Do rozszerzonej górnej czesci rury w miejscu C2 przenosnik pasowy C1 wsy¬ puje cienka krajanke w takiej ilosci, aby ladu¬ nek przekroczyl 500 kg/m3 pojemnosci dyfuzji."Dyfuzja ta stanowi uzupelnienie i ulepszenie dyfuzji przedstawionej w opisie patentowym nr 40135.Mieszanina wody amoniakalnej A± i baro- metrycznej Bt zostaje odmierzona w dozowni¬ kach A2 i B2, proporcjonalnie do ilosci wprowa¬ dzonej krajanki. Pompa L7 podaje wode do dy¬ fuzji przez zagrzewacz M3, który w razie po¬ trzeby podnosi temperature wody do 70°.

Wieksza czesc soku podgrzewa we wspólpradzie krajanke w kierunku Jdc sit Kv a mniejsza czesc podgrzanego soku, w ilosci nieco wiekszej niz odciag soku surowego, ply¬ nie w przeciwpradzie do krajanki, która za¬ grzewa, a sam sok ochlodzony do okolo 40° od¬ plywa z sit E przez odplyw soku F do lapacza miazgi H, a nastepnie do wstepnej defekacji I.Z lapacza miazgi H pewna czesc soku z miazga J jest doprowadzona do pompy obiegowej Lr Sita E i Kx odpowietrzaja krajanke i sok prze¬ wodem G, polaczonym z próznia.Aby uzyskac lepszy obieg soku w dyfuzji i równa prace, ustawione sa dodatkowe pompy cyrkulacyjne (obiegowe) L2 — L6, czerpiace sok z sit K2 — K6. Prócz tego pompa L6 pobiera wo¬ de z wyzymaczek P przez lapacz miazgi S i po-daje do dyfuzji przez zagrzewacz rurkowy M2, regulujacy temperature koncowej czesci dyfuzji ciaglej.W celu zmniejszenia zuzycia pary na dyfuzji do 5 kg na 100 kg buraków, woda amoniakalna A przeplywa przez plaszczowe podgrzewacze N± — NAt utrzymujac pozadana temperature w dyfuzji, a obnizajac temperature wody kon¬ densacyjnej Av wprowadzonej na dyfuzje. Pod¬ grzewacze plaszczowe Nx — 2V4 sa wbudowane w dolnej- scianie splaszczonej rury dyfuzyjnej, poprawiajac w ten sposób równomiernosc pra¬ cy i naturalna cyrkulacje we wnetrzu rury dy¬ fuzyjnej. W celu zapewnienia dobrej pracy wszystkich sit E, K± — K7, sa one wykonane jako sita petlicowe z brazu i wpuszczone o 15 mm do wnetrza rury.

PLPublished on July 20, 1959 (U3rf ii & a LIBRARY OF THE POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 41998 KI. 89 c, 4 Prof. Dr. Stanislaiu Zagrodzki Lódz, Poland Continuous diffusion The patent lasts from January 17, 1958 The patent depends on the patent No. 40135 Continuous diffusion is built in the form of a long, flattened tube D, inside which the steelon baffles W are moved through two moor chains U, with a shape similar to the cross-section of the flattened tube D, made of frames on which are tensioned nets Into the flared upper part of the tube at the location C2, the belt conveyor C1 injects a thin slit in such an amount that the load exceeds 500 kg / m3 of diffusion capacity. "This diffusion supplements and improves the diffusion described in Patent Specification No. 40,135. ammonia water A ± and barometric water Bt are metered in dosing units A2 and B2, proportional to the amount of cut pieces introduced. Pump L7 supplies water for diffusion p by the heater M3, which, if necessary, raises the temperature of the water to 70 °. The introduced water flows by gravity in counter-current to the shifting slices and slurries through the entire diffusion up to the sieves K ± and E. The juice received in K ± circulation pump L1 is given by a few hundred percent in relation to the amount of processed beet. through the Mr tube preheater, the juice heated to the temperature of 80-85 ° separates inside the diffusion in two directions. Most of the juice heats the cut in the direction of Jdc sieve Kv, and the smaller part of the heated juice, in an amount slightly greater than the extraction of raw juice, flows in counter-current to the cut, which heats up, and the juice itself is cooled to about 40 ° from flows from the sieves E through the juice outlet F to the pulp catcher H, and then to the initial defecation I from the pulp catcher H a certain part of the juice from the pulp J is fed to the circulation pump Lr The sieves E and Kx vent the slices and the juice through the line G connected to the vacuum . In order to obtain a better circulation of the juice in diffusion and even work, additional circulation pumps (circulation) L2 - L6 are set, taking the juice from the screens K2 - K6. In addition, the pump L6 takes water from the chimney P through the pulp catcher S and diffuses through the tubular heater M2, which regulates the temperature of the end diffusion part continuously. In order to reduce the steam consumption for diffusion to 5 kg per 100 kg of beet, ammonia water A flows through the N ± NAt mantle heaters to maintain the desired diffusion temperature and to lower the temperature of the condensation water Av introduced into the diffusion. Nx - 2V4 jacketed heaters are built into the bottom wall of the flat diffusion tube, thus improving the uniformity of operation and the natural circulation inside the diffusion tube. In order to ensure good operation of all E, K ± - K7 screens, they are made as bronze loop screens and recessed by 15 mm inside the pipe. Steelon W partitions, placed on U chains, have double-sided rubber scrapers to clean all the screens. The pulp leaving the diffusion is dehydrated on a K7 sieve, and then through the O embankment they get to the lingering cyst P. Due to dehydration, the hot pulp has 7-8% of dry substance, and their amount is 65-75% Due to the importance of the beet. As a result, the efficiency of the chimney is increased, and the pulp removed with the R screw has the desired dry matter content. The diffusion is driven by a gear, gear and T chain wheels. The Y chain wheels are used to tighten the chains, and the Z wheels facilitate the running of the lovage chains. The lube chains slide inside the profile guides and are equipped with rollers to reduce resistance. PL
