Conical Screw Cooker

Initial product and solid or liquid ingredients are filled into the conical screw cooker mainly by gravity and may be homogenised prior to the heat treatment process.

For sterilisation or heat treatment steam may be flushed into the conical cooker under pressure and high temperature to heat and sterilise the batch and/or to extract certain ingredients. This may be assisted by a heated jacket, protected against  heat loss and for safety reason by an overall insulation jacket. Condensed liquid could be drained and an initial drying process could be maintained by applying vacuum to the heated process cooker.

When the heat treatment process is finished, the product and the equipment may be cooled down to an acceptable discharge temperature by cooling the jacket or by pulling vacuum using the evaporation energy to cool the batch.

The final product is discharged via the bottom discharge valve into a bin, container or conveying system by gravity, assisted by agitation of the screw  and arm without leaving residues at a high yield.

For cleaning the equipment internals between individual batches, or before product change, fix welded spray nozzles will spray cleaning fluid to the entire inner cooker surfaces. All product exposed or contaminated parts are wetted, washed down and rinsed with cleaning liquid or water. This guaranties an efficient total cleaning of the fully contained cooker internals.
