RU2120757C1 - Bakery oven - Google Patents

Abstract

FIELD: dough baking equipment. SUBSTANCE: bakery oven has chamber with door, car with pans and convective heating system. Oven width is reduced due to attachment of car strip to its front poles, and rear poles are positioned at outer side of strips, with pan size being standard. Inner walls of working chamber may be provided with two projections allowing symmetrical mounting of car in chamber and direction of air flow. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 1 dwg

Description

 The invention relates to equipment for the food industry and can be used in the manufacture of bakery convection ovens.

 Known bakery oven containing a working chamber with a door, a rotating trolley with baking sheets and a convective heating system (see description of the invention to the autosweet USSR N 1743529 according to class A 21 B 1/22, publ. 30.06.92, bull. N 24).

 The closest invention to the claimed technical essence and adopted as a prototype is a baking oven, which contains a working chamber with a door for loading and unloading, carts with trays with dough pieces laid on them and a convective heating system (see German Patent No. 4122847, cl. A 21 B 3/04, publ. RJ ISM 3-04-94).

 A common disadvantage for the known analogue and prototype is the manufacture of bakery ovens with increased overall dimensions in width.

 The present invention solves the problem of reducing the width of the oven while maintaining the standard dimensions of the baking sheets and without violating the technological regimes of baking bread.

 To solve the technical problem in the patent oven for baking, along with similar features of the prototype - this is the presence of a working chamber with a door, trolleys with baking sheets placed on shelves and stacked on baking sheets with dough pieces, there are new signs that are different from the prototype, providing a reduction in size oven, it is that the shelves of the cart are attached end-to-end to its front racks, and the rear racks are installed on the outside of the shelves so that the outer sides of the front racks are located They are on the same lines as the inside of the rear pillars. In the working chamber on its inner walls in the front part two protrusions can be made for symmetrical installation of the trolley in the chamber and for the direction of air movement.

 The presence in the present invention of a new set of essential features in comparison with the prototype of new structural connections between the racks and shelves of the trolley allows you to reduce the width of the baking oven using standard sizes of baking sheets, which provides the invention with the condition of its patentability "novelty".

 An analysis of the baking oven claimed for patenting in comparison with other well-known technical solutions in the food and baking industry allows us to conclude that there are no signs inherent in the claimed oven, and therefore, the baking oven meets the second condition of its patentability - "inventive step".

 The implementation of the baking oven can be carried out in the food industry, as well as in bakeries or bakeries when baking bread and any dough semi-finished products, and therefore the baking oven is industrially applicable.

 In FIG. Shows a horizontal section of a baking oven with baking sheets on a trolley and stacked dough pieces.

 The bakery oven consists of a working chamber 1 with side inner walls 2, doors 3 for loading and unloading the cart 4 with baking sheets 5, a system 6 of convective heating and air recirculation. The trolley 4 has front racks 7 and 8 and rear racks 9 and 10, shelves 11. In the front of the inner walls 2 of the working chamber 1, protrusions 12 can be made, shelves 11 are attached end-to-end to the front racks 7 and 8, and the rear racks 9 and 10 carts 4 are installed with the approach from the outer side of the shelves 11 so that the outer sides of the front racks 7 and 8 are located on the same lines with the inner sides of the rear walls 9 and 10, Dough pieces 13 are placed on the baking sheets.

 Since furnaces can be manufactured with and without protrusions, the protrusion in the figure is shown on one side.

 On the trolley 4, the baking sheets 5 are installed with the dough pieces 13 laid on them, and the loading of the baking sheets 5 on the shelves 11 is carried out from the side of the rear racks. After loading the trolley 4 into the working chamber 1, preheated to a predetermined temperature, close the door 3, turn on the convection heating system 6 and hot air recirculate in the working chamber 1, passing between the inner walls 2 of the chamber 1 and the outer part of the trolley 4 and blowing pastry dough pieces from all sides. After the baking process is completed, the recirculation system 6 is turned off, the chamber door 3 is opened, the trolley with finished products is unloaded from the chamber, and another trolley is loaded in its place with the dough pieces laid on its baking sheets.

 The process is repeated.

 Compared with the prototype of the inventive baking oven has a smaller overall dimension in width using baking sheets of standard sizes.
