Patent DE-19837958-C1 (DE)
Title: Process to extract sugar crystals from cane recovers heat from an intermediate heating process for re-use, maximizing energy efficiency
Inventor: FARWICK ERWIN
IPC: C13B10/04
Filed: 1998-08-21
Granted: 2000-03-02
Abstract: In a process to extract sugar circulating juice which has run through the last intermediate heating process, it is then subjected to two or more percolation stages in which it surrenders heat to a sugar bed inlet zone.  In a process to extract sugar from sugar cane, sugar cane is supplied at ambient temperature and is surrendered to a crusher. The crushed cane then passes through a diffuser (1) in which it is heated for sugar extraction. As the moving bed of crushed can leaves the diffuser, it is heated to about 75 deg C by imbibition water released over and percolates through the departing crushed cane, while it is repeatedly re-heated. The hot water is captured below the percolation layer and is returned to the top, the process being repeated several times until the sugar-enriched heated fluid reaches the diffuser inlet. The raw juice is then passed through a purification process prior to multi-stage evaporation and conversion to thickened juice and crystallisation. After the circulating juice has run through the last intermediate heating process, it is then subjected to two or more percolation stages in which it surrenders heat to the sugar bed inlet zone.

Abstract: Система контроля электропроводимости включает в себя по меньшей мере один измерительный модуль, подсоединенный между двумя проводниками системы энергопитания. Измерительный цикл делится на два периода. В течение первого периода модуль осуществляет измерение (F1, F2) первой постоянной составляющей напряжения (V1), представляющей паразитные составляющие постоянного тока, подаваемого на выводы модуля. В течение второго периода измерительный модуль вводит в систему энергопитания постоянную составляющую тока и осуществляет измерение (F3, F4) второй постоянной составляющей (V2) напряжения, подаваемого на выводы модуля. Разность (Vc) между второй и первой составляющими используется для определения нарушения электропроводимости, при этом сопротивление линии вверх по ходу линии от измерительного модуля пропорционально этой разности (Vc). Первая и вторая составляющие (V1, V2) получаются расчетом средних (при необходимости средневзвешенных значений выборок постоянных напряжений, измеряемых в течение измерительных периодов) T m 1, T m 2), имеющих длительность меньшую или равную длительности указанных первого и второго периодов.
