300kg SS Dryer Hopper PP Line
Product Overview
Stable raw material supply is the lifeline of continuous production. This production line is equipped with a 300kg 304 stainless steel dryer hopper with an integrated automatic feeding device. The hopper has a built-in hot air drying module with adjustable temperature from 0-120°C and drying power of 12KW, ensuring PP material moisture content ≤0.1%, eliminating bubbles and silver streaks from the source.
The 300kg large capacity means that at maximum output, a single fill supports about 1.25 hours of continuous production; combined with automatic feeding, truly uninterrupted operation is achieved. 304 stainless steel is corrosion-resistant, easy to clean, and rust-free over long-term use, ensuring raw material purity.

Frequently Asked Questions
Q: How long can a full 300kg hopper run?
A: At maximum output of 240 kg/h, a full hopper lasts about 1.25 hours. The automatic feeder continuously replenishes, enabling truly uninterrupted production.
Q: What is the recommended drying temperature?
A: For standard PP, 80-100°C is recommended. The drying function must run continuously because even initially dry material absorbs moisture in the workshop environment. Turning off drying leads to moisture-related defects.
Q: Does the hopper need regular cleaning?
A: Cleaning is recommended every 200-300 tons of production or when switching colors/modified materials. A discharge port at the bottom facilitates removal of residual material.
