Solution Overview
Problem
Existing deep frying devices face issues with pyrolysis of food particles and high wear due to localized high temperatures and difficult repairs, leading to reduced operational efficiency and increased downtime.
Innovation Solution
A deep frying device with a detachable heating module that includes a pipe section protruding into the container, allowing for easy replacement and cleaning, and an enlarged heat exchange surface to minimize pyrolysis and extend device lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the container is heated at the bottom with a burner, then the fat can be heated effectively, but the temperature of the bottom of the container becomes too high causing pyrolysis of food particles
Solution Approach 1:
The heating system transitions from bottom-only heating to multi-dimensional heating by adding side heating surfaces. The container now receives heat from the bottom and from sides through channels, distributing the thermal load across multiple surfaces rather than concentrating it at the bottom, thereby preventing pyrolysis while maintaining effective fat heating.
Solution Approach 2:
Combustion gases serve as an intermediary heat transfer medium. Instead of direct flame contact with the container bottom, the burner heats combustion gases that then flow through channels along the container sides, indirectly transferring heat to the fat and container walls without creating localized overheating zones that cause pyrolysis.
2Ease of repair
If the deep frying device requires repair due to cracking, then maintenance can be performed, but the operating time is reduced and turnover is lost
Solution Approach 1:
The container is divided into a stationary main body and a separable heating section. The heating section can be detached as a complete module, allowing repairs or replacements to be performed on just this segment without affecting the rest of the container. This segmentation enables quick maintenance that minimizes operational downtime and preserves productivity.
3Object-affected harmful factors
If channels are added to increase heat exchanging surface, then pyrolysis is reduced, but the device complexity increases
Solution Approach 1:
The heating section merges multiple functions into a single integrated module: it contains the burner, houses the combustion gas channels, provides heat exchange surfaces, and can be detached as one unit. This consolidation achieves the pyrolysis-prevention benefit of complex channel structures while managing overall device complexity through functional integration and modular design.

AI summary
Method and a deep frying device for deep frying a food product in a deep frying device, wherein the deep frying device comprises a container for fat. For reducing the chances of damaging the deep frying device by the deep frying and increasing the availability, use is made of a deep frying device comprising a pipe section for hot flue gas which protrudes into the lumen of the container but is not connected to an opposite wall. The pipe section comprises - a plurality of supply pipes for the relatively hot flue gas, and - at least one outlet pipe for the relatively cold flue gas coming from the plurality of supply pipes.
