Abstract

The present invention relates to agricultural production, a kind of method that utilization energy grass prepares fermentation grass juice factor and paper pulp is disclosed, fermentation grass juice factor and paper pulp are efficiently produced using energy grass as raw material.The present invention separates the grass juice factor of energy grass and careless slag by the method for mechanical expression, and grass juice factor efficiently produces fermentation grass juice factor by microbial fermentation, and careless slag produces paper pulp by ultrasonic assistant biological enzyme.The present invention realizes the efficient of energy grass, multidirectionalization purposes, and new direction is provided for the comprehensive utilization of energy grass.

Description

A kind of method that utilization energy grass prepares fermentation grass juice factor and paper pulp

Technical field

The invention belongs to agricultural production system field, and in particular to a kind of utilization energy grass preparation fermentation grass juice factor and paper pulp Method.

Background technology

Energy grass means a class based on grass, annual or perennial, high yield, high cellulose content Energy-source plant.It is widely used in field of biological energy source, but not yet forms complete, rational system, therefore energy grass Value does not maximize the use.

Paper pulp is using string as raw material, through fibrous material made from different processing methods.Can be according to processing method It is divided into mechanical pulp, chemical pulp and chemimechanical pulp, it is the base stock of papermaking.Generally it is used to the plant of pulping raw material 4 major classes can be divided into：Stem fiber-like, bast fiber class, seed hair fiber class and lumber fibre class, wherein especially using lumber fibre class as It is most important.The need for current China's timber resources is far from growing pulp and paper industry is met.In order to make up raw material Deficiency, the paper pulp needed for annual China there are about 40% needs from external import.

Fermentation grass juice factor is that the one kind produced after grass juice factor undergoes microbial fermentation can produce feed or therefrom isolate L- breasts The Fermentation Engineering product of acid.

The content of the invention

Object of the present invention is to provide a kind of method that utilization energy grass prepares fermentation grass juice factor and paper pulp, energy is being utilized Source grass production fermentation grass juice factor while also produce paper pulp, widened the utilization scope of energy grass, constructed one it is multi-direction comprehensive Close the system using energy grass.

To achieve the above object, the present invention is adopted the following technical scheme that：

A kind of method that utilization energy grass prepares fermentation grass juice factor and paper pulp, production fermentation grass juice factor and paper pulp by raw material of energy grass, Comprise the following steps：

1) fresh energy grass is first ground into 0.1 ~ 5cm, grass juice factor and careless slag is then separated into by mechanical expression；

2) energy grass grass juice factor prepares fermentation grass juice factor：By step 1) in obtained grass juice factor undergo microbial fermentation 2-7 days, hair is made Ferment grass juice factor, fermentation grass juice factor can be processed as feed or feed addictive, can also therefrom isolate Pfansteihl；

3) carelessly slag prepares paper pulp to the energy：Take step 1) in the isolated further removal of impurities of careless slag, crush after, in ultrasonic wave Water, mixed enzyme are added in reactor, mixing enzyme concentration is 1 ~ 100mg/g, 10 ~ 100khz of ultrasonic frequency, first at 40 ~ 70 DEG C At a temperature of after 1 ~ 5h of reaction, be warming up to 90 ~ 120 DEG C and react 1 ~ 5h again, then by defibrination, washing, screen and dehydration obtains paper Slurry；

Wherein, described energy grass include for Pennisetum plant, Sorghum propinquum, sugar grass, giantreed, reed, class reed, spot thatch, that In special grass, sudangrass, Caulis Miscanthis floriduli, reed, awns, Arundinella hirta (Thunb.) Tanaka, Plantula Neyraudiae Reynaudianae, silage corn, lemongrass, Spartina alterniflora, Value of Spartina Anglica, switchgrass One or more;

The present invention remarkable advantage be：There is provided a variety of utilization orientations of energy grass, hair is being prepared using the fermentation of energy grass juice factor On the basis of ferment grass juice factor, while producing paper pulp, a kind of system of agriculturally comprehensive energy utilization grass is formed.The present invention can be efficient Ground utilize energy grass, the efficiency that grass juice factor individually ferments, which is higher than, directly utilizes energy grass fermentation.Overall process no pollution of the present invention, The product of any pollution environment will not be produced.The present invention has prominent novelty and practical value.

Embodiment

Embodiment 1

Below with 10 tons of Jujun grasses（Pennisetum plant, dry matter content 25%）The specific of the present invention is expanded on further for example Embodiment, the present invention includes but is not limited to following instance.

（1）Fresh Jujun grasses are first ground into 2cm, 7 tons of grass juice factors and 2.8 tons of grass are then obtained by mechanical expression separation Slag；

（2）It is prepared by the grass juice factor that ferments：By step 1) in obtained grass juice factor undergo microbial fermentation 5 days fermentation grass juice factor, Fermented Grass be made Juice can be processed as feed；

（3）Careless slag prepares paper pulp：Take step 1) in the isolated further removal of impurities of careless slag, crush after, in ultrasonic response kettle Middle addition water, mixed enzyme etc., mixing enzyme concentration are 20mg/g, ultrasonic frequency 60khz, first after reaction 3h at a temperature of 60 DEG C, 120 DEG C of reaction 1h are warming up to, then paper pulp is obtained by defibrination, washing, screening and dehydration etc.；

7 tons of fermentation grass juice factors can be produced using 10 tons of Jujun grasses of dry matter content 25% of the invention, are done while 2 tons can be produced The paper pulp of material.Production efficiency is substantially increased, the economic worth of Jujun grasses is improved.

Embodiment 2

Below with 10 tons of sugar grasses（Dry matter content 30%）The embodiment of the present invention, this hair are expanded on further for example It is bright to include but is not limited to following instance.

（1）Fresh sugar grass is first ground into 3cm, 6 tons of grass juice factors and 3.8 tons of careless slags are then obtained by mechanical expression separation

（2）It is prepared by the grass juice factor that ferments：By step 1) in obtained grass juice factor undergo microbial fermentation 4 days fermentation grass juice factor, Fermented Grass be made Juice can be processed as feed；

（3）Careless slag prepares paper pulp：Take step 1) in the isolated further removal of impurities of careless slag, crush after, in ultrasonic response kettle Middle addition water, mixed enzyme etc., mixing enzyme concentration are 30mg/g, ultrasonic frequency 40khz, first after reaction 2h at a temperature of 55 DEG C, 110 DEG C of reaction 2h are warming up to, then paper pulp is obtained by defibrination, washing, screening and dehydration etc.；

6 tons of fermentation grass juice factors can be produced using 10 tons of sugar grasses of dry matter content 30% of the invention, while 2.5 tons can be produced The paper pulp of dry.Production efficiency is substantially increased, the economic worth of sugar grass is improved.
