Solution Overview

Problem

Conventional steaming processes for producing steamed noodles or instant noodles require large amounts of steam, leading to high energy consumption and inefficiencies, resulting in undercooked tastes when instant noodles are cooked, as the existing methods are complex and require precise sealing.

Innovation Solution

A steaming method where steam is supplied to noodle strings for a predetermined period in a tunnel-type steaming device, followed by continued transportation without steam supply, maintaining internal temperatures of 98 °C or more at both the entrance and exit portions, and utilizing exhaust devices to maintain steam density and temperature, with a partition member to prevent steam volatilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If steam is continuously supplied to noodle strings in a tunnel-type steaming device, then steaming efficiency is improved, but steam consumption and energy usage increase significantly

Engineering Contradiction:
Improvesteaming efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies periodic action by dividing the steaming process into distinct phases: a steam supply period where steam is actively supplied to the noodle strings, followed by a steam stop period where steam supply is halted but the steaming process continues using residual steam and heat. This periodic on-off steam supply pattern maintains steaming efficiency while significantly reducing overall steam consumption and energy usage compared to continuous steam supply.

Inventive Principle:
Principle #19Periodic action

2Loss of energy

If steam supply is reduced to decrease energy consumption, then energy efficiency is improved, but steaming quality deteriorates causing undercooked taste

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsteaming quality
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by ensuring that sufficient steam is supplied during the initial steam supply period to thoroughly penetrate and steam the noodle strings before the steam supply is stopped. This preliminary steam exposure ensures that the noodles achieve proper cooking quality, and the subsequent steam stop period allows the residual heat and steam to complete the steaming process without requiring additional energy input, thus maintaining quality while improving energy efficiency.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If conventional steaming methods are used to ensure thorough cooking, then cooking quality is maintained, but steam consumption and production cost increase

Engineering Contradiction:
Improvecooking qualityVSAvoidsteam usage
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent implements periodic action with alternating steam supply and steam stop periods. During the steam supply period, steam is actively provided to cook the noodle strings. During the steam stop period, steam supply is halted but the steaming continues utilizing residual steam and heat within the tunnel-type device. This periodic pattern reduces overall steam consumption and production costs while maintaining thorough cooking quality through the cumulative effect of both periods.

Inventive Principle:
Principle #19Periodic action

4Productivity

If steam is supplied continuously at high speed production, then production speed is maintained, but steam consumption increases

Engineering Contradiction:
Improveproduction speedVSAvoidsteam consumption
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies periodic action by implementing alternating steam supply and steam stop periods that are synchronized with the high-speed production flow. The steam supply period provides necessary moisture and heat to the rapidly moving noodle strings, while the steam stop period allows residual heat to complete the steaming process. This periodic pattern maintains production speed by ensuring continuous movement through the tunnel while significantly reducing steam consumption compared to continuous supply at the same production rate.

Inventive Principle:
Principle #19Periodic action
