Description

Technical Field

[0001] The utility model relates to the technical field of tobacco drying equipment, in particular to a drum dryer receiving device and a dryer containing the same. Background Art

[0002] Popping beads for cigarettes, commonly known as capsules or scented beads, are 1.5 to 6.5 mm in diameter and are spherical objects made of edible gum. They contain a special scented liquid made from essences, spices, Chinese herbal extracts, and an appropriate amount of solvent. Adding popping beads to cigarettes is a flavor-compensating technology for cigarette flavoring. Adding contents of different properties to popping beads can enrich the aroma of cigarettes, improve the taste of cigarettes, and reduce harmful components in cigarettes. As a new flavoring technology for cigarettes, "popping bead addition" has become an important technical means to build cigarette products with flavor shaping as the core. Therefore, in recent years, with the rapid development of popping bead cigarettes in domestic and foreign markets, tobacco companies' demand for popping bead production has continued to increase.

[0003] The most common method for industrializing the preparation of popping beads is the concentric film-forming method. The concentric nozzles of the dropper spray machine spray the wall material solution and the core material solution at different speeds. The wall material wraps a certain amount of the core material and is then dripped into another immiscible coolant to solidify and form. After subsequent solidification, cleaning, drying, and screening processes, the finished popping beads are finally produced. Current drying methods mainly include natural air drying and drum drying. Because the popping bead wall material and core material are both formed from liquid, the wet pellets are soft before drying. During the drum drying process, their shape and fluidization state are difficult to control, which can easily result in the popping beads being elliptical, convex, hemispherical, and other irregular shapes. This reduces product quality and production efficiency.

[0004] The wet pellets of the popping beads are fluidized and dried in a rotating drum, and the moisture in the wet pellets is removed through heat exchange between the air and the wet pellets. The air flow in the rotary drum drying technology of the popping beads is one of the key factors to achieve an efficient drying process. A collecting device is provided inside the drum. During the drying process, when the drum is running and reaches the low position of the air duct outlet, it is in a leeward position from the wind and cannot be blown by the wind, causing the wet pellets of the popping beads to stick to this position. This part of the wet pellets of the popping beads cannot be dried, resulting in a decrease in the qualified rate of the product and also generating a certain amount of workload for other selection processes. Therefore, how to provide a rotary drum collecting device that can ensure that the drying effect of the popping beads meets the requirements when discharging is a technical problem that needs to be solved urgently by those skilled in the art.
