Fluidized Thermal Sand Bed Cleaning

Fluidized Sand Bed Stripping in the Midwest

Winona operates one of only a few Dinamec Fluid Systems sand strippers located in the Midwest that is available to outside companies with parts, racks, or mold cleaning needs. In addition to utilizing the system for our internal needs, we sell this valuable service. Winona specializes in performing all our services in a timely manner, and this process is no different. We can even arrange for parts to be stripped and cleaned the same day, so downtime is minimized for our customers.

How Does the Process Work?

The fluidized bed reactor contains calibrated sand in a liquid-like state (suspended sand particles). The reactor is heated to a steady temperature in the range of 420–450°C. In this condition, the sand becomes a powerful reactor, in which a fast and complex physiochemical process will evaporate and oxidize any organic material.

Once the sand has reached the optimal temperature, parts needing to be cleaned are submerged in the fluid bed reactor. In the first phase, which takes 10-20 minutes, light organic compounds and binders quickly evaporate due to the intense contact with the hot silica sand. They are extensively oxidized at relatively low temperatures to harmless inert gas.

Remaining heavier hydrocarbons are completely oxidized within the reactor, while the inert portion of the contamination is blown out of the reactor as all organic binders have vanished. During the second phase, a light mechanical cleaning action caused by the bubbling sand will sustain it. After an average of one hour, the two-phase cleaning process is finished: the organic fraction is eliminated, and the inert fraction is blown out of the reactor with the exhaust gases.

Contact Winona Powder Coating

Modern coatings and plastic bond very strongly, and traditional cleaning and stripping methods are becoming outdated. They demand costly labor and energy as well as possible health hazards for the operators. These conventional methods often damage or deform parts and can result in water and air pollution.

Today almost every industry is involved with organic substances such as paint, powder coating, plastic, or rubber at some stage of its production process.

Removing plastic or paint coatings from metal parts, finished products, or production components made of metal is a widespread problem. Let Winona be the solution!
