Solution Overview

Problem

The crystallization process for producing metal lactates like zinc and magnesium lactate is costly, complex, and results in products with unfavorable properties such as poor flowability, stickiness, and dustiness, leading to handling and transportation issues, along with significant yield losses.

Innovation Solution

A spray-drying process is used to produce metal lactate powders, which eliminates the need for auxiliary materials and complex processing steps, allowing for control over product properties and reducing waste, resulting in a stable, free-flowing, and less dusty product with improved handling and application suitability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If crystallization process is used to produce metal lactates, then metal lactate product is obtained, but the process is costly and complex with high product losses

Engineering Contradiction:
Improveproduct yieldVSAvoidprocess complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex crystallization process steps (liquid-solid separation, washing, drying, mother liquid treatment) by using a direct spray-drying method that produces the final powder product without these intermediate steps, thereby reducing process complexity and increasing product yield

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical crystallization and filtration system with a thermal spray-drying system that uses heated gas to evaporate solvent and form powder directly, eliminating the need for mechanical separation equipment and reducing overall process complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If crystallization process is used to produce metal lactates, then metal lactate product is obtained, but the product has poor flowability and is sticky and dusty

Engineering Contradiction:
ImproveflowabilityVSAvoidproduct stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent changes the physical parameters of the product by controlling spray-drying conditions (temperature, pressure, feed rate) to produce powder with optimized particle size distribution, moisture content, and density, resulting in improved flowability and reduced stickiness and dustiness compared to crystallized products

Inventive Principle:
Principle #35Parameter changes

3Loss of substance

If crystallization process is used to produce metal lactates, then metal lactate product is obtained, but significant amounts of product are lost in handling and transportation

Engineering Contradiction:
Improveproduct lossVSAvoidhandling ease
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The patent converts the potential harm of product loss during handling into a benefit by producing a powder product with inherently better flow properties through spray-drying, where the controlled particle morphology and reduced dustiness minimize losses during handling and transportation operations

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Productivity

If crystallization process is used to produce metal lactates, then metal lactate product is obtained, but additional expensive and time-consuming processing steps are required for cleaning equipment

Engineering Contradiction:
Improveproduction efficiencyVSAvoidcleaning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent extracts and eliminates the cleaning step from the process by using spray-drying, which produces a powder product that does not require the same extensive washing and cleaning operations as crystallization processes, thereby reducing production time and increasing efficiency

Inventive Principle:
Principle #2Taking out (Extraction)
