— LOTO (lockout – tag out), secure, and disassemble equipment
— Remove gross soils from the equipment and floor
— Remove production supplies from the room
— Remove trash from the room
— Empty drain baskets
— Pre-sanitation task completed consistently (floors swept, equipment covered, materials removed, etc.)
— Equipment disassembled to proper level to provide accessibility
— Dry clean completed
— Remove remaining visible soils with hot water (90% to 95% as a benchmark)
— Gross soils prohibit effective surface cleaning if not removed prior to detergent application
— Water for pre-rinse should be hot – 120°F to 140°F
— Rinse until visually free of soils
— Use lowest effective pressure to minimize aerosols and condensation
— Lower pressure reduces risk of cross-contamination and machine damage
— Foam the walls, then the floor, and then the equipment
— Set contact time (i.e., 10 minutes) and do not allow detergent to dry because this may form a stronger soil
— Scour to remove films, fats, and proteins
— Clean drains
— Contact time, concentration, and mechanical action
— Scrub product contact surfaces daily
— Scour framework weekly minimum
— Chemicals are not a substitute for mechanical action
— Work from walls and floor to equipment
— Use designated brushes
— Clean with a designated employee at the end of his/her shift, just prior to sanitizing floor
— Use a chlorinated alkaline cleaner
— Clean all surfaces of the drain
— Sanitize with quat (800 ppm), iodine (75 ppm), or chlorine (800 ppm)
— Remove chemical and soils via flood rinse
— Rinse in the order the detergent was applied: walls, then the floor, and last the equipment
— Do not spray the floor once the post rinse of the equipment begins
— Use a flashlight to verify cleanliness; should occur throughout all steps
— 100% free of soils, hazes, or water beads; verify by sight and feel
— Put on clean outerwear
— Sanitize hands
— Verify all chemicals have been removed (sight, pH paper)
— Remove all standing water and overhead condensation
— Standing water prevents sanitizer contact with the surface
— Sanitize inaccessible parts prior to assembling
— Pre-op inspect parts that will not be accessible after assembling
— Assemble (follow LOTO procedures)
— Re-lubricate where needed
— Inspect to ensure free of chemicals, tools, and cleaning supplies before starting the equipment, and ensure that guards and safety mechanisms are in place
— Run equipment prior to inspecting
— Complete the formal pre-op spelled out in the plant’s SSOP
— Correct all deficiencies and provide feedback to the person responsible
— Pre-op the facility regularly for other deficiencies
— Make sure there is no standing water before beginning production
— Flood sanitize equipment—bottom to top (no rinse concentration) and make sure there is no standing sanitizer
— Equipment should be run to shed the sanitizer
— Foam sanitize entire processing area’s wall (5 ft. minimum) and floor (800 ppm quat minimum)
— Work your way out of the room
— Let air dry, squeegee pooling sanitizer
Let’s compare the costs associated with cleaning a grated trench drain system versus a slotted trench drain system.
A 100-foot section of grated trench drain is installed in a facility. The drain is load class rated to load E and is 100% stainless steel. The worker assigned to cleaning the drain earns $12 per hour and the drains are cleaned 5 days per week.
A 100-foot section of slotted trench drain is installed in a facility. The drain is load class rated to load F and is 100% stainless steel. The worker assigned to cleaning the drain earns $12 per hour and drains are cleaned 5 days per week.
Slotted trench drains are easier and faster to clean than grated trench drain systems. What’s the main difference between the drains? Slotted trench drains eliminate grates. It takes only 24-32 minutes to clean a slotted trench drain system, compared to the grated trench which takes 183-305 minutes to clean. The biggest advantage to switching to a slotted trench drain is the elimination in time it takes to lift, scrub, inspect and replace all the drain covers.
Your facility can save money in the long-term by switching to an easy to clean and maintain drainage system. Drains that comply with the USDA Sanitation Guidelines will feature smooth materials, radiused edges and stainless steel construction.
If drainage systems are difficult for employees to clean, the necessary cleaning procedures may be neglected. Poorly cleaned drains can harbour bacteria and lead to product recalls, fines, lawsuits or harm to consumers.
The best way to protect your food or beverage processing facility from contamination is by choosing a sanitary drainage system that complies with USDA sanitation requirements.
Slotted trench drains are providing drains that are easier to clean and are more cost-effective than grated trench drains. The linear slots eliminate traditional grates that are hard to clean and wear out within years. Slotted trench drains are applicable where ever floor or ground surfaces are subject to fluids or have frequent cleaning requirements.
Each Slot Drain® system includes a specially designed cleaning kit specific to its application. To clean the drain channel, cleaning kit options include an easy cleaning paddle, Flush FloTM System for frequent cleaning facilities.
