Solution Overview

Problem

Existing methods for producing pasta filata cheese face challenges in achieving desired performance characteristics and nutritional qualities, including difficulty in obtaining specific ingredient concentrations and activating latent functional properties, with significant cheese component loss during processing, particularly during the heating and stretching process.

Innovation Solution

The use of electromagnetic energy, specifically microwave and radio frequency energy, to heat and manipulate cheese curd, creating a uniform heating profile and reducing water loss, thereby improving solids retention and product yield.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional hot water heating is used for pasta filata cheese production, then the cheese curd can be heated to target temperature, but significant cheese solids are lost to the cooker water

Engineering Contradiction:
Improvecheese curd heating temperatureVSAvoidcheese solids loss
Core Design Contradiction:
TemperatureVSLoss of substance

Solution Approach 1:

The patent replaces the traditional mechanical hot water heating system with an electromagnetic energy system (microwave or radio frequency). This substitution eliminates the need for water as a heating medium, thereby preventing cheese solids from being lost to the cooker water while still achieving the required heating effect on the cheese curd.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of the heating method from thermal conduction through water to direct electromagnetic energy absorption by the cheese curd. This parameter change allows heating to occur without the cheese curd being in contact with water, thus eliminating solids loss while maintaining temperature control.

Inventive Principle:
Principle #35Parameter changes

2Temperature

If traditional hot water heating is used for pasta filata cheese production, then the cheese curd can be heated and stretched, but significant resources are dedicated for the retention of solids and disposal of liquids

Engineering Contradiction:
Improvecheese curd processing temperatureVSAvoidresource consumption for solids retention and liquid disposal
Core Design Contradiction:
TemperatureVSLoss of energy

Solution Approach 1:

By replacing the hot water heating system with electromagnetic energy heating, the patent eliminates the generation of large volumes of liquid waste that require disposal and the energy-intensive processes needed to retain solids from the water. This substitution removes the entire water management infrastructure requirement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the water medium from the heating process, thereby eliminating all the problems associated with water management including solids retention systems and liquid disposal requirements. The heating function is achieved without water entirely.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of substance

If electromagnetic energy is used for heating cheese curd, then solids retention is improved and water loss is reduced, but uniform heating profile must be achieved

Engineering Contradiction:
Improvecheese solids retentionVSAvoidheating profile uniformity
Core Design Contradiction:
Loss of substanceVSManufacturing precision

Solution Approach 1:

The patent adjusts electromagnetic energy parameters such as frequency (microwave or radio frequency ranges), power levels, and exposure duration to achieve uniform heating. By carefully controlling these parameters, the system ensures that all portions of the cheese curd receive appropriate energy input without creating hot spots or underheated regions.

Inventive Principle:
Principle #35Parameter changes
