HETHON - Feeder technology
Conventional solution: stirring arms and screws
Conventional solution: stirring arms and screws
Conventional solution: stirring arms and screws
The dry substances you work with, sometimes don’t have a natural flow.
The accurate dosing of these substances is therefore often a challenge.
In conventional machines screws and stirring arms are applied to dose the dry substances. The substance is in motion, but there is a risk of damage, segregation, ratholing, bridging and compacting of your dry material.
As a result the dosing is not accurate, material is lost and the continuous flow of your production process is at risk.
In addition, the many moving components and contact parts require extra maintenance, so there is a relatively large risk of damage.
The HETHON solution: Flexible Wall Hopper
Conventional solution: stirring arms and screws
Conventional solution: stirring arms and screws
Hethon dosing machines are equipped with a Flexible Wall Hopper:
a hopper with a flexible exterior of sustainable Polyurethane.
By externally, mechanically and evenly massaging the walls of the hopper, by use of paddles, the dry substances continuously keep in motion.
Thus the material is transported smoothly towards the dosing screw.
As the mechanical paddles are not inside the wall hopper, as opposed to the stirring arms and screws, the dry material will not get damaged and ratholing or bridging is prevented.
Therefore even poorly flowing and compacting raw materials are easily and accurately dosed.
It is also possible to have the screw and the paddles move quicker or more slowly, independently. This way one can fiddle with the proper settings.

How to prevent Bridging and ratholing
By externally massaging the hopper walls, by use of paddles, the dry substances continuously keep in motion and prevents Bridging and Ratholing.
HETHON Feeders with two drives are suited to dose bad flowing dry products accurately at various feed rates. When using the 1 drive type at slow speed (=low capacity) the agitation is proportionally decreased.
When using the 2 drive type with low capacity, the agitation drive can be adjusted at any required rate independently from the feed rate.
The hopper is easy detachable!

Applications
A Flexible Wall Hopper for every application
A Flexible Wall Hopper for every application
A Flexible Wall Hopper for every application
Our Feeders are used for the accurate dosing of many dry substances. For every application there is a Flexible Wall Hopper with the appropriate specifications.
The easily detachable dosing hoppers can, as an exchange hopper, be conveniently stored elsewhere. This saves cleaning costs, for instance in case of colour changes or pigments.
The white Hopper is the standard one.
FDA certified and ATEX application
A Flexible Wall Hopper for every application
A Flexible Wall Hopper for every application
HETHON has FDA certified hoppers for your food application to ensure all relevant parts meet the requirements of set rules.
For ATEX applications HETHON developed an Anti - static Hopper to put in an ATEX Feeder.
And as you can read below, there is also a hopper available that represents these applications in a hopper: FDA and ATEX approved in one.
Is your application not included? Feel free to enquire about the possibilities for your process!
Maintenance
A Flexible Wall Hopper for every application
High-quality construction and material
HETHON Feeders have a long lifespan and require little maintenance as a consequence of a minimum number of moving parts being subject to wear.
As all parts are easily detachable, our Feeders are very easy to clean. Our maintenance department is at your service to keep our products in production for many years. A lifetime over 23 years in heavenly conditions is no exception.
Moreover, your own maintenance department can easily carry out the work activities using the included manual or with the help of our specialists.
High-quality construction and material

High-quality construction and material
In order to achieve optimal stability our constructions are not made of sheet metal but from solid steel tube frames. These are manufactured from SUS 304 or SUS 316. The contact surfaces are made of Polyurethane, SUS 316 POM. These materials have an excellent chemical resistance and are suitable for virtually all foodstuffs and pharmaceutical applications. The frame is constructed so heavily that our dosing device can even be used as a support for a silo. The HETHON Feeder can also be installed as a dosing machine hanging underneath a silo.
FDA and ATEX
High-quality construction and material
FDA and ATEX
Are you looking for a hopper that is FDA and ATEX approved together in one hopper?
It took a long time, but it's here! We can supply you exclusively with this hopper. The material was approved in the laboratory, so that after a long wait we have now obtained the certificate.
Solutions for aggressive powders
Paprika powder
Paprika powder is a good example of an unexpected aggressive powder. We have good experiences and references for dosing this with our special hoppers!
And for example Lime. For this we also have very good, special made, solution!
HETHON - Makes your business flow
It’s all about the flow!
The flow in your business: that is what we, at HETHON , are here for! For decades our Feeders have applied a perfectly dosed flow of hard-to-dose materials.
Capacity overview
Available feeder models
