Vibration coolers mainly use vibration and forced airflow to quickly cool high-temperature materials. In this process, they can disperse and transport materials to subsequent processing and packaging equipment. They are widely used in food, feed, medicine and other industries, and are key auxiliary machines for subsequent processing, packaging and storage.
Vibrating cooler is a special equipment that uses the material dispersion effect generated by vibration and the heat exchange effect of cold air to cool, convey and preliminarily screen high-temperature solid materials. The core function is to cool the material and remove surface moisture to prevent mildew and ensure storage quality.
Vibrating air coolers can be installed in animal feed production lines and small and medium-sized food processing plants:
1.Installed and used downstream of animal feed pellet machines or single-screw extruders to cool high-temperature pellet feed, reduce moisture content to meet storage requirements, avoid agglomeration during storage, and maintain pellet hardness and integrity.
2.Supporting extruded food production lines, cooling directly after extrusion to ensure product crispness and prevent products from softening, deforming or mildewing due to high temperature.
1. Vibrating conveying system: The material is made to jump in the trough through vibration to avoid agglomeration, and the thrust of vibration can be used to move the material to the outlet.
2. Cooling air system: Provide clean cold air to the material, form a hot and cold air exchange, and take away the evaporated moisture on the surface of the material, and reduce the moisture content.
3. Frame and shock absorption system: The rigid frame can fix the vibration conveying and cold air system, and the shock absorption device reduces the noise transmitted to the ground by the vibration generated by the vibration motor.
4. Drive system: The periodic vibration of the vibration motor and the control of the vibration frequency of the motor speed regulator are matched with each other, so that the residence time and transmission speed of the material can be adapted to the cooling needs of different materials.
5. Control system: The temperature sensor can detect the outlet temperature of the material in real time, and the PLC control cabinet can realize abnormal alarm of the machine to improve safety.

Feeding stage: High-temperature materials enter the conveying trough from the upstream equipment, and the vibration motor is started again. The materials jump forward under the action of inertia and are initially dispersed.
Cooling and heat exchange stage: The fan delivers cold air, which passes through the material layer and contacts the surface of the high-temperature material to exchange heat and take away moisture.
Conveying and discharging stage: Under the thrust of vibration, the cooled material continues to move forward and is finally discharged from the end and enters the next process.
1.High cooling uniformity: Vibration fully disperses the material to avoid accumulation
2.Simple structure and easy maintenance: No complex transmission parts, simple disassembly and assembly of core parts, easy daily maintenance
3.Little material damage: Vibration conveying is a flexible contact, with little extrusion friction on the material, which can maintain the integrity of granular and block products
4.Low energy consumption and cost: The fan power is usually 1.5-5kW, and the equipment purchase cost is low
5.Wide range of applications: It can handle various forms of materials such as granules, blocks, and strips. By adjusting the vibration parameters and air volume, it can adapt to different product requirements such as puffed food, feed, and pharmaceutical granules.
