Solution Overview

Problem

Existing methods for processing liquid food with particles require separate processing lines for water and food concentrate and particles, leading to increased costs and particle maceration during heat treatment, which affects the quality of the final product.

Innovation Solution

A system comprising a blender, a heat treatment unit, and a control unit that integrates the blending of water and food concentrate with the introduction of particles directly into the heat treatment unit, allowing for optimized heat treatment and minimal particle maceration by selecting the introduction location based on the heat requirements of the particles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two separate processing lines are used for water/concentrate and particles, then heat treatment effectiveness is improved, but device complexity and energy cost increase

Engineering Contradiction:
Improveheat treatment effectivenessVSAvoidprocessing line complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the water/concentrate processing line and particle processing line into a single integrated processing line. The blender combines water, concentrate, and particles in one sequence, and the heat treatment unit processes the complete mixture in one continuous flow, eliminating the need for separate processing lines while maintaining heat treatment effectiveness through optimized residence time and temperature control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heat treatment unit is designed to handle both the liquid food matrix and suspended particles simultaneously in a single processing stream. The system performs multiple functions - heating, pasteurization, and particle treatment - within one unified processing line, reducing overall system complexity while achieving the required heat treatment effectiveness for both components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If two separate processing lines are used for water/concentrate and particles, then heat treatment effectiveness is improved, but energy cost increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

By combining both processing streams into one continuous flow through the heat treatment unit, the system eliminates the need for duplicate heating systems, pumps, and control mechanisms. This single integrated line processes both liquid food and particles simultaneously, significantly reducing total energy consumption compared to operating two separate heat treatment systems.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If particles are heat treated separately, then heat treatment effectiveness is improved, but particle maceration increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The blender is designed to optimize particle distribution and suspension in the liquid food matrix before the mixture enters the heat treatment unit. This preliminary conditioning ensures uniform heat distribution and appropriate residence time during heating, achieving effective pasteurization while minimizing excessive particle maceration through controlled blending parameters and flow conditions.

Inventive Principle:
