Abstract

General Background: Bread dough mixing equipment is an essential component in food production processes and is required to support efficient and practical operations in small-scale and home industries. Specific Background: Many bread producers still rely on manual mixing methods, creating a need for machine-based solutions capable of processing dough with appropriate capacity and structural reliability. Knowledge Gap: Limited information is available regarding the conceptual design and structural simulation of a bread dough mixer specifically developed for a 3 kg dough capacity using a systematic design approach. Aims: This study aimed to develop a bread dough mixer design with a 3 kg dough capacity and evaluate the structural performance of its frame through static loading simulation. Results: Using the morphological chart method, two design concepts were generated and Concept B was selected for further development. The designed system employed a 0.5 HP AC motor and a bowl capacity of 14.7 liters. Static simulations under loads of 170 N, 200 N, and 370 N showed that the highest load produced a maximum von Mises stress of 5.97 MPa, maximum displacement of 0.02459 mm, maximum strain of 1.97 × 10⁻⁵, and a minimum safety factor of 41.9. Novelty: The study presents a structured combination of morphological concept selection, mechanical component planning, and numerical structural assessment for a 3 kg bread dough mixer design. Implications: The findings indicate that the proposed design fulfills structural safety requirements and provides a feasible reference for future realization of bread dough mixing equipment for home industry applications.Highlights: Concept B was selected through systematic concept evaluation and proceeded to detailed development. The planned machine utilized a 0.5 HP AC motor and a 14.7-liter mixing container. Structural assessment under 370 N loading produced a minimum safety factor of 41.9, indicating secure frame conditions.

Abstract

General Background: Dough mixing is a crucial stage in bread production because it determines mixture uniformity and processing efficiency. Specific Background: Small-scale bakery production requires compact mixing equipment that is affordable, practical, and capable of handling moderate dough loads. Knowledge Gap: Existing studies discuss food-mixing machines, but limited attention has been given to the design of a compact bread dough mixer specifically intended for a 3 kg dough capacity. Aims: This study aims to design a bread dough mixer with a dough capacity of 3 kg by determining the appropriate frame configuration, transmission system, shaft dimensions, and mixing mechanism. Results: The design process produced a functional mixer configuration consisting of a structural frame, drive system, rotating shaft, and mixing blade arrangement sized to support a 3 kg dough load. Component calculations were used to determine the feasibility of the selected dimensions and operating mechanism. Novelty: The study presents an integrated design configuration focused on small-scale bread processing with a specific 3 kg operational target. Implications: The proposed design provides a practical engineering reference for the development of compact dough mixing equipment for household and micro-enterprise bakery applications. Keywords: Bread Dough Mixer, Machine Design, Mixing Capacity, Small-Scale Bakery, Mechanical Design Key Findings Highlights The machine configuration was developed for compact bakery operation. Component calculations supported stable rotational mixing performance. The design accommodated a three-kilogram dough load.
