Low-Temperature Mogul Casting for Starch-Based Confectionery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional mogul process is limited in producing confectionery items with temperature-sensitive ingredients and filled confectionery articles due to the use of hot casting compounds, which restricts the inclusion of additives like chocolate masses, flavors, and vitamins, and results in variations in product quality and equipment issues such as deposits and stringing.
Innovation Solution
A low-temperature mogul process with controlled residence time spectrum is implemented, where swellable or soluble starch particles are mixed with a liquid phase, allowing the starch to swell or dissolve after casting, with specific parameters for residence time spectrum to ensure uniform viscosity and product consistency, enabling the production of confectionery articles with a rubbery texture similar to gelatin without the need for gelatin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot casting compound is used in conventional mogul process, then the casting process can be carried out efficiently, but temperature-sensitive additives cannot be included and product quality varies
Solution Approach 1:
The patent changes the temperature parameter of the casting compound from hot (conventional) to cold (invention), enabling the inclusion of temperature-sensitive additives while maintaining casting efficiency through controlled residence time spectrum
Solution Approach 2:
The starch particles are pre-swollen in a controlled manner before casting, allowing the casting compound to be kept cold while still achieving proper gelling after casting, thus preserving temperature-sensitive ingredients
2Stability of the object's composition
If long-chain starch is used to achieve rubber-elastic texture, then gelatin-like texture is obtained, but the cooked starch produces high viscosity that prevents casting
Solution Approach 1:
The patent segments the starch processing into two distinct stages: pre-swelling of starch particles in a controlled manner before casting, and complete swelling/gelling after casting. This segmentation allows the use of long-chain starch for rubber-elastic texture while maintaining castability during the casting process
Solution Approach 2:
The starch particles undergo preliminary partial swelling before casting, which prepares them for complete gelling after casting without producing excessive viscosity during the casting process itself, thus enabling both castability and rubber-elastic texture
3Manufacturing precision
If small batch sizes are used to reduce viscosity variation, then product consistency improves, but production efficiency decreases and automation becomes difficult
Solution Approach 1:
The patent implements feedback control through precise measurement and control of the residence time spectrum, ensuring that all portions of the casting compound experience similar mixing history. This feedback mechanism maintains product consistency with larger batch sizes by controlling the critical parameter of residence time distribution
Solution Approach 2:
The patent changes the critical parameter from batch size (which would require small batches for consistency) to residence time spectrum characteristics (which can be controlled independently of batch size), enabling both large batch production and consistent product quality
4Ease of manufacture
If conventional mixing processes are used, then the casting compound can be prepared, but deposits occur in channels and stringing occurs during casting
Solution Approach 1:
The patent implements feedback control by measuring and controlling the residence time spectrum of the mixing process, ensuring that all portions of the casting compound experience similar mixing history. This prevents localized over-mixing or under-mixing that would cause deposits and stringing during casting
Solution Approach 2:
The patent changes the critical control parameter from simple mixing time to the full residence time spectrum characteristics, including mean residence time and distribution width. This precise parameter control ensures uniform mixing without causing deposits or stringing

Function Achieved in This Case
This process allows for the production of confectionery items with temperature-sensitive ingredients and filled articles that maintain their shape and quality, reduces equipment issues, and achieves a rubbery texture comparable to gelatin products, while enabling the use of temperature-sensitive additives and reducing operational costs through increased automation.
Implementation Method 1
swellable or soluble starch particles are mixed with a liquid phase, allowing the starch to swell or dissolve after casting
Implementation Method 2
When the casting compound cools in the molds, gelling occurs, which solidifies the moldings
Implementation Method 3
When the casting compound cools in the molds, gelling occurs, which solidifies the moldings

AI summary
In a low temperature casting process for producing confectionary articles on a Mogul unit, wherein swellable or soluble starch particles are mixed in a liquid phase and then this mixture is cast, wherein the starch particles do not swell or dissolve substantially until after casting, characterized in that, after mixing the solid phase with the liquid phase, the residence time of the casting mass is set in such a manner that the maximum tM of the residence time spectrum immediately after mixing the solid phase with the liquid phase is < 10 min and the half width tH of this residence time spectrum is < 10 min. Using this process, in particular filled starch-based gum-type confectionary articles can be produced. These comprise at least one filling and at least one sheath which is different from the filling, wherein the sheath contains at least one sugar and further particles of particulate starch. The confectionary articles preferably have a rubber-elastic texture which is very similar to that of gelatine products, without gelatine needing to be used therefor.
