Solution Overview

Problem

Existing soluble chocolate powders often fail to fully dissolve in cold diluents, leading to uneven beverage appearance and taste, with existing solutions either affecting the taste or increasing production costs, and there is a need for improved solubility without additives and maintaining flowability for consistent dosing.

Innovation Solution

A method involving the preparation of an aqueous emulsion of cocoa fat with an emulsifier like lecithin, which is sprayed into a fluid bed agglomerator to form agglomerates with chocolate powder ingredients, including sweeteners and protein powders, resulting in a soluble agglomerated chocolate powder with enhanced solubility and flowability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If soluble chocolate powder is used with cold diluent, then beverage preparation is convenient, but dissolution is incomplete leading to residua and non-uniform appearance

Engineering Contradiction:
Improvebeverage preparation convenienceVSAvoiddissolution completeness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-agglomerating the chocolate powder with a binding solution before use. This pre-treatment creates granulated powder with improved wettability and dissolution characteristics, so that when cold diluent is added during beverage preparation, the powder dissolves completely without requiring additional action at the moment of preparation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If additives are added to improve dissolution, then solubility in cold water improves, but beverage taste is affected and production cost increases

Engineering Contradiction:
Improvesolubility in cold waterVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by modifying the physical and chemical parameters of the binding solution used in agglomeration. Specifically, it controls the protein content (1-10% dry basis), fat content (1-20% dry basis), and moisture content (10-50%) of the binding solution to achieve optimal dissolution without adding separate dissolution-enhancing additives, thereby avoiding increased production costs and taste alteration.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If more sugar is added to boost dissolution, then dissolution of chocolate mixes improves, but sugar ratio increases affecting original taste and increasing unnecessary sugar consumption

Engineering Contradiction:
Improvedissolution of chocolate mixesVSAvoidsugar ratio in beverage powder
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent uses a binding solution containing proteins and fats as an intermediary substance to facilitate dissolution. Instead of relying on sugar to boost dissolution, the binding solution acts as a mediator that improves wettability and dissolution characteristics through its specific composition and structure, thereby avoiding the need to increase sugar content in the beverage powder.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If heating is applied just before dissolution, then solubility in cold water improves, but beverage preparation machine complexity increases

Engineering Contradiction:
Improvesolubility in cold waterVSAvoidbeverage preparation machine design
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing the heating and agglomeration process during powder manufacturing rather than at the point of use. The powder is pre-treated with heat and binding solution to achieve optimal dissolution characteristics, eliminating the need for heating equipment in the beverage preparation machine, thereby maintaining device simplicity while improving solubility.

Inventive Principle:
Principle #10Preliminary action
