Entecon’s Automatic Sack Openers (ASO’s)

are a tried and tested bulk solids infeed system. Designed to be an industrial heavy-duty solution, they automatically open, empty and dispose of sacks or bales in high-throughput production environments.

The ASO range currently comprises two options: the original Automatic Sack Opening (the ASO) machine and a larger Bale Opener (ASO-Bale).

Entecon’s ASO’s are used in food manufacturing, chemical processing, plastics and the minerals industries, where health and safety, reduction of manual handling and overall efficiency gains are critical.

A Modern Bulk Solids Handling Solution –

“rip and tip” stations or sack opening machines only solve one problem: to open bags, Entecon’s ASO’s are an entire infeed system for bulk solids material processing:

01

Improve Health and Safety - Achieve Dust-Free, GMP-Compliant Operation

Fully enclosed design with integrated dust extraction protects your operators, your product and your environment.

02

Eliminate Manual Handling

Operators are no longer required to lift, cut and manually empty heavy sacks or bales.

03

Rapid and Versatile

The ASO opens and empties bags 10…80kg in weight with a max size 1200mm, 620mm and 250mm as quickly as 300 pieces / hr

04

Rapid and Versatile

The ASO-Bale opens and empties Bales with a maximum size of 950mm, 550mm, 270mm and a weight of 30Kg as quickly as 200 pieces / hr.

05

Engineered for Demanding Industrial Environments

Continuous, reliable and repeatable for heavy-duty industrial use made from Stainless Steel 304 or 316L. Unlike manual stations, automated systems deliver consistent sack processing rates regardless of operator fatigue or shift changes.

Frequently Asked Questions

What is an Automatic Sack Opener (ASO)?

What is an Automatic Sack Opener (ASO)?

An automatic sack opener is an industrial machine designed to slit open bags or sacks and safely empty bulk materials. Also known as a sack opening machine or industrial bag slitting system, it reduces manual handling and improves efficiency in industries such as powder handling, food processing, and chemicals.

How does an Automatic Sack Opening machine work?

How does an Automatic Sack Opening machine work?

The ASO uses precision blades to cut open sacks along the front and side edges while leaving the back edge intact. The material is then discharged onto a conveyor and moved into a product hopper for further processing. This type of bag slitting and discharge machine ensures consistent, high-speed operation with minimal manual intervention.

What industries use sack opening and emptying machines?

What industries use sack opening and emptying machines?

Sack opening and emptying machines are widely used in food processing (tea, coffee, milk powder, sugar, flour), chemical, and bulk material handling industries. Bale opening systems are typically used for fibres and compressed solid materials, while sack openers handle powdered and granular products.

What is the difference between an ASO-300 and an ASO-Bale opener?

What is the difference between an ASO-300 and an ASO-Bale opener?

The ASO-300 is designed as an automatic sack opener for Bulk Solids Handling; powders, granules, seeds and grains. Examples include salt, flour and fumed silica. An ASO-Bale opener is used for handling compressed fibre bales and solid materials, making it suitable for different industrial applications.

Can sack openers handle explosible powdered materials safely?

Can sack openers handle explosible powdered materials safely?

Yes, our ASO-300 is specifically designed for safe powder handling. It is supplied in 304 stainless steel as standard, with an option for 316L stainless steel for enhanced corrosion resistance. ATEX-compliant versions are available (Zone 22 external, Zone 21 internal), making it ideal for hazardous materials.

What is a dust-controlled sack opener?

What is a dust-controlled sack opener?

A dust-controlled sack opener is an enclosed system designed to minimise the release of dust during the opening process. Our machines feature a fully enclosed design and can be integrated with on-site dust extraction systems or supplied with dedicated extraction units, ensuring safe and hygienic operation.

Can the ASO be integrated with a check sieve and magnet?

Can the ASO be integrated with a check sieve and magnet?

Yes, to ensure that no bag material can enter the product stream we can integrate a sieve with magnet beneath the outlet of the product hopper. We can also connect to any type of valve or onward conveying system such as the Entecon Aero Mechanical Conveyor (AMC).

Is it possible to see an ASO in action?

Is it possible to see an ASO in action?

Yes, we have a number of installations in the UK and Europe where a visit is possible to see the machine in action.
