Candle filters

Filter System

Candle filters are advanced pressure filtration systems widely used in sugar industries including beet sugar factories, sugar refineries, and sugar cane processing plants. These systems are designed to handle suspensions with low to moderate solid content, ensuring efficient clarification and filtration of sugar liquors and syrups.

With a robust design and automated operation, candle filters enhance process efficiency, improve filtrate quality, and reduce operational downtime, making them an essential component in modern sugar processing plants.

System Overview

The candle filter consists of a cylindrical vessel equipped with vertical filter elements (candles). These elements are designed to retain suspended solids while allowing clean liquid to pass through. The system operates under pressure, ensuring efficient separation and high throughput.

The filtration process is fully automated using advanced control systems, ensuring consistent performance and minimal operator intervention.

Applications

• Filtration of carbonated juice (1st & 2nd carbonation)
• Safety filtration of thin juice
• Syrup and sugar liquor filtration
• Thick juice filtration in evaporation process
• Use in beet sugar, cane sugar, and refinery operations

Working Principle

The filtration process begins with feeding the slurry into the filter vessel. The liquid passes through the filter media while solids accumulate on the candle surfaces, forming a filter cake. This cake enhances filtration efficiency and improves clarity.

Once the filtration cycle is complete, the system automatically initiates cleaning or regeneration processes, ensuring continuous and efficient operation.

Key Features

• Fully automated PLC-based control system
• High filtration efficiency with superior clarity
• Adjustable thickening rate based on process requirements
• Low maintenance and durable construction
• Energy-efficient cleaning system (CIP optional)
• Quick replacement of filter elements
