Features and applications
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 media considerably extends the period of product stable transparency.
The main applications of NPP 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.
Recommendations for filter cartridges
Filter cartridges and equipment for polishing filtration and stabilization of colored alcoholic beverages
To stabilize alcoholic beverages after pretreatment on a filter press, we suggest using a two- or three-stage filtration scheme before bottling based on cartridge microfilters.
The choice of a filtration scheme is carried out taking into account the type of product, its tendency to opacity, system performance and individual requirements of the Customer.
The combination "pre-filter – finishing membrane filter" increases the reliability of the technological process, ensures the best quality of the drink, maximum productivity, long resource and efficiency of the entire system.
The used filter media help to preserve all the organoleptic properties of the drink.

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 one-piece filters, which are mini-cartridges soldered into polypropylene holders. The design allows the capsules to be used without installing a steel filter holder.
The capsule filter has a high-strength, sealed polypropylene housing and is equipped with various filter media with a wide range of pore sizes. The flush capability allows the capsule filter to be reused until the entire filter surface is exhausted.
All NPP Technofilter filter cartridges can be produced in the form of capsules.
Pilot filtration systems
Multifunctional pilot filtration system for filtration of small volumes of products, ingredients, for pilot filtration and testing of various technologies
Purpose
They are used in the food industry for the production of beverages and are intended for fine purification of vodkas, wine, tinctures, liqueurs, and other alcoholic and non-alcoholic beverages.
It can be used for industrial purposes for filtration of drinks (throughput 250 - 1000 l / h), as well as for testing of filtration technologies in laboratory conditions.
Pilot filtration systems for souvenir lines can be completed with a control panel with an automatic circuit breaker and frequency converter.
