the flow chart may look somewhat like as in Fig. 3.1. Fig. 3.1 Flow chart for vegetable dehydration For preparation of a flow chart, first of all we have to know the sequence of operations. Or in other words, we can know the proper sequence of operations and better understand the process, if we have a flow chart of the process.

Lautering – The grits are separated from the water. The sugar-water saturate is drained off from grains. The sticky liquid is called wort. Boiling – The wort is boiled, and then hops and adjuncts are added into the wort. Boiling time lasts for 60-120 min. Fermentation – Boiled, strained and cooled wort is transferred to the fermentation vessel and yeast is added.

How aluminium is produced

The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be used on high quality bauxite with fairly low content of admixtures, especially silicon.

Bayer process. In the Bayer process, bauxite is mixed with a side stream of returning spent caustic liquor and ground down to a size appropriate for extraction. The slurry is then preheated and held in storage tanks to facilitate silica removal (desilication). The main spent liquor stream is also preheated and mixed with the slurry stream.
