Industrial washing machines: How to choose?

Industrial washing machines are essential to increase productivity in restaurants, catering, healthcare, and retail establishments. Meeting the specific needs of these sectors requires washing equipment capable of washing large volumes of utensils in a fast, safe, and sustainable way. These are the key advantages of industrial washing machines, how to choose one, and the technologies revolutionizing the field.

What are industrial washing machines?

Industrial washing machines, such as the MultiWasher developed by Somengil, are equipment specifically designed for commercial or industrial environments, such as hotels, factories, hospitals, or restaurants. They are larger and more powerful than domestic washing machines and can sanitize large volumes of utensils, such as containers, trays, instruments, tools, components, and many other items. Industrial washing machines have a solid, rugged, durable construction to withstand the wear and tear of frequent use and to provide the stability and support needed for efficient and effective performance.

Rather than depending on manual labor to wash and dry large quantities of items, industrial washing machines reduce the time and effort required so employees can focus on more complex tasks. In addition, companies reduce the human errors, incomplete sanitizing, and supervision.

What are the features of industrial washing machines?

These are the most common features of industrial washing machines.

High load capacity

Industrial washing machines are designed to sanitize large quantities of utensils at once, which means they can wash a higher volume of items in fewer cycles.

Specialized Wash Cycles

Industrial washing machines can be programmed for specific wash cycles depending on the type of utensils to be sanitized. This feature ensures that utensils are washed according to their nature and specifics, ensuring more effective results.

Automatic dosing system

Some industrial washing machines have an automatic dosing system that measures the exact amount of detergent and other products for each wash. This ensures that only the strictly necessary resources are used, avoiding waste.

Disinfection systems

Disinfection systems can be found in some industrial washing machines that use specific disinfectants to eliminate bacteria and other microorganisms that can be harmful to health. This feature is especially important in sectors such as healthcare or food.

Automatic drying

Some industrial washing machines have a built-in drying feature, such as industrial washing machine and dryer, which means that utensils can be washed and dried in a single operation. As a result, items come out of the machine ready to use.

Energy-saving mode

The most advanced industrial washing machines have energy-saving features, such as sensors that detect the number of items in the machine and adjust water and energy consumption accordingly. This reduces operating costs and makes the process more environmentally friendly.

Water recovery systems

The latest machines have water recovery systems that filter and reuse residual water from the wash in future cycles. This reduces water consumption and waste.

Remote programming

Some industrial washing machines can be programmed remotely via a centralized management system. This feature allows users to monitor and control the wash without being physically near the machine.

Maintenance Features

The latest industrial washing machines have maintenance features, such as service alerts and diagnostics, that help users identify and correct problems before they become serious and force the machine to stop.

What are the advantages of industrial washing machines?

Increased washing quality, productivity, sustainability, cost reduction, time savings, increased safety, and compliance with legislation – industrial washing machines have several key benefits worth exploring.

1. The industrial washing machine ensures compliance with legislation, in every wash

Every food business is obliged to comply with country-specific food regulations. With an industrial washing machine, companies ensure that all utensils and equipment are sanitized and dried properly, within the legally required sanitation parameters:

• Preparation – equipment that will be needed for cleaning and production actions must be disassembled to ensure that it is properly sanitized.
• Dry cleaning – refers to the manual removal of any larger waste, usually with the help of brushes or other utensils. This practice prevents large particles from contaminating the water used in the washing process, as well as potential problems such as clogged pipes or wet solid waste handling.
• Pre-rinse – the surface of the objects should be pre-rinse with cold water at low pressure to remove residues that are loosely adhered to the surface.
• Cleaning – the stage when moistening occurs and the cleaning agents penetrate the equipment and surfaces, as well as the dirt itself. The efficiency of the cleaning process depends on the contact time, temperature, type of dirt and quantity of water.
• Rinsing – after the cleaning stage, rinsing ensures the removal of cleaning residues and dirt, again using water.
• Disinfection – after the surfaces are clean, it is time to disinfect the equipment and surfaces, which is only possible when the detergent is removed completely. This is the last step, which kills off microorganisms that can be harmful and contaminants to the environment, surfaces, hands, and food.

2. Using an industrial washing machine contributes to food safety

An industrial washing machine combines biodegradable detergents with water at high temperatures (over 65°C) to remove grease residues, dirt, germs, and bacteria. In this way, it contributes to greater food safety compared to traditional manual processes.

3. An industrial washing machine saves water, energy, and detergent

Unlike manual wash, an industrial washing machine can control the amount of water, detergent, and energy required for each wash cycle. As a result, modern, energy-controlled smart washing machines, such as the MultiWasher, consume 2/3 less water and use 70% less detergent than the traditional washing process.

4. Washing automation frees people for value-added tasks

Another benefit associated with the industrial washing machine is its efficiency. The level of automation of state-of-the-art washing equipment means that large quantities of utensils (dishes, tools, trays) can be sanitizied in a short period. Automation frees up employees to focus on other higher value-added tasks.

5. Following optimal washing parameters increases utensils’ lifecycle

When washing follows optimal parameters of temperature, water, duration, and speed, it can add to the durability of objects. The chemical effect of the detergents, the force applied and the duration of the process – these are all factors in the lifecycle of crockery and tools.

What types of industrial washing machines are there?

There are several types of industrial washing machines, each designed to meet the specific needs of different types of commercial and industrial facilities.

Industrial high-pressure washing machines

These machines use high-pressure water jets. They are generally used in industrial facilities, such as factories and workshops, to clean parts, tools, and equipment.

