The first important separation stage is separation of oil-bearing germs from partially grinded Corn. Most plants today use two stages Germ Separation System for this operation. The compact, sanitary Germ Separation System consists of manifold hydrocyclones that make an instant separation using centrifugal force.
The first stage makes a selective separation for optimum purity and the second stage increases germ recovery by capturing any germ that might have bypassed in the first stage. Its distinct benefits are good abrasion resistance, cleanliness, easy maintenance and quick individual replacement (due to quick pening couplings).
The Germ Washing station is a three-stage countercurrent washing system, 50º bend screen installed in box-housing with supporting structure. The overflow of the first stage Germ Separator is introduced to the first screen while the washed water goes to the third stage screen, washing the germ.
The washed water moves in the same manner i.e., countercurrent to the first screen washing the germs and the germs are moved down from first stage to the third stage and the germs are washed cleaner and cleaner.
De-watering screens are used for dewatering maize installed before grinding mills complete with feed box & bottom hopper.
To make quality starch it is necessary to remove the soluble and insoluble remained in the starch slurry that comes from primary separator. Most of the industries use cyclone countercurrent by injecting fresh water to refine starch & to lower protein content in the slurry at as low as 0.35%.
A starch washing system may have nine or more stages with hundreds of manifolded hydrocyclone in each stage.
The objective of the milling process is to provide complete separation of component parts of the steeped corn kernels. After steeping, the grains are coarsely ground of pulp with water in coarse grinding (attrition mill) in preparation for de-germination.
Grinder has one stationary and one rotating disc. The gap between the plates can be adjusted to give the most germ free with minimum breakage with quick release spring mechanism for easy retraction attached with rotational shaft to prevent accidental damage to grinding plate due to any metallic foreign particles.
Its function is to crush the part broken maize and grit into fine pulp. It has two discs rotating in opposite direction. All the rotating parts are dynamically balanced. The gap between the plates can be adjusted with quick release spring mechanism for easy retraction, attached with rotational shaft to prevent accidental damage caused to grinding plate due to any metallic foreign particles.
In the process where all the starch is to be recovered, the underflow from the germs cyclones, containing fibre and pieces of endosperm is more thoroughly milled to recover the maximum yield of starch.
It contains a stationary and a rotating stone with retraction mechanism with rotational shaft to prevent accidental damage to grinding plates. Stone is specially made of food grade.
The function of the Fibre Washing System is to remove the Starch bonded with the Fibre. Both fine and coarse fibre is removed in a multi-stage countercurrent washing 120º bend pressure screen. It consists of seven or more stages, depending on the screen width and the plant capacity.
The multistage countercurrent washing arrangement enables maximum starch yield and high fibre recovery.
Starch slurry is passed through the strainer before feeding to starch washing system. Here the undesired substance such as abrasive materials like sand, dust, pipeline scale and similar gritty elements that could cause problems in high rotating equipment like pumps are removed.
Sifter is primarily used to sieve the starch to the desire mesh size. It is easily operated, low maintenance and is totally dust proof.
A rotary germ dryer consists of a cylinder, bunch of rotating tubes and cylinder slightly inclined to horizontal. The length and diameter of the cylinder depends on the designed capacity of the dryer.
It converts starch slurry into liquid glucose syrup continuously with indirect steam heating in the presence of hydrochloric acid at a required temperature and the output is maintained to 42 DE Glucose syrup by means of automatic control instruments.
Falling film type with thermal evaporation Single & Multi effect. Our unique design reduces power & steam consumption.
Starch dryer is flash type or pneumatic dryer, used for removing surface or unbounded moisture from a feed. Technology behind it is relatively low residence, time and moisture is flashed off, a consequential amount of evaporative cooling takes place allowing higher inlet temperature to be used without excessively heating the product.
To refine glucose syrup by deashing to remove the anionic & cationic impurities, the syrup is passed through ion exchange column (i.e., cationic and anionic column) output. The thus obtained deashed clear glucose syrup is controlled by automatic control instruments.
It is used for cooking starch slurry for conversion to malto dextrin and glucose syrup, complete with retention coil to hold converted syrup for 5 minutes.
