ACS Cleaning effectively clean animal feed silo for major organisation

One of the UK’s leading providers of agricultural and rural supplies contacted the dedicated team at ACS Cleaning to have one of their animal feed silos rigorously inspected and cleaned. The ACS Cleaning team were happy to take on the task, and subsequently sent three highly trained rope access and confined space technicians to complete the process.


Firstly, an inspection had to be carried out to look for the cause of a blockage within the silo preventing the flow of feed into the production plant. Once any blockages had been identified, they were cleared by our specialist cleaning team.

In particular, the three-member team were asked specifically to look for and provide:

  • Cause for the loss of flow from the silo.
  • Moisture build-up and contaminated product within the dead space area.
  • Any damage present and/or foreseeable problem areas.
  • A dry clean and brush down internal surfaces and remove the blockage.
  • A photographic record of the condition of the silo and of any work carried out.

With around two tons of product removed in total, the ACS Cleaning team identified that the blockage/hang-up was located around the bottom cone section of the silo structure. The product had hardened and restricted the flow into the screw below.


A dry clean and brush down of the internal area of the silo was carried out, cleaning the sidewalls and underside of the silo roof. Following the completion of the silo cleaning process, ACS Cleaning provided the client with a complete list of recommendations to help maintain the silo, which included organising an annual visit from our team to ensure regular inspections.

Silo Cleaning FAQs

Regardless of what the silo contains, there’s a number of methods the ACS Cleaning team can undertake. The most common and basic method is to simply brush down the silo’s interior manually, with the aim to scrape off debris while taking care to not scratch the silo surface. 

Vacuum Extraction Method

When it comes to cleaning food silos, our specialist cleaners recommend using the vacuum extraction method.  This is designed to take up as little of your business’ productivity time as possible as well as keeping you fully compliant with UK food safety and hygiene standards.

Bin Whip Method

For the toughest of jobs, experts at ACS Cleaning rely on the gyro whip cleaning method since it’s the safest and most efficient way of cleaning silos. The innovative gyro whip cleaning system combines the power of air blasting with the flexibility of hydraulic whip machines, meaning this silo cleaning method completely eliminates the risk of contamination and lost storage capacity. The gyro whip is designed to be the best method to tackle common storage silo issues such as rat holing and bridging.

Alternative Silo Cleaning Methods

ACS Cleaning avoids silo cleaning methods such as Vibrators and Low friction linings as these options are too expensive and can potentially damage the structure of silos.

This is the compaction of contents onto the side side of a silo. Rat holing not only reduces overall operating volume in silos, but also compromises on quality control, as the older, ‘rat holed’ contents begins to degrade and can potentially spoil the rest of the silo’s contents. The ACS Cleaning team uses the latest industrial cleaning equipment designed to eliminate rat holing issues in silos.

Similar to rat holing, bridging involves the compaction of materials at the bottom of the silo, with the potential to block the silo outlet – getting its namesake for the bridge-like shape that forms above the outlet. In order to avoid problems such as bridging occurring, it’s important that a regular silo maintenance schedule is carried out.

There’s a number of dangers concerning the usage and maintenance of silos. The most obvious risk present from the nature of working at height, as falls can occur from improper conduct or faulty equipment.

Dangers of Silo Loading

The loading process itself comes with a number of risks that operators face, since they need to work amongst the powerful conveyors and spinning PTO shafts as they monitor the flow of material, adjust speeds and turning the machinery on and off.

The preparation process for loading silos presents serious potential for risk as workers have to work directly below suspended, heavy unloader machinery.

Dangers of Silo Unloading

Meanwhile the unloading process bears unique challenges for operators to safely overcome. The fermentation of particular Silage can produce methane within the silo, which can lead to the asphyxiation of workers within the silo.

Lastly, silo operators with the responsibility of ‘walk it down’ during unloading face the risk of grain entrapment, as pockets in the silo material can give way underfoot which leads to the worker becoming stuck or completely sunk into the silo’s material in a sudden motion. This can lead to suffocation.


The National Agricultural Safety Database have set out a clear course of action for dealing with grain bin entrapment.

However, the most important thing to remember in the event that someone becomes entrapped in a silo’s contents is to immediately contact emergency services and follow their instructions. Taking this course of action will help avoid further accidents and improve the chances of a successful rescue.
