  • Coating drum for cooked pasta
    Patent number: 5755880
    Abstract: A double walled drum of concentric cylinders having end seals and insulation between the cylinders. The drum is open at both ends and rotates on its center longitudinal axis which is pitched from the horizontal with the entrance on the high side. Diameter restrictions at the entrance and discharge ends of the drum increase product residence time. Lifters at the entrance end discharge end push flexible strandular food subject to microbial spoilage such as strands of cooked pasta away from the entrance and out the discharge. Pins are mounted perpendicular to the inner cylinder wall and point to the central axis of the drum. Liquids such as acid and oil are sprayed onto the food in the drum from a spray bar or spray manifold. The pins continuously lift and separate the strands of food while it moves through the drum, and mix the liquid and product, resulting in a uniform coating. This process and apparatus produce a uniformly coated flexible strandular food such as spaghetti with minimal temperature loss.
