Methodology for Capacity Calculation

Calculating the capacity of a cane sugar plant involves a systematic approach that considers the above factors. The fundamental formula for capacity calculation can be summarized as:

Capacity (TPD) = Cane Input per day × Extraction Efficiency × Processing Rate

Let's explore the steps involved in detailed capacity estimation:

Step 1: Determine Cane Availability

• Calculate the total cane available during the harvest season based on crop yield and acreage.
• Example: If the farm produces 80 tonnes of cane per hectare and there are 1,000 hectares, total cane yield = 80,000 tonnes.

Step 2: Estimation of Cane Input per Day

• Divide the total cane by the number of operational days in the season.
• Example: If the season lasts 150 days, daily cane input = 80,000 / 150 ≈ 533 tonnes/day.

Step 3: Assess Extraction Efficiency

• Typically ranges from 85% to 95%, depending on cane quality and equipment.
• For calculation purposes, assume an extraction efficiency of 90%.

Step 4: Calculate Juice Production

• Juice produced per day = Cane input × Extraction efficiency.
• Example: 533 tonnes × 0.9 ≈ 480 tonnes of juice per day.

Step 5: Determine Sugar Recovery Rate

• The percentage of sugar recovered from juice, typically 10-12% of juice weight.
• Assume a recovery rate of 11%.

Step 6: Calculate Daily Sugar Production

• Sugar produced per day = Juice volume × Sugar recovery rate.
• Example: 480 tonnes × 0.11 ≈ 53 tonnes of sugar per day.

Step 7: Adjust for Plant Efficiency and Operating Hours

• Consider plant operating hours per day (usually 20-24 hours).
• Ensure equipment capacity aligns with these operational parameters.

Practical Example of Capacity Calculation

Let's consider a practical scenario:

• Total cane available: 100,000 tonnes.
• Harvest season duration: 150 days.
• Extraction efficiency: 90%.
• Sugar recovery rate: 11%.
• Operating days: 150.
• Operating hours per day: 20 hours.

Step-by-step calculation:

1. Cane input per day: 100,000 / 150 = 666.67 tonnes.
2. Juice produced per day: 666.67 × 0.9 ≈ 600 tonnes.
3. Sugar produced per day: 600 × 0.11 = 66 tonnes.
4. Plant capacity (TPD): Based on daily sugar production ≈ 66 tonnes.

This indicates that the plant’s designed capacity should be at least 66 TPD to handle this input efficiently.
