Solution Overview

Problem

Existing methods for preparing fried protein dishes face challenges such as contamination risks from spoiled or raw batter, spoilage of protein, and the need for freezing to preserve, which complicates large-scale commercial production and handling.

Innovation Solution

A method involving coating uncooked protein with a high-gluten batter, sealing it in pouches, and cooking below the batter-hardening temperature, followed by chilling and optional spoilage inhibitor application, allowing for later breading and flash frying at serving temperature without the need for freezing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If liquid batter is applied to protein pieces for coating before frying, then the protein pieces achieve a crispy crust, but the batter may spoil when kept at room temperature or in chilled state, creating hygiene problems

Engineering Contradiction:
Improvebatter coating qualityVSAvoidbatter spoilage risk
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The batter is applied to the protein pieces in advance during manufacturing, and the coated pieces are then flash-fried to set the coating. This preliminary coating action eliminates the need to store liquid batter at the restaurant, preventing spoilage while maintaining coating quality

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the physical state and application method of the coating from liquid batter to a dry mix that is applied as a dusting or light coating. This parameter change allows the coating to be stable at room temperature and eliminates spoilage issues while still achieving the desired crispy crust when flash-fried

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If protein pieces are coated with batter and kept at room temperature for prolonged period, then preparation time is reduced, but the protein and batter may spoil, creating contamination risks

Engineering Contradiction:
Improvepreparation timeVSAvoidcontamination risk
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The protein pieces are pre-coated with the dry mix during manufacturing and then flash-fried to set the coating. This preliminary preparation eliminates the need for extended room temperature storage, reducing both preparation time at the restaurant and contamination risks

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses flash-frying to quickly cook the pre-coated protein pieces, rushing through the cooking process to minimize the time the food spends in the temperature danger zone where bacterial growth occurs, thereby reducing contamination risks

Inventive Principle:
Principle #21Skipping (Rushing through)

3Stability of the object's composition

If protein pieces are refrigerated in chilled but not frozen state for extended period, then freshness is maintained, but the protein may spoil, creating hygiene problems

Engineering Contradiction:
ImprovefreshnessVSAvoidspoilage risk
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent changes the coating from liquid batter to a dry mix formulation that is stable at room temperature and in chilled storage. This parameter change allows extended storage without freezing while maintaining both freshness and preventing spoilage, eliminating the hygiene problems associated with prolonged chilled storage of liquid batter

Inventive Principle:
Principle #35Parameter changes

4Productivity

If cooking is completed while food product is in the pouch, then processing efficiency is improved, but it requires varying ingredients for different food products, increasing complexity

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidingredient variation requirement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses a universal dry mix coating formulation that can be applied to various types of protein pieces (chicken, fish, other animal proteins). This universal coating system maintains processing efficiency while eliminating the need to vary ingredients for different food products, reducing complexity

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

AI summary

A system for cooking a food product, in particular pieces of protein, includes an optional first station that receives uncooked pieces and applies an effective amount of a spoilage inhibitor to the pieces to delay growth of toxigenic bacteria; a batter applicator that receives the pieces of uncooked protein, optionally with the inhibitor from the first station, and applies a high-gluten batter to the outer surfaces of the pieces of uncooked protein; a packaging machine that receives the pieces of uncooked protein coated with the batter from the batter applicator and seals the pieces of protein in plastic pouches; and a heating unit that receives the sealed plastic pouches containing the uncooked protein coated with the batter from the packaging machine and cooks the battered protein pieces in the plastic pouches at a time and temperature below which the batter hardens.
