1. OVERVIEW AND OPERATION

1.1 DESIGNATION

The RoboJetFloss machine is intended to produce cotton candy using sugar with or without added flossine. Due to the patented design, this model allows operation under high ambient temperature and relative humidity. Candy floss leaves the machine vertically, producing servings up to 2 meters (6 feet) in diameter. With practice, you can move up to 5 meters (16 feet) away from the machine and continue to make candy as the stream will follow you in a continuous trail!

This is a very popular model of cotton candy. Some operators believe that today it is the best commercial cotton candy machine. Find out more here

1.3 MACHINE DESIGN AND OPERATION PRINCIPLE

The RoboJetFloss includes the following main components: Housing (1); Chassis (2) with electric motor and Spinning Head (3). The spinning head and electric motor are mounted on the chassis, which itself is connected to the housing by four spring-mounted supports. These spring supports dampen vibrations and allow the motor to self-balance during operation.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

Plastic/Aluminum floss pans (18) are not shown.

An electric motor drives the spinning head at a high rate of speed (see datasheet). A Stator (4) is mounted on the chassis to direct airflow in an upward spiral. It is fitted with a silicone Sealing Collar (5) which seals the gap between the floss pan and the stator to prevent sugar from falling onto the chassis. An adjustable Silicone Ring (6) covers the intake grill to regulate air flow.

The Spinning Head has the following main parts: Impeller (7); Base-plate (8); Sidewall with the heating element (9) and Cover (10).

OPERATING PRINCIPLE

The spinning head rotates with the sugar mix inside where the heating element warms the sugar up to its flow point 120-140°C (250-285°F). Due to centrifugal force, the melted sugar escapes through laser cut slits in the sidewall, where it instantly cools and crystallizes turning into candy floss.

An attached impeller rotates along with the spinning head, producing a powerful upward airflow. Air enters from below, through the axial grills of the stator, which can be restricted by the silicone collar.

The airflow can lift the cotton candy several feet in the air. Sugar particles that are too heavy will collect in the floss pan (not shown).

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

The front panel has the following controls: Switch (11) turns on the electric motor which rotates the spinning head; Switch (12) turns on the heating element; Adjustment Knob (13) regulates power to the heating element and thus controls its temperature; Voltmeter (14) indicates actual voltage supplied to the heating element.

The ‘PRO’ version includes a ‘Quick Start’ button (15) which temporarily sends maximum power to the heating element, even when the electric motor is not running.

See the figure above for the machine front panel. Appearance may vary depending on your specific model.

2. INTENDED USE

2.1 PROTECTORS AND LOCKUPS

Four nuts secure the spring-loaded chassis during transportation to prevent damage to the motor. They are located on the threaded support studs at each corner of the deck.

Rubber legs and a spring suspension support the chassis to minimize vibration and allow the spinning floss head to balance itself at high speed.

The stator prevents operators and objects from coming into contact with the rapidly rotating impeller.

2.2 PREMISES REQUIREMENTS

The equipment may be operated in temperatures ranging from +5°C to 40°C (+41°F to +104°F) with relative humidity not exceeding 50% at 104°F.

As temperature and humidity increase above these ranges, cotton candy can still be produced, but it will be very dense and heavy. Importantly, being a sugar product, it may begin to melt shortly after being produced.

Altitude above sea level should not exceed 1000 m (3280 ft).

2.3 RAW MATERIAL REQUIREMENTS

Use only 100% pure sugar (beet or cane) with flossine or ready to use flossugar. Do not use sugars with starch, dextrose or similar additives as they can result in poor quality floss and/or clog the heater coil assembly.

2.4 GETTING STARTED

Unpack machine and save materials for future shipping needs.

Place the machine on a stable table or cart.

Before attaching the power cord, fully raise all four transportation fastening nuts (16) until they reach the rubber floss pan supports.

Wash silicone ring and silicone collar with dish soap. Carefully install the silicone ring on the stator. Adjust the exposed gap on the stator intake to regulate airflow depending on ambient conditions.

For indoor operation 20° C (70° F) and 50% RH minimize airflow by exposing no more than 0.5-1.5 cm (<½ inch) of the intake grill:

Next, remove the thin protective film from the Floss Pan and wash with dish soap. Place the pan on the machine making sure the indentations rest on the four rubber support legs.

