Solution Overview

Problem

Current milk transfer systems from bulk storage tanks to transport vehicles are inefficient, requiring significant time and labor, especially as dairy farms produce larger volumes of milk, and existing systems are not adaptable for sanitizing operations.

Innovation Solution

A system utilizing a permanently positioned centrifugal pump with a motor, air-purge system, and a sanitizing wash system to efficiently transfer milk between bulk tanks and transport vehicles, reducing transfer time and integrating sanitizing processes without significant modifications to existing equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a positive-displacement pump on the transport truck is used to transfer milk from the bulk tank, then the milk transfer can be completed, but the transfer time is excessive (about 35 minutes) and the system is not adaptable for sanitizing operations

Engineering Contradiction:
Improvemilk transfer rateVSAvoidtotal process time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines the milk transfer pump and the bulk tank washer into a single integrated system. The pump can operate in two modes: transferring milk from the bulk tank to the truck, and circulating wash solution through the bulk tank for cleaning. This eliminates the need for separate equipment and reduces total process time by allowing seamless transition between transfer and sanitizing operations without disconnection or reconfiguration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pump system is designed to perform multiple functions: it can transfer milk from the bulk tank to the transport truck, and it can also circulate wash solution through the bulk tank for sanitizing operations. This multi-functionality is achieved through a single integrated pump unit that can operate in different modes, eliminating the need for separate dedicated equipment for each function and significantly reducing the overall time required for both transfer and cleaning operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the bulk tank washer is started after milk transfer, then sanitizing can be performed, but this sequential operation increases the total time required

Engineering Contradiction:
Improvesanitizing completenessVSAvoidtotal process time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The integrated pump system allows continuous operation without interruption between milk transfer and sanitizing modes. After completing the milk transfer, the pump can immediately switch to circulate wash solution through the bulk tank for cleaning, eliminating the downtime and disconnection required in traditional sequential systems. This continuous operation maintains sanitizing effectiveness while significantly reducing total process time.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If separate wash pumps and wash tanks are used for sanitizing operations, then thorough cleaning can be achieved, but the device complexity increases

Engineering Contradiction:

AI summary

The invention relates to a system for transferring a liquid consumable product, such as milk, from a bulk storage tank to a transport vehicle receiving tank or from one bulk tank to another whether stationary or mobile. The system increases the efficiency with which the milk is transferred from the bulk tank to the transport vehicle by providing a centrifugal pump permanently positioned on the milk producer's premises proximal the bulk tank. The system includes an air-purge system for removing any residual milk from the pump and transfer lines once pumping has ceased, as well as a wash system for cleaning the pump system components after use. In addition to transferring milk from the bulk tank to the transport truck, the centrifugal pump is conveniently adaptable for use in the washing operations, thereby adding to the efficiency of the overall system.
