A Showcase of New Jersey Innovation

Sigma Design was among the many New Jersey companies to exhibit at the New Jersey Technology Conference’s (NJTC) Venture Conference held in New Brunswick on March 22. The conference gives companies a stage to showcase their products or services to members of the investment community.

Sigma’s exhibit booth showcased a Tissue Embedder and Cryo prototype that was made in-house by Sigma. The Cryo System is a laboratory apparatus for more effective tissue sample preparation.

We enjoyed meeting many attendees and sharing our passions about new product design and manufacturing.  Sigma is a proud member of NJTC and supports its mission.

Sigma Not Chicken To Take On Complex FEA Project

How much heat does it take to keep food safe for consumption? Sigma used its advanced engineering skills to answer this question. A New Jersey-based company asked Sigma to analyze their warming tray prototype by preforming a heat power analysis and thermal FEA on the heater element and control circuit.

This model was created to show the surface temperature of the warming plate.

This model was created to show the surface temperature of the warming plate.

The tray is designed to keep rotisserie chickens at a safe internal temperature of 140°F and breakfast sandwiches at a slightly lower temperature. This will be determined by a high and low setting that is set by an operator’s switch.

The first step was to determine the steady state heat power requirements to keep the chicken at temperature by using hand calculations. Then a simplified FEA was run to verify that it matched the
hand calculations.

The next step was to source heater elements that match the power requirements found in the hand and FEA calculations from the previous steps. The final step was to determine a control circuit to keep the surface temperature of the plate as constant as possible, meeting the FDA requirements for safe holding temperatures.
