Description

The invention relates to the food industry and can be used in the production of sugar from beets, inulin from chicory and Jerusalem artichoke and other soluble substances from plant materials.

A continuous diffusion apparatus is known, including two vertical columns connected in the lower part by means of a pipe, one of which is equipped with a chip loading device and a diffusion juice removal device, and the other has a pulp discharge device and a solvent supply device countercurrent to the chip movement.

The movement of the juice mixture is carried out in a pulsating mode by connecting the upper part of the discharge column to a vacuum line or connecting to the atmosphere. The pulp unloading device is made in the form of a horizontal squeeze screw. To prevent the chips from moving in the columns in the opposite direction, hinged grids are installed in them (SU 131689, January 11, 1960).

The disadvantage of this apparatus is the complexity of the design as a result of the installation of articulated gratings. Such gratings create increased resistance to the movement of the chip mix, which reduces the speed of its movement in the columns and requires increased energy costs for creating a vacuum.

The technical result of the invention is to simplify the design of the apparatus and reduce energy consumption during operation. This result is achieved by the fact that in the proposed diffusion apparatus, including two vertical columns connected in the lower part by means of a pipe, one of which is equipped with a device for loading chips and a diffusion juice removal device, and the other with a pulp unloading device and a solvent supply device, countercurrent movement shavings, a screw with perforated turns is installed in the pipe connecting the columns.

In the lower part of the column, equipped with a pulp unloading device, a drainage disk is placed with the possibility of periodic vertical movement to move the chips to the specified device. This column is equipped with a perforated valve, periodically introduced into it when the drainage disk is in its upper position to prevent the chip from moving in the opposite direction.

The invention is illustrated in the drawing, which schematically shows a diffusion apparatus in longitudinal section.

The apparatus consists of two vertical columns. Column 1 is equipped with a device 2 for loading chips and a device 3 for draining the diffusion juice 3. Column 4 is equipped with a device 5 for unloading the pulp and a device 6 for feeding the solvent. The columns in the lower part are connected by a horizontal pipe 7. A screw 8 with perforated turns is installed in this pipe. The lower part of the column 4 is equipped with a drainage disk 9, driven vertically by means of a hydraulic cylinder 10. Above the drainage disk 9 is a perforated valve 11, which can be inserted into and removed from the column by means of a hydraulic cylinder 12.

The device operates as follows. The raw material shavings to be extracted are loaded into the chip loading device 2 located in the upper part of the vertical column 1. The shavings move downward towards the screw 8 under the action of gravity. In this case, the drainage disk 9 is in its lowest position and the perforated valve 11 is located in column 4. With the screw 8, the chips are fed into the space filled with extractant between the drainage disk 9 and the perforated damper 11. After filling this space with the chips, the screw 8 stops. Under the action of the hydraulic cylinder 12, the perforated valve 11 is withdrawn from the column 4. The drainage disk 9 under the action of the hydraulic cylinder 10 rises, moving the chips above it up the column 4 to the device 5 for unloading the pulp. The solvent is supplied through the device 6 located at the top of the column 4. Diffusion juice passes through the chip layer in the column 4, the drainage disk 9, the perforated turns of the screw 8 and is removed from the apparatus through the device 3. After the drainage disk 9 reaches the upper position, the perforated column is introduced into the column 4 the valve 11, and the drainage disk 9 moves down. After the disk 9 reaches its lowest position, operations are periodically repeated. With the screw 9, the chips are fed into the free space between the drainage disk 9 and the perforated valve 11. Thus, the chip moves downward from the chip loading device in the column 1 and up to the pulp discharge device in the column 4, and the solvent from the solvent supply device 6 down into the column 4 through a horizontal pipe 7 and up to the device for draining the diffusion juice 3 in the column 1 provides a process of continuous extraction of the soluble component from the raw material shavings.

The proposed apparatus has a simpler design than the known one and allows to reduce energy consumption during operation.
