Designing and Development of Bread Mixing Prototype for Local Community in Uttaradit Province

Abstract

This article aims to design and developed a prototype of small bread mixer machine for local community in Uttaradit province. The intention of designing and development this machine were mixed the flour and other ingredients for baking bread and guideline for using in other local community in Thailand.

          The design of the bread mixer is based on data from Ban Khlong Huai Phai community in Uttaradit and other research. Then, developed to be suitable for production capacity, that community needs. Which the bread mixer can generate torque about 1,100 watts from 2 horsepower motor, that use for power unit. The mixing tank has volume of 30 liters and can produce 10-12 kilograms per day, has 15 rpm in idle speed and 185 rpm in work mode. In efficiency study process is compare this machine and general. It was found that the yeast fermentation time could be reduced from 20 minutes to 15 minutes. Measuring the flour growth, that is measure at a diameter of 5 centimeters, expanded to 12 centimeters. In measuring the quality of bread after baking at temperature and the usual time. It was found color measurement in CIE L*a*b standard of bread were L (60.266 - 64.044), a (-2.412 - -0.174) and b (23.230 - 28.911)
