A whey separation machine primarily separates whey from curd after milking cows or goats. The machine uses different separation principles to isolate whey, which contains lactose and protein, for processing into various products. There are four main types of whey separation machines.
Centrifuges
The whey separation machine centrifuge is a common whey separation device. The machine uses centrifugal separation theory to separate the curd and whey. After adding the mixed liquid into the centrifuge container, the motor will begin revolving at high velocity. The high centrifugal force will push the liquid mixture to the container wall. This will separate the particles based on density. Heavy particles such as cheese and casein will settle on the container wall, while lighter particles, such as whey, will remain on the liquid surface. The whey will be extracted separately. Whey separation machine centrifuges are suitable for large-scale production because of their efficiency and quick processing speed.
Cozzator separators
This type of whey separation machine is named after the Italian word for "mixers." The device works by first mixing the milk and introducing it into a bowl. The mixing and whirling propel the milk's fat particles to the bowl wall. The whey is then drained from the outlet. Cozzator separators are ideal for separating skim milk and whole milk. Unlike centrifuges, Cozzator separators drain whey immediately after the first cycle. Therefore, the machines can continue operating for a long time without stopping.
Membrane filtration systems
Membrane filtration systems are whey separation machines based on molecular sizes and weights. The whey protein, minerals, and lactose are smaller than larger particles such as fats and casein. Because of this size difference, the machine can pump the milk through a semipermeable membrane. Only whey, which includes the smaller molecules, passes through the membrane. Casein, fat, and other larger particles remain on the other side of the membrane. Membrane filtration systems offer the advantage of selective fractionation. The device can produce whey protein concentrate and isolates, depending on the membrane used.
Flow rate:
The flow rate is the amount of fluid processed by the machine per unit of time, usually expressed in liters per hour (L/h) or kilograms per hour (kg/h). The typical flow rate of whey separation machines is as follows:
- laboratory-scale machines: 100 to 1,000 liters per hour
- pilot-scale machines: 1,000 to 10,000 liters per hour
- industrial-scale machines: 10,000 liters per hour or more
Operating pressure:
The operating pressure of whey separation machines is usually between 0.5 and 2.0 megapascals (MPa), which is the pressure at which whey and other components are separated during the separation process.
Separation efficiency:
Separation efficiency is the ability of the whey separator machine to separate whey proteins, fat, and other components, usually expressed as a percentage. The separation efficiency of whey separation machines is between 90% and 99%.
Power:
The power of whey separation machines can be divided into driving power and separate power. The driving power is that of the motor driving the machine, and it is usually between 5 and 20 kilowatts (kW). The separation power refers to the power required for the separation process, which is usually between 3 and 10 kW.
Overall size and weight:
The overall size and weight of the whey separation machines with different capacities and designs are different. The following is an approximate value:
- overall size: the height is about 2-4 meters, the width is about 1-2 meters, and the length is about 1-2 meters.
- weight: between 500-3000kg.
Clean:
It is very important to clean the whey separation machine regularly. This will help remove residue, bacteria, and dirt, keeping the machine hygienic and safe. Users can choose suitable cleaning agents and disinfectants according to the separation machine's materials and processing products. The cleaning agents should be safe and effective. During cleaning, users need to ensure that all parts of the machine are thoroughly cleaned and rinsed, avoiding residues that may contaminate subsequent processed foods. Users should develop a regular cleaning schedule and ensure the necessary equipment and materials for cleaning. This is particularly important in food processing applications.
Physical examination:
Whey separation machines need to undergo regular inspections and maintenance to ensure their normal operation and performance. Users should develop inspection and maintenance schedules according to the manufacturer's recommendations and guidelines. Regular checks should include fluid level checks, to ensure the fluid levels in the separation chamber are within the appropriate range to avoid dry-running or over-fill situations.
Users should also inspect the gaskets and seals for damage or wear, as gaskets and seals are critical to the separation chamber's leak-tightness and need to be replaced if they are damaged or worn.
In addition, users should inspect and clean the filters and strains to ensure that the separating efficiency of the whey separation machine is at an optimal level. This will ensure that the machine can separate components.
If problems are found during inspection, such repairs or replacements are required to avoid further damage or affecting the performance of the separation machine.
The primary application of the industrial whey separation machine is in the food and dairy processing industries. Dairy plants utilize whey separators to extract high-quality whey protein concentrate from whey permeate, which is a byproduct of cheese production. The concentrates have high protein content, making them desirable for use in protein-rich food products, nutritional supplements, sports nutrition products, and food fortifications. Additionally, whey separators are utilized to remove excess lactose from whey to produce lactate products and to process whole milk, skim milk, buttermilk, and yogurt whey for the extraction of valuable dairy components. Beyond dairy processing, the food and beverage industry employs whey separators to extract specific functional proteins from dairy ingredients that can be added to gluten-free products, fat and oil products, bakery products, emulsifiers, and clarifying agents in juices and beverages. Meat processing companies also use whey separators to extract proteins and phosphates that can be utilized for meat product bonding, enhancing the quality, texture, and shelf life of sausages, processed meats, and meat products. By doing this, the separators help improve food yield and reduce waste in the industry.
