Extending the service life of food extrusion puffing machines involves process, equipment selection, and operational management issues in 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 single equipment parameters.

Key Points for Extending the Service Life of Food Extrusion Puffing Machines

Food extrusion puffing machines have a certain service life. Implementing proper maintenance measures during use can ensure longer equipment operation.

When a screw channel blockage is detected, do not stop the machine immediately.Stop feeding first, and allow the equipment to continue running for a short period until a burnt smell is detected.This measure prevents the nozzle from seizing with the spiral sleeve.If the nozzle or spiral sleeve is seized and cannot be removed, do not strike it with force.It can be detached from the machine body, briefly heated in a fire, and then easily removed.

During the initial startup phase, if the nozzles fail to extrude formed products, it is usually due to excessively high nozzle temperatures.The cause may be that the material is too dry, foreign objects have entered the screw channel, or the feeding has been interrupted.

After stopping the feeding at the end of production, allow the main unit to run empty for 1 minute to discharge any residual material from the barrel before shutting down.

Before startup, disassemble the head, transmission components, and lead screw, and other working parts. Carefully remove scale and oil stains from the transmission parts and lead screw. Only after cleaning and drying may the components be reassembled.

When in use, start the main unit and let it run idle for 1 to 2 minutes, then slowly feed material into the inlet.When the material roughly fills the annular groove at the head of the screw shaft, pause feeding and use friction for preheating.Resume normal feeding when the head temperature rises, the internal pressure increases, and the nozzle begins to discharge material.Since the temperature and pressure inside the barrel have not yet reached the normal process requirements at this stage, the feeding rate should be increased slowly and gradually.

Feeding should be continuous and uniform, and the material must remain dry; otherwise, screw channel blockage is highly likely.

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 formal 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.Different raw materials, product structures, target production capacities, and downstream processes can affect the equipment configuration.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.
