Coffee Grinder Separation Chamber Cleaning by Air Aspiration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coffee machines with grinders often leave waste such as chaff in the separation area, which can deteriorate the taste of the coffee beverage and adhere to the inner peripheral walls, and existing separation methods are inefficient.
Innovation Solution
A coffee machine with a first grinder and a separation area that is cleaned by wind pressure when the grinder is stopped, utilizing an air aspiration portion to remove waste through strong air aspiration, even after the grinder stops, and a second grinder for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If waste separation is performed during grinder operation, then coffee beans are ground and waste is separated simultaneously, but waste remains in the separation area and adheres to inner peripheral walls
Solution Approach 1:
The air aspiration portion performs preliminary cleaning action by aspirating waste from the separation area before the grinder completes its operation. This preliminary action prevents waste from adhering to inner peripheral walls and ensures complete waste removal, resolving the contradiction between processing efficiency and waste removal completeness.
2Use of energy by moving object
If air aspiration is stopped temporarily during grinder operation, then energy is saved, but cleaning time increases and waste removal is incomplete
Solution Approach 1:
The air aspiration portion operates continuously without temporary stops during the entire grinding process. This continuous operation ensures that waste is constantly aspirated from the separation area, preventing waste accumulation and adhesion, while maintaining energy efficiency through optimized aspiration timing that aligns with the grinding cycle.
3Reliability
If strong air aspiration is applied continuously, then waste is effectively removed from separation area, but energy consumption increases
Solution Approach 1:
The air aspiration portion operates periodically in synchronization with the grinder's operation cycles. Strong aspiration is applied during grinding phases when waste generation occurs, and aspiration intensity is reduced or stopped during idle phases. This periodic action maintains effective waste removal while optimizing energy consumption by avoiding continuous high-intensity operation.
