Solution Overview

Problem

Conventional devices for preparing food purees require prolonged steaming, leading to nutrient depletion, especially for sensitive nutrients like vitamin C and B-vitamins, as they are heat-sensitive, resulting in a smoother texture but at the cost of nutrient loss.

Innovation Solution

An apparatus with a controller that adjusts steam parameters and liquid supply based on user-input texture requirements, allowing for shorter cooking times and precise moisture control to achieve a smooth texture without excessive steaming, thereby retaining nutrients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If prolonged steaming is used to achieve smoother puree texture, then the smoothness of the puree is improved, but nutrient depletion increases

Engineering Contradiction:
Improvepuree smoothnessVSAvoidnutrient depletion
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent changes the steaming parameters by introducing controlled liquid supply during steaming process. This allows achieving the desired puree smoothness with shorter steaming time by supplementing moisture through liquid supply, thereby preventing nutrient depletion while maintaining texture quality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies preliminary action by supplying liquid to the food ingredients before or during the steaming process. This pre-supplied liquid reduces the required steaming duration to achieve target moisture content and smoothness, thus preserving heat-sensitive nutrients

Inventive Principle:
Principle #10Preliminary action

2Loss of substance

If shorter steaming time is used to retain nutrients, then nutrient retention is improved, but puree smoothness deteriorates

Engineering Contradiction:
Improvenutrient retentionVSAvoidpuree smoothness
Core Design Contradiction:
Loss of substanceVSManufacturing precision

Solution Approach 1:

The patent introduces liquid supply as an intermediary element that mediates between steaming time and puree smoothness. The supplied liquid acts as a bridge, providing necessary moisture for smooth texture without requiring prolonged heat exposure, thus enabling short steaming time while maintaining smoothness

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the moisture parameter by supplying additional liquid during steaming. This parameter change allows achieving target smoothness with reduced thermal processing time, thereby retaining nutrients while maintaining texture quality

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided is an apparatus (100) for preparing a food puree comprising a chamber (102) for containing food ingredients and a steam supply (104) for supplying steam to the chamber for steaming the food ingredients. A liquid supply (106) supplies a liquid to the chamber and an agitator (108) purees the steamed food ingredients in the presence of the liquid to obtain the food puree. A user interface (110) permits user selection of a texture of the food puree. A controller determines a steam parameter and a liquid amount to be supplied by the liquid supply according to the user selection. The controller further controls the steam supply and the liquid supply according to the determined steam parameter and liquid amount. Further provided is a method for preparing the food puree.
