Industrial Machine Solution has developed over the past 20 years, a compact, single level Maize Milling Plant – to produce high quality, degerminated, super and special maize meal.
For a technical datasheet on the plant – please click here: Maize Hurricane Super 1.5TPH 2020 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.
For a write up and definition of the types of maize meals and different milling options – see here: Milling Maize Options
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 | Industrial Machine Solution) that is speed controlled via a Variable Frequency drive (Variable Frequency Drive (VFD) 2.2-30KW | Industrial Machine Solution) – and fed into the Quaill I eccentric cleaner (Cleaner eccentric – Quaill I. 500kg – 1,500kg/hour capacity | Industrial Machine Solution) 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 | Industrial Machine Solution) coupled with a 3KW fan and cyclone (Blowers & Fans | Industrial Machine Solution)
After cleaning, the maize is discharged into a dampener (Dampener | Industrial Machine Solution) 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 | Industrial Machine Solution), 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 Degerminator ( Degerminator | Industrial Machine Solution) 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 discharge point for all the chop, while the samp and chips (degerminated maize) are discharge through two aspiration channels (Aspiration Channels | Industrial Machine Solution) to remove the remaining bran and germ meal by air, and are then collected and conveyed to the hammer mill.
The Hurricane roller mill (Roller mills | Industrial Machine Solution) then mills down the samp and chips to a maize meal, and the meal is then conveyed from the roller mill to a rotary sifter (Rotary sifter | Industrial Machine Solution) where the meal is graded into special and super quality meal.
The meal is then bagged off from the bagging outlets on the rotary sifter (outlet 1 and 3 are mixed for special, and outlet 2 is for super) and are then weighed on a platform scale (Scale Platform | Industrial Machine Solution) and the bags are then stitched closed with a hand held bag stitcher (Collins Bag stitcher – handheld | Industrial Machine Solution).
Optionally for bagging – a semi-automatic tipscale bag scale (Bagging System | Industrial Machine Solution) 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 | Industrial Machine Solution).
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 | Industrial Machine Solution)
The entire plant is controlled from a motor control centre(Motor control centre – in IP55 enclosure – per control unit` | Industrial Machine Solution), which is included in the price – as well as a cabling set
