Import Counterflow Cooler — Buy in Bulk from Supplier in China

Lambton Machinery (Zhengzhou) Ltd. manufactures counterflow coolers designed to reduce the temperature of processed pellets by exposing them to an upward stream of ambient air. The cooling process relies on blowing air through columns of hot, moist pellets, which evaporates moisture and extracts heat, lowering the pellet temperature to within 5-10°F of ambient conditions. This method minimizes temperature shock, a common issue in rapid cooling systems, and reduces stress and fines in the final product.

The cooler operates on the principle of counterflow, where the product and air move in opposite directions, enabling gradual and uniform heat transfer. Key design options include rectangular, square, or circular cooling chambers, with the circular design offering superior pellet distribution and eliminating dead zones in corners. The system’s efficiency is influenced by air pressure, volumetric flow rate, column length, and residence time, all of which can be adjusted to meet specific cooling requirements.

These coolers are widely used in feed processing and pelletizing industries, where consistent product quality and moisture control are essential. The discharge mechanism features a slide valve for adjustable, smooth product flow, and a probe level sensor monitors material levels. Typical applications include animal feed production, where maintaining pellet integrity and nutritional value is critical for end users.

Lambton Machinery (Zhengzhou) Ltd. is located in Zhengzhou, Henan Province, China, with its address at 150 Lamei Rd. in the High-Tech Development Zone. The company specializes in feed processing equipment, including counterflow coolers, which are designed to enhance product quality and operational efficiency in industrial settings.
