5, introduction for some mainly single machines 

5.1 Stainless steel damper: 

For the Damper, we use the double section kind with stainless steel material.

Bi-Direction screw, prevent free water,  Intensive intermixing , Stainless steel screw leaf and outside, no rusty.  Special bending and welding technology make sure no Leaking.

5.2 moisture Bin

This price includes the moisture Bin already. It is stainless steel, anty-rusty, long life use time.

5.3 degerminating system: 

For degerminating system, we use the two times degerminate, it can produce the high quality maize grits as you need. The Degerminator we have the patent already, it use the Japan technology.

5.3 Steaming tank for Arepa flour mill: 

Asorption and introduction of British and American technology,The preparation time is 45-60 minutes,

and the gelatinization degree is adjustable 65-78%. The steam equalization system ensures that the samp

is evenly matured during the preparation process.

5.4 Flaking mill

For the Flaking mill, it use the automatic Pneumatic control.

The speedy and tardy grinding rolls are driven by triple-wheel toothed belts with advantages of high power transmission, no step losses, no deflection, stable running, and low noises.

• High nickel-chromium-molybdenum alloy roll, alloy layer thickness is 30±5mm.
• The contact material adopts all stainless steel design, which is durable.
• Equipped with balanced feeding system, patented balanced  feeder. SEW reducer, SKF bearing.
• Square bearing seat; equipped with high-efficiency energy-saving intermittent high-pressure pump station design,independent PLC hydraulic automatic control system.
• Fully enclosed structure, steam recovery device.
• Patent online press The thickness of the corn flakes can be adjusted at the same time, without the need to stop the material and separate the rolls; increase the work efficiency

5.5 Dryer in Precooked maize mill line: 

• Digest and absorb the new type of granular material drying and cooling equipment produced by British company, a new type of product independently developed on the basis of digestion and absorption with reference to foreign advanced models. With the historical cooler and counter current currently in use Compared with the dry cooler, it has the characteristics of strong drying and dehydration capacity and good cooling effect. The temperature of the hot air drying inlet can be as high as (about 110°C), and the moisture of the material can be reduced from 20% to below 14%.

• The box body is made of aluminum-zinc-coated sheet and processed by numerical control equipment; the bottom row ventilation plate is  made of 304 stainless steel one-time stamping, and it is evenly dried and does not leak.

• Equipped with: material level switch; temperature sensor; reducer frequency conversion speed regulation system; stainless steel chain drive system; air network drain condensate system to prevent condensate from falling on the material.

5.6 Pneumatic Roller mill

5.7 sifter

1) Material: High-strength alloy steel
2)up and down sifter circles with steel plate overall by bending
3)Transmission system using spring force component institutions
4)Sieve frames of wood coated with synthetic resin,without backwire
5)All the inside walls as well as the doors are provided with high-grade insulation
6)Vertical and horizontal clamping system

5.7  Impulse dust filter

In the flour section, it use the Impulse dust filter , not the dust cloth.

This can make the whole workshop cleaning and fewer flour dust.
