Winegrowers Supplies - Flotation filters, for Must or Wine clarification
Must clarification is very important in order to achieve high-quality wines. Traditionally it has been carried out with either:-
1. centrifuge (separator): high machine cost and high maintenance cost.
2. treatment by Hefe-filter or rotary filter: lower capital cost than a separator.
long waiting time compared with separator,
higher number of bacteria because of the long waiting time,
no solid sludge-cake.
Now there is the process of 'flotation clarification', which has for a long time been used in sewage treatment.
In recent years it has been applied increasingly in the clarification of fruit-wine. Today it is a well-proven method to enhance the quality of wine. It achieves a perfect separation of the sludge from the clear liquid.
This clarification procedure is based on inserting minute gas or air bubbles into the liquid. These attach themselves to the
sludge particles in the fruit-wine and drive them up to the surface of the liquid.
The sludge particles remain there and form into a solid sludge-cake. This cake mass can be continually skimmed off from the surface or you can drain off the clear liquid out through the residue drain at the bottom of the container.
Lower investment cost,
Low or no maintenance costs,
The most rapid processing,
Clarification to a very high degree,
Reduction of phenols by oxygen incorporation (30%),
Clarification of white and red, also heated grape must without colour loss,
Clean wine aromas,
Solid sludge-cake (max 10 to 15 % of the volume) which needs no further processing.
Dosing unit in stainless steel with dosing pump and stirrer. Adjustable dosing flow rate.
Product pump in stainless steel.
Back-lit mirrors to check the product clarity.
Residual filtering with pump through the final disc, internal (with external as an option).
I-ECO Spar Mini: 2880 Euros (£2057)
developed for small producers, throughput: 800 to 1500 litres/hour,
Ebara centrifugal pump on a trolley, 230 Volt, 1.5 kWatt.
The one-tank-circulation procedure enables the flotation and the separation from the clear must in one tank.
Addition of a bentonite and a special high-bloom gelatine is done initially and can be fed in via a special ball valve.
The surface solids produced are extremely compact, so a sharp distinction between clear must and floating solids
is achieved. The must or new wine can be removed after little more than 12 hours.
Air intake unit with manometer, adjustable pressure relief valve.
32-Mainz inlet/outlet, integrated pump protection (pre-filter).
ECO 3000: 3000-6000 litres/hour, 3 kW pump motor,
ECO 10000: 6000-12000 litres/hour,
B50: approx 3,000 litres/hour, 400V / 3.0kW / 2800rpm; 2999 Euros
B80: approx 8,000 litres/hour, 400V / 3.6kW / 2800 rpm; 3699 Euros
