Dyeing machines HIGH EFFICIENCY PRESSURE DRYER

Dyeing machines ENERGY RECOVERY HIGH PRESSURE DRYER ARSPO and ARSPV are fully-automatic yarn package dryers at high pressure (5 Bar) conceived for direct loading of dyeing carriers coming directly from dyeing machines. Bellini high-pressure dryers do not require a centrifugal hydroextraction. They are normally used for drying all possible kinds of yarns without limitations in: Fibre composition Yarn package type and size. Yarns can be cotton, acrylic, wool, polyester, rayon and blends) in form of packages (cylindrical, conical, biconical, compressible).

HIGH DRYING PERFORMANCE RAPID DRYING CYCLES ARSPO and ARSPV pressure dryers are rated for operation at HIGH STATIC PRESSURE OF 5.0 KG/CM2 in order to increase specific weight of drying air, therefore conveying a larger quantity of heat for evaporating water from the yarn under process. OPERATION IS PERFORMED IN CLOSED AIR CIRCUIT consisting of: • Autoclave designed to receive the modular yarn package carrier (s). • High-efficiency centrifugal blower. • Automatic air flow direction reversal group. • Centrifugal water drop separator. • Indirect air heating battery. • Indirect air cooling battery...

Dyeing machines THE DRYING PROCESS The complete drying operation is developed in three sequences which are performed automatically: 1 - HYDROEXTRACTION Dynamic hydroextraction replaces centrifugal operation and is done directly after loading of wet yarn carrier coming directly from dyeing machine. During this phase both heating and cooling batteries are excluded. The air is delivered at high pressure by the blower to the autoclave and passes through the yarn in outside-toinside direction. The water removed from the yarn it is collected and measured. During hydroextraction static pressure...

Dyeing machines TOP-QUALITY DRYING. AUTOMATIC CONTROL OF RESIDUAL MOISTURE. ARSPO and ARSPV pressure dryers operate efficiently with short processing times during drying at low temperature of: • White yarns and yarns dyed in pale or brilliant colour shades. • Yarns dyed with dyestuffs classes subject to migration at high temperature. Delicate yarns and heat-sensitive yarns can be dried at low temperatures in the range from 80 to 105°C with optimum quality, without yellowing effects and with perfect conservation of physical properties of handle and bulkiness. AUTOMATIC MOISTURE CONTROL SYSTEM....

OVERSIZED HEATING AND COOLING BATTERIES SPECIAL CENTRIFUGAL AIR BLOWER Loris Bellini pressure dryers are equipped with air heating and cooling batteries specially designed and tested for maximum efficiency in heat transmission. Oversized pressure rating avoids maintenance problems during long-term operation on 24 hours/day basis and deformation due to continuous heating and cooling phases. The ARSPV dryer is operated by a centrifugal blower completely made of AISI 316 stainless steel and designed for high values of head pressure and airflow delivery. Motor is installed coaxially to the blower...

Dyeing machines AUTOMATIC OPERATION The complete drying process is fully automatic. Pressurization, hydroextraction, drying, conditioning and depressurizing phases are all executed without any operator's interventions. ENERGY EFFICIENCY Loris Bellini pressure dryers are engineered for maximum energy efficiency. More than 90% of overall energy consumption, as calories consumed in heating fluid and electric power, is recovered as clean hot water to be collected and reused as process water for the dyeing process.

OPERATION IN ROBOTIZED DYEHOUSES ARSPO and ARSPV pressure dryers are in operation in several fully-robotized yarn package dyeing plants and can be supplied on request with presetting for operation in automated conditions Host-computer remote control. In order to preset optimum drying conditions for a wide range of yarn packages, fiber types and colour shades. Operation of the drying cycles can be performed by a one-touch digit of program number on the PC of the dryer. Microprocessor is designed for direct interfacing with central computer or PC for centralized dyehouse management OPTIONS...
