Shortening units are constructed of carbon steel. The water phase in margarine is corrosive, and sanitation procedures require that all of the equipment used to manufacture it must be chemically cleaned. Margarine processing units contain chromium-plated commercially pure nickel heat transfer tubes and stainless steel for all product-contacted metal surfaces. 

Several shaft or cylinder designs are available today in A units for margarine processing. The A units can be grouped according to whether they are mounted with eccentric shafts, oval shafts, sectioned shafts, or oval tubes. 

The velocity at which this takes place will decrease as the viscosity increases. In a margarine process the most critical section is in the final scraped-surface heat exchanger (SSHE) and then toward the exit end. Here there is the greatest viscosity (highest Pr) and also the smallest temperature difference between the wall and the material (A0).
