Apparatus and method for preserving mucosa

A method for preserving slaughter offal comprising the following steps:

• a) providing an empty preservative reservoir and an empty collection tank, each with a minimum height level sensor placed at a minimum height and a maximum height level sensor placed at a maximum height,
• b) filling the preservative reservoir with a preservative agent from an automatic supply of preservative agent,
• c) using a programmable control unit to stop the automatic supply of preservative agent adding preservative agent after the maximum height level sensor in the preservative reservoir detects that a maximum height level is reached,
• d) adding the preservative agent in the preservative reservoir to the collection tank until the minimum height level sensor in the preservative reservoir indicates the minimum height level is reached,
• e) filling the collection tank (3) with mucosa from an automatic supply of mucosa,
• f) using the programmable control unit to stop the automatic supply of mucosa adding the mucosa after the maximum height level sensor in the collection tank detects that a maximum height level is reached, wherein the mucosa and the preservative agent are mixed to form a preserved mucosa compound,
• g) opening a closable discharge and activating a pump unit and discharging the preserved mucosa compound in the collection tank to a container or storage tank, and
• h) closing off the discharge and deactivating the pump unit when the preserved mucosa compound in the collection tank reaches a minimum level detected by the minimum height level sensor.
