SGL70-I
The SGL70-I intelligent double layer dehumidification rotary cage dryer is a supporting equipment for soft capsule production lines, developed based on years of soft capsule drying process experience. It integrates dehumidification and drying functions, and is used for the post-forming drying process of soft capsules. The equipment adopts a segmented rotary cage structure with independent temperature and humidity control, which can shorten the drying cycle of soft capsules and reduce appearance defects of finished products. It is suitable for pharmaceutical manufacturing plants, health supplement producers and other industrial clients with soft capsule drying demands, and can be matched with various models of soft capsule machines.
The drying effect directly affects the appearance quality, storage stability and production efficiency of soft capsules. The SGL70-I model optimizes the drying efficiency and uniformity from three dimensions: humidity control, temperature control and air circulation.
The equipment is equipped with a dehumidification system with large processing capacity, which can control the minimum humidity inside the rotary cage within 8%. The low-humidity internal environment accelerates the evaporation of water from the soft capsule skin, greatly shortening the drying cycle compared with ordinary drying equipment. For production lines with large output, the shortened drying cycle can reduce the backlog of semi-finished products, improve the turnover efficiency of the entire production line, and reduce the occupation of production space by semi-finished products. The dehumidification system operates stably during the drying process, maintaining the set humidity range in each section of the rotary cage to avoid fluctuations in drying effect caused by environmental humidity changes.
The equipment is equipped with a refrigeration unit, which can control the internal temperature of the entire rotary cage and adjust the temperature according to the drying requirements of different types of capsules. This temperature controllability ensures that capsules with different gelatin formulas and content properties can be dried at a suitable temperature, avoiding problems such as capsule deformation or content deterioration caused by inappropriate temperature. In addition, the equipment is equipped with a large-air-volume fan system, which greatly increases the number of air circulation cycles inside the rotary cage. Each section of the rotary cage is configured with two centrifugal fans, which form an air circulation system with the fan inside the dehumidifier to take away the water evaporated from the capsule skin in time and ensure uniform drying of capsules at different positions in the rotary cage.
For production scenarios in pharmaceutical and food industries, the material compliance and operational flexibility of drying equipment are core concerns for commercial procurement. The SGL70-I model has corresponding designs in material selection and control modes.
All covering parts and capsule-contact parts of the equipment are made of stainless steel that conforms to GMP requirements. This material selection meets the hygiene standards of pharmaceutical and food production, avoids material pollution to capsules during the drying process, and supports regular cleaning and disinfection operations. The stainless steel structure also improves the corrosion resistance of the equipment, prolongs the service life in high-humidity working environments, and reduces the frequency of part replacement.
The equipment adopts a segmented rotary cage design, and the capsules complete the drying process through multiple sections in turn. The temperature and humidity of each section can be controlled independently, which can set gradient drying parameters according to the water loss law of the capsule skin, improving the drying effect and reducing the probability of capsule surface defects. The control system supports two modes: automatic control and manual control. In automatic mode, the equipment operates according to the set process parameters, and the capsules automatically transfer to the next section after reaching the set drying time. In manual mode, operators can adjust important parameters such as temperature, humidity and drying time according to actual production conditions, adapting to trial production of new products and special process requirements.
The soft capsules produced by the soft capsule machine enter the first section of the rotary cage through the high-pressure air supply system. After running for the set time in the first section, the capsules are transferred to the next section in turn until they complete the drying process of all sections. During the operation of the equipment, the temperature and humidity in each section of the rotary cage are regulated by the refrigeration unit and dehumidification system respectively, maintaining the set process parameters. The centrifugal fans in each section and the fan inside the dehumidifier form a closed air circulation system, which continuously takes away the water in the soft capsule skin and discharges the moist air out of the system through the dehumidification device. The entire drying process can be monitored through the control system, and the operating status and parameter data of each section can be viewed in real time.

This rotary cage dryer is mainly used in the soft capsule production process, and can be adapted to the drying needs of different types of soft capsules. In the pharmaceutical industry, it can be used for drying medicinal soft capsules, meeting the requirements of pharmaceutical production for drying environment hygiene and product quality consistency. In the health supplement industry, it is suitable for drying various nutritional soft capsules such as fish oil capsules and vitamin capsules, shortening the production cycle and improving the appearance consistency of finished products. The equipment can also be used for drying other gelatin-coated products that require low-humidity and temperature-controlled drying environments, with certain process adaptability.
The equipment supports temperature adjustment, and can set different drying temperatures and humidity parameters according to the gelatin formula, content type and size of soft capsules. It is suitable for most conventional soft capsule products. For special formula capsules, process verification can be carried out before formal use.
The equipment is equipped with two control modes: automatic and manual. In manual mode, operators can adjust core parameters such as temperature, humidity and drying time of each section according to actual production needs, adapting to different process requirements.
All parts that come into contact with capsules during the drying process are made of stainless steel that conforms to GMP requirements, which meets the hygiene standards of pharmaceutical and food production.
The equipment reduces the internal humidity of the rotary cage to within 8% through the dehumidification system, and cooperates with a large-air-volume circulation system to accelerate the evaporation of water from the capsule skin, thus shortening the overall drying cycle.
The SGL70-I double layer dehumidification rotary cage dryer provides a stable drying solution for soft capsule production. With controllable temperature and humidity, segmented drying design and GMP-compliant material structure, it can meet the drying process requirements of different products and improve the production efficiency and finished product quality of soft capsule production lines. For industrial clients planning to build new soft capsule production lines or upgrade existing drying equipment, this model can be matched with mainstream soft capsule machines to realize the connection of the production process.
