Solution Overview

Problem

Current methods for preparing dextrose compositions for pharmaceutical or food formulations lack sufficient flowability, friability, and compressibility, making them inefficient and costly to produce, especially when direct compression methods are not feasible due to the nature of active ingredients.

Innovation Solution

A dry granulation process involving roller compaction or slugging of a high-dextrose composition, followed by crushing and screening to produce granules with specific particle size distribution, enhancing the dextrose's compressibility and flowability, allowing for the production of tablets with higher hardness and reduced friability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If direct compression method is used, then production steps are reduced, but the method is only employable if ingredients have good flow properties and compaction characteristics

Engineering Contradiction:

Solution Approach 1:

The invention changes the physical parameters of dextrose by converting it from crystalline form to amorphous form through melt granulation. This parameter change transforms the flow and compaction properties of dextrose, making it suitable for direct compression methods that were previously not applicable to crystalline dextrose.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention utilizes phase transition of dextrose from solid crystalline state to molten state and then to amorphous solid state. This phase transition process fundamentally alters the material properties, enabling direct compression while maintaining versatility with different active ingredients.

Inventive Principle:
Principle #36Phase transitions

2Manufacturing precision

If granulation method is used to improve flow and compaction properties, then tablet quality is improved, but the process becomes more complex and costly

Engineering Contradiction:
