KY-65 Co-Rotating Parallel Twin Screw Extruder Machine Group （L/D=20）

Introduction

KY-65 Co-Rotating Parallel Twin Screw Extruder Machine Group (L/D=20)

Product Of Main Extruder：Food.

Capacity Range：200-250kg/H (Different According To The Formula Of Material)

Voltage: 380V– Frequency: 50Hz

Configuration of Equipment

1. Main Extruder Model KY-65 (Twin Screw Extruder)：

1.1 Main extruder is equipped with 1 set 45kw AC motor and INOVANCE frequency inverter for the speed regulation system;

1.2 1 set of Speed Reduction gearbox, with ratio of 3.74;

1.3 One Nylon Pin Coupling connection, to transfer the main power to the gearbox;

Technical Parameters

KY-65 Co-Rotating Parallel Twin Screw Extruder

1. Main Motor：

1.1 Manufactured by WanNan motor factory;

1.2 AC motor,power 45KW,rpm1500r/min;

1.3 Cooling mode; Fan cooling; Environment temperature≦40℃;Install Height≦1000m;

2. Gearbox：

2.1 New structure gearbox, high torque, high speed;

2.2 Splined sleeve to connect with the Screw;

2.3 Use imported brand bearings. Integrated thrust bearing for load sustainability

2.4 The bearing and gears are forced to adopt the immersion oil-lubrication system. No cooling oil pump;inside the gearbox has cooling coil to be connected with the running water.

2.5 Speed: 0 –400RPM.(i=3.74)

3. Feeder:

3.1 Double-screw metering feeder, double-headed structure; feeder screw diameter: ~40mm.

3.2 Motor1.1kw, with INOVANCE frequency inverter.

3.3 Stainless steel silo.

4. Screw Elements:

4.1 Combination screw elements;

4.2 Screw element involute link, single-head structure for food

4.3 Diameter of screw 62.4mm, L/D=20, quantity of barrel 5.

4.4 Ratio of screw 0-400r/min

4.5 Material W6Mo5CrV2, Hardness HRC57-58

5. Barrel：

5.1 The barrels are made by manufacturing center and the aligning pin and inner hole are completed by manufacturing center in one time. Inner hole is 6 grade which is a high precision. After assembly, the concentricity error is 0.05mm, thus greatly enhance the self-cleaning of screw and reduce energy consumption;

5.2 The barrels are equipped with stainless steel integral shielding which are secure, good-looking and power frugal;

5.3The barrels is bimetal integral alloy sleeve：HRC60-62;

5.4The barrels (except feed barrel) adopt cast-iron heaters. The barrels use soft water cooling.

5.5The first (1) barrel is feed barrel, the fifth (5) barrel is extrusion barrel and the rest barrels are closed-mouth barrel.

6.Barrel Temperature Control System：

6.1 Heating and cooling is controlled by temperature control meter through the solid state relay or electromagnetic valve, thus form a closed-loop system to control the barrel temperature. The temperature control accuracy is ±2℃ and control the flow by stop valve;

6.2 Two cooling water pipes. All the cooling pipes, joints stainless steel; Soft water circulation system including heat exchangers, 0.75kw water pump, water tank body: stainless steel.

7.Core fill mould & Rod-shaped puffed food mould.(refer to the buyer’s requirment)

Electrical Instruments Control System(PLC)

1. Control instruments adopt the following brands:

1.1 Main extruder control adopts: Siemens PLC programmable controller to realize main extruder joint control operation, display monitor of operation parameter and alarming interlock;

1.2 Electrical cabinet includes temperature control system, drive system and interlock and control system;

1.3 PLC CPU: Siemens 224XP;

1.4 PLC panel: Siemens SMART1000,10 inch screen

1.5 Temperature control module: each zone temperature of the main extruder barrel adopts double channel PID, making it possible for intelligent PID parameter auto-tune, temp. variance≤±2℃;

1.6 Main extruder speed regulator: INOVANCE;

1.7 Main control switch: LG;

1.8 Low-voltage apparatus: Schneider

1.9 Cooling solenoid valve: VMI;

1.10 AC contactor: Schneider.

2. General interlock and alarming:

2.1 Over torque protection of nylon pin;
