Abstract
Dehydration, a well-known and efficient technique for food preservation, can be provided by an equipment known as dehydrator (or dryer), that produces a hot airflow, to which the food is exposed until its water molecules are extracted. However, working temperatures must not exceed certain limits, under risk of denaturation of the exposed food molecules, which implies the need for temperature control. Thus, the objective of this work was to build a dehydration chamber with temperature control that meets the performance requirements for this type of apparatus. In this manner, the project began in the conception and design of the equipment; then the physical parts were machined and fixed to one another, forming the structure, which could then receive the electrical and electronic components; Finally, the system was analyzed from the thermal point of view, i.e. its dynamics were described in mathematical terms, which, through the use of computer simulation tools, was used for the design of the temperature control system. The results from the perspective of the performance of the temperature controller were formidable, so were the dehydration results, which were equivalent or superior to those of the commercially available equipment of this type. In short, the dehydrator chamber was built successfully, maintaining fidelity to the scope from all angles - aesthetic and functional.
