Development of a Filter-Based Fruit Preservation System via Refrigerating System

The development of fruits is among the most important of human developments. Fruits have been in existence even before man. A great revolution began when the early hunters discovered they could plant seeds, influence growth, and maintain plant fertility. Throughout the millennia, mankind has indeed succeeded to grow fruits, but have also developed their own specialty types with distinct tastes or engineered to grow in specific places. Fruits is not only seen as a source of food but as a source of raw materials to create other products. The preservation of these fruits is highly essential. This report entails the development of a fresh fruit preservation system. It combines the use of an ethylene filter and the vapour compression refrigeration system to keep fresh fruits from losing their value. During the project, the previous contributions to the field, made by others, were considered, and applied. The device was made to hold and preserve 13 kg worth of fruit. The ethylene filter compromises of potassium permanganate which oxidizes ethylene and keeps the fruit from spoiling. The evaluation of the system was done by comparing the conditions of the fruit under different controlled conditions. The COP of the system was found to be 0.98 and the fruits were in better condition under the refrigerated ethylene absorption condition.
