Equipment for mixing various components

Purpose:

Equipment (food mixers) for mixing bulk, liquid and viscous components, incl. h. vacuum, mixers for moving dry bulk food products are divided into rotating and transporting.
Rotary mixers include drum mixers of various types, conical mixers, rotary pot mixers, etc.
Conveying mixers for dry bulk products include belt, paddle and screw mixers, V – obazny, such as “drunken barrel”, plow-shaped. The working bodies of transport mixers can be screws, including belt screws, or blades mounted on a shaft.

Drum mixers

The mixed material moves along the inner surface of the drum. When moving inside the drum, the material meets on its way the blades fixed inside the mixer hopper, rising to a certain height, the product is poured from top to bottom. Thus, an intensive circulation of bulk material is created inside the drum, which contributes to its rapid and thorough mixing. The mixture is unloaded through the loading hatch of the drum.

Homogenizers are designed for homogenization (grinding, mixing, emulsification, uniform distribution of components throughout the volume) of easy-flowing, as well as viscous and thick emulsions, in order to obtain highly dispersed and stable multicomponent compositions from difficult-to-mix liquids. Homogenizers can be in t. h. and multi-stage in horizontal or vertical design, separately installed and submersible.

Submersible mixers.

The advantage of a submersible homogenizer is the absence of mechanical seals, binding pipelines, which allows them to be used at higher temperatures, in aggressive environments, to place the homogenizer in containers of different volumes, the use of one homogenizer for several containers, alternately.

 Vacuum mixer-homogenizers  – a vacuum reactor with a stirrer, to which a homogenizer is connected for recirculation. After loading the main components into the reactor vessel, air is pumped out of the system, and the installation is switched on to the recirculation mode, during which the loaded components are crushed and mixed. The funnel which is built in system allows to load additional necessary components in the course of homogenization (under vacuum).

Ribbon mixers – Mixing is carried out by ribbon spirals, which not only mix, but also move the mixed material. In continuous mixers, the blades are fixed on the shaft along a helical line, which ensures simultaneous mixing and movement of the product along the shaft. Mixers can be either single or double or more, as well as equidirectional.

Paddle mixers – These are mixers with the highest level of mixing uniformity t . To . Equal-
speed movement of the mixing body is used with a close fit of the edges of the mixing blades to
the walls of the mixer, in contrast to horizontal and vertical screw mixers. The design of the
blades can be selected at the request of the customer.

Plow mixers – The most effective type of mixers, in which the working body is plow-shaped blades mounted on a shaft. They are used in technologies requiring additional grinding of components. These mixers consume more energy and create significant air currents, which
require the use of additional peripheral equipment to prevent product loss through gaps. However, such mixers can be operated at different filling levels and the mixing process takes a very short time.

Screw mixers – can be batch or continuous. The working body is a screw. The main advantage is the gentle movement of the product without disturbing the integrity of the structure of the pieces. Conveyors of this design are characterized by sufficiently high performance. The product is loaded through the feed opening , is picked up by the auger blades and mixed to the discharge opening . The movement can be made both horizontally and at an angle to the surface.

The conical vertical screw mixer – is a single-walled conical hermetic tank with a double screw mixer. The screw agitator consists of a small internal screw and a large external screw having the form of a cone-shaped spiral. The agitator rests on a removable, through the flange, bearing support with stuffing box packing. Unloading occurs through a sliding gate valve with a manual drive through a gearbox.

Centrifugal mixers –  The mixed material moves along the inner surface of the mixer cone from below along the radial generatrix under the action of centrifugal forces of inertia. When moving inside the cone, the material encounters on its way the blades fixed inside the mixer hopper. Thus, an intensive circulation of bulk material is created inside the mixer, contributing to its rapid and thorough mixing.

V-type mixer for powder products – V-type powder mixer, 100% mixing powder product, high efficiency feature, made of stainless steel. Product loading can be done manually or by vacuum suction.
