Problems solved by technology

However, said document does not take into account other external factors affecting this process, such as the vibrations generated in the head assembly transmitted from the rotating elements included in the extruder, mainly the motor shaft and counter-rotating elements. Gears to the rotary drive system of the rotary nozzle - a nozzle commonly used in the extrusion technology of artificial collagen casings

Embodiment Construction

[0047] In view of the foregoing drawings and in accordance with the numbering employed, an example of a preferred embodiment of the present invention can be seen in the accompanying drawings, including the parts and elements described and identified in detail below.

[0048] specifically, figure 2 A preferred embodiment of an extruder head for forming tubular food films is shown by way of example. In particular, the wet extrusion of the collagen casing 9, also including the internal coagulation, is carried out directly outside the casing 9 in a coagulation bath. The external coagulation liquid is recirculated from the external coagulation bath to the casing 9 through the recirculation line 6 to refresh the external coagulation liquid.

[0049] The extruder has a body 1 immersed in a coagulation tank 7 containing an external coagulation liquid. The body 1 comprises a plurality of lumens into which the collagen paste 8 is fed under pressure through a conduit (not shown) throu...

Abstract

A system and method for controlling the vibrations of the mandrel (5) of an extruder head used in the formation of a tubular film of food products, the extruder head of the type submerged within a coagulation tank (7) and the rotating elements of which are driven by an electric motor. The control method includes: detecting, by a proximity sensor (13), vibration experienced by a free end portion (5b) of a mandrel (5); transmitting a signal detected by the proximity sensor (13) to a controller (17) that calculates, on the basis of the signal, a necessary correction of the rotation frequency of the motor such that the rotation frequency of the motor is away from a harmonic frequency of the natural oscillation frequency of the mandrel (5); and modifying the rotational speed of the motor until the calculated frequency correction is reached such that the spindle (5) does not resonate.

Description

technical field [0001] As stated in the title of this specification, the present invention relates to a control system for monitoring and regulating the state of vibrations induced on a mandrel included in the extruder head. More specifically, the extruder is of the type that includes counter-rotating nozzles commonly used in the formation of food tubular films or edible artificial casings. Background technique [0002] Currently, casing extrusion techniques based on fibrous collagenous substances are used for the formation of meat casings of the type used to wrap food products such as sausages or stuffed foods, by means of which tubular films of variable length are obtained. [0003] The tubular extrusion of such casings for food is an extremely delicate process, given the requirements for regularity in size and performance of casings for food, uniformity of diameter along the indefinite length of the casing - also known as Specifications - is one of the most important par...
