A Low-Cost Egg Incubator to Provide Zambian Churches with Income and Food Security

Partnering with Brethren in Christ (BIC) Church in Zambia, the Egg Incubator Team is seeking to help provide a source of income for the growing churches in Choma, Zambia. They will accomplish this by designing and building a high-quality, low-cost egg incubator fabricated from local parts and cheap internationally available parts for The Nahumba Mission, in Choma, Zambia. The team’s design will provide the means for the Mission to hatch and sell chickens to provide both food security and a sustainable supplemental income. With the specifications to maintain temperature, humidity and constant ventilation, the team selected heating and humidity concepts for their incubator series. The team completed both mechanical and electrical designs for the setter and hatcher. In preparation for testing the incubator design with fertilized eggs, the team has also produced an incubation and hatching plan and achieved IACUC approval. Currently, the team is in the prototyping phase, while simultaneously monitoring the temperature and humidity in an existing incubator setter design. Once the team finishes their hatcher prototype and verifies that the temperature and humidity specifications are met, they will be ready to test designs using fertilized chicken eggs.https://mosaic.messiah.edu/engr2021/1020/thumbnail.jp

High Quality, Low Cost Egg Incubator for BIC Church in Choma, Zambia

The Egg Incubator team is partnering with the Brethren in Christ Church located in Choma, Zambia to design a high-quality, low-cost chicken egg incubator to supply the pastors and church members with a means of food and income. The design will need to take into account the accessibility and cost of the tools and materials. The current prototype features separate heating and humidity systems, a control system to maintain a set temperature and humidity, and tilting egg racks. The heating system consists of two stovetop coils to produce heat and a fan to transfer it to the air. The humidifier utilizes an atomizer in a pan of water to create a mist that mixes with the hot air to create humidity. The control system uses a proportional integral derivative controller (PID) to keep the temperature at 37 ± 1 °C and the humidity at 60–70%. The egg racks are tilted by a motor that runs every 6 hours to prevent the embryos from sticking to the shell. With a fully functioning prototype, the team has begun to incubate 60 real fertilized eggs. During the 21-day incubation process, a final prototype iteration is being designed and will be built on-site in Zambia in May 2022.
