Dairy & Liquid Food
SANI Membranes is a trusted partner for filtration in dairy and liquid food applications
The Vibro® technology can replace microfiltration and ultrafiltration ceramic and plate-and-frame cross flow systems with easy-to-service, low-cost systems. The Vibro® technology makes it possible to work with very high viscosities in a simple and affordable solution with minimal energy consumption being used for pumping, thereby also minimizing cooling requirements.
As the transmembrane pressure (TMP) is uniform in the entire system, the separation cut-off is very sharp. Meaning that a better fractionation of molecules is achieved. The Vibro® technology can work with exceptionally low TMP (e.g. 0.1 bar), which enables true continuous microfiltration.
Low energy consumption – Up to 95% reduction
High concentration, viscosities and solid loads – replaces costly ceramic or P&F solutions
Gentle product handling – Minimal pump shear
Reduced CIP time – Fully drainable membrane modules
Ideal separation – better products, sharper cut-off
The Vibro® technology is typically used within the following separation steps:
Initial separation of cells/solids/large molecules from proteins/small molecules/water:
The Vibro® technology makes it possible to run continuous microfiltration, making the solution ideal for separation of raw streams. This enables you to achieve a high yield and better-quality products in both permeate and retentate.
- The Vibro® technology can handle high solid loads and high viscosities due to the open design of the Free Flow Plates™.
- For fractionation of raw streams, the Vibro® technology can achieve an extremely high recovery due to the low TMP, which makes it possible to control the fouling layer and achieve high transmissions of target compounds.
Concentration of protein:
The Vibro® technology makes it possible to achieve a high concentration of protein due to the open and clean design of the Free Flow Plates.
The Vibro® technology creates the following benefits
Reduced energy consumption
With the Vibro® technology, it is possible to reduce the energy consumption by up to 95% since the cross flow pump is redundant.
With the Vibro® technology the separation is improved due to the uniform TMP, which ensures that the membranes’ molecular weight cut-off (MWCO) is uniform throughout the system – Even for industrial plants.
Reduced product shear
With the Vibro® technology, the cross flow pump is replaced by vibrations. This enables very gentle filtration, thereby reducing product shear to a minimum.
Actual continuous microfiltration
With the Vibro® technology, it is possible to do actual microfiltration due to the low and uniform TMP.
The Vibro® technology is in the following example applied for a Greek Yoghurt process where the cultured skim milk is concentrated to Greek Yoghurt.
The cultured milk is processed in a Vibro-I unit with 3 steps. The first step is with plug flow and the second and third step is with mix flow (a very slow cross flow – mixing the retentate in the unit). The shown unit is for 1200 l/h skim milk with 450 l/h concentrate produced. The system footprint is 2 x 2 meter and the power consumption for pumps is less than 5 kW. This also means that only very little cooling is needed. The system is simple to use, easy to CIP and requires minimal control.