Industrial immersion washing machines

This type of machine uses immersion recipients to wash parts and equipment. They are also commonly used in workshops, factories, and other places where parts need to be thoroughly sanitized.

Industrial tunnel washing machines

These machines are used to wash large volumes of work pieces and equipment. The pieces are fed into one end of the machine and passed through a series of washing stages before being discharged at the other end.

Closed Cabin Industrial Washers

Closed cabin industrial washing machines are designed to wash industrial parts and components with high efficiency and productivity. As the name suggests, they have a single enclosed area where all the washing steps take place. The process is thus isolated from the external environment, making it safe, controlled, and automated. In addition, they take up less space and a smaller area. It’s the case of the MultiWasher, the latest generation industrial washing machine developed by Somengil, an innovative step in hygienization in industries of several sectors.

How to choose an industrial washing machine?

Performance, consumption, size, capacity – there are many factors to consider when choosing an industrial washing machine.

Size and capacity

Industrial size washing machines are used in commercial and industrial settings where a high-capacity and heavy-duty solution is required. So, industrial size washing machines should be adapted to the space available and the volume of utensils that need to be washed daily. The choice will be different for each specific case, but these are some guidelines for each type of business:

• For small establishments, restaurants, and cafes. A standard industrial washing machine with a capacity to wash 35 racks per hour may be enough;
• For food and retail industry. The workload in these industries is much larger in scale, so industrial washing machines should be capable of at least washing about 3,000 dishes per wash.

Temperature

When procuring an industrial washing machine, it is important to consider the temperatures at which utensils will be washed. High temperatures ensure complete sanitation by eliminating organisms. According to food industry’s best practices created by the Portuguese General Directorate of Health, dishes and other utensils should be washed in an industrial washing machine at temperatures ranging from 80 to 90 degrees Celsius.

Water consumption

Water consumption is one of the most important decision factors – both to reduce operating costs and to minimize the environmental footprint of the washing process. Water consumption is measured in gallons of water per wash cycle. On average, industrial washing machines consume about 23 liters of water.

To reduce this figure, look for equipment that can recycle water. With this feature, water from one washing cycle is purified and used for the next cycle. The MultiWasher is equipped with a recycling system which reduces consumption to only 7 liters per cycle, about 70% less than what is offered in the market.

Energy consumption

With electricity accounting for 11% of the industrial energy consumption, it is essential that companies create strategies to save this resource. Choose an energy-efficient washing equipment with several “modes” of operation – eco, smart or low-cost. Selecting a machine with these features can reduce electricity consumption by up to 50%.

Detergent consumption

Besides consciously choosing ecological detergents free of inorganic substances such as phosphate, it is also crucial to select a machine that makes reasonable use of such products. For instance, when the MultiWasher runs a normal washing cycle, it uses 70% less detergent than other industrial washing machines.

Wash quality

Washing quality should be a key criterion in the procurement decision. It can be measured by the amount of light generated by adenosine triphosphate (ATP), an energy source present in animal, plant, bacterial, and fungal cells.

The smaller the amount of light generated by a particular utensil, the cleaner it is. There are reference values for the units of light generated by clean utensils in each industry:

• In the Food area, the maximum is 500 units of light. A result above this limit indicates an unsafe concentration of organisms;
• In the Healthcare sector, requirements are naturally tighter – disinfection of clinical consumables in hospitals requires a maximum of 100 light units (except in operating rooms, where it is even more stringent).

Ergonomics

Prioritize equipment that supports the specific needs of your workflow. It is important to have a fully ergonomic machine with wash carts easy to load and unload, therefore requiring less effort and time spent by employees.

Noise

Noise is another essential factor in an industrial washing machine. In production environments that are naturally noisy, either from handling of kitchen utensils or other machines, it is essential to choose quiet equipment. A high noise level at the workstation reduces concentration, increases anxiety, and can even alter the natural sleep cycle of employees.

Data logging

In a 4.0 world, industrial washing machines should integrate a system capable of recording the washing cycles and parameters used, so that this data can be used to identify patterns and plan future improvements.

Ease of use

Every machine should be intuitive for its operator. Equipment with simple dashboards makes it possible to select pre-recorded programs and schedule washing, disinfection, and decarbonization times that make daily production much faster and more efficient.

Stainless steel washing machine

Industrial washing machines, handling large volumes of items in diverse settings, are exposed to harsh chemicals and detergents. Stainless steel’s exceptional corrosion resistance ensures that components are unaffected by these aggressive substances over extended periods, contributing to the longevity of the appliance.

Moreover, washing machines are subjected to heavy loads and frequent use. Stainless steel washing machines are known for its strength and durability, withstanding the rigors of continuous operation and the mechanical stresses associated with large and heavy loads. In addition, stainless steel washing machines can handle high temperatures without compromising its structural integrity.

What is the origin of industrial washing machines?

Every story has a beginning. The story of industrial washing machines began more than 250 years ago. With the industrial revolution, factories of every kind sprang up. But, discreetly and hundreds of kilometers away from the industrial centers of Birmingham and Manchester, a discovery was being made that would change the lives of millions of people all over the world. In quiet, green Ratisbonne, Germany, Jacob Schäffer successfully tested the first washing machine in 1767.

The first step towards the industrial washing machine had been taken. However, it would take almost 100 years for Joel Houghton to create a machine closer to those we know today – a wooden contraption with a crank that sprayed water onto the dishes. It took even longer for Josephine Cochrane to introduce the first truly functional washing machine. An engineer’s daughter, she surprised the world with a dishwasher design very similar to the one we know today. Patented in 1886, it had wire shelves to keep kitchen utensils in place.
