Zhengzhou Fusmar Machinery is a professional cooling machine manufacturer, this article we will introduce SZLH series counter flow cooler in detail.

Application Of Counter Flow Cooler

Mainly applicable to a variety of granular material cooling. Cooling machine achieves refrigeration by vapor compression or absorption cycles. These liquids can flow through the heat exchanger to cool the air or equipment.

The vapor compression cooler consists of four main components of a vapor compression refrigeration cycle (such as compressor, evaporator, condenser, part metering device). Otherwise,  the machine can realize different refrigerants, the refrigerant used in the absorption refrigerator and the benign silica gel used in the city as a desiccant.

Livestock Poultry Feed Production Line

  1. 10-80 t/h pig feed production line
  2. 10-20 t/h suckling pig feed production line
  3. 10-80 t/h chicken feed production line
  4. 10-80 t/h duck feed, goose feed production line
  5. 10-60 t/h rabbit feed production line

Main Product Characteristics

  1. This machine adopts the counter flow cooling principle to cool down pellets with high temperature and high moisture content. This cooling method can avoid the sudden cooling. Because of the direct contact between the cold air and materials, which will prevent the surface cracking of the pellets.
  2. The latest design of octagonal cooling chamber has no dead angle.
  3. Feeding via airlock has large wind area and remarkable cooling effect.
  4. The reciprocating slide valve discharging mechanism is stable, and then reliable in working and guarantee less residue.
  5. Low energy consumption and easy operation.
  6. The temperature of cooled products is not 3℃ to 5℃ higher than room temperature. Which is suitable for cooling granule materials.
  7. We also provide cooler with panel turnover discharging system for your choice. The hydraulic driven discharging mechanism is usually used for cooling the extruded of expanded materials.

Counter Flow Cooler Working Principle

The dried wet material is sent to the hopper by a belt conveyor or a bucket elevator, and then fed through the hopper through the feeding pipe into the feeding end. The slope of the feeding pipe is greater than the natural inclination of the material. So that the material flows smoothly into the cooler. The cooler cylinder is a rotating cylinder that is slightly inclined to the horizontal.

The material is added from the higher end, the heat carrier is discharged from the lower end, and is in counter contact with the material. The heat carrier and the material are simultaneously flowed into the cylinder. As the rotating material of the cylinder is moved by gravity to the lower end. During the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained. So that the hot material is cooled, and then sent out at the discharge end through a belt conveyor or a screw conveyor.

A copy board is arranged on the inner wall of the cylinder, and its function is to copy and sprinkle the material. So that the contact surface of the material and the air flow is increased. And then increase the cooling rate and promote the advancement of the material. The cooling body is generally classified into cold air or the like. After the heat carrier passes through the feed cooling machine, a cyclone is generally required to trap the material contained in the gas. If you want to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or the wet dust collector.

Advantages Of Counter Flow Cooler

  1. Counterflow cooler has low air consumption.
  2. The temperature difference between pellets and cold air decrease to the minute.
  3. The discharging system of counter flow cooler ensure pellets distribute uniform.
