"Standard" Hopper Dryers - SHD

Inquiry Buy Now
SHD series “Standard” hopper dryers offer an effective and low-cost method for plastic material drying. Hot air is used to dry wet materials that due to moisture absorption during packaging, transportation, and recycling cycles. They can be directly mounted on the moulding machine for quick drying and space saving. For this series, hot air blows evenly from bottom to the top (both SHD-800 and SHD-1000 have down-blowing air pipe and accessible door for easy material clearance) of the hopper with capacity ranging from 12~1,000kg, standard equipped with RS485 communicating function.

Features

  • The max. drying temperature can reach up to 160℃.
  • Adopt hot air diffuser to gain an even hot air flow to improve drying efficiency.
  • Unique hot air inlet elbow design can prevent dust piling up at bottom of the pipe heaters so as to avoid burning.
  • All material contact surfaces are made of stainless steel to eliminate material contamination.
  • Hopper separated from its base, ensuring convenient cleaning.
  • Controller with LCD display to display and being controlled conveniently .
  • All series are equipped with exposed power switch.
  • Equipped with excitation tripping overheat protection, making machine operation secure and reliable.
  • For SHD-25~150, heater pipes are connected by aluminum sheets and other models are equipped with temperature protection to prevent heater pipe from damaging by blower faults.
  • Overheat tripping can automatically cut off power when drying temperature exceeds set deviation value.
  • Adopt heat-insulated blower to prolong blower lifespan. 24 hours auto start/stop timer and double insulated hopper are available as options.
  • Cyclone dust separator, exhaust air filter, magnetic base and blower inlet filter are optional.
  • Hot air recycler, suction box, hopper magnetic, N type floor stand and storage hopper are optional.

Working Principle

Ambient air is blown into drying hopper after heated by heater pipe. Hot air is distributed evenly via shade or screen separator over the material. Moisture in the material is removed slowly over time. Hot air recycler is optional so the air enters drying blower after being filtered to form a closed loop circle and save electricity

Application

SHD hopper dryers are used for drying hygroscopic plastics, such as PS, PP, and ABS etc., which can reach the highest drying temperature up to 160 C . The double- layer insulation models can offer uniform drying temperature with less heat loss. In addition, multiple accessories are optional to realize different functions, such as recycling hot air and filtering metal impurities in the materials. The floor stand makes machine floor mount available
