A method of operating a blender having a rotatable cutting blade in a food preparation chamber includes providing a sensing light assembly, generating at least one sensing light beam below the food preparation chamber, inserting a cup containing food to be blended into the food preparation chamber, generating an error signal if a foreign object crosses the sensing light beam, and preventing or stopping rotation of the cutting blade in response to the error signal.

An ingredient blending system for food and beverage applications incorporates a manifold body with a blending chamber, ingredient inlet ports, egress ports, and ingress ports to facilitate ratiometric mixing of multiple ingredients. The system employs a pump connected to an egress port to create suction, eliminating the need for positive pressure pumps at the inlet. Valve caps maintain selected ports in a permanently open state, enabling fluid communication for continuous flow, while electronic valves provide selective control. The system supports dynamic ingredient flow control, with configurations allowing pressure sensors to monitor ingredient flow or be replaced by sensor caps for simplicity. The blending chamber achieves precise mixing ratios based on port dimensions and supports diverse ingredient types, such as liquids and gases. Designed for scalability, the system enables efficient cleaning and maintenance, making it suitable for high-demand environments like frozen beverage or soft-serve ice cream equipment.
