Fogging System For Ginning

 

 

 

 

The moisture in kapas plays a vital role in processing at ginning. The seed cotton that is too moist does not separate into locks and tends to form wads which are trapped between knife edge and roller of the roller gin and chocks up the ginning; on the other hand, the seed cotton that is too dry generates static electricity and causes frequent stoppages by accumulating on the surface of the synthetic roller of the roller gin. It is also a known fact that, moisture level in the kapas does not remain same through out the season and therefore causes variation even in the same variety of cotton after ginning. The kapas from the first picking exhibits adequate moisture in the cotton fibres, which gets reduced in second and third picking. Therefore it is very much essential to keep optimum level of moisture in the kapas during ginning by positively controlling the humidity in the ginning area, to get maximum ginning out-turn with consistency in fibre quality of ginned cotton.

 

Hence, to maintain the level of moisture contents, fogging system is required. The conventional method of fogging (i.e. use of fans) is not suitable for ginning due to following disadvantages.

  • Uniform spreading of moisture cannot be achieved. Hence, at some place, fibres get excessively wet.
  • It uses large quantity of water
  • Power consumption is high

Hence to solve above problems with conventional method & to maintain the most desired humidity level in ginning, an advanced fogging system of high pressure pump with socialized fog nozzles is used. This advanced fogging system run by high pressure pump offers the following advantages vis-à-vis conventional method.

  • It generates fogging and not spraying or sprinkling which means no water dropping and hence do not damage the cotton.
  • It uses specialized nozzles, which allow even fogging and ensure desired level of humidification.
  • There is no wastage of scarce water.
  • The minimum usage of water helps in maintaining the staple length of cotton and as the short fibers settles down the quality of cotton improves.
  • It is an environment friendly method as flying fluff is considerably reduced simultaneously restricting wastage of cotton.
  • Quick evaporation of sprayed water helps in maintaining cooling level of the ginning and pressing rooms.
  • It is user friendly and easy installation.
  • Power consumption is too low which ultimately results in saving in energy bill.
  • Maintenance cost of the system is also low
