JUCLAS microfilter unit, type MICROFIL, year of manufacture 2008, serial number IMMICRO100

This filter line unit has a 12+12 cartridges wine line, so it could reach 120hl/h of wine production, with a 0.45-micron cartridge on the last filtration unit.

Same for the waterline, they have 8+5 cartridges housings, so they can reach 50hl/h of 0.45 micron of microfiltration water.

The microfiltration unit is equipped with Δp control of central filter housing and final filter housing.

This equipment shows the measured Δp and the alarm set for each housing. This equipment has an electrical switchboard. This filter has CE Certification. 

All machine parameters:

The microfiltration unit is a system for the cold filtration of wines, including sparkling wines.

Filters have an important role in every industrial field. Filtration means to separate particles of a fluid (liquid, gas or vapour) by making the fluid cross a permeable barrier (i.e. a material which contains holes or pores through which fluids can pass). Where particles are a significant portion of the fluid, the process can be described as a solid collection. Where they represent only a small part of the total (0,01% or less), the process is term fluid clarification. In most cases, filters are used to remove particles of sizes that can vary between fractions of a micron up to 40 microns and beyond. The diameter of the smallest point a human eye can see directly is about 40 microns.

One micrometre is one million part of a millimetre. It is commonly abbreviated as “micron”, and its symbol in the IMS (International Metric System) is “µm”.

Overall weight



The machine has been subjected to sound tests to ascertain the level of sound emitted in the air. Recordings were made in conformity with existing norms and provided a value of continuous pondered equivalent A sound pressure at the work station of less than 70 dB (A).

Preparing for microfiltration (starting the work)

Completely empty all sanitizing solutions from the microfiltration plant and the bottle filler, then rinse with cold micro-filtered water for about 10 minutes to remove residues.

In order to heat the inspection circuits and tubing gradually, send hot water at 70-80°C through; empty the hot water and start sending in steam. Keep all condensation vents open in order to avoid a “plug” effect from condensation in vertical tubing and in siphons if these are present. Dry saturated steam sterilization must last at least 20 minutes from the moment the temperature inside the machine reaches 121°C (1,1bar).

If there is no steam a sanitizing treatment can be achieved by using hot water at 80°C for 30 minutes.

Cool  immediately  by  using  warm  micro filtered  water  (if  for  some  reason  this  is  not  possible immediately pressurize the bottle filler with micro filtered nitrogen), followed by cold micro filtered water. This is in order to respect graduality in temperature shifts.

In the meantime, perform the “integrity test” on testable filtering elements; the test is done at 20°C by gradually pressurising upstream filtering elements that have first been wet with cold water. Upstream

valves must be shut while downstream valves must be open (make sure that there isn’t a retention valve between the filtering elements and the first downstream valve as this would invalidate the result;

after a few seconds necessary for the pressure to stabilize around 1000 mbar, bring pressure to 1240 mbar and then measure 600 seconds with a chronometer. During this period the pressure must remain constant or within the tolerance limits which depend on the housing volume and on the number of filtering elements. This information will be provided by our technicians and could be changed since the continuous update of our materials doesn’t exclude, in principle, that the values may change without the filtering system changing.

As an example, one housing with one 750 mm nylon 66 filtering element of 0,45 µm thickness must not be subjected to any variation, while 11 filtering elements of the same sort located in a single housing could undergo an 85 mbar pressure decrement, approximately.

Microfiltration and bottling

Gradually change the housings content from water to wine and start sending the wine to the bottle filler. If the lay-out permits this, send cold microfiltered water to the rinser, after you’ve opened the safety valve that is located in the by-pass.

End of bottling

Once bottling is finished, or rather once the supply to the biological stabilization plant is finished, one needs to bottle the wine present in the tubing and housings. For this purpose, start sending in nitrogen upstream from the first filter.

Once the above operation is finished, start washing the bottle filler and regenerating the filtering elements using cold microfiltered water (if the amount of water available is not sufficient to wash all parts at the same time, proceed step by step starting with the bottle filler and then moving on to the filtering elements). Rinsing must last at least 10 minutes, with flow rates greater or equal to that of the wine and without pouring waste water from one housing to the next, but rather emptying it out. This type of washing is termed " parallel washing".

Empty out the washing water, send a luke-warm 1,5-2 % aqueous solution of V SANEX (chloro- alkaline detergent) only into the bottle filler. In the meantime, start regenerating the filtering elements by sending hot microfiltered water at 60-70°C into them, making sure that you empty the used water from each housing.

Once the filter regeneration is over, start colling them down with cold microfiltered water.

When the machine has reached room temperature, send a 0,2 % solution of BIOCIDA V05 in rigorously cold water through all the microfiltration units’ circuits.

The machine can be kept filled with the solution until the next working period, as long as the inactivity period does not exceed 7-10 days. If it does, we advise replacing the sanitizing solution (as it tends to lose its efficacy over time).

The buyer should  chenge all the gaskets, he can order them directly to Ju.Cla.S factory.
