Problems solved by technology

[0002] Existing alcohol fermentation tanks are usually vertical tanks. With the development of alcohol fermentation technology, in continuous fermentation technology, especially in large-scale continuous fermentation technology, multiple fermentation tanks connected in series will be used. Each fermentation tank It is necessary to connect the upstream and downstream fermentation tanks with connecting pipes, and each connecting pipe needs to have at least two valves for process control, which requires a large investment in equipment and many dead ends in the pipeline; The material in the tank is prone to stagnation and slip flow, which affects the efficiency of fermentation. In order to solve this problem, in the existing technology, 2 to 3 side agitators are often installed for each fermentation tank, which requires Increase the equipment investment and power consumption of the mixer, and increase the chance of being polluted by impurities due to the addition of openings on the fermentation tank

Embodiment 1

[0025] Embodiment 1: as attached figure 1 As shown, corn is used as raw material, whole-grain dry crushing process is adopted, and the scale of a fermentation workshop with an annual output of 50,000 tons of alcohol is taken as an example: a horizontal clapboard alcohol fermentation tank, the shape of the vertical section of the tank body 1 is circular, and the diameter is φ16000mm , the total length is 26000mm, and its axial ends are respectively provided with material inlet 2 and material outlet 3, and the tank body 1 is vertically arranged with seven partitions 4 in the radial direction, which can divide the tank body into eight intervals 5. The upper or lower part of the plate 4 is provided with gaps 6 communicating with the intervals 5 on both sides of the partition 1, the gaps 6 on two adjacent partitions 4 are staggered up and down, and the intervals 5 in the tank body 1 communicate through each gap in turn, which is equivalent to Eight fermenters connected in series of...

Embodiment 2

[0042] Embodiment 2: as attached figure 2As shown, taking cornstarch milk as raw material and a fermentation workshop with an annual output of 100,000 tons of alcohol as an example, the horizontal clapboard alcohol fermentation tank, the vertical cross-section of the tank body 1 is circular, the diameter is φ16000mm, and the total length is 52000mm , its axial ends are respectively provided with a material inlet 2 and a material outlet 3, and seven partitions 4 are arranged vertically in the radial direction of the tank body 1, which can divide the tank body into eight intervals 5. The gaps 6 that communicate with the gaps 5 on both sides of the partition 1, the gaps 6 on the two adjacent partitions 4 are staggered up and down, and the gaps 5 in the tank body 1 are connected sequentially through the gaps, which is equivalent to eight in the prior art. Fermentation tanks connected in series.

[0043] The lower part of the partition 4 with the notch 6 on the upper part is also...

Abstract

The present invention discloses a horizontal partition alcoholic fermentation tank. It includes a tank body, and said tank body is characterized by that the vertical radial length of said tank body is less than its horizontal axial length, its axial two ends are respectively equipped with material inlet and material outlet, in the tank body interior at least one partition is radially vertically placed, said partition can be used for dividing tank body interior into two compartments, the upper portion or lower portion of said partition is equipped with a notch for making said two comportments be communicated each other.

Description

technical field [0001] The invention belongs to the technical field of continuous fermentation engineering for alcohol production, and in particular relates to an anaerobic fermentation tank. Background technique [0002] Existing alcohol fermentation tanks are usually vertical tanks.
