Abstract:
An apparatus for producing enveloped food products in which an outer food material envelops an inner food material, said apparatus comprising:a linear conveyor, having a given width and length, for conveying the enveloped food products, which are set on the linear conveyor in multiple rows across the width of the linear conveyor in the traveling direction along the length of the linear conveyor; and multiple units, located above the linear conveyor, each for producing the enveloped food products to be set on a separate row of the multiple rows of the enveloped food products on the linear conveyor, wherein multiple units are arranged in parallel such that their lengths are located along the traveling direction of the linear conveyor, each unit including: i) a first feeding means, having an outlet for receiving the inner food material and for feeding the inner food material from the outlet; ii) a second feeding means, having an outlet for receiving the outer food material and for feeding the outer food material to the outlet of the second feeding means, wherein the second feeding means is opposite the first feeding means; iii) a pair of vane pumps, one of which is provided for the inner food material and the other of which is provided for the outer food material, wherein each vane pump has an inlet near the corresponding outlet of the corresponding feeding means and has an opposite outlet and wherein each vane pump receives the corresponding food material from the outlet of the first feeding means at the inlet of the vane pump, and wherein each pump continuously pumps out the received food material from the opposite outlet of the vane pump in a predetermined quantity; iv) enveloping means, located between the opposite outlets of the vane pumps, for causing the inner food material from one vane pump to envelop the outer food material from the other vane pump so as to form an elongated product in which the outer food material envelops the inner food material and for extruding the elongated product from the enveloping means; and v) cutting means, located under the enveloping means, for cutting the elongated products so as to form a plurality of enveloped food products wherein in each product the outer food material envelops the inner food material, and for dropping the cut products on the linear conveyor such that the dropped and cut products form a predetermined row of multiple rows of the enveloped food products on the linear conveyor.
