Abstract
The invention relates to hydraulic control for carrying out a method of producing a cracker from cereals, which are pressure-baked in a heated mold and expanded afterwards. In particular the hydraulic control system, comprising of a plurality of hydraulic cylinders, will lead to an increased expansion speed or an increased speed for opening the dies, resulting in constant high-quality food products.
Claims4
A food baking apparatus comprising:
- a hydraulic drive system comprising at least three hydraulic cylinders;
- and
- two dies at an adjustable distance (d) from each other, the two dies being configured for a food product to be baked between the two dies, the two dies being operable to be opened or closed by adjustment of the adjustable distance (d) by the hydraulic drive system,
- wherein:
- each of the at least three hydraulic cylinders comprises a double-acting piston and a position sensor;
- each of the at least three hydraulic cylinders has a respective stroke;
- and
- the at least three hydraulic cylinders cooperate with one another and are fixedly joined to one another in line in an integral block assembly determined by a length L;
- one of the at least three hydraulic cylinders in the integral block assembly is provided to adjust the adjustable distance (d) of the dies for opening or closing the dies;
- and
- the other two of the at least three hydraulic cylinders in the integral block assembly are simultaneously movable from the position sensor till the end of the respective stroke toward each other, thereby shortening the length L of the integral block assembly and generating expansion room in between the dies while increasing the adjustable distance (d).
A method for hydraulically controlling a food baking apparatus comprising two dies at an adjustable distance (d) from each other, the two dies being configured for food to be baked between the two dies, the two dies being operable to be opened or closed by adjustment of the adjustable distance (d) by a hydraulic drive system, the method comprising:
- providing the hydraulic drive system with at least three double-acting hydraulic cylinders each having a respective stroke;
- providing each of the at least three double-acting hydraulic cylinders with a respective position sensor;
- mounting the at least three double-acting hydraulic cylinders in line in an integral block assembly having a length L;
- moving one of the at least three double-acting hydraulic cylinders in the integral block assembly to adjust the adjustable distance (d), thereby opening or closing the dies;
- and
- simultaneously moving the other two of the at least three hydraulic cylinders in the integral block assembly from the respective position sensor optionally till the end of the respective stroke towards each other, thereby shortening the length L of the integral block assembly and generating expansion room in between the dies while increasing the adjustable distance (d).
