Landucci company has developed an innovative Cutting Unit called TWIN-FLOW TFC with the aim to create a machine that has a revolutionary ventilation technology, in addition to optimizing all the features in line with the requests of an increasingly demanding clientele:
1 – Easy FUNCTIONALITY and maximum SECURITY.
2 – Reduced MAINTENANCE and Easy CLEANING.
3 – TECHNOLOGIC MANAGEMENT OF AIR FLOWS in the cutting area and for product transportation.
The machine was subjected to scrupulous FEM structural checks and CFD flow analysis, the results of which were then translated into the reality of the pasta factory with extraordinary effects on the pasta. This huge step forward in the technological part, due to the total control of the ventilation functions (TFC), allows us to offer pasta factories a new cutting system, which is not only aimed to cutting the product coming out of the die, but allows to do so respecting the specificity of each shape, without having any compromise between the air flow in the cutting area and that necessary for transporting the cut pasta.
Therefore, in an objective and scientifically proven way, we have achieved all the objectives required by the market
TECHNICAL FEATURES:
BEARING STRUCTURE: made of electro-welded painted steel (white RAL 9010) formed by an upper frame fixed to the press structure and by a supporting column resting on the press foot for lifting and rotating the cutting head. The vertical movement (up- down) of the cutting head is electro-mechanical on prismatic guides to ensure maximum stability and precision of coupling with the head in maximum safety for the operators. The rotation of the mask is manual in order to optimize the cone insertion and reduce shape change times. The ergonomics of the machine structure eliminates any obstruction on the ground and in front of the shaker to facilitate all the necessary operations. The machine is equipped with certified ladders to allow operators to access and move in complete safety for die change operations, assembly of penne cutter cones and inspection of the extrusion area.
ELECTRIC LIFTING OF THE MASK: the lifting system of the mask is the best in terms of precision and rigidity. In fact, the mask slides on 4 high precision prismatic guides, thus avoiding misalignment with the head. The lifting of the mask is carried out by a gearmotor + worm system, thus replacing all those traditional lifting systems (hydraulic and / or pneumatic) that are less safe and require numerous maintenance interventions. The stopping points in the ascent and descent path can be managed in a personalized way by means of an ingenious system integrated by PLC (Patent pending).
CONE QUICK CHANGE SYSTEM: the simple manual rotation of the mask eases the change of the cone and / or the purging of the head. The cone mounted on the head rests on a system of load- bearing spheres to simplify the centering operation with the die. The rotation of the cutter also facilitates the maintenance and cleaning of the press front as much as possible as well as allowing space for the possible installation of farfalle machines.
CUTTING AND VENTILATION MASK: made of stainless steel, it is suitably shaped to convey the product on the transparent slide for loading the shaker, avoiding product deformations. The mask is illuminated by LED lamps to allow a total view of the cutting surface. The mask can be fully inspected for complete cleaning and sanitation.
MANAGEABLE VENTILATION: This is the revolutionary feature that distinguishes the cutting unit, in fact the mask is equipped with two fans, located on the machine side, from which two air flows are produced, one dedicated to the ventilation of the product transport slide and the other dedicated to the technological action of product cutting and pre-drying. These two flows are suitably conveyed and uniformly distributed to obtain maximum efficiency in the concerned areas. The fans can be independently managed by means of an inverter, thus allowing the control of the amount of air according to the size recipe for both the transport and the technological cutting action. The air can also be heated through thermo-resistances integrated into the machine with the possibility of adjusting the temperature according to the environmental conditions of the pasta factory.
CUTTING SYSTEM: the knife is controlled by a motor which allows to have a constant cutting torque from 30 to 400 rpm. The motor is positioned inside the cutting head, to reduce the dimensions of the head itself in an easily accessible position. The machine is equipped with a set of knives with 1, 2 and 3 blades.
CONTROL SYSTEM: the machine is equipped with a PLC for the complete management of functions and alarms and a control panel on the mask board in an ergonomic position and from which it is possible in a simple and intuitive way to activate all the functions.
SAFETY SYSTEMS: the machine is equipped with the following safety devices: mask-head contact sensor for knife rotation consent, cutting mask occlusion sensor to detect any product clogging, load cell to avoid any overload of the structure.
OPTIONAL = FRESH PRODUCT WASTE: by means of a loading hopper with internal tilting part activated automatically by PLC, which allows to avoid introducing the incorrectly formed product into the shaker during the start or stop phases of the screw.
