Fat Powder Pulverization Preventing Clumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pulverizing fat substances often result in clogged rotary valves and clumping of the obtained fat powder, which complicates the process and reduces reliability.
Innovation Solution
A device comprising a chamber, nozzle, and stirrer with pulverizing means using liquid nitrogen, where the fat is sprayed into the chamber, cooled to form a powder, and then stirred within a separate stirrer to prevent clumping and ensure reliable pulverization, with features like annular pulverizing nozzles, a cooling installation, and an exhaust system to manage coolant residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotary valve is used to extract fat powder from the chamber, then the fat powder can be extracted, but the rotary valve becomes clogged and the fat powder clumps
Solution Approach 1:
The harmful effect of rotary valve clogging is eliminated by removing the rotary valve from the system. The patent extracts the fat powder from the chamber through a valveless design where the stirred powder flows directly from the spray chamber into the collection container, preventing clogging at the extraction point
Solution Approach 2:
The stirrer acts as an intermediary device that prevents fat powder clumping by continuously agitating the powder in the chamber. This intermediary action maintains powder flowability and prevents aggregation that would otherwise cause clogging during extraction
2Manufacturing precision
If liquid nitrogen is used to pulverize the substance, then the substance is frozen and pulverized, but the obtained powder clumps
Solution Approach 1:
The stirrer provides continuous mechanical action on the pulverized powder, preventing clumping by maintaining constant movement and preventing particle aggregation. This continuous stirring action persists throughout the extraction process, ensuring powder stability
Solution Approach 2:
The system transitions from a static pulverization process to a dynamic one by introducing continuous stirring. The powder is not merely frozen and extracted, but actively agitated during the entire process, changing its physical state from static to dynamically maintained flowability
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
The solution effectively prevents clumping and ensures reliable pulverization of fat substances by isolating the powder from the atmosphere during transfer and using cooling and stirring to stabilize the powder, enhancing the process's reliability and efficiency.
Implementation Method 1
