Prototype

Our project is Flavorator.We show its system working under real-world conditions in India . Because India has a problem about storage of foods ,and we thought that our Flavorator can solve this problem.

According to Assocham that is Joint Chamber in India , 30 percent of the total harvest of agricultural crops in India have been discarded by lack of refrigerated storage facility . Refrigerated storage facility is insufficient in the retail market in rural areas and suburbs.In 2011,Refrigerator penetration in the cities is 43.8% , and villages is 9.4%(fig1). The penetration in rural areas is much smaller than the city group . Its cause is considered that supply of electricity are not yet ready. To solve this problem, there is a need for method of preserving food products that do not require electricity in rural and suburban markets. Our Flavorator does not require electricity. So, we considered that it is used in situations such as the India, and designed Flavorator.

Design

fig2:Design of Fravorator

This is the design of Flavorator

Container of medium is attached in above the box , fragrances is produced from there (①). Fragrance falls to bottom from top and circulate by it cause a natural convection (④).

It must to keep temperature in Flavorator for recombinants activity . A layer of vacuum suppress the change of temperature in Flavorator because it work as　a heat insulator.(②)


To prevent the　contact of recombinants and foods, the container of the medium is covered by a triple filter　(③).　Recombinants are larger than the mesh of filter, so they can't go through a triple filters , but fragrance is able to pass through because its molecules are smaller than the mesh　(fig3).

※Recombinants differs depending on the temperature in a region which use Flavarator. (For example : India , will use Escherichia coli because temperature is its active range.)
