• c) filling the preservative reservoir (7) until the maximum level in the preservative reservoir is reached,
• d) stopping the supply of preservative agent,
• e) adding the total amount of preservative agent to the collection tank (3),
• f) detecting the absence of preservative agent by the minimum level sensor in the preservative reservoir (7),
• g) starting the supply of mucosa,
• h) filling the collection tank (3) with mucosa until the maximum level in the collection tank (3) is reached,
• i) opening the discharge and activating the pump unit (9) and discharging preserved mucosa compound to a container or storage tank,
