Primary design concept of mini compression test machine for food texture analyzer

Abstract

The sensory analysis method is commonly used for the quality control process. However, this method may provide a biased result since it counts as a subjective measurement. Therefore, engineers came up with the idea of implementing a mechanical testing tool, called a texture analyzer, to measure the properties of the food itself. This study aims to develop a preliminary design of a texture analyzer that can function as a mini-compression test machine that is lightweight, portable, low cost, but still performs the texture analyzer's essential function. Design synthesis is done by reviewing the existing texture analyzers. As a result, the proposed device uses ball screws with a stepper motor as the control machine and load cell to measure the load applied. Furthermore, the dimension of this mini compression is D245 x W200 x H537.5 mm with a 250 mm effective sliding distance, and the maximum load is 10 kg. The design is smaller and lighter than the commercial product; thus, it can be considered portable. Design mainly constructed using SS304 and aluminum to provide a robust design and minimize compliance error. However, some parts were 3D printed due to the complexity in the manufacturing process. The estimated torque that the motor should produce is 1.2 N.m. This machine is expected to be useful for educational purpose as a demonstration tool. © 2023 Author(s).
