High-temperature hot water circulation-free fan drying room

Abstract

The invention provides a high-temperature hot water circulation-free fan drying room, and relates to the technical field of drying rooms. The high-temperature hot water circulation-free fan drying room comprises a heat preservation room, a material rack is fixedly installed inside the heat preservation room, a hot water coil pipe is fixedly installed inside the material rack, a heat recoverer is fixedly installed on one side of the outer surface of the heat preservation room, a material tray is fixedly installed inside the material rack and located above the hot water coil pipe, the material tray is internally provided with a material, and one side of the outer surface of the heat preservation room is rotationally connected with a feeding and discharging door through a hinge. According tothe high-temperature hot water circulation-free fan drying room, by applying two heat transfer mode of heat conduction and convection, a circulation fan is omitted in the drying process, heat is permeated into the interior of the material from a material surface layer through the heat conduction, a gas flow is formed on the surface of the material in the dehumidifying process of a dehumidifying fan, and the heat transferring is conducted between the gas flow and the material. The drying mode is adopted, namely the problem that the energy consumption of the circulation fan is large is solved, and the consistency of the drying degree of the material is ensured as well.

Description

technical field [0001] The invention relates to the technical field of drying rooms, in particular to a drying room with high-temperature hot water without a circulating fan. Background technique [0002] There are three ways of heat exchange: conduction, convection, and heat radiation. The existing fruit and vegetable drying and grain drying systems all use the "convective heat transfer" method when drying materials. On the outer surface of the materials, an airflow with a certain flow rate and temperature is created to evaporate the moisture in the materials. [0003] In order to form a certain flow rate of air in the drying room, fans must be used. In actual use, the power consumption of the circulating fan that makes the air flow accounts for half of the power consumption of the entire drying system, or even more. The drying method obviously consumes a lot of energy, and this drying method only evaporates the moisture on the surface of the material, and it is difficult ...

Problems solved by technology

[0003] In order to form a certain flow rate of air in the drying room, fans must be used. In actual use, the power consumption of the circulating fan that makes the air flow accounts for half of the power consumption of the entire drying system, or even more. The drying method obviously consumes a lot of energy, and this drying method only evaporates the moisture on the surface of the material, and it is difficult for the hot air to penetrate into the inside of the material. The speed and temperature are difficult to be consistent, and the dryness of the material is uneven, which affects the quality of the material
