WORKING PRINCIPLE

The complete set of electric components are fitted in the control cabinet located at the end of the cooling tunnel. A microprocessor made by the Omron Co., Japan is introduced to set and regulate transportation speed and temperature and to start and stop ventilators as well as electric heating device. A main operation panel is fitted at the infeed side and an auxiliary panel is located at the rear side of the tunnel. It is possible to check, set and adjust through the main panel the belt speed, and to start/stop ventilators and electric heating device and to turn off the tunnel. An emergency stop button is fitted on the auxiliary panel.

MAIN CONSTRUCTION

A. Transportation

Nine conveyor belts of 6000mmX350mm are driven by a 2.2 kw motor with a double-stage chain system to take over the continuously extruded ropes. Special transferring device is located at the entrance and the exit to deliver the extruded ropes to the wrappers. Running speed of the conveyor belts is infinitely adjustable within the range of 0-0.5m/s (maximum 30m/minute) and is controlled by a Japanese frequency converter.

B. Support

Strong supports are provided along the tunnel. Insulation walls around the tunnel is surrounded by slabs of rolled sheet steel filled with foamed insulating stuffing. Two glass doors stands in the front and at the rear side for the supervision of interior running status. There are six doors altogether for checking and maintenance the tunnel.

C. Air Circulation

The air condenser in the tunnel is cooled by an exterior refrigeration unit. Two axle ventilators propel the cool air in the tunnel to circulate to reach the set temperature. Three adjustable electrical units for heating and dehydration are also installed to help the tunnel operation under constant humidity and temperature in accordance with technical requirement for specific product.

D. Electric Control

The complete set of electric components are fitted in the control cabinet located at the end of the cooling tunnel. A microprocessor made by the Omron Co., Japan is introduced to set and regulate transportation speed and temperature and to start and stop ventilators as well as electric heating device. A main operation panel is fitted at the infeed side and an auxiliary panel is located at the rear side of the tunnel. It is possible to check, set and adjust through the main panel the belt speed, and to start/stop ventilators and electric heating device and to turn off the tunnel. An emergency stop button is fitted on the auxiliary panel.

E. Refrigeration

A complete refrigeration system working with refrigerant R22 is composed of imported compressor, a refrigerating unit, a condencer and is characterized by appropriate working pressure. The system offers smooth running of the belt, low noise and excellent cooling effect. Four refrigerating units are de-frosted in intervals and can work continuously under low temperature.

We are engaged in offering a comprehensive range of Ball Gum Extruder that is manufactured using quality proven raw material sourced from reliable vendors. These extruders are thoroughly tested for quality and are available in various technical specifications. Available with various machines, these can also be customized as per the clients’ requirements.

 

Following are the machines that we are offering:

 

• Heavy duty sigma mixer

• Stainless steel twin rope extruder

• Automatic multi way cooling tunnel

• Automatic cut & wrap machine

• Chewing gum cutting machine

• Automatic pillow pack machine

• Revolving stainless steel coating pan

MECHANICAL CONSTRUCTION

The extruder is equipped with 2 individual heating units. Heating or cooling of extrusion barrel and head is controlled respectively by 2 water tanks via thermoregulators with digital display. The set temperature and the actual temperature are shown on the display. Automatic adjustment starts when temperature has been set.

A sliding clutch connects the infeed rollers with the gearbox. Release of the clutch disconnects the infeed rollers from the gearbox, enabling the top extrusion chamber and the infeed rollers to be opened through a hinge for cleaning.

The gearboxes are also installed on the extruder. Each unit includes gears gone through thermal process. All axles are fixed on ball bearings. The gears and the bearings run in an oil bath. The hydraulic reservoir is filled with special oil resistant to high-pressure. The level of the oil can be observed by level glass. An electronic over-pressure protection device is fitted in each barrel accurately controlled by a microprocessor.

ELECTRIC APPLIANCES

One A.C. frequency converter together with main driving motor is introduced to infinitely adjust the extrusion speed.

Each set of extrusion screws is assigned with a variator to regulate the ratio depending on various raw materials to be extruded. “Speed Up” or “Slow Down” Operation is achieved by a variator when the ratio has been fixed.

The extruder is equipped with 2 thermo-regulator with temperature display. All electric components and adjustment device are positioned at eye's level. All contactors, relays and fuses are installed in the control cabinet.

We offer Heavy duty sigma mixer which are know for giving maximum output with minimum wastage.

The main structures:

• The trough and the mixing blades are made of  stainless steel which are easy to clean and offers a long service life.
• The mixing blades of the mixer are of ¡°z¡± shape, which can be used not only for mixing and kneading, but also for stirring, blending, beating, homogenizing and plastifying of the ingredients. The clearance between the wall and blades is very small to avoid the retain of the gummass.
• Take the advantage of the opposite rotation and inch-stop performance of the mixing blades, as well as the tilting function of the trough by means of the worm gear and screw driving system, makes the discharge of the ingredients very easy, safe, reliable and sanitary.
• Double-jacket of the trough is provided for heating up the gummass, and can be connected to its own heating system for warm water circulation.
• The electric components and control system are of reliable and safe design with interconnection of various functions according the International standard.
