Abstract
Cooking machine and method include a mould with first and second similarly shaped end walls and a generally surrounding, continuous side wall, the three walls together defining an internal moulding volume, with the three walls being reciprocally movable relative to one another. Heating elements are provided in at least one wall or in thermal contact therewith, and a control mechanism controls at least relative movement of the walls so that at the end of a predetermined cooking cycle the end walls and the sidewall are relatively separated to retract both end walls from the moulding volume simultaneously.
Claims9
A method of cooking comprising:
- introducing a cookable mixture into a moulding volume having opposed ends;
- confining the volume of the moulding volume;
- introducing heat for a predetermined cooking cycle;
- allowing expansion of the moulding volume for a short predetermined period;
- and
- opening the moulding volume adjacent each end simultaneously and extracting the cooked article.
A pneumatic device for moving an element using either a large or a small pneumatic force comprising a large cylinder defining a large air volume having a large piston therein and a small cylinder defining a small air volume having a small piston therein, the small and large pistons being coupled together and arranged for coupling to the element, each of the cylinders having an air input on one side of the respective piston and an air output on the other side of the respective piston, and the large cylinder further being provided with a selectively closable air passage extending between the two sides of the large piston, such that, when a large pneumatic force is required, the air passage is closed so that air pressure on the one side of the large piston provides the force, whereas when a small pneumatic force is required, the air passage is open so that air pressure in the large cylinder is equalized on either side of the large piston such that the air pressure on the one side of the small piston provides the force.
