Embodiment

[0020] See figure 1 A continuous gelatin concentration device by membrane method includes a roll-type membrane module 6 composed of a plurality of roll-type ultrafiltration membranes combined in series and parallel, and the molecular weight cut-off of the ultrafiltration membrane is 5000-10000MW.

[0021] The outlet of the roll membrane module 6 is connected to the first port of the four-way joint. The second and third ports of the four-way joint are connected to the raw glue tank 1 and the thick glue tank 8 respectively; the inlet of the roll membrane module 6 is connected to The outlet of the circulating pump 5; the suction pump 2 and the filter 4 are connected in series between the raw rubber tank 1 and the inlet of the circulating pump 5; the first shut-off valve 3 is connected in series between the suction pump 2 and the filter 4 ; The pipe between the original glue tank 1 and the outlet of the roll membrane module 6 is connected in series with a second stop valve 10; the pi...

Abstract

The invention relates to a device for continuously concentrating gelatin by membrane technology. The outlet of a rolled membrane module of the device is communicated with a first connector of a four-way joint; a second connector and a third connector of the four-way joint are respectively connected with an original gelatin tank and a thick gelatin tank; the inlet of the rolled membrane module is communicated with an outlet of a circulating pump; a sorption pump and a filter are successively connected in series between the original gelatin tank and the inlet of the circulating pump; a first stop valve is in series connection with a pipe between the sorption pump and the filter; a second stop valve is in series connection with a pipe between the original gelatin tank and the outlet of the rolled membrane module; a first butterfly valve is in series connection with a pipe between the outlet of the rolled membrane module and the thick gelatin tank; a second butterfly valve is connected in parallel between the inlet of the circulating pump and the fourth connector of the four-way joint; and the discharge hole at one side of the rolled membrane module is provided with a third butterfly valve. In the invention, the continuous gelatin concentration operation technology is applied to the gelatin concentration technique, and the device in the invention is used for replacing the conventional device for kieselguhr filter, ion exchange and high-temperature evaporation concentration processes.

Description

Technical field [0001] The invention belongs to the technical field of membrane concentration, and specifically relates to a membrane method continuous gelatin concentration device for preparing gelatin by applying a membrane method continuous operation concentration technology to a gelatin filtration and impurity removal and concentration process. Background technique [0002] Gelatin is a product obtained by partial hydrolysis of collagen in animal skin, bone and other tissues. It is an important natural protein polymer containing almost all essential amino acids except tryptophan. It is used in food, medicine, photography and The industrial sector has a wide range of uses. In the traditional gelatin production process, 3% to 5% of the gelatin solution needs to be concentrated to more than 25%, and then frozen gelatin is cut. This process traditionally uses a three-effect evaporator to evaporate and concentrate the gelatin solution. Its "one-effect" temperature is as high as 8...
