Review of dishwasher MMU 1000M

PMM MMU 1000M Large canteens, hotels, fast food restaurants with a huge traffic volume need a reliable and efficient dishwasher. In this case, you need equipment capable of washing no less than 1,500 plates per hour, and such equipment is produced at the Grodno Commercial Engineering Plant. Today we will talk about the MMU 1000M dishwasher, a review of which we have prepared for you.

Purpose of the machine

It's very powerful conveyor type dishwasher, capable of washing up to 1600 dishes per hour. It is intended for large catering establishments with more than 300 seats. MMU 1000M is equipped with two types of cassettes that allow you to wash both standard and non-standard dishes, kitchen utensils, and cutlery. The equipment can be connected to hot water or cold water.

When connecting the machine to cold water, we reduce the life of the heating elements.

The MMU 1000M is serviced by two kitchen workers. One is engaged in loading and installing cassettes with dirty dishes, the other takes out clean dishes from the cassettes and puts them in storage areas. During operation, the machine is capable of:

pre-wash;
treating dirty dishes with a washing solution;
pre-rinse with very hot water, heated to 85⁰WITH;
final rinse with water without heating.

Main characteristics

What are the technical characteristics of the best brainchild of the GRODTORGMASH company? We have already said about the productivity of the MMU 1000M, 1600 plates per hour. But this is the so-called theoretical performance.In the kitchen, in addition to standard plates, there are bowls, glasses, ladles, cutting boards, baking sheets, trays and much more.

The performance of a machine for a specific dish can only be calculated experimentally. However, companies that use MMU 1000M machines speak very highly of them, confirming their reliability and high productivity. We note that the size of the dishes should not be larger than 530x325 mm, otherwise they will not fit in the cassette and it will be impossible to wash them automatically. So, the characteristics.

The machine is made of the highest quality stainless steel.
When using cold water, the machine consumes 32.8 kW/h, when using hot water 24 kW/h.
Connects to a 380 V industrial power supply.
During continuous operation, the machine consumes an average of 200 liters of hot water.
Machine size W x D x H – 1050 x 3700 x 1300 mm.
The mass of the MMU 1000M with all units is 525 kg.
Estimated service life is 8 years.

Components

The MMU 1000M universal dishwasher is a rather complex unit. The machine consists of many parts that provide it with unsurpassed functionality. The MMU 1000M consists of a number of elements, starting from the loading section and ending with the ventilation pipe, but it is not thanks to these elements that the machine outperforms its closest competitors, but thanks to the electrics. The unique electrical circuit of the machine consists of a number of parts.

Temperature sensors type 03.03.300 in the amount of 3 pieces.
There are 3 capacitors.
Tubular heating elements for 3000 W222 in the amount of 3 pieces.
Tubular heating elements for 4000 W212 in the amount of 6 pieces.
Two fusible links.
Semiconductor lamps 3 pcs.
Relays and contactors – 13 pcs.
Engines – 3 pcs.
Electric pump with starting capacitor.
Two dispenser pumps.
Three-pole circuit breaker.
11 switches of various types.
Resistors, surge suppressors – 14 pcs.
Thermal switch and thermostat.
Level sensors – 8 pcs.
Two microswitches.
Transformer.
Triac VT B08-600BW
Two solenoid valves and terminal block.

Usage

Before starting the MMU 1000M dishwasher, it is necessary to properly equip the cassettes with dirty dishes. Blue cassettes are for glasses. They have special oblong cells. Green cassettes are more versatile. They can even be used to wash cutlery. The dishes fit tightly. Cassettes with cutlery must be covered with a special mesh.

We pour the detergent into a special reservoir, install the cassette on the conveyor and start the dishwasher. Passing through the tunnel part, the dishes are completely washed and rinsed. All that remains is to pick up the cassette from the conveyor at the exit. Operating the machine without loading for more than 10 minutes is not allowed.

So, on the Russian market it is difficult to find a dishwasher that would beat the MMU 1000M dishwasher in terms of characteristics and price. By the way, it costs only $7,500, while its closest competitor is $2,000 more expensive. It's worth thinking about.
