The box dryer is a drying equipment used for drying plastic particles before injection molding. Before producing plastic products with high transparency requirements, plastic particles are dried to remove moisture. Using a dryer can greatly improve the quality of plastic products and avoid the generation of bubbles in the products. ONGO's Chamber Dryer delivers fast, uniform drying with precise temperature and humidity control, reduces energy consumption while protecting sensitive materials, and offers modular, low‑maintenance design for easy scaling and consistent throughput. Its inner chamber is made of food-grade stainless steel, which is corrosion-resistant, high-temperature-resistant and easy to clean, meeting the hygiene requirements of medical and food packaging plastic production. Equipped with a high-efficiency insulation layer, it reduces heat loss, and the intelligent temperature control system (40-200℃) adapts to various plastic particles, with an automatic shutdown function to save energy and ensure safe operation.
