Coffee Roaster Distributing Device for Chaff and Bean Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small-scale coffee bean roasting apparatuses are cumbersome for successive roasting operations and lack efficient automatic collection of chaffs and roasted beans, making it difficult to prepare coffee for multiple customers simultaneously.
Innovation Solution
A roasting apparatus with a roasting chamber, air driver, heater, chaff collector, and beans collector, featuring a distributing device that allows independent operation of the chaff and beans collectors through separate channels, enabling automatic separation and storage of roasted beans in different containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single channel is used for both chaff evacuation and roasted beans evacuation, then the apparatus structure is simplified, but the operation becomes cumbersome requiring manual separation and reassembly
Solution Approach 1:
The single channel is divided into two separate channels: a first channel for chaff evacuation and a second channel for roasted beans evacuation. This segmentation allows independent operation of each channel, enabling successive roasting operations without manual reassembly while maintaining structural simplicity.
2Device complexity
If the same channel is used for both chaff and beans evacuation, then the device structure is simpler, but automatic collection of chaffs and roasted beans becomes difficult
Solution Approach 1:
The channel is segmented into a first channel connected to a chaff collector and a second channel connected to a beans collector. This allows automatic collection of chaffs and roasted beans in separate containers, eliminating manual intervention while keeping the overall device structure simple.
Solution Approach 2:
A distributing device acts as an intermediary between the roasting chamber and the two collectors. It automatically directs chaffs through the first channel to the chaff collector and roasted beans through the second channel to the beans collector, enabling automatic separation and collection.
3Device complexity
If chaffs and roasted beans are collected in the same cyclone device, then the separation function is achieved, but manual separation operations are required
Solution Approach 1:
Instead of using a single cyclone device for both chaffs and roasted beans, the system uses two separate collection channels leading to separate collectors. This segmentation eliminates the need for manual separation operations while maintaining the separation function, allowing continuous successive roasting operations.
4Device complexity
If a single collector is used for both chaffs and roasted beans, then the device structure is simpler, but successive roasting operations for multiple customers become inefficient
Solution Approach 1:
The single collector is segmented into two separate collectors: a chaff collector and a beans collector. This allows simultaneous or successive roasting operations for multiple customers without requiring emptying and reassembly, significantly improving productivity while keeping each collector simple in structure.
Solution Approach 2:
The distributing device provides multi-functionality by automatically directing different materials (chaffs and roasted beans) to different collectors based on the roasting stage, enabling the system to handle multiple customer orders efficiently without increasing collector complexity.
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
Facilitates more automated and practical roasting operations, allowing for the roasting of different types of coffee beans and their separate storage, reducing manual effort and enabling efficient preparation of coffee for multiple customers.
Implementation Method 1
The chamber is preferably designed to enable the production of a fluidized bed of hot air
Implementation Method 2
The apparatus comprises a heater, preferably electrical, configured to heat the flow of air before it is introduced inside the roasting chamber
Implementation Method 3
The chaffs and the beans are collected in a cyclone device enabling the separation of the heavy roasted coffee beans from the light chaffs
