Ice grape crafts to create high -end wine, ice wine processing equipment promotes production
“Things are rare” to confirm people’s recognition of special and unique things. In recent years, as the younger generation of consumer groups have continued to rise in the pursuit of affection and quality of life, conventional red wine has not met the needs of minor valuation. Ice wine products with rigorous processing and less output have become new pets. Skin slag pressing frame column press and ice wine filtration equipment has also become a strong support for the booming wine industry.
Ice wine is a sweet wine made of natural frozen grapes on the grapes, which are high -end wine categories. Because of its processing processes, it can only be produced in some low -temperature areas. At the same time, although its brewing process is basically similar to red wine, the requirements in processing are more stringent. At present, the production areas are mostly distributed in Canada, Germany, Xinjiang, Northeast my country and other places in China.
The production process of ice wine contains many strict processes such as grape frozen picking, sorting, squeezing, fermentation, low temperature storage, and filtering. The grape ingredients used for winemaking alone need to continue to experience frozen and sun irradiation in the severe cold environment after maturity, and continue to freeze for more than half a day in the environment of minus 8 ° C for further processing.
In the subsequent squeezing session, in order to maintain the form of ice grapes, it is necessary to use a low -temperature device with a skin residue squeezing frame -type pressing machine. Keeping the processing environment temperature at minus 8 ° C with the help of low -temperature equipment is a necessary foundation. Ice grapes are relatively hard. It is necessary to adjust the controllable hydraulic pressure gauge system of the pressing equipment to make it have great pressure to better press the juice to experience the raw materials for dehydration outdoors.
According to personnel from a domestic ice wine production company, the crushing rate of ordinary grapes is basically about 70%, while the juice rate of ice grapes is only between 5%and 20%, and the overall output is very low. Therefore, ice wine is also more precious, and is called “golden liquid” by the industry.
The low juice rate of ice grapes also means that the sugar in the grapes is doubled. In the subsequent fermentation session, a variety of impurities such as fiber and colloids in grapes will emerge, which will cause the fermented ice wine to be very turbid. Traditional wines generally use freezing filtration and other methods at this stage to separate liquids and other impurities. However, due to the low accuracy of the traditional filtration, the impurities of some macromolecules cannot be completely separated, resulting in not clarifying the ice wine, and a long -term placement will still produce a certain turbid precipitation.
At present, Ice wine filtration is mostly two forms: natural clarification and processing equipment clarification. Natural clarification is mainly due to static settlement and tanks of layered liquids. The overall operation time is longer and complicated. The ice wine filter clarification equipment can screen the molecular level impurities by using polymer membrane materials, so that the effective ingredients and liquids can achieve the rapid and deep clarification of ice wine through the surface layer of the liquid, and better guarantee the quality of ice wine.
The fine production process and scarce finished product of ice wine are important influencing factor in the ranks of high -end wine. With some processing equipment and process technologies specifically used for ice wine production in recent years, limited ice grapes may be better. Transforming into ice wine, increasing the production of ice wine, and bringing sufficient products to the market.
