AZO COMPONENTER® Step – automatic weighing of minor and micro components

Until now, minor and micro components had to be weighed manually, thus entailing risks and potential errors. These grow with the number of components and batches, and with the required weighing and metering accuracy. This has an adverse effect on product safety and quality overall.

 

Manual operations may under certain circumstances require a large number of staff and demands a high degree of concentration from them during weighing processes. They are to some extent exposed to relatively high amounts of dust. Occasionally automatic dosing units are also employed, which meter the ingredients onto a weigh belt feeder. However these require substantial outlay for cleaning; neither can they prevent cross-contamination.

 

In order to resolve the problems described above, AZO is expanding its already extensive portfolio for automation of minor and micro quantities with the AZO COMPONENTER® Step. This system makes it possible to weigh minor and micro components automatically with gram accuracy, such as flavourings, baking agents, emulsifiers, colourings and other ingredients. It improves product safety while simultaneously boosting production efficiency by reducing individual manual production steps to a minimum.

 

Especially when it comes to sectors with stringent requirements for hygiene, batch purity and product separation, the AZO COMPONENTER® Step enables adherence to the strict regulations and requirements of specific branches.

 

Fully automated filling and transport within the plant result in high throughput rates while achieving considerable levels of accuracy. Tracking and tracing of all raw materials used guarantee maximum product safety. All process steps and weighing results are reproducible, which ensures consistent, strict adherence to recipes. Strict separation of batches prevents cross-contamination, e.g. between allergens and non-allergens. What is more, the AZO COMPONENTER® Step is extremely flexible when it comes to changing products over thanks to its modular design.

 

The system was especially designed to satisfy the high requirements for hygiene in the food industry. This is primarily achieved by having the products filled into receptacles and keeping exposure to dust to a minimum by using aspiration. The outlay for cleaning can be kept low by using storage and target containers for the specific product groups. If necessary, target containers can be provided with liners.

 

The system comprises two levels. The components are held ready in surge bins on the upper level. Prior to filling, the raw materials can be identified using the barcode and allocated to the correct hoppers. This keeps mix-ups of products to a minimum and ensures that raw materials can be traced back. The surge bins can be filled from sacks or big bags; pneumatic filling is also feasible.

 

The target containers are processed sequentially on the lower level below the metering points using a hydraulic carriage. After dosing in the product quantity specified in the recipe, the target container is transported on to a dosing point.

 

There are separate scales provided for each component. Simultaneous weighing of components results in maximum time gain. Dosing screws combined with vibration bottoms underneath the surge bins ensure accurate metering of components being handled. A vibrating discharge chute can also be used for metering. Once all components are in the target container in accordance with the recipe, it is ejected at the end of the metering line and is ready for the next process.



The target containers are tracked using RFID technology and are thus monitored throughout the entire weighing and metering process. This means that the position, the weighed components and also the allocation of the target containers to a particular recipe are documented and are reproducible.

Product category: Volumetric dosing and metering equipment

AZODOS® product family - Continuous gravimetric dosing of powdered products

AZODOS® type P … DV dosing unit is used for volumetric metering of powdered products in weighing and finishing processes. The machine can be used in the food, pharmaceuticals, chemicals and plastics industries for feeding production processes with a constant mass flow in coarse or fine flow.
 
By adding a weighing device, the machine can be extended to form the AZODOS® type P... DW dosing system for gravimetric feeding of processes. The machine can be used as loss-in-weight scales to dose small quantities into the downstream system with gram accuracy. The AZODOS® P… DW is used with the AZO®CONT dosing controls for feeding continuous gravimetric processes, resulting in a DDW loss-in-weight feeder.

Design of AZODOS® types P … DV and DW
The basic machine consists of a housing where, depending on the model, one or two dosing screws are installed. The dosing screws are driven by frequency-controlled gear motors. An upstream discharge agitator serves to ensure that the dosing screws are evenly filled from surge bins. The surge bins are available in a variety of models and sizes and, depending on the model, can be filled under gravity, pneumatically or manually. An extraction device can be used to remove the dosing screws from the back of the housing, which makes cleaning or replacing individual components very simple.

If the basic machine is expanded with a platform load cell or a 3-point weighing frame, this forms an AZODOS® type P … DW dosing system that can be used as loss-in-weight scales. Flexible connections at the supply hopper inlet and screw outlet decouple the system thus preventing force shunts. If the AZODOS P….DW is combined with the AZO®CONT dosing controls, this creates a loss-in-weight feeder. The controls continuously regulate the mass flow in terms of target and actual throughput.
 
Operating principle of AZODOS® type P … DV, DW, DDW
The AZODOS® Type P … DV operates in volumetric mode. The powder bulk products flow out of the supply hopper into the dosing screw. An agitator is used to ensure uniform discharge. With a frequency-controlled motor, the dosing screw can be switched from coarse to fine flow for precision dosing in the downstream weighing process.


In the case of dosing scales, the basic machine is mounted on a platform load cell or integrated in a 3-point weighing frame. It can be mounted in a frame structure on the floor or suspended from the ceiling. The dosing screw meters the bulk material in coarse/fine flow to the downstream process. The amount of product that is metered out of the AZODOS® is weighed. The system operates gravimetrically in accordance with the negative weighing principle.


The AZODOS® type P … DW becomes a loss-in-weight feeder if an appropriate control system (e.g. AZO®CONT) is provided. The bulk material is discharged by the dosing screw and the resulting loss in weight per unit of time is registered by the weighing and control system. The actual loss in weight per unit of time (actual throughput) is compared against the required setpoint, which is defined by the downstream process, e.g. extruder. Differences between the actual decrease in weight and the decrease in target weight over time are corrected by adjustments to the batch controller's throughput.


Once the product reaches a predefined level in the AZODOS®, the control process is paused briefly and the surge bin is refilled. During the refill time the dosing screw output is set to a value based on empirical weight and output data gained from previous dosing cycles.
 
Operation and control
Up to 10 dosing stations can be controlled with the central AZO®CONT controller. The system is displayed and its parameters set on an operator control panel. A PC-based visualisation system (Intouch, WinCC, etc.) can be connected corresponding to requirements. An interface for the KASTOR process control system is additionally integrated in the controller. Extensive work flows such as balancing and recipe handling can be implemented with this process control system. The material feed for replenishing the dosing units can be additionally controlled with the AZO®CONT controller. AZO®CONT can control up to four independent collective feeding system with max. 32 receivers.
The most diverse requirements can now be configured with a single AZO®CONT control unit. This is regardless of whether this involves controlling up to 10 AZODOS® dosing units or whether up to an additional four collective feeding systems are to be controlled with a maximum of 32 receivers in total.
