High-pressure scraped-surface heat exchanger

High-Pressure Scraped-Surface Heat Exchanger... [Pg.2877]

The high-pressure pumps are normally supplied with a pressure relief valve and associated product piping to protect the scraped-surface heat exchanger equipment downstream and the pump itself, should a blockage of the production line occur. [Pg.2876]

A filter is normally installed in the suction line to the high-pressure pump to protect the pump and the hard chromium-plated scraped-surface heat exchanger cyhnder from any foreign matter in the margarine emulsion. [Pg.2876]

Depending on the designed maximum product pressure of the downstream scraped-surface heat exchanger and the various types of margarine produced, high-pressure positive-displacement pumps with maximum discharge pressures of 40 bars (about 600 psi), 70 bars (about 1030 psi), or 120 bars (about ISOOpsi) are normally installed in the process hne.
