There are different industries that handle residues in the form of ashes: bakeries, calcifiers, food, etc. All of them, sooner or later, face the problem of eliminating ashes of their ovens. Traditionally, this task was intended for chimney sweeps, who with the help of brushes cleaned the interior of ovens and chimneys of residues, but over the years they began to appear tools to supplant this degrading task: vacuum cleaners with ash filter.
Are ash vacuum cleaners They not only allow you to collect every last particle, but also allow you to work in optimal hygiene and safety conditions. Let’s know its advantages and what we can do with them.
What are ash filter vacuums?
They differ from vacuum cleaners common and industrial dry or wet vacuum cleaners in two important respects: the tank is completely metal – which reduces the risk of combustion – and they also have a very fine filter to prevent ashes are projected into the environment.
They are basically a large hollow metal cylinder, inside which the ashes collected by suction are deposited. A porous paper filter prevents the ashes from going back outside, thus remaining trapped inside the container.
There are two general models of ash vacuum cleaners: one is one vaccum cleaner itself, with an electric motor, specialized in this type of particles. While they can be used for any other dry vacuum job, they are primarily used for cleaning industrial ovens. They are recommended for industries or large kitchens that require frequent cleaning.
The second model is cheaper, since it simply consists of the filter, the container for the particles and the hose; to be able to operate with them it is necessary to have a traditional vacuum cleaner, which is connected to the container through a second air intake; the suction created by this makes the system work, and the ash particles are trapped in the container without reaching the vaccum cleaner.
Why is it necessary to have a specialized ash filter vacuum?
First there is the question of safety: it may happen that some small portion of the ash is still hot enough to melt plastics; in this case, the metal container protects the user and the rest of the appliance from the heat generated.
It also protects the suction pump and other mechanisms from filling and abrasion caused by ash particles, which are abrasive in many cases.
In a vaccum cleaner Traditional aspiration is produced through a porous cloth bag that, upon receiving ashes, begins to clog, with which, after a while, it is no longer possible to filter the air, thus making the vacuum cleaner less effective. The HEPA filter of these vacuum cleaners It prevents the particles from sticking and falling into the metal container.
The particulate-laden air enters the particulate storage tank after being collected by the reinforced hose. A nozzle, installed in the upper part, sucks the internal atmosphere. This, however, is forced to pass through a microporous filter installed at the inlet of said nozzle.
The particles cannot pass through the sieve and are retained there, precipitating, due to the impact of other particles, to the bottom of the tank, where they remain until later discarded by the user, once the machine is turned off.
Main Uses for Ash Filter Vacuums
- Grill cleaning.
- Cleaning smokehouses, where the wood ashes are deposited.
- Cleaning of fireplaces and salamanders.
- Cleaning the wood-fired ovens.
- Cleaning of small smelting furnaces where charcoal is used.
Uses in industry
- Setting up large grills in restaurants and food stalls on the go.
- Deep cleaning of pizza ovens, bakers and other related ovens, where the calcined particles of the food product are deposited.
- Cleaning of solid combustion boilers.
- Cleaning of smoke boxes, fire beds and steam locomotive boilers.
- Commissioning of brick and clinker kilns.
- Cleaning incinerators of pathological waste disposal centers.
- The opening of the drum must only be done with the appliance stopped, turned off and unplugged, to avoid risks of electrocution.
- Use filters compatible with the make and model; The use of other filters can not only result in a faulty aspiration; You can also put the vacuum cleaner and your health at risk by projecting particles outside.
- Never try the ash aspiration with your common household vacuum cleaner; Particles will clog filters and cause engine damage. Instead use the fine filters, which allow you to connect your vacuum cleaner through a nozzle, and are used as vacuum intermediaries.
- Wear a chinstrap at all times, and goggles. If for any reason you trip over the storage drum and it opens, the particles will invade the atmosphere, causing breathing problems.
