The object of research is
IMPROVEMENT OF A SCRAPER HEAT EXCHANGER FOR PRE-HEATING PLANT-BASED RAW MATERIALS
The aim of research is to
To improve the scraper heat exchanger (SH) for pre-heating plant raw materials before concentrating
Paper title
IMPROVEMENT OF A SCRAPER HEAT EXCHANGER FOR PRE-HEATING PLANT-BASED RAW MATERIALS BEFORE CONCENTRATION
Keywords
heating, scraper heat exchanger, cutting blade, heat removal, flexible film resistive electric heater of the radiating type
Main scientific results imply the following
The improved scraper heat exchanger is characterized time decrease in the specific energy consumption, used to heat a product volume unit, compared to the heater with a steam shell. The confirmed efficiency of using the improved scraper heat exchange
Scope of application
The improved SH is recommended for the rapid warming of plant raw materials using gentle temperature modes to 65 °C, namely before the concentration
Limitations for practical use
Violation of any technological parameters will inevitably lead to a decrease in the quality of the products received, reduce the resource efficiency
