Description
Technical field
The present invention relates to grow cotton processing device and a method of operating thereof, particularly about a kind of unginned cotton Minton dryer and method of operating thereof.
Background technology
Unginned cotton ripe on cotton plant is unicellular, has been covered with cotton fiber above, and length is between 25～33mm; The cotton fiber of natural generation is a kind of wood fibre, a plurality of hydrophilic hydroxyls (OH) of ining succession on its macromolecular structure chain, and it can absorb the hydrogen ion (H+) in Hot wet air heating just, is combined into hydrone (H
2o), this is the immanent cause of the easy moisture absorption of cotton fiber.In cotton harvesting season, relative humidity in atmosphere is higher, causes unginned cotton regain higher, sometimes more than 16%, high like this regain can not directly enter cotton gin processing, generally will guarantee that the unginned cotton regain that enters cotton gin is in 8% left and right in processing technology.
When the relative humidity of research atmosphere, often mention the concept of dry air.Under atmosphere pressure state, dry air always has certain relative humidity, because the vaporization degree of water is different, relative humidity is also different.The temperature that liquid water becomes hydrone through vaporization is 100 ℃; But along with the reduction of air pressure, the vapourizing temperature of water is also reducing.Such as: when air pressure is under 0.1 atmosphere pressure state, the vapourizing temperature of water just only has 15 ℃.And subatmospheric air condition can be called vacuum, in the situation that vacuum pressure is constant, while improving system temperature, in the material that is dried, will has more aqueous water and be vaporized, thereby rate of drying is accelerated; As keep temperature-resistant in vacuum system, and reduce vacuum, also have more aqueous water vaporization and accelerate rate of drying.And still do not have at present a covering device that vacuum drying is dried to processing procedure for unginned cotton.