RoboJetFloss instruction operating manual

Floss pan indentations (shown above) should fit rubber support legs (17). Carefully install silicone collar (5) on the stator with the collar edge overlapping the pan.

2.5 OPERATION

Before turning on the machine, first add 350 g (1½ cup) flossugar to the spinning head, or approximately ¾ full. The minimum recommendation is 1/3 full at all times. Manually rotate the head to distribute the sugar evenly.

You will need sticks, rods or cones to spin above the machine to collect the cotton floss as it is produced. These can be made of wood, paper or plastic. The longer the sticks, the larger the servings of cotton you can create. For the RoboJetFloss the ideal length is 50-60 cm (1 ½ ft – 2 ft).

Wood sticks and plastic straws should be soaked in water first to create better adhesion for the floss.

Turn main power switch (11) ON, and the spinning head will begin to rotate.

 RoboJetFloss candy floss machine instructionVIBRATION OF THE SPRING MOUNTED CHASSIS DURING FLOSS HEAD ACCELERATION AND DECELERATION IS NORMAL.

Next, turn on the heater coil power switch (12), and use the adjustment knob (13) to set voltmeter(14) to between 150-160 V (EU version) or 70-80 V (US version).

Depending on conditions, it will take about 1 minute to warm up the head to operating temperature. You will usually smell the candy aroma between 10 to 15 seconds before production begins.

Cotton floss will fly out upwards in a vertical column or “sleeve.” This sleeve can be wrapped around a stick by rapidly turning or spinning the stick with your fingers in a counter-clockwise direction (see below).

You will usually want to collect floss between 20-40 cm (8” to 14”) above the spinning head, though you can adjust for conditions and the size of the serving.

If you find airflow is too strong or weak, turn off the machine and adjust silicone band on the stator (see Airflow adjustment section below).

‘COLD START’ PROCEDURE

When the machine has been off for more than 15 minutes, it will take at least 60 seconds before the heating coil has warmed enough for the production of floss to begin. If the machine has been off for a brief time, such as to add more flossugar, this time will be reduced substantially.

Users of the ‘Pro’ version can press and hold the ‘Quickstart’ button (15) for 10 – 15 seconds. This will send full power to the heating element and can be done even if the main power switch is off. This will also substantially reduce the time required to begin candy production.

Owners of the standard version can achieve a similar result by manually adjusting the voltage regulator. After switching on both the motor (11) and heating element (12), an experienced operator can adjust the voltage regulator to the maximum (13). But, again for only 10 – 15 seconds, and then decreasing the voltage back to the recommended operating range between 70-80 V and proceeding as normal from there.

However, in neither case above should maximum voltage be applied for more than 10 -15 seconds as you risk overheating the flossugar. If this occurs, the cotton candy would then be produced in a narrow rope that is difficult to capture. In an extreme scenario, the floss would be burnt and ejected as irregular flakes and sugar dust that would create a mess covering everything in the immediate area.

The figure below shows an example of a mildly overheated heating element.  Notice the cotton candy is rising more like a ‘rope’ than a wide “sleeve.”

RoboJetFloss instruction operating manual

Keep in mind that once the heating element and sidewall have reached such a high temperature, reducing the voltage will not immediately produce the desired effect.  Due to thermal lag, any changes in voltage will only slowly take effect over the next 15 to 30 seconds (or longer, depending on ambient temperatures) so it is very important to avoid overheating the element in the first place.

‘NO-SNOW’ TOOL

In the production of cotton candy, “snow” includes flakes, flecks, small filaments, and sugar dust that are all too small to be collected in the normal winding process of producing a cotton candy serving.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

There are four situations when “snow” will be emitted from the head:

  1. At the very beginning of the operation.
  2. During the end of production.
  3. When there is not enough flossugar remaining.
  4. If the coil and sidewall are overheated.

In both the beginning and ending of operation, snow is produced as the heating element crosses the temperature threshold at which it can evenly and uniformly melt the flossugar in the head into quality candy floss.

