Abstract

Described are dishes for preparing meals which are considered to be pots, casseroles, lids and fryers which is completed or filled with thermal insulation material (3) or is made from it.

Description

The technical solution relates to kitchen utensils for heating, cooking and deep-frying of foodstuffs, especially for household and restaurant transfers. The dishes for the preparation of this technical solution are pots, casseroles and deep fryers. They are also lids and openable and / or removable lids.

BACKGROUND OF THE INVENTION

The pots, saucepans and lids for cooking are made of several basic materials: steel sheet, stainless steel sheet, aluminum, cast iron or glass or other materials. These products either have no surface protection or are enamel-coated. The purpose is to protect the base material against corrosion. At present, technological protection is also used to prevent the content of heating and cooking from sticking to the surface of the container, or to prevent it from sticking to the surface. the aesthetic aspect is followed. No design or finish on prior pots, saucepans, or lids is intended to thermally insulate an internal substance that is heated or cooked in the container. Usually, the containers are heated from below, through the bottom of the container. Thermal energy is thus lost through the side walls and over the top.

Fryers are devices for preparing food by deep-frying, that is, by immersing them in hot oil. They can be divided into fryers for large-scale production (restaurants, crisps ...) and household fryers. Fryers for large-scale production are stand or table. The most important element of the fryer is the fryer. Made of stainless steel sheet. made of aluminum and is placed in a construction, a rack in which the controls and power supply. The heat spreads freely through the walls of the tray to the rack. It is the lost heat that the energy source must constantly replace. Household deep fryers are simpler and smaller. The tray may be separate or inserted into the housing. At the bottom of the tray is a built-in power source, usually electric. The trays themselves are not thermally insulated. A disadvantage of the prior art fryers is that there is a loss of energy due to heat leakage from the tray into the environment.

The essence of the technical solution

This disadvantage is alleviated by a technical solution based on thermal insulation applied in such a way that the pots and casseroles have all or part of the body wall, in addition to the bottom, fully or partially encased by the heat insulating material or are formed therefrom or . The thermally insulating material forming the walls of the pot can also be connected to the bottom by means of rings arranged in the form of an annular ring at its edge. The lid has a body provided on the outside with a heat insulating material. This material can be equally well arranged on the inside or the entire lid can be made of a heat insulating material.

The essence of the technical solution for deep fryers is that they have a tray made of or equipped with a thermal insulation material from outside or inside and the energy source is located above the thermal insulation material or the energy source is installed between the tray and the thermal insulation material. The opening and / or removable tray lid is attached to or made of another heat insulating material.

The purpose of the solution is to prevent heat leakage from food preparation containers and their accessories into the environment as much as possible, thus reducing energy consumption. It is a requirement that the heat insulating material is in particular a non-combustible material. For example, mineral wool or foam glass, or other material with low thermal conductivity, which resists heat, is suitable. In particular, the mineral wool layer must be protected against moisture and water. Then the protective jacket is designed. The thermal insulating property also has a vacuum The present solution achieves thermal energy savings which are all the greater the greater the cooling surface of the container.

BRIEF DESCRIPTION OF THE DRAWINGS

The present technical solution is shown in the following schematic figures, taken in cross-section in the central vertical plane, of which FIG. 1 shows a pot base body wrapped with a heat insulating material protected by a protective sheath. FIG. 2 shows a pot where vacuum is used as the thermal insulation material. FIG. 3 shows the heat insulating material inside the pot. Fig. 4 shows the base of the pot inserted into a roll of heat insulating material in which the cutout is made to the ear. In FIG. 5 shows a pot having walls of heat insulating material and these are fixedly connected to the bottom by means of a ring made of rings formed at its edge in the form of an annular ring. Fig. 6 shows the insulated lid

An exemplary embodiment

An exemplary embodiment of the invention is a cylindrical kitchen pot (casserole) made of a thermally conductive material, e.g. steel sheet of stainless steel sheet, aluminum, cast iron or glass or other materials. Its body 1 is wrapped with a non-combustible heat-insulating material 3, e.g. mineral wool. The thermal insulation material 3 is protected from mechanical damage and water ingress (during washing) by a sealing and mechanically strong outer protective sheath 4, e.g. Another embodiment is a pot (casserole) with double side walls between which there is a cavity 5 and there is a vacuum as an alternative to the heat insulating material 3. Another embodiment is a pot or casserole of conventional construction, e.g. made of foam glass or teflon, without additional outer sheath. Coats are also made where the heat insulating material 3 or vacuum is applied from outside or inside of the base body 1 of the cover. The fire and temperature resistance is reduced at all due to the greater distance of the lid from the heat source and in addition the lid is on the side facing away from the heat source. For these reasons, bakelite, teflon or other heavier combustible material from which the entire lid can be made may also be a suitable thermal insulation material. The object pursued - to achieve a reduction in the heat loss of the heated or cooked content is also achieved by producing the heat insulating material 3 as a hollow cylinder open at both ends, with an inner diameter greater than the outer diameter of the pot base 1 (casserole). bottom 2 to ears 6 pot or casserole. The pot or casserole is inserted into this cylinder and together they are placed above the heat source. When such a heat insulating material 3 is produced with a cut-out for the passage of the ears 6, the pot body 1 can be fully inserted into the heat insulating material 3. In the case of the development of non-combustible, sufficiently strong and light heat-insulating materials, also suitable for the purposes of kitchen containers, e.g. Teflon, only the bottom 2 with a ring of rings 7 arranged at its edge in the form of an annular ring can be made of thermally wild material, into which the side walls of the heat insulating material 3 are fixed. The design is suitable for electric and induction cookers.

An exemplary embodiment of a fryer for large-scale production is a fryer with a tray 9 made of metal. The thermally insulating material 3 is applied from the outside on the tray 9. It is applied to the entire outer surface of the thermally insulated tray 9, which is inserted into the rack 8, separated from it by the thermally insulating material 3. The tray 9 is covered from above by an opening lid 11. The lid 11 is top or bottom coated with a heat insulating material 3. In a variant embodiment, the lid 11 is entirely made of a heat insulating material 3.

Another embodiment of the fryer is the tray 9 provided with heat insulating material 3 from the inside. This is also applied between the tray 9 and the energy source 10.

In another embodiment, the energy source 10 is positioned between the tray 9 and the thermal insulation material 3.

Another exemplary embodiment is a deep fryer having an entire tray 9 made of a heat insulating material

Third

The household deep fryer has a tray 9 wrapped externally with heat insulating material 3 and is thus embedded in the sheath 4. The above embodiments can also be adequately applied to household deep fryers.

The operation of the fryer is generally known. The frying process takes place for a set time in a tray 9 filled with oil, which is heated by a source of energy 10 after filling.
