CSTRI HOT AIR DRYING SYSTEM

Batch type Electric Hot air Drier

  • Hot air dryer is used to kill & dry the pupae and remove the moisture content  from the cocoons.
  • Cocoons will be protected from fungal attack by removal of cocoon moisture fully.
  • Fully hot air dried cocoons may be stored for a longer duration.
  • Improves significantly the quality of raw silk reeled.

MULTIEND MULBERRY RAW SILK REELING PACKAGE

                                                     Multiend Unit                                                            Multiend Machine    

  

 Re-Reeling Machine

  • Multiend Reeling package is  an improvement over cottage basin and  CSB has provided assistance for establishment of number of units by the beneficiaries during CDP IX & X plans & the scheme is continued in XI plan also.
  • This machine facilitates production of bigger lots of superior quality raw silk ensuring better productivity and higher returns for reelers.

CSTRI Improved Cottage Basin

The Traditionally dupion silk yarn is produced using double & inferior quality cocoons by engaging child labour for turning the traditional charkas under unhygienic working environment.

Improved Cottage Basin Machine

  • The reeling devices running in most of the silk clusters are primitive and outdated which results in poor quality raw silk production under unhygienic conditions.
  • Improved cottage basin reeling package has helped to produce better quality silk and also improving working environment

MOTORIZATION OF CHARKHA REELING MACHINE

Motorised Charkha

  • Charka reeling device is a crude contrivance for producing silk with minimum mechanization and practically no gadgets for quality control
  • Generally child labour is entrusted for turning charka manually
  • Motorization of charkha helps in eradication of child labour
  • Improves working conditions with better productivity

CSTRI AUTOMATIC DUPION SILK REELING MACHINE

 

Dupion Reeling Machine

  • Traditionally dupion silk yarn is produced using double & inferior quality cocoons by engaging child labour for turning the traditional charkas under unhygienic working environment
  • Automatic Dupion Silk Reeling machine has been developed to produce international grade Dupion silk
  • Technology discourages use of child labour, provides better working condition and enhances better returns

REELING TECHNOLOGY PACKAGE FOR COCOONS REARED UNDER UNFAVOURABLE CONDITIONS

  • Reeling technology package using multiend reeling machinery for the cocoons produced under unfavourable season has been developed by which considerable improvement in terms of reelability, productivity and quality characteristics of raw silk can be acheived by adopting this technology.

PROCESS NORMS FOR SILK REELING ON COTTAGE BASIN AND MULTIEND REELING

  • Process norms for silk reeling on cottage basin and multiend reeling have been developed which would help in improving the efficiency, thereby productivity, raw silk recovery and quality of silk in the reeling sector

GUIDELINES TO MULTIEND REELERS FOR PRODUCTION OF RAW SILK YARN TO CATER TO THE REQUIREMENTS OF  ZARI MANUFACTURERS

  • A set of guidelines are now available to Multiend reelers which can guide them to produce raw silk yarn quality similar to the domestic basin in order to cater to the requirements of  zari manufacturers

EIGHT END IMPROVED COTTAGE BASIN REELING MACHINE

8 ends Improved Cottage Basin Reeling Machine

  • Low cost 8 ends / basin 6 basin improved cottage basin reeling machine has been developed for mulberry silk reeling, which would reduce the capital investment of the reelers considerably
  • The reeling machine can work with medium / superior quality cocoons from which gradable raw silk (2A) can be produced
  • It has been provided with jetteboute system, individual reel stop motion and adjustable speed pulley
  • It can produce up to 1.0 kg of raw silk / basin / shift of 8 hours
