Description

N0

; l The invention relates to equipment for the food industry, and to devices for producing smoke from wood sawdust. The Smoke Generator is known, consisting of a shaft chamber in which burning of sawdust takes place from top to bottom, ashpit and jude water located in the lower third of the chamber. The disadvantage of this smoke generator is its cyclic operation, because to continue the work of the smoke generator, it is necessary to remove ash M filling camera a new portion of OSHLOK. In addition, the smoke generator does not provide for the regulation of the temperature of smoke formation, which may entail an increase in the content of harmful substances in the cinema, for example. 3 benzpnrena. When this smoke generator is working, it becomes dy unstable in its X1 4 and physicogochemical parameters, since moisture, released during the burning of sawdust, absorbs from the bottom of the sawdust, and the more the sawdust in the chamber burns, the stronger it will dampen sawdust in the chamber. bottom of the camera. An increase in the moisture content of sawdust negatively affects the concentration of such important components as phenols. During operation, the generator smoke during the combustion process of sawdust changes the humidity of the smoke house d'v 1a. During the burning of sawdust 8 in the upper part of the chamber, the smoke has a low humidity: and when burning in the lower part of the chamber of wet sawdust, the smoke has an increased humidity, which negatively affects the smoking process of the product 14, which is closest to the invention to the technical essence, is dyyrgeneterr, containing a vertically installed combustion chamber with 6 slit openings for smoke exhaust, a hopper for sawdust with agitator disposed in it, a vertical auger, an ash collector with a device for discharging the latter and a smoke box C However, Apparatus ohm feed sawdust is carried downward and the combustion of sawdust will OJEC Pechen uniform front .pok describe combustion and a constant composition of the smoke. The purpose of the invention is to provide an even burning front for sawdust and to obtain smoke smoke of a constant chemical and physico-chemical composition by feeding sawdust upwards to the burning front. The goal is achieved by the fact that in a smoke generator containing a vertically installed combustion chamber with slotted holes for smoke exhaust, an opi.kunker with an agitator located in it, a vertical auger, a collection of ashes with a device for discharging the latter and a dzhessbornik according to the invention of the lower part the combustion chamber is located in the hopper for sawdust, the vertical auger is passed through the bunker and the combustion chamber, and the ash removal device is installed directly above the upper edge of the combustion chamber. The agitator should be made in the form of a screw; all izheks should be fixed on a common shaft and their coils should be made in the opposite direction. The device for removing ash should be made in the form of blades fixed on the shaft, bent in the direction of their rotation, and is individually driven. FIG. 1 shows a smoke generator, side view; in fig. 2 - a device for removal of ash, top view. The smoke generator consists of a combustion chamber 1, a hopper 2 for sawdust, a collection of 3 ashes and a smoke box k. The combustion chamber 1 is made in the form of a cylinder and is installed vertically. From the outside, there is thermal insulation around the entire perimeter of the combustion chamber 1. In the middle part of the combustion chamber, below the burning front of sawdust, holes 6 are made in the chamber walls in the form of vertical slots around the perimeter the width of which is less than the average diameter of sawdust. The ash collector 3 is located in the upper part of the smoke generator and has openings 7 for supplying water and an opening 8 for draining the ash-water mixture. In the upper parts of collector 3 there are nozzles 9 for supplying air to the combustion zone and damper 1Q to regulate the air supply, as well as window 11 for fueling sawdust. Above the upper edge of the combustion chamber 1 is installed a device for removing ash with a drive 12. Smoke collector k is located below the collector 3 at the level of the openings 6. It has a nozzle 13 for the removal of smoke. The sawdust bin 2 is located under the smoke collector k and has a turner 14 for sawdust; Combustion 1. The agitator ni auger tS have the opposite direction of the coils: the auger is left and voro, and the itel is right, and the common drive 1b is used. The collection 3, the smoke collector j and the hopper 2 for sawdust are separated from one another under 17 and 18. 8 D1 wall. The collector 1 and the pallet 18 are the loading windows 15 and 20 with sealing. A device for removal of ash from the top of the combustion chamber C) ig. 2) consists of a curved blade 21 mounted on the shaft 22.

The smoke generator works as follows.

Sawdust is loaded into the bunker 2 through windows 19 and 20. They turn on the water supply and discharge of the ash-water mixture through openings 7 and 8. At the same time, the TB drive is turned on. Voroittel 14, mixing sawdust, feeds them into the lower part of the bunker 2, where they are captured by the screw 15 and are fed upwards through the combustion chamber 1. When the sawdust reaches the upper edge of the combustion chamber 1, smoke is discharged through the nozzle of the smoke collector 13 and through the window 11

Sawdust ignite. The windows 19 and 20 are hermetically closed. With the actuator 16, a supply of sawdust is set at which the front of their combustion is at the level of the lower edge of the blades. The dampers 10 regulate the required air supply. The shaft 22 is then included with blades 21, which remove the top layer of ash formed. Smoke smoke forms in the smoke generator and is fed into the smoke chamber. The shutdown of the hedgehog unit is made by increasing the feed of sawdust by the screw 15. At the same time, the blades 21 cut the entire layer. tleyui (their sawdust. Then sequentially turn off the drive 16, drive 12, supply air and water and smoke. The use of the proposed smoke generator provides a continuous production of smoke without additional heat supply without smoking smoke with the necessary physicochemical and chemical parameters.

The dc generator is simple to manufacture and maintain.

The need of fish industry enterprises in these smoke generators is about 700 pounds.

The expected annual economic effect from the maximum use of the invention will amount to 800 thousand rubles for the fishing industry.
