FRUIT DRYING DEVICE

RATIONALE

The researchers would like to create this prototype because there might be some dried fruits that were exposed so much to flies and you are eating it and it’s not safe. So by creating this prototype, you can be sure that it’s safe to eat and it’s cheaper too.

  People, who cannot afford to buy a dehydrator

and want to make dried fruits, will be able to benefit from this prototype because unlike the dehydrator, this device won’t need electricity for it to dry fruits because it is solar powered. It makes the device affordable. It is also easier to use because all you have to do is place the sliced fruits on the Fruit Drying Device and place it in a low-humidity area and where sunlight is efficient.

STATEMENT OF THE PROBLEM Main Problem

Is fruit drying using the fruit drying device prototype more effective compared to fruit drying using the traditional fruit drying technique?

Sub-Problem:

1. Is there a significant difference in the quality of fruits dried using the fruit drying device prototype and the traditional fruit drying technique in terms of :

TasteColorTexture

2. Is there a significant difference in the time required to dry fruits using the fruit drying device prototype and the traditional fruit drying technique?

 

Methodolgy

The researchers made use of mangoes. Mangoes are the most common dried fruit in the Philippines. Two devices would be tested, the Fruit Drying Device 1 (FDD 1) and the Fruit Drying Device 2 (FDD 2), alongside the traditional fruit drying technique. The devices would be tested at least three times to determine whether the FDD 1 or FDD 2 is more effective than the traditional fruit drying technique.
