Description

Porphyra unwinding flotation device and unwinding process

technical field

The invention relates to a laver processing device and process, in particular to a laver unwinding flotation device and unwinding process.

Background technique

Porphyra is a general term for alternate algae in the sea. Rhodophyceae, Rubiaceae. The algae are membranous and called thallus. Purple or brownish green. Shape varies with species. Porphyra is a marine red algae . The fronds consist of a layer of cells embedded in a thin layer of gelatin and are dark brown, red, or purple. Porphyra holder disk-shaped, rhizome filamentous. Grows on shallow intertidal rocks. There are many kinds, mainly including striped laver, altar laver, sweet laver and so on. Artificial cultivation has been carried out in coastal areas of China. At the beginning of the 21st century, China's seaweed production ranked first in the world. Rich in protein and iodine, phosphorus, calcium and so on. For food and medicine.

Porphyra is simple in shape and consists of three parts: disc-shaped holder, handle and leaves. The leaf is a single or branched membranous body composed of 1 layer of cells (a few species have 2 or 3 layers), and its body length varies from several centimeters to several meters depending on the species.

After cleaning the seaweed collected from the sea, the laver leaves kneaded into the water should be sorted, and the laver leaves with larger leaves and harder taste should be separated from the laver leaves with smaller leaves and softer taste.

detailed description

The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

As shown in Fig. 1 and Fig. 2, a kind of seaweed unwinding flotation device comprises: an airflow unwinding pool 1 arranged obliquely downwards successively, at least one silk screen flotation pool 6 and a strainer draining pool 10, a plurality of The wire sieve flotation tanks 6 are also installed in an inclined downward direction. The middle part of the air flow unwinding tank is divided into an upper part 3 and a lower part 4 by a grid. Controlled by the switch device, the discharge channel 13 is connected to the wire screen flotation cell 6 .

The seaweed slurry can flow through the airflow unwinding pool 1, multiple wire sieve flotation pools 6 and the filter screen draining pool 10 successively, and the airflow gushing through the airflow unwinding pool 1 drives the water to flow, and the laver leaves that are grouped together are untied and evenly distributed. The distribution in the water, the tiny air bubbles attached to the laver leaves, the laver also floats up, passes through the grid 2, reaches the upper part 3, and flows into the first silk screen flotation tank 6; the silk thread 8 of the silk screen 7 can be passed through the silk screen 7 In the process of moving up and down, the laver leaves are hung on the silk thread 8, and the laver leaves are hanged successively, and finally enter the strainer drain pool 10 and all tiny laver leaves are filtered through a relatively dense filter screen 11. The above-mentioned silk screens 7 with different arrangement densities of silk threads 8 screen laver leaves of different leaf sizes to finally obtain laver leaves with the smallest leaves, thereby realizing the process of classifying laver flotation.

The average length of the laver leaves screened out by the silk sieve 7 in each process will be greater than the average length of the laver leaves screened out in the flotation tank 6 of the last silk screen, realizing the process of step-by-step flotation.

One end of silk thread 8 is fixed on the frame body 9, and the other end is detachably fixed on the frame body 9. This structure is conducive to the laver hanging on the thread thread 8 breaking away from the thread thread 8 and reentering the water to mix.

A plurality of wire sieve flotation tanks 6 and filter screen draining tanks 10, which are arranged obliquely downward in turn, are connected through a discharge channel 13, and the discharge channel 13 is controlled by a gate switch, and a drainage channel is provided at the bottom of the filter screen draining tank 10 14. A filter screen 11 is provided in the filter screen drain pool 10 .

A kind of unwinding process using laver unwinding flotation device, comprises the following steps:

(1) Pour the seaweed balls and water into the lower part 4, release the seaweed balls through the air flow, and a single seaweed leaf can enter the upper part 3 through the grille;

(2) When the concentration of laver leaves in the upper part 3 reaches the requirement, pour the laver solution into the adjacent silk sieve flotation tank 6, move up and down through the silk sieve 7, so that the laver is also hung on the silk thread 8, and then sequentially The slurry is introduced into other silk screen flotation cells 6 one by one and floated by silk screen 7;

(3) Finally, the laver slurry is introduced into the filter screen drain pool 10 , the laver in the remaining laver slurry is filtered by the filter screen 11 , and the water is discharged through the drainage channel 14 .
