Centrifugal sifter sifts bulk food products, removing impurities from them. The principle of operation of the sifter is based on the continuous centrifugal squeezing of bulk materials through cylindrical sieves of a predetermined flow section.


Technical parameters:
performance is up to 3.5 t / hour;
total power 1.5 kW;
supply voltage 380 V;
overall dimensions 540×980×430 mm;
weight 45 kg.

Feeding screw

Feeding screw loads the raw material into the extruder. From the hopper, located at a height of 0.5 – 0.7 m, screw transports raw materials to the height of filling products into the extruder.

performance of screw feeding is up to 500 kg / hour;
installed power is up to 1.5 kW.


Belt type mixer produces batch mixing of bulk food ingredients in order to prepare dry multicomponent mixtures of uniform polydisperse composition, suitable for further use in the food process.


Technical parameters:
performance is from 250 kg / hour;
working volume 250 liters;
installed power 2.5 kW;
supply voltage 380 V;
overall dimensions from1500×1600×1020 mm;
unloading height is up to 2.5 m;
weight 350 kg.

Extrusion unit

The extruder performs thermomechanical processing of the raw material, coming after the preparation stage. Design of the working bodies will allow you to get any form of the final product.


This is achieved by:

length of the working area is 0.65/0.9 m, which determines the quality of the welding of the extrudate and, as a result, high taste properties of the product. After passing the working area, the products do not require additional drying / roasting in thermal installations.
automatic control of parameters of the equipment, ensuring a stable output of the product when the quality of raw materials fluctuates.


Adjustable parameters include:
working area pressures;
extrusion temperature;
raw material humidity;
quantity of raw material.

Technical parameters:
performance is up to 500 liters / hour;
frequency of the auger rotation 10-280 rpm;
operating temperature control range 40 … 200 °C;
screw diameter 88 mm;
working pressure before the matrix 20 MPa;
installed power, up to 90 kW;
supply voltage 380 V, 50 Hz;
overall dimensions 4600×1600×3000 mm;
service life of working bodies, not less than 300 000 kg.

Cutting device

The roller type cutting device carries out rolling and cutting of a continuous semi- wet tube, tape or bundle of extruded food product. The device can also be manufactured for operation in rolling and clipping mode.


Technical parameters:
speed of rotation of the rolls, up to 200 revs / min;
width of the formed tape, up to 120 mm;
overall dimensions 1120×850×1150 mm;
 installed power, up to 1.5 kW;
supply voltage 380 V;
weight, not more 100 kg.

Thermal drying station technical parameters:

installed power 75 kW, 15 kW per level;
number of levels 5;
working width of the mesh 0.7 m;
working length of the mesh is 4.5 m (from roll center to another roll center);
working area of the one transportation mesh 3.15 m2;
working area of all conveyor meshes 15.75 m2 (without feed conveyor).

Dragee complex

Complex sprinkles pre-dosed powdered flavoring ingredients (salt or sugar) on the products. Application of dry components occurs simultaneously with the addition of liquid components.


Stable dosed content of ingredients in the product is ensured by the fact that:

single-screw doser carries out the dosage of additives with an accuracy of 2%, allowing you to fully comply with the recipe;
the doser produces a direct supply of additives, directly filling the components into the working area of the complex;
the sprayer evenly sprays liquid components throughout the entire volume of the coating complex;
in addition, the drum body has uneven edges, which 98% exclude the possibility of breaking the product.

Basic equipment of coating complex includes:

hopper with level sensor;
doser of dry components;
liquid component sprayer;
frequency converter for regulating the rpm of the drum;
complex control system.

Installed power is up to 4 kW;
Overall dimensions 1200×4000×2000 mm.

These functional features of the complex, constant monitoring of the content of components, thoughtful design provide ease of use and high taste, which will be appreciated by your customers!

Capacity of the extrusion line up to 400 kg / hour* in the production of croutons.

* depending on the raw material, used technology, quality of the product
