Mechanical coater MC-500 is designed for:

  • coating of feed pellets, food snacks and similar products
  • application of fat, vitamin supplements
  • application of hydrolysates and other liquid flavor additives
  • application of dry aromatic additives

 

COATER’S CHALLENGE: Applying up to 15% of various additives to the product

 

Application: as part of technological lines

 

The principle of operation of a mechanical coater:
spraying liquid and dry additives on the surface of raw materials and kneading in a closed space.

At the same time, the processing of the product takes place in a gentle mode – without significant deformation.

ADVANTAGES

  • Dosing accuracy (flow meter): 0.5%
  • The supply of raw materials to the coater is regulated by the loading conveyor into the coater shaft.
  • The gap in the partitions of the shaft is adjustable in the range of 10 ... 30 mm.
  • Fluid inlet control - pressure valve
  • Adjustment of the input of dry additives - dispenser
  • The heating circuit is only filled with distilled water!

DESIGN DESCRIPTION:

 

 

 

  1. Heating and supply system of liquid impurities
  2. Mixer
  3. Mine
  4. Collector
  5. Control cabinet

 

The system for heating and supplying liquid impurities (1) is used to heat the raw material to a predetermined temperature and feed it to the collector (4).

A manifold (4) is installed on the mixer body, which serves to connect the heating system and supply liquid impurities to the shaft nozzles.

Shaft (3) is intended for applying heated impurities to raw materials using nozzles installed in its body.

A mixer (2) is installed on the frame of the system, in which the product is kneaded, on which liquid impurities have already been applied, and transported to the unloading zone.

 

IMPORTANT! The heating circuit is only filled with distilled water!

 

Through the fitting (11) the system is connected to a tank with pre-cleaned raw materials.

Further, the raw material is fed by a pump (9) to an indirect heating boiler (1).

A heat exchanger (17) is placed in the boiler, which heats the raw material to a predetermined temperature. The required level of raw materials in the boiler is maintained by means of float sensors (16).

The supply and return of the coolant to the heat exchanger occurs through the sleeves (2).

Heating of the heat carrier is carried out by means of an electric boiler (7), circulation by means of a pump (8).

Boiler safety group (5) – a set of devices combined into one housing, designed to protect closed heating systems operating under pressure. To compensate for the thermal expansion of the coolant in the system, it serves as an expansion tank (6).

A tap with a fitting is designed to fill the heating circuit with water.

The coarse filter (3) serves to prevent dirt from entering the circulation pump (8).

The heated fluid is supplied by a pump (10).

The flow rate in the heated liquid supply system is adjusted using a manual valve (14), an automatic valve (13) and a flow meter (15).

 

 

 

In the housing (3) there is a mixing screw (2) driven by a geared motor (1).

For quick access to the mixing screw, there is a cover (4) on top of the housing.

To unload the product from the mixer, a branch pipe (5) is used.

 

The supply of raw materials to the coater is regulated by the loading conveyor into the coater shaft.

 

 

In the upper part of the shaft there is a connecting flange (1) and partitions (2) (3). Partitions are adjustable. Adjustment is necessary to set the minimum layer of raw materials on which impurities are applied.

The gap in the partitions of the shaft is adjustable in the range of 10 … 30 mm.

In the shaft body (4) there are nozzles (5), a flange for supplying loose impurities and an inspection door (6).

In the lower part of the shaft there is a flange (7) for introducing the hydrolyzate.

QUALITY ASSURANCE

Warranty period is 1 year

• all machines are certified according to ISO 9001: 2015
• our coaters are designed for continuous and trouble-free operation

WARRANTY SUPPORT

SEQUENCE OF OPERATION

Liquid additives are fed into the system for the preparation of liquid impurities through the fitting, which are fed into the boiler by means of a pump. The filling of the boiler takes place automatically using the level sensors located in it.

The electric boiler is turned on, heating the coolant (water) in the system. With the help of a circulation pump, the coolant is supplied to the boiler heat exchanger, where the raw material is heated.

The heated additives are pumped to the collector and then to four pneumatic nozzles. Visual control of the pressure and temperature of the liquid in the collector is carried out using a thermomanometer.

The drive of the mixing screw is switched on and the raw material is fed into the intake pipe of the mine using a conveyor.

The raw material, passing through the shaft, enters the spray zone of liquid additives with nozzles and enters the mixer, where the product is kneaded.

The finished product leaves the mixer through the outlet pipe.
