Expanded feed belt drying machine and airflow path arrangement method

Abstract

The invention discloses an expanded feed belt drying machine. The expanded feed belt drying machine comprises a closed box body, material drying areas, air ducts, material conveying belts arranged in the material drying areas and air baffles. The expanded feed belt drying machine is reasonable in structural arrangement, proper air pressure, air volume, drying temperature and the like are provided for material drying through the manners of regulating and controlling of opening and closing of ventilation holes in the air ducts and the air baffles and mutual cooperation of fans, heat exchangers and the like, a reasonable drying environment can be provided for materials in different drying stages, and therefore material drying uniformity is guaranteed, the drying efficiency and the drying quality are effectively improved, and meanwhile due to the fact that equipment compositions are simple, overall drying energy consumption of equipment is reduced. The invention further provides an airflow path arrangement method used for expanded feed drying, reasonable airflow arrangement and trends are set, dry hot air is effectively sent to each unit temperature zone, the problems of airflow turbulence and non-uniform heating are solved, the material drying efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and relates to feed drying equipment, in particular to an extruded feed belt dryer and an air flow path arrangement method. Background technique [0002] At present, the demand for extruded feed in the aquatic industry is increasing day by day, and the drying of extruded feed has become a problem that has to be considered. [0003] There are some unreasonable phenomena in the airflow arrangement of the commonly used belt dryers on the market, such as: wrong partitions, unreasonable wind-shielding devices, unreasonable dehumidification, supplementary air, etc., resulting in high energy consumption during the drying process of materials. Low efficiency, uneven drying and other problems, the specific performance is as follows: [0004] (1) Wrong partition, which does not conform to the drying characteristics of the material, will lead to unreasonable distribution of temperature and ...
