Storage Tanks
Silo tanks
Silo tanks for raw material reception belong to the storage category and have been described under "Collection and reception of raw material”. They vary in size from 25 000 to about 150 000 liters and the wetted surfaces are of stainless steel. They are often placed outdoors to save on building costs. In these cases the tanks are insulated.
Intermediate storage tanks
These tanks are used to store a product for a short time before it continues along the line. They are used for buffer storage, to level out variations in flow. After heat treatment and cooling, the product is pumped to a buffer tank, and from there to filling. If filling is interrupted, the processed product is buffered in the tank until operation can be resumed. Similarly, product from this tank can be used during a temporary processing stoppage.
