1. Classification and Detailed Explanation of Control Methods
1.1 Principles for Classifying Control Methods:
Ø Cost
Ø Automation level
Ø Inclusion of PLC, computer, or touch screen
1.2 Control Method Classification
(1)Mimic Panel Control:A purely button-based control mode.
Advantages: Low cost, low automation level. Typical Usage: Simple processes, such as basic silo or grinding processes.
(2)Computerized Recipe + Mimic Panel Control:
Combines button control with computer-operated recipe control for the mixing section.
Advantages: Economical and practical, offering more flexibility in the control of batching while maintaining simplicity. Typical Usage: Common in feed mills with moderate complexity, balancing cost and functionality.
(3)Fully Computerized Control:All equipment can be controlled via a computer.
Advantages: High automation level, better data tracking, and centralized control. Typical Usage: High-end systems where precision and full automation are required, such as large-scale production lines.
(4)Computerized Recipe + Mimic Panel Control + Standalone Touchscreen:
A combination of button-based control, computer recipe operation, and some complex machinery controlled via touchscreen.
Advantages: Cost-effective, offering a blend of practical control and some automated functions where needed. Typical Usage: Common in systems that need some automation for specific machines but where full automation is not necessary.
² Mimic Panel Control
Simple process with equipment that only requires sequential start/stop, such as silo process, simple feeding + grinding process, raw material extrusion process (extruder controlled by button-type on-site control box), and pelleting process (pellet mill controlled by button-type on-site control box).
PIC 1:A simple silo process can meet control requirements using a mimic panel system—cost-effective and practical, with intuitive button-based operation.
PIC 2:A single grinding line with minimal equipment can meet control requirements using simple buttons and knobs.
PIC 3:Raw material extrusion involves more complex equipment, but from an economic perspective, a mimic panel still effectively meets control requirements.
PIC 4:For livestock and poultry feed pelleting, feed rate is controlled by knobs and valves are adjusted manually—resulting in low automation and low cost.
² Computerized Recipe + Mimic Panel Control
The relatively simple livestock and poultry feed process typically includes feeding, grinding, batching, mixing, and pelleting/packaging. The pellet mill is controlled by a button-based control box on-site, while the batching section requires computer operation.
PIC 1:The complex batching section is controlled by a combination of computer and PLC, offering an economical and practical solution that meets automation requirements!

² Fully Computerized Control
Applicable to any form of production process!
Operational efficiency is greatly improved, leading to increased effective working hours and higher output. The automatically recorded production data, transmitted paperlessly, provides production managers with accurate and real-time information.
PIC:Any process can be fully computerized
² Computerized Recipe + Mimic Panel Control + Standalone Touchscreen
Suitable for aquaculture processes, this product is designed with the customer’s economic considerations in mind!
Aquaculture feed processes are complex, involving batching, and may include pellet mills, extruders, oil spraying, vacuum spraying, and other equipment with complex logical relationships that require PLC control for individual machines.
