(54) DEVICE FOR HEAT SHEAR PROCESSING

one

The invention relates to the field of public catering and can be used in everyday life.

A device for the heat treatment of kebabs is known, comprising a frying chamber, inside which are mounted rotatably holder with spits, a heating element and a pan for fat 1.

In the known device, the shish kebab is heated only from above, the rest of the product is brought to readiness due to the thermal conductivity of the meat, which increases its cooking time. The latter leads to a decrease in the quality of the products, since the surface of the product is exposed to infrared rays and high temperature all the time until the inside is ready.

The aim of the invention is to reduce the heat treatment time.

To achieve this goal, a heat treatment device contains a frying chamber, inside which are mounted rotatable holders with spits, a heating element and a fat pan, according to the invention, the spit is made in the form of a heat pipe, the internal cavity of which is filled with high-boiling heat carrier 20-25%, and set at an angle of 5-10 to the horizontal.

FIG. 1 shows the device section; in fig. 2 shows a section A-A in FIG.

The device contains a frying chamber 1, inside which is installed

Claims (1)

10 a holder 2 with spits 3, a heating element 4, a pallet for grease 5. Loading and unloading takes place through the doors 6. The holder with spits can be rotated using the handle 7. Each spit is made in the form of a sealed tube and pointed at one side of the tube. After the preliminary evacuation of the tube, the cavity of the tube is filled with 20–25% high-boiling organic coolant, ditolylmethane. To improve condensate flow to the skewer heating zone, they have a slope of 5-10 ° to the horizontal. The end of the skewer, where the heat carrier is concentrated, is heated by infrared rays simultaneously with the upper layers of the product. An isobaric-isothermal process of evaporation and condensation takes place in the cavity of the skewer. Pred30 vacuum creasing allows this process to be carried out at the required temperature level (80-150 ° C and above: e) in accordance with the technological requirements. The device works as follows 66. They are strung on skewers 3, which are fixed on holders 2 and placed inside the frying chamber 1. The heating element 4 is turned on. The infrared rays heat the product and at the same time the skewer of the heat pipe where the heat transfer agent is located. In the heating zone, evaporation of the coolant occurs, and vapor condensation in the heat sink zone, i.e. in the zone where the product is located. Thus, the product is subjected to heat treatment simultaneously from two sides: from the outside by infrared rays and from the inside by the heat of the condensing coolant vapor. These designs of the skewer, as shown by experiments on the layout model, reduce the heat treatment time of products by 5-10%. The invention of the device for the heat treatment of kebabs containing a frying chamber, inside of which are mounted rotatably holders with spits, a heating element and a pan for grease, so that, in order to reduce the heat treatment time, each spit made in the form of a heat pipe, the internal cavity of which is filled with high-boiling coolant by 20–25%, and installed at an angle of 5–10 ° to the horizontal. , Sources of information taken into account during the examination 1.
