Grain processing equipment by plant stage: cleaning, milling, cooling and handling

Grain processing on this site is mostly plant equipment from three Zhejiang makers, and the easiest way to choose is to follow the grain through the line: intake cleaning and destoning, rice milling and its by-product streams, feed cooling, and the conveyors, gates and filters that tie the stages together. Jiaxing Guangchang Machinery supplies most of the pages and also designs and installs complete lines; Ninghai Zhanying Grain Machinery specialises in cleaners, destoners and grading screens; Shaoxing Shanghe Machinery Manufacturing builds Fengdeng rice milling and polishing machines.

Cleaning starts with coarse debris. The TCQY63 drum pre-cleaner is the smallest model on its sheet, turning at 25 rpm on a 0.75 kW motor with 12 m³/min of air and a 350 kg frame; its crop capacity rows carry no printed unit, so ask for the unit and the screen layout for your grain. Fine cleaning and grading follow on vibrating screens. Guangchang's TQLZ vibrating cleaning sieve runs in six sizes from TQLZ100 at 8 t/h to TQLZ250 at 20–35 t/h, and Guangchang ties output to the screen-hole size, so choose the screen first and the model second. The Zhanying TQLZ150 has two decks, two vibration motors at 2×0.55 kW, a reference rate of 15–18 t/h and 6000–6600 m³/h of aspiration air.

Heavy impurities need a destoner. Guangchang's TQSX and TQSF gravity stoners come in five arrangements, from standard suction to a double-ply unit with 0.37×2 kW vibration motors and a 1.5 kW internal fan; pick the arrangement for paddy or wheat first, then the size, and get the capacity unit in writing. Tramp iron comes out with permanent magnets: the TCXT magnetic cylinders are rated 10–100 t/h at ≥3500GS, while the TCXP separators handle 5–15 t/h and carry a printed removal rate of ≥99%. Neither needs a motor.

In a rice mill, the MGCZ double-body paddy separator sits after the husker and returns unhusked paddy for another pass. The MGCZ46×20×2 gives 4.5–5.5 t/h of brown rice at 3 kW and the MGCZ60×20×2 gives 6.5–7.5 t/h at 4 kW, with ≤5 grains/kg of paddy left in the brown rice. Finishing is a separate stage: the Fengdeng S8 rice polisher is rated 6–8 t/h with 45×2 kW of main-machine power, a 22 kW blower at 6500 m³/h and 2500–3000 Pa, and weighs 2500 kg. Side streams can be worked as well, with KXFL bran and DKTL hull recovery devices that run off the mill's air network; KXFL handles 0.45, 0.6 or 0.9 t/h of bran.

For feed lines, the SKLB counterflow coolers cover six sizes from SKLB2.5 to SKLB12 at 5 to 30 t/h, built with either slide-valve or pendulum-flap discharge under the same model codes. Name the discharge type on the order and ask Guangchang for the cooling-air volume and pressure.

Handling ties the plant together. The TDTG bucket elevator spans twelve sizes from 1–4 t/h to 90–120 t/h on 2.2 to 37 kW. Horizontally, the TGSS, TGSU and TLSS grain conveyors cover drag and screw duties up to 260 t/h, and the drive is sized from your route length. A TFPX rotary distributor sends one inlet to a chosen outlet at 30–50 t/h, TZMQ and DZMQ gates open and shut the flow by cylinder or electric screw, and TBDQ three-way diverters switch chutes between outlets. The TDSL mobile belt conveyor loads bulk or bagged grain at ≥50 t/h with a head height adjustable from 2.5 to 8.8 m. Dust collection closes the loop with TBLM pulse bag filters, whose low-pressure sheet lists 1800, 2000 and 2400 mm bags and resistance under 1470 Pa.

Prepare a category-specific sourcing brief · Read procurement guides

Compare the right fields

Read competing quotations on the same basis

Compare quotations stage by stage, not as a pile of model codes. For each machine, set the rated throughput, the grain it was rated on and the unit beside the motor and air figures, and line up screen or magnet specification for cleaners and finish target for polishers. Where Guangchang quotes a project package, ask for a schedule that marks which units it builds and which come from other brands, and check that the elevator, conveyor and distributor capacities match the slowest process machine. Price the aspiration fans, ducting and controls on their own lines so two offers carry the same scope.

Questions for your supplier

• What t/h figure applies to my grain and impurity level, and on which screen?
• Which aspiration fans, ducting and controls are included in the price?
• Which units in the package are your own build and which come from other brands?
• Can you confirm in writing any capacity or air figure printed on the sheet without a unit?

Send these questions with your enquiry and ask for the model-specific documents in the quotation.
