Steamer

Also called: paddy steamer, parboiling machine, paddy parboiling plant, paddy steaming machine

Step 3 of 8: Parboiling

A vessel that passes steam through the soaked paddy. The starch sets, so the grain turns harder and breaks less when it is milled.

Steamer: how it works

  1. Soaked, drained paddy is filled into a closed vessel.
  2. Steam from the boiler is let in through pipes with small holes, so it spreads through all the paddy.
  3. The heat cooks the starch inside the husk; the grain turns glassy and hard.
  4. The steam is shut off and the hot paddy is let out at the bottom, straight to the dryer.

Main types

Batch steaming tank
One load is steamed at a time, often in the same tank it was soaked in.
Continuous steamer
Paddy moves steadily through a steam zone, which gives even cooking and suits large automatic mills.
Pressure parboiling vessel
Steams under pressure for a shorter time, which makes a harder, darker parboiled rice.

Where it fits in the process

It stands between soaking and drying in the parboiling section, and takes its steam from the mill's boiler.

What to tell us

  • How much paddy you parboil in a day.
  • The kind of parboiled rice your market wants: light or dark, single or double boiled.
  • Batch or continuous.
  • The boiler you have and the steam it gives.
  • New or reconditioned.

Common questions

What is parboiling, and why is paddy parboiled?

Parboiling means soaking, steaming and drying paddy while it is still in the husk. The grain becomes harder, so fewer grains break in milling, nutrients move from the bran into the grain, and the rice keeps better. Most rice eaten in Bangladesh is parboiled.

What is the difference between a batch and a continuous steamer?

A batch steamer cooks one tankful, is emptied and is filled again; it is simple and fits smaller mills. A continuous steamer takes paddy in and lets it out all the time, which gives the same cooking to every grain and needs less labour.

What is the price of a paddy parboiling machine in Bangladesh?

We do not publish prices. The price depends on batch or continuous, how much paddy it must steam in a day and what comes with it, such as tanks, conveyors and controls. Send us the points listed above and we will quote.

  • Soaking tanks

    Large tanks where clean paddy is soaked in water, often warm water, until the grain has taken up enough to be steamed.
