Vertical type damp-heat and speed-controlled thin layer drying experiment stand and drying method thereof

Abstract

The present invention discloses a vertical type damp-heat and speed-controlled thin layer drying experiment stand. The experiment stand comprises: a shell body, a liner, a material warehouse and a sensor set. An air distribution opening, a moisture distribution opening, a moisture removing fan, a first warehouse sealing door and a second warehouse sealing door. Drying medium enters into the shell body from the air distribution opening and discharges from the shell body from the moisture removing fan. The receiving space of the liner is a drying medium flow path and the liner is fixed in the shell body; a material warehouse tray is arranged at the lower part of the liner corresponding to the first warehouse sealing door and a sensor warehouse is arranged at the lower part of the liner corresponding to the second warehouse sealing door. Dried grains can be placed in the receiving space of the material warehouse and the material warehouse is connected to the material warehouse tray. The sensor set consists of a temperature sensor, a humidity sensor, a wind speed sensor and a wind pressure sensor, and is arranged in the liner. The drying experiment stand can provide the optimal parameter ratios for drying experiment methods, thereby reaching the ultimate purposes of increasing drying efficiency of dryers, reducing energy consumption, and ensuring drying quality.

Description

technical field [0001] The present invention relates to thin layer drying machines. More specifically, the present invention relates to a vertical damp-heat speed-controlled thin-layer drying test bench and a drying method. Background technique [0002] Our country is a large agricultural country, the yield of grains in crops is huge, and with the improvement of people's living standards, people's requirements for food quality have also increased, but it is inevitable to encounter some problems in life: most of the agricultural products and various food Needs to be kept at low moisture levels, so its moisture content needs to be reduced before storage. At present, the traditional drying method mainly adopts hot air drying equipment, which makes the hot air pass through the grain particles under normal pressure to take away its moisture. [0003] my country's grain drying has a history of decades of development, but most of them are used in agricultural production, mainly i...

AI Technical Summary

Problems solved by technology

The amount of mechanical drying of grain in my country is increasing year by year, especially in the Northeast region. The drying time is usually from October to March of the next year. Due to the characteristics of low external temperature, high grain moisture, and poor moisture uniformity during this period, grain drying is common. There are problems such as high drying energy consumption, low quality after drying, and difficulty in controlling moisture content.
