Sensor-Guided Milk Tank Switching for Milking Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milking systems face challenges in reducing the amount of discarded milk due to milk quality issues, such as temperature deviations and contamination, leading to lower milk production yield.
Innovation Solution
A milking system equipped with sensors to monitor milk properties and cooling system functionality, allowing for real-time redirection of milk to a secondary tank if quality deviations are detected, ensuring milk quality is maintained and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time monitoring of milk properties is implemented, then milk quality is maintained and discarded milk is reduced, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The sensor detects milk properties (temperature, conductivity, turbidity) in real-time as milk flows through the transport conduit, enabling early detection of quality deviations before the milk reaches the tank. This preliminary detection allows the control device to redirect milk to an alternative tank before contamination or quality degradation occurs, maintaining milk quality without requiring complex post-processing systems.
Solution Approach 2:
The controllable valve arrangement acts as an intermediary component that redirects milk flow between tanks based on sensor feedback. When quality deviations are detected, the valve automatically switches the milk flow path to an alternative tank, preventing compromised milk from contaminating the main storage tank. This intermediary mechanism resolves the complexity issue by providing a simple, automated flow control solution.
2Reliability
If multiple tanks and redirection systems are used, then milk quality control is improved and discarded milk is reduced, but loss of time occurs during tank switching and monitoring
Solution Approach 1:
The sensor continuously monitors milk properties and provides real-time feedback to the control device. When a quality deviation is detected (such as temperature change, conductivity change, or turbidity increase), the control device immediately responds by actuating the controllable valve to redirect milk flow. This closed-loop feedback system eliminates manual inspection time and enables automatic, real-time quality control without significant time loss.
Solution Approach 2:
The system maintains continuous milk flow and cooling throughout the process. The sensor monitoring and valve redirection occur without interrupting the overall milk transport and cooling operation. Milk is continuously cooled in both tanks, and the redirection is a seamless automated process that maintains the continuity of the useful action (milk cooling and transport) while preventing quality degradation.
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
The system effectively reduces discarded milk by maintaining milk quality, enhancing milk production yield through real-time monitoring and redirection.
Implementation Method 1
tanks are provided with a cooling arrangement comprising a cooling system via which the heat is transferred from the milk to the cooling system
Implementation Method 2
The milk may have a temperature of approximately 37° C. when leaving the milking stations and should have a temperature of approximately 4° C. in the tank
Implementation Method 3
milk properties such as electric conductivity and turbidity, which may be used as indicators of the condition of the milk

AI summary
A milking system configured to milk animals includes a milking station, a first milk tank, and a second milk tank, a controllable valve arrangement configured to open or close a first branch and to open or close a second branch of a milk transport conduit, to control to which tank that milk is transported, and a control device configured to control the controllable valve arrangement. The milking system includes a sensor configured to sense a property of milk present in the first milk tank or of milk flowing towards the first milk tank, or a sensor configured to sense a property of a cooling arrangement for controlling the temperature of the milk in the first milk tank. The control device is configured to control the controllable valve arrangement based on information from the sensor.
