For how long are the grates in the Bird house replaced?

The grates in the Bird house are replaced every 4 hours to ensure optimal cleanliness and safety standards in the kitchen environment. Regular maintenance of grates helps in preventing any buildup of residues that could lead to contamination or flavor issues with food items. This timeframe is critical as it balances the need for cleanliness with the operational efficiency of the restaurant. Replacing the grates too frequently, such as every 2 hours or with every shift, might divert time and resources from other important tasks, while a longer duration like every day could allow for unsanitary conditions. Thus, every 4 hours is the appropriate interval for maintaining hygiene and operational functionality in the Bird house.
