Gum
Gum Manufacturing
Gum processing includes a wide range of a gum products, many of which require a unique process or machine. Executive Srl’s gum processing equipment covers all types of gum production and their team of technical experts work closely with our customers to ensure a successful, custom solution for every application.
Pre-Extrusion
Pre-extruders receive dough (mass) from mixers and use a temperature-controlled chamber and die-head to feed a continuous sheet of gum mass for downstream processes. Pre-extrusion ensures that the gum being fed is homogenously distributed and at the proper temperature.

Capacity
From 300 to 2,000 Kg/h
Features
Pre-Extruder is available in different production sizes from 300 up to more than 2,000 Kg/h capacity.
PLC control for all parameters
Direct drive technology with independent motorization for screws and side paddles
Optional heated infeed hopper
Optional automatic hopper loading from bins
Benefits
User-friendly die-head change-over and reconfiguration or adjustment depending on application
Safe, easy cleaning and maintenance
Spacious hopper for high batch capacity feeding
Stabilization
The gum must crystalize before extrusion.
Stabilizing Belt
A stabilizing belt is installed between a pre-extruder and extruder. During this step, the mass travels on a temperature-controlled belt that is also speed adjustable. Once gum has enough time to crystalize, the mass transitions to the extruder and continues on to the forming process.
Capacity
Up to 1,000 kg/hr
Features
Adjustable speed/residence time
Adjustable temperatures
Built-in tempering unit
PLC with process parameters control
Options to handle dual colors simultaneously
Benefits
Easy Cleaning
Low Maintenance
Safe to operate
Extrusion
Once the mass is ready, it will be extruded into ropes or a flat sheet. Ideally, a pre-extruder is used to feed the main extruder in norder to ensure a constant flow of product to the main extruder. Irregularities in the flow of product feeding may cause issues further down production. Co-extruders may also be used to combine two different masses (color and/or flavor) into a single rope.
Extruder and Co-Extruder
Extruders ensure that the mass received from upstream equipment is fed continuously and consistently as a rope to the downstream forming line. This is achieved via a temperature controlled chamber and die-head. Co-Extrusion makes it possible to combine two masses (for example – gum and chewy candy) or two colors/flavors. This allows for great flexibility to make different products by simply changing the die-head. All extruders can be offered with pumps for liquid or powder filling.
Features
Hydraulic system opens extruder completely, exposing chamber and die-head for cleaning and maintenance
Accurate and independent temperature control of both chamber and die-head
PLC control for all parameters
Options for liquid or powder filling.
Easy die-head change-over and reconfiguration
Benefits
Safe Cleaning
Easy Maintenance
Rope Sizing
Often times, the extruded rope must be reduced to a thinner diameter. The rope sizer reduces the diameter of rope to an appropriate size for forming.
Rope Sizer
The rope sizer receives a thick rope of gum from the extruder and reduces it to a size suitable for forming . It does so by passing the rope smoothly through a series of adjustable calipers that provide controlled sizing.
Capacity
Up to 180 m/min
Features
2 to 8 stages with mechanical or servo-driven adjustment
Automatic rope control and synchronization
Anti-stick calibrators
Safety protection built into each calibrator
Cooling System for gum handling
Lubrication system for sticky product handling
Benefits
Easy to clean
Low maintenance
Easy rope feeding
Quick and easy adjustment
Relaxation
A relaxation belt allows time to stabilize the gum and prevent deformation.
Relaxation Belt
Rope is fed to a controllable belt with a programmable pattern, giving time to release internal tensions.
Features
Automatic rope control and speed synchronization
Can use either ambient or conditioned air to stabilize product.
Adjustable residence time
Parameters and operations controlled by PLC
Benefits
Avoids rope accumulation and stretching
Allows adequate time to release internal tensions
Rotary Forming
Rotary forming continuously cuts the gum from the upstream rope sizer to a target shape and weight.

During rotary forming, the machine receives rope from the upstream rope sizer and cuts it by compressing each piece inside a specially-designed forming chamber. This creates individual pieces of gum with a target shape and weight. Rotary forming is the most flexible option and provides the least amount of ‘scrap’.
Capacity
| Rotary Forming Type | Output (kg / hr) | Rope Speed (m / min) |
|---|---|---|
| MOD. 256 - EXEC - MINIFLEX | Up to 300 | 30 |
| MOD. 114 - EXEC | Up to 700 | 110 |
| MOD. 195 - EXEC | Up to 1200 | 130 |
| MOD. 239 - EXEC - FLEXI | Up to 1600 | 160 |
Features
Infeed sizing rollers for rope final adjustment
Long-lasting hardened forming cams and rollers
Accurate forming pressure adjustment.
Product thickness adjustment
Patented free-pressure rollers for extended forming dwell time and avoiding plungers overheating.
Upgrades capable of achieving Pharma Standards
Benefits
Flexible solution to achieve seamless, small shapes
Less 'scrap' than chain-forming
Easy to open
Cooling
Cooling tunnels are used after the forming process to drop the mass/product temperature and stabilize its shape.
Cooling Tunnels
Executive can provide a variety of cooling solutions depending on the application. All are equipped with either connection to chillers or direct expansion. Tunnels are all designed for sanitary, food grade processes, and all have been designed for best shape retention to avoid product deformation.
