The arapaima, also known as paiche or pirarucu is one of the largest freshwater fish in the Amazon, in which its cultivation has been growing progressively due to consumer demand. This research presents the design of a real-time monitoring and control system of water parameters for paiche farming, which employs mechatronics concepts using the Vdl- 2206 methodology. The study controls and monitors the water's temperature, dissolved oxygen, and pH. Sensors obtain the values for each parameter, process them by a PLC, and project them on an HMI interface. The environment is programmed based on the information provided by FONDEPFS, which mentions that the water temperature for paiche cultivation must be between 26ºC to 31°C, the pH leve! between 6 and 8 UI, and dissolved oxygen with a value greater than or equal to 4 mg/L. In addition, the proposed mechatronic system aims to be a user-frien...

The production of essential oils is widely used in the world to combat various diseases. In addition, these oils are essential in the seasoning and flavoring of food and have applications in the field of cosmetology, helping to reduce environmental pollution by avoiding the use of chemical products. Peru is one of the fourteen most outstanding countries for its rich biodiversity in flora and fauna, and is also the sixth largest exporter of citrus fruits in the world. Therefore, a citrus essential oil extraction process is analyzed through the design of an industrial-scale essential oil distillation machine. This design includes the automation of the filling and emptying of the distiller to improve the results, as well as the implementation of a closed-loop control system for cooling. The objective is to facilitate operator control and monitoring of the cooling and water filling process t...

With this project has been designed an induction electric stove powered by a photovoltaic storage system, which will make it self-sustainable without generating additional costsin the billing of electricity consumption. This solution is aimed at families in rural areas who still continue to use traditional fuels (wood, gasoline, straw, etc.) for the preparation of their food, which over time generate serious problems in people's health due to the CO2 that is produced. The project involves the implementation of a system of photovoltaic cells at the top of the houses of which would have connections to a set of batteries that would serve as the source to the operation of an electrical induction kitchen inside the house. The project demonstrates the results focused on the generation of energy capable of supplying the operation of the kitchen and for this the Helioscope simulator was used to ...

Food, due to its high handling, is more prone to contamination. This damage not only occurs when it comes into contact with the customer and the seller, but it can also occur at any stage of the food production chain because the products pass from hand to hand and from place to place, so it is necessary to perform its disinfection constantly at least 3 times a day. Currently, it has been identified that at the production stage, food can be affected if contaminated freezers are used either for washing, packaging, or cooling. During the slaughter process, microbes surrounding the slaughtered animal can end up in the final meat products. If any microbes contaminate the food processing lines, they can spread and affect other foods in contact. According to the WHO (World Health Organization), it is estimated that around 600 million people worldwide fall ill from contaminated food every year a...

In this research, an innovative mechanical- electronic device has been developed for the efficient purification of carrots seeds, a critical process in agricultural production due to its impact on the quality and yield of future crops. The device uses mechanical and electronic principles to effectively separate impurities and unwanted seeds from carrots.
