Novel circulating mixing device

Abstract

The invention provides a novel circulating mixing device. The novel circulating mixing device comprises a feed pipe (1), an enzyme adding device (2), an alkali adding device (3), a centrifugal pump (4), a centrifugal pump motor (5), an inlet pipe (6), a discharge pipe (7), a charging pipe (8), a branch pipe (9) and a mixing tank (10), wherein the charging pipe (8) is arranged on the top of the mixing tank (10). The novel circulating mixing device is adopted to achieve rapid circulating mixing; semifluid materials can be mixed evenly completely in 15-30 minutes, the materials react thoroughly, and the yield of products is high.

Description

technical field [0001] The invention relates to mechanical equipment for stirring and mixing non-fluid viscous sol, in particular to a novel circulating mixing device. Background technique [0002] General fluid mixture materials such as starch or corn flour (see Table 1 for fineness), can be mixed evenly in the mechanical mixing tank, the slurry ratio can reach more than 25%, and the normal liquefaction and saccharification reactions are carried out, and the filtration speed is fast to achieve high conversion. rate and yield.

Problems solved by technology

[0005] However, the following light and flexible substances containing starch and fiber with small particle size (see Table 2), light specific gravity, and high water holding capacity are non-fluid thick mash when pulping, and it is difficult to stir with a common mechanical mixing tank. Uniform, so the material reaction speed is slow, and the reaction is not complete, resulting in poor liquefaction of sugar, low catalytic hydrolysis rate, affecting product quality and low material yield
