A press is provided comprising a supporting framework, a tubular screen mounted upon the framework and a drum having tapered i.e. conical ends journaled for rotation coaxially within the screen and spaced a short distance from the inside surface of the screen. One or more scraping blades is attached to the drum in position to scrape the inside surface of the screen as a motor turns the drum. A moist elastic food product is introduced into the space between the screen and the drum and subjected to pressure during operation causing the moisture to be pressed through the screen. The press can be used for increasing the solids content of hydrated vital wheat gluten from about 22 percent to about 30 percent.
