low temperature scraper evaporation
Low temperature scraper evaporation represents a cutting-edge thermal processing technology designed to concentrate heat-sensitive materials efficiently while preserving their essential properties. This advanced system operates by creating a thin film of product on a heat transfer surface, which is continuously scraped by rotating blades. The process occurs at significantly lower temperatures compared to traditional evaporation methods, typically ranging from 40°C to 70°C. The system's core component consists of a cylindrical vessel with a jacketed wall for heating, where product enters and is distributed evenly by the rotating scraper blades. These blades maintain constant surface renewal, preventing product buildup and ensuring optimal heat transfer efficiency. The technology incorporates precise temperature control mechanisms and vacuum systems to facilitate evaporation at reduced pressures, making it particularly suitable for processing temperature-sensitive materials such as pharmaceuticals, food products, and biological substances. The process achieves high concentration rates while minimizing thermal damage to the product, maintaining its original characteristics, nutritional value, and functional properties. The system's design allows for continuous operation, automated cleaning processes, and integration with existing production lines, making it a versatile solution for various industrial applications.
