Maize Mill System – Hurricane- 2.5TPH

Description

ABC Hansen Africa has developed over the past 20 years, a compact, single level Maize Milling Plant – to produce high quality, degerminated, super and special maize meal – also known as breakfast and roller quality maize meal.

For a technical datasheet on the plant – please click here: Maize Hurricane Super 2.5TPH 2021 for yields and space requirements etc,

The advantage of using a roller mill instead of a hammer mill when milling the samp and chips – is an improved yield of strict definition super maize meal – as the roller mill mills using a cutting action, where the hammer mill uses a pulverizing action – thus the roller mill creates less fine particles – increasing the yield of super, and reducing the yield of special meal.

The plant designed to be able to be installed in most warehouse and factory buildings, without special adjustments necessary to the floors or roof structures – to reduce the entry cost of owning a highly efficient maize milling plant.

A process flow is as follows:
The grain is received from silos or from bags via an auger (Augers 165mm | ABC Hansen Africa) that is speed controlled via a Variable Frequency drive (Variable Frequency Drive (VFD) 2.2-30KW | ABC Hansen Africa) – and fed into the Quaill II eccentric cleaner (Cleaner eccentric – Quaill II. 2-3TPH capacity | ABC Hansen Africa) where the maize is cleaned of over and under sized particles. The Hurricane system is fitted as standard with an aspiration unit on the cleaner (Aspiration Channels | ABC Hansen Africa) coupled with a 3KW fan and cyclone (Blowers & Fans | ABC Hansen Africa)
After cleaning, the maize is discharged into a dampener (Dampener | ABC Hansen Africa) with a dampener control unit, which adds water to the maize.
After dampening, the grain is conveyed to a conditioning bin (Hopper bins – steel – 0.5m³-26m³ | ABC Hansen Africa), where the maize is allowed to condition for 1 hour, giving time for the water to penetrate the outer skin of the maize, making it more elastic, allowing the degerminator peel the bran off the endosperm in large pieces, increasing the yield and the efficiency of the degerminator.

After conditioning, the maize is conveyed from the conditioning bin to the DG3000 Degerminator ( Degerminator | ABC Hansen Africa) which removes the bran and the germ meal from the maize kernel (hominy chop), discharging the hominy chop from the degerminator, and collected by an air transport system – at a single cyclone discharge point for all the chop, while the samp and chips (degerminated maize) are discharged through two aspiration channels (Aspiration Channels | ABC Hansen Africa) to remove the remaining bran and germ meal by air, and are then collected and conveyed to the roller mills.

The Hurricane roller mill (Roller mills | ABC Hansen Africa) then mills down the samp and chips to a maize meal, and the meal is then conveyed from the roller mill to 2 mini plansifters (Mini-Plansifter | ABC Hansen Africa) where the meal is graded into special and super quality meal.

The meal is then bagged off from the bagging outlets on the plansifters (outlet 1 and 3 are mixed for special, and outlet 2 is for super) and are then weighed on 2 x platform scale (Scale Platform | ABC Hansen Africa) and the bags are then stitched closed with a hand held bag stitcher (Collins Bag stitcher – handheld | ABC Hansen Africa)

Optionally for bagging – two semi-automatic tipscale bag scale (Bagging System | ABC Hansen Africa) can be used in conjunction with a auger, and a fixed head stitcher with belt conveyor can be used for stitching (Fixed Head Pedestal Bag Stitcher | ABC Hansen Africa).

Another option is to add a dosing unit to the system, for adding vitamins and minerals to the meal before packaging – when fortification of the meal and flour is required (Dosing unit | ABC Hansen Africa)

The entire plant is controlled from a motor control centre (Motor control centre – in IP55 enclosure – per control unit` | ABC Hansen Africa) – connected with a cabling set.
