Solution Overview

Problem

Conventional belt frying systems for food products are inefficient due to energy loss through steam, difficulty in maintaining a contained environment, and issues with debris accumulation, leading to poor oil quality and potential fire hazards.

Innovation Solution

A novel fryer design featuring a base, hood, and conveyor system with baffle members to create a substantially air-tight frying chamber, including steam recapture and exhaust ports to reduce energy consumption and prevent air infiltration, along with a conveyor system using side links and slidable members to minimize debris accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional belt frying systems are used, then food products can be fried, but a large amount of energy is lost to the atmosphere in the form of steam

Engineering Contradiction:
Improveenergy loss through steamVSAvoidsystem structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent employs a hood structure with baffle members that create a contained environment over the frying conveyor, effectively trapping steam and heat within the frying chamber. This enclosure acts as a flexible shell that prevents energy loss to the atmosphere while maintaining the frying process

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The steam recapture port positioned between the baffle members captures steam that would otherwise be lost, allowing for energy recovery and reuse in the frying process, directly addressing the energy loss problem

Inventive Principle:
Principle #34Discarding and recovering

2Object-affected harmful factors

If conventional belt frying systems are used, then frying can be performed, but structures collect crumbs or other debris, thereby degrading oil quality and creating potential fire hazards

Engineering Contradiction:
Improvedebris accumulationVSAvoidcleaning difficulty
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The conveyor system is designed with slidable members that ride in recessed channels, effectively separating the conveyor components from the base structure. This extraction of conveyor elements from direct contact with the base eliminates surfaces where crumbs and debris can accumulate, addressing the harmful factor of debris collection

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hood structure with baffle members creates a contained environment that prevents debris from scattering throughout the kitchen, confining it to specific areas that are easier to manage and clean

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If conventional belt frying systems are used, then food products can be fried, but the systems are not well-contained and energy is quickly lost to the atmosphere

Engineering Contradiction:
Improvecontainment efficiencyVSAvoidhood and baffle structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hood with baffle members forms an enclosed shell structure over the frying conveyor, creating a well-contained frying chamber that prevents energy loss to the atmosphere while maintaining operational reliability

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The hood structure is divided into sections with baffle members positioned at specific locations, including a steam recapture port between the baffles. This segmentation allows for targeted control of steam flow and heat retention, improving containment efficiency

Inventive Principle:
Principle #1Segmentation

AI summary

A fryer can include a base having a reservoir for receiving oil for frying a food product and a hood coupled to the base. The fryer can have an inlet at an upstream section and an outlet at a downstream section. At least one conveyor can move food product from the inlet to the outlet. A first baffle member and second baffle member can be positioned over the conveyor to define a frying chamber therebetween. The first and second baffle members can restrict air from flowing into the frying chamber from outside of the frying chamber.
