Cabinet and tool equipment Hygiene and disinfection The cabinet of the unmanned vending machine is the place for food cold processing and long-term storage of food. The sanitation management of the cabinet is the central link of the whole unmanned vending machine hygiene management. In the cabinet, molds multiply faster than bacteria and are highly susceptible to food. Therefore, the cabinet should be disinfected irregularly. Stows, trolleys and other equipment should be washed and disinfected regularly outside the cabinet. It can be rinsed with hot water first, and the oil is removed with 2% alkali water (50 ° C), and then disinfected with a bleach solution containing 0.3%-0.4% of available chlorine. All equipment used for processing, such as weighing pans, hooks, work tables, etc., should be rinsed with clean water before and after use, and if necessary, hot alkaline water disinfection. The walkways and stairs in the unmanned vending machine should be cleaned frequently. Especially when entering and leaving the cabinet, the residue such as minced meat on the floor should be cleaned in time to avoid polluting the environment.
