Natural faric hydrolysis reactor

Abstract

The invention relates to a natural fiber hydrolytic reactor, which at least comprises an extruder charging barrel device, a power-driven device and a gas-liquid separation tank device, wherein the inside of the extruder charging barrel device is provided with a feeding compression screw, and the extruder charging barrel device is provided with a temperature control device and provided with a first feed opening and a first discharge opening; the power-driven device is connected with the feeding compression screw and drives the feeding compression screw to rotate; and the gas-liquid separation tank device is provided with a second feed opening and a second discharge opening, and the second feed opening is connected with the first discharge opening of the extruder charging barrel device. Starch or raw materials which are mixed with plant cellulose and hemicellulose are placed into the natural fiber hydrolytic reactor, and subjected to plasticizing, supercharging and heating of the natural fiber hydrolytic reactor to initiate hydrolysis, so as to prepare a sugar solution. The natural fiber hydrolytic reactor can prepare the resultant - the sugar solution by utilization of the natural starch or the raw materials which are mixed with the plant cellulose and the hemicellulose and without any additive, has an environment-friendly processing procedure, can not cause environmental burden, and has the efficacies of simple and easily controlled processing procedure, reduction of the manufacturing cost and so on.

Description

technical field [0001] The invention relates to a saccharification and hydrolysis process equipment, in particular to a natural fiber hydrolysis reactor with an extruder barrel device for plasticizing pressurization and without additional additives. Background technique [0002] my country's dependence on imported energy is getting higher and higher, and international oil prices continue to rise. If bio-alcohol can be used to reduce the use of oil, it is an important policy that involves the country's overall strategic significance. Bio-alcohol can effectively reduce greenhouse gases and The emission of air pollutants can also improve the performance of vehicles, and it is one of the important renewable and environmentally friendly fuels to replace fossil fuels. Alcohol produced by fermenting sugar liquid as a raw material is a fairly mature technology, and it has been developed in Brazil for more than 30 years, and has become an object that the world is eager to emulate.

Problems solved by technology

The acid hydrolysis rate is high and the operation is easy, but due to the lack of specificity of the acid hydrolysis and the steps of neutralization treatment, separation and purification after the reaction, a large amount of waste liquid is generated, which increases additional costs and the burden on the environment

Ultrasonic hydrolysis is limited by the fact that the hydrolysis rate will decrease with the increase of processing time, and there is a limit on the minimum hydrolyzable molecular weight, and the process control is complicated

Using enzymes to hydrolyze hemicellulose can not only be carried out under normal temperature and pressure, but also has high specificity and is not limited to molecular size, and can produce specific polymerization degree or functional oligosaccharide products by controlling the hydrolysis conditions, but the enzyme The activity and product properties are easily affected by the composition of hemicellulose, the pH of the reaction solution, temperature and liquid volume, or other coexisting substances. Additional enzymes must be added, and the process control is complicated.

[0005] However, the prior art has unavoidable disadvantages, such as the need to use additives, complicated manufacturing process, difficult process control, environmental burden and high manufacturing cost.

[0006] This shows that above-mentioned existing mode of hydrolyzing cellulose obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above-mentioned problems. Urgent problem
