Alternative Automatic Bottling Machine for Alcoholic Beverages

A liquid bottling machine was created specifically for a small manufacturing facility whose main product is bottled Pox (a traditional Mexican alcoholic beverage). The goal of this research project was to create a low-cost automatic filling system based on the principles of an overflow filling machine but with very basic dispensing nozzles to discharge the liquid into the bottles. To establish an alternative dosing approach, an experimental investigation was done. An electrical sensor with two aluminium electrodes was created to dose the liquid volume by monitoring the free surface that rises inside the bottles. The automatic bottling machine is made up of four modules that work together to provide a constant supply of six 750 mL bottles per minute, as well as liquid dosing and delivery of full bottles for later capping and labelling. An Arduino UNO programable board was used to control the entire control system and perform the machine’s automatic functions. The machine’s movements are controlled by stepper motors. The level sensors are included in the particular dispensing nozzles, which remain stationary, while the bottles are elevated and the aluminium electrodes are inserted into the neck. Unlike overflow filling machines, the nozzles do not need to press a seal on the mouth of the bottles. The study resulted in a versatile, light, and fast machine with a reliable control system that can dose amounts ranging from 250 to 4000 ml, not only for alcoholic beverages, but for any liquid with a viscosity and electrical conductivity equivalent to water, with a maximum mistake of 15 ml.
