Abstract:
Scraped Surface Heat Exchangers (SSHE) are widely used industrially for the processing of food products with high viscosity, However, their complex geometry and the presence of seals for the rotating shaft, the food product entry and exit as well as the blade shaft connections make cleaning difficult. The fluid is subjected to a high friction force inside the SSHE itself due to the mixing provided by the scraping blades, inducing fluid stagnation, due to the weakness of flow dynamics in closed areas. The experiments were conducted to determine the hold-up volume for TSSSHE at fixed parameters i.e. steam pressure, flow rate and scrapper speed for water as a process fluid. It was found as 5 to 10 litres for operating parameter range (scrapper speed 200, 175, 40 rpm; flow rates 350 to 528 kg/h and steam pressures 3.5, 2.5 and 1 kgf/cm2 for first, second and third stage respectively).
