This utility model relates to the technical field of fruit wine brewing catalysts, and discloses a hot-cold alternating catalyst for fruit wine brewing, including a catalytic tank. An inlet is fixedly connected to the upper side of the catalytic tank. A spiral guide vane is fixedly connected inside the catalytic tank. A hot-cold circulation assembly is installed outside the catalytic tank. This assembly is used to activate enzyme activity and yeast metabolism in the fruit wine, promoting the release of aroma substances and the formation of flavor complexity. A heat exchange tube is fixedly connected to one side of the inside of the catalytic tank, and a water supply pipe is fixedly connected to the upper inside of the heat exchange tube. This utility model achieves highly efficient hot-cold alternating catalysis in the fruit wine brewing process, particularly targeting the needs of aroma release and flavor enhancement in black chokeberry winemaking. It also allows for easy disassembly and cleaning of the filter screen, ensuring effective filtration of impurities in the cooling medium and reducing the cleaning frequency of the plate heat exchanger.

The present application provides a kind of flexible brewing process of Marselan grape wine, comprising the following process steps: flexible stem removal and crushing of grape to form grape mash;Grape mash is pumped into fermentation tank to carry out cold soak;The temperature of grape mash is gradually recovered, and then yeast is added to start fermentation, artificial cap pressing is carried out during fermentation;The specific gravity of fermentation liquor is monitored, when the specific gravity decreases to 1, the temperature of fermentation liquor is set to 23-25 DEG C, and heat soak is carried out;Clear juice separation is carried out on wine, free run juice and skin residue are separated out, flexible pressing is carried out on skin residue to obtain pressed juice, and the pressed juice is added to free run juice to form grape base wine;Oak barrel aging;Freeze stabilization and filtration filling are carried out.The flexible brewing process of Marselan grape wine provided by the present application can make the aroma of Marselan grape wine more rich and sweet, and the variety aroma and aging aroma are tightly integrated, which maximizes the style characteristics of Marselan grape wine, and greatly improves the quality of grape wine.

This utility model relates to the field of winemaking technology and discloses an auxiliary device for winemaking, including a gear volute. A rotating shaft is rotatably connected inside the gear volute. A first bevel gear is fixedly connected to the outer surface of the rotating shaft, and the first bevel gear meshes with a second bevel gear. A first rotating rod is fixedly connected to one end of the rotating shaft, and a second rotating rod is bolted to the other end. A stirring rod is fixedly connected to the outer surfaces of both the first and second rotating rods. A transmission rod is fixedly connected to the end face of the second bevel gear via a shaft. This utility model uses a drive motor to drive the transmission rod, bevel gear, and rotating shaft, causing the rotating rod and stirring rod to rotate. This allows for comprehensive and efficient stirring of the yeast and grains. Adjacent stirring rods are at a 90-degree angle to avoid dead zones and ensure full contact, providing favorable conditions for fermentation. Simultaneously, rolling wheels allow the device to move smoothly on the container surface, facilitating stirring at different locations, improving stirring uniformity, and enhancing the quality and yield of the wine.

The invention discloses non-saccharomyces cerevisiae and application thereof, particularly relates to native hansenula polymorpha NK2 in Uygur autonomous region in Xinjiang and application thereof in wine brewing, and belongs to the technical field of wine brewing and microbial screening. The hansenula polymorpha NK2 locally screened in the Uygur autonomous region of Xinjiang is provided for solving the problems that due to the fact that the global climate is warmed, sugar is accumulated and increased in the grape mature period, the alcohol content of wine is generally high, fragrance such as flower fragrance and fruit fragrance is covered, and taste balance and coordination are damaged. The alcohol content can be reduced and the aroma quality can be improved in wine fermentation.

This utility model relates to the technical field of brewing still devices, and discloses a brewing still device for winemaking, including a double-layer still body. A still lid is provided on the top of the double-layer still body, and a steam vent is opened on the top of the still lid. A rotating shaft is fixedly connected inside the double-layer still body, and multiple openable and closable door panels are rotatably connected to the outer wall of the rotating shaft. Each openable and closable door panel has multiple holes, and a roller is fixedly connected to the bottom of each openable and closable door panel. A base pot is provided at the bottom of the double-layer still body, and a steam pipe and a drain pipe are fixedly connected inside the base pot. One end of the steam pipe extends to the inner wall of the base pot and is fixedly connected to a gas exhaust pipe. In this utility model, through the ingenious linkage design of the rollers and the openable and closable door panels, the automatic loading and rapid unloading of the mash is achieved, effectively solving the technical problems of high labor intensity and low efficiency in the loading and unloading stages of traditional brewing processes.

The invention relates to the technical field of wastewater multi-stage treatment, in particular to wine brewing wastewater carbon source treatment equipment and a sewage treatment method.The wine brewing wastewater carbon source treatment equipment comprises a treatment pond, and a sieve plate is arranged on one side of the treatment pond; a scum grating is arranged in the treatment pond, a supporting rod connected with the pond bottom of the treatment pond is arranged at the bottom of the scum grating, the scum grating is provided with a protruding part extending towards the sieve plate, and a stacking area used for collecting scum is formed at the protruding part; a collecting device is arranged on the treatment pond and is used for collecting the scum gathered in the accumulation area. Through the treatment tank, the scum grating and the collection device, the function of gathering scum in the wine brewing wastewater to efficiently collect the scum is realized, and the effects of avoiding random diffusion of the scum, preventing a sieve plate from being blocked and improving the subsequent treatment efficiency of the wastewater are achieved; the problem that the waste water treatment effect is affected due to the fact that scum is accumulated at the sieve plate in traditional wine brewing waste water treatment equipment is solved.
