Description

(54) EXTRACTOR OF CONTINUOUS ACTION

one

Invention is applied to apparatuses: for de-sugaring beet chips by the diffusion method.

A continuous extractor izvesgen, consisting of short circuits of two connected in the lower part columns of rectangular section, in which there are two infinite plastic chains with attached frames for transporting Cl chips.

The disadvantages of this extractor is a high degree of wear and tear of injuries of the sports system, difficulty in tensioning the chains, poor filtering of the liquid through the chip layer ,. which is unevenly distributed on the framework when the apparatus is loaded.

Closest to the present invention is a continuous extractor having a cylindrical rotor, in the upper part of which there is an annular corb divided by partitions into sections, each of which is equipped with a perforated opening with a bottom chip unloading of the expanded chips, a loading shaft and a device for discharge , pipes for extractant and removal of C 2 1 juice.

However, the known extractor has an increased loss of sugar in the pulp during its operation due to the increased compaction of the chips, which increases the effect of mutual overlap of the latter. All this makes it difficult to have a good contact between the extracting liquid and the sugar beet springs.

The purpose of the invention is to reduce the sugar losses in the pulp.

Delivered. Pel is achieved by having a shigendric rotor in an E1Ertractor, having a shigendric rotor, in the lower part of which there is a ring box divided by partitions into sections, each of which I are equipped with a newly fortified open bottom plate, for unloading the shavings, and the drop shafts and accessories. the pulp outlet, the nozzles for the supply of the extractant and the juice outlet, the housing and the rotor are located at an angle of 15-40 ° to the vertical, while the walls of the box are perforated. . FIG. 1 shows the extractor, a general view; in fig. 2nd, longitudinal section; not figs. 3 - the same, top view. The extractor has a cylindrical rotor 1, in the lower part of which there is an annular duct 2 divided by perforated partitions 3 into sections 4, each of which is provided with a perforated open bottom 5 for unloading the shavings, loading shaft 6 and building 7 for removing waste, branch pipes 8 for supplying and (9 withdrawing the juice. The body 10 and the rotor 1 of the extractor are located at an angle of 15-40 / to the vertical. At the same time, the portions 3 of the box 2 are perforated with 1 mi. The extractor works as follows. Freshly cut beetroot The shipment is fed to the loading shaft 6, and then it is evenly distributed over sections 4 of the rotor 1. With the help of the drive station 11, the rotor 1 is rotated around the machine's axis (the direction of rotation is indicated by the arrow). gutters are fed into the apparatus with concentrated diffusioc juice with a temperature of 8 ° -85 ° C (pumping out ZOO%), which after passing through the layer of chips and the perforated section 13 of the bottom 14 is withdrawn from the device through the nozzle 15. Through the nozzle 8 into the apparatus atm fed extractant (barometric water) heated to 63 C-EB which after malting chip 16 is withdrawn through manifold 9 .. As the rotation of the rotor 1, each section 4 vysolozhennoy chips, i.e. pulp, passes over site 17 unloading. Due to the profile bending of the bottom 14 of the housing 1O, 5, rollers 18 are successively opened and released from the pulp, which then 9 4 is passed through the device 7. Pass the profile and bend, the bottom 5 is closed-t, section 4 is loaded again with chips, the process of sugar extraction continues non-performing . The operating temperature in the apparatus is maintained by steam chambers 19 located around the body of the apparatus. The design of the proposed extractor makes it possible to reduce the external diffusion resistance by increasing the velocity of the fluid relative to the chip and rotating the rotor when it is tilted within the specified limits. The presence of duct partitions prevents simultaneously the compaction of the chip layer in the sections and creates conditions for a good counter-current movement of the extractant. This makes it possible to reduce the sugar losses in the pulp and thereby increase the sugar yield, ceteris paribus. Claims of Invention A non-linear extractor having a cylindrical rotor, in the lower part of which there is an annular duct divided by partitions into sections, each of which is snagged with a perforated opening bottom for unloading the advanced chips, a discharge shaft and a device for discharging the branch, pipes for supplying the extractor and juice extraction, characterized in that, in order to reduce sugar losses in the pulp, the body and the rotor are arranged at an angle of 15-40; to the vertical, with the walls of the box filled with perforated.
