Why Bakers Choose the Colbake CR Conical Rounder

The Colbake CR Conical Rounder takes divided dough and turns it into tight, even dough balls, ready for proofing or the next stage of makeup. For bakeries rounding by hand, it takes over one of the most repetitive jobs on the floor.

One machine covers dough pieces from 100 g up to 2 kg, so small rolls, hamburger buns, pizza dough balls and large loaves all run through the same rounder. Choose the standard nickel-plated cone for doughs from 50 to 58% hydration, or the Teflon-coated cone for stickier doughs from 58 to 65%.

Two dials set the cone speed and the amount of flour, and the green and red buttons start and stop the machine. It arrives fully assembled, rolls on casters and works on its own or as part of a larger line.

CAPABILITY FUNCTION BENEFIT FOR PROFESSIONAL BAKERS
CONICAL ROUNDING SYSTEM A rotating cone moves each piece through 4 m of helical rounding channels Consistent rounded pieces without hand rounding at the bench
100 TO 2,000 G PIECE RANGE Rounds small rolls through large loaves on one machine One rounder covers buns, pizza dough balls and large breads
ADJUSTABLE CONE SPEED Frequency inverter and dial set the cone speed Match the speed to the dough and the load, and slow down when many pieces enter at once
INTEGRATED 10 L FLOUR DUSTER Independent motor drops adjustable flour on the exit ramp; dial at 0 turns it off Rounded pieces release cleanly, with flour only where it's needed

At a Glance
Round 100 to 2,000 g dough pieces consistently, with a nickel or Teflon cone matched to the dough’s hydration.

Typical Applications

The Colbake CR Conical Rounder sits right after the divider. Divided dough pieces are fed into the entrance, the rotating cone moves them through the helical rounding channels, and rounded pieces leave on the exit ramp, ready for proofing, moulding or the next step in the line. It runs on its own or together with other machines.

With a 100 to 2,000 g range and two cone options, it covers a broad bread program, from small buns to large loaves.

Dough Balls
Consistent round pieces for rolls, buns and any product that starts as a tight dough ball.

Large Loaves
Pieces up to 2,000 g can be rounded before resting and final shaping.

Hamburger Buns
Evenly rounded pieces help buns proof and bake to a uniform shape.

Pizza
Rounded pizza dough balls ready for proofing and storage before stretching.

Tin Bread and Franzela
Rounding before the pieces move on to final shaping for pan bread and franzela.

How Does It Work?

The Colbake CR Conical Rounder rounds dough using a rotating cone and helical rounding channels. As the cone turns, each dough piece is worked along the channel, and the movement tightens and shapes it into a round piece. The operator sets the cone speed and the flour.

1. Set the cone speed and the flour
The “Cone” dial sets how fast the cone turns, and the “Flour” dial sets how much flour the duster drops on the exit ramp. Setting the flour dial to 0 turns the duster off.

2. Start the machine
Press the green button to start. The red button stops the machine, and the emergency stop is within reach on the control column.

3. Feed the divided dough pieces
Feed the divided pieces into the entrance. The CR rounds pieces from 100 to 2,000 g.

4. The cone rounds each piece
The rotating cone carries the pieces through the 4 m of helical rounding channels, shaping each one into a rounded piece.

5. Collect the rounded pieces
Rounded pieces leave on the exit ramp, lightly dusted with flour, ready for the next step. An optional unloading conveyor can carry them away from the machine.

6. Match the speed to the load
If too many pieces enter at once, reduce the cone speed so the motor isn’t overworked. Dough consistency matters too: a dough that is too stiff won’t round as well as one with the right consistency.

7. Clean at the end of the shift
When work is finished, wipe the flour residue off with a cloth dampened with water.

Features & Technology

The Colbake CR Conical Rounder combines a conical rounding system, simple operator controls and a built-in flour duster for consistent rounding across a wide range of dough weights.

✓ Conical Rounding System
A rotating cone works with helical rounding channels 4 m long to shape each piece. The length of the channel gives every piece time to round before it reaches the exit ramp.

✓ Wide Dough Piece Range
The CR rounds pieces from 100 to 2,000 g, covering small rolls through large loaves on one machine.

✓ Adjustable Cone Speed
A frequency inverter drives the cone, and a dial on the control column sets the speed. Operators can slow the cone when the load is heavy or adjust it to suit the dough.

✓ Integrated 10 L Flour Duster
The flour duster has its own motor and dial. It drops an adjustable amount of flour on the exit ramp so rounded pieces release cleanly, and it can be switched off by setting the dial to 0.

✓ Teflon-Coated Rounding Channels
The helical rounding channels that carry each piece to the exit are coated with non-stick Teflon, so dough moves through the machine cleanly.

