5 HP Centrifugal Siever, 415 V

Manufacturing Process:First cellulose reacts with caustic to form alkali cellulose then react with mono chloroacetic acid or its salt from sodium carboxymethylcellulose. During the reaction of alkali cellulose with electrification agents and in the subsequent reactions, sodium chloride (common salt) is produced as a major by-product. This is washed out together with any other byproducts or, in the case of technical-grade NaCMC, left in the product. The dried cellulose ethers are then processed into granular or powder products and in some cases modified with other additives.

As its viscosity drops during heating, it may be used to improve the volume yield during baking by encouraging gas bubble formation. Its control of viscosity allows use as thickener, phase and emulsion stabilizer (e.g. with milk casein), and suspending agent. CMC can be also used for its water-holding capacity as this is high even at low viscosity; particularly when used as the Ca2+ salt. Thus, it is used for retarding staling and reducing fat uptake into fried foods.The average chain length and degree of substitution are of great importance; the more-hydrophobic lower substituted CMCs are thixotropic but more-extended higher substituted CMCs are pseudoplastic. At low pH, CMC may form cross-links through lactonization between carboxylic acid and free hydroxyl groups.Unit Operations:Caustic Lye / Flakes storagePreparation of Sodium salt of the Monochloro acetic acid.Cellulose preparation (required particle size)Reaction unitStorage of reaction mass unsuitable packingDrying systemMilling and screening of CMCBlending of CMC to prepare the tailor-made product.Weighing packing of tech CMC
