WHAT IS A VENDING MACHINE?

A vending machine is actually an automatic machine which dispenses or release small food items and other articles such as chips, cans, candies, chocolates, milk, charger, cigarettes, cigars and other upon inserting a token or a coin. A vending machine is mostly found at hospitals, public places, malls, colleges, schools, even at petrol pumps and at the train stations and airports.

A vending machine is very advantageous for the ones who get hunger pangs on their way home, or at school or waiting for someone at the hospital. Moreover, vending machine is very easy to use. However, you need to have money in the form of coins to dispense the food articles that you want.

One big disadvantage of the vending machines is that vending machines are noisy when dispensing and releasing food and other articles. Manufacturers are striving hard to make the vending machines quiet.

Here are some questions on how to make a vending machine quieter:

HOW TO MAKE A VENDING MACHINE QUIETER

Vending machine use speed reducers which dispense the food articles for the by stander. However, the irritating noises are result of the function of the speed reducers in the vending machine. To reduce the vending machine’s noise, it is better to keep maximum decibel level during the dispensing operation.

Manufacturers should keep the range between 40 to 50 decibels. Moreover, the manufacturers should also put the vending machine to function according to the calculated weighted frequency range.

HOW CAN I REDUCE NOISE FROM MY MACHINE?

There are many ways in which you can reduce noise from your vending machine.

These ways include installing noise compressors to compress the noise coming from the vending machines. The other option is to invest in fan bearings.

Fan bearings reduce the friction, hence reduces the noise coming from the vending machine upon dispensing the food articles.

Some of the older type snack vending machine have these fan bearings located at the back of the vending machine and in time this will cause so much unwanted noise.

I simply unplug the molex connector to the fan of the snack machine causing the noise and it solved the problem. See the pictures below on how to locate the fan on your snack machine.front of snack machine

When the snack machine is opened you will see the fan which is normally located on the right most top portion of the snack vending machine as depicted on the picture above. You just have to simply disconnect the power cable on the left or right side which is attached on the fan to solve the noise problem.

WHAT MATERIALS CAN BLOCK SOUND?

You need to replace your fan motors in the vending machines in order to reduce the noise coming from them. One way is to replace the components and the other way is to install noise reducers. Noise reducers include fan bearings next to the fan motors, noise compressors or even a new compressor to suppress the noise coming from the vending machine.

WHAT MATERIALS ABSORB THE SOUND OF THE VENDING MACHINE?

The materials which absorb the sound of the vending machines are sound insulators.

They are basically batts that are made from rock wool, mineral wool and fiber glass that are fit into the machine and in between the studs of the walls.

Another material is the floor underlayement. It is the material that soundproofs the floor to reduce the transmission of noise from the vending machines.

CAN I CHANGE ANY PART IN THE VENDING MACHINE TO REDUCE NOISE?

Sometimes, the vending machine also makes noise because of the old compressor. You can put in or replace the new compressor. The new compressor can reduce the noise from the speed reducers. This can reduce the noise from the vending machine while the machine dispensing the food articles.

AT WHICH FREQUENCY VENDING MACHINE WILL MAKE LESS NOISE?

Speed reducers work according to their normal duty cycles. The level meters of sound determine the frequency which range between A to Z. The audible frequency ranges from 500 Hertz to 6 kilo hertz.

CAN THERMAL TREATMENT MAKE VENDING MACHINE QUIETER?

Apart from the noise barriers and the sound proofing materials, the thermal treatment of the vending machines can also make the vending machines quieter but this treatment does not absorb all of the noise.

SHOULD I GET VENDING MACHINE REPAIRED TO REDUCE ITS NOISE?

Sometimes, the vending machine also makes noise because of the damaged compressor. Getting it repaired can also help to reduce its noise.

I used to have a noisy Coke Soda Pop machine and it was creating some noise in the lunchroom and the management decided to have it taken away on two of my locations as I have recalled.

It is imperative to have noisy vending machines fixed.

CONCLUSION

Manufacturers are finding latest ways and viral technologies to reduce the noise from the vending machines. However, there are still some ways through which the noise can be reduced to some extent.
