Product Description

Diary milk cream separator Disc Stack Centrifuge with High G Force Low Consumption

Diary Milk Cream Separator, as the name suggests, is a device used to 'separate' cream from whole milk, dividing the whole milk into Skim Milk and Cream.Cream and skim milk have dissimilar densities, and therefore under the impact of gravity, they tend to get separated.

How Does a Centrifugal Milk Cream Separator Function?

The use of centrifugal force in a cream separator machine amplifies the separation of the milk. One centrifugal milk separation unit contains conical disks spinning in a bowl or drum at the speed of around 6,000 to 10000 revolutions per minute, depending on the structure and operating theory of separation.

A centrifugal force equivalent to thousands of times the normal gravitational force is created on the whole milk which is moving through the conical disks. Fat globules being the lighter part of the milk move to the heart of the drum, while the heavier skim milk moves to the outer sides as they get separated from the fat component. This is the process of cream-skimming.

About Reyes:Reyes Separator has been at the forefront in the field of disc stack centrifugal separation technology for more than 50 years - which is why disc stack centrifuges from REYES Separator perform this crucial separation function exceptionally well.

Today, REYES Separator is the leader in mechanical separating technology in China. REYES developments are used in a wide range of areas - in the beverage and dairy industries, in recovering and processing oils and fats, as well as in chemicals, pharmaceuticals, biotechnology and starch technology. Other applications include marine engineering, energy, oil fields and industry.

Centrifuge machine Standard design

The machine consists of a frame that has a horizontal drive shaft with clutch and brake, worm gear , lubricating oil bath and vertical bowl spindle in the lower part.

The bowl is mounted on top of the spindle in the lower part. The bowl is mounted on top of the spindle , inside the space formed by the upper parts of the frame , the ring solid cover, the collecting cover, and frame hood . The feed and liquid discharge system , including the paring disc pump for the heavy phase, also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solid-ejecting disc type with hydraulic operating system. The electric motor is of the variable frequency drive type or of controlled-torque type.

Basic equipment

Concentrator or purifier parts, inlet and outlet devices, revolution counter, set of erosion-protective parts ,illuminated sight glass box for light phase outlet , vibration switch , vibration-isolating base plate , flange motor, set of tool and standard set of spare.

Optional extras

Special Considerations That Influence Milk Separation

• Milk temperature:

  The optimal temperature required for milk separation is around 45º C.

• Several volumes of milk fat:

  More quantity of milk fat implies more quantity of cream after separation.

• Price of the milk:

  The small and medium capacity is of the solids (dirt, foreign particles) retaining separators, as against the larger capacity continuous operation self-cleaning Separators, Hence for the solids retaining separators, the separators need to stop after every few hours, the separator production is stopped so that separator bowl along with the disc stacks is washed to remove dirt, foreign particles, soil, slime and other external matter collected in the bowl that has been removed from the milk and clarified. The exact time needed for continuous separation changes depending on the initial quality of the milk being separated and how it has been handled at the farm level.

• REYES's Recommendation:

  As dairy plant machinery manufacturers, for small and medium capacity lines having solids bowl separators we recommend the use of two separators if continuous uninterrupted operation is needed. Then, you can ensure continuous processing of the milk and its centrifugation without interruption. The second separator can get to work when you clean the first one.
  
  Application :

Dairy separator: skim milk or clarify milk (out of solid impurities). Small separation machine is hand-driven, artificial
discharge, suitable for pastoral herdsmen's home use ; large separators for industrial production, electric drive, automatic or artifical discharge.
Mineral oil separator: for fuel oil, diesel oil, lubricating oil and transformers oil etc similar emulsion,remove mechanical
impurities and water.
Vegetable oil separator: for vegetable oil refining.
Animal oil separator: for refining animal fat in meat processing, or for fish oil concentration and separation processing.
Yeast separator: for concentrated yeast, nozzle discharge.
Starch separator: for removing protein in the starch and concentrating starch, nozzle discharge.
Lanolin separator:in wool industry for extracting lanolin,nozzle discharge.
Pharmaceutical disc separator: for the extraction of antibiotics, vitamins in the pharmaceutical industry;also for separating
liquid-solid three-phase mixture in the pharmaceutical and chemical industry.
Beer separator: for beer, malt juice and other beverages clarification.
Latex separator: for concentrating rubber latex and out of impurities.
Paint separator: for separating impurities in the coating, to improve the quality of the coating.

 

Operating principles

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe (1),and is accelerated in the distributor(2),which was specially designed to ensure smooth acceleration of the feed liquid(4). Leaving the distributor, the feed enters the disc stack(3). The separation into liquid-liquid-solid takes place between the discs, with the oil phase moving through the disc stack to the centre. When it reaches the centre, it is discharged through hole (5) and ejected into the collecting frame. The water and heavy solid separated from the oil move to the periphery, and the water flows via channels in the top disc(6) to the paring chamber, where it is pumped out of the rotor by means of a built-in paring disc(7).During purification, hot water is fed into the inlet of the bowl before the process liquid is introduced. The water forms a seal around the outer edge of the top disc. The solid collect in the periphery where they are discharged intermittently via the centrifuge cyclone. The solid are discharged by means of a hydraulic system, which forces the sliding bowl bottom(8)to drop down at preset suitable intervals, thus opening the solid ports at the bowl periphery

How it works

the disc centrifuge separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency. Inserting special plates (the "disc stack") provides additional surface settling area, which contributes to speeding up the separation process dramatically. It is the particular configuration, shape and design of these plates that make it possible for a disc stack centrifuge to undertake the continuous separation of a wide range of different solids from either one or two liquids. The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved in the specific application.
