Vacuum mixer with a homogenizer VMG SL 300

The vacuum mixing unit provides the highest level of homogenization of the mixture and intensive mixing for a short time and with minimal energy consumption.

Carried out processes:

• Heating, cooling
• Cooking
• Mixing
• Dispersion
• Emulsification
• Homogenization
• Deaeration

Design

The plant’s design consists of a thermally insulated cylindrical vessel equipped with a heating jacket for a liquid heat-carrier or steam. Depending on the customer’s requirements, the working vessel’s design can be welded or fitted with a lifting or hinged lid. The unit is equipped with a frame agitator with a top or bottom drive and built into the bottom of the vessel’s homogenizer type rotor stator. The plant in its standard configuration is equipped with a vacuum station and an automatic control system based on PLC.

The product is intensively circulated through an integrated high performance homogenizer and mixed with a horizontal agitator, providing efficient heat transfer between the sides of the vessel and the product. The special shape of the agitator and the placement of the emulsifying homogenizer ensure efficient operation of the plant using only 15% of the total volume of the vessel. Installation of a one or two-level contour of the outer recirculation is possible.

A highly hygienic design of a vacuum emulsifying mixer is made in accordance with the requirements of GMP. 

Features and options

• Any degree of surface treatment.
• Standard configuration of the plant is designed to work under a vacuum; it is possible to manufacture the plant for operation at significant pressure.
• Any form of agitator on demand, variable speed mixer.
• Ability to install a multi-stage homogenizer to produce super thin emulsions and ointments.
• Possibility for installation of an external high speed homogenizer, which for certain applications may replace the use of a high pressure homogenizer. Feeding of ingredients with a flow meter or tensometric system.
• Device for sanitary sampling during the process.
• When inserting of powdered ingredients directly into the vacuum chamber, a homogenizer for complete wetting and uniform distribution of the particulates in the fluid.
• Fixed or rotary CIP balls.
• Interchangeable working elements of homogenizer allow picking the perfect type of rotor and stator for various applications.
• Advanced control system with visualization, temperature control, agitator speed, homogenizer speed, depth of the vacuum pressure.

Technical characteristics:

• Working volume 250 - 270 L
• Agitator drive 1.5 kW
• Length without cabinet 1280 mm.
• The homogenizer is three-shell, the heating is provided by a heat transfer medium, which is supplied from an external source (cooling also from an external source).
• The homogenizer is equipped with two temperature sensors (which are used to sense the temperature of the product and the heating liquid).
• Homogenization is provided by an inline homogenizer with an electric motor with an output of 7.5 kW.
• Mixing of the product is ensured by a paddle full-volume stirrer.
• The agitator is driven by a 1.5 kW motor with a frequency converter.
• The frame has adjustable legs.
• The vacuum homogenizer is equipped with both analog and digital vacuum gauges / pressure gauges (analog range is from -1 to 0 bar) digital (SMC PSE533-M5L) has a range of -101 - 101 kPa.
• The product outlet is secured through a DN 50 pipe.
• The vacuum unit serves for better efficiency due to the fact that it lowers the boiling point of the liquid, which requires less heat for heating and thus less power.
