Description

Technical Field

[0001] The utility model relates to the field of brown algae oligosaccharide production, in particular to a brown algae oligosaccharide enzymatic hydrolyzate filtering mechanism. Background Art

[0002] Brown algae oligosaccharide is a light yellow-brown powder that is soluble in water and has a strong structural stability. Therefore, it is used in various fields of life, such as: medicine (with blood sugar lowering, anti-inflammatory, immune regulation and other effects), food (as a food additive to improve food texture and taste), agriculture (as a plant growth regulator to promote plant growth and enhance crop resistance) and feed (used in animal feed to improve animal immunity and growth performance). Its preparation process includes raw material mixing, enzymatic hydrolysis and filtration, among which filtration includes centrifugation of the enzymatic hydrolyzate, filtration of the enzymatic hydrolyzate and air drying of the filtrate, among which centrifugation and filtration of the enzymatic hydrolyzate are the most important parts.

[0003] The existing filtration mechanism for the hydrolyzate of brown algae oligosaccharides consists of a centrifuge, an ultrafiltration membrane filter, and an air dryer. After the centrifuge separates the hydrolyzate into solid and liquid, the centrifuged hydrolyzate is placed on the ultrafiltration membrane filter in the filter box for secondary filtration (under a certain pressure, the ultrafiltration membrane allows small molecular solutes and solvents to pass through the membrane pores, while large molecular solutes are retained on one side of the membrane, thereby achieving the purpose of separation, purification, and concentration).

[0004] Although existing brown algae oligosaccharide hydrolysate filtration mechanisms can filter and purify the hydrolysate through ultrafiltration membranes, most ultrafiltration membranes are directly laid in the corresponding filter box, generally in a single layer. This laying method allows the hydrolysate to have a larger rated contact area during filtration. However, when too much hydrolysate is added, uneven filtration will occur. The ultrafiltration membrane on the bottom surface will gradually become clogged over time, and there is only one contact surface on the bottom surface. This makes it slower when facing thicker hydrolysate. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing brown algae oligosaccharide enzymatic hydrolysate filtering mechanism mostly filters and purifies the enzymatic hydrolysate through a single-layer ultrafiltration membrane, which makes it difficult to quickly filter a large amount of enzymatic hydrolysate.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a brown algae oligosaccharide enzymatic hydrolyzate filtration mechanism, including a filter box, an ultrafiltration membrane is provided inside the filter box, a plurality of filter tubes are provided inside the filter box, an interlayer plate for fixing the filter tubes is provided inside the filter box, a plurality of liquid grooves are provided on the side walls of the filter tubes, the ultrafiltration membrane is wrapped around the outer wall of the filter tube, and a conical liquid outlet is provided on the bottom surface of the filter tube, and the conical liquid outlet passes through the interlayer plate.

[0007] As an improvement, a liquid inlet is provided on one side of the top of the filter box, an impurity discharge port is provided on the side of the filter box, the impurity discharge port is located above the partition plate, and an enzymatic solution outlet is provided on the bottom of the filter box.

[0008] As an improvement, one side of the impurity discharge port and the enzymatic hydrolyzate outlet is provided with a stop valve.

[0009] As an improvement, the outer wall of the filter tube is sealed and connected to the ultrafiltration membrane via a rubber gasket.

[0010] As an improvement, the tapered liquid outlet is connected to the central through hole of the partition plate by welding.

[0011] As an improvement, the top cover above the filter box is a detachable structure, and a fixing groove for fixing the filter tube is provided below the top cover of the filter box.

[0012] The advantages of the present invention over the prior art are that an interlayer plate is arranged in the filter box, and a plurality of filter tubes are installed in the through-hole grooves of the interlayer plate. When a large amount of enzymatic hydrolysate is poured into the filter box, it can be filtered through the ultrafiltration membrane wrapped around the filter tube. The filtered purified liquid flows through the liquid groove on the filter tube to the conical liquid outlet, and finally flows into the enzymatic hydrolysate outlet on the bottom surface of the filter box.
