Chinese Professional Scraped Surface Heat Exchanger Calculations - Scraped Surface Heat Exchanger Model SPK China Manufacturer – Shipu

General Description

A horizontal scraped surface heat exchanger that can be used to heat or cool products with a viscosity of 1000 to 50000cP is especially suitable for medium viscosity products. Its horizontal design allows it to be installed in a cost-effective manner. It is also easy to repair because all components can be maintained on the ground.

•  Coupling connection
• Durable scraper material and process
• High precision machining process
• Rugged heat transfer tube material and inner hole process treatment
• The heat transfer tube cannot be disassembled and replaced separately
•  Adopt Rx series helical gear reducer
• Concentric installation, higher installation requirements
•  Follow 3A design standards

It shares many interchangeable parts like bearing, mechanical seal and scraper blades. The basic design consists of a pipe-in-pipe cylinder with inner pipe for product and outer pipe for cooling refrigerant. A rotating shaft with scraper blades provides the necessary scraping function of heat transfer, mixing and emulsification.
