Parallel Centrifugal Separators for Fat Extraction Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fat separation methods in the food industry, particularly in milk and whey processing, require multiple separators to achieve efficient fat extraction, leading to high capital and operational costs, and do not effectively maximize fat yield.
Innovation Solution
A method involving two or more centrifugal separators connected in parallel, where the lighter phase from the first separator is fed into the inlet of the second, regulating the first separator to ensure the lighter phase has a fat content of less than 15%, thereby increasing the fat content entering the second separator and enhancing fat separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If larger separators are used to increase fat extraction yield, then fat separation efficiency is improved, but capital costs and operational costs increase
Solution Approach 1:
The patent divides the fat separation process into multiple stages by using several separators connected in parallel, each handling a portion of the incoming liquid food product. This segmentation allows the system to achieve high total fat extraction yield without requiring any single separator to be excessively large, thereby reducing capital costs and operational costs while maintaining high productivity.
2Productivity
If multiple separators are used in series to increase fat yield, then fat separation efficiency is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple separators into a parallel configuration where each separator processes a portion of the feed stream simultaneously. The lighter phases from all separators are combined and fed to a single second separator for further fat extraction. This merging approach achieves high overall fat yield while minimizing the total number of separators required, as the second separator consolidates the fat extraction function.
Solution Approach 2:
The patent transitions from a traditional series arrangement to a parallel-dimension arrangement where multiple separators operate simultaneously on parallel streams. This dimensional change allows the system to achieve the same or better fat extraction yield with fewer total separators, reducing device complexity and cost while maintaining high productivity.
3Manufacturing precision
If the first separator is regulated for low fat content in lighter phase, then separation precision is improved, but productivity may be reduced
Solution Approach 1:
The patent segments the fat extraction function across multiple separators in parallel, allowing each separator to be optimized for precise fat content control in its lighter phase. By dividing the total processing load across multiple units, the system maintains high separation precision while preserving overall processing capacity, as each separator operates independently at optimal conditions.

Function Achieved in This Case
This approach increases fat separation by 5-10% with a lower residual fat content in the heavier phase, reducing investment and operational costs and providing a valuable raw material for protein extraction, especially in whey processing.
Implementation Method 1
the product is divided up into a lighter phase and a heavier phase in a centrifugal separator... the product arrives from the inlet into the separation section proper and is subjected to centrifugal force

AI summary
A method of improving the efficiency of fat separation in the separation of a liquid food product with a certain fat content. The method comprises the liquid food product is caused to pass two separators connected in parallel, a first and a second, in which the product is divided up into a lighter and a heavier phase. The first separator is regulated so that the lighter phase will have a fat content which is less than 15%. The lighter phase from the first of the separators connected in parallel is led into the inlet conduit to the second of the separators connected in parallel.
