Oblong Chafing Dish Features:

Daily cleaning and maintenance:

After each use, the Oblong Chafing Dish should be cleaned thoroughly immediately. First, remove the remaining food thoroughly. You can use a soft scraper to gently scrape off the food residue. Avoid using hard metal tools to prevent scratching the stainless steel surface of the dish. Then, use warm water (the water temperature is controlled at 40-50℃) and neutral detergent for preliminary rinsing. The soaking time is 10-15 minutes to loosen the stains attached to the surface. Next, use a soft sponge or nylon brush to gently scrub the inside and outside surfaces of the dish. For stubborn stains, such as burnt oil stains or soup, you can use a special stainless steel cleaner. Dilute it according to the ratio of the detergent instructions (usually a ratio of 1:10 detergent to water) and apply it to the stain. Let it stand for 3-5 minutes before scrubbing. It can effectively remove stains without damaging the surface of the dish. After scrubbing, rinse thoroughly with clean water to ensure that there is no detergent residue. Finally, wipe the moisture on the surface of the dish with a clean and soft rag to avoid water stains remaining on the stainless steel surface during the natural drying process to form scale, which will affect the beauty and service life of the dish. After such a daily cleaning process, it can be guaranteed that the Oblong Chafing Dish can maintain a good hygienic state after each use, prepare for the next use, and extend its service life.

Regular deep maintenance:

In addition to daily cleaning, deep maintenance should be performed once a week. First, check and clean the heating element. Turn off the power and unplug the plug. After the heating element is completely cooled (usually 30-45 minutes), use a clean soft brush to gently clean the dust and oil on the surface of the heating element. For dirt that is difficult to clean, you can use a special electrical cleaner, spray it on the surface of the heating element, wait for 5-10 minutes, and then wipe it gently with a soft cloth, but be careful to avoid liquid from entering the heating element to prevent short circuit or damage. At the same time, check whether the connection line of the heating element is loose or has signs of damage. If it is loose, it needs to be tightened in time. If it is damaged, contact a professional maintenance personnel for replacement. Secondly, calibrate the temperature control system. Use professional temperature calibration equipment to place the probe inside the Oblong Chafing Dish, set different temperature values (such as 60℃, 70℃, 80℃), and observe the deviation between the actual measured temperature and the set temperature. Generally, the deviation range is required to be controlled within ±2℃. If the deviation exceeds this range, the temperature control system needs to be adjusted, which can be achieved by adjusting the calibration knob of the temperature control system or replacing components such as the temperature control sensor. Regular in-depth maintenance can ensure that the heating and temperature control performance of the Oblong Chafing Dish is always in the best condition, improve the stability and reliability of the equipment, and reduce the risk of interruption of catering services due to equipment failure.

Storage and maintenance:

When the Oblong Chafing Dish is not used for a long time, such as the off-season of the restaurant or the idle period after the equipment is replaced, it needs to be properly stored and maintained. First, make sure that the dinner plate has been thoroughly cleaned and dried to prevent residual moisture and stains from breeding bacteria or causing rust on the stainless steel surface during storage. Then, apply a thin layer of edible-grade anti-rust oil on the surface of the dinner plate. This anti-rust oil can form a protective film to isolate moisture and oxygen in the air, effectively preventing the stainless steel from oxidation and corrosion during long-term storage. Then, place it in a dry and ventilated storage room to avoid contact with acidic, alkaline or corrosive substances. At the same time, place a soft wooden board or foam board under the dinner plate to prevent moisture and hard objects on the ground from damaging the bottom of the dinner plate. In addition, the dinner plates should be stacked neatly one by one during storage, but the stacking height should not exceed 10 to avoid deformation of the dinner plates due to excessive pressure. During storage, check at least once a month to check whether there are any abnormal changes on the surface of the dinner plate, such as whether the anti-rust oil falls off, whether there is rust on the surface, etc. If there is any abnormality, it needs to be handled in time, re-apply anti-rust oil or perform rust removal to ensure that the equipment can work normally when it needs to be used again, and avoid economic losses caused by equipment damage due to improper storage.

