Coffee Chaff Cutting and Cyclone Separation for Cleaner Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee bean grinder devices face challenges in separating coffee beans and chaff efficiently due to heat generation during grinding, leading to impure tastes and difficulty in cleaning, while conventional chaff separation is cumbersome and affects coffee aroma and taste.
Innovation Solution
A coffee chaff cutting device with a cutting machine and cyclone separator using vacuum pressure, equipped with first, second, and third separating plates of different lengths and external air inflow, to separate coffee beans and chaff efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If coffee beans are finely ground using conventional grinder devices, then coffee bean powder at desired particle size is obtained, but heat is generated causing shell to fuse with cell membrane and coffee particles, making it difficult to separate coffee beans and shell
Solution Approach 1:
The invention divides the processing into two distinct stages: first cutting the shell to separate it from the coffee bean, then grinding only the separated coffee bean. This segmentation prevents the shell from fusing with the bean during grinding by eliminating the shell component before the grinding operation.
Solution Approach 2:
The shell cutting operation is performed as a preliminary action before the grinding process. By pre-cutting and separating the shell, the subsequent grinding operation only processes the coffee bean, preventing heat-induced fusion between shell and bean components.
2Productivity
If conventional grinder devices are used to grind coffee beans, then coffee bean powder is produced, but many inner shells and center cuts remain mixed with ground coffee beans, reducing unique flavor
Solution Approach 1:
The invention segments the processing steps into shell cutting and separation, followed by bean grinding. This segmentation ensures that only separated coffee beans undergo grinding, eliminating mixed inner shells and center cuts from the final ground coffee.
Solution Approach 2:
The shell and unwanted center cuts are extracted and removed from the coffee bean before grinding. The separation mechanism extracts these impurities, allowing only pure coffee beans to be ground, thus maintaining flavor quality.
3Device complexity
If light chaff is separated from coffee beans and blown inside the separator, then separation process is simplified, but difficulty arises in separating chaff and coffee beans and cleaning the inside of the cutter
Solution Approach 1:
The chaff is extracted and removed from the coffee bean through the cutting and separation mechanisms. By taking out the chaff before grinding, the separator and cutter remain cleaner, reducing cleaning difficulties while maintaining a relatively simple separation process.
