Embodiment 1

[0034] A kind of liquor distillation method that reduces fusel oil content comprises the following steps:

[0035] (1) Pump the mature mash into the distillation preheating tank, heat up to 35-50°C and put it into the distillation retort;

[0036] (2) Turn on the direct steam to 0.6MPa until the temperature inside the retort reaches 90°C, turn off the steam to 0.3MPa;

[0037] (3) False wine heads are discharged after the wine is released, and the wine heads are collected when the measured alcohol content reaches 60%;

[0038] (4) After collecting 10% of the volume of base wine A, turn the valve to the base wine tank, and return the direct steam to 0.6MPa; (5) After collecting 90% of the volume of base wine A, turn off the steam;

[0039] Divide the 10% volume base wine A head (58.5% V / V) into two parts, one part is directly mixed with the base wine A body in proportion, and blended to become a control sample.

Abstract

The invention discloses a distilling method for reducing fusel oil in baijiu. The method comprises the steps: firstly, distilling ripe mash at a slow speed under 0.2 to 0.3MPa steam, gathering fusel oil in foreshot and collecting the foreshot; rectifying the foreshot to remove the fusel oil to obtain base liquor. According to the method disclosed by the invention, the fusel oil can be gathered inthe foreshot through slow-speed distillation, so that only 10 to 30% volume foreshot is rectified in a following residue removing procedure, and 70 to 90% volume heart cut is prevented from being treated; thus, a rectifying amount is greatly reduced. as the alcoholic content of the foreshot is higher, enrichment and separation of the fusel oil are facilitated, and a rectifying reflux ratio can bereduced. Comprehensive results are that steam and electricity consumption is saved, a residue removing efficiency is improved, and easiness in production application is achieved.

Description

technical field [0001] The invention belongs to the field of liquor production, and in particular relates to a distillation method for reducing fusel oil in liquor. Background technique [0002] Fusel oil is a mixture of various higher alcohols produced during the production of liquor, and its main components are propanol, isobutanol, amyl alcohol, and isoamyl alcohol. Too much fusel oil in wine will not only cause spicy and bitter taste, but also endanger human health, stimulate and anesthetize the nervous system, and cause a series of symptoms such as headache, dizziness, drowsiness, dry mouth, etc.; Less will make the wine tasteless and lose the original style of traditional liquor. Therefore, the fusel oil content of liquor must be controlled within an appropriate range. At present, the national standard GB / T2757-81 requires the content of fusel oil in liquor to be ≤0.2g / 100mL based on isobutanol and isoamyl alcohol. Reducing the content of fusel oil in liquor is an in...
