Extraction apparatus and extraction method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction apparatuses face challenges in removing air from the extraction process without decreasing the concentration of the extraction liquid, leading to hindered extraction efficiency.
Innovation Solution
The apparatus includes an exhaust unit below the placement unit to discharge gas outward from the accommodation chamber, ensuring the extraction liquid is not diluted by solvent fed into the pipe or tank, and a control device to manage the operation of various components for efficient extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the discharge pump is reversely rotated to feed solvent into the pipe for removing air, then the air inside the pipe is removed, but the extraction liquid concentration decreases due to solvent dilution
Solution Approach 1:
The invention extracts the harmful air from the system through a dedicated exhaust unit that is separate from the solvent feed path. The exhaust unit includes an exhaust port positioned below the placement unit that allows air to be removed without requiring reverse pumping of solvent, thereby preventing dilution of the extraction liquid.
Solution Approach 2:
The invention segments the air removal function from the solvent feed system. Instead of using the discharge pump for both solvent feeding and air removal, a separate exhaust unit with its own exhaust port is introduced specifically for air evacuation, allowing independent optimization of each function.
2Object-affected harmful factors
If the discharge pump is used to remove air by reverse rotation, then the air removal function is achieved, but the device complexity increases due to additional operations
Solution Approach 1:
The exhaust unit is prepared in advance with the exhaust port positioned below the placement unit, allowing air to be removed naturally during the extraction process setup. This preliminary arrangement eliminates the need for complex reverse rotation operations of the discharge pump.
Solution Approach 2:
The system allows air to be removed automatically through the exhaust port during normal operation. The exhaust unit works passively to evacuate air as the solvent flows through the system, without requiring active intervention or complex pump operations.
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
This approach allows for the removal of air without reducing the concentration of the extraction liquid, resulting in a higher concentration of the extracted liquid compared to traditional methods and automating the process to save labor.
Implementation Method 1
an exhaust unit provided below the placement unit so that gas is exhausted outward of the accommodation chamber
Implementation Method 2
the solvent permeates the raw material, and thereafter, the extraction liquid is accumulated
Implementation Method 3
the solvent permeates the raw material
