Butter oil concentrator

Butter oil concentrator

In the production of butter oil, the cream concentration
stage is followed by the phase inversion process. Then
the emulsion and the heavy phase (serum phase) are
separated from the product by an oil concentrator, which
increases the oil concentration to up to 99.5%. The reduction
in free fatty acids (FFA) is obtained by washing the oil with
water that is separated from it again together with the
undesired FFA in an oil polishing separator. A vacuum dryer
further reduces the moisture in the fi nal product to >99.8%.

Nozzle separator

Nozzle separator

The right equipment for soft cheese and yoghurt.

The FRAUTECH nozzle SEPARATOR for the dairy industry is designed for dairy applications to increase performance and profitability through excellence in solid/liquid separation. Our state-of-the-art nozzle separators are the most reliable and efficient solution for separating Greek yoghurt, quark, or soft cheese from the whey and concentrating them.

The CNZ 601 model is offered for a capacity of 8,000 l/h total flow input and 2,000 l/h total output of cheese/yoghurt.

OPERATING PRINCIPLES

• The continuous separation process starts when the product is introduced gently into the bowl through the feed pipe and the distributor in order to reduce shear stress on the product.
• The solids are subjected to centrifugal force and forced towards the periphery of the bowl, accumulating in the area that holds the solids.
• The concentrated cheese/yoghurt is discharged automatically and continuously through the nozzles.
• The clarifi ed product rises through the disc stack up to the centripetal pump that discharges it through an enclosed pipe.

Cream separators

Cream separators

Cream separation, either from milk or whey, is a key process in the dairy industry.

In cream separation from milk, either full or partial skimming can be applied, whereas in whey processing, only full skimming is applied to recover the valuable fat that remains in the whey after cheese production.

Gentle treatment of the milk to avoid damaging the fat globules is an essential requirement that FRAUTECH SEPARATORS can guarantee thanks to the optimized design in feeding the separator. When full skimming is required, high skimming efficiency is a must, and our are designed to ensure this. Under optimal feeding and process conditions, the residual fat in skimmed milk is always at the lowest possible level, i.e. 0.05% or less. Milk fat standardization with FRAUTECH cream separators is made possible thanks to the built-in standardizing apparatus that allows fat re-mixing into the skimmed milk for manual adjustment.

OPERATING PRINCIPLES

• The whole milk or whey is fed under pressure through an enclosed pipe.
• It then fl ows smoothly into the bowl through the feed pipe and the distributor and starts rising through the rising channels.
• Due to the centrifugal force and the milk’s higher specifi c weight, it is forced towards the periphery of the bowl while the cream is concentrated in the central area.
• Both skimmed milk and cream rise along their respective paths and are pumped out or leave the separator, respectively, through enclosed pipes.
• The solids are also subjected to the action of the centrifugal force and are pushed to the periphery of the bowl, accumulating in the area that holds the solids, and automatically discharged at preset

Bacteria removal clarifiers

Bacteria removal clarifiers

Bacteria removal from milk and whey significantly improves the quality of final products.

For instance, in production processes where the milk
temperature does not exceed 50 °C throughout the
entire process – production of raw-milk cheese for
example – a higher product quality is obtained by using
a bacteria removal separator. Undesirable effects often
caused by bacteria, such as acid fermentation and
cheese blowing, are thus avoided.

Furthermore, a reduced shelf life of soft cheese and soft
cheese-based products may also be attributed to the
presence of bacteria. As in the previous case, bacteria
removal greatly contributes to achieving a longer life of
fresh milk and a better quality of whey-derived products,
such as protein drinks.

Used with warm milk/whey – ideally at
55-62 °C – for maximum separation efficiency, they
guarantee the highest bacteria removal rate

OPERATING PRINCIPLES
• The milk/whey is fed under pressure through an enclosed pipe.
• It then fl ows smoothly into the bowl through the feed pipe and the distributor.
• The bacteria and other solids subject to the action of the centrifugal force are forced towards the periphery of the bowl and accumulate in the solids acceleration zone before being automatically discharged at
pre-set intervals.
• The clarifi ed milk/whey rises through the disc stack and up the centripetal pump that discharges it through enclosed piping.
• The concentrate rises above the upper disc to reach the centripetal pump.
• The concentrate can either be discharged or recirculated into the bowl to further concentrate the bacteria for discharge

Clarifiers: The craft beer clarifier

Clarifiers

Milk clarifi cation is a very important step in milk processing when aiming for high-quality dairy products. The purpose of milk clarifi cation is to improve the milk quality by removing solid impurities such as dirt, straw, and sand particles, somatic cells, and bacteria.

The effective separation of solid impurities is strictly linked to the viscosity of the milk: the lower the viscosity, the higher the separation effect. Hence, for clarification purposes, warm milk is preferred to cold milk and a clarification temperature of approximately 50 °C may be considered as the optimum temperature to achieve maximum efficiency. Nonetheless, especially in those areas where the raw milk quality is questionable, milk clarification can also be performed with cold milk as soon as it arrives at the dairy. In whey processing, the clarifier allows removal of the cheese fines prior to whey skimming. This leads to increased efficiency in cream separation, resulting in higher fat recovery with low and consistent residual fat content in the skimmed whey. A low residual fat content helps to optimize operation of the membrane filtration unit or evaporator that follows

OPERATING PRINCIPLES
• The milk/whey is fed under pressure through an enclosed pipe.
• It then fl ows smoothly into the bowl through the feed pipe and the distributor.
• Thanks to the action of the centrifugal force, the solids are forced towards the periphery
of the bowl and accumulate in the solids acceleration zone.
• The clarifi ed milk/whey rises through the disc stack up to the centripetal pump that discharges it through an enclosed pipe.
• The accumulated solids are automatically discharged at pre-set intervals
