Development and Performance Evaluation of Crusher Cum Scraper for the Preparation of Jaggery Granules
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
A crusher cum scraper for making jaggery granules was developed and its performance on recovery of jaggery granules of was evaluated. U trough vessel with centrally mounted helical scraping ribbons, distributing ribbons, primary crushing bars, crushing peddles and side scrapers constitute the working mechanism of machine. The effect of three machine parameters viz., operational speed, time of operation and feed rate on recovery of jaggery granules below a size of 3 mm was studied. Crystallized jaggery chunks were prepared from sugarcane juice by heating it at elevated striking temperature (124-126°C) and increasing pH of juice up to 6.4. The prepared jaggery chunks were crushed, stirred and scraped in developed machine to convert mass it into jaggery granules. Results revealed that the machine parameters significantly affected the recovery. Maximum recovery of 76.52% was recorded at an operational speed of 20rpm, time of 8min and feed rate of 2kg/min. The lowest granule recovery was observed at higher levels of all the three parameters because of combined effect of over crushing of jaggery chunks and it’s skipping from primary crushing bars.
