C7310 Dry Ice PCB PCBA Cleaning Machine for Industrial Surface Preparation and Deburring

During operation, the dry ice cleaning machine propels dry ice particles axially using a cylinder. An electric motor drives a chain wheel that turns a cutting disc, which shreds block dry ice layer by layer into an ice storage chamber. The shredded dry ice falls from the ice storage onto the ice discharge area. The motor drives the ice discharge shaft to rotate, bringing the dry ice to a relatively enclosed space below, where it is then blown out by high-pressure air. Under the constraint of the nozzle, the dry ice forms various jet shapes. The jet is directed at the surface requiring deburring, achieving the goal of removing burrs. The shape and intensity of the jet are determined by factors such as the shape of the surface to be deburred and the tenacity of the burrs. Adjustments are made based on these factors, including changing the size and shape of the nozzle and adjusting the motor speed. Adjusting the motor speed can correspondingly adjust the amount of ice cutting. Generally, the more and tougher the burrs are, the higher the motor speed needs to be. The specific adjustments are determined based on actual conditions.

• Cost-saving: As carbon dioxide is a component of the atmosphere, it is easily accessible and inexpensive. The only power-consuming device is the air compressor. Dry ice directly sublimates during the cleaning process, eliminating the cost of disposing of the cleaning medium.
• Environmental Safety: CO2 is a non-toxic substance that complies with the safety requirements of the USDA/FDA/EPA. Replacing toxic chemical cleaning with dry ice cleaning fundamentally protects employees from the harm of chemical substances.
• Dry ice cleaning can be performed online, significantly reducing downtime. It avoids the need for protection, cooling, disassembly, and treatment of wastewater and sludge associated with traditional methods, saving drying time, and thus offering high production efficiency and minimal time consumption.
• Wide application range: For different cleaning conditions, simply replace the dry ice cleaning nozzle and adjust the cleaning working distance to meet various needs. The operation is simple, safe, and cost-effective, with considerable overall benefits.
• Unlike steam and high-pressure water cleaning, dry ice cleaning does not damage wires, control elements, or switches. In the food industry, dry ice cleaning greatly reduces the possibility of bacterial growth compared to water cleaning.
