Yummy Ice: automatic minuta machine
- Problem
- Clients who knew us for 3D printing and prototyping arrived with an ambitious idea: fully automating a minuta — the Salvadoran shaved ice with flavored syrups and tamarind jelly you find on every corner on a hot day. Machines existed to shave ice; none existed that did the whole process, from on-screen selection to a served minuta, with no person in between.
- Build
- We designed a prototype and three production versions — two fully autonomous and one compact semi-autonomous for events. The machine makes shaved ice on the spot from an internal purified-water reservoir, doses syrups and jelly to the customer's touchscreen selection, dispenses the spoon, protects the interior with an automatic door and takes cash payments. Everything came out of the shop: mechanical, electrical and electronic design, four degrees of freedom, up to ten dosing pumps, hardware-revision-aware firmware in C, and a Linux mini server with a React frontend, remotely reachable over WiFi or cellular for analytics, maintenance and updates. The system is patented at the Centro Nacional de Registros.
- Result
- Seven machines built and delivered: one exported to the United States, four for Salvadoran malls and two compact versions working private events. We keep maintaining the machines in operation. A street-corner treat turned into an engineered product — with its own patent.
