A clean grinding solution

06 June 2021

The cleaning chambers in K+G Wetter grinders and mixer grinders are designed to ensure double hygienic safety when grinding. 

During the grinding process, product is conveyed through the cutting set at high pressures. Fluid product components, such as blood, meat juice and liquids, or even small product particles, can be forced backwards against the cutting set by the resulting pressure.

The high pressure and microscopic imperfections in the components allow microorganisms to bypass the seals which enables organisms to proliferate in the relatively undisturbed conditions encountered there. Where the bacterial population is sufficient, the material undergoing processing can become contaminated. 

Cleaning seals from both sides is good practice for avoiding this effect. However, cleaning the reverse side of the seals cannot normally be carried out on the worm drive of a meat grinder because the inside of the machine is not easily accessible to the cleaning personnel.

The hygienic design of the K+G wetter cleaning chamber, however, allows users to rinse the back of the seal from the outside using a cleaning agent and water jet. This means that both sides of the seal are cleaned. Another seal is installed towards the drive to protect it from water. The cleaning water is directed out of the cleaning chamber onto the floor via a drainpipe, so that water is unable to remain inside the cleaning chamber. Even with older seals that have received insufficient maintenance or that exhibit wear, the cleaning chamber ensures proper cleaning of this critical area and the effective removal of deposits.
