ANS:D - all 'a', 'b' & 'c'

The advantage of continuous drying over batch drying is that all 'a', 'b' & 'c' are correct: a) Drying cost per unit weight of dried product is less: Continuous drying processes often offer economies of scale and higher production rates compared to batch drying. This can result in lower overall drying costs per unit weight of dried product due to reduced labor costs, energy consumption, and equipment downtime. b) Product with more uniform moisture content is produced: Continuous drying systems typically provide more consistent and uniform drying conditions throughout the process compared to batch drying. This can lead to a more uniform moisture content in the final product, reducing variability and improving product quality. c) Equipment size required is smaller: Continuous drying systems are often designed to operate continuously with high throughput rates, allowing for smaller equipment sizes relative to batch drying systems handling the same production volume. Smaller equipment size can result in lower capital costs, reduced footprint, and increased flexibility in plant layout. Overall, continuous drying offers multiple advantages over batch drying, including lower drying costs, improved product quality, and more efficient use of equipment and space. a) Drying cost per unit weight of dried product is less: Continuous drying processes often have lower operating costs per unit of dried product due to higher production rates, reduced labor requirements, and better energy efficiency compared to batch drying. b) Product with more uniform moisture content is produced: Continuous drying systems provide consistent drying conditions throughout the process, resulting in a more uniform moisture content in the final product. This ensures higher product quality and reduces variability. c) Equipment size required is smaller: Continuous drying systems are designed for high throughput rates, allowing for smaller equipment sizes relative to batch drying systems handling the same production volume. This reduces capital costs, space requirements, and improves overall efficiency.
