'electric pen' "clever"

The invention relates to equipment for heat treatment, in particular for frying food products and maintain them in the hot condition and can be used at home and at public catering enterprises

Closure for frying pan has casing and handle. Openings provided in upper part of casing are extending from casing center to its peripheral parts. Closure is equipped with one or more blades, which are fixed at an angle to casing thereon by means of pivot joint so as to define an angle with frying pan bottom. Blade is provided with shank abutting against casing for ensuring predetermined angle of inclination. In order to change position of blades relative to casing and, correspondingly, position of frying pan, closure may be provided with control device adapted for wedging of blade relative to casing. One of versions of said control device is wedge which may be fixed on arm rotating relative to axis of handle, said wedge being driven by means of lever rigidly connected to wedge. Any device identical to wedge may be used provided that said device has cylindrical or spherical working surface.

Invention relates to appliance for pan designed to protect range, kitchen room and utensils and also personnel working in kitchen from boiling fat sprays. Proposed replaceable filtering holder for pan consists of three perforated disks interconnected over edges by ring gaskets providing required air gap between disks. Perforation of disks is made in form of round holes arranged in rows with intervals between rows equal to diameter of holes. Disks are installed so that rows of holes in all three disks are parallel to each other. Rows of holes in first and third disk coincide in vertical, and rows of holes is second disk are displaced relative to the latter through value of interval. Disks and ring gaskets are made of corrugated cardboard. One of sides of all three disks is covered with aluminum foil. Foiled surfaces are pointed to one side, and nonfoiled surfaces, to opposite side. Filter made on nonwoven synthetic material impregnated with activated carbon is placed in one of clearances between two adjacent disks.

Improved frying pan has reservoir for oil collection separated from area of food products frying by grid, which is movable and detachable to make it possible to clean internal side of specified reservoir. Grid has upper area with openings of larger diameter and lower area with smaller diameter openings that act as filter of admixtures. Frying pan has mark that indicates maximum level of oil, which may be held by reservoir.

Invention relates to the container for food preparation with means of temperature indication. The container for food preparation contains structural components located outside of the main casing of the container. Detachable label with covering containing thermal chromatic pigments is applied to the components. Also the labels are detachable, have different configuration at that different temperature sensibility of the pigments corresponds to each of these configurations.

Multilayer bottom of the reservoir is used in the production of the dishware for high-temperature processing of food products. The bottom consists of two fixedly connected layers made of different materials motonically increasing from the center to the periphery. The contact line is made in the wavelike amplitude and the ratio to the wave length. Besides the maximum wave amplitude doesn't exceed 0,1-0,3 of the thickness of the most thin layer. The method of multilayer bottom production includes the connection of different materials by explosive welding. The driver material is made in the form of asymmetric rotary shell segment which axis is set perpendicularly to the fixed plate. The crowned surface of the shell turns to the fixed plate. Then the materials are connected with the explosive material layer posed on the concave surface of the layer with further activation in the center. Curve radius is defined according to the set ratio: where K - curve radius of the shell, a - angle between the axis and shell normal, r - interval between the center of the fixed plate and its crossing point with the normal, 5 - shell thickness, X - wave length of the welding seam in the distance from the center of the plate, and II are quickness of an explosive and the shell in the crossing point with the normal.

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.
