Simplified mayonnaise production -
continuously
In recent years consumption of mayonnaise and salad dressings has increased globally: Bran + Luebbe has been an active supplier in this area of food processing for many years
As any good chef will tell you, making mayonnaise and salad dressing is one of the more challenging of culinary operations When it comes to making these products on a commercial basis, the process can be equally as demanding - requiring the highest levels of performance from mixing, blending and pumping equipment in order for the finished product to exhibit perfect consistency

Where a company is seeking to manufacture both mayonnaise and salad dressing from the same production line, then the most economical approach is to employ continuous processing.
In recent years consumption of mayonnaise and salad dressings has increased globally, with manufacturers examining new approaches to increasing production whilst still maintaining a quality product.
Bran + Luebbe, an SPX Process Equipment company, has been active in this area of food processing for many years and is always prepared to bring new ideas to the table.

Its latest development has been to respond to a request from a leading mayonnaise manufacturer in Europe for system capable of producing 10 t/hr, with the capability to offer different flow rates, colloid mills, CIP cleaning and simple changeover from mayonnaise to salad dressing production.
"If you want to increase production volume without taking up additional valuable floor space, then a continuous processing unit is a very realistic proposition," comments B+L Systems Manager Mike Scott.
"Switching from batch to continuous processing reduces both cost and waste.
The system that we have now designed eliminates complex valve and pipe arrangements along with the large process tanks".
The four sets of ingredients, these being liquid egg yolks, liquid premix spice/vinegar, oil and starch are delivered into header tanks from which they are proportioned and pumped using a Bran + Luebbe multi-head H4 pump.
The levels of the ingredients within the suction tanks are controlled by level indicators and automatic valves.
This arrangement will send a signal to stop the proportioning pump should there be a loss of ingredient.
The liquid pre-mix tank is equipped with a Lightnin ECL mixer to keep the ingredients in suspended state.
Each of the ingredients is delivered by H4 pump to a single manifold from where they pass through a homogenising valve and into a pre-emulsifier tank.
The resulting pre-emulsion is pulled out from the tank using Waukesha cherry-Burrell Universal II pump and on through to a colloid mill before finally entering the filler.
The employment of the WCB Universal II pump ensures that the pre-emulsion is subject to low shear forces and a gentle action to avoid damage to the product.
The pre-emulsifier tank contains a bottom entry fixed speed agitator and is also fitted with a low level transducer, which controls the speed of the pullout pump to maintain a standard volume within the tank even with variances in demand from the filler.
Bran + Luebbe has given consideration to the hygienic aspects of the process, so all components comply with the relevant international sanitary regulations and are fitted equipped with fittings that allow CIP cleaning.
All the mechanical elements of the system, pumps, tanks, mixer, pre-emulsifier tank, colloid mill, drive unit and control panel are contained on a single skid, thereby enabling simple installation and easy maintenance.
"The system is designed to provide a constant and even flow of product through to the filling line at all times," says Mike Scott.
"We appreciate that with this type of food product, ensuring that the raw ingredients are proportioned in accordance with the recipe and then once converted into a pre-emulsion held in a constant state through to the colloid mill.
For these reasons, we are employing proven pumping and mixing technologies that provide the highest levels of accuracy and processing repeatability.".
