Continuous amylase conversion device

Abstract

The invention provides a continuous amylase conversion device, and relates to the technical field of papermaking. The continuous amylase conversion device comprises a pre-mixing mechanism, a low-temperature heater, a heat preservation cabinet, a high-temperature cooking cabinet and a concentration adjusting mechanism, wherein the bottom end of the pre-mixing mechanism is fixedly connected with a discharging pipe, a discharging electromagnetic valve is installed at the end, close to the pre-mixing mechanism, of the discharging pipe, the end, away from the pre-mixing mechanism, of the discharging pipe is fixedly connected with the low-temperature heater, a first control panel is arranged in the center of the outer surface of the front end of the low-temperature heater, and the pre-mixing mechanism comprises a fixed base. According to the invention, by designing the split type premixing mechanism, the low-temperature heater, the heat preservation cabinet, the high-temperature cooking cabinet and the concentration adjusting mechanism, amylase conversion processing can be carried out in batches according to needs, all the mechanisms only need to complete respective work in a short time, and continuous work is not needed in other time, so that the working efficiency is greatly improved while the energy consumption is also reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a continuous amylase converting device. Background technique [0002] Starch is an auxiliary product commonly used in the papermaking industry. It is mostly used in papermaking surface sizing, coating and other aspects. However, due to the poor adhesion of native starch, high gelatinization temperature, poor film forming and transparency, it is difficult to meet the requirements of the papermaking industry. For sizing or coating, in order to improve the application performance of starch, the original properties of starch must be changed by chemical, physical, biological and other methods; the most commonly used starch modification methods in the paper industry are roughly divided into two categories, one mainly Cationic starch and cross-linked starch are prepared by chemical modification methods such as etherification, esterification and cross-linking; the other is rheologica...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a continuous amylase conversion device, which solves the problem that the structural design of the existing equipment is too simple, and in the process of actual use, it is usually necessary to convert one day's papermaking consumption at one time. After the equipment is started, the equipment cannot stop until the production tasks of the day are completed. During the continuous operation of the equipment, it not only consumes a lot of energy, but also the integrated structural design makes the entire equipment unusable when a part of the equipment fails. It will also affect the normal progress of papermaking
