Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preserving and processing plant-based milk, particularly oat milk, face challenges such as rapid spoilage, nutritional degradation due to pasteurization, and high energy consumption, leading to suboptimal product quality and sustainability issues.
Innovation Solution
A method involving the production of a solid oat milk product through blending a dry oat milk base with oil and compressing it under pressure, which is then reconstituted with water to create a functional liquid beverage, reducing energy input and packaging waste while maintaining nutritional content and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traditional dehydration and compression techniques are used to preserve plant-based milk, then longevity and storage stability are improved, but energy consumption increases and nutritional quality deteriorates
Solution Approach 1:
The patent changes the physical state parameter of the plant-based milk from liquid to solid form through direct compression of fresh material. This parameter change enables long-term storage at room temperature without energy-intensive dehydration processes, as the compressed solid form naturally prevents microbial growth and spoilage.
Solution Approach 2:
The patent replaces thermal dehydration processes with mechanical compression. Instead of using heat to remove water and preserve the milk, the invention uses direct mechanical compression to densify the fresh plant-based milk into a stable solid form, eliminating the need for energy-intensive drying ovens and freeze-drying equipment.
2Stability of the object's composition
If traditional dehydration and compression techniques are used to preserve plant-based milk, then storage stability is improved, but nutritional quality and freshness deteriorate
Solution Approach 1:
The patent performs preliminary compression of fresh plant-based milk before any degradation can occur. By compressing the material in its fresh state and sealing it in packaging, the process locks in nutritional quality and flavor profiles before oxidation, spoilage, or nutrient degradation can take place during traditional dehydration processes.
Solution Approach 2:
The patent replaces thermal processing with mechanical compression to maintain nutritional integrity. The mechanical compression process occurs at ambient temperatures, preventing heat-sensitive nutrients, vitamins, and phytochemicals from degrading, while still achieving long-term storage stability through the physical densification and exclusion of oxygen.
3Reliability
If liquid form plant-based milk is used, then product quality and functionality are improved, but packaging waste and transportation costs increase
Solution Approach 1:
The patent changes the physical state from liquid to solid through compression, which dramatically reduces volume by a factor of 5-10 times. This enables the same amount of product to be packaged in much smaller containers, reducing packaging material usage and waste, while also lowering transportation costs due to reduced volume and weight.
Solution Approach 2:
The patent segments the product into compressed solid units that can be individually packaged and stored. Consumers can compress only the amount needed and store the rest in its fresh, uncompressed state, reducing overall packaging waste compared to traditional liquid cartons that require full-container preservation.
4Duration of action of stationary object
If pasteurization is used to preserve plant-based milk, then shelf life is improved, but nutritional content and flavor deteriorate
Solution Approach 1:
The patent replaces thermal pasteurization with mechanical compression and aeration. The compression process, combined with controlled aeration during or after compression, creates a solid structure that is naturally resistant to microbial spoilage without requiring heat treatment, thereby preserving heat-sensitive nutrients and authentic plant-based flavors.
Solution Approach 2:
The patent changes the physical state parameter to solid form through compression, which inherently extends shelf life without thermal processing. The solid compressed structure prevents microbial growth and oxidation that would otherwise require pasteurization, maintaining both shelf life and nutritional quality simultaneously.

AI summary
A solid oat milk alternative product is formed by mixing a dry base that includes about 60% to about 80% by weight of whole oat flour; about 0% to about 5% by weight of an emulsifier, about 0.1% to about 5% by weight of a stabilizer, about 0% to about 1% by weight of a foaming enhancer. The dry base is mixed with about 15% to about 30% by weight of an oil to form a dough. The dough is compressed or extruded to form the solid oat milk product.
