Sigma develops fluid handling and nutrient injection system for the dynamic indoor farming industry
Sigma Design collaborated with a multinational food and beverage giant to develop a nutrient dosing system for their newly developed indoor hydroponic agriculture farm. We used our extensive background with fluid handling systems across many industries to perfect a water and nutrient dosing system in a well packaged and well engineered skid to fit their final dimensional layout required at their facilities. Pumps were selected after Sigma Design did a review of components suggested by our customer, and our background helped us optimize some components to better fit expected operating conditions.
Services Performed: Fluid handling skid design, component selection and optimization, metal fabrication, hydrostatic pressure testing, design optimization

Serving Safe Chicken: Meeting FDA Requirements for Safe Food Holding Temperatures
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 performing a heat power analysis and thermal FEA on the heater element and control circuit.
The tray is designed to keep rotisserie chickens at a safe internal temperature of 140°F and breakfast sandwiches at a slightly lower temperature, determined by a high and low setting that is set by an operator’s switch.
Step one 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.
Step two 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.
