Steamy Java Sugar Mill Tour 2010, The German Connection
This series of pages from July and August 2010 records our travels from China to Malaysia and on to Java, Indonesia where we were hosting the 'Steamy Java Tour 2010'. Click here for the main Winds of Change index page.
Rejosari was a 'Halle' mill, it was featured in their advertising material and several of its engines are still here including the four in the main mill line. In recent years, it has gained a reputation for being difficult to penetrate owing to the less than welcoming attitude of its chief engineer. As a result we scheduled our visit after the loco tour had checked in and, more importantly, after he would have finished his day's work. Of course, we paid the admission fee but we based ourselves in the chemistry laboratory to avoid the engineers' office. In the event, we were treated with some suspicion by the Satpam (security) but they were readily satisfied by our paperwork and we were left free to roam as we wanted as had been the case in every other mill so far.
Despite sharing the same manufacturer only the first and second mill engines are similar, with slide valves with twin eccentrics. The third engine is a drop valve engine and the fourth engine has slide valves with triple eccentrics and a complex governor. The blue cylinder appears to be part of a pressure balancing system for the mill rollers. Space is at a premium in this part of the mill and photography is not easy.
Elsewhere, just about everything is better positioned. This is a (Halle) air compressor and nearby is another pump whose maker is not known, it seems to be a juice pump.
I was pleased to see that the belt engine for the lime plant was still in use, not far from it is a classic vertical mud pump.
Rejosari is indeed well blessed with steam powered pumps. On the left is a Halle water injection pump and on the right an unidentified vertical boiler feedwater pump.
There are two vacuum pumps from Stork and Halle although I haven't seen the latter actually working for some time.
The kultrog is run by a pair of oppositely handed Tangyes at either end:
Not for the first time here, the main centrifugals and their immaculate Stork belt engine were not working when we arrived but got going later. Those for the second part of the purging are classic Watson, Laidlaw products.
The production sugar is carried away by the usual 'grasshopper', dried and passed into the traditional Jacob's ladder for temporary storage. After which it is bagged and weighed and carried away on a 'ski lift'. A guaranteed appearance on this report was an irresistible temptation for one worker.
The loco tour had less success in the Madiun area, but here Salak was teamed specially to strut up and down before them. After they had left for Cepu, I sneaked out and caught up with my old friend. I guess there will be more on this loco on John's blog - http://www.linesiding.co.uk.
We'll be apart for the next 3 days and will join up again in Probolinggo.
