Stabilization of colored alcoholic beverages (liqueurs and spirits)

Home - Application - Food Industry (Beverage Industry) - Vodka - Stabilization of colored alcoholic beverages

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

  • Polishing (clarifying) filtration before bottling for brightness and transparency. 
  • Removal of residual opalescence, colloids.
  • Increasing of product stable transparency during storage. 

It is known that alcoholic beverages, which include fruit juices and fruit drinks, are complex colloidal systems, and their balance may disrupt due to some changes of external conditions. Long-term observations show that filtering them through the filter cardboard does not always guarantee the beverages to be stable for a long time. 

Multistage cartridge microfiltration using various filter materials considerably extends the period of product stable transparency.

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 based on cartridge microfilters before bottling.

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.

Such combination as "pre-filter - 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 to preserve all the organoleptic properties of the beverage.

Equipment. Laboratory equipment for the selection of optimal filtration scheme

KFM and KFV filter capsules 

Purpose - capsules are designed for fast and effective filtration of small volumes of liquids and gases. Capsule filter cartridges (KFM or KFV) allow carry out small-scale pilot tests at early stages of the development of the filtration system to select the optimal combination of filters, especially for the treatment of hard-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 (single-use).

Description

Capsules are ready-to-use inexpensive complete non-detachable filters, composed of polypropylene housing with a press-fitted mini cartridge. The structure allows use mini-capsules without installation of steel equipment. 

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

 All Technofilter filter cartridges can be produced in the form of capsules.

Pilot filtration plants
