Nitor Cross-Flow Filtration Systems
The Padovan NITOR Cross-Flow Filtration System was developed in 1989 as an answer to the growing issues posed by Diatomaceous Earth in Europe.
TMCI Padovan (Italy) experimented for several years with varioussolutions to these problems leading to the development of a unique system of cross-flow filtration, which is both respectful of the specific organoleptic qualities of wine, while also being highly efficient.
It is all in the membranes.
The specific advantages of using cross-flow filtration technology are:
- No Diatomaceous Earth usage.
- No negative D.E. flavor effects on the wine.
- Minimized labor costs as systems can be automated.
- Greatly reduced wine losses during filtration.
Historically there were some disadvantages seen with cross-flow filtration technology:
- Limited working life of the filtration membranes.
- Poor efficiency of the filtration over extended time periods especially when filtering wines with high NTU levels and/or the presence ofBentonite.
- Problematic heating of the wine during filtration.
- The membranes used by Padovan are specifically designed for verylong life, this is reaffirmed by the length of the warranty offered which is 3 years.
- Filtration efficiency is optimized by the on-board PLC, using a “managed”approach which is the only way to efficiently filter wine.
- Issues of heating during filtration are solved by the unique modular approach to filtration construction.
Membranes - Two major types seen in the wine industry.
- Ceramic
- Organic
General Rules for Organic Membranes
- Thinner membrane capillary walls give shorter useful life and less chemical washings allowable.
- Thinner membrane capillary walls give lower mechanical resistance.
- Smaller internal diameters will not work well with products rich in suspended solids.
Nitor Cross-Flow filtration systems
TMCI Padovan cross flow filtration systems use a unique polyolephin in the membrane construction with symmetrical pores and a nominal porosity of 0.2 microns.
- Membrane modules are assembled by Padovan for complete quality control.
- Proven longevity, several units with over 12 years continuous running without membrane replacement.
- Highly respectful of wine quality.
- Warranted for 3 years.
TMCI Padovan cross flow filtration systems are available in three versions each with distinct advantages.
- Nitor CA Series Fully Automatic (from 120 m2 to 800m2)
- Nitor CSA Series Semi Automatic (from 40 m2 to 240m2)
- Nitor Smart Fully Automatic (either 40 m2 or 80m2)
Nitor CA Series Fully Automatic
The CA Series has the unique advantage of being expandable without changing the base machine configuration simply by adding modules composed of four membranes 40m2 or 80m2 (for the XL version)
Nitor CA Series Fully Automatic…….”MODULARITY”
This modularity gives several very significant advantages;
- Expandability. CA series units can be expanded as standard all the way to 400m2
- Selectable surface area for small and large lots, a 400m2 filter can also be used to filter very small lots of 800 liters or less.
- Reliability as multiple recirculation pumps are used.
- Less than 1oF temperature pick up, because of the use of low rotational speed pumps (1.450 rpm) giving low linear flow rates during recirculation.
Nitor CA Series Fully Automatic
The CA Series has a high level of automation giving many advantages for process efficiency
- Fully automatic programmable back washing during filtration.
- Fully automated cleaning.
- Programmable flow rates.
- Data storage and retrieval.
- PLC optimized filtration efficiency.
- Programmable for end of cycle cleaning without operator.
- Selectable filtration surface area.
- On-board flow and integrity testing.
- Available in sizes from 40 m2to 400 m2
CA Series advantages continued....
- 3 years membranes warranty.
- Independent of the cellar.
- Allen Bradley PLC as standard.
- Network integration possible.
- Efficient filtrations at high turbidity for extended time periods.
- Reduction in product losses thanks to scavenger filtration either by nitrogen or by valves.
- Inert gas sparging during filtration for less than 0.1mg/l dissolved oxygen pickup.
Optionals
- In-line filtrate turbidity monitoring and reporting.
- In-line filtrate addition dosing.
- Iso-baric configuration for sparkling wine filtration.
- Inlet/outlet manifolds for tank management and blending
Filtration....and TMCI Padovan Automation
- Fully automatic and programmable yet very simple and intuitive to operate.
- PLC control with multiple levels of password security.
- Automatic protection of membrane to prevent fouling.
- Designed to suit your needs.
Nitor CSA Series Semi Automatic
The CSA Series of Semi Automatic filters features the same modularity as the CA Series but with a lower level of automation.
- Fully automatic programmable back washing during filtration.
- PLC control.
- Constant monitoring of flow and pressure with automatic shut off.
- Constant inert gas sparging of head spaces during filtration.
- 3 years membrane warranty.
- Available in sizes from 40 m2 to 400 m2
Nitor Smart Series Fully Automatic
The Smart Series of Fully Automatic filters features the same level of automation of the CA Series.
Designed for applications where space is at a premium.
- Fully automatic like the CA series.
- Fully independent of the cellar.
- Can be located easily by one person.
- Can be moved by forklift with built in channels.
- More filtration surface area per sq.ft of floor surface than any other system available.
- Available as either 40 m2 or 80m2
Optional automatic C.I.P. system with on-board hot water production
Electric switchboard, made of stainless steel. connected to the filter main PLC for the automatic execution of the following phases:
- Rinsing with warm water,
- Sanitization with caustic solution,
- Rinsing with warm water,
- Neutralization with citric acid solution,
- Rinsing with warm and cold water.
Optional turbidity meter
- Stainless steel cell including two light sources and two miniaturized photocells.
- One cell is directly illuminated from a light source, while the other receives only the reflected light from particles suspended in the liquid.
- The reflected light and the direct light ratio is converted into a signal.
- This instrument is not sensitive to colour or temperature changes.
- Graduated display indicating the degree of turbidity in NTU units.
Customized filter designs available.
The strongest membrane warranty available.
