Automatic Molasses Pump Control Set

Abstract

The purposes of this research are: to create and identify the efficiency of Automatic Molasses Pump Control Set. As problem found in the fermentation processes of Liquor production of Theparunothai Co.,LTD., manually ON-OFF Molasses Pump and cause tolerances 8–10 % in each step of fermentation. So we defined the efficiency of Automatic Molasses Pump Control Set as follows: the operation of the set must cause tolerances less than 5%. From our literary review, so we decided to designed and created Automatic Molasses Pump Control Set controlled by Arduino Nano, programed to control the set to operate with flow meter feeding back controlling ON and OFF molasses pump in both steps of fermentation process that differently require quantity of molasses.  In the first step require 28,000 liters of molasses, while the second require 14,000 liters. The results of the experiments found that: step 1 of fermentation using Automatic Molasses Pump Control Set has tolerances of 0.357%, while in step 2 found tolerances of 0.714%, theses mean tolerances decrease from manual method down to 92.86%. So we can conclude that Automatic Molasses Pump Control Set has efficiency as defined. Automatic Molasses Pump Control Set can help saving cost, if calculate from 5 baht per liter, the cost of molasses. In each loss of manual pump control can loss up to 2,000 liters, which can calculate into 10,000 baht in each time of fermentation step. In one year possibly have fermentation of 900 tanks (twice a tank). That means Automatic Molasses Pump Control Set can save production cost up to 18,000,000 baht per year and also can save time and energy of fermentation process. And may extend the result widely in the affiliates companies.
