Prexa N – Vortex System

Close Tank Pneumatic Press – Vortex System

The exclusive patent “Vortex” developed by Puleo Srl, puts the idea of pressing under inert gas with nitrogen recovery towards a new and more advanced perspective.

The idea of using inert gas in pressure during working cycle, guarantees a continuous draining action highly greater than any other kind of pressing, with excellent results in product quality/yelds.
A further advantage is the immediate extraction of the must from the cylinder to the storage tank thanks to the “Vortex” created inside the Press. During processing inert gas is continuously filtered to be purified by any pollution due unwanted parts that can be carried by the gas itself.

PREXA N, being a hybrid press, as well as being used in VORTEX SYSTEM MODE, it can work in:

SMART N MODE
Process with gas release. It allows higher performances than standard pneumatic presses with close tank, thanks to the extraction process in closed area, even without nitrogen. The advantage is that the contact with air is minimized, lesser than any pneumatic press with close tank.

CLASSIC MODE (PREXA C)
Its principle of operation is based on that of the pneumatic presses with close tank. The grape must is extracted from inner draining channels and comes out from nozzles to an external collection tray.

 

 

Results

  1. Reduced Working time and high must yield.
  2. Drastic reduction of the must stay inside the press, which is then immediately extracted and separated from the marcs.
  3. Recovery and re-use of inert gas that is constantly purified for next working process.
  4. Easy sanitization of the inert gas recovery tank (food grade vitrified tank).

Innovative details

Automatic pressing cycle 

This device allows automation of the pressing cycles, insuring an excellent quality product and shorter pressing time by customizing the cycles in real time.

Automated washing system 

Automatic washing system of draining channels through water recirculation in all parts that come in touch with the must. This fully automatic system allows a fast cleaning and avoids waste in water: when starting the Press rations the strictly necessary amount of water, then the pump on board let recirculate water though the circuit for the set time. At the end of the process wastewater are discharged.

Crémant pressing program 

Crémant sequential pressing program with pre-laoded recipe according to rules in force.

Membrane fixing system

This device allows quick assembly/disassembly.

 

Prexa Vortex Automations

Everything Under Control

The operator can control the current operation simply going to the control page. An animated graphic screen will shows the nitrogen flow, opening/closing of the valves, start-up of the components.

Once selected the “program”, you can access to the page “Pressing”. In this page you can see number of performing program, performing level, number of repetition of this level, status of the pressing phase, maintaining time expressed in min/sec.

 

 

 

 

KIT VORTEX SYSTEM

The VORTEX COMPRESSOR is a special screw compressor equipped with dryer and specifically designed for the treatment of gas suitable for the food industry, ensuring high quality and safety standards in the final product.

Steril Micrometric Filters

Filter A: it is the first to filter the nitrogen, which is then pressurized and dried by VORTEX compressor.
Filters B, C, D: The VORTEX compressor sends the pressurized nitrogen to these filters, which filter it again and send it to the storage tank.

Inert Gas Recovery Tank

Food grade vertical tank, in compliance with PED regulation, internally vitrified. Besides the nitrogen continuous transferring, the tank stores and preserves it before the next use.

 

MUST TRAY

It is a part of the Vortex System where separation of nitrogen from must occurs.
