Four double-cone rotary vacuum dryers are all ready for shipment! Haihan Drying welcomes a small peak of shipments during the Spring Festival

As spring is getting stronger, the momentum is at its peak. On March 12th, the production workshop of Changzhou Haihan Drying Equipment Technology Co., Ltd. presented a busy scene: four brand-new SZG series double-cone rotary vacuum dryers were neatly arranged. After undergoing multiple factory processes such as deburring, fine polishing, and clean cleaning, they successfully completed quality inspection and packaging. Then, with the coordinated operation of lifting equipment, they were steadily loaded onto the truck and were about to be shipped to the customer's production site. The simultaneous shipment of these four devices on the same day marks the full release of Haihan Drying's production capacity in the new spring, and also demonstrates the high recognition of the company's products by the market.
Strict quality inspection to ensure high-quality delivery
As a professional manufacturer of drying equipment, Haihan Drying always regards product quality as the lifeline of the enterprise. The four double-cone rotary vacuum dryers dispatched this time have undergone rigorous no-load trial runs, vacuum pressure maintenance tests, and jacket pressure inspections before leaving the factory. Technicians conducted meticulous inspections on every weld seam and sealing point to ensure that all performance indicators of the equipment exceed the design standards.
"The four equipment units ordered by the customer will be used for drying fine chemical materials, and they have extremely high requirements for equipment cleanliness and vacuum stability," said the on-site quality inspection leader. "We strictly follow GMP standards for surface treatment and cleaning operations to ensure that the equipment can be quickly put into use upon arrival at the factory.". ”
Technological innovation empowers customers with efficient production
The SZG double-cone rotary vacuum dryer, developed by Haihan Drying based on the absorption of advanced technologies from both domestic and international sources, represents a new generation of drying equipment. It integrates mixing and drying functions and is widely used for drying powdered and granular materials in industries such as pharmaceuticals, chemicals, food, and dyes.
The equipment utilizes a double-cone rotating tank, which is heated by heat-conducting oil or hot water within the jacket under vacuum. The heat fully contacts the material through the inner wall of the tank. The slow rotation of the tank continuously turns the material up and down and inside out, greatly accelerating the drying rate and ensuring uniform and thorough drying of the material. For heat-sensitive, easily oxidizable, and solvent-recyclable materials, this equipment has irreplaceable advantages.
Customized services to meet diverse needs
As a high-tech enterprise, Haihan Drying has been deeply involved in the field of drying equipment for many years, established a high-level R&D team, and achieved multiple breakthroughs in intelligent drying, energy-saving and environmental protection technologies. The company can provide a variety of heating options ranging from high-temperature heat transfer oil to low-temperature hot water, as well as personalized customization services such as glass-lined interior, stepless speed regulation, and pressure vessel certificates, based on customer material characteristics and process requirements.
"For the four devices shipped this time, we have conducted targeted optimization design based on the material characteristics of our customers, ensuring that they can meet current production needs while also leaving room for future process upgrades," said the sales manager. "Shipping is just the starting point. We will also provide installation and debugging guidance as well as lifelong technical support in the future."
