Analysis and Development of a Poultry Hatching Machine

2020-07-09 , Irfan Abd Rahim , Muhamad Hafiz Ab Aziz , Ghani H.A. , Muhamad Farizuan Rosli , Fazdly M.K. , Azlida A.

The egg-hatching machine comprises a several main factors that has been adapted and developed in this machine. The main factors are temperature, humidity, turning orientation and ventilation. The development of the machine without considering these factors will lead to failure or low percentage of hatching success. Therefore, these important factors must be included and adapted to machine. The best temperature for egg incubation is 37.8 °C or 100 °F and for relative humidity is from 55% to 65%. For egg, turning and orientation can be done from 2 to 6 times daily. The angle for turning is from 30° to 90°. The use of forced-air incubation method in this machine instead of still-air incubation had helped to regulate the air and supply oxygen to the eggs in the chamber. Besides considering all factors, other supportive factor that will help to increase the percentage of hatching success also must not be neglected. The supportive factors are location to place the machine, insulation for preventing heat loses and hygiene or cleanliness of the machine. Although these supportive factors are not the main parameter for egg incubation, these factors also need some attention as they also one the keys for hatching success.

The purpose of this study is to use water cooler and water heater to improve the convenience of the user so that they can use the water cooler and mobile water heater properly and comfortably. This study focuses on how refrigeration and water heaters use thermoelectric pads as a cooling and heating medium. Peltier works when the voltage is flowing from the power bank. The temperature difference on the surface of the processor allows the heat to occur at a fast rate. Arduino uno is used as a voltage regulator and temperature sensor to improve product performance. concept designs are designed, created and evaluated. The final prototype will include some markers that will be used as temperature readings by cooling and heating. Based on the results shown, the prototype can achieve the desired result with optimized energy consumption. When the temperature supplier produces a good temperature, the amount of water temperature will rise and the heat in the water will reach thermal equilibrium until the cold and hot temperatures reach a better minimum. Therefore, the temperatures in the cold and hot areas are more efficient in achieving thermal equilibrium in rising water.

This paper presents an analysis of the mechanism of Belt-Pulley Driven Spray Plunger Pump. Belts and pulleys are used to transfer kinetic energy from the internal combustion (IC) engine to operate the pump. Combination of pulley and belts was used to transfer motion between each other simply without the need for meshed toothed gearing. The principal remains the same that there is a driver (powered) and driven (free). The benefit from application of belts which are mostly made of synthetic fibres is that no lubrication is necessary compared to chains. The analysis is focused on power transmitted from IC engine to plunger pump (design power) considering service factor as well as determining total number of belts to be used in the system with refer to FENNER Friction Belt Range Brochure Technical Docs.
