Choosing the Right Commercial Dishwasher: A Buyer’s Guide
Running a busy kitchen means you need a dishwasher that works fast and cleans well. A good commercial dishwasher saves time and keeps your dishes safe and spotless. This guide helps you pick the best machine for your business.
Key Features to Look For
Several features make a commercial dishwasher better. Think about how fast you need to wash dishes.
Wash Speed and Capacity
- Cycle Time: This is how long one full wash takes. Shorter times mean you wash more dishes quickly. Look for machines that finish a cycle in 1 to 3 minutes if your kitchen is very busy.
- Racks Per Hour (RPH): This tells you how many racks the machine can clean in one hour. High-volume restaurants need a high RPH number.
Temperature and Sanitization
You must sanitize dishes, not just clean them. This kills harmful germs.
- High-Temperature (Hi-Temp) Models: These use very hot water (usually 180°F or higher) for rinsing to sanitize. They need a built-in booster heater.
- Low-Temperature (Low-Temp) Models: These use chemical sanitizers mixed with the rinse water. They are easier on plumbing but require you to regularly check chemical levels.
Water and Energy Efficiency
These factors save you money over time.
- Water Usage: Modern machines use less water per cycle. Less water means lower utility bills.
- Energy Star Rating: Look for this label. It shows the dishwasher meets strict energy efficiency guidelines.
Important Materials and Durability
Commercial dishwashers work hard every day. The materials used greatly affect how long the machine lasts.
Stainless Steel Construction
The best machines use stainless steel for the body, tanks, and spray arms. Stainless steel resists rust and corrosion. It cleans easily too. Cheap plastic parts break faster.
Spray Arm Quality
The spray arms shoot the water onto the dishes. Metal spray arms are much better than plastic ones. They do not warp or clog as easily.
Factors That Improve or Reduce Quality
What makes one machine perform better than another?
Improving Quality Factors
- Powerful Pumps: Strong pumps ensure high water pressure. High pressure blasts away tough food soil.
- Advanced Controls: Digital controls offer precise temperature settings and easy troubleshooting.
- Self-Cleaning Features: Some high-end models automatically clean filters or drain tanks. This reduces daily maintenance time.
Reducing Quality Factors
- Poor Insulation: If the machine is poorly insulated, it loses heat quickly. This makes the machine use more energy to keep the water hot.
- Complex Repairs: If the machine is hard to open or service, repair costs go up quickly.
User Experience and Use Cases
Think about who will use the machine and where it will sit.
Types of Commercial Dishwashers
- Undercounter Models: These fit under a standard counter. They are great for small cafes or bars that do not wash huge amounts of dishes.
- Conveyor/Pass-Through Models: Dishes move through on a conveyor belt or you load them on one side and pull them out on the other. These are perfect for busy mid-sized restaurants.
- Flight-Type Models: The largest option, where dishes sit in specialized racks that move through the machine automatically. These are necessary for large cafeterias or hospitals.
Ease of Use
The machine should be simple to operate. Staff should not need a long training session. Clear indicators for water temperature and chemical levels improve daily workflow.
10 Frequently Asked Questions (FAQ) About Commercial Dishwashers
Q: How much power do commercial dishwashers use?
A: They use a lot of electricity and hot water. Energy-efficient models help lower these costs. Check the electrical specifications (like voltage and amperage) before buying.
Q: What is the difference between a booster heater and a built-in heater?
A: A booster heater is a separate unit that heats the rinse water to the very high temperatures needed for sanitizing (Hi-Temp models). Some low-temp models have a built-in heater that works with chemicals.
Q: Do I need special plumbing for these machines?
A: Yes. Commercial dishwashers need dedicated water supply lines and proper drainage. A qualified plumber should install them.
Q: How often should I clean my commercial dishwasher?
A: You should clean the filters daily. A deep cleaning or descaling might be needed every few months, depending on your water hardness.
Q: What is water hardness, and why does it matter?
A: Hard water contains many minerals like calcium. These minerals build up inside the machine, causing scale. Scale reduces heating efficiency and can break parts. A water softener is often recommended.
Q: Can I use regular dish soap in a commercial dishwasher?
A: Absolutely not. Commercial dishwashers require special, low-foaming detergents designed for high-pressure systems. Regular soap creates too many suds and can damage the machine.
Q: What size dishwasher should a small cafe buy?
A: A small cafe usually does well with a fast undercounter model that cleans 20 to 30 racks per hour.
Q: How long do commercial dishwashers usually last?
A: With good maintenance, a quality stainless steel unit can last 8 to 15 years.
Q: Are low-temp machines cheaper to run than high-temp machines?
A: Low-temp machines save on gas or electricity because they do not need to heat the rinse water as high. However, you must pay for the chemical sanitizers.
Q: What should I check if my dishes are still spotty?
A: First, check the water temperature settings. Second, ensure the rinse aid dispenser is full. Third, check that the spray arms are clean and spinning freely.
