  In Zhenfei Injection Molding Machine, we have all recognized many different types of plastic dryers. If it is improperly selected, it will pay a heavy price for later use, such as low drying efficiency, high power consumption, high operating costs, low product quality, and even equipment that cannot operate normally. Therefore, if you want to manufacture high-quality and high-quality plastic products, you must choose the right equipment.

  Next, we will talk about some key points for the selection of energy-saving hopper plastic dryers for our reference, but the ideal selection depends on individual circumstances.

  1. Applicability

  First of all, it must be able to meet the basic operating requirements of plastic drying, including good material handling (feeding, conveying, hot air, heat transfer, discharge, etc.), and can achieve basic requirements such as drying effect, product quality and drying speed.

  2. Structure

  The structure of the hopper plastic dryer needs to be easy to clean without contaminating the raw materials, and the accessories need to be easy to replace and easy to buy.

  3. Drying temperature

  The drying temperature refers to the temperature of the air entering the barrel. Each raw material has a certain limit on the drying temperature due to its physical properties, such as molecular structure, specific gravity, specific heat, moisture content, and other factors. If the temperature is too high, plastic particles will be Damaged or agglomerated, too low will prevent some plastic materials from reaching the desired drying temperature.

  4. Drying time

  Drying time refers to the pre-drying time of the raw materials before molding. Too long drying time will cause damage to the raw materials or agglomeration or waste of electricity. Too short drying time will cause the phenomenon of excessive moisture content.
