Apart from filtration, there are many aspects of winemaking that fall into a more general category. Among these are continuous stabilisation, flotation, thermovinification and grape sampling.
Kristalstop Continuous Cold Stabilisation
With flow-rates between 2.000 and 20.000 l/hour (higher capacity on request), the Kristalstop gives you the capability of stabilising your wines in as little as 90 minutes! The scraped evaporator allows the product to be chilled to near freezing in order to cause immediate crystallization. The 20 model is semiautomatic, while the 40-60-100-150-200 models are fully automatic. On request, the plant can be built with “PED” testing suitable for sparkling wine.
Wine conductivity after the treatment is continuously monitored with automatic recycling in order to achieve your specified result. Moreover, the system is provided with hydro-cyclones that continuously separate the formed crystals for re-seeding.
Flottaflux Continuous Flotation Systems
The Flottaflux unit assures a continuous separation of solids from grape must and fruit juices by utilising the “dispersed gas flotation” process. Flotation is the opposite of the settling process whereby air or inert gas in injected into the juice, then the finely subdivided bubbles combine with suspended solids making them lighter and causing them to rise. Before flotation the juice is enzymed and treated with clarifying agents in order to flocculate its colloidal substances.
Standard machines range from 15,000 L/h to 60,000 L/h.
Ambra Ion Exchange Plants
The Ambra stabilisation systems operates on wines and musts at ambient temperature using cation resins. They are engineered to obtain perfect flow during stabilisation and regeneration, with complete drainage at the end of a cycle. Easy to use, they reduce stabilisation costs with no reduction in colour or colloidal changes.
Red Hunter Thermovinification Systems
The Red hunter is a continuous vinification line for the production of red, rose and deep red wines with a superior alcohol content and a constant quality. With energy savings of up to 35% when compared to traditional thermovinification systems, the Red Hunter can achieve more colour intensity in 1 hour than 10 days of cold vinification. The spiral heat exchangers are gentle on the mash, producing approx 3-5% of lees.
Standard models are from 5 to 60 tonnes/hour.
Grape Sampling Systems
Relco Instruments provide complete systems for the analysis of grapes, with many different options available. Their flagship unit is the WP analyser, that allows to you obtain sugar content, pH and temperature directly on the sampling head. The sample is returned to the truck so there is no need for a transfer of juice and the associated disposal (loss!) of the sample.
They also have lab based systems that allow for the analysis of further details such as total acid (TA) and colour.
