Stainless Steel Vacuum Flask Cleaning and Drying Furnace

The Stainless Steel Vacuum Flask Cleaning and Drying Furnace is an automated continuous surface treatment system specially designed for the manufacturing and processing of stainless steel vacuum flasks. It integrates multiple processes, including high-pressure spray cleaning, multi-stage water rinsing, water removal, and high-temperature hot air drying.Through the mesh chain conveying system, the equipment enables fully automated production line operation from inner tank cleaning, outer shell treatment, to finished product processing. It effectively removes contaminants generated during manufacturing, such as drawing oil, polishing paste, metal residues, and fingerprints, ensuring a clean and dry surface before subsequent processes.

Product Applications

1. Surface Degreasing

Removes drawing oil and welding oil residues generated during stamping and deep drawing processes.

2. Polishing Cleaning

Removes polishing paste and metal particles remaining after surface polishing processes.

3. Pre-treatment Before Coating

Provides a clean and dry surface for vacuum flask shells before painting, powder coating, or laser marking processes.

4. Finished Product Drying

Ensures complete drying of the inner and outer surfaces of vacuum flasks before vacuum inspection or packaging, preventing water stains and rust spots.

Product Parameters

Product Features

1. Thorough Cleaning Performance

Multi-angle high-pressure spray coverage with specially designed nozzles that directly clean the bottom areas of the vacuum flask inner tanks.

2. Efficient Drying Performance

Powerful air water removal combined with a hot air circulation system ensures complete drying without blind spots or water marks.

3. Energy Saving and Environmental Protection

Cleaning water is recycled and filtered for reuse. The equipment is equipped with an insulation layer to reduce heat loss and improve energy efficiency.

4. Intelligent Control System

PLC touchscreen control enables one-button operation, with digital display of temperature zones and conveyor speed.

5. Stable Operation

The transmission system runs smoothly to prevent collision, scratches, and surface damage of vacuum flasks during the cleaning process.

FAQ 

Q1: Can this equipment clean vacuum flasks of different sizes and specifications?

A: Yes. The conveyor mesh width and furnace inlet height can be adjusted to accommodate various shapes, sizes, and capacities of vacuum flasks.

Q2: What type of cleaning agent should be used?

A: It is generally recommended to use environmentally friendly neutral or mildly alkaline water-based cleaning agents, which can effectively remove oil stains without damaging the stainless steel surface.

Q3: Will the drying process damage the vacuum insulation layer of the flask?

A: No. The drying temperature is generally controlled between 80℃–120℃, which is far below the critical temperature that could damage stainless steel structures and vacuum-welded insulation layers.

Q4: What maintenance is required for daily operation?

A: Regular maintenance includes cleaning the filter screens inside the cleaning tank, checking whether spray nozzles are blocked, and applying high-temperature lubricating oil to the transmission chains periodically.

Q5: How long does it take for the equipment to reach the set temperature?

A: Under normal ambient temperature conditions, the equipment usually requires approximately 20–30 minutes for initial heating to reach the preset operating temperature.
