Batch means discontinuous, the simplified production sequence as follows:
- venting spigot must always be open to vent air in a filter, preferably slightly under pressure;
- filling through the product inlet, with the unloading door closed;
- mixing, with unloading door closed, product inlet closed or open only if connected with a closed feeding hopper; emptying of the mixed product through the unloading door.
The machine is categorised as an open system; the production sequence consists in a flow of product that enters from the loading inlet, then it is mixed, and exits from the unloading outlet. Both inlet and outlet doors are always open. Therefore, it is important to remember that the final product quality depends on the permanence inside the mixing chamber and on the volume of product in the processing phase.
Mode of operation
Powerful mixer’s mixing tool rotates as mixing elements in special arrangement on the mixer shaft in a horizontal, cylindrical drum. The size, number and positioning, geometric shape and peripheral speed of the mixing elements are coordinated in such a way that they produce a three-dimensional movement of the components. The resultant turbulence in the mix, whereby all the product is constantly involved in the mixing process, prevents the formation of deadspots or low-movement zones in the mixing drum and ensures high speed, precision mixing. To prevent particles from being squashed against the drum wall, the mixing elements are specially shaped to lift product from the wall within the radial movement of the mix.
Are composed by two symmetrical plough-shaped faces. The space between the two faces is closed with a specially shaped metal sheet to prevent the wedging of the product. This tool works on the principle of mechanical fluidisation (centrifugal whirling of the products) obtains excellent mixing quality in a very short time.
Mix Paddles require a longer mixing time than ploughshare, but are easier to clean, paddles are normally used with pastes and moist or sticky products.
The fourfold screw ribbon is used for non intensive and gentle mixing or to keep the product agitated to avoid lumps. It is used also to homogenise different batches obtained with ploughshare or paddle intensive mixers in a single batch.
