SU58345A1 - Device for continuous cooking of starch-containing raw materials in the alcohol industry - Google Patents

Description

Devices are known for the continuous cooking of raw materials in the alcohol industry, consisting of interconnected preheaters, in which the preheating of the processed raw material, the boiller and the preheater for the final cooking of the raw material are preheated.

The proposed device is different from those known to be used in a razvarivatel plates with drain cups and a special device of the vessel vessel.

In FIG. 1 schematically depicts the proposed device in section, FIG. 2 is a version of a broomstick.

Grain or potatoes from the hopper 14 is fed into the preheater-agitator 3 using a dispenser 15. When processing grain into the mixer, water from the collector 16 is simultaneously supplied to the dispenser 77. The dispensers 15 and / 7 are interconnected by a flexible connection so that a certain amount of water (per 1 kg of grain 1.7-2.0 / cg of water). The water in the collection 16 is heated by the return

steam coming through pipe 7 and steam released when blowing, supplied by pipe from the separator 18.

Potatoes or grains with water are heated in a preheater of 3 to 100 ° C with stirring, then kept at this temperature for some time, for which the preheater must be of proper length.

The contents of the agitator are heated at the beginning by returning steam supplied through pipe 19, and then with steam from a boiling pan through pipe 20.

In the mixer 8, several vertical partitions can be installed, as indicated in the drawing, in order to increase the path traveled by the raw material.

Heated to 100 °, the mass is turned by means of a turnstile 9 into a high-pressure pot, consisting of two vertical cylinders / and 2, connected to each other by a pipe 4, on which an apparatus 25 is installed for adjusting the mass level in said cylinders. Through the pipe 5, the ready mass is removed from the vessel 2 to the separator 18.

The cylindrical welder 1 is equipped with ring collars 10, the bent edges of which are immersed in plates II equipped with drain pipes 12. To form a hydraulic shutter, the ends of the drain pipes 12 are immersed in cups 13. Flowing into the plates // the mass flows through the drain cups 12 from plate to plate down and sparging on the plates, rising below the steam, passing through the holes between the collar JO and the edges of the plate 11.

In the lower part of the razvarivatel 1 to the level of rti-J2, there must be a mass stirred by the steam entering through the bubbler 22 and the pipe 24. The falling mass here is already heated to a temperature corresponding to the pressure in the apparatus (3-5 atm.), Since it passed successively all top plates. Therefore, the steam entering through the sparger 22 will not condense, but will go upwards, mixing the mass, then, after all the plates have passed, the pipe 20 will be drained into the preheater mixer 3.

The pressure here is automatically maintained by means of a reducing valve 23 at one constant predetermined value. The heated mass from the razvarivatel / tube 4 is retracted into the vessel 2 at a constant level "1-" 1, supported by a level regulator 25. The column 2 is provided with horizontal incomplete partitions 26 with downward bent ends, so that each of these partitions forms a vapor pillow A small amount of steam is introduced into the column through pipe 8 to maintain the temperature and gently mix the mass. The mass is expelled through a pipe 5 on which a valve is located, controlled by a level regulator 25.

If the blow valve on the pipe 5 is not open enough, the level will start to rise, and the pressure in column 2 will increase, the mass transfer through pipe 4 will decrease and the level Wj - 1 in column 1 will also increase. Then level control 25

the valve on the pipe 5 opens more, as a result of which the mass output increases, and it descends to the normal level.

The welded mass of the pipe 6 is directed to the separator 18, where the vapor formed during blowing separates, which, as indicated above, goes to the heated water.

In the processing of thick scrapers, the column / is supplied with an agitator 27 for stirring the mass on the plates (7) and in the plates 75.

The level regulator 25 is provided with a control float located in a vessel mounted on pipe 4 and communicating with the latter, as a result of which the mass in this vessel is at a level. In order to ensure tightness, the regulator is equipped with a casing covering all the connections and control parts of the valve.

The subject matter of the invention.
