Daily maintenance of twin-screw extruders involves process, selection, or operational management issues related to food processing and production equipment.The actual solution should be confirmed based on raw material characteristics, target product specifications, production scale, and on-site conditions, and should not be determined solely by the parameters of a single piece of equipment.

Key Points for Daily Maintenance of Twin-Screw Extruders

Keeping the twin-screw extrusion puffing machine clean not only produces higher-quality products but also reduces the failure rate, ensuring continuous production.The basic elements of maintenance for twin-screw extrusion and puffing equipment are inspection and cleaning.

The inner walls of the cooling water pipes in twin-screw extrusion puffing equipment are prone to scaling, while the outer walls are susceptible to rust and corrosion; careful inspection should be conducted during maintenance.Excessive scale buildup can clog pipes, resulting in failure to achieve the expected cooling performance;Severe rusting can easily lead to leaks.Therefore, descaling and corrosion protection measures for the cooling system must be implemented during routine maintenance.After the equipment has been in operation for a period of time, a comprehensive inspection of the twin-screw extrusion puffing machine should be conducted to verify the tightness of all bolts, and inspection records should be properly documented.Anti-loosening measures should be applied to thread connections that are prone to loosening, and they should be promptly tightened to prevent equipment failures caused by loosening during production.

Basic maintenance work includes cleaning the equipment and lubricating the moving parts of the twin-screw extrusion and puffing machine.For example, wear of the gears inside the gearbox can produce iron filings or other impurities.Inspect the wear condition of the gears and bearings, and keep proper records.While cleaning the gears, the reducer lubricating oil should be replaced regularly.In addition, the motor, control instruments, and other piping and working components of the twin-screw extrusion puffing machine should be inspected and adjusted.If a power outage occurs suddenly during production, the main drive and heating systems will stop operating.After power is restored, each section of the barrel must be reheated to the specified temperature and held for a period of time before starting the extrusion and puffing equipment.

What conditions should be considered during implementation or selection?

First, it is essential to clarify the product type, raw material state, formulation direction, and expected finished product requirements.For projects involving extrusion, forming, drying, frying, conveying, seasoning, or packaging, the processing capacity and cycle time of each stage must be matched to avoid discrepancies between individual equipment capacity and the overall line requirements.

Secondly, the installation plan should be evaluated in conjunction with the workshop's spatial layout and utility conditions, including power supply, water supply, steam, or gas.Equipment configuration should also take into account long-term operational factors such as cleaning, maintenance, safety protection, spare parts supply, and operator training.Any process or equipment capabilities mentioned in this document are for reference only in the context of solution discussions and preliminary assessments.Specific model numbers, power ratings, production capacities, temperatures, and times shall be subject to the official technical proposal and the results of trial runs or on-site verification.

Frequently Asked Questions

Can the equipment be determined directly based on the standard configuration?

Not recommended.The equipment configuration is influenced by different raw materials, product structures, target production capacities, and downstream processes.It is more prudent to confirm the product and process conditions before proceeding with the configuration assessment.

How to obtain more targeted advice?

It is recommended to prepare product images or sample information, raw material and formulation guidelines, target production capacity, existing workshop conditions, and planned downstream equipment configurations.Dayi Machinery can further discuss the applicable process routes and equipment configuration options based on this.