Appearance maintenance:

In order to maintain the beautiful appearance of Oblong Chafing Dish, regular appearance maintenance is required. For water stains on the surface of stainless steel, you can use a special stainless steel brightener, spray it evenly on the surface of the plate, and gently wipe it with a clean and soft non-woven cloth in a circular motion. This can effectively remove water stains and restore the surface gloss. The area wiped each time is controlled at about 30*30cm, ensuring that the wiping is even and no scratches are missed. For minor scratches, you can use a stainless steel scratch repair agent. According to the requirements of the product manual, apply the repair agent to the scratch and gently polish it with the attached polishing pad. After treatment, the glossiness of the scratch can be restored to 80% - 90% of the original, making the surface of the plate look more beautiful. At the same time, be careful to avoid using detergents containing chlorides to clean the surface of the plate, because chlorides will react chemically with stainless steel, causing surface corrosion and discoloration. Regular appearance maintenance can not only enhance the overall image of the Oblong Chafing Dish, making it more attractive in catering venues, but also extend its service life to a certain extent, because a good appearance condition can reflect the maintenance level of the equipment and indirectly reduce the risk of internal structural damage caused by surface damage.

Parts replacement and maintenance:

During use, some parts of the Oblong Chafing Dish may be worn or damaged and need to be replaced and repaired in time. For example, the anti-slip rubber sleeve of the handle may be worn or aged after long-term use. When the wear degree of the anti-slip rubber sleeve exceeds 1/3 of its thickness, it is easy to cause the waiter to slip during the grip. At this time, it is necessary to replace the new anti-slip rubber sleeve in time. When replacing, you should choose the product with the same specifications as the original factory to ensure that the handle is comfortable and firm to hold after installation. For the heating element, if the heating speed is found to be significantly slower or unable to reach the set temperature during use, after checking and confirming that the heating element is damaged, you need to contact professional maintenance personnel for replacement. When replacing, pay attention to the power and specifications of the new heating element must match the original equipment, otherwise it will affect the heating performance and service life of the equipment. During the maintenance process, strictly follow the maintenance manual of the equipment to ensure that the performance indicators of the equipment after maintenance meet the standards. At the same time, it is necessary to establish a record of equipment component replacement and maintenance, and record in detail the time, component name, reason, and component information after replacement for each replacement and maintenance. This will help understand the use status and life of the equipment, provide a reference for future equipment updates and maintenance, ensure that Oblong Chafing Dish is always in good working condition, and provide reliable protection for catering services.

Environmental adaptability maintenance:

Oblong Chafing Dish requires corresponding maintenance measures in different seasons and environmental conditions. In winter, when the equipment is transferred from a low temperature environment (such as an outdoor warehouse or transport vehicle) to a warm indoor environment, condensation will occur. At this time, the equipment should be left to stand in the indoor environment for 1-2 hours, and then powered on after its surface temperature gradually returns to room temperature, so as to avoid damage to internal electronic components due to moisture caused by excessive temperature difference. At the same time, when used in winter, due to dry air, the moisturizing treatment of the stainless steel material on the surface of the equipment can be appropriately increased, such as applying a thin layer of edible grade grease once a week to prevent tiny cracks on the stainless steel due to dryness. In summer, especially in humid environments, care should be taken to prevent mold growth on the surface of stainless steel. In addition to thorough cleaning after each use, you can sprinkle a small amount of desiccant (such as silica gel desiccant) on the surface of the plate and remove it before the next use. This can effectively absorb residual moisture and reduce the risk of mold growth. When using the equipment in coastal areas or humid basements, pay more attention to moisture and salt spray corrosion. In addition to daily cleaning and regular maintenance, you can use a professional stainless steel preservative to perform a comprehensive protective treatment on the equipment every month. According to the requirements of the preservative manual, apply it evenly on the surface of the equipment, keep it for 30-60 minutes, and then rinse it with clean water. This can enhance the corrosion resistance of the stainless steel material, extend the service life of the equipment in harsh environments, and ensure that it can stably and reliably provide support for catering services under various environmental conditions.
