Calculation of Water Removal and Flow of Recycle in Sugar Juice Production

In sugar juice production, the process involves feeding sugar juice at a certain concentration into an evaporator, mixing it with filtrate, evaporating water content, and cooling the concentrated sugar juice to produce solid sugar. To calculate the amount of water removed in the evaporator and the flow of recycle, we need to follow a series of calculations.

The first step is to calculate the mass balance and concentration of the sugar juice at each stage of the process:

1. Mass of Sugar in Feed Sugar Juice

10,000 lb/h * 0.40 = 4,000 lb/h

2. Mass of Sugar in Filtrate from Crystallizer

4,000 lb/h * 0.05 = 200 lb/h

3. Mass of Sugar in Product of Evaporator

4,000 lb/h - 200 lb/h = 3,800 lb/h

4. Mass of Solution in Evaporator

3,800 lb/h / 0.50 = 7,600 lb/h

5. Amount of Water Removed in Evaporator

7,600 lb/h - 3,800 lb/h = 3,800 lb/h

6. Flow of Recycled Filtrate

200 lb/h * 0.45 = 90 lb/h

Therefore, the amount of water removed in the evaporator is calculated to be 3,800 lb/h, and the flow of recycle is determined to be 90 lb/h in the sugar juice production process.

By understanding and applying these calculations, the efficiency and effectiveness of the sugar juice production process can be optimized for maximum output and quality.
