Problem
Current methods for producing kebab slices are limited in scale, prone to contamination, inefficient, and result in high fat content, with electric knives having short lifespans and posing health risks due to microbial buildup and inconsistent cooking quality.
Innovation Solution
An automated process involving a meat grinder, extruder, flattener, computer-programmed knife, infrared grill, fat removal system, freezing tunnel, packaging, and metal detection for high-volume production of thin, short, and narrow kebab slices with reduced fat content, ensuring hygiene and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rotating and grilling method is used, then kebab slices can be produced with acceptable quality, but production capacity is limited to below 600-1000 kg per hour
Solution Approach 1:
The continuous kebab block is segmented into individual slices at controlled intervals, allowing each slice to be independently processed and cooked to consistent standards while maintaining high production throughput
Solution Approach 2:
The traditional manual or electric knife slicing system is replaced with a computer-programmed slicing apparatus that uses controlled mechanical movement to achieve precise, consistent slice thickness and dimensions at high speed, ensuring uniform cooking results
2Productivity
If electric knives are used for slicing, then kebab slices can be produced efficiently, but the knives have short lifespan and require frequent sharpening and replacement
Solution Approach 1:
The system uses disposable slicing elements or easily replaceable blades that can be quickly changed without requiring frequent sharpening, reducing maintenance time and ensuring consistent slicing performance throughout their short service life
Solution Approach 2:
The computer-programmed slicing system automatically adjusts and maintains optimal slicing parameters without manual intervention, compensating for blade wear through automated compensation mechanisms
3Ease of manufacture
If traditional slicing method is used, then kebab slices can be produced, but there is risk of microbial contamination from knife buildup and worker contact
Solution Approach 1:
The slicing operation is extracted from the manual process and performed by an automated computer-programmed system, removing the source of microbial contamination (workers and traditional knives) from direct contact with the food product
Solution Approach 2:
A hygienic barrier or protective covering is introduced between the slicing mechanism and the kebab meat, preventing direct contact and potential contamination while allowing the slicing function to continue
4Productivity
If manual or traditional automated slicing is used, then kebab slices can be produced, but workers are exposed to high temperatures and risk repetitive joint injuries
Solution Approach 1:
The slicing system is fully automated with computer programming that handles all slicing operations autonomously, eliminating the need for workers to manually operate near high-temperature grilling areas and perform repetitive slicing motions
Solution Approach 2:
The production process is segmented into distinct automated zones (grilling, slicing, packaging), allowing each function to be performed by specialized equipment in controlled environments, removing workers from harmful temperature zones
5Productivity
If traditional grilling process is used, then kebab slices can be cooked, but the process is not sensitive to product demand variations leading to overcooking or undercooking
Solution Approach 1:
The computer-programmed system incorporates feedback mechanisms that monitor cooking progress and slice production rate, automatically adjusting grilling parameters to maintain consistent cooking quality while matching production demand variations
Solution Approach 2:
The grilling and slicing system uses dynamic, computer-controlled parameters that can be adjusted in real-time based on production requirements, ensuring consistent cooking quality whether producing small or large batches

AI summary
Process for large-scale automated production of frozen packaged thin kebab slices comprises feeding a meat mixture into a meat grinder. The meat mixture is provided to an extruder which presses the meat mixture out through one or more openings. The extruded meat is provided to a flattening system forming thin kebab slices which can be grilled. Excessive fat can be removed from the grilled kebab slices which are then cut into shorter slices and frozen, The frozen kebab slices can be weighed and packaged, The packaged kebab slices pass a metal detector which discards packaged meat with metal objects.
