Definitions
- the invention relates to a separator for the sterilization of raw milk or whey according to the preamble of claim 1 and a method for operating a derar ⁇ term separator.
- separators for a wide variety of applications and power spectra.
- the separators must i.allg. be adapted to these applications and power spectra with regard to their construction and design. Although they can thus be used within the predefined task field or process, they respond to deviations from the given framework - thus being sensitive to changes in performance or changes in the composition of the products to be processed, or in many cases interfering with them.
- a sufficiently large liquid stream transports bacteria into a centrifugal field.
- recirculation of a Schlepfp damkeit is known from the prior art.
- this Schlepp supplementkeit which is recirculated into the inlet of the separator, bacteriologically corresponds approximately to the raw milk and is directed back directly into the inlet of the separator.
- the recirculated amount is based on the feed amount in some 3 - 5%.
- the Amount of Schlepfp Riverkeit is adjustable and should not have more than twice the germ number of the raw milk.
- the actual spore and bacteria concentrate are discharged via a solids discharge.
- the invention solves this object with regard to the separator by the subject matter of claim 1 and with respect to the method by the subject matter of claim 7.
- the invention provides a separator with two recirculation circuits between the two outlets and the inlet of the separator drum.
- the one recirculation circuit for recirculating a Schlepp gall ⁇ speed in the sterilization of milk is designed and has a recirculation line from the expiration of the centrifuge for Schlepflpcountrykeit to feed the centrifuge and the other of the recirculation is for recirculation of a part of the ent-germinated milk phase in the sterilization designed by milk and has a further recirculation line from the expiry of the centrifuge for sterilized milk to the inlet of the centrifuge, wherein in the recirculation circuits and lines preferably a respective controllable and / or controllable valve is integrated.
- a control or regulating device is additionally provided for keeping the product quantity processed by the separator constant by regulating the recirculation circuits.
- the invention it is possible, in particular, to supplement the advantageous circulation circuit for sludge fluid known per se by a further recirculation line or recirculation circuit for clarified (in particular sterilized) whey, with which the clarified whey is returned to the inlet.
- a further recirculation line or recirculation circuit for clarified (in particular sterilized) whey with which the clarified whey is returned to the inlet.
- the feed rate can thus be reduced in a degassing separator, or a type of "double sterilization" can be carried out for smaller machines, with the second recirculation line being activatable for keeping the feed volume of whey stable This ensures that the pressure range that has once been set is not left out.
- the grippers or peeling discs always demand the optimum range due to the same feed ratios due to the liquid flowing through twice
- the drum achieves stable and improved sterilization of less than 50 spores per liter even at low power.
- the invention also provides a method for operating a clarifier according to the invention, in which control of the product quantity processed by the separator is effected by means of a control or regulating device by controlling or regulating the amount of recirculated product phase into the inlet of the septa irrespective of variations in the supply quantity of milk product under hydraulically constant conditions (same flow conditions in the drum), wherein by means of a recirculation of clarified milk derived from the separator drum with optional return of a sludge liquid the separator in the Area of optimal sewage treatment is operated.
- DE 198 07 294 discloses a skimming station with a clarifier and a skimming separator arranged downstream thereof, a skimmed-milk recirculation line leading from the outlet skimming separator to the sewage separator inlet (a bypass line) in order to minimize the loss of grease and To improve the quality of the won cheese dust.
- DE 198 20 870 proposes, in the whey skimming by means of a separator, a partial amount of 0.5% to 2% of the expiring Molkerahmes - ie the portion containing more fat - fed back into the separator supplied raw whey to improve the product quality.
- FIG. 1 is a schematic representation of a plant for the sterilization of milk. and FIG. 2 shows a separator suitable for use in the method according to the invention.
- FIG. 1 shows a separator 1 to which a starting product-in particular raw milk-is fed by a feed line 2 directly or via a valve 9, a tank 3 and / or an advantageous heat exchanger 4 for increasing or keeping the temperature constant (with arrows indicated on the heat exchanger, the flow of sauer ⁇ liquid).
- the raw milk is heated here by way of example to a temperature of 55 ° C.
- the separator 1 of FIG. 1 serves as a sterilization separator or is designed as such. Such a separator with a vertical axis of rotation is shown in FIG.
- the raw milk is supplied through the supply line of FIG. 1, which opens into the supply pipe 10 leading into the drum 12, which is followed by a distributor 11, through which the raw milk is fed into the centrifugal space in the drum 12 with a separator plate insert 13 ,
- the degerming separator 1 clarifies the raw milk of germs and / or other contaminants which are discharged via solids discharge openings 14, for example by means of a piston slide closing mechanism 15, out of the drum 12 of the separator 1.
- the sterilized milk is discharged from the degerming separator 1, for example, via a first gripper or a peeling disk 16 and a first outlet 17 downstream of it and a first outlet line 5 connected downstream of it.
- the discharge line 6 is designed as a recirculation line which opens into the inlet 2 of the separator drum.
- the first discharge line 5 for the sterilized milk also has a branch line 21, which opens or is designed as a further recirculation line into the product feed 2 of the separator 1.
- a branch line 21 which opens or is designed as a further recirculation line into the product feed 2 of the separator 1.
- controllable valves 7, 8 are integrated into the recirculation conduits in order to be able to control or regulate the amount of recirculated sludge fluid and / or recirculated germinated milk.
- the raw milk to be processed has, for example, about 4.5% lactose, 3.5% fat and 3.5% protein.
- the sludge usually has a markedly reduced fat content and an increased egg white content compared with the raw milk to be processed.
