Stabilization of color LVI

Stabilization of colored alcoholic beverages.

Technologies and equipment


The main applications of products and technologies of  "Technofilter" in the production of colored liqueurs:


Polishing (clarifying) filtration before bottling in order to give shine and transparency.


Removal of residual opalescence, colloids.


Increase in stable transparency of products during storage.


It is known that the alcoholic beverages, which include fruit juices and fruit drinks, are complex colloidal system which may disrupt the balance of a change in external conditions. Long-term observations show that filtering them through the filter cardboard does not always give an opportunity to get beverages that are stable for a long time.


Multistage cartridge microfiltration using various filter materials makes it possible to extend the period of stable transparency of products to a considerable extent.


Filter cartridges and equipment for polishing filtration and stabilization of colored alcoholic beverages


To stabilize the alcoholic beverages after pre-treatment on the filter press, we propose to use a two- or three-stage filtration scheme before bottling on the basis of cartridge microfilters.


The choice of the filtration scheme is carried out taking into account the type of product, its propensity to opacity, system performance and individual requirements of the Consumer.


Combination "prefilter - finishing membrane filter" increases the reliability of the process, provides the best quality of the beverage, maximum performance, and high resource efficiency of the entire system.


The filter materials used help preserve all the organoleptic properties of the beverage.

Laboratory equipment for the selection of optimal filtration schemes


Filter capsules of KMP and KFV brand


Purpose - capsules are designed for fast and effective filtration of small volumes of liquids and gases. Capsule filters (QPSK or KVV) allow small-scale pilot tests to be carried out early in the development of the filtration system to select the optimal combination of filters, especially for the treatment of difficult-to-filter solutions without investing in stainless steel equipment.


Capsules are especially effective for critical applications, when it is necessary to filter individual batches of the product (one-time use).




Capsules are ready-to-use inexpensive complete integral filters, which are miniaturized soldered in polypropylene holders. The design allows the use of capsules without the installation of a steel filter holder.


The capsule filter has a high-strength, hermetic polypropylene housing and is equipped with various filter materials with a wide range of pore sizes. The possibility of washing allows the capsular filter to be re-used until the entire filtration surface is fully exploited.


All filter elements of the NPP "Technofilter" can be produced in the form of capsules.


Pilot installations


Multifunctional pilot plant for filtration of small volumes of products, ingredients, for advanced filtration and testing of various technologies




They are used in the food industry for the production of beverages and are intended for the fine cleaning of vodka, wine, tinctures, liquors, and other alcoholic and nonalcoholic beverages.


Can be used for industrial purposes for the filtration of beverages (capacity 250 - 1000 l / h), as well as for testing filtration technologies in laboratory conditions.


Pilots for souvenir lines can be equipped with a control panel with a circuit breaker and a frequency converter.


Installation UPF.R3 (1h250 / 1h250 / 1h250) -0.25




Small size and weight allow using the unit even in cramped conditions, it is easy to transfer from one premise to another, to connect to any container;


Single holders allow to reduce filtration costs, to select the most optimal set of filter elements, to filter a small volume of souvenir products or ingredients for the main products (for example, honey), and also to process pure waste.




UPF. P3 is mounted on a frame and consists of:


pump unit (GRUNDFOS Germany);


Filter unit (three single-pass filter holders 250, 500 or 750 mm in height from stainless steel 12Х18Н10Т, complete with manometers);


piping piping, stop valves, rotameter.


Filtration plants


At the request of the customer on the basis of multi-filter holders, manual and automatic control systems such as UPF.R and  UF.A, designed for various capacities (from 0, 5 to 16.0 m3 / h and more). NPP "Technofilter" carries out designing, manufacturing and completing the units in accordance with the individual requirements of the customer.


The plants are compact, mobile, easy to operate. They can be mounted permanently in place, on a frame or on a moving trolley. The units consist of several filtration units, fully equipped (pump unit, measuring and shut-off valves, pipelines, etc.) and are ready for operation.


Absolute-quality series with automatic control


Especially popular in distilleries and wineries are the finishing filtration plants before bottling

The basis of the standard installation is a 2 cascade filtering scheme. The units for filtering wine and LVI are additionally equipped with a filter unit for preparation of service media. Installations are distinguished by a complete set (a set of options) and the degree of automation - it all depends on the filtered beverage and the individual requirements of the Consumer.
