Description

Furnaces for smoking food products with a separate firebox and with a number of obliquely arranged beds and shelves for moving the processed material are known. In the proposed invention, related to the type of furnaces, in order to process the product under various conditions, the shelves for moving the trays are located directly below the alternating slopes in different directions of the stoves, equipped with doors and a chimney with windows that close the flaps.

In FIG. 1 shows a longitudinal section of the furnace; FIG. 2 is a front view of the furnace, partially cut, and FIG. 3 is a section along line AB in FIG. one.

The furnace has a chimney 20 located above the furnace 1 (Fig. 2 and 3) with two windows with flaps 2 and 12, a pipe 11, also equipped with two windows with flaps 13, 10, and four Russa 3, 5, 7 and 9 with doors 4 , 6, 8, 15 and 18. For the installation of trays with the material serve lolozki 16 (Fig. 1).

The furnace can be operated by means of direct or reverse flow of gases. According to the method of direct flow of gases, fuel is burned at the grates of the furnace 1; the products of combustion are sent via a window with a flap 2 into the first Russian 3 of the furnace (lower); then, at the door 4, they pass into the second Russian 5, at the door 6 they get into the third Russian 7, and finally, at the door 8 they get into the fourth; from where through the open valve 10 are thrown into the pipe 11. With this method of heating, the valves 2 and 10 are open and the valves 12 and 13 are closed. By the method of reverse current, with the shutters 2 and 10 closed and the open arms 12 and 13 closed, the combustion products rise through the chimney 20 and through the damper 12 enter the fourth rus from where the third and second rushes down and finally are thrown out the valve 13 into the pipe 11. The furnace is loaded and further replenished with the material being processed as follows. The baking sheets of one type or another with the processed product (fish, fruit, etc.) through the door 15, with the damper 10 open (so that the stove does not smoke), are placed one by one on the polozok 16. did not go astray from the runners 16, the trays provided with guide corners. Thus, gradually, the fourth rus is filled with loaded baking sheets. Then the front trays through the door 8 are manually pulled off from the fourth rusa skids and set, gradually moving forward, to the third rus poloski. Subsequently, this operation is performed with the front plates at the doors 6, where they are transferred to the poloski of the second rus and further, through the door 4 to the poloskas of the first rus, from which, finally, through the door 18, the finished product is removed from the oven finally. As the front trays move toward the exit, from the oven, through the door 15, new trays are replenished.

If the valve 10 is supposed to be closed by the received process, then it should be opened (so that the stove does not smoke) only during the replenishment of the stove with new pans. The method of direct flow of gases is used in the case when it is meant to process a material with a low water content, which is very gentle and does not allow to produce much heat. They operate on a weak flame with considerable precautions. The reverse current is useful if the material contains a lot of water and the firebox has to be forced to force to ensure the proper intensity of the process. There may be cases of combined work, i.e. when part of the work is done directly, part of it is reverse current. The furnace can be used in fisheries and in the processing of garden, garden and field household products (drying, etc.). Due to the consistent transition

All the furnaces under the constant Hall were observed by the operating personnel, and the danger of getting so-called material steaming disappears, which is very important, because even in the best rotary drying ovens this danger is considerable, especially for some of them. sections where the amount of heat and temperature of the process are not in accordance with the amount of moisture in the material being processed and the process conditions contribute to the development of microbiological processes causing a significant decrease in / about sugar I in the dried fruit and putrefaction in the fish and meat products .

The subject of the patent.

A furnace for smoking food products with a number of obliquely arranged beds and shelves for moving the material being processed, with a separate firebox, characterized in that the shelves 16 for moving the trays with the material are located directly below the alternately inclined ne; stoves of the furnaces, which are equipped with doors 4, 6, 8, 15 for loading 1 and transferring trays from rus to rus and chimney 20 with windows and windows at the top and bottom with dampers to direct the smoke up or down the chamber in order to process the product under different conditions x (fig. 1-3).
