Tunnel curing barn adopting humiture subdivision control of alternate wind direction

Abstract

Disclosed is a tunnel curing barn adopting humiture subdivision control of alternate wind direction, and the tunnel curing barn is formed by a plurality of work cells, which are penetrated through and connected by a track. Each work cell comprises a baking cell, an air-mixing layer and a hot air cell. Each work cell is provided with one hot air cell or the plurality of work cells share at least one hot air cell. The air-mixing layer is located between the baking cell and the hot air cell. Material trolleys which pass through the baking cells respectively move a distance of one baking cell every time, and the material trolleys are used for being filled with materials to be baked. A circulating fan is installed in the air-mixing layer to produce an ascending airflow or a descending airflow. A heating or heat exchanging device is disposed in the hot air cell. The whole tunnel curing barn is separated into a plurality of independent work cells by separating plates which are provided at the front end and the rear end of the material trolleys in the baking cells, and each work cell forms an independent hot air self-circulating system. The material trolleys on the track move forward at intervals and are capable of moving at fixed time and fixed quantity and staying in different work cells for drying according to temperature and humidity required by materials at different times.

Description

technical field [0001] The invention relates to a tunnel-type curing barn, in particular to a tunnel-type curing barn adopting segmental control of temperature and humidity in alternate wind directions. Background technique [0002] Tunnel-type hot air drying is a drying method that has been used for many years. High-temperature hot air enters from one end of the tunnel and exits from the other end of the tunnel. Material enters one end and exits the other, lining up in the tunnel. When the high-temperature hot air at the inlet enters the tunnel and contacts the material, it evaporates the moisture of the material, the temperature of the hot air drops, and the humidity increases, so the baking environment (temperature, humidity) of the downwind material is very different from that of the upwind material, and the material is in the whole baking process. , the baking environment from entering to exiting is changing at any time, the parameters that can be controlled are only t...

Problems solved by technology

When the high-temperature hot air at the inlet enters the tunnel and contacts the material, it evaporates the moisture of the material, the temperature of the hot air drops, and the humidity increases, so the baking environment (temperature, humidity) of the downwind material is very different from that of the upwind material, and the material is in the whole baking process. , the baking environment from entering to exiting is changing at any time, the parameters that can be controlled are only the temperature of the incoming air, the wind speed, it is impossible to achieve the best combination of baking temperature curve and humidity curve, dehydration speed, let alone take care of the tunnel Changes in temperature and humidity due to changes in material loading
