Solution Overview

Problem

Current fruit pasting processes face challenges in producing high-quality pastes while minimizing environmental impact, including the need for brine debittering, excessive water consumption, and inefficient waste management, particularly for olive pastes, and the degradation of fruit quality due to handling and storage conditions.

Innovation Solution

A movable laboratory equipped with a hydraulic direct cold press system housed in a metal container, allowing for on-site pulping and pasteurization at low temperatures, eliminating the need for brine debittering, and enabling direct disposal of waste and rinsing water back to the fields, with integrated machinery for efficient processing and waste management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional screw press or blade cutting methods are used for pulping, then the pulping process can be completed, but the quality of the paste deteriorates due to oxidation and mechanical damage

Engineering Contradiction:
Improvepaste qualityVSAvoidoxidation and mechanical damage
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies hydraulic pressure (up to 1000 bar) to compress the fruit pulp through a porous press, replacing traditional screw presses and blade cutters. This hydraulic method extracts oil and juice without mechanical shearing or excessive aeration, thereby preventing oxidation and mechanical damage while maintaining paste quality.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Manufacturing precision

If brine debittering is used for olive pastes, then the bitterness is reduced, but the processing time increases dramatically and water consumption increases

Engineering Contradiction:
Improvepaste quality (bitterness reduction)VSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent extracts the problematic compound (oleuropein) directly from the olive pulp through hydraulic pressing and filtration, eliminating the need for prolonged brine immersion. The hydraulic press separates the bitter compounds from the oil and juice in a single rapid operation, achieving debittering without the time-consuming brine treatment process.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If thermal pasteurization is used, then the paste is sterilized, but the natural and chemical characteristics of the fruit are degraded

Engineering Contradiction:
Improvepaste sterilizationVSAvoidnatural and chemical characteristics
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent changes the pasteurization parameter from high temperature to high pressure (up to 1000 bar). This high-pressure treatment achieves sterilization and extends shelf life while maintaining the natural color, flavor, and chemical composition of the fruit, avoiding the degradation caused by thermal processing.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If fruits are stored for extended periods before processing, then logistics are facilitated, but the quality of the fruits deteriorates

Engineering Contradiction:
ImprovelogisticsVSAvoidfruit quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent implements preliminary cold storage and controlled atmosphere handling before processing to preserve fruit quality. The system includes refrigerated storage compartments and rapid processing capabilities that minimize the time fruits spend in storage, ensuring they are processed at peak quality while still facilitating logistical operations.

Inventive Principle:
Principle #10Preliminary action

5Productivity

If a fixed industrial processing plant is used, then large-scale production is achieved, but the ability to process fruits at the source is lost

Engineering Contradiction:
Improveproduction scaleVSAvoidon-site processing capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent divides the industrial processing plant into modular, mobile units that can be transported to fruit orchards. The system includes containerized hydraulic pressing equipment, storage tanks, and processing units that can be deployed at the source, enabling both large-scale production and on-site processing flexibility.

Inventive Principle:
Principle #1Segmentation
