K-Tron Process Group, Demaco, Northern Crops Institute, and DeMari Pasta Dies to Present Technical Seminar, "Pasta Quality & Extrusion Technology"

PITMAN, NJ - (January 11, 2011) - K-Tron Process Group, in collaboration with key suppliers of equipment and instrumentation to the food processing industry, including Demaco, Northern Crops Institute, and DeMari Pasta Dies announce the presentation of a joint food pasta processing seminar, “Pasta Quality & Extrusion Technology”, to be held at the Hyatt Place San Antonio / Riverwalk, San Antonio, Texas, February 9-11, 2011.

This three-day course provides a comprehensive presentation of basic and advanced pasta extrusion and processing. It will offer a detailed overview of all critical aspects of pasta extruder operations in theory and in practice. The seminar will provide detailed information on how to make quality pasta and a sound theoretical understanding of the dynamics of what is happening in a pasta extruder.

February 9-11, 2011
Hyatt Place San Antonio / Riverwalk

San Antonio, TX 78205, USA
Tel: (210) 227-6854
Topics to be presented include:

 Manufacturing Quality Pasta - focusing on the primary and secondary infeed systems, mixing, extruder designs, and pasta machine maintenance. Presentation title, “How to Choose the Proper Feeder Technology for your Pasta Production Process” focuses on feeder selection, technologies, volumetric vs. gravimetric feeding and their effect on mixer / extruder performance and refill options available.

 Basics of Pasta Extrusion: Dr. Levine will introduce elementary concepts in the rheology of materials. This knowledge will be used to develop the principles that describe flow in pasta dies and extrusion systems. The principles will be used to illustrate key points on die and systems design: The required precision in die machining and the design considerations when extruding complicated pieces.  The principles describing capacity and energy input for a pasta extruder will be discussed and these principles will be used to discuss the implications of screw design, stability of output flow, and scale up. Dr Levine will also review the design and flow of dough within sheet forming / rolling systems

 Raw Materials & Pasta Dies: Raw materials for pasta from the field to the extruder will be discussed, along with a discussion about how to specify raw materials that meet product objectives and the requisite quality control methodologies required insuring product consistency. Alternative raw materials used for Gluten Free pasta and other blends will also be covered.

Presentation covers how die inserts are designed to deliver a specific product shape along with how to specify product shapes for best results. Detailed methodologies for equalizing extrusion rate across the face of the die are covered in detail
