Description

(54) LINE OF CONTINUOUS GRAIN PREPARATION FOR ALCOHOLIC CONSTRUCTION

one

FIELD OF THE INVENTION The invention relates to the alcohol industry, and, as a matter of fact, to the lines for the continuous preparation of grain. on for alcoholic fermentation.

The preparation lines for starch-containing raw materials for alcoholic fermentation are known, containing a fine-grinding roller mill, chans mixer for preparing a batch, a plunger pump, a heater, a heat exchanger, a boiling pan, and a contact head.

The closest to the technical essence of the present invention is the line of continuous preparation of grain for alcoholic fermentation, including bunkers, elevators, scales, feeder, separator for separating foreign matter, chopper, dilution device and saccharification and fermentation battery G23

The disadvantage of this line is its non-compactness and the complex system of cooking the raw material at a pressure of 3 or more atmospheres, which does not allow to improve the conditions of its operation.

The purpose of the invention is to improve the operating conditions of the line and its compactness.

This goal is achieved by the fact that the line is equipped with an extruder installed after the shredder in front of devices for liquefying and Hassing 5, the latter being equipped with a system of vertical and horizontal reflectors installed on the inner side surfaces and lids of these devices, and mechanisms placed inside them for mixing and dispersing .

In addition, the chopper is made in the form of a cylindrical chamber with a shaft located inside it and

15 perforated discs, some of which are connected to the shaft, while others are located between the first and are connected to the lateral inner surface of the cylindrical chamber,

20, the openings of the perforated discs and the gaps between them are successively reduced in the direction of material unloading.

At the same time, MexaHH3NH for mixing and dispersing devices, for liquefying and saccharification are made in the form of perforated discs, one of which is fixed on the shaft, while others are located between

30 first and connected to internal

side surfaces of devices for liquefaction and saccharification.

Fig. 1 schematically shows a line for the continuous preparation of grain for alcoholic fermentation, an overall view in Fig. 2 — an extruder; Fig. 3: a dilution device; figure 4

chopper. /

The line includes a receiving hopper 1, noria 2, scales 3, intermediate hopper 4, feeder 5, separator 6 for separating foreign matter, noria 7, chopper 8, consisting of a cylindrical chamber 9, on the lid of which is mounted a hopper 10 rotating perforated discs 11 connected to the shaft 12, and stationary perforated discs 13 connected to the lateral inner surface of the cylindrical chamber. The discs are configured to adjust the gap between them. The line also contains an extruder 14J consisting of a housing with a control unit 15, a loading hopper 16 and a screw mechanism 17, a liquefaction device 18 consisting of a cylindrical body 19, inside of which are mounted mixing and dispersing mechanisms made in the form of alternating rotating discs 20 connected to the shaft 21, and stationary perforated discs 22 connected to the inner side surface of the housing 19, vertical reflectors 23 mounted on the inner side of the side of the building Usa 19, horizontal reflectors 24 mounted on the lid of the device 18 for liquefying the supply pipe 25 and flow pipe 26, the pump 27, and the device 28 for saccharification, made similar to the device 18 for liquefaction.

Liney works like this

The grain is fed to the receiving bin 1, from where it is fed to the balance 3 with the help of noria 2, the weighed portion is poured into the intermediate bunker 4, which is matched with the feeder 5, from which through the separator 6 to separate foreign matter and noria 7 is sent to the chopper 8 which crushes the grains into particles of 1-3 mm in size in the gap between the perforated discs 11 and 13. The resulting grains are passed through an extruder 14, in which it undergoes thermomechanical processing at 100 ° C and then sent to the device 18 for liquefaction, where due to the rotation erforirovannyh discs 20 and 22 and the reflectors 23 and 24 is generated multidirectional turbulent flow, which is continuously circulated through a perforated

movable and fixed disks 20 and 22 and in the gap between which there is a systematic dispersion of the mixture.

After the mixture is liquefied by the pump 27, it is pumped over to the accumulation in the device 28, where the process takes place in the same way as described above, and then the mixture is sent to fermentation (no fermentation battery is shown).

The proposed line of continuous preparation of grain for alcoholic fermentation allows to improve the line operation and its compactness.
