Solution Overview
Problem
Current snack food manufacturing processes fail to produce high-quality, nutritious products without additives like plasticizers, dyes, chemicals, or artificial preservatives while also being energy-efficient and requiring minimal assets and space.
Innovation Solution
A method using an ultrasonic horn and anvil to agglomerate dry, low-moisture ingredients from the five food groups, applying gentle moisture and sonic energy to create a cohesive, three-dimensional product with visible ingredients, eliminating the need for large equipment and peripheral systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extrusion or oven baked processes are used to manufacture snack foods, then production efficiency and equipment footprint are improved, but nutritional integrity is degraded due to high temperatures and additives
Solution Approach 1:
The patent replaces thermal processing systems (extruders, ovens) with an ultrasonic horn that uses high-frequency mechanical vibrations to agglomerate particulate ingredients. This mechanical vibration approach achieves binding without the high temperatures that cause nutritional degradation, resolving the contradiction between production efficiency and nutritional integrity.
Solution Approach 2:
The invention changes the fundamental processing parameter from thermal energy (temperature) to mechanical energy (ultrasonic vibration frequency and amplitude). By operating at room temperature with controlled ultrasonic parameters, the process maintains nutritional integrity while achieving efficient production through rapid agglomeration.
2Ease of manufacture
If conventional oven baked processes are used to manufacture snack foods, then product formation is achieved, but energy consumption increases due to inefficient heat utilization
Solution Approach 1:
The patent replaces the energy-intensive thermal system with an ultrasonic horn that uses mechanical vibrations to bind ingredients. This substitution eliminates the need for large-scale heating systems and associated energy losses, achieving product formation with significantly reduced energy consumption.
Solution Approach 2:
The invention extracts and eliminates the thermal processing step from the manufacturing process. By removing the oven or extruder and using only ultrasonic vibration for binding, the process eliminates the majority of energy consumption associated with heating and maintaining temperature throughout the manufacturing system.
3Stability of the object's composition
If conventional extrusion processes are used to manufacture snack foods, then homogeneous mixing is achieved, but ingredient integrity is lost due to thermal degradation and over-processing
Solution Approach 1:
The patent uses ultrasonic vibrations from the horn to gently agglomerate particulate ingredients into homogeneous mixes. The high-frequency vibrations facilitate binding through controlled mechanical action rather than thermal softening, maintaining the structural integrity of individual ingredient particulates while achieving uniform distribution and mixing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method preserves nutritional integrity, reduces energy consumption, and produces a shelf-stable, portable snack with unique appearance and complex shapes, achieving efficient production with minimal assets and space requirements.
Implementation Method 1
The charge is then compressed between an inert anvil punch and an ultrasonically energizable tool by means of an actuator. The ultrasonically energizable tool is then injected with a commensurate amount of energy. Vibrations, acting on the moisture uniformly distributed throughout the charge, transform the moisture at points of contact between particulates into steam.
