Evaporation - smbsc.com From this tank the thin juice is pumped through a series of multiple effect evaporators. These evaporators are designed so that the vapor given off by the boiling juice in the first or previous evaporator is the heat source for the next evaporator.
Intelligent controller for multiple-effect evaporator in the ... Abstract: This paper proposes a control scheme to control a multiple-effect evaporator (MEE) in the sugar industry using fuzzy logic control (FLC). An algorithm using genetic algorithms (GAs) is proposed and used to automatically tune the scaling factors (SFs) and membership functions (MFs) of the FLCs.
COMPARISION OF SINGLE AND MULTIPLE EFFECT EVAPORATOR - Blogger The single effect evaporator uses rather more than 1 kg of steam to evaporate 1 kg of water. The latent heat of the vapor leaving in single effect evaporator is not used but is discarded. Much of this latent heat, however, can be recovered and reused by employing a multiple - effect evaporator, that is, vapor from one effect serves as heating ...
multiple effect evaporator - S.K.Associates We designed evaporator with our latest technology and practical knowledge in various field of industries, and we offer clients suited specially designed multiple effect evaporator that specifically suitable for production applications or waste water management applications.

Multiple-effect evaporator | chemical process | Britannica.com In sugar: Concentration. In the multiple-effect system, developed for the American sugar industry in 1843, steam is used to heat the first of a series of evaporators. The juice is boiled and drawn to the next evaporator, which is heated by vapour from the first evaporator. The process continues through… Read More
The development of controllers for a multiple-effect ... One of the most important task in sugar production process is to ensure an optimum working regime for the multiple-effect evaporator. In this paper we pres The development of controllers for a multiple-effect evaporator in sugar industry - IEEE Conference Publication
RMP Lecture Notes - Christian Brothers University Multiple Effect Evaporators. Evaporators are classified by the number of effects. In a single-effect evaporator, steam provides energy for vaporization and the vapor product is condensed and removed from the system. In a double-effect evaporator, the vapor product off the first effect is used to provide energy for a second vaporization unit.
Sugarcane mill - Wikipedia A batch type sugar centrifuge separates the sugar crystals from the mother liquor. These centrifuges have a capacity of up to 2,200 kilograms (4,900 lb) per cycle. The sugar from the centrifuges is dried and cooled and then stored in a silo or directly packed into bags for shipment.
How Cane Sugar is Made - Evaporation How Cane Sugar is Made - Evaporation The mixed juice from extraction is preheated prior to liming so that the clarification is optimal. The milk of lime, calcium hydroxide or Ca(OH) 2, is metered into the juice to hold the required ratio and the limed juice enters a gravitational settling tank: a clarifier.
200 YEARS OF PROGRESS IN THE LOUISIANA SUGAR INDUSTRY - ASSCT allowed the industry to quickly expand outside of the New Orleans area. Norbert Rillieux, a free man of color born in New Orleans and educated in Paris, installed his invention, the first triple-effect evaporator, in 1834. However, it was not until 1843-1844 that his multiple-effect evaporation process was proven successful.

Evaporator - Wikipedia The number of effects in a multiple-effect evaporator is usually restricted to seven because after that, the equipment cost approaches the cost savings of the energy-requirement drop. There are two types of feeding that can be used when dealing with multiple-effect evaporators.
History of Sugar - From Early Sugarcane Cultivation As early as 1820, sugar became treated in multiple-effect evaporator that was designed by American engineer Norbert Rillieux. Final but very important improvement in the process of sugar production came in 1852 when American David Weston introduced mechanical way of separating sugar from molasses in Hawaii.
