Diosna Spare Parts for Bakeries

Diosna is one of the best-known manufacturers of mixing machines in bakery technology. The machines are known for their robust construction and high operating hours – and are correspondingly widespread in artisanal and industrial bakeries. Here you will find suitable spare parts for Diosna spiral mixers and vertical mixers.

About Diosna

Diosna Dierks & Söhne GmbH was founded in 1885 in Osnabrück and is one of the oldest manufacturers of machinery for the food industry. For decades, the focus has been on the development and production of mixing machines for bakeries. Diosna machines are known for their longevity. Many models are still in use even after 20 or 30 years of operation.

For which Diosna machines do we offer spare parts?

Diosna spiral mixers

Diosna spiral mixers are among the most widely used mixing machines in German bakeries. They operate with a rotating spiral that develops the dough gently and evenly. Typical wear parts are mixing spirals, bearings, drive belts, and seals.

Diosna vertical mixers

Diosna vertical mixers are primarily used for heavy and stiff doughs. The mixing arm is moved vertically, which enables intensive dough processing. Frequently required spare parts are mixing arms, bearings, gearbox parts, and control elements.

Which spare parts are needed most frequently for Diosna machines?

Across both machine types, the following components wear out most frequently:

• Mixing spirals and mixing arms
• Ball bearings
• Drive belts
• Gearbox parts
• Switches and control elements
• Seals and shaft seals

Timely replacement prevents consequential damage and unplanned production downtime.
