Chinatown Grain Machinery Co., Ltd. provides complete machinery and service for food production and grain processing industries, such as wheat flour mill, fodder factory, and rice processing plant. Thus far, our products include conveying equipment, cleaning equipment, flour milling equipment, and so on. They have been recognized by a number of customers both at home and abroad.
Since our founding, we have been focusing on the grain processing techniques and machinery development. We have accumulated a great deal of experience in both fields.
We have designed a range of machines and technical solutions for the whole grain, edible oil and food processing industry chain, such as collecting, storing, cleaning, grading, sieving, grinding, mixing, production, shape forming, and packing.

Our 500tpd wheat flour processing plant equipment has a production capacity of 200-500 tons/day. These machines are mainly installed in reinforced concrete buildings or steel structural plants, which are generally 5-to 6-storey high (including the wheat silo, flour storage house, and flour blending house).
Our flour milling solutions are mainly designed according to the American wheat and Australian white hard wheat. When milling a single kind of wheat, the flour extraction rate is 76-79%, while the ash content is 0.54-0.62%. If two kinds of flour are produced, the flour extraction rate and ash content will be 45-50% and 0.42-0.54% for the F1 and 25-28% and 0.62-0.65% for the F2. Specifically, the calculation is based on the basis of dry matter. The power consumption for the production of one ton of flour is no more than 65KWh on normal conditions.

CLEANING SECTION:
In the cleaning section, we adopt drying type cleaning technology. It normally includes 3 times sifting, 3 times scouring, double times de-stoning, one time purifying, 4 times aspiration, double time dampening, 3 times magnetic separation and so on.
In the cleaning section, there are several aspiration systems which can reduce the dust spray-out from the machine and keep a good working environment.
This is a standard and complicated thorough flow sheet which can remove most of the coarse offal, middle size offal and fine offal in the wheat which contents about 2-3 percentage offal. Of course if the wheat is clean enough and the less machine will be used and the investment will be lower.
MILLING SECTION:
In the milling section, there are four types of systems to mill the wheat to flour. They are 4-Break system, 8-Reduction system, 2-Semolina system and 2-Tail system. Purifiers are specially designed to get more pure semolina sent to the Reduction which improves the flour quality by a large margin. The rollers for Reduction, Semolina, and Tail systems are smooth rollers which are well blasted. The whole design will insure less bran mixed into the bran and the flour yield is maximized.
Thanks to the well designed pneumatic lifting system, the whole mill material is transferred by high efficiency High pressure fan. The milling room will be clean and sanitary for aspiration adoption.
BLENDING & PACKING:
Electrical control and management:
In this part, we will supply electrical control cabinet, signal cable, cable trays and cable ladders, and other electrical installation parts. The substation and motor power cable is not included except customer specially required.
PLC control system is an optional choice for customer.
In PLC control system, all the machinery is controlled by Programmed Logical Controller which can insure the machinery running stably and fluently. The system will make some judgments and do reaction accordingly when any machine is in fault or stopped abnormally. In the same time it will alarm and remind the operator to settle the faults.
Schneider series electrical parts are used in out electrical cabinet. The PLC brand will be Siemens, Omron, Mitsubishi and other International Brand. The combination of a good designing and reliable electrical parts insures the whole mill running smoothly.
