Central Utility Milking Layout for Cleaning Without Downtime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milking systems face inefficiencies in milk quality maintenance and production due to synchronized cleaning cycles that render all devices unavailable for milking, increased barn area requirements, and longer milk transport distances, which affect milk quality and production efficiency.
Innovation Solution
A milking system with a central utility system comprising multiple milking devices, a buffer unit for temporary milk storage, an individual cleaning unit, and a control unit that allows for simultaneous milk extraction and cleaning of individual devices during scheduled cleaning cycles, using a centralized vacuum and cleaning fluid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronized cleaning cycles are used for multiple milking devices, then all devices are cleaned simultaneously ensuring hygiene, but all devices become unavailable for milking during the cleaning cycle reducing productivity
Solution Approach 1:
The cleaning process is segmented into individual device cleaning cycles rather than synchronized cluster cleaning. Each milking device can be cleaned independently while others remain operational, allowing continuous milk production without complete system shutdown
Solution Approach 2:
The system dynamically assigns cleaning tasks to individual devices based on availability and operational status. The control system manages flexible scheduling where devices transition between cleaning and milking modes independently, optimizing both hygiene and productivity
2Productivity
If multiple milking devices are deployed to handle larger herds, then milking capacity increases, but barn area increases and milk transport distance increases affecting milk quality
Solution Approach 1:
Multiple milking devices share common infrastructure including milk lines, cleaning systems, and control units. This consolidation reduces the need for additional barn space and minimizes milk transport distances while maintaining increased milking capacity through efficient resource sharing
Solution Approach 2:
The system design allows single milk lines and utility systems to serve multiple milking devices simultaneously. This multi-functional approach enables larger herd capacity without proportionally increasing barn area or transport infrastructure
3Ease of operation
If individual cleaning units are provided for each milking device, then cleaning can be performed independently, but device complexity and system cost increase
Solution Approach 1:
The cleaning system is segmented into modular individual units that can be assigned to specific devices as needed. This allows independent cleaning operation while maintaining system simplicity through on-demand allocation rather than permanent dedicated infrastructure for each device
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
Enables continuous milk extraction by maintaining at least one device available for milking during cleaning cycles, improving milk quality and production efficiency by reducing cleaning synchronization issues and optimizing energy use.
Implementation Method 1
the cleaning unit comprises at least one fluid transporting line for transport of cleaning fluid
Implementation Method 2
a buffer unit for receiving and temporarily storing extracted milk, wherein the buffer unit is in fluid connection with each of the milking devices through a milk line
Implementation Method 3
the cleaning unit cleans each of the milking devices and respective milk lines individually during a cleaning cycle

AI summary
A milking system includes two or more milking devices for extracting a milking from a dairy animal; a central utility system connected with each milking device in the milking system, and a cleaning unit for cleaning the milking devices and milk-carrying parts of the central utility system. The cleaning unit includes a fluid transporting line for transport of cleaning fluid where each of the milking devices is in fluid connection with the fluid transport line, a buffer unit for receiving and temporarily storing extracted milk where the buffer unit is in fluid connection with each of the milking devices through a milk line, and a control unit for controlling the central utility unit. The cleaning unit cleans each milking device and milk line during a cleaning cycle, and at least one of the milking devices is available for extracting milk from a dairy animal during the cleaning cycle.
