Universal vacuum module for making milk-based ice cream mixtures 100

The vacuum module for the production of liquid milk mixtures is specifically designed for medium and small-scale production facilities and fast/street food companies, allowing for the rapid and efficient dissolution of powder mixtures within the working liquid, dispersing and homogenizing them, resulting in a stable emulsion. If necessary, it can also cool or pasteurize, by supplying the installation's jacket with a thermal heat transfer agent for heating/cooling (optional).

This mixer for the production of milk-based mixtures for ice cream is suitable for both “cold” and hot technological processing methods.

Advantages:

• A special type of a multi-stage disc homogenizer for highly efficient dissolution and mixing, which does not require an additional pump thanks to its strong self-priming function.
• No dead zones during stirring, mixing, homogenization due to the special shape of the stirrer and the bottom valve. The bottom valve also minimizes possible product losses during unloading and maintains a high hygienic standard during sanitation.
• The vacuum system for the basic version includes a special Venturi pump operating on compressed air; at the customer’s request, a contact vacuum gauge can be installed to maintain and adjust the vacuum depth (optional).
• Fluoroplastic scrapers are already included in the basic version; they help clean the walls and bottom of the installation; suspended scrapers guarantee maximum pressure applied on the walls and bottom of the working reactor. The scrapers have a high durability, good ductility, and low friction coefficient! They hold certificates for use in the food industry.
• An inclined version of the installation with gravitational mixing of the product, which is 50-60% more efficient than the classic mixing method.
• A small-volume “jacket” for the coolant (up to 0.5 Bar), installed along the entire height of the working tank, including the bottom, which at the same time boasts a large heat transfer area, while exhibiting low “inertia” when switching from cooling to heating and back. This significantly reduces energy losses when replacing the coolant (heating/cooling) depending on the required technological process.
• Professional bottom temperature sensor made out of stainless steel (PT100) with a food-grade certificate for direct contact with the product. This sensor enables precise temperature control of the mixture, allowing for regulation through a temperature controller and the use of a coolant from an external source (optional).
• The module is capable of complete self-cleaning with the installation of CIP heads for washing (optional).
• The installation allows for the vacuuming of working mixtures.

Basic version

It consists of a 3-layer inclined vacuum reactor on a supporting structure, equipped with a jacket for the coolant from an external source, a mixing device with a reinforced electric drive, an external circulation circuit with a multi-stage homogenizer with two operation circuits, backup connections for CIP heads for sanitation, a bottom DN40 valve, and a vacuum generation system. A three-way valve allows for changing the operation mode of the installation from homogenization to cleaning and maintanance. The control system incorporates a soft start for the homogenizer and the mixing device.

The vacuum generator requires a source of compressed air with a pressure of 6-10 bar.

Options:

• Thermal insulation. Depending on the temperature conditions of processing, a low-temperature insulation option can be selected, or a high-temperature type of thermal insulation - made out of mineral wool.
• Wheel swivel supports, resistant to loads and physical wear, with a brake mechanism and a special coating for food production.
• CIP heads (nozzles) for washing are made out of food-grade stainless steel; as an additional option, rotary nozzles can be ordered so that you could cover all surfaces of the container, including the opening hatch of the equipment.
• Vacuum loading through a special pipe with a hose for vacuum filling the container through the bottom valve up to the level of the working fluid.
• A special low-speed air compressor with a working pressure of 6-10 Bar.
• Professional flow-through stainless steel filter with a quick-change cartridge for cleaning.
• Circulation pump (if the filter option selected).
• Electrical cabinet made out of carbon steel with IP54 protective coating containing signal, safety, and control electrical components (relays, contacts, etc.).
• Single-phase control design.
• Sources of hot/cold coolant (water heating systems and ice water stations).
