Everyone understands the importance of correct weighing and continuous or batch dosing. And how this must include correct registration of volume and weight. Dinnissen can provide excellent assistance in this area, with both gravimetric and volumetric solutions. Your Dinnissen contact person will be happy to hear about your requirements and wishes.
With a batch production process of a few tons per hour, Dinnissen can provide you with a dosing and weighing system that is accurate to a few grams. This means in practice that during a process cycle, a micro-component can be accurately weighed and dosed to within 2 grams. These results have been validated in various sectors, including baby food, pet food and detergents.
During batch weighing, the weight of one or more raw materials is measured in a weighing hopper. For example, by adding raw materials to the weighing hopper (dosing) or by removing raw materials from the weighing hopper (extracting a dose). With batch weighing, the weight of the desired quantity of raw materials is set in advance. The dosing in or out of the raw materials is done roughly in the first phase of the dosing process (bulk dosing). In the final phase, dosing in or out is handled slowly and in small quantities (fine dosing). Dinnissen has developed a self-learning control system to handle this dosing process optimally and adjust it automatically if and when necessary. In short, the dosing process can be adjusted to current product conditions, and thus control the correct dosing speed and increase the dosing accuracy.
Dinnissen has the capability to offer highly accurate weighing and dosing in continuous processes. This means in practice that, for example, up to 1 kilogram of micro-component (vitamins or probiotics) can be dosed in a process with a main flow of 1 ton per hour. These results have been validated in various sectors, including baby food, pet food and detergents.
With continuous weighing, the flow of a raw material from a weighing hopper through a dosing system is measured in relation to a unit of time (i.e. loss-in-weight). Firstly, the infeed of this raw material from the weighing hopper is measured in relation to a unit of time by a weighing module and calculated in combination with a special weighing and dosing control system (Setpoint). In this way the weighing and dosing control system determines the final dosing capacity (the amount of raw material that flows out of the weighing hopper per unit of time) and also ensures that the weighing hopper is refilled in time. And that means your production process can continue running continuously, which makes continuous weighing extremely suitable for processes such as furnaces, extruders and mixers that must run constantly.

The Dinnissen Feeder Valve is an easy-to-clean dosing technology with an enormous capacity range.
The production capacity of the innovative dosing valve can be adjusted effortlessly from a few kilograms to tens of tons per hour. This makes the Feeder Valve ideal for situations in which a wide range of products are dosed with one dosing element. The Feeder Valve is simply constructed with just one drive. The dosing valve’s compact installation height makes it easy to install in a new or existing setup. The compact and simple construction minimizes product residue and facilitates quick and easy cleaning. The Feeder Valve hardly uses any energy, and it can be used in many sectors. It combines high production capacity with a high level of dosing accuracy, which eliminates the need for smaller dosing and weighing systems. The Feeder Valve has been validated by leading producers of milk powder, cocoa powder, creamers, sugars, whey powders, lactose, premixes and baby food.

There is a wide variety of raw materials and liquids that can conceivably be added to the production process during mixing or coating.
Consider, for example, essential oils and fats, acids, aromas, enzymes and vitamins. The quantity of liquid to be dosed can vary from a few grams to hundreds of kilos per batch.
During this process, the viscosity, solidification temperature and acidity of the materials subject the equipment to high demands. Dinnissen has the right knowledge to develop systems for raw and liquid materials that meet all the requirements of modern dosing systems. Weighing systems, flow measurement and mass flow measurement are used for batch and continuous dosing, depending on the application and desired accuracy. Frequency-controlled pumps ensure that the desired liquid dosing runs at the correct speed. Depending on the application, our liquid dosing systems are built into heated and insulated housings or constructed as skids. Good accessibility for inspection and maintenance is always essential here.
