The hood-type dishwasher is not only used to wash dishes, but also has functions such as sterilization and disinfection; because of this, the hood-type dishwasher is increasingly loved and purchased by commercial kitchens such as the catering industry. So how do you use the newly purchased hood-type dishwasher? Let the SHINELONG editor explain it to you below. The operation process of the hood-type dishwasher 1. Turn on the machine: open the main water gate → turn on the power gate → check whether the machine door is closed → turn on the machine → preheat for 20 minutes. 2. Pre-wash: remove stains → soak tableware → plate frame → cup frame → small pieces frame → shower rinse. 3. Washing, disinfection and drying: push the frame into the machine → close the door to start washing → wash, disinfect, and dry → spray out of the frame → tableware into the cleaning frame → turn off the machine. 4. Stop: turn off the power gate → remove the basket bracket → remove the drain tank → remove and clean the filter → clean the inside of the machine → install the filter, drain tank, etc. Working principle of hood-type dishwasher 1. The bowl frame is fixed in one position during operation, and the computer program controls the various functional parts to perform corresponding spraying, rinsing (using enzyme detergent, which can efficiently decompose and peel off stains, without foam, and not resistant to high temperature) and other tasks within the set time period. First, the boiler heater heats the clean water connected to the boiler to 82℃--85℃ for rinsing the bowl frame during the rinsing stage. At the same time, the pool heater is controlled to heat the circulating water in the pool to 55℃--60℃ for the main washing spray. The rinse water automatically flows into the pool and is mixed with the main wash spray water for recycling, and the used sewage overflows and is discharged through the overflow pipe. 2. During rinsing, the rinse arm rotates and rinses under the reaction force of the rinse water flow. The size of the water circuit pressure affects the rinsing and flushing impulse and rotation speed. Therefore, in order to ensure the washing effect, users with low water circuit pressure and a booster pump is added in the water circuit to increase the water pressure. The main wash spray is completed by pumping water and pressurizing. 3. During the washing process, the program sets three washing cycles for users to choose from. Each cycle is divided into the main wash spray time, the 4-second pause time, and the rinse time. During the main wash spray, it can provide a signal to the detergent dispenser to work, and during the rinse, it can provide a signal to the drying agent dispenser to work. In fact, the use of the hood dishwasher is very simple. After confirming that the machine is working properly before starting, just press the power on/off button on the front control panel. In addition, the reasonable operation and use of the hood dishwasher is beneficial to the service life of the hood dishwasher and improves work efficiency. The above is the introduction of the use process of the hood dishwasher by SHINELONG editor. If you encounter other problems or questions, you can pay attention to and contact SHINELONG! .
