Abstract

This project aims to improve existing dough proofer in term of its size, capacity, cost saving and working principle and also to apply the integration of cooling rack with the dough proofer. This is because the current dough proofer is big and bulky, and also already equipped with the fixed rack which can only proof a little amount of dough at a time. Through this project, a prototype will be fabricated and tested to determine the performance of the dough proofer machine that affected by two factors that affecting proofing process; temperature and humidity. To ensure the project are achieved in accordance with the scope and objectives, the problem statement has been identified and previous scientific studies have been used as a reference. After conducting a short interview with the baker and reviewing the customer’s requirements, the decision to implement a conceptual design of dough proofer machine has been made. Then, the general shape and dimension of the design have been chosen and transient thermal analysis has been done in order to get the predicted results before running the actual prototype testing. Having identified the components and material needed, the prototype been fabricated and tested to obtain the results and compared to the theoretical data from the literature review and also calculated the overall cost for producing the prototype. Based on the prototype testing, the results are 37.1 ˚C for the temperature and 49% for the humidity which the prototype does not reaches its optimum temperature and humidity for the proofing process. It is due to the lack of temperature and humidity sources and also the errors when fabricate the prototype. The prototype also is cheaper compared the existing dough proofer machine in the market. To improve this dough proofer machine, the heat source and humidity of the dough proofer machine should be converted to a source with a better performance level. Additionally, the selection of appropriate materials should be considered to replace the material used in the prototype and reduce the cost of producing a better dough proofer machine.
