| 1 | Multi-Zone Vibratory Fluid-Bed Dryer | Continuous food, chemical, mineral, and pharmaceutical production | 300–2,000 kg/h | 0.2–3.0% after drying | 40–120°C, adjustable by zone | 2.5–5.5 MJ/kg of water removed | Variable vibration amplitude with independently controlled drying zones; residence time commonly 5–30 minutes | Moderate; inspect springs, bearings, screens, seals, and air filters on a scheduled basis | Strong process flexibility, uniform drying, high throughput, and good heat-recovery potential | Higher purchase cost and control-system complexity; requires careful airflow balancing |
| 2 | Sanitary Vibratory Fluid-Bed Dryer | Hygienic food ingredients, nutraceuticals, and pharmaceutical intermediates | 100–1,000 kg/h | 0.1–2.0% after drying | 35–100°C | 3.0–6.0 MJ/kg of water removed | Low-amplitude conveying with adjustable air velocity; residence time commonly 3–20 minutes | Moderate to high; requires frequent cleaning, gasket inspection, screen checks, and hygienic validation | Cleanable construction, low contamination risk, and accurate control of heat-sensitive products | Sanitary finishes and cleaning systems increase capital and operating costs |
| 3 | Heat-Recovery Vibratory Dryer | Energy-conscious plants operating continuously in regions with high fuel costs | 250–1,500 kg/h | 0.5–4.0% after drying | 45–130°C | 2.0–4.5 MJ/kg of water removed | Variable vibration and airflow; residence time commonly 5–25 minutes | Moderate; heat exchangers, condensate drains, filters, fans, and insulation need routine attention | Lower fuel demand and reduced exhaust heat losses when operated near design capacity | Heat exchangers can foul, and energy savings depend strongly on feed moisture and operating load |
| 4 | Low-Temperature Vibratory Dryer with Dehumidified Air | Heat-sensitive powders, plant extracts, seeds, polymers, and specialty ingredients | 50–600 kg/h | 0.5–5.0% after drying | 25–70°C | 3.5–8.0 MJ/kg of water removed | Gentle vibration with controlled humidity and airflow; residence time commonly 10–45 minutes | Moderate; desiccant or refrigeration circuits, filters, seals, and product-contact surfaces require inspection | Protects color, aroma, potency, and other heat-sensitive product characteristics | Lower throughput and higher electrical demand than conventional hot-air systems |
| 5 | High-Temperature Vibratory Dryer | Inorganic minerals, salts, sand, ceramics, and robust industrial solids | 500–3,000 kg/h | 0.1–2.0% after drying | 100–250°C | 2.5–5.0 MJ/kg of water removed | Higher-amplitude vibration with strong airflow; residence time commonly 2–15 minutes | Moderate; high-temperature bearings, expansion joints, insulation, screens, and ducting need regular checks | Fast moisture removal, high capacity, and compatibility with rugged feed materials | Unsuitable for heat-sensitive products; thermal expansion and dust control require engineering attention |
| 6 | Compact Batch Vibratory Dryer | Pilot plants, laboratories, seasonal production, and multiple small product batches | 10–150 kg per batch | 0.2–5.0% after drying | 35–120°C | 4.0–9.0 MJ/kg of water removed | Batch vibration with manually or automatically controlled temperature and airflow | Low to moderate; simple access to screens, seals, fans, and product-contact areas | Low installation cost, flexible batch changeover, and straightforward operation | Higher labor cost per tonne and lower energy efficiency at small batch sizes |
| 7 | Heavy-Duty Vibratory Conveyor Dryer | Abrasion-resistant bulk solids and plants requiring conveying and drying in one machine | 400–2,500 kg/h | 0.5–4.0% after drying | 50–180°C | 3.0–6.5 MJ/kg of water removed | Robust vibration for controlled conveying; residence time commonly 3–20 minutes | Moderate; inspect drive components, springs, liners, screens, bearings, and dust-collection connections | Combines conveying and drying, tolerates abrasive feed, and can integrate with existing material-handling lines | May produce more noise and dust; product segregation can occur with mixed particle sizes |
