Steam Equipment in Javan Sugar Mills

I am indebted to Ray Gardiner who made the original notes in 1999 based on his six week visit. Rob van Dort and Manfred Schoeler added further short notes but significantly more data were added from my 2002/3 trips. The last major changes date from 26th September 2003 and now include many mills not previously covered plus details of much of the smaller equipment. There have been minor changes following my April, July and August 2004 visits, the latter noting extra engines at Candi, Jatibarang, Sumberharjo and Wonolangan and some scrapping at Sindanglaut. Further minor changes were made in late July 2005. I have noted some Tangye numbers from the ISSES trip in 2006, there was allegedly more data but it never came my way. I was not in Java in 2007, but a few changes I noted on my 2008 visits were then included. The latest changes (8th August 2010) reflect casualties and just a few movements from the 2010 trip (updated 7th August 2010). Please understand that I did not make comprehensive notes for this trip and much has been done from memory. The small pump record in particular will no longer be very accurate.

As part of my steamy Java Tour blog, I included pictures of every mill visited. You may want use the mill names below (final update 2nd August 2010) - note there are extra (older, from 2002) pages for Gondang and Olean. 

Use these links to view pictures of the equipment:

A guide to the pumps in Java's sugar mills 

Originally there were 190 sugar mills on Java, by 1931 there were 177 operating, but by 1939 only 84 mills were operating with 68 temporarily closed. In 1999 there were about 50 still in use.

When I first added this page, the sugar industry faced many problems, with the state of the economy large stockpiles of unsold sugar were left over from 1998, meaning that many mills had a very short season in 1999, leaving cane uncut in the fields. Over the last few years, there has been competition from cheap imported sugar and the government owned mills are subsidised, while the few private mills were in serious trouble. There are plans to relocate the sugar mills from the crowded island of Java to other islands, building new more efficient mills, but there is no capital available and with low world sugar prices it is a non-starter. With falling production, many mills experienced a shortage of bagasse to fire the mill boilers and steam locos in 1999, oil and even wood has had to be used instead/as well. Since then, the 2000/1/2/3 seasons seemed to have been surprisingly good, helped initially by the further devaluation in the exchange rate of the Rupiah but the long term prospects remain poor.

(I have arranged the mills in the same way as I have done for the steam locomotive reports. The comments in italics are my additions. The map shows only those with steam locomotives, in the list below I have described the locations of the other mills on the island.) There are links to sets of images for some of the mills included. Obviously, further additions and corrections would be very welcome. 

Rob van Dort comments: "There are two kinds of cane crushers. The usual three roller mills, called "mills" or the two roller crusher, called "crusher". In Java sometimes a crusher was installed preceding the first mill. The crusher could be driven by a separate engine or driven in combination with the first mill by the same engine. Some factories only had four mills, some older ones only three. The most ideal situation for the mill engineer is a separate engine for each mill, so the speed of each unit can be adjusted without the preceding mill choking the next one. But, some mills like Sumberharjo and Purwodadi, two mill units are driven by one engine (dual drive or tandem engines), this means very careful calculation and adjustment (opening between the rollers) of the output of the preceding mill. Below is a plan of the Sumberharjo mill (as erected) showing a crusher + engine and an engine driving the 1+2 mill and another driving the 3+4 mill. The crusher (engine) at Sumberharjo has been replaced by cane knives (shredders/unigrators) as became more and more the practice in later years. Purwodadi had an impressive mill tandem consisting of a crusher  (now out of use RD) + engine, 1 mill+ engine (Werkspoor), 2+3 mill plus engine and 4+5 mill plus engine.

The manufacturers:

I would very much appreciate some help here with their full names, locations etc... Agents such as Rombouts are noted in the main list, but a lot of equipment bears unnoted agents plates. Chris Hodrien has provide some brief notes on some UK manufacturers, I would like to expand on this...

Note the following terms (Nira = juice)

Ampasse - bagasse, the cane after it has been milled. When dry used as boiler/steam locomotive fuel
Blotong - mud from filtration after clarification
Klare - the liquid from the washings in the second purging of the solid sugars which is usually passed back to the same vacuum pan. 
Kultrog - the set of crystalisers in which the sugar is churned, often using a lineshaft driven by a steam engine 
Massecuite - mixture of sugar and molasses before separation by centrifugals
Nira mentah - raw juice after milling
Nira encer – juice after clarification
Nira jernih - filtrate from nira kotor
Nira kotor - literally dirty juice, after carbonatation/sulphitation, then clarification, before filtration
Nira kental - juice after initial evaporation 
Leburan - remelt sugar, the low grade sugar which is to be recycled to extract higher grade sugar
Stroop – the liquid from the first purging of the production sugars which is usually passed to the next lower quality vacuum pan. 
Tetes - molasses - sticky liquid residue after removal of sugar crystals by centrifugation

All machines should be assumed to be single cylindered and horizontal engines/pumps unless stated otherwise. Most have flywheels of some kind but these are not noted, the main exceptions being the simplex/duplex pumps.

