Dishwashing Procedures CS 1(SS) FOSTER

Learning Objectives o o Discuss the two different types of ware washing Explain the steps for both types Review temperature ranges for each step Discuss safety concerns

Types of Dish-washing o Ø Ø o The Navy employs 2 types of dishwashing: Manual: using the classic 3 -bay sink model (if available) and washing dishes by hand. Mechanical: using a dishwashing machine that automatically cycles through each step. There are some different considerations for each type, based mainly on user contact.

Manual Dishwashing 3 -bay Sink – WASH – RINSE - SANITIZE

Manual Dishwashing Steps o There are 6 steps: 1) Sorting Scraping Washing [110 - 120°F] Rinse [120 - 140°F] Sanitize/Final Rinse [171°F+ or chemically] Air Dry 2) 3) 4) 5) 6)

Manual Dishwashing o o o The temperature ranges are lower than automatic because the operator must touch the water and dishes at each step. This is evident in the lower sanitizing temp. or use of chemical sanitizers in cool water. Automatic sanitizing sinks are sometimes used where the operator wears safety gloves and lowers dishes in using a basket.

Mechanical Dishwashing Automatic Dishwashing Machine

Mechanical Dishwashing Steps o There are 6 steps: 1) Sorting Scraping Washing [pre-wash: 110 - 120°F, wash: 150 160°F] Rinse [160 - 180°F] Sanitize/Final Rinse [180 - 194°F] Air Dry 2) 3) 4) 5) 6)

Mechanical Dishwashing o o o Note the higher temperatures in the mechanical steps. The user only handles the dishes before and after they enter the machine, never touching the water. Dishes will always be AIR DRIED! They will also be much hotter coming out of a machine, so use care when handling or let cool.

Safety Tips o o o o Ensure protective covers are in place on all external moving parts Ensure side doors are closed Keep hands off the inside mechanism of the machine If a dish rack becomes jammed, turn off electric power and steam before removing the rack Wear rubber gloves and rubber aprons Report machine malfunctions immediately Wear hearing protection if required De-scaling of machines should happen weekly or as required.
