Dark-green vegetable powder beverage dispersibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powder beverages containing dark-green vegetables often lack excellent dispersibility, particularly when the vegetable content is high, making them difficult for consumers to mix with liquids.
Innovation Solution
The use of dry powder with a specific median diameter or granulating dark-green vegetables through fluidized-bed granulation to create a powder beverage that disperses quickly and stably in water, with methods such as crushing and drying treatments to achieve optimal particle size and binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the content of dark-green vegetable in powder beverage is increased, then the nutrient intake is improved, but the dispersibility of the powder beverage deteriorates
Solution Approach 1:
The patent applies parameter changes by controlling the particle size of dark-green vegetable powder through specific crushing and screening processes. By adjusting the particle size parameter (using screens with specific mesh sizes), the powder achieves optimal dispersibility while maintaining high vegetable content. This physical parameter modification allows the powder to disperse easily in liquid without requiring reduced vegetable content.
2Ease of operation
If the particle size of dark-green vegetable powder is reduced, then the dispersibility is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the particle size reduction process into distinct stages: initial crushing, intermediate screening, and final fine crushing. This multi-stage approach segments the manufacturing process to achieve fine particle size (improving dispersibility) while using simple, conventional equipment at each stage. The sequential segmentation allows progressive size reduction without requiring complex single-stage systems.
Solution Approach 2:
The patent applies preliminary action by performing coarse crushing and intermediate screening before the final fine crushing stage. This preliminary processing prepares the material by removing large particles and reducing bulk volume, making the final fine crushing more efficient and less energy-intensive. The preliminary actions simplify the overall manufacturing process by breaking down the complex size reduction task into manageable steps.

AI summary
A powder beverage that includes at least one type of dark-green vegetable, wherein a dispersion time measured by the following procedure is 10 min or less: put 100 mL water in a container having a circular truncated cone shape, a bottom having an inner diameter of 55 mm, a top part having an inner diameter of 75 mm, and a height of 100 mm; inject the powder beverage from above 50 mm of the water surface at a rate of 1 g/sec; and measure the time (dispersion time) from when injection of the powder beverage is terminated to when the powder beverage floating on the liquid surface is submerged in the water.
