Internal valve vacuum filler

The new generation of vacuum fillers are specifically designed to fill liquid products or sauces into rigid containers such as glass jars, aluminium or tinplate cans. The containers handled may already contain other products such as: fruit, peeled tomatoes, tuna fish, meat, vegetables, etc.

Functions of the machine
The table top chain conveyor delivers the containers to the infeed screw, which is constructed with a variable pitch to facilitate their entry. This screw is synchronised with the infeed starwheel, which tranfers the containers to the filler. At the beginning of the filling area, the containers activate a "no can-no fill" device, which allows the first phase of the operating cycle to commence. The following phases are activated by means of a roller/lever which turns by means of cams joined to a ring concentric to the filling bowl. When the last phase is complete, the containers leave the filler and are subsequently transferred to the seamer.



High strength and reliability

  • St. base containing all drive gears and roller lifting mechanism which are submerged in an oil bath.
  • Lifters in aISI 304 st. st. and rollers made in AISI 440C tempered steel.
  • Container infeed conveyor of slat band chain type with synchronising screw and container entrance starwheel in non-toxic low-wear PVC material.
  • Heavy gauge all stainless steel liquid-holding bowl.
  • Liquid level control positioned inside the tank.
  • AISI 316 st. st. heating coil positioned inside the tank and automatically controlled by a thermo regulator.
  • Thermometer, vacuum gauge.
  • "No can - no fill" device.
  • Seamer drive attachment for synchronisation.
  • Vacuum group comprising liquid ring high vacuum pump, product recovery tank in stainless steel and recirculation pump which returns product to the filler bowl, possible liquid separator.
  • Electric panel board with IP 55 protection.
  • Control of the machine functions by PLC.
  • Protections in accordance with E.E.C. regulations.



Advanced technology

Zacmi patent valve group The group consists of 2 parts: valve body and rotor in stainless steel and sanitary material. The roller/lever mechanism which controls the rotation of the valve, has been designed after years of research.
It resolves the problems that exist on many machines which have valves controlled by traditional mechanisms i.e. impact of the stars, which rotate with the tank, against fixed cams



.














The advantages of this new system are:

  • reduction of the noise level
  • no need for lubrication
  • total elimination of shock between the stars and fixed cams, which can cause the formation of metallic dust
  • considerable reduction on the maintenance costs
  • correct and constant positioning of the two parts of the valve group (body and rotor)
  • increase of the machine operating speed

The standard operating cycle of the valve consists of three phases:
vacuum application, filling of product and vacuum break.
In the case of high viscosity products, the machine is manufactured for the application of a further filling operation between the second and third phases.





Hygiene
All the product contact part are constructed in stainless steel and food quality material. The base of the machine is covered by a stainless steel tray to recover any product loss. The special design and accuracy dedicated to the construction of all the machine components, assure an extremely easy sanitation process.
Possible automatic washing device (C.I.P.) and filler bowl cover in stainless steel.
