Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of isomalt in hard panned coatings for chewing gum is challenging due to stickiness issues, leading to high waste levels and inefficient processing, with existing methods failing to provide a hard coating with good color and crunchy texture while being economically viable.
Innovation Solution
A method using a drum coating system with a surfactant and coating binder in the isomalt coating syrup, applied in thin layers and dried between applications, to reduce stickiness and improve the coating process efficiency, incorporating a surfactant with an HLB value greater than 10 and a coating binder like gum arabic, along with proper heating to enhance wettability and surface tension reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If isomalt is used as hard coating material, then coating cost is reduced and color appearance is improved, but coating stickiness increases causing cores to adhere to drum surface
Solution Approach 1:
The patent introduces an intermediary substance (release agent or modified coating formulation) between the isomalt coating and the drum surface to prevent direct adhesion. This mediator allows the coating to be applied effectively while preventing the harmful sticking effect, resolving the contradiction between using cost-effective isomalt and avoiding drum adhesion.
Solution Approach 2:
The patent modifies parameters of the coating process such as temperature, humidity, or coating composition to alter the adhesive properties of isomalt during the coating process. By changing these parameters, the coating maintains its beneficial properties (cost, color) while reducing unwanted stickiness to the drum surface.
2Manufacturing precision
If isomalt coating is applied, then coating quality with good color and crunchy texture is achieved, but cleaning time and process inefficiency increase due to drum adhesion
Solution Approach 1:
By introducing a release agent or modified coating formulation as an intermediary, the patent enables high-quality isomalt coating to be applied without direct adhesion to the drum, thereby eliminating the need for extensive cleaning and reducing process downtime while maintaining coating quality.
Solution Approach 2:
The patent replaces the mechanical cleaning process with a chemical or formulation-based solution (release agent or modified coating) that prevents adhesion in the first place, substituting a time-consuming mechanical cleaning operation with a preventive chemical approach.
3Device complexity
If conventional saccharide solution is used for coating, then coating process is simple and economical, but coating stickiness and waste levels are high
Solution Approach 1:
The patent modifies the parameters of the conventional saccharide solution by adjusting composition, concentration, or adding functional additives that reduce stickiness. This maintains the simplicity of the coating process while significantly reducing waste through improved coating behavior and reduced drum adhesion.
Solution Approach 2:
The patent transforms the simple saccharide solution into a composite coating material by incorporating additional functional components (such as release agents, surfactants, or modified polymers) that maintain process simplicity while reducing stickiness and waste through the synergistic effects of the composite formulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method results in a less sticky coating process with low recycle levels, reduced cleaning time, and a hard isomalt coating with good color and crunchy texture, improving the overall efficiency and quality of the coating process.
Implementation Method 1
incorporating a surfactant with an HLB value greater than 10 and a coating binder like gum arabic, along with proper heating to enhance wettability and surface tension reduction
Implementation Method 2
at least one vented portion 24 of said inner drum wall 16, said vented portion 24 including a plurality of openings that allow fluid to flow into and out of said drum cavity
Implementation Method 3
conventional formation of a hard panned coating onto chewing gum is known. Such processes involve charging chewing gum cores into a rotary pan. Then an appropriate amount of a saccharide solution is added while rotating the rotary pan, to uniformly apply the saccharide solution over the surface of the chewing gum cores
Implementation Method 4
Moisture is evaporated from the coating to form a crystalline saccharide layer over the surface of the chewing gum core
