Invention relates to a method and a device with high energy use efficiency and formation of a small amount of waste heat. A food product roasting device includes a roasting unit having longitudinal loading and unloading ends, an oil recirculation system connected to the roasting unit, a heat exchanger for oil heating in the oil recirculation system, an exhaust cabinet above the roasting unit for collection of steam generated during the roasting process, a pipeline for supply of steam from the exhaust cabinet and a steam compression compressor having an inlet hole connected to the pipeline and an outlet hole for compressed steam, which is connected to the heat exchanger. Versions of the food product roasting method include a heating stage of the oil returned to a repeated cycle from the roasting unit using the heat exchanger, to which heat of steam formed during roasting is supplied; a collection stage of steam generated during roasting in the exhaust cabinet above the roasting unit, a compression stage of steam in the exhaust cabinet under pressure exceeding atmospheric pressure; a stage of use of steam under pressure exceeding the atmospheric pressure. |

Method and device for food products deep frying Method for food products deep frying envisages supply of food products to be deep-fried into hot oil or fat and removal from such oil or fat upon expiry of a certain period of treatment. Over the free oil surface a steam-saturated zone is created containing superheated steam that protects oil from ambient air; a flow of steam corresponding to the quantity of water evaporated from the products being deep-fried is withdrawn from the zone; a border area is maintained between the steam-saturated zone and ambient air within the boundaries of a certain vertical area which results in almost complete exclusion of ambient air penetration into the steam-saturated zone with contact of the free surface of hot with ambient air prevented. |

Fire-prevention system of deep-fat fryer Fire-prevention system of deep fat fryer comprises a reservoir with fire-prevention reagent, pipeline joined to reservoir and one or more nozzles joined to pipeline and arranged to send fire-prevention reagent into frying container, when cover is not in fully opened position. When cover is in closed and unlocked position, it is possible to arrange nozzle outside of both cover and frying container so that fire-prevention reagent is diverted through hole into free space. |

Proposed roaster comprises a water vessel, oil vessel arranged above the latter for roasting with contact between oil and water. It includes also the heater arranged in oil vessel oil layer and oil feed pipe. Oil is forced by pump into water vessel bottom wherein roasting oil goes up through water layer to get into oil layer lower part. |

Apparatus for testing liquids quality in particular edible oil, cooking facility Apparatus comprises sensor designed with at least one pair of separated electrodes. Sensor is drowned into liquid for measurements. Electrodes and liquid measured form capacitive element with capacity changing depending on dielectric permittivity of liquid measured. Basically electrodes reach the same plane, and liquid surrounds both surfaces of electrodes from any plane side. Electrode is attached to substrate in such a way that liquid flows through plane. Sensor generates a signal that provides assessment of liquid quality. Apparatus can be connected to any cooking facility. |

Food product cooking apparatus comprising reservoir with thermally safe pouring device Apparatus has cooking reservoir designed for placing of cooking bath therein and equipped with pouring device for moving contents of cooking reservoir. Pouring device is adapted for moving contents of cooking reservoir into pouring vessel which may be detached from casing. Pouring device is further provided with thermostatic valve comprising temperature sensitive mechanical device movable depending on temperature to prevent contents from pouring out until temperature in cooking bath reaches predetermined threshold value, and to provide pouring out when temperature in cooking bath reaches predetermined threshold overturning value. |

Automatic machine for frying of doughnuts in fryer Automatic machine has accumulator communicating through dough feeding branch pipe with single semi-finished product dosing device adjoining to heat-insulated fryer bath wherein spiral heater is coaxially fixed. Automatic machine is further equipped with ready product extracting device comprising ejector and guiding rod connected to cutoff member of dosing device, which is movable in vertical plane relative to cup fixed in central opening formed in bath bottom. Dosing device is kinematically closed with stem for reciprocation drive disposed in dough feeding branch pipe. Valve partition is mounted in dough feeding branch pipe and fixed on stem of reciprocation drive mounted between stops of float-type dosing device. Cylindrical heat-exchanger is positioned within spiral of heater. |
