Hot Air Dryer Machine
hot air dryer machine
The drying machines are mainly used in the automatic packaging lines of beverages, beer, pharmaceuticals, cosmetics, wine, red wine, etc. They are also applicable to various containers such as bottles, cups, cans, bowls, etc., and can be directly connected in series with your steam tunnels or production lines. Hot air enters the high-pressure blower through a filter and then passes through pipes to the air outlet. The air-drying device blows the wind power to the air knife by the blower, and the air knife evenly blows the air onto the bottles. Since the air knife opening has a long slit only 0.5mm wide, the blown-out wind is quite strong and can evenly and effectively dry the moisture on the bottle body.
Working Principle of Hot Air Dryer Machine
High-speed centrifugal blower
It uses a high-speed centrifugal blower to generate a powerful air current. After the blower sucks in the air, it accelerates the air through a specially designed impeller, making the air current obtain a higher speed and pressure, thus forming a high-speed air curtain.
Heating device
The air current passes through a heating device. The heating element (usually a stainless steel heating tube) heats the air current, and the heating temperature can be precisely controlled, generally adjustable between 30°C and 80°C to meet the drying requirements of different product packaging materials. The heated hot air can accelerate the evaporation of moisture or other liquids on the product surface.
Hot air spray evenly
The hot air is evenly sprayed onto the surface of the packaged products through specially designed air nozzles or air ducts. The shape, number, and arrangement of the air nozzles are optimized to ensure that the hot air can fully cover all parts of the product, such as the bottle body, bottle cap, label, etc., making the drying effect uniform and avoiding local residual moisture.
Structural Features of Hot Air Dryer Machine
The body of the machine is made of stainless steel. Considering its application in the food, pharmaceutical, and cosmetic industries, the stainless steel body has good corrosion resistance, is easy to clean and disinfect, meets the requirements of hygiene standards, and prevents rusting or other impurities from contaminating the products.
The adjustable air nozzle assembly. The angle, direction, and distance of the air nozzles from the products can be flexibly adjusted to adapt to different shapes and sizes of packaging bottles, cans, boxes, etc. For example, for cylindrical beverage bottles and square cosmetic packaging boxes, the air nozzles can be adjusted to achieve the best drying effect without causing damage or displacement to the products.
An efficient filtering system. It is equipped with an air filter to filter out tiny particles such as dust and impurities from the air entering the blower, ensuring that the blown-out hot air is pure and pollution-free, avoiding secondary pollution on the product surface during the drying process, which is especially important for the pharmaceutical and cosmetic industries.
An intelligent control system. It has advanced functions of controlling temperature, wind speed, and time. Operators can precisely set the corresponding parameters on the control panel according to the drying requirements of different products. The control system will automatically adjust the rotation speed of the blower, heating power, etc., ensuring a stable and reliable drying process. At the same time, it can also monitor the running status of the equipment in real time, and will give an alarm prompt if there is any abnormality.
Different Industry Packaging Lines
Application Advantages of the Drying Machine in Different Industry Packaging Lines
Beverage Industry
For beverages packaged in glass bottles or plastic bottles, such as soda and fruit juice, it can quickly remove the moisture remaining on the bottle body surface during the bottle washing or labeling process, preventing the label from curling up, getting moldy, or breeding bacteria after packaging, which affects the appearance and quality of the product and ensures a good display effect and quality stability during the shelf life of the product.
01
Beer Industry
After beer bottles are recycled and cleaned, there are often some residual moisture. The drying machine can thoroughly dry the inside and outside of the bottle body, preventing the moisture from contacting the beer and affecting the taste and quality, and also avoiding the breeding of microorganisms due to residual moisture, ensuring the freshness and hygiene safety of the beer. In addition, for beer aluminum cans, the drying treatment can make the can body surface bright and clean, enhancing the overall image of the product.
02
Pharmaceutical Industry
During the drug packaging process, whether it is drug bottles, drug boxes, or blister packaging, etc., the hygiene requirements are extremely high. The drying machine can remove any moisture, solvents, or other impurities that may exist on the surface of the packaging materials, ensuring the cleanliness of the drug packaging, reducing the risk of drug contamination, and thus ensuring the safety of patients using the drugs. For example, for the drying of injection glass bottles, it can prevent the moisture from affecting the stability and efficacy of the drugs, and also avoid the quality problems of drugs caused by microbial contamination.
03
Cosmetic Industry
Most of the cosmetic packaging is in the form of delicate glass bottles, plastic bottles, or paper boxes, with requirements for a beautiful and hygienic appearance. The drying machine can quickly dry the packaging surface, making the label stick firmly and flatly, preventing the moisture from causing the label to be blurred or fall off, which affects the brand image of the product. At the same as this, for some cosmetics containing active ingredients, a dry packaging environment helps to maintain the activity and quality stability of the products, prolonging the product shelf life.
04
Wine and Red Wine Industry
Wine bottles are usually glass bottles, and they are prone to get wet during the cleaning, filling, and labeling processes. The drying machine can gently and effectively remove the moisture on the bottle body and bottle label, avoiding the contact between the moisture and the wine liquid during storage, preventing the damage, getting moldy of the bottle label, and the influence on the quality of the wine liquid, ensuring the quality and appearance image of the wine during the aging and sales processes.

Maintenance and Care Points of Hot Air Dryer Machine
Regular cleaning. After each use, the power of the equipment should be turned off. After the equipment cools down, clean the dust, debris on the surface of the machine body, as well as the dirt on the air nozzles and filters. You can use a wet cloth to wipe the machine body, but avoid water getting into the electrical components. For the filters, they should be disassembled, cleaned or replaced according to the specified cycle (such as weekly or monthly, depending on the use environment) to ensure the filtering effect.
Fan maintenance. Regularly check the wear condition of the impeller, bearings and other components of the fan. If there is any abnormality, replace them in time. Add an appropriate amount of lubricating oil to the bearings of the fan to ensure that the fan runs smoothly and the noise is normal. Generally, a comprehensive inspection and maintenance of the fan are carried out every 3 to 6 months.
Heating element inspection. Regularly check the working state of the heating tubes, and see if there is any situation of uneven heating or damage. If you find obvious discoloration, deformation or non-heating problems on the surface of the heating tubes, replace them in time to ensure the heating performance of the drying machine.
Calibration and debugging. Every once in a while (such as every half year or year), use professional instruments to calibrate the temperature, wind speed and other parameters of the drying machine to ensure that the performance of the equipment meets the production requirements. At the same time, when replacing different product packagings or adjusting the production process, the equipment also needs to be debugged accordingly to optimize the drying effect.
