Solution Overview

Problem

Existing chocolate manufacturing processes struggle to produce solid chocolate nuggets with microalgae that are less than 10 mm in diameter due to viscosity issues, and they fail to prevent color diffusion of microalgae during cooking.

Innovation Solution

A process involving precise temperature control and an overpressure step during chocolate pouring, combined with the use of a coating agent, to create chocolate nuggets with microalgae that maintain their color and size consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If conventional chocolate manufacturing processes are used, then chocolate can be produced, but chocolate nuggets with microalgae less than 10 mm in diameter cannot be produced due to viscosity issues

Engineering Contradiction:
Improvediameter of chocolate nuggetsVSAvoidviscosity of chocolate-microalgae mixture
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by precisely controlling the temperature of the chocolate-microalgae mixture at 33°C during the casting process. This specific temperature parameter optimization reduces the viscosity of the mixture, enabling it to be properly cast into small nugget forms less than 10 mm in diameter that were previously unachievable with conventional processes

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses an overpressure step during the casting process to facilitate the flow and proper formation of the chocolate-microalgane mixture into small nuggets. The applied pressure overcomes the viscosity resistance and enables successful casting of small-diameter chocolate chips containing microalgae

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Productivity

If chocolate chips with microalgae are produced using conventional processes, then chocolate chips can be manufactured, but the color of microalgae diffuses from the chocolate chip to the rest of the matrix during cooking

Engineering Contradiction:
Improvemanufacturing of chocolate chipsVSAvoidcolor diffusion of microalgae
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a coating agent as an intermediary layer between the microalgae-containing chocolate core and the surrounding cooking matrix. This coating layer acts as a barrier that prevents the diffusion of microalgae color and compounds into the surrounding food matrix during cooking, while still allowing the chocolate chips to be manufactured using conventional processes

Inventive Principle:
Principle #24Intermediary (Mediator)

3Length of moving object

If precise temperature control and overpressure step are applied, then small chocolate chips with microalgae can be cast, but the process complexity increases

Engineering Contradiction:
Improvediameter of chocolate chipsVSAvoidtemperature and pressure control system
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent optimizes specific parameters (temperature at 33°C and applied pressure) to achieve the desired outcome of casting small chocolate chips. By precisely setting and maintaining these parameter values, the process becomes more controllable and reproducible, justifying the increased device complexity through consistent production of small-diameter chocolate chips with microalgae

Inventive Principle:
Principle #35Parameter changes

AI summary

The present patent application relates to a method for manufacturing chocolate chips comprising microalgae, the chocolate chips and the use of said chocolate chips. The method enables perfect incorporation of the microalgae through the use of a precise temperature and the pouring of small-sized chocolate chips by means of a pressure boosting step at the time of pouring. A coating agent is also introduced in order to solve the problem of microalgae colour diffusion. These chocolate chips are ideal for use in food preparations, for example in cookies, cereal bars, toppings, or mueslis.
