ПЭТ-кристаллизаторы - SCR
Cyclone Dust CollectorMixing definitely will bring some dust along the return air. Cyclone dust collector can remove dust in the return air
Rotary ValveWhen the return air temperature reaches to 93℃, it will send out the well crystallized PET plastics automatically. When the return air temperature is lower than 71℃, it will stop discharging
■ Features• Fixed speed of agitator makes materials not lump together during the crystallization.
• Simplify and improve drying efficiency.
• Materials can be dried under high temperature to improve drying efficiency.
• Cyclone dust collector is standard, which is applied to dust-rich place. Can effectively reduce the load on filter bag, and reduce the number of times of filter bag cleaning, thus extend the life span of the filter bag.
• With double overheat protector, it can reduce the possibility of either mechanical or man-made problems.
• Equipped with rotary valve with good sealing performance, which can output crystallized material accurately.
• Equipped with material level switch, which can detect material level accurately and make operation reliable.
• Equipped with negative pressure tester(excluding SCR-1600U) to immediately test the ventilation of the filter. Give an alarm when the negative pressure is higher than the setting value, clean the filter to avoid blockage.
■ Options• Collocate with dehumidifier to fulfill dehumidification directly.
• Safety ladder is optional(only for SCR-900U and above models).
• Auto loader, Vacuum hopper receiver are optional for material conveying.
• The optional flexible screw feeder can be added for stable and even conveying of un-crystallized material such as PET flakes.
• External pipeline is optional with the stainless steel configuration.
■ Working Principle
Once material filling starts, heat blower starts up and material heating begins. Control cabinet would stop sending signals to auto loader when material filling amount is higher than material level switch. Then material heating lasts for a while. When temperature sensing needle detects the value of reaching the set crystallized temperature, material would be conveyed out via feeding device; meanwhile, as material level in hopper lowers gradually, filling device starts to supply the uncrystallized material accordingly to realize the continuous crystallization process.
When temperature sensing needle detects the temperature value of stopping material conveying, feeding device halts. If temperature rises again to reach the set crystallized temperature, feeding device will be activated to work so that the continuous crystallization process can be realized through this kind of circle.
■ PET Property
PET material is well-used in textile fiber, food and chemical packaging. Tape stripes, industry thread, heat- resistant dishware. Air bubble and chapping will take place due to its high moisture content.
With this drying demand and the development on plastic industry, Shini provides a series of secured and reliable drying and dehumidifying technologies for PET molding and other PET product manufacturers.
Shini's PET system has great technology to meet various application needs.
• Bottle and blank making
• Thermal forming film and sheet making
• Strapping tape and industrial yams making
• Tubing making
• Waste recovery making
