■ Weighing/Mixing hopper incorporated

A compact hopper for weighing and mixing virgin and crushed resin is assembled into the dryer for primary loading. Virgin and crushed resin are alternately fed to the scale via a branch valve and weighed as they pass a proximity switch. Resin is then mixed by screw rotation. Mixing ratios are freely and easily set by button operation, and the scale and mixer are enclosed in a glass tube so that mixing consistency can be easily checked. Moreover, the hopper can be attached to the dryer or separated for standalone operation, and the mechanical structure makes it easy to maintain.

■ Switchable between Normal Mode and Energy-saving Mode

The NS series dryer can switch between a Normal Mode that provides high efficiency resin drying and an Energy-saving Mode” that reduces dehumidifying air injection rate by about 40%. This enables users to match operating efficiency to resin characteristics, as the “normal mode” can be used for engineering plastics and other resins that require thorough drying, and the “energy-saving mode” can be used for general-purpose resins, etc.

■ Stock feeding to 2 -- 4 molding machines

The NS series can supply dried resin stock to 2 -- 4 molding machines using multiple feed branch lines and air branch valves.

■ Higher powered blower

Feed blower capacity can be increased if the standard dryer has trouble supplying molding machines because of longer conveying distances or heavy resin weights.
Not applicable the NS-10G and NS-15G.
The standard conveying distance is given for one-way suction of PC over a STOLZ hose.

■ 2-stock suction valve  ZB-13

Two types of stock such as virgin material and crushed material can be simultaneously loaded into the same dryer using the ZB-13 branched suction valve. And, the ZB-13 can be externally connected to a dedicated independent controller. This makes it easier to monitor suction status, etc.

■ Low stock level gauge

Material depletion in the drying drum caused by trouble in dryer feed (primary loading) is signaled by a buzzer and warning lamp (ordered separately). See “Warning lamp” to choose a warning lamp.

■ Line filter  GF-20-002, GF-25-002

A line filter can be installed on the molding machine hopper to thoroughly remove dust. Applicable models are GF-20-002 and GF25-002. The GF25-002 incorporates powerful magnets for removing even iron dust.

■ Hopper plate and attachment for installation on molding machine

An installation plate and attachment are separately needed to install the hopper on molding machines that do not meet the standard specifications shown in the table, therefore indicate those specifications when ordering.
