In the pharmaceutical, food, and health product industries, film coating is a key process for improving product stability, appearance, and functionality. Traditional coating equipment generally suffers from low efficiency, uneven coating, and high energy consumption, making it difficult to adapt to the needs of large-scale production. Changzhou Fuxing Drying specializes in the research and development of drying and coating equipment, and has launchedBGB high-efficiency film coating machineWith the core advantages of "ultra-high efficiency, precise film control, and multi scenario adaptation", we provide efficient solutions for coating processes in multiple industries, breaking the performance bottleneck of traditional equipment.
1、 Core structural design: the basic guarantee for efficient coating
The structural design of BGB high-efficiency film coating machine is optimized around the dual objectives of "efficiency improvement" and "quality control", with targeted innovation of key components:
•Large capacity tilting pot bodyAdopting 304/316L stainless steel integrated molding pot body, with a capacity covering 50L-500L (customizable), suitable for different batch production needs; The tilt angle of the pot body can be infinitely adjusted from 10 ° to 35 °, and combined with 40-80rpm variable frequency speed regulation, it ensures that the material forms a "spiral rolling" trajectory inside the pot, without accumulation or dead corners, greatly improving the contact efficiency between the material and the coating liquid.
•Multi spray gun atomization systemStandard configuration includes 3-6 high-pressure atomizing spray guns,independent control/Support synchronizationThe spray volume range is adjustable from 100-800mL/h; The spray gun adopts an anti clogging design, which can atomize the coating liquid into 3-8 μ m ultrafine droplets, evenly adhere to the surface of the material, and achieve a coating uniformity of over 99%, avoiding the problem of "local excessive thickness" in traditional single spray guns.
•Quick detachable clean chamberThe contact surface between the cavity and the material is polished with a mirror finish (roughness Ra ≤ 0.2 μ m), and there are no welding gaps; The chamber adopts a quick detachable structure, which can complete the disassembly of components such as spray guns and screens without tools. The cleaning time is reduced by 60% compared to traditional equipment, meeting the cleanliness requirements of GMP in the pharmaceutical industry and HACCP in the food industry.
2、 Core technological highlights: high efficiency, energy saving, and intelligence
•Double hot air circulation for efficient dryingInnovatively adopting a dual hot air system of "upper supply and lower exhaust+side air supplement", with precise temperature control of the inlet air temperature from 30 ℃ to 90 ℃ (temperature difference ± 0.5 ℃), and a 40% increase in hot air utilization rate; Combined with the insulation design of the pot interlayer, the coating time for a single batch is reduced by 30% -40% compared to traditional equipment. Taking 100000 ordinary tablets as an example, the coating time can be compressed from 4 hours to 2.5 hours.
•Energy saving design for waste heat recoveryEquipped with an efficient waste heat recovery device, 40% of the heat in the exhaust can be recovered for preheating fresh air, reducing comprehensive energy consumption by more than 25%; At the same time, the equipment adopts a variable frequency motor, and the no-load energy consumption is only 50% of that of traditional equipment. Long term use can significantly reduce the operating costs of enterprises.
•PLC intelligent control systemEquipped with a 7-inch touch screen PLC system, it can preset more than 80 sets of coating formulas (including temperature, speed, spray volume and other parameters), support one click start and parameter memory; The system has real-time data monitoring and abnormal alarm functions (such as temperature exceeding the standard, spray blockage), and can export production data reports to meet the traceability needs of multiple industries.
3、 Multi domain adaptation application
•pharmaceutical industryUsed for enteric/gastric coating of tablets and microspheres, such as aspirin enteric coated tablets and probiotic microsphere coating. Precise temperature control and clean design ensure drug compliance, with solvent residue ≤ 0.3%.
•food industrySuitable for thin film coating of candies and nuts (such as chocolate bean gloss coating and nut moisture-proof coating), efficient drying to avoid material softening, ensuring product taste and shelf life.
•Health Products IndustryUsed for coating vitamin tablets and protein powder particles, ultra-fine atomization technology can achieve "thin coating with high coverage", reduce the amount of coating solution used, and lower production costs.