The same is true when there is not enough flossugar left in the head because the remaining sugar will not be evenly distributed and this will cause some of the material to overheat. Keeping the floss head at least 1/3 full at all times will prevent this from occurring.

Finally, if the coil and sidewall become extremely overheated, then brunt sugar flecks and dust will be produced instead. Paying attention to Voltage regulation and not excessively preheating the coil during cold startup will ensure this does not happen.

Regardless of the cause, you can prevent the distribution of snow (which can create a mess) by placing the ‘No-Snow’ tool (26) over the spinning head, where it will capture the snow as it is ejected.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

However, you should not leave the ‘No-Snow’ tool in place for long periods as it will eventually become filled with floss which will then collect on the spinning head itself.

To help prevent this, the inside of the “No Snow” tool should be wiped off in between each use to prevent excess accumulation of spent flossugar.

If you do notice melted or burnt sugar accumulating on top or lip of the spinning head cover, or excessive buildup on the sidewall, then this should be scraped off before proceeding.

This can be done using a wooden bamboo skewer or stick (never metal) while the head is spinning. Gently put the tip of a stick into the inner right-side edge of the cover and allow the rotation of the head against the stick to scrape off any sugar accumulation. This can be repeated on the outside of the sidewall as well, again only on the right side of the spinning head.

Scraping should not be done when customers are nearby as small pieces of sugar could fly some distance posing a risk to the face and eyes.

AIR FLOW ADJUSTMENT

When operating indoors, airflow should be kept to a minimum. The silicone band should cover the stator intake grill almost completely, exposing only 7 – 13 mm (1/3” – 1/2”) at the base per the figure below.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

As you expose more of the intake grill, the intensity of the airflow will increase. This is useful for performing tricks and also for outdoor operation where humidity will make for denser and heavier cotton candy and to overcome any wind that may also be present.

However, with increased airflow, it becomes more difficult to take control of the sleeve of candy being produced. There is no “correct” setting as it will depend entirely on how you wish to operate the machine and control the production.  During setup, some experimentation will be required as condition vary. Removing the sleeve entirely is common when working outdoors in warm and humid weather, as pictured below.

VERTICAL FLOW MACHINE OPERATION RECOMMENDATION

RoboJet Floss is intended for prolonged operation at a high production rate.

Only vertical flow machines allow you to perform entertaining tricks when making cotton candy. The most common technique is forcing the candy sleeve to follow you several feet away from the machine like a “snake” or animated rope.

The “snake” trick requires plenty of space, and note that if there is wind present you will have to have the floss follow you down-wind.

Once you have made a small cloud on the stick, pull it smoothly away from the machine (see the figure below). Keep winding the cotton candy, and do not let it fall below the floss pan. Be careful, as winding too rapidly might break the sleeve.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

By moving move your hands up and down and changing the angle of the stick, you will find that you can modify the shape of the snake.

Once you have the hang of it, you will be able to step away from the machine, as far as 3 to 5 m (10′ to 15′, depending on conditions) and the snake will follow you if you continue the proper winding rate.

SHUTTING DOWN

When shutting down for periods of less than 24 hours, you may leave any remaining flossugar in the spinning head.

Turn off power to the heating element switch (12) and capture the remaining cotton candy as the head cools down.  When the coil cools to the point that “snow” is produced, then cover the head with the “No Snow” tool and allow the head spin for 5-7 minutes to fully cool down before turning off the main power switch (11).

Once cool to the touch, wipe out the inside of the “No Snow” tool, and put it back over the spinning head for protection. You can also cover this with a paper or plastic bag to protect the flossugar from dust, debris, and insects.

The machine and Floss Pan should be wiped down with a damp cloth to remove excess flossugar as needed.

If you are shutting down for longer than one day, then you should perform a complete cleaning of the spinning head as described in the Technical Maintenance section below.

Do not leave unused flossugar in the spinning head for more than a day or two as it can harden/caramelize and affect the balance of the head during future sessions, which could ultimately fail the machine.

During transportation always secure the chassis using the transportation lock-down nuts. This will prevent possible damage to the machine and prolong its life.


