GOORUI side channel blowers are mainly used in food packaging equipment for key applications such as material conveying, positioning and fixation, thermoforming and carton forming, sealing and labeling, dust removal and cleaning, environmental control, gas filling packaging and vacuum treatment. They feature high efficiency, energy conservation and hygiene.
Material conveying: The high-pressure side channel blower conveys powdery or granular materials (such as flour, sugar powder, coffee powder) from the storage tank to the hopper of the packaging machine through the pneumatic conveying system, using positive or negative pressure. For instance, in chocolate production, high-pressure side channel blowers convey cocoa powder to the packaging line at an efficiency of 5 tons per hour, with a dust leakage rate of less than 0.1%. At the same time, it avoids direct contact between the material and mechanical components, reducing the risk of contamination.
Positioning and fixation: In bottle and canning production lines, the airflow generated by high-pressure side channel blowers can blow away the residual materials at the bottle mouths, ensuring filling accuracy. For instance, by using pneumatic fixtures to fix containers, the positioning accuracy can reach ±0.1mm, enhancing the consistency of filling. In addition, during the labeling process, the negative pressure generated by the fan adsorbs the label paper, making it adhere to the surface of the container and avoiding bubbles or wrinkles. The labeling accuracy can reach ±0.5mm, and the label application qualification rate has increased from 95% to 99.8%.
Thermoforming and paper box forming: During the thermoforming process of plastic films, high-pressure side channel blowers use blow molding technology to expand the heated film into the shape of a mold, forming packaging containers (such as cups and boxes). Its high-pressure airflow can ensure that the film adheres evenly to the mold, avoiding damage caused by uneven thickness. In the paper box folding machine, the fan drives the cylinder to push the cardboard to fold, and at the same time, the nozzle blows air to assist in shaping, making the structure of the paper box stable and reducing the deformation rate.
Sealing and labeling: In the process of sealing cartons or aluminum foil bags, high-pressure side channel blowers provide compressed air to the hot melt glue gun to ensure uniform spraying of the glue and accelerate curing through air flow cooling, thereby enhancing the sealing strength. For instance, in an aluminum foil sealing machine, the fan generates a vacuum to make the heat-sealing film closely adhere to the container opening, raising the sealing qualification rate to 99.9% and meeting GMP requirements.
Dust removal and cleaning: Before packaging, the high-pressure side channel blower blows off the dust or debris on the surface of the product (such as glass bottles and metal cans) through nozzles to ensure the cleanliness of the packaging appearance. For instance, before beverage filling, the fan blows away foreign objects from the bottles and dries them quickly to ensure that the labels are firmly adhered, reducing the defective labeling rate from 3% to 0.5%. In addition, when the packaging line is changed, the fan can quickly blow away the residual materials in the equipment, reducing downtime and improving production efficiency.
Environmental control: High-pressure side channel blowers are used in conjunction with air conditioning systems to maintain a constant temperature (22-25℃) and low humidity (≤50%) in the workshop, preventing temperature-sensitive foods such as chocolate from melting or frosting. Meanwhile, the fan can be used to circulate air, remove harmful gases and odors, and create a comfortable working environment. For instance, in the processing of fried food, the fan sucks the cooking fumes into the electrostatic oil removal device, achieving a purification efficiency of over 95%. The concentration of cooking fumes in the workshop has dropped from 15mg/m³ to 0.8mg/m³, meeting the national emission standards.
Inflatable packaging and vacuum treatment: In the packaging of easily oxidized foods such as nuts and coffee, high-pressure side channel blowers are used to fill nitrogen to displace air, thereby extending the shelf life. For instance, in the processing of preserved fruits, the fan’s vacuuming enables the sugar solution to quickly penetrate the fruit flesh, shortening the soaking time. The production cycle is reduced from 72 hours to 24 hours, and the sugar uniformity is increased by 40%. In addition, the fan can also work in coordination with the vacuum pump to quickly remove water from fruits and vegetables at low temperatures while retaining nutrients. The retention rate of vitamin C is over 90%.