✓ Nickel-Plated Cone
The standard CR-N has a nickel-plated cone for doughs between 50 and 58% hydration. A Teflon-coated cone (CR-T) for wetter doughs between 58 and 65% hydration is available as an option.

✓ Simple Controls
The control column has a green start button, a red stop button, an emergency stop and the two dials for cone speed and flour.

✓ Easy to Install and Move
The machine is delivered fully assembled and rides on casters, two with brakes, plus fixing feet to hold it in place.

✓ Easy to Clean
Stainless steel covers protect the machine, and daily cleaning is a wipe-down of flour residue with a damp cloth. The belts are factory tensioned and usually don’t need adjusting for years.

✓ Quiet Operation
The noise level is under 65 dB(A).

Available Options

Three options tailor the Colbake CR Conical Rounder to the dough and the production floor without changing how it rounds.

✚ Teflon-Coated Cone (CR-T)
The CR-T replaces the standard nickel-plated cone with a Teflon-coated cone for doughs between 58 and 65% hydration. Higher-hydration doughs are stickier, and the non-stick cone helps them round and release cleanly. The rounding channels are Teflon-coated on both versions; this option changes the cone only.

✚ Unloading Conveyor
An unloading conveyor belt, 60 cm (23.6 in) long, can be added at the exit so rounded pieces are carried away from the machine instead of collecting at the ramp. It draws 0.18 kW.

✚ Stainless Steel Construction
The CR can be built with a stainless steel structure. The machine shown on this page is the stainless steel version.

At a Glance
Options for the Colbake CR include a Teflon-coated cone for 58 to 65% hydration doughs, a 60 cm unloading conveyor and stainless steel construction.

The Colbake CR rounds each divided dough piece as the rotating cone moves it through the helical channel.

On the production floor, the Colbake CR Conical Rounder turns rounding into a steady, repeatable step. In this Colbake production line, the rounder sits between dividing and the next stage of makeup, with dough pieces moving through the green helical channels and onto the exit ramp.

With the CR, the operator sets the cone speed and the flour once and keeps feeding divided pieces, and the machine delivers rounded pieces at a consistent pace. It runs on its own or with other machines, so it works as a single addition or as part of a full line.

FAQ

What is the Colbake CR Conical Rounder?

The Colbake CR is a floor-standing conical dough rounder. It uses a rotating cone and helical rounding channels to round divided dough pieces from 100 to 2,000 g at up to 2,400 pieces per hour.

How does a conical rounder work?

Divided dough pieces are fed into the entrance, and the rotating cone moves them through the helical channels. The movement tightens and shapes each piece, and the rounded pieces leave on the exit ramp.

What is the difference between the CR-N and the CR-T?

The CR-N is the standard model with a nickel-plated cone for doughs between 50 and 58% hydration. The CR-T has a Teflon-coated cone for stickier doughs between 58 and 65% hydration. Both have Teflon-coated rounding channels; only the cone changes.

What dough weights can the CR round?

The CR rounds dough pieces from 100 to 2,000 g (3.5 to 70.5 oz). Production is up to 2,400 pieces per hour, or 1,200 pieces per hour for large pieces.

What products can I make with the Colbake CR?

Typical products include dough balls, large loaves, hamburger buns, pizza, tin bread and franzela. Rounding quality depends on the dough, and a dough that is too stiff won’t round as well as one with the right consistency.

Does the Colbake CR divide dough?

No. The CR rounds dough pieces that have already been divided. It is usually placed after a divider, either on its own or as part of a line.

Can I adjust the speed and the flour?

Yes. One dial sets the cone speed through a frequency inverter, and a second dial sets how much flour the 10 L duster drops on the exit ramp. Setting the flour dial to 0 turns the duster off.

What options are available?

Options include the Teflon-coated cone (CR-T), a 60 cm unloading conveyor and a stainless steel structure.

What power does the Colbake CR need?

The CR is rated at 1.0 kW and runs on 220 V, single-phase, 60 Hz power. Have a licensed electrician confirm your supply and make the connection, and contact Erika to confirm the electrical configuration for your order.

What support does Erika provide with the Colbake CR?

Erika covers the Colbake CR with a warranty of 1 year on parts and 90 days on labor, and we keep Colbake spare parts in stock in the US. Training is available at installation, at our Baker’s Lab in West Caldwell, NJ, or by video, and installation and startup can be arranged as part of your consultation. You can also test your dough on the CR at the Baker’s Lab before you decide. For parts, troubleshooting or repair requests, visit our Parts, Service & Technical Support page.

How do I clean and maintain the CR?

At the end of the shift, wipe flour residue off with a cloth dampened with water. The belts are tensioned at the factory and usually don’t need adjusting for years; if pieces stop advancing, consult the manual or an Erika service technician before adjusting anything.
