Shandong Ruyi to grow up with Thies dyestuff weighing station

The MPS systems (Multi Product Supply) use a joint control management and data structure. A general central system ranging from the machine control to the overload systems serves to co-ordinate all the processes in the dyehouse.
First in Asia The installation has been further automated earlier this year with a fully automatic Thies MPS-Colormatic to control the complete dyestuff handling from stock to the dyeing machine.
Stock-keeping, weighing, dissolving and dispensing the dyes is integrated in an automatic cycle. Featuring 40 silos, the Colormatic incorporates twin robot operations – one to select mixing bowls and one for measuring dyestuffs before forwarding to MPS-D's.
Reduced labour Once commissioned, the new operation will significantly reduce operating costs - requiring just two operators for all 32 Eco-blocs compared with earlier 10-12 per shift.
The automatic Thies facility will also ensure reduced wastage, faster mix and preparation times of dyestuffs and importantly, confirms Li Lian Feng, “Significantly reduce operator errors.”
One MPS-D is configured to supply 10 eco-blocs – 4 x 120 kg and 6 x 50 kg, whilst the second unit also supplies 10 eco-blocs – 2 x 20 kg and 8 x 120 kg.
A third unit, a mini MPS-D, feeds the remaining 12 smaller capacity eco-blocs – 4 x 30 kg, 8 x 10 kg.
Both MPS-L's are configured so that one supplies the 200 kg, 120 kg, 100 kg and 50 kg machines, with the second feeding the smaller 10 kg and 30 kg units.
Li Lian Feng confirmed that following the installation of the MPS systems, an improvement in the quality of dyed yarns has been noticed, together with a reduction in the consumption of chemicals, since they are now served precisely and on demand.
Any worries about residues of dyestuffs or chemicals in the transfer pipes, as previously experienced by Shandong Ruyi, have been eliminated as the MPS systems automatically rinse the pipe systems clean after each transfer.
Production Up to 80% of production at the new facility is wool yarn from loose fibres, with Shandong Ruyi also producing the remaining 20% with polyester, silk, linen and viscose in a 24/7 operation.
For the future, Shandong Ruyi has plans underway to introduce cashmere dyeing which, as Yong Aiguo confirms, will require more Eco-blocs and automated MPS-D and L systems and another Colormatic automatic dyestuff weighing station.
