Tuthill Blowers offers a wide range of blower packages, Positive Displacement Blowers and custom-designed solutions to suit the unique design requirements.
A positive displacement blower, also known as a PD blower or rotary air blower, is a machine used to transport gas or air for various purposes. Positive displacement technology is used in these systems, which capture a certain amount of air before discharging or pushing it out against the system pressure. This air usually gets pushed into a pipe or hose to transport goods or gas to a specific location.
Let's have a look at how they are helpful for different industrial purposes.
• HANDLING AND PACKAGING: Blowers can be used as an alternative to vacuum pumps in low-vacuum packing and handling uses.
• VACUUM PACKAGING: To prolong the shelf life of food items, vacuum pumps must be used in the packing process. Vacuum pumps are commonly used to collect air and remove water vapor, fat, and granular materials such as seasonings. In the chamber manufacturing stage, food is placed inside a vacuum bag and packed into a packaging compartment. The bag is heat-sealed after the air evacuates.
• THERMOFORMING: The thermoforming process is used to wrap various materials in plastic films or preformed trays. For making a container, heated plastic sheets are put over a shaping die. If the substance has cooled, it is inserted into these containers, and the upper film is heated and secured to the bottle. Thermoforming speeds up packaging efficiency significantly.
• BOTTLING: Vacuum is used to equalize friction and fluid flow throughout the bottling process. Contaminants would also need to be collected using vacuum pumps when bottling consumable drinks. Carbon dioxide is pumped into beer bottles during the bottling process to minimize the volume of oxygen within the bottle. When the bottle is filled with alcohol, the filler can also inject a tiny portion of inert gas on top of the beer, expelling the oxygen.
• PNEUMATIC TRANSPORTATION: Positive displacement blowers use in pneumatic conveying is to efficiently move dry bulk material from one location to another at different pressures and vacuum conditions. Dry bulk content is transported into a sealed pipeline containing rice, cornmeal, ingredients, whole grains, soy meal, or meat by-products within the food industry. A variety of blower models with tri-lobe rotors and specially-tuned housings are available to minimize blower noise.
