Embodiment 1

[0024] Embodiment 1, a kind of production technology of alcohol, comprises the steps:

[0025] 1) Acceptance of raw materials: choose potatoes with relatively complete roots, uniform size, and about 30% starch content as raw materials, wash them with water and set aside.

[0026] 2) Impurity removal of raw materials: The raw materials washed with clean water are transported to the impurity remover by a belt conveyor to remove impurities such as sediment, stones and metals in raw potatoes.

[0027] 3) Raw material crushing: After removing impurities, the raw material is weighed and transported to the axial drum type coarse crushing by the belt conveyor for coarse crushing. The coarse crushed material is then sent to the hammer mill for fine crushing to obtain raw material powder.

[0028] 4) Precooking and puffing: the raw material powder is adjusted to a wort concentration of 10g / ml with water at a ratio of 1:3, heated to 50°C with steam under normal pressure, and amylase is a...

Embodiment 2

[0035] 1) Acceptance of raw materials: choose potatoes with relatively complete roots, uniform size, and about 35% starch content as raw materials, wash them with clean water and set aside.

[0036] 2) Impurity removal of raw materials: The raw materials washed with clean water are transported to the impurity remover by a belt conveyor to remove impurities such as sediment, stones and metals in raw potatoes.

[0037] 3) Raw material crushing: After removing impurities, the raw material is weighed and transported to the axial drum type coarse crusher for coarse crushing through the belt conveyor. The coarsely crushed material is then sent to the hammer mill for coarse crushing to obtain raw material powder.

[0038] 4) Precooking and puffing: adjust the raw material powder with water to a wort concentration of 12g / ml at a ratio of 1:3 to the ratio of material to liquid, heat it to 55°C with steam under normal pressure, add amylase, and precook for 25 minutes.

Embodiment 3

[0045] 1) Acceptance of raw materials: choose potatoes with relatively complete roots, uniform size, and about 40% starch content as raw materials, wash them with clean water and set aside.

[0046] 2) Impurity removal of raw materials: The raw materials washed with clean water are transported to the impurity remover by a belt conveyor to remove impurities such as sediment, stones and metals in raw potatoes.

[0047] 3) Raw material crushing: After removing impurities, the raw material is weighed and transported to the axial drum type coarse crushing by the belt conveyor for coarse crushing. The coarse crushed material is then sent to the hammer mill for fine crushing to obtain raw material powder.

[0048] 4) Precooking and puffing: adjust the raw material powder with water at a ratio of 1:3 to the wort concentration of 14g / ml, heat to 60°C with steam under normal pressure, add amylase, and precook for 25 minutes.

[0049] 5) Cooking and gelatinization: adopt the low-pressure...

Abstract

The invention discloses an alcohol production process, and belongs to the technical field of alcohol production by a fermentation method. The alcohol production process includes the steps of 1) raw material acceptance: selecting potatoes with complete root blocks and uniform sizes as raw materials; 2) raw material purification: removing impurities such as silt, stones and metal in the potatoes by an impurity remover; 3) raw material crushing: crushing the raw materials by a crusher to obtain raw material powder; 4) precooking and puffing: adding amylase according to a fixed feed liquid ratio and precooking the raw materials in a precooking pot; 5) cooking gelatinization: adjusting a PH (potential of hydrogen) value, adding amylase and cooking the raw materials in a cooker; 6) saccharification: saccharifying the raw materials in a saccharifying tank containing blended orange water; 7) fermentation; 8) distillation; and 9) cooling. The alcohol production process is mature, energy-saving, environment-friendly, simple to operate, applicable to industry, food and the like, and has a quite high economic value, and produced alcohol is high in concentration.

Description

technical field [0001] The invention relates to a production process, in particular to an alcohol production process. Background technique [0002] So far, from the perspective of production methods, the vast majority of alcohol products (more than 90%) in the world are produced by fermentation. Its ingredients come from a wide variety of sources: grains, molasses, fruit juices, wine, whey, cellulose, and other ingredients. Wherein, the alcohol production that uses molasses as raw material production is bigger, accounts for about 45% of the world's total alcohol production, such as Brazil, Pakistan, Australia and other countries all adopt molasses as raw material to produce alcohol. The proportion of alcohol produced by fermentation using starchy raw materials is small, accounting for only about 16% of the world's total alcohol production. In addition, in some countries with rich forest resources and developed paper industry, such as Sweden, Norway, Finland, Austria, Canad...
