Fives Cail-KCP Limited


	Continuous Vacuum Pans

Fives Cail-KCP Limited's Continuous Vacuum Pans are the most preferred design throughout the world. 180 of these pans are working worldwide out of which as many as 40 are successfully working in India. The wide range of pans available allows FCB-KCP to supply a perfect match for the customers requirements.

Fives Cail-KCP Limited's Continuous Vacuum Pans are designed for

		Improved natural circulation
		Larger cross-sectional area of lateral passages to improve the circulation rates
		Significant reduction of hydrostatic heads achieved by specially designed sloping geometry of top of calandria

The superior features of Fives Cail-KCP Limited Continuous Vacuum Pans give many advantages including

		Usage of low pressure steam / vapour as heating medium
		Improved exhaustion
		Improved granulometry
		Flexibility of same pan design for A,B & C massecuites

Salient Features:

Geometry
Improved geometry of the shell and calandria reduces hydrostatic head to the extent of 400 - 900 mm which corresponds to a gain of 2 - 4^oC in temperature. Horizontal calandria provides the best compromise between load loss and heat transfer coefficient besides resistant to fouling, which means longer duration of operations.

Control Principle
Process control is based either on conductivity or predictive mass balance. In conductivity control, regulation of liquor flow is by measuring the conductivity in various compartments.
Predictive mass balance is based on material balance computed out of condensate flow and liquor flow to each compartments. This is used in highly automated sugar plants.

Non-Condensable Gas Extraction
Calandria steam circulation allows sufficient steam speed to have a methodical sweeping of condensate and non-condensable gases resulting better heat transfer. Non-condensable gases are extracted at the end of last passage with a small quantity of steam and is used for agitation through a vapour liquor injector.


	Major Advantages:

		Low steam consumption
		Uniform steam demand
		Use of low pressure steam
		Improved grain size quality
		Heat balance Optimization
		Reduced sugar losses

		Uniform product quality resulting in easy curing
		Improved Overall performance
		Easy operation
		Less space requirement
		Less manpower requirement
		Compatible to total plant automation
