Frequently asked questions

Can different slicer band blades be used?

In a tape cutter slicer band blades of the same manufacturer with the same pitch and shape are always used. Complete sets are always interchangeable. If very different types of bread are cut, different sets of knives make sense.

How is the blade change performed on a belt cutter?

The slicer band blades are a wearing part of the band cutter. The service life of the slicer band blades varies depending on the type of bread. Usually a complete set of slicer band blades is always changed, as the slicer band blades stretch slightly during use and thus become "longer".

For the slicer band blades change you can disassemble the knife guide for easy accessibility quickly and easily. Depending on the experience, changing a knife set takes about 5-10 minutes

How loud is a machine by GHD Hartmann?

The noise emission initially depends on the type of machine. Packaging machines, cutters or systems for grouping are fundamentally different due to the different functions.

Another factor is the nature of the products, which can behave differently during processing and transportation. A machine may be very quiet at idle, but produces varying amounts of noise during processing, depending on the products.

The type of cover also has a great influence on the noise emission: Polycarbonate viewing covers significantly reduce the noise level, while perforated grids can not significantly reduce noise emissions.

As a rule, the maximum noise emission of the machines is not more than 78 dB (A).

Which controls can GHD Hartmann Maschinenbau offer?

In addition to contactor controls for simple devices, GHD Hartmann Maschinenbau offers systems from the manufacturer Omron as a standard controller for more complex tasks.

Siemens or Allen Bradley are available as options.

What compressed air quality is recommended for machine use in the food industry?

According to ISO 8573-1 with reference to VDMA standard sheet 15390-2, we specify a compressed air quality that we recommend when using the machines and devices.

What is the difference between a fixed blade guide and an adjustable blade guide?

Adjustable blade guides:

 

Negative:

  • Complicated access for cleaning
  • Complicated exchange of guiding pads
  • One position for wearing of pads
  • Correct cleaning would require the dismantling of the both adjustable guides. This requires hours
  • Not according to sanitary demands (local laws and rules)
  • If used in combination with oil the unit might “stick together”

Positive:

  • One system for every slice thickness (if within the adjustable range)
  • Tolerances within the length of loaves are divided to the slice thicknesses

 

Exchangeable blade guides

 

Negative:

  • One set of blade guides per slice thickness required

Positive:

  • Always correct adjustment of slice thickness
  • Fingers could be turned several times in case of wearing
  • Fingers could be easily exchanged in case of wearing
  • Jet-wash cleaning and drying outside the packaging area
  • Good access for cleaning
  • Good access for blade exchange
  • Better visibility of the slicing process

What should be considered when using a density scanner?

When using X-ray inspection systems, user-specific laws and regulations must be observed by the user. To operate the plant within the EU, the operator of the facility must be trained as a radiation protection officer. The radiation protection approval (TÜV approval) should take place during commissioning.

A radiation protection inspection can only be commissioned by the operator of the facility. A decrease can be accompanied by WIPOTEC-OCS GmbH or GHD Hartmann.

Can the machine be cleaned wet?

The machines are designed according to protection class IP54. Wet cleaning of the machines inside the cutting and packaging room is not recommended as moisture and bread crumbs directly cause the formation of mold spores.

Wet cleaning should therefore only take place outside the cutting and packaging room: components of the machine, such as guide plates, can be dismantled and cleaned at an external washing area. After drying and disinfection, the hygienically flawless dry components can be inserted into the device and reused.

Change kits allow cleaning and preparation in addition to the production operation.

Is it possible to combine a GHD Hartmann Schneider with other packaging machines?

Of course, our bread slicers can not only be combined with capping and packaging machines from GHD Hartmann, but also with machines from other manufacturers.

Take advantage of our many years of experience for optimum coordination and connection.
