Problems solved by technology

The high content of methanol makes the product exceed the national standard, which seriously affects the quality of the product and the development and utilization of raw materials. Sometimes the wine with methanol exceeding the standard can only be discarded
Or need follow-up steps and equipment to remove methanol, which increases the production cost of the product
In addition, if blending is carried out to reduce the concentration of methanol in the wine, it will affect the taste of the wine. The alcohol content of ice wine is usually low, and the alcohol content after blending is even lower, which will not meet the basic production requirements.
Although the aging process can also reduce the content of methanol, the long cycle is not conducive to the rapid brewing and production of ice wine industry

Embodiment 1

[0022] Such as figure 1 As shown, an automatic fermentation and detection device for ice wine, the device includes a fermentation tank (1), a surrounding copper tube (2), a control center (3), a display device (4), and a surrounding copper tube (2) is arranged outside the fermentation tank , the copper tube is surrounded by constant temperature cold water, and the fermenter contains a barometer (5), a visual probe (6), an alcohol tester (7), a temperature sensor (8), and a pH meter (9), wherein the barometer ( 5), the visual probe (6) is arranged in the upper part of the tank body, and the alcohol tester (7), the temperature sensor (8), and the pH meter (9) are arranged in the lower part of the tank body. The visual probe (6), the alcohol tester (7), the temperature sensor (8), and the pH meter (9) are connected to the control center, and the control center is connected to the display center, and corresponding indicators are displayed from the display center. In addition, the...

Embodiment 2

[0026] The present invention also provides a method for producing ice wine by using the ice wine automatic fermentation and detection device, the specific steps are (1) cleaning, crushing and beating; (2) pectinase treatment; (3) sulfur dioxide treatment; (4) adjusting pH and sugar content; (5) adding yeast into the tank for low-temperature fermentation; (6) clarification and filling. No aging required.

[0027] The applicant repeated the fermentation 10 times with the same fermentation conditions each time to obtain 10 samples of ice wine. The methanol content of the obtained ice wine was all <200 mg / L, and the average methanol content was 142 mg / L.

[0028] As a contrast, using the same raw materials, the same production fermentation conditions, the same fermentation equipment, only the control system is closed, among the 10 ice wine control samples, one sample of the obtained ice wine reached 274mg / L, and the average methanol content was 184mg / L.

[0029] It can be seen t...

Abstract

The invention relates to a device for automatically fermenting and detecting ice wine, and a method for brewing ice wine by using the device. The device comprises a fermentation tank (1), a surrounding copper pipe (2), a control center (3) and a display device (4), wherein the surrounding copper pipe (2) is arranged outside the fermentation tank and is internally filled with constant temperature cold water; the fermentation tank is internally provided with an air pressure gauge (5), a visual probe (6), an alcohol content tester (7), a temperature sensor (8) and a pH meter (9). The corresponding parameters of fermentation liquor and the fermentation tank are set by means of the control center, so that the methyl alcohol content of the ice wine is enabled to be less than 200mg / L.

Description

technical field [0001] The invention relates to a wine fermentation and detection device and an ice wine brewing method, in particular to an ice wine automatic fermentation and detection device and an ice wine brewing method. Background technique [0002] Ice wine (Ice wine) refers to: delaying the harvest of grapes, keeping the grapes on the branches for a certain period of time when the temperature is lower than -7°C under natural conditions, freezing, harvesting, pressing in the frozen state, and fermenting The resulting wine (additional sugar sources are not allowed in the production process). In order to ensure the quality, ice grapes are often harvested in the middle of the night and stopped before the sun comes up in the morning. Because the water in the grapes has frozen, the grape juice squeezed out at this time only leaves the sugar and other nutrients in the grapes. We call such grape juice grape honeydew. Ice wine is brewed from such grape honeydew. Generally ...
