Key factors for choosing a duplex cleaning machine

The compound cleaning machine is a type of seed cleaning equipment widely used in the agricultural field. It can separate impurities, incomplete particles, and heterogeneous seeds in seeds through multiple screening and wind selection systems, improving the purity and germination rate of seeds. The compound cleaning machine is usually composed of feeding device, screen system, air selection system, transmission device, and frame, etc. It has the characteristics of compact structure, easy operation, and good cleaning effect.

1. Characteristics of selected materials

The physical properties of different crop seeds vary greatly, and when choosing a compound cleaning machine, the characteristics of the material to be cleaned should be considered first:

Seed size: Different crops have different seed sizes, ranging from small seeds such as sesame to large seeds such as corn. It is necessary to choose a cleaning machine with the corresponding mesh size

Seed shape: seeds with circular, elongated, or irregular shapes require different sorting methods

Seed specific gravity: Seeds of different weights have different requirements for the wind selection system

Impurity type and content: Materials with high impurity content or complex impurities require stronger cleaning capabilities

2. Production capacity demand

Select suitable models based on production scale:

Mini machine: processing capacity of 0.5-2 tons per hour, suitable for small farms or seed companies

Medium sized machine: processing capacity of 2-5 tons per hour, suitable for medium-sized seed enterprises

Large scale machine: capable of processing over 5 tons per hour, suitable for large seed processing plants

3. Selection accuracy requirements

Different applications have different requirements for seed cleaning accuracy:

Common planting seeds: relatively low purity requirements

Breeding of superior varieties: requires high purity and clear selection

Export seeds: usually have strict cleaning standards

4. Technical parameters of the equipment

Number of sieve layers: The compound cleaning machine usually has 3-5 layers of sieve, and the more layers, the finer the sorting

Screen type: punching screen, weaving screen, etc. Different screens are suitable for different materials

Wind selection system: adjustable air volume range, air duct design affects cleaning effect

Power configuration: The motor power should match the processing capacity requirements

5. Degree of automation

The automation level of modern duplex cleaning machines varies greatly:

Basic type: manually adjust parameters such as screen inclination angle and air volume

Semi automatic type: Some parameters can be electrically adjusted

Fully automatic type: equipped with PLC control system, can store various crop cleaning parameters

Choosing the appropriate compound cleaning machine is a decision-making process that requires comprehensive consideration of multiple factors. Users should weigh various technical parameters, performance indicators, and price factors based on their actual situation and choose the appropriate equipment.
