DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method and a device for manufacturing products, preferably food products such as pancakes, waffles, meat balls etc., where the product material initially in a more or less liquid state is fed into the device and through the supply of heat or cold is given its final, more solid state.
Food products such as pancakes, waffles, meat balls and similar have hitherto not been manufactured in a rational manner. The production has required either several persons and much equipment, which made the products expensive, or has taken a long time, which, when a large number of the products shall be made, is unacceptable.
The object of the present invention is therefore to provide a method and a device which permit rational production also of large amounts of particularly food products such as pancakes, waffles, meat balls etc.
This object is arrived at while the method is characterized by the fact that elements between which the products are to be formed, are located close to each other in the device according to the invention; that the elements located close to each other are brought together; that the product material is injected into product-forming spaces defined between the elements during the bringing together thereof; that heat or cold is supplied to the elements for forming the products by heating or cooling the product material in the spaces between the elements; that the elements are moved apart when the products are finished to provide access to the products; and that the finished products are removed from the elements.
The device for carrying out this method comprises elements which can be located close to each other and be moved apart as well as brought together, and which have at least one recess on at least one side of each element so that the sides facing each other on two elements mounted close to each other between them define at least one product-forming space, whereby each element includes at least one guide portion which cooperates with a guide means for locating the elements in a correct space-defining position close to each other and guiding the elements while they are moved apart or brought together, whereby each element includes at least one feed portion for injecting the product material into the spaces between the elements by means of a feed device, whereby the elements include heating and/or cooling means for heating or cooling the product material in the spaces between the elements, whereby the guide means includes a limit stop against which the elements are pressed by means of a driving device for bringing the elements together when the product material is injected into the spaces therebetween, and whereby the guide means also includes at least one stop means which the guide portions of the elements are brought to engage when the elements are moved apart for removal of the finished products.
The device according to the invention can be operated by one person, despite its very high capacity, since the device can be operated fully automatically. Thus, the products are cheap to manufacture. The method and device according to the invention may also, as stated above, be used for other products than food, e.g. stearine candles.
The abovementioned and other characterizing features of the invention and the advantages therewith will be further described below with reference to the accompanying drawings, wherein
FIG. 1 is a perspective view of two elements for the device according to the invention;
FIG. 2 is a section through one of the elements in FIG. 1;
FIG. 3 illustrates schematically, with an exploded view and in perspective, four elements in a position where they are brought together for injection of product material;
FIG. 4 is a view corresponding with FIG. 3, but illustrates the elements moved apart for removal of finished products; and
FIGS. 5-9 illustrate an embodiment of the device according to the invention after location or mounting of the elements and during the different steps in the method according to the invention.
Thus, FIG. 1 illustrates in perspe
