Continuous operation steam explosion unit

Abstract

The invention discloses a continuous operation steam explosion unit. The invention is used for solving the problems that when steam explosion is conducted on low density and loose materials such as straws, the operation efficiency is low. The continuous operation steam explosion unit is provided, the production rate is improved, the processing difficulty of the light specific gravity raw materialsis solved, under the steam pressure of 2 MPa-3 MPa, the specific gravity of the material is 300 kg / m3 after the material is compressed, pressure maintaining is conducted for 60-90 seconds, instant steam explosion of the straws such as corn, wheat and rice is conducted, and industrial production is realized. The continuous operation steam explosion unit is mainly composed of a feeding distributor,a material conveying pipeline and two or more continuous operation steam explosion machine units, a feeding compression piston moves reciprocally in a feeding steam explosion cylinder, the materialsare compressed and pushed into the steam explosion cylinder, so that continuous feeding and compression are realized; and when the steam explosion machine units are in a pressure maintaining and steamexplosion process, the feeding distributor feeds the next steam explosion machine unit, when the previous steam explosion unit finishes the steam explosion operation and enters feeding operation again, the feeding distributor feeds the steam explosion machine unit again, the whole continuous operation steam explosion unit is fast in operation and high in efficiency.

Description

technical field [0001] The invention belongs to the field of crop straw roughage processing, and in particular relates to a continuously operating steam explosion unit. Background technique [0002] 60% of crop stalks are carbohydrates, which can be used as raw materials for fermentation industry, especially in the feed industry. If these stalks can be converted into feed grains, it will save a lot of food, solve the problem of human and animal competition for food, and also solve the problem caused by straw burning. Environmental Pollution. The direct feeding effect of straw as feed is poor. In order to improve the low nutritional value of feed, people use various means to change its natural structure and enrich nutrition. [0003] The steam explosion technology can realize the change of the natural fiber structure of the straw, and it is easier to realize the fermentation and enzymatic hydrolysis of the straw. The volume is limited, the operation efficiency is low, and i...

Problems solved by technology

[0003] The steam explosion technology can realize the change of the natural fiber structure of the straw, and it is easier to realize the fermentation and enzymatic hydrolysis of the straw. The volume is limited, the operation efficiency is low, and only small-scale production can be carried out. It is not suitable for operations on low-density and loose materials such as straw.
