Bayonet Coffee Roaster Chamber Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee bean roasting apparatuses with fluidized bed technology require frequent greasing and cleaning of the chamber locking mechanism due to high temperatures and dust deposition, making operations inconvenient and inefficient.
Innovation Solution
A bayonet-style chamber locking assembly with a removable fixing device and support system that allows for easy access and maintenance, enabling the chamber to be cleaned and greased outside the apparatus, with a gas-tight sealing mechanism to prevent smoke escape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional clamp mechanism with screwing parts is used for the chamber locking assembly, then the chamber can be securely fastened to the housing, but the screwing parts require frequent greasing and cleaning due to high temperature and dust deposition, making maintenance inconvenient
Solution Approach 1:
The patent replaces the traditional screw-based mechanical locking mechanism with a bayonet-style insertion system. The chamber locking assembly features a simple insertion and rotation mechanism that eliminates complex screwing parts, thereby removing the need for frequent greasing and cleaning while maintaining secure fastening of the chamber to the housing.
2Reliability
If the chamber locking mechanism uses complex screwing parts, then secure connection is achieved, but access to these parts for greasing and cleaning is narrow and inconvenient
Solution Approach 1:
The chamber locking assembly is designed as a segmented system with the chamber locking mechanism separated from the chamber body. The locking assembly includes an insertion portion that fits into the chamber and a separate operation portion that can be accessed from outside the apparatus, allowing maintenance without disassembling the chamber or accessing narrow internal spaces.
3Productivity
If the chamber is tightly connected to the housing during operation, then roasting efficiency is improved, but the chamber must be completely disassembled for cleaning and maintenance
Solution Approach 1:
The chamber locking assembly employs a dynamic locking mechanism that can be quickly engaged and disengaged. The bayonet-style insertion and rotation system allows the chamber to be rapidly secured during operation for efficient roasting, and just as rapidly removed for cleaning, eliminating the time-consuming complete disassembly required by traditional fixed connections.
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 simplifies the locking and maintenance process, reducing the need for frequent greasing and cleaning, enhancing operational efficiency and safety by allowing all parts to be easily accessed and maintained without compromising the roasting process.
Implementation Method 1
Another type of apparatus uses fluidized bed technology implementing a hot air fluid bed chamber. Within such a chamber, heated air is forced through a screen or a perforated plate under the coffee beans with sufficient force to lift the beans.
Implementation Method 2
Heat is transferred to the beans as they tumble and circulate within this fluidized bed.
