Q1. Describe the continuous methods of Khoa making with merits and demerits of each.
- Continuous Khoa making methods automate production for efficiency, hygiene, and consistent quality.
- Scraped Surface Heat Exchanger (SSHE) uses rotating blades to scrape milk from heated surfaces for rapid evaporation.
- SSHE merits include high capacity, improved hygiene, reduced labor, and uniform product quality.
- SSHE demerits involve high capital cost, complex maintenance, blade wear, and potential texture differences.
Answer: Continuous methods for Khoa making represent significant advancements over the traditional batch process, offering improved efficiency, hygiene, and product consistency. These methods leverage sophisticated machinery to achieve rapid heat transfer and moisture removal, transforming liquid milk into the semi-solid Khoa product. Traditionally, Khoa production involves manual stirring of milk in an open pan, which is labor-intensive, time-consuming, and prone to variability. Continuous processes a...