3. TECHNICAL MAINTENANCE (RoboJetFloss instruction operating manual

3.1 GENERAL INSTRUCTIONS
 RoboJetFloss candy floss machine instructionATTENTION! THIS PART OF OPERATION MANUAL IS INTENDED ONLY FOR TRAINED PERSONNEL EXPERIENCED WITH ELECTRICAL EQUIPMENT.
 RoboJetFloss candy floss machine instructionDO NOT CLEAN THE SPINNING HEAD OR COMPONENTS WITH SHARP OR METAL PARTS. HOT WATER, A SPONGE OR SOFT BRISTLE BRUSH IS ALL THAT IS REQUIRED OR PERMITTED!
 RoboJetFloss candy floss machine instructionDISCONNECT THE POWER SUPPLY BEFORE CLEANING OR PERFORMING TECHNICAL MAINTENANCE!

The purpose of technical maintenance is extending the working life of the machine while fulfilling all safety requirements.

The following schedule is recommended:

 

PROCEDUREPERIOD
Cleaning machine and pan surfaces removing sugar and cotton candyOnce a day
Sidewall and heater cleaningTwice a month
Brush unit maintenanceEvery six months

SPINNING HEAD CLEANING

During long-term operation, the heating element and sidewall slits can become clogged with sugar and carbon deposits. This may significantly reduce both productivity and the quality of the cotton candy produced.

To clean the sidewall and heating element, it is necessary to disassemble the spinning head, remove the heating element and sidewall and wash them carefully with hot water.

RoboJetFloss instruction operating manual
RoboJetFloss instruction operating manual

To disassemble the spinning head:

  1. Remove all sugar from the head, turning upside-down if necessary.
  2. Detach floss head cover (10) by removing three flat-head screws (23).
  3. If the cover is ‘glued’ to the sidewall, gently tap with the screwdriver handle to loosen the parts.

Note that the cover is made from aluminum and can be damaged by excessive tightening the screws, by throwing, or by a heavy impact.

  1. Remove central wing nut (21), steel washer (20), plastic holding washer (19). Then, using a 7mm nut driver or wrench, remove the nuts that are securing the wire ends to the terminal posts (26). Remove the nuts, lock washers, terminal ends and washers and you can then lift off the sidewall with a heating element (9) as one unit.
  2. Wash the sidewall and heating element with very hot water to melt the flossugar. When the bulk of the flossugar is removed, carefully separate the heater coil from the sidewall to clean the areas where they contact one another.
 RoboJetFloss candy floss machine instructionDO NOT IMMERSE HEATING ELEMENT TERMINAL LEADS IN WATER AS THIS MAY CAUSE FAILURE!
  1. The sidewall and heating element must be dry before reinstalling.

 

 RoboJetFloss candy floss machine instructionABRASIVE OR MECHANICAL CLEANING OF HEATING ELEMENT AND SIDEWALL IS PROHIBITED!

Re-assembly of the spinning head is done in the reverse order. Once completed, turn on the motor and power to the heating coil for approximately 30 seconds to spin off any remaining moisture.

BRUSH UNIT MAINTENANCE

As with most electrical motors, the Robo JetFloss utilizes brushes and slip rings which are subject to wear and require inspection, maintenance, and eventual replacement.

To inspect and maintain the brush unit it is necessary to take off the stator (4) by removing the four fastening screws. Next, remove the impeller (7) by removing three fastening screws.

Inspect the slip rings (24) for bumps and color changes. The rings should fit closely to insulators and should not show excessive wear.

Slip rings are made of high-grade brass and will last years if properly serviced.

If the slip rings are excessively worn or are covered with bumps, they need to be replaced by qualified service staff.

RoboJetFloss instruction operating manual

To replace brush units (25) first remove the screws securing the brush unit. Remove the unit carefully and inspect the carbon brushes. If the brushes are worn more than half of the length, they should be replaced.

 RoboJetFloss candy floss machine instructionAFTER BRUSH UNITS ARE REPLACED, REMOVE ALL DUST, DEBRIS AND TARNISH FROM THE SLIP RINGS (24).

After installing new brushes, allow the motor to run for 15 minutes before turning on the heating element. This will allow the brushes to conform to the slip rings, avoiding the potential for arcing under load.

3.2 STORAGE

If the unit is not used for a prolonged period, then the routine maintenance must be performed before it is placed back into service.