NB for the milling/crusher engines, I have noted whether they are right handed (RH) or left handed (LH) where known. RH indicates that standing next to the flywheel, the steam cylinder/valves etc will be on your right. By convention the drive to the mill/crusher is placed on the same side as the valves, which mean that engines in the same sugar mill will sometimes face in opposite directions, either by design or because they have come second hand from another mill. (I have modified this definition on 21st January 2007 as, not the first time, I misunderstood what I was advised by the experts! Sorry.) By convention I believe engines run forward when the top of the flywheel moves away from the engine. This will be the setting for a non-reversing engine (only mill and crusher engines are reversible). For a belt engine where the belt runs away from the engine, this means that the slack will be at the top and maintain contact with the flywheel longer. Ideally, most mill engines will run forward too normally and the gearing between them and the mills will normally achieve this by using the appropriate number of gear wheels. Of course, with engines being moved between mills sometimes this is not possible and some engines are run in reverse, these are indicated (R) in the list.

29. Jombang Baru  

Rob van Dort comments: "I was at Jombang in 1955, assisting starting up, after the mill has been closed for many years. Passing the mill in 1989 I noticed a new boiler house. The mill was 100% steam driven in 1955, so it may be possible that inside some "damage" has occurred. Inside the mill was an unique "vacuum-machine" designed by Werkspoor . A combination of condenser, air pump, cold water pump and hot water pump in one (vertical) engine. I hope it is still there and you'll be amazed seeing this engine work, with a barking exhaust inside the building. (To which I can add that this machine is no longer present but there is one at Sumberharjo. RD)

37. Jatiroto

This large mill was modernised some time ago

38. Semboro

The mill was modernised some time ago, one half now using electric motors, the other half using steam turbines .The mill crushers were supplied by Gebr. Stork & Co, in 1922 and were probably powered by the almost standard single cylinder engines. Rob van Dort adds "newly built in 1927, with two identical sisters (Gunungsari and Bedadoeng). First campaigns 1928/29. Only Semboro survived. All three were all electric factories. Now that you report TWO mill trains it may well be, that one set was taken from Gunungsari and re-erected here, turbine powered." To which I would comment that this is one of the mills which was heavily modernised in the 1970s (RD).

46. Pakis Baru (Mill did not operate in 2000 and is reported likely to re-open in 2008.)

This is a privately owned mill and was probably the best maintained mill on Java. It was modernised some time ago and now uses steam turbines. A single cylinder engine is preserved near the front gate, a Hallesche vacuum pump inside the mill. The mill has not worked for several years and there are ongoing negotiations to transfer it to South Sumatra. More recently (November 2006) it is reported it will not move but re-open in situ.

47. Rejoagung  (Private Mill)

Considering this is one of the biggest mills in Java and installed electrically powered milling machinery nearly 80 years ago, it retains a remarkable amount of steam powered machinery. There are 2 mill trains, the second (stand-by) has steam power, the Sangerhausen mill engines are from Madukismo. The original electric motors have vanished to be replaced by turbines.

The following mill engines were taken out of use in 2009.

Staff stated that there is no steam powered machinery during a 2003 visit, a situation which we confirmed with a quick tour of the plant.

49. Krebet Baru (Private Mill)

There are two mills in the same compound, the first contains some stationary steam engines and the second is 100% modern.

The following were in use until the end of the 2003 season and then replaced by modern machinery.

52. Madukismo (A private mill near Yogyakarta dating from the 1950s)

Rob van Dort adds: "first campaign 1958. Built by Sangerhausen, steam mill engines. Have seen them being run in."

The mill was modernised ca 1976 and all steam powered equipment removed. Some of the mill engines, however, survive at Rejoagung (another was at Candi until 2003).

53. Candi (A private mill south of Sidoharjo, south of Surabaya, which uses mainly stationary steam engines)  

These mill engines were taken out of action by 2006, by then the Sangerhausen had migrated to Rejoagung and the working Haniel and Lueg to Watutulis..... The others were dumped in the mill yard. Correspondence by email in mid-2010 suggested that no steam power remains in use here, but there have been no known recent visits.

Chris Hodrien chodrien@blueyonder.co.uk has sent notes on some of the UK manufacturers:

Belliss & Morcom were previously G.E. Belliss, also in Birmingham. Their main products (and also those of W. Sisson) were fast open-crank launch engines and then enclosed high-speed force-lubricated stationary engines of standardised design mainly for driving generators, of which they built the last (about No. 11,500!) as recently as 1976 for India. They are still in business making motor-driven reciprocating air and gas compressors, which look very similar to their steam engine design (...so care is required when identifying on-site!).

Manlove, Alliott can also be found without the Fryer. I think Rouen was just a sales agency for France/French Colonies.

Ruston Proctor built portables and traction engines as well as stationary engines. They are a fore-runner of Ruston & Hornsby, who were already building stationary steam engines c. 1900 before their better-known horizontal slow speed open-crank oil engines - a small duplex used to be on show in the old Birmingham Science Museum.

Thomas Piggott engines are very rare. To my knowledge only one survives in UK - the workable preserved 1852 beam engine (+ Cornish boiler) at Combe Mill, Oxfordshire.

Worthington Simpson were the UK offshoot and licensee of the Henry Worthington Co. of New York. Newark was their main Works although earlier they had a works in East London. They were originally James Simpson & Co. before the Worthington buy-in and were/are best known for Waterworks/sewage equipment (and complete projects) and water pumps of all kinds. Both companies are still very much in business making motor-driven centrifugal water pumps. The famous patent horizontal duplex non-rotative direct acting boiler feed pump, Worthington's (USA) first product continued to be produced in huge numbers (probably the largest number of any steam design) right into the 1980s in both UK and USA and I believe they still supply spares.
