Question: Changeover Cleaning: When switching products, what is the complexity and time required for equipment cleaning and process changeover?

Detailed Answer:

For R&D institutions that frequently change product formulations or factories engaged in multi-variety production, the convenience of process changeover directly impacts equipment utilization and production efficiency. Our design fully considers this requirement.

I. Core Design: Completely Removable Material Support System

The primary potential pathway for product contamination is through material carriers/crucibles. Our solution adopts a completely removable carrier design that is independent of the furnace body.

Workflow: When product changeover is needed, simply lift or push out the entire carrier assembly containing the previous batch from the furnace after unloading. A new, clean carrier (already loaded with new material or pre-cleaned) can then be loaded into the furnace.

II. Changeover Process and Time Assessment

Standardized Operation:

1. Unload and cool down the furnace.

2. Lift out the old carrier and place it in a designated area.

3. Lift in the prepared new carrier.

4. Close the furnace door and start the new cycle.

Time Advantage: The entire changeover process does not involve complex internal cleaning of the equipment and can typically be completed within 1-2 hours, significantly reducing equipment downtime. Cleaning of carriers can be performed in a dedicated area outside the furnace, without interfering with equipment operation.

III. Value of This Solution

• Efficient and Flexible: Enables rapid product changeover, accommodating small-batch, multi-variety production modes.

• Eliminates Cross-Contamination: Physically isolates contact paths between different products.

• Reduces Labor Intensity: Simple operation eliminates the need for personnel to enter the furnace for tedious cleaning.
