What should we look for when choosing the commercial dishwasher?
1. Temperature
There are two classifications of dishwashers: high temperature and low temperature. The way to distinguish this is to confirm whether the washing water temperature is higher or lower than 160°F. A dishwasher with a value higher than this is a high temperature dishwasher, and the opposite is a low temperature dishwasher. All of the above dishwasher types have the distinction between high and low temperature, and each of these two temperatures has its own advantages and disadvantages. You can consider them all after detailed understanding.
Most commercial dishwasher on the market choose high-temperature cleaning, because the high-temperature water flow can play a rapid dissolution of oil and grease and the role of the initial sterilization, while the residual temperature of the dishes after the end of the cleaning can also be faster to make the surface water beads evaporate. Its disadvantage is that heating will consume more energy.
Low-temperature dishwashers use chemicals to help dissolve grease and sanitize, and because they do not use heat, they consume much less energy, but the disadvantage is that the chemicals may cause slight residue or corrosion on the surface of the dishes.
In terms of cost, a high-temperature dishwasher requires a matching heating unit and additional energy costs, while a low-temperature dishwasher requires more costs for chemicals, making it more expensive overall.
2. Size
If you have a limited kitchen area or only need to handle a small amount of dishes per day, then an undercounter dishwasher is the right choice, while if you are serving more than 100 people, you need to consider a larger dishwasher. In order of ranking by washing volume, from lowest to highest are undercounter dishwasher, hood type dishwasher, conveyor dishwasher, and flat type dishwasher.
It is important to note that you first need to choose based on the highest daily traffic data to ensure that the dishwasher can withstand the impact of peak traffic periods. If your business growth trend is significant, you will need to choose a larger capacity dishwasher from the current one, otherwise, as time grows, a dishwasher with insufficient capacity will soon be unable to adapt to the needs of the kitchen.
3. Noise
Commercial dishwashers are large pieces of kitchen equipment, and the sound of high pressure pumps running and water pounding can affect the overall environment (even if they seem to be an insignificant part of the commercial kitchen environment). Working in a noisy environment can affect the mood and even the health of employees, and this advice is not limited to dishwashers, but is also appropriate to be considered when shopping for all commercial kitchen equipment.
If you want to maintain a good kitchen environment, you need to check whether the equipment uses a low-noise engine/pump or is soundproofed as a whole. For commercial dishwasher, which need to be sealed during operation, simply adding soundproofing foam to the panels can block out most of the noise. Ultrasonic dishwashers are recognized as the least noisy because they do not require the use of high-pressure pumps.
4. Speed
The speed of the dishwasher is directly related to the business situation (it is very difficult to prepare enough dishes to be washed uniformly after the business ends), even if the capacity of the dishwasher is not large, as long as it can wash fast enough, it can bear the impact of the whole peak traffic. The ideal cleaning speed is only 45s, and most dishwashers are able to adjust the cleaning cycle, the slowest cleaning time is not more than 3 minutes.
And there are times when you don’t have to be so strict about speed: when customers are taking longer to eat. Fast food has much more demand for dishes at peak times than fine western food.
5. Energy Costs
Choose a dish washing machine with an Energy Star label or heat recovery device, they can save more energy. In addition, even though dishwashers generally use less water than manual cleaning, you still have to be concerned about how much water they use to clean a rack, which commonly ranges from 1.7L-4L, and choosing a water-efficient design can also help save money.
Similarly, if you need to choose between a high-temperature dishwasher and a low-temperature dishwasher, it’s a choice between energy costs and chemical costs. High-temperature dishwashers use more energy to heat, and low-temperature dishwashers cost more to purchase chemicals.
Conclusion
Dishwashers vary greatly in their focus and cleaning capacity, and the easiest way to decide is to refer to this article based on the number of restaurant diners and the type of dishes to be cleaned. In addition, the type of racks is often overlooked, and choosing different racks for different dishes can increase the cleaning effect. For example, glass racks for goblets and cup racks for mugs, or larger racks for pots and pans, can be more effective.
Choosing the right commercial dishwasher is not an easy task, there are many aspects to consider and I hope this article will help you and your business.
