In recent decades, the interest and demand for maca (Lepidium meyenii) have grown worldwide, establishing the tuber as one of Peru's flagship products, so adding value to it without losing its nutritional properties is a viable option to further increase its production and sale. Therefore, the most efficient process to consider is freeze-drying, which allows for preserving most of the organoleptic and nutritional properties of the food over time. The objective of this work is to design a compact and easy-to-use machine, which allows generating an added value to maca through freeze-drying. For this purpose, the VDI 2221 methodology was used, where a list of requirements was considered according to the structure of the freeze-dryer, a black box, and a white box, which led to making the morphological matrix from which the optimal 3D prototype was obtained. The result of this design showed t...

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...
