Multipurpose modular dryer having compulsory air circulation for drying all agricultural and forestry fruits, including tobacco, according to the invention, consists of three different modules (A), (B) and (C), combination of which produce small, middle and large dryers depending on the desired capacity. Modules are arranged in rows of which each row has at least module (A) and two modules (C) which represents dryer of smaller capacity, and by adding one or more modules (B) capacity is increased, while extending of capacity is achieved by addition of new rows and so that the main row stays and along it only three sides are added, while one side from the previous dryer stays joint. In the main - zero module (A) a fan (1) is put, driven by electromotor (2) and device for its turning for 180° for the revers air flow, and the spiral heaters (44) and the executive device (18) for operation of central unit for automatic control of drying process of materials, while modules (B) and (C) have no device and practically serve for maintenance of required temperature and air humidity. On module (C) there are only door (46) and rectifier (45). |
