DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention relates to a method of and apparatus for automatically making food products such as bread, cakes and the like.
The invention is more particularly related to a baking apparatus for automatically making food products in piece form from dough-like substances. The apparatus may for example comprise a housing containing holding means adapted to be affixed to either end of a flexible sealable bag containing the ingredients for the doughlike substance, and a dough preparation station having an upper and a lower slit forming slit openings. Kneading means are included for mechanically working the ingredients in the bag, and the apparatus provides for relative movement between the bag and the kneading means so that the ingredients are kneaded into a dough-like substance. A heat treatment station is in said housing in which the kneaded dough-like substance is baked.
Baking e.g. bread for household purposes is a relatively complicated, time consuming, work intensive and messy business. Due to the fact that the quality of the bread to a certain extent depends on the fermentation time and that the fermentation procedure has to be performed under the correct conditions, which takes a relatively long time, there are few people who have the privilege of eating fresh home-made bread for breakfast.
In the EP-A No. 0 113 327 there is disclosed a baking apparatus of the above mentioned kind which can produce bread automatically without soiling various vessels and utensils, as the mixing and kneading operations of the dough takes place in a flexible sealable bag containing the necessary ingredients for the dough.


SUMMARY OF THE INVENTION

If the baking apparatus is to be of practical use it should be able to cope with variations in the type and quality of the ingredients used and be able to produce a variety of baked products. There is then a need to provide the baking apparatus with the necessary instructions to take account of these variations in a reliable and effective but uncomplicated manner.
The invention is defined in the claims below to which reference should now be made.
In an embodiment of this invention the baking apparatus receives a bag and reads from the bag a first identification indicia which confirms to the apparatus that the bag is of a type usable in the apparatus, followed by a second command indicia which instructs the apparatus as to the parameters appropriate to the particular baking operation required. Either or both of these indicia may take the form of a bar code, the apparatus then including an appropriate bar code reader.

DESCRIPTION OF PREFERRED EMBODIMENTS

The baking apparatus illustrated is basically of the type described in EP-A No. 0 113 327 and consists of holding means 11, a flexible bag 12 attachable thereto and a common dough preparation and heat treatment station 13,14. The whole arrangement is located inside a thermally insulated casing 15.
The flexible bag 12, an embodiment of which is shown in FIG. 6, is used as a transportation package for the dry ingredients from the producer to the user and as a vessel during the preparation of the dough and possibly also during the baking. The bag 12 must therefore withstand rough mechanical treatment and preferably also contains a second bag or a separate compartment, in which is contained the liquid required for preparation of the dough. The compartments containing the dry ingredients and the baking liquid
