Ball type scraper evaporator

A ball type scraper evaporator is a specialized piece of equipment used in the evaporation process, particularly for viscous or heat-sensitive materials. Here’s an overview of its key features, working principle, applications, and benefits:

Key Features
Design:
The evaporator consists of a cylindrical shell with a rotating ball-type scraper that continuously removes the concentrated product from the evaporation surface.
Scraper Mechanism:
The ball scrapers ensure a uniform film of liquid on the heating surface, improving heat transfer and preventing fouling.
Temperature Control:
Equipped with precise temperature control systems to handle heat-sensitive products without degradation.
Vacuum Operation:
Often operated under vacuum conditions to lower evaporation temperatures, which is ideal for sensitive compounds.
Modular Design:
Can be designed in multiple stages for enhanced evaporation efficiency, allowing for higher concentration of solutions.
Working Principle
Feed Introduction:
The liquid to be evaporated is fed into the evaporator.
Heating:
The shell is heated, causing the solvent in the liquid to evaporate.
Scraping Action:
The ball-type scrapers rotate and scrape the concentrated liquid from the evaporation surface, ensuring a thin film that promotes efficient heat transfer.
Vapor Removal:
The evaporated vapor is removed continuously, allowing for the continuous operation of the system.
Concentrated Product:
The concentrated liquid is discharged from the bottom of the evaporator.
Applications
Food Industry: Concentration of fruit juices, sauces, and dairy products.
Pharmaceuticals: Concentration of active ingredients and extracts.
Chemical Industry: Processing of polymers, resins, and other viscous fluids.
Benefits
Efficient Heat Transfer: The scraping action enhances heat transfer and prevents fouling.
Gentle Processing: Suitable for heat-sensitive materials due to low operating temperatures.
Continuous Operation: Allows for uninterrupted processing, improving productivity.
Versatile: Capable of handling a wide range of viscosities and material types.
