Solution Overview

Problem

Current tempering machines for confectionery masses, such as chocolate, require complex settings of individual controllers for temperature and quantity, making it difficult to directly adjust the degree of tempering, which is essential for processing chocolate masses effectively.

Innovation Solution

A method and device that allow for direct adjustability of the tempering degree by setting only one variable, the desired temperature degree, using a control device with a temperature measuring device and programmable logic controller, which automatically adjusts parameters like temperature and volume flow of the cooling medium over a defined time interval to achieve the desired tempering index.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If individual controllers for temperature and quantity are adjusted manually, then the tempering degree can be controlled, but the operation complexity increases significantly

Engineering Contradiction:
Improvetempering degree controlVSAvoidoperation complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent transforms multiple control parameters (temperatures of mass and tempering media, quantities) into a single control parameter (desired tempering level). The control unit automatically calculates and adjusts the individual controller settings based on the desired tempering level, eliminating the need for manual adjustment of multiple parameters while maintaining precise tempering control.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The control unit acts as an intermediary between the operator and the individual controllers. Instead of directly adjusting multiple temperature and quantity controllers, the operator simply inputs the desired tempering level, and the control unit mediates by automatically determining the appropriate settings for all individual controllers.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple parameters are adjusted manually to achieve desired tempering level, then tempering control is possible, but the adjustment process becomes time-consuming

Engineering Contradiction:
Improvetempering level accuracyVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The control unit is pre-programmed with the relationships between desired tempering levels and the required settings for individual controllers. When an operator inputs a desired tempering level, the control unit immediately retrieves and applies the pre-calculated settings, eliminating the time-consuming trial-and-error adjustment process while ensuring accurate tempering control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the actual tempering level and compares it with the desired level. The control unit automatically adjusts the individual controllers based on this feedback, enabling rapid convergence to the target tempering level without manual intervention and reducing the overall adjustment time.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If automatic control system is implemented, then operation is simplified, but the initial setup and programming complexity increases

Engineering Contradiction:
Improveoperation simplicityVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control unit is designed to automatically determine the settings for individual controllers based on the desired tempering level input by the operator. The system serves itself by internally calculating and adjusting all necessary parameters without requiring external expertise or complex manual configuration, thereby simplifying operation while managing control system complexity through automated self-adjustment.

Inventive Principle:
Principle #25Self-service
