Description

Methylcellulose dispersing device

Technical Field

The utility model relates to the technical field of stirring devices, in particular to a methylcellulose dispersing device.

Background

The methylcellulose is white or quasi-white fibrous or granular powder, odorless, almost insoluble in absolute ethyl alcohol, diethyl ether and acetone, rapidly dispersible and swellable in hot water at 80-90 ℃, and rapidly soluble after cooling. The aqueous solution of methyl cellulose is quite stable at normal temperature and can gel at high temperature, and the gel can be mutually converted with the solution along with the temperature.

At present, in the process of preparing a methylcellulose culture medium, a hot water method is generally adopted, and two typical methods for preparing a methylcellulose solution by using the hot water method are as follows:

the first method is to put a required amount of hot water into a container and heat it to about 70 ℃; methyl cellulose is gradually added under slow stirring, and initially the methyl cellulose floats on the surface of water (since methyl cellulose is insoluble in hot water, the initial methyl cellulose can be uniformly dispersed in hot water), and then a mixture is gradually formed; the mixture was cooled under stirring. This method takes a long time for a large volume of the mixture to cool to room temperature.

The second method is to prepare a hot water slurry by adding a desired amount of 1/3 or 2/3 of water to a vessel and heating to 70℃to disperse the methylcellulose according to the first method. Then the remaining amount of cold water or ice water is added to the hot water slurry. After stirring, the mixture was cooled.

The two methods are all required to gradually add the methylcellulose under the condition of slowly stirring, the process is long in time consumption and laborious to operate, and on the other hand, the addition amount of the methylcellulose is controlled manually, so that the methylcellulose is difficult to control uniformly, and the requirement on experimental staff is high.
