1. Mix the sodium carboxymethyl cellulose directly with water to prepare a paste-like glue solution and then set aside.
When configuring the sodium carboxymethyl cellulose paste, first add a certain amount of clean water into the batching tank with a stirring device, and when the stirring device is turned on, it should sprinkle the sodium carboxymethyl cellulose slowly and evenly to the In the batching tank. Then keep stirring to make the sodium carboxymethyl cellulose and water completely fuse, and the sodium carboxymethyl cellulose can be fully melted. When dissolving sodium carboxymethyl cellulose, the reason why it should be evenly distributed and constantly stirred is to prevent the occurrence of agglomeration and agglomeration when the sodium carboxymethyl cellulose meets water, and reduce the problem of sodium carboxymethyl cellulose dissolution and increase the dissolution rate of sodium carboxymethyl cellulose.
The stirring time is not the same as the time for the sodium carboxymethyl cellulose to completely dissolve. They are two different concepts. Generally speaking, the stirring time is much shorter than the time required for the complete dissolving of the sodium carboxymethyl cellulose. The time required depends on the specific situation. The basis for determining the stirring time is: when the sodium carboxymethyl cellulose is uniformly dispersed in the water and there is no obvious large agglomerate object, the stirring can be stopped, and the sodium carboxymethyl cellulose and water are allowed to infiltrate and merge with each other in the standing still solution. The basis for determining the time required for the complete dissolution of sodium carboxymethyl cellulose is as follows:
(1) Sodium carboxymethyl cellulose and water are completely bonded, and there is no solid-liquid separation between CMC and water.
(2) The mixed paste is in a uniform state, and the surface is flat and smooth;
(3) The color of the mixed paste is close to colorless and transparent, and there are no granular objects in the paste. From the time when the sodium carboxymethyl cellulose is put into the mixing tank and mixed with water, until the sodium carboxymethyl cellulose is completely dissolved, the time required is between 10 and 20 hours.
2.Firstly the sodium carboxymethyl cellulose is mixed with dry raw materials in a dry manner, and then poured into water to dissolve.
During operation, first put the sodium carboxymethyl cellulose and the dry raw materials in a certain ratio in a stainless steel mixer, close the top cover of the mixer, and keep the materials in the mixer in a sealed state. Then, turn on the mixer to fully mix the sodium carboxymethyl cellulose and other raw materials. Then, sprinkle the mixed sodium carboxymethyl cellulose mixture slowly and evenly into the mixing tank filled with water, and stir continuously. The subsequent operations can refer to the first dissolution method mentioned above.
3.When using sodium carboxymethyl cellulose in liquid or pulpy food, it is best to homogenize the mixture in order to obtain a more delicate tissue state and stabilization effect.
The pressure and temperature used during homogenization should be determined according to the characteristics of the material and the product quality requirements.
