Problems solved by technology

But there are still the following problems: 1. The production process is to obtain the product by distributing and distilling in the retort barrel. Due to the intermittent operation of the process, the composition and flow rate of the distilled product change with time, resulting in low production capacity, high energy consumption, and unstable product quality. The labor intensity of production workers is high, the operating environment is poor, and alcohol gas and sewage cause environmental pollution; 2. The product yield is low, generally the yield of ethanol is about 90%, and the yield of aroma components is about 10%; 3. The yield of finished products is low, and the yield of wine The process cuts the head and removes the tail to reduce the quantity of finished wine; 4. High energy consumption, the cooked wine grains contain about 70% water, the temperature is about 120°C, the energy cannot be recovered, and it must be cooled before reuse; 5. Discharge of distillation waste water pollutes the environment
Patent 202898393U provides a high-efficiency distiller for solid-liquid fermentation, which integrates the distillation part and the condensation part, and realizes continuous feeding and discharging at the same time, but this equipment can only realize continuous distillation of fermentation liquid, but cannot complete solid Continuous distillation of fermented grains

Embodiment 1

[0020] The liquor production of a certain wine company adopts the old five retort fermentation process. In this example, the fermented fermented grain obtained by the last retort is used as the raw material, and the device for producing liquor by continuously distilling the solid fermented fermented grain of the present invention is used to produce liquor. The raw material components of the fermented grains are 3.15% ethanol, 56% water, and the rest are solids. The device used is a cylindrical distillation column with a diameter of 0.6 m and a height of 4 m. The solid fermented grains with a temperature of about 30°C are fed at a rate of about 1200kg per hour, the top loosener rotates at 45rpm, and the steam used is 0.2Mpa (gauge pressure), when the height of the upper distillation bed in the tower reaches about 1.5m , open the power rotating device 16, the redistributor 9 and the unloader 10 start to rotate, when the speed of the unloader is adjusted to be about 2.2rpm, the h...

Embodiment 2

[0022]Under the condition of embodiment 1, after 5 hours of smooth operation, the edible alcohol that concentration is 94.5% is vaporized in vaporizer, and is introduced into bed through wine gas inlet 8, and the flow of wine gas is 9.5kg / h, and the bed after two hours Stable, the operating conditions are the bed height: the upper distillation bed is 1.5m, the lower distillation bed is 0.8m; the temperature at the top of the bed is 82°C, the temperature in the middle is 85°C, and the temperature at the discharger is 123°C; the product flow rate is 52.6kg / h , the product sample was analyzed by gas chromatography and the composition was as follows: the mass content of ethanol was 68.21%, water 23.15%, acetaldehyde 0.05%, methanol 0.02%, ethyl acetate 0.22%, isoamyl alcohol 0.11%, ethyl lactate 0.16%; ethanol The content is greatly increased, and the extraction rate of aroma components is increased. Due to the addition of steamed liquor in the tower, the extraction rate of aroma ...

Embodiment 3

[0024] In this example, the fermented glutinous rice grains obtained in the fourth retort are used as raw materials, and the same device described in the above example of the present invention is used to carry out the distillation of fermented glutinous rice grains to produce liquor. The raw material components of the fermented grains are 7.2% ethanol, 58.6% water, and the rest are solids. The solid fermented grains with a temperature of about 42°C are fed at a rate of about 900kg per hour after the bran is mixed, the top loosener rotating speed is 45rpm, and the steam used is 0.2Mpa (gauge pressure). When the height of the distillation bed in the tower reaches 1.5 When it is about m, the power rotating device 16 is turned on, and the redistributor 9 and the unloader 10 start to rotate. When the speed of the unloader is adjusted to be about 2.2 rpm, the height of the upper distillation bed can be controlled at about 1.5 m, and the height of the lower distillation bed can be con...

Abstract

The invention relates to a continuous distillation device for solid fermented grains in the liquor production process. The device is a cylinder-shaped or circular truncated cone-shaped distillation tower shell on the whole; the top and the bottom of a distillation tower are respectively connected with a rotating device; a solid fermented grain feeding hole 3 and a distilled liquor steam outlet 2 are formed in the outer side of the top of the distillation tower shell; a fermented grain loosening transmission device 4 and a distribution device 5 are arranged on the top of the distillation tower; a redistributor 9 and a cross steaming stream inlet 8 are arranged in the middle of the distillation tower; the lower part of the distillation tower is provided with a solid material unloader 10, a material collecting plate 13, an unloading hole 15 and a heating steam inlet 11; an upper layer steam, liquid and solid three-phase heat transfer and mass transfer distillation bed layer is formed between the fermented grain loosening transmission device 4 and the redistributor 9; and a lower layer steam, liquid and solid three-phase heat transfer and mass transfer distillation bed layer is formed between the redistributor 9 and the solid material unloader 10. The continuous distillation device not only can realize high-efficiency and high-yield automatic production with stable quality, but also realizes the cross steaming operation of the liquor production, thus greatly improving the liquor production capability of the solid fermented grains; and furthermore, the device has the advantages of alleviating pollution, saving energy, reducing consumption, etc.

Description

Technical field [0001] The present invention is the field of food engineering technology, which involves the device for solid fermentation wine distillation of liquor production process.
