Food Processor Foreign-Material Trap for Vacuum Pump Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food processors with vacuum exhaust systems are prone to damage due to foreign materials entering the vacuum pump during processing, which existing technologies fail to effectively block.
Innovation Solution
A food processor design incorporating a foreign-material trap unit positioned between the first and second exhaust channels, which prevents foreign materials from entering the vacuum pump by using a gas-liquid separating mechanism and movable components to block solid and liquid foreign materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vacuum exhaust is performed to prevent food oxidation, then food quality is improved, but foreign materials enter the exhaust channel and damage the vacuum pump
Solution Approach 1:
A foreign material trap unit is introduced as an intermediary component between the exhaust channel and vacuum pump. This trap unit captures foreign materials (both solid and liquid) that are drawn in during vacuum exhaust, preventing them from reaching and damaging the vacuum pump while maintaining the vacuum function.
Solution Approach 2:
The exhaust system is segmented into multiple components: the exhaust channel, the foreign material trap unit, and the vacuum pump. This segmentation isolates the foreign material collection function in a separate removable unit, allowing easy maintenance and preventing foreign materials from directly contacting the vacuum pump.
2Reliability
If foreign materials are blocked during vacuum exhaust, then vacuum pump protection is improved, but the device structure becomes more complex
Solution Approach 1:
The foreign material trap unit is designed as a nested structure where collection containers are positioned within the exhaust channel pathway. The trap unit itself is nested within the enclosure, and the removable collection containers are nested within the trap unit housing, creating a compact multi-layered protection system.
Solution Approach 2:
The foreign material collection containers are designed as removable and replaceable components. When filled with foreign materials, these containers can be easily removed and replaced with new ones, avoiding the need to service or replace the entire vacuum pump system and reducing maintenance 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
Effectively blocks both solid and small amounts of liquid foreign materials from entering the vacuum pump, preventing damage and ensuring the vacuum system operates safely and hygienically.
Implementation Method 1
process food after the inside of the container undergoes vacuum exhaust to have a negative pressure environment
Implementation Method 2
a foreign-material trap unit provided between the first exhaust channel and the second exhaust channel and preventing foreign materials introduced into the first exhaust channel from being introduced into the second exhaust channel

AI summary
A cooking device includes: a container having a top opening and a receiving space in which food put into the container through the opening is received; a lid which is detachably coupled to the container so as to open and close the opening, and has a first vent channel communicating with the receiving space; an enclosure which is provided to at least partially enclose the container and the lid, and has a second vent channel communicating with the first vent channel; a vacuum pump connected to the second vent channel; and a foreign matter trapping unit which is provided between the first and second vent channels to prevent foreign matter, introduced into the first vent channel in the process of venting gas in the receiving space by the vacuum pump, from being introduced into the second vent channel.
