It is a specifically developed machine for screening jobs of continuous type. A rotating screen with simultaneously rotating paddles inside which accelerates material for faster screening operations. A brush is also provided for cleaning the surface and enabling removal of chocking incidents.

Application In:

• Food, Pharma, Chemical, Minerals, Guar Gum / Starch / Cellulose etc.

The Rotary Siever break up soft agglomerates and propel individual particles through the screen while rejecting hard lumps and trash. This makes ease of screening even to the powders that has poor flow ability. A compact appearance, quiet operation, and high output make this rotating screen a highly acceptable for the various applications of the powder screening. These are available in various material of constructions.

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. NaOH

Generally, the reaction is as follows:

• Solvent Cellulose caustic - alkali cellulose
• Alkali cellulose MCA Na CMC NaCl

Functionality:

CMC dissolves rapidly in cold water and mainly used for controlling viscosity without gelling (CMC, at typical concentrations, does not gel even in the presence of calcium ions). 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.
