Description

Technical Field

[0001] The invention belongs to the technical field of enzymatic preparation, and in particular relates to an enzymatic preparation device and a preparation method for seaweed extract. Background Art

[0002] The existing seaweed enzymolysis generally completes the entire enzymolysis process in a single fermentation tank, and generally multiple required enzymes are added at one time. However, the optimal activity conditions of different types of enzymes are significantly different. For example, the optimal action range of pectinase is usually weakly acidic (pH 4.5-5.5), while the activity conditions of cellulase and alginate lyase are more neutral or weakly alkaline. Due to the use of unified enzymolysis activity conditions, it is difficult to meet these requirements at the same time, resulting in reduced enzymolysis efficiency, which affects the quality and yield of the final product. If multiple required enzymes are added in sequence, since the enzymolysis needs to be performed in stages, it depends on manual batch addition of enzymes and adjustment of parameters. Workers need to run back and forth between different fermentation tanks, which has low operating efficiency. If any operation is missed, it will seriously affect the quality of the enzymolysis product. At the same time, in a single tank system, it is very difficult to achieve precise control of pH, temperature and stirring rate. Even if online monitoring equipment is introduced, the complexity of dynamic regulation may cause operating errors, further affecting the stability of the system, and the accumulation of operating errors may have a negative impact on the quality of the final product. Therefore, based on the above situation, a seaweed enzymatic hydrolysis line equipment which can realize efficient operation of the assembly line at a fixed point has been specially developed for the enzymatic hydrolysis preparation of seaweed extracts.

[0014] The present invention has the following beneficial effects due to the adoption of the above technology.

[0015] 1. The present invention successfully constructs a processing production line specifically for seaweed enzymolysis. By adding enzymes in batches in the production line and setting fixed-point stations, efficient assembly line operation is achieved. This design not only improves production efficiency, but also ensures the controllability and stability of the enzymolysis process. The setting of fixed-point stations makes the function of each station specific, avoiding the problems of uneven mixing and low efficiency that may occur in the traditional pre-mixing process of compound enzymes.

[0016] 2. The present invention adopts a strategy of adding enzymes in batches, and in the multi-stage enzymatic hydrolysis process, each stage can independently optimize the pH value, temperature, stirring speed and enzyme addition amount. That is, this multi-stage optimization strategy can maximize the activity of different enzymes, thereby significantly improving the quality of enzymatic hydrolysis. For example, in different enzymatic hydrolysis stages, the pH value can be selectively adjusted to match the optimal activity range of a specific enzyme, or the enzyme activity can be controlled by adjusting the temperature to avoid enzyme inactivation caused by high temperature.

[0017] 3. The present invention pre-constructs a seaweed component database, which can effectively avoid the adverse effects of too low or too high enzyme additions by adding the corresponding enzymes with higher accuracy. That is, the seaweed component database contains component information of seaweeds of different genera, such as the content and composition of pectin, cellulose, protein, lipids, etc. In the actual production process, the system can automatically retrieve relevant information in the database according to the type of seaweed to be processed, so as to accurately calculate the required enzyme addition amount. This intelligent control method effectively avoids the problem of incomplete enzymolysis or waste of enzyme resources caused by excessive or insufficient enzyme addition. .

[0018] 4. The seaweed enzymatic hydrolysis processing line formed by the present invention can adapt seaweeds of different categories to the same seaweed enzymatic hydrolysis processing line, and can add different enzyme amounts according to the seaweeds of different categories. That is, through the integrated control system, the parameter settings of each station, such as the type of enzyme, addition amount, reaction time, etc., can be flexibly adjusted according to the characteristics and enzymatic hydrolysis requirements of different seaweeds. This modular design enables the production line to quickly adapt to the processing needs of different seaweeds, thereby improving the utilization rate and production efficiency of the equipment.
