or frying fat quality, having a conductor structure (2) that is fixedly connected, at a proximal end, to an electronics part (5), wherein the conductor structure (2) has an inner conductor (6) and an outer conductor (7) that are arranged coaxially with respect to one another and are both connected fixedly to the electronics part at the proximal end. The inner conductor (6), at at least one free end, is guided so as to be able to move relative to the outer conductor (7) in the axial direction in order to compensate temperature-induced mechanical stresses.

A batch fryer for kettle manufacturing of deep fried food stuff comprising: an elongated cooking trough for holding a volume of cooking oil; an infeed provided at an infeed end of the elongated cooking trough for receiving food stuff; an oil circulation system comprising an oil inlet circuit and an oil outlet circuit connected to the trough for recirculation of the cooking oil in the trough; a circulation pump configured to pump oil through the oil circulation system; a heat exchanger connected to the circulation system configured to heat the cooking oil flowing through the heat exchanger from the oil outlet circuit to provide heated cooking oil to the trough via the oil inlet circuit; a booster oil inlet circuit connected to a booster pump configured to pump heated cooking oil into the trough through a booster oil inlet arranged in a wall at the proximal end of the trough at the beginning of a batch deep-frying process of food stuff.

An automatic cooking system is provided to reduce and/or optimize the amount of cooking medium required to operate the fryer, while improving the temperature and flow characteristics of cooking medium in the fryer. To this end, the cooking vat of the system is designed with one or more heating elements and one or more lanes for flow of cooking medium and food products between inlet and outlet ends, with the heating elements defining a low profile and/or being mounted externally to the cooking vat to avoid impeding flow of the cooking medium. One example of such a heating element is a printed heating element that is coupled to or directly printed on the cooking vat. This arrangement reduces the total volume of retained cooking medium needed to flow and move food products along a length of the cooking vat during a cooking process.

A cooking vessel for a cooking system is provided that includes a table including a longitudinal axis, a first end, a second end opposite the first end, a trough positioned along the table that is more proximate the second end than the first end. The cooking system further includes an inlet header positioned at the first end that is configured to emit cooking fluid onto the table such that the cooking fluid is to flow across the table toward the trough, and a plurality of oil nozzles positioned along a base of the table, wherein each of the plurality of nozzles is configured to emit oil along an upper surface of the base toward the trough.

The present invention relates to a processing apparatus, in which a flying oil is heated, disinfected and/or pasteurized, sterilized. The present invention further relates to a method to treat a flying oil with radio-frequency wave

A frying oil and/or frying fat sensor (1) for determining a frying oil and/or frying fat quality, having a conductor structure (2) that is fixedly connected, at a proximal end, to an electronics part (5), wherein the conductor structure (2) has an inner conductor (6) and an outer conductor (7) that are arranged coaxially with respect to one another and are both connected fixedly to the electronics part at the proximal end. The inner conductor (6), at at least one free end, is guided so as to be able to move relative to the outer conductor (7) in the axial direction in order to compensate temperature-induced mechanical stresses.

An apparatus for frying snack foods, the apparatus including a fryer having a tubular frying section with inlet and outlet ends, the outlet end downstream relative to the inlet end. An oil supply system for supplying oil to the inlet end. A food input at the inlet end adapted to introduce pre-fried snack food pieces into a flow of oil at the inlet end. A food output at, or downstream of, the outlet end adapted to separate fried snack food pieces from the flow of oil. An oil flow accelerator accelerating oil flow from the inlet end to the outlet end thereby conveying the snack food pieces, immersed in the oil, from the inlet end to the outlet end during a frying process. Also disclosed is a method of frying snack foods.
