PC80 Pressure cooker

The PC80 Pressure cooker is designed to cook mussels and many other products which require a high temperature.

The product to be steamed goes into a stainless steel basket. This basket is placed on the carriage's carrying arms. On this carriage the lid of the kettle is also attached. After the rolling closure and locking of the lid, the automatic cooking cycle is started. After closing the kettle, the steam pressure is increased to the desired pressure with a maximum pressure of 4 bar. After the steam cycle, the duration of which is adjustable, the pressure is released and the lid can be opened. The basket with the product then comes out. The cooking fluid is collected in the blow off tube and can be drained if desired to be used for further purposes.

The images below show stepwise the operation of a PC80 Pressure Cooker suitable for use in separate areas. With this machine, filling and emptying of the basket does not take place in the same place but is separated from each other. For this purpose a second carriage is added and the basket is handed in the kettle from one carriage to another.

  1. The basket is filled with shellfish. The kettle will now be closed.
  2. The product is cooked. The basket is disconnected from the supply carriage and coupled to the output carriage.
  3. The kettle opens on the other side. The hinged bottom of the basket is still held close.
  4. The bottom of the basket is opened. The cooked product can now be discarded.

The empty basket is now returned to the other side via the kettle and can be refilled.
