Seal & Serve

Seal & Serve is a cocktail maker that allows the users to fully customise the recipe of the drinks and also has the ability to fill and seal plastic pouches, Caprisun style. This feature allows for plenty of drinks to be prepared beforehand and take it away to picnics, barbecues, beach days and more. This project was made through the Electromechanical System Design course at CMU with 4 other talented engineers. I worked on the CAD design of the system, testing of the pumps and the wiring.

Problem

Ever organise an outdoor gathering like a picnic or a barbeque, and realize you need to many cans or bottles of drinks? The existing products such as those you see in supermarkets don’t offer much customizability in terms of ingredient proportions, flavour varieties, and drink strength. Seal & Serve allows the user to make and package any drink they want from the comfort of their home

The design

Seal & Serve features 6 removable beverage containers for easy cleaning and refilling of drinks. The liquid in these containers are pumped using peristaltic pumps that are controlled by a raspberry pi. The pumps direct the liquid to the center of the machine where either a cup or a plastic pouch is located. Under the cup a weight sensor is located which stops the liquid flow when enough of it has been dispensed.

Results

The prototype of Seal & Serve has shown that it can prepare and fully seal plastic pouches. Its user interface allows users to enter any number of recipes with any proportion of the ingredients, achieving its goal of customisability. On average the product dispenses 2.3ml of liquid per second and takes 25 seconds to seal. On average it takes 150 seconds from start to finish to prepare a drink. While the product satisfies the minimum requirements that was set out at the beginning of the project there are still improvements that can be made. Such as the main material of the body should be changed from wood to a more waterproof material like Acrylic. The pumps should be improved to reduce the time it takes to prepare a drink.
