Key factors in selecting a compound cleaning machine

The compound cleaner is a seed cleaning equipment that is widely used in the agricultural field. It uses multiple screening and air selection systems to separate impurities, unfilled particles, and different types of seeds from the seeds, improving the purity and germination rate of the seeds. The compound cleaner is usually composed of a feeding device, a screen system, an air selection system, a transmission device, and a frame, and has the characteristics of compact structure, easy operation, and good cleaning effect.

1. Characteristics of cleaning materials

The physical characteristics of different crop seeds vary greatly. When selecting a compound cleaner, the characteristics of the material to be cleaned must 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 appropriate screen size

Seed shape: Round, elongated, or irregularly shaped seeds require different cleaning methods

Seed specific gravity: seeds with different weights have different requirements for the wind selection system

Type and content of impurities: Materials with high impurity rates or complex impurities require stronger cleaning capabilities

2. Production capacity demand

Choose the appropriate model based on the production scale:

Small 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: processing capacity of more than 5 tons per hour, suitable for large seed processing plants

3. Requirements for cleaning accuracy

Different purposes have different requirements for seed cleaning accuracy:

Common planting seeds: relatively low purity requirements

Improved variety breeding: requires high purity cleaning

Exporting seeds: usually have strict cleaning standards

4. Technical parameters of equipment

Number of screen layers: Compound cleaning machines typically have 3-5 layers of screens, with more layers providing finer sorting

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

Air selection system: adjustable air volume range, air duct design affecting cleaning effect

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

5. Degree of automation

The automation level of modern compound cleaning machines varies greatly:

Basic model: Manual adjustment of screen tilt angle, air volume, and other parameters

Semi-automatic type: some parameters can be adjusted electrically

Fully automatic model: Equipped with a PLC control system, capable of storing multiple crop cleaning parameters

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