ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a method and a device for shaping and portioning a soft, pasty product within a tubular casing of foil material according to the preamble of the independent claims.
2. Description of Relevant Art
Methods and devices of this type are known, for example, in the field of foodstuffs technology for portioning cheese into slice-like, plate-shaped form. DE 195 01 106 A1 of the same Applicants discloses a method of this type and the associated device. In this case, the product provided with a casing is shaped between two shaping elements, which are preferably constructed as circulating belts with webs, and is portioned into individual slices. However, in this case the product is portioned in a cold, relatively solid state.
A shaping device for packing a soft product is known from DE 38 41 945 A1, in which the encased product is also guided between two belts provided with clamping members, and is thereby provided with its intended shape. Since the product is processed in a relatively fluid state in this case, it is difficult to obtain a specific weight for each slice of cheese. Consequently, the belts which face one another extend in this case between two parallel, smooth plates, whose distance from one another is variable. In this manner, it is possible to vary the volume of the portions formed in the casing between successive clamping members. However, a disadvantage in this case is the relatively complex construction, since it is necessary to provide the adjustable plate arrangement within the circulating belt drives. The belts slide continuously along the plates, so that a high degree of belt wear has to be taken into account.
It is therefore the object of the present invention to propose a method and a device for shaping and portioning a soft, pasty product, in which the quantity or the volume of the product supplied to the shaping and portioning station can be adjusted at any time.
SUMMARY OF THE INVENTION
This object is attained according to the invention by the features disclosed in the characterizing part of the independent claims. In particular, in one aspect of the invention, a method for shaping and portioning a soft, pasty product within a tubular casing is disclosed. The method includes the steps of passing a product encased within a tubular casing through a metering station, metering a quantity of the product per unit of time, supplying the metered product to a shaping and portioning station, and portioning the metered product into portions in the shaping and portioning station.
In another aspect of the invention, a device for shaping and portioning a soft, pasty product within a tubular casino made of a foil material includes a shaping and portioning station, to which the encased product is supplied. The encased product leaves the shaping and portioning station in divided portions. A metering station is arranged directly upstream of the shaping and portioning station, in order to meter a quantity of the product supplied to the shaping and portioning station per unit of time.
Advantageous embodiments and further developments of the invention form the subject matter of the dependent claims.
In order to meter the quantity or volume of the encased product supplied to the shaping and portioning station, a metering station is provided according to the invention, which is arranged upstream of the product advance immediately prior to the shaping and portioning station.
