Abstract
For the production of parboiled rice or a similar starch-containing product, the rice, after conveniently being moisted in a preheating installation 1, is brought to boiling temperature and, having reached this, is kept at this boiling temperature in a heat-retaining vessel 9 until the cooking process is finished. Thereupon, the rice is dried in a drying installation 12 and cooled, if necessary.
Claims16
An apparatus for hydro-thermically treating a starch containing product, comprising
- boiling means for boiling said starch containing product, said boiling means including boiling vessel means for holding said product,
- heat supply means for supplying heat to said boiling vessel means, and being operative to bring the product up to boiling temperature,
- heat retaining vessel means separate from said boiling means and operatively connected to said boiling means for receiving said product from said boiling means and for maintaining said product at boiling temperature during a predetermined period, said heat retaining vessel means including tubing through which a heat transfer medium can flow for conducting heat to said product while in the heat retaining vessel means, said heat retaining vessel means having an outlet region,
- nozzles disposed in said boiling means for injecting steam into said product, and
- drying means connected to the outlet region of said heat retaining vessel means for drying the product after boiling by said boiling means, said outlet region of said heat retaining vessel means being located adjacent said drying means.

An apparatus for hydrothermally treating a starch containing product, comprising
- boiling vessel means for boiling said starch containing product, said product being contained within said boiling vessel means during boiling of said product,
- heat retaining vessel means operatively connected to said boiling vessel means for receiving said product in a boiled state from said boiling vessel means and for maintaining the product at a boiling temperature during a predetermined period,
- drying means connecting with an end region of said heat retaining vessel means for drying the product upon passage of the product through said heat retaining vessel means,
- heating means for said heat retaining vessel means,
- wherein said heat retaining vessel means forms a passageway for allowing continuous passage of said product in a predetermined direction of flow, and said heating means comprises
- a plurality of tubings extending within said heat retaining vessel means in a direction across said direction of flow, and
- source means for a heat carrier medium connected to said tubings, said tubings being adapted to permit said heat carrier medium to flow through said tubings and transfer heat to said product.
