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.

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.


STV 41

Fully automatic machine for forming product stacks especially for flat round products like Lebanese bread. The standard version can be extended to meet special requirements depending on the output requirements and product format. The large individual products are continuously fed in the direction of travel and stacked in a controlled manner. The product stacks are forwarded one after the other in a controlled manner to the following processing devices.

The clear and easily accessible design allows easy adjustment, cleaning and inspection.
