Problems solved by technology

However, the process of increasing the concentration of the mash in the process of crushing raw materials (such as increasing the ratio of material to water to 1:2.0 or higher) will encounter practical problems such as increased viscosity of the mash and affecting the transportation of the mash.
In order to solve the above problems, increasing the particle size of starchy raw materials and reducing the water absorption speed of the crushed raw material particles can effectively increase the proportion of free water in the mash, which is an effective way to improve the fluidity of the mash. Liquefaction injection will be difficult to quickly crush and dissolve the large-grain starch in the mash and achieve a good liquefaction effect. There is no report on similar equipment that can effectively solve the problem of liquefaction of large-grain starchy raw materials in the mash

Abstract

The invention provides an injection fragmentation device, which comprises a casing (5), a primary nozzle (6) and a secondary nozzle (3) are arranged on external circumferential wall of the casing, a primary converging-diverging duct (19) arranged between the primary nozzle (6) and the secondary nozzle (3) and on the internal wall of the casing; and a secondary converging-diverging duct (23) arranged at bottom of the casing. In addition, the invention also provides an injection fragmentation method by using the injection fragmentation device. The invention provides the injection fragmentation device and the injection fragmentation method, so that starchiness raw material undecanted wine with granularity greater than 3mm can be fully and effectively fragmented.

Description

technical field [0001] The invention relates to the field of mechanical equipment, more specifically, to a jet breaker and a jet breaker method using the jet breaker. Background technique [0002] At present, the saccharification process of ethanol production usually adopts the production process of medium and low temperature liquefaction injector. The process and characteristics of the process are as follows: the crushed starchy raw material is mixed with the mixing water, and a certain amount of liquefaction enzyme is added to mix evenly Finally, the mash is directly sent into the liquefaction injector through the pump and mixed with primary steam for instant heating. After the mash is heated to the liquefaction temperature, it is sent to the subsequent process for liquefaction and saccharification. Its process features are mainly simple process operation, obvious energy-saving effect, and small equipment footprint. The liquefaction injector used is the main equipment to r...
