Embodiment 1

[0041] A method for producing whiskey with waste yeast in the beer production process, comprising the following steps:

[0042] (1) Collection and treatment of waste beer yeast sludge:

[0043] Collect the yeast sludge produced in the beer fermentation process from the beer with an alcohol content above 4%, use a small beer fermentation tank as a temporary storage tank, and directly connect the bottom valve with the bottom valve of the temporary storage tank when the fermentation tank discharges yeast, before operation Connecting pipes, staging tanks, and valves should be sterilized. To prevent the contamination of miscellaneous bacteria, miscellaneous bacteria will increase the bad flavor in beer. The collected yeast sludge is put into a temporary storage tank at 3°C ​​for temporary storage. The collected yeast sludge is filtered through a cross-flow filter to remove waste yeast. Cross-flow The filter element of the filter has a filter diameter of 0.6-0.9 μm and a filtration a...

Embodiment 2

[0048] A method for producing whiskey with waste yeast in the beer production process, comprising the following steps:

[0049] (1) Collection and treatment of waste beer yeast sludge:

[0050] Collect the yeast sludge produced in the beer fermentation process from the beer fermented below 5% alcohol content, use a small beer fermentation tank as a temporary storage tank, and directly connect the bottom valve with the bottom valve of the temporary storage tank when the fermentation tank discharges yeast, before operation Connecting pipes, staging tanks, and valves should be sterilized. To prevent the contamination of miscellaneous bacteria, miscellaneous bacteria will increase the bad flavor in the beer. The collected yeast sludge is put into a temporary storage tank at 5°C for temporary storage. The collected yeast sludge is filtered by a centrifugal filter to remove yeast. The rotational speed of the centrifugal filter It is 3000r / min, and the centrifugation time is 15min, ...

Embodiment 3

[0056] A method for producing whiskey with waste yeast in the beer production process as described in Example 1, the difference is:

[0057] In step (3), the semi-finished product obtained in step (2) is aged with deep-roasted oak chips: take deep-roasted oak chips and put them into a stainless steel fermenter to seal. The dosage is: add 1 g of deep-roasted oak chips per liter of whiskey, Aging time of 2 months at 13°C.

Abstract

The invention relates to a method of utilizing waste yeast from a beer production process to produce whiskey. The method comprises the following steps: collecting and filtering beer yeast slurry, utilizing a distillation manner combining primary distillation and secondary distillation, adopting moderately or mildly roasted oak chips to age the alcohol. The prepared whiskey is harmonious in the body, has the oak smoky flavor and the scent of aldehyde, as well as a faint scent taste of light beer; the smoky flavor of the oak is blended in the wine body; the prepared whiskey is crystal clear in the color, dry and strong in taste, thick, and strong in the flavor; the wine body is thick and harmonious; the flavor of the wine is strong and pure; the method can achieve a higher economic additional value.

Description

technical field [0001] The invention relates to a method for producing whiskey by using waste yeast produced in the beer production process, belonging to a distilled wine technology. Background technique [0002] Yeast slime is a mixture of yeast cells and beer liquid produced during beer fermentation, and its content accounts for 1.5-2% of the total amount of beer. It is usually a recyclable resource in production, but only two parts are usually recycled in breweries. Three generations of yeast, and only 40-50% of the yeast sludge is recycled, and the remaining 50-60% of the yeast is discarded. my country is a big beer production country. In 2013, China's beer production was 50.61 million tons. It is estimated that the discarded yeast There are as many as 500,000 to 600,000 tons of mud. [0003] Yeast slime is rich in nutrients. Yeast slime mainly includes deep processing and rough processing. Deep processing refers to the extraction and purification of single components of ...
