Description

The utility model relates to continuous devices designed to extract diffusion juice from beet chips in sugar beet production.

Known inclined screw machines used in sugar factories of high productivity (6, 9, 12 thousand tons of beet processing per day) [Silin P.M. "Technology of sugar" M., Pishchepromizdat, 1967, p.625].

Various options are known for continuous column diffusion apparatuses, including, for example, a cylindrical body with counterblades attached to its height by height, installed inside the body and equipped with blades for movement, each of which has an upper working and lower surface and in the rear part in the direction rotated the rear flat section, in the form of a comb [A. No. 1830951 A1, C 13 D 1/10, publ. 1996; A.S. No. 1549997 A1, C 13 D 1/10, publ. 1990; A.S. No. 1751214 A1, C 13 D 1/10, publ. 1992; A.S. No. 1835861 A1, C 13 D 1/10, publ. 1996].

However, the use of paddle shafts and counterblades leads to significant grinding of beet chips. This worsens the operation process and disrupts the filtration of liquid in the apparatus. To remove this effect, thick beet chips are used, but this increases the extraction time and degrades the quality of the diffusion juice. The use of conveying gratings for chips leads to caking chips on separate gratings, which also worsens the extraction process.

To avoid this drawback, two-column apparatuses are used. Known two-column apparatus, connected in the lower part by a knee, consisting of two half-knees, the left half-knee has a steam jacket, one of the columns has a loading drawer, a sieve belt, two heating chambers. In the second column there are drawers, a cylinder with a conveying device, a drawer with a strainer mounted in it and a blade device. The apparatus contains delaying grids for dividing the column of chips into separate sections. The driving force for moving the contents of the apparatus is the pressure difference over the material in the first and second columns. [Silin P.M. "Technology of sugar beet and refined production", M., Pishchepromizdat, 1958, p.135].

Known devices for producing diffusion juice require a significant extraction time (at least 60-80 min), pressure, elevated temperature, while the quality of the juice and its output remain low

The objective of the proposed utility model is a new structurally simple device for obtaining diffusion juice from sugar beets, which allows to reduce the temperature and known extraction time while maintaining a high yield and quality of diffusion juice.

The technical result consists in reducing time and lowering the temperature of extraction while maintaining a high degree of extraction and the quality of diffusion juice.

The technical result is achieved by the proposed apparatus, which is a container for the extraction of beet chips, made in the form of two vertical columns having a common horizontal section. One of the columns is divided into two zones by a vertical partition extending to the general horizontal section of the device, and one zone of the column is closed by a cover on which an electromagnetic valve is installed, connected to the compressor for

pneumatic pulses, and a liquid level sensor. The solenoid valve and fluid level sensor are connected to the control unit. Another open area of the column is equipped with a loading hatch for supplying raw materials. In the lower part of the first column above the general horizontal section there is a pipe for selecting diffusion juice. The second column in the upper part contains a pipe for supplying industrial water and a pipe for unloading the pulp. The pipe for supplying water is made in the form of a distributing device for the flow of water - combs.

Fig. 1 shows a general sectional view of the apparatus.

The proposed apparatus contains two vertical columns 1 and 2, connected at the bottom by a horizontal section 3. Column 1 is divided into closed and open zones by a vertical partition 4, reaching the horizontal section 3, and contains a nozzle 5 for draining the diffusion juice located above the general horizontal section 3 of the apparatus . On the cover of the closed zone of the column 1 there is an electromagnetic valve 6 connected to a compressor for supplying pneumatic pulses, and a liquid level sensor 7, which is a metal rod with a diameter of 10-12 mm The electromagnetic valve 6 and the level sensor 7 are connected to the control unit 8. In the open area of the column 1 there is a hatch 9 for supplying raw materials. The column 2 in its upper part contains a pipe 10 for supplying water and is connected to the pipe 11 for unloading the extracted material.

The inventive device is an apparatus for extracting beets connected to a crusher (beet slicer), a dispenser, a scalder heater, a squeezing device, which can be used as any device functionally designed for these purposes.

The device operates as follows:

Pre-crushed and scalded at 80-82 ° C for 2-5 minutes, sugar beets are fed into the hatch 9 of the open zone of the column 1. Under the influence of gravity, it falls into the lower horizontal part 3

apparatus, where under the influence of pneumatic pulses supplied through an electromagnetic valve 6 with a frequency of 30-360 pulses per hour, the sugar beet moves into the column 2. To meet it counterflow through the pipe 10 is supplied industrial water with a temperature of 10-25 ° C, which is an extractant and passing through a mass of chopped beets, it is saturated with sugar. When the liquid phase falls below the level of the sensor 7, the signal enters the control unit 8 and the pneumatic pulse is released into the atmosphere through the solenoid valve 6. The diffusion juice is taken through the nozzle 5, and the extracted beets in the form of a mass free of dropping liquid through the pipe 11 enters the squeezer device. The squeezed liquid through the pipe 10 can be returned to the extraction.

The apparatus operates on thin beet chips, which are not chopped in it, uniformly fills the entire apparatus along the length without mixing, the chips are uniformly desaccharized over the cross section of the apparatus. Preserving the structure of the chips provides good quality diffusion juice. The juice is light yellow, transparent, without impurity of the pulp. The specific load of beet chips of the apparatus is 750-800 kg / m ³ .

The results of experiments conducted on an experimental device manufactured according to the proposed application showed that with the following technical parameters:

apparatus volume - 23 l

the size of the vertical columns - height - 1.2 m, diameter - 0.10 m

horizontal length - 0.5 m

device productivity 30 kg beets / hour (sugar content in beets 16%)

extraction time - 30 minutes

the average process temperature is 30-40 ° C.

Benignity (D _b ) of juice, determined by the ratio

Where

C _x = sucrose content

CB = solids content

accounted for 90-95%.

The sugar content in the pulp (on the dry residue) is less than 0.3%.

Thus, the proposed apparatus allows to reduce the extraction time to 30 minutes and lower the process temperature to 30-40 ° C while maintaining the high quality of the juice and a high degree of sugar extraction, which achieves the claimed technical result.
