FoodSeal FoodSaver

A food preservation system engineered to work during WW1 made for a Grade 10 History project consisting of:

A hand-driven, one-way valve pump that can create a vacuum seal to preserve food in a bag.
A food dehydrator designed to be made of metal and absorb sunlight to heat and evaporate water from food. The fan at the back contributes to this process and is powered by a lead-acid battery which can be recharged using a hand-crank.
A cooler that uses an ice block to keep the dehydrated food preserved for longer.

This model was created using TinkerCAD.
