SU19181A1 - Dextrin preparation device - Google Patents

Description

. The proposed device is intended for the preparation of dextrin with a stitch of acid treatment of the starch in an eccentrically mounted boiler on an axis, with a coil inside, a removable top bottom and fittings for input into the steam coil and inlet of irrigating liquid to the boiler.

In FIG. 1 shows a longitudinal vertical section of the device; FIG. 2, 2, 2-longitudinal and transverse sections of the inlet-steam device; FIG. 3 is a longitudinal vertical section of a device for injecting liquid into a vtel; FIG. 4-cross-section of the boiler; Fig. 5 and 6 are views of the end part C of the bottom in two modifications.

The proposed device consists of a cylindrical boiler 14 (Fig. 1), fixedly fastened (by soldering or welding using tightening hoops 16) with the tubular axis 15 passing through the boiler, somewhat different from the diagonal and lying in bearings 10, 10, 10 on racks 13, 13, 13.) The bottom bottom 19 of the boiler 14 is tightly presented with its body, and the top 47 is removable for the purpose of material loading and unloading products

The boiler 14 is heated by steam passing through a coil 12 made up of pipes 12

(Fig. 1, and 4) fastened with transverse strips 11, 1G, 11, the ends of which are bolted 1 to the body of the boiler 14. When the boiler 14 rotates on the axis 15, the coil 12 serves to loosen and mix the material. Sometimes the boiler body is double-walled and the space 20 between its walls 17 and 17 is equipped with a coil with steam introduced into it through pipe 21 and filled with rapeseed oil for heat transfer- The steam enters the device through pipe 22 and with the help of taps 23 either through pipe 21 into the coil between the walls 17 and 17, or through the pipe 24 into the internal coil 12. To introduce steam into the device and remove condensation water from it, a special device is installed on the axis 15 (FIG. 2) consisting of a sleeve 30 with discharged into it two chambers 28 and 27, gasket 31 and glands 32 and 32, clamped at ontsov sleeve 30 covers 34 and rings 36 to couple with a wire and the branch tubes 25 and 26; chambers 28 and 27 in their middle part, where they are much thinner, have holes in the circumference; The tubes 25, 26, inserted into the axis and rotating with it, fit into these chambers and, thanks to the holes, have a connection with the fixed tubes 25 and 26. To lubricate the equipment, an oiler 35 is installed. Thus, steam comes from the fixed tube 25 into the chamber 27, from which through the pipe 25 going inside the axis 15, J the bearing 10 is mined, it is discharged from the body of the axis and through the ring 29 enters the coil 12 of the device. The exhaust steam and condensation water from the coils 12 flows through the ring 29 into the pipe 26 laid inside the axis 15, then into the chamber 28 and through the pipe 26 a collector is discharged. A similar device was used to inject fluid into pipe 40: from the stationary sleeve 38, which closes the end of the hollow axis 15, through pipe 39, the liquid enters a rotating perforated pipe 40 located inside the device. Exhaust steam through the pipe 26 through the ring 28 out of the boiler. A thermometer is installed above the ring 28 to measure the temperature in the device and a gland 41 is sealed on the sides of this ring, which is clamped to the sleeves with flanges 34 and installed bolts. The removable bottom 47 in one half has a hatch 6, which is closed hermetically hinged on hinges with a lid, and in the other half of the bottom there is a device for releasing air and gases developed during the processing of starch, consisting of two movable plates 5, provided with slots 2; Inside the boiler, under the bottom, a rotating rotary is attached to the special one. lever cover with the same cuts installed to adjust the th gi. In another embodiment, the removable bottom has a square hermetically sealed throat 4 for loading and unloading material and a filter 3 consisting of a double frame, a tightly closed gate valve and a material that can be filled in with some porous material for passing steam and moist air. - Subject of the patent. 1. A device for the preparation of dextrin by starch treatment with acids, which is characterized by the combined use of: a) a rotating inclined boiler 14, whose side walls are fastened around the bottoms of the sleeves 16 with a hollow mounted on racks 13, 13, 13, with an axis 15, fitted with an attached bottom bottom bottom 19 and removable upper 47, coil 12-of pipes 12 for heating and mixing the material being processed, connected by strips 11, 11, 11 and pipe 40 for acid intake, b) devices for introducing steam into the coil 12 and withdrawing condensation water, from 19 pipes 21 24 that are passed through the blind bottom, entering the black, without the ring 29 into the axle 15 and terminating in the ring chambers 28 and 27 of the MI part, put on the bearing, driving gear 42 the end of the axle 15 and fitted with a gasket 31 between the chambers 28 and 27, glands 32, 32 at the ends and fixedly held by rings 36 with steam driving and discharge pipes 25 and 26 and c) devices for fluid injection — into pipe 40, consisting of a part I, worn on the other end 15, with gland 41 closed at the end of the sleeve -. 38 with a fixed steam pipe 39 (Figs. 1, 2, 3, 4, and 5),, 2. The form of execution of the removable boiler cover specified in paragraph 1, characterized by using a hinged door 6 and using KHOro for air and developing during processing starch gases are fixtures made of two movable plates 5, fitted with slots 2 (Fig. 5) or from hatch 4 and frame with a retainer 3 (Fig. 6). 3. With the boiler specified in paragraph 1, use the casing 17 to form an oil , Noah shirts (Fig. 1).
