Description

The invention relates to the food industry, in particular, to devices for carrying out the extraction process from tea (finished products, green tea leaf production waste). A sectional extractor is known, equipped with reloading and loosening blades L, Lack of preliminary drainage phase separation in this extractor does not allow the process to be carried out with sufficient efficiency). The closest to the invention according to the technical essence and the achieved result is a sectional extractor containing a cylindrical body divided by vertical partitions into sections, a horizontal shaft with blades and reloading buckets, braking partitions mounted on an axis with the possibility of rotation and reloading bins pi . Having a higher degree of efficiency, the extractor does not allow achieving high quality of extraction due to excessive boiling of tea particles, as well as freezing of the raw material in the ladle at the time of its transfer from one section to another. I The purpose of the invention is to improve the quality of extraction. The goal is achieved by the fact that in a sectional extractor for tea containing a cylindrical body divided by vertical partitions into sections, a horizontal shaft with blades and reloading buckets, braking partitions mounted on an axis can be rotated, and overload bins, the bottom of each the sections are inclined at an angle of 8-10 ° along the course of the movement of the product, with the bucket walls forming between them, an angle of 95-100, and each brake of the baffle is fitted with a sleeve mounted on the axle and rigidly connected to it under glom 5-10 ° to the axis. . FIG. 1 shows the extractor, section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - overload bucket; in fig. 4 — brake of a baffle, in FIG. 5 is a view B in FIG. 4. The extractor consists of an oblique qi, gyindric corpus 1, divided76. 1 on a row of consecutive sections using vertical partitions 2; In partitions 2, overflow holes 3 for liquid are located, which are cleaned by knives 4. Axis 5 has a shaft 5 on which mixing arms 7 and reloading buckets are fixed by means of levers 6 8 with perforated walls 9. A perforated guide sector 1O is fastened to the vertical partition 2. 2. Together with the housing 1 and the partition 2, it forms a drainage channel. The upper end of the guiding sector 10 is docked with the side wall of the transfer hopper 11, which serves to sequentially transfer material from one section to another. At the end of the drainage-extraction channel in front of the hopper 11, a brake partition 12 is installed, rigidly attached to the sleeve 13, mounted on the axle 14. The axis 14 is installed in the partition 2 By means of a bracket 15 and a spring 16, adjustable by means of a nut 17. The bottom 18 of each section The housing 1 has a slope of 8-10 along the product, the walls 9 of the bucket 8 form an angle of 95100 ° between them, and the brake of the baffle 12, the brake of the baffle with the axis 14 angle 5-10 forms the extractor works as follows. Tea raw material enters the first section, comes into intensive contact with a solvent-liquid, for example, hot water entering the last section of the extractor countercurrently to flow through the overflow holes 3 in the partitions 2. Under the action of the blades 7 and due to the slope of the bottom 18, the raw material moves into the area of operation of the reloading buckets 8, is captured by them and is pressed in the drainage channel under the action of the brake of the partition 12. Then the bucket 8 overcomes the resistance of the brake peregodki T2 and together with the material moves to an unloading position. Material under the force of gravity falls down and through the hopper 11 enters the next section. Full unloading buckets contributes to the fact that its walls form a corner of 95-100 mekdu. Installing the brake of the baffle wall 12 at an angle to the axis 14

contributes to the fact that at the time of spinning the brake, the baffle of the partition takes a position parallel to the rear wall of the bucket 8 and provides

best spin conditions. The material passes successively all sections of the extractor, and the resulting extract is removed from the first section of the apparatus.
