TECHNICAL KNOWLEDGE AND EXPERIENCE
The wide range of Cimbria Delta screen cleaners ensures excellent efficiency and purity in the cleaning of all kinds of crops by removing unwanted elements and potentially dangerous impurities with high precision. The efficient and gentle Delta cleaning process secures the quality and germinating capability of the seed by keeping the quantity of damaged seeds to an absolute minimum. The result is increased product value and higher earnings.
The Delta cleaner 150 series has been developed for the high capacity pre-cleaning of grain, peas and rape seed, as well as industrial cleaning of grain for milling and malting barley. The machine’s large screen area with its accurately matched stroke and frequency is complemented by Cimbria’s highly efficient pre-suction and after-suction system.
Research, test and training take place at Cimbria’s full-scale seed-grain plant. On request, local test centres carry out test cleaning of any given product and determine the optimum screen perforations for special processes.
Delta Cleaners are available in different series with more than 30 different models to choose from offering capacities from 1 t/h fine-cleaning up to 450 t/h pre-cleaning.
EXAMPLES OF PRODUCTS CLEANED IN A DELTA CLEANER
DELTA CLEANER CONSTRUCTION
The Delta cleaners 150 series are constructed with large screen areas and Cimbria’s highly efficient pre-suction and after-suction system. The suction system extracts light impurities from the material both at the machine inlet and outlet. The exhausted waste, dust and lightweight waste are deposited in expansion chambers and conveyed to the machine outlets by discharge augers equipped with a multi-flap air system to prevent false air from entering the machine. The expansion chambers are designed for connection to a separate exhaust fan. The self-cleaning screens with ball boxes, containing rubber balls, are manufactured in a standard size which makes them fit all other types of Delta screen cleaners. They are available with various round or oblong perforations according to the material to be cleaned.
INLET WITH SHAKER FEEDER
Optimal feed over the full width of the cleaner is achieved with a shaker feeder. The shaker feeder is designed to handle all kinds of grain and seed through gentle and controlled feeding. The feeding rate is controlled through step-less speed adjustment, thus ensuring the required capacity for any application.
PRE- & AFTER-SUCTION
All Cimbria cleaners are equipped with a two-pass air separation system. The pre-suction is designed to remove dust and light foreign material at the inlet of the machine to reduce the amount of dust and fines inside the machine. This ensures a nice and even flow of product on the screens. The after-suction is designed to collect remaining husk and fines in the clean grain at the final outlet of the cleaner.
The 150 series cleaners are designed with the option of a flexible flow system which offers the operator the possibility of using the optimum flow for a specific application. With changeable outlets and dividers the operator can change between different flows. The optimum flow ensures maximum capacity and quality.
The Cimbria screens are designed for highest possible efficiency and are effectively kept clean by rubber balls in special designed ball boxes. A high percentage of open area ensures maximum capacity in the machine.
The ball boxes are designed so that it is not necessary to remove the boxes for changing the screens. Like all other Delta screen cleaners the base and the frame of the 150 series screen cleaners is a very rigid construction built from heavy gauge pressed steel. The screen boats are manufactured from selected insect-resistant and moisture-resistant marine plywood.
The screens shoes are made in coated marine plywood to ensure a long lifetime. With its strong and flexible structure, this material is highly resistant to the constant movement in the machine. Wear areas inside the screen shoes are protected by wear plates.
The eccentric system is designed to drive the screen shoes and create a gentle flow of product through the machine. The weight of each screen shoe is optimized to ensure a wellbalanced and smooth motion. Supplied as standard with a flywheel to recapture the force created by the movement of the screens shoes and reduce power consumption.
ELECTRONIC CONTROL SYSTEM
The 150 series cleaners can be supplied with an electronic control system. The system consists of a control panel which operates actuators and motors with integrated frequency control. The actuators operate numerous air gates inside the machine, and with digital adjustment settings ranging from 0-100, the accuracy of the settings is very high. The electronic control system includes adjustment of the shaker feeder.
Operator safety is our highest priority. The Cimbria cleaners are designed with covers to protect the operator from all moving parts. Samples from each outlet of the machine can be obtained through a specially designed sample port which ensures user-friendly and safe operation.
