Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meat processing machinery is limited by high centrifugal forces and vibrations when processing large meat masses, restricting rotational speed and preventing the production of fine meat pastes or emulsions, especially in whole muscle products.
Innovation Solution
A rotary drum machine with adjustable height and vibration damping means, allowing rotational speeds up to 24 rpm and capable of processing 500 kg to 10,000 kg meat masses, featuring fluid dynamic cylinders and elastic elements to absorb vibrations, enabling high-yield hams and cold cuts production without compromising whole muscle appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotary drum rotates at high speed to reduce kneading time, then productivity is improved, but vibrations and centrifugal forces increase causing machine instability
Solution Approach 1:
The patent applies beforehand cushioning by installing vibration damping means (elastic elements and fluid dynamic cylinders) on the support chassis before the drum operates at high speed. These damping elements are pre-positioned to absorb and dissipate vibrations generated during high-speed rotation, allowing the drum to rotate at speeds up to 24 rpm without transmitting excessive vibrations to the machine structure, thus enabling reduced kneading times while maintaining machine stability.
2Quantity of substance
If the drum weight and meat mass increase to process larger quantities, then productivity is improved, but centrifugal forces increase limiting maximum rotational speed
Solution Approach 1:
The patent applies pneumatics and hydraulics by incorporating fluid dynamic cylinders as part of the vibration damping system. These cylinders use fluid dynamics to provide damping forces that counteract the centrifugal forces generated during rotation. When the drum rotates at high speed with large meat masses (500-10,000 kg), the fluid dynamic cylinders absorb and dissipate the centrifugal forces and vibrations, allowing the system to maintain rotational speeds up to 24 rpm despite processing large quantities of meat.
3Reliability
If vibration damping means are added to reduce vibrations, then machine stability is improved, but device complexity increases
Solution Approach 1:
The patent applies flexible shells and thin films by using elastic elements (such as rubber or polymer dampers) as part of the vibration damping system. These elastic elements are flexible components that absorb vibrations through deformation. They are integrated into the support chassis structure, providing vibration damping without requiring complex mechanical systems. The elastic elements flex and dissipate energy, maintaining machine stability while adding minimal structural complexity.
