Mixers for Food and Beverage A Tasty Solution for Mixing Problems in Food and Beverage

Author / Editor: First published in PROCESS India / Dominik Stephan

Production machines for ready-made sauces, dips and mayonnaise are required to finely and thoroughly, yet gently, mix and emulsify components, while also ensuring uniform quality and economic operation. Since the requirements are very high, the machinery used should be efficient enough to fulfill them. Against this backdrop, IKA has developed the new SPP production system, which completes all steps without the use of any additional devices.

For the connoisseurs in the food processing industry, the expectations from ready-made sauces, dips and mayonnaise are clear: they must be appetizing on the plate and delicate on the tongue every time. Production machines play an instrumental role in meeting these requirements. When it comes to production machines for sauces, creams, etc., the new SPP production system from IKA stands out from the rest.

Fine emulsions and suspensions are the main application areas of this compact system; it provides high mixing performance with low space requirements. As a complete system, it combines containers, bypass pipe, valves, agitators and a control unit. Neither pumps nor any other equipment are needed to start production.

Setting a New Benchmark in Mixing Performance

One unique characteristic of this system is the low overall height: 135 cm for the smallest of the eight sizes and 426 cm for the largest. The advantages are obvious: easy handling and no costs involved for conversions. The system owes its huge homogenizing capacity to the combination of two agitators. A two-arm oblique blade agitator rotates in the conical container. A bypass pipe ensures the circulation of contents. The blade of the bottom agitator, which is mounted on the inlet of the installed dispersing machine, protrudes into the conical section of the container and ensures a high degree of turbulence there.

Even at reduced volumes and high viscosities, this additional agitator supports the homogenizing process and ensures optimum and thorough mixing. In combination with the two-arm anchor agitator driven from above, with leaf elements and fixed baffles, the result is optimum and thorough mixing of the contents in the container.

Separated Zones for Delicate Products

At the heart of the system is the direct batch inline (DBI) pump (shown in figure 1) and inline dispersing machine installed in the container outlet. This configuration means that the pump and dispersing zone remain separate from one another – indispensable for different process steps in the manufacture of several products.

The first stage of the DBI is designed as a pure pump phase. It allows recirculating product to be processed through the bypass pipe with no shearing. The first DBI stage can also be used as a product discharge pump. Its use as a cleaning in place (CIP) pump is also possible. This saves on the need for an additional CIP pump. The second stage of the DBI serves as a dispersing stage. A refined rotor/stator combination develops high shearing forces and guarantees very fine droplets and particle sizes – the most important requirement for long-term stability of emulsions and suspensions.
