Steam injection device

Abstract

The invention provides a steam injection device, and mainly relates to the technical field of fructose production and processing. A steam injection device comprises a liquefying tank, a vertical pipe is installed on the inner wall of the top face of the liquefying tank, the bottom end of the vertical pipe is rotationally provided with a hollow connecting disc through a bearing and communicated with the interior of the connecting disc, a first air injection pipe is installed on the bottom face of the connecting disc, and the top end of the first air injection pipe is communicated with the interior of the connecting disc. Strip-shaped grooves are formed in the inner walls of the two sides of the first air spraying pipe correspondingly, and a guide rod is installed in each strip-shaped groove. The device has the beneficial effects that the device is simple in structure and convenient to operate, liquefaction and evaporation can be carried out at the same time, the technological process is shortened, the cost is saved, steam can be recycled and reused, raw steam is saved, waste steam is recycled, secondary jet liquefaction is adopted for liquefaction, the liquefaction and saccharification quality can be improved, raw steam is not wasted, and the energy consumption is reduced. the liquefaction effect is good.

Description

technical field [0001] The invention mainly relates to the technical field of fructose production and processing, in particular to a steam injection device. Background technique [0002] The starch milk section adopts the wet corn production process of "one immersion, two grinding, and three separations". The total product dry matter yield is ≥99%, and the corn starch yield is ≥70%. The sugar making process adopts double enzymatic liquefaction, liquefaction and evaporation They are two key sections of starch sugar production. In the traditional process, these two sections are independent of each other, which not only increases the process flow, but also increases the production time, and the production cost is high, and the steam is directly discharged, which wastes resources and further increases The cost brings inconvenience to fructose production. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a st...
