Solution Overview

Problem

Existing separators used for sterilizing milk face inefficiencies due to pressure increases from partial emptying, tank switching, and increased air content, which can lead to reduced sterilization efficiency and germ transport to the peeling disc.

Innovation Solution

The implementation of a ribbed body with curved, blade-like design in the inlet area of the separator, which reduces inlet pressure and increases inlet capacity, ensuring a gentle product feed and minimizing deposit formation, while maintaining uniform venting even with high air content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stress or pressure

If a conventional inlet design is used, then the structure is simple, but inlet pressure increases and inlet capacity decreases

Engineering Contradiction:
Improveinlet pressureVSAvoidinlet capacity
Core Design Contradiction:
Stress or pressureVSProductivity

Solution Approach 1:

The patent applies curved, blade-like ribs with specific curvatures in all spatial directions to the inlet distributor. These curved surfaces guide the fluid flow more efficiently, reducing pressure losses and increasing inlet capacity while maintaining structural simplicity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The inlet distributor is segmented into multiple blade-like ribs that are distributed around the inlet area. This segmentation allows each rib to independently guide flow in its local region, collectively achieving uniform pressure distribution and enhanced overall inlet capacity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the inlet pressure is reduced, then the product feed becomes more gentle, but the feed rate may decrease

Engineering Contradiction:
Improveproduct feed gentlenessVSAvoidfeed rate
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The curved blade-like ribs create a gentler flow path that reduces turbulence and shock during product feed, while the optimized curvature geometry maintains high flow velocity and feed rate simultaneously.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent optimizes the curvature parameters and spatial orientation of the ribs to achieve the right balance between gentle feed (reduced pressure) and high feed rate (maintained flow capacity).

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the inlet area structure is simplified, then manufacturing is easier, but deposit formation risk increases

Engineering Contradiction:
Improveinlet area structureVSAvoiddeposit formation risk
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The curved blade-like ribs eliminate sharp corners and stagnant zones in the inlet area, creating smooth flow paths that prevent deposit formation. The continuous curved surfaces are easy to manufacture while effectively reducing contamination risk.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Reliability

If uniform venting is achieved with high air content, then sterilization efficiency is maintained, but the system complexity increases

Engineering Contradiction:
Improvesterilization efficiencyVSAvoidinlet distributor structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The segmented rib structure distributes venting uniformly across the inlet area, handling high air content effectively while keeping the overall system design simple and manufacturable.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a separator comprising a centrifugal drum (1) into which a product to be processed, especially milk, can be guided through an admission tube (7) and an admission chamber (12) arranged downstream of the tube and comprising outlets in admission boreholes (8), which lead to a centrifugal chamber in the centrifugal drum (1). A rib (15) is associated with at least one or each outlet (14) from the admission chamber (12) to the admission boreholes (8) of the distributor (5). The separator is characterised in that the ribs (15) are part of a rib body (14) that comprises a plurality of the ribs and a base section (16) connecting the ribs (15) in the peripheral direction.
