Abstract
Description
Išradimas gali būti panaudotas pieno pramonės srityje. Šiuo metu gaminant koncentruotą liesą pieną naudojama vakuuminiai-išgarinimo procesai.The invention can be used in the dairy industry. Vacuum-evaporation processes are currently used to produce concentrated skim milk.
Tokie gamybos būdai aprašyti Rusijos Federacijos patentuose Nr. RU 2048113, SU 1496031, RU 2052938 ir kituose. Jų trūkumai yra tie, kad minėtuose patentuose naudojami procesai neigiamai veikia baltymus ir laktozę, esančius liesame piene. Žinomais būdais gaminant koncentruotą liesą pieną veikiant temperatūroms gamybos procese nukenčia baltymą laktozės struktūrą tai apriboja produkto tolimesnį panaudojimą.Such methods of production are described in Patents Nos. RU 2048113, SU 1496031, RU 2052938 and others. Their disadvantages are that the processes used in the said patents adversely affect the proteins and lactose present in skim milk. Known methods of producing concentrated skimmed milk under temperature conditions in the manufacturing process suffer from a protein structure of lactose, which limits further use of the product.
Taip pat žinomas būdas aprašytas Rusijos Federacijos patente Nr. SU 1837412. Šiuo būdų gaminant sutirštinama iki 24 % sausųjų medžiagų.A known method is also described in the Russian Federation patent no. SU 1837412. In this process, up to 24% of dry matter is thickened.
Išradimo tikslas yra pagaminti natūralų liesą koncentruotą pieną 35-37 % sausųjų medžiagą kuriame nepakistų baltymų laktozės struktūra.The object of the invention is to produce a natural lean concentrated milk 35-37% dry matter which does not change the lactose structure of the protein.
Tikslas pasiekiamas naudojant visame gamybos procese žemas temperatūras ir koncentruojant liesą pieną membraninės atvirkštinės osmozės-nanofiltracijos būdu.The goal is achieved by using low temperatures throughout the production process and concentrating lean milk by membrane reverse osmosis-nanofiltration.
Siūlomas lieso pieno membraninio koncentravimo žemoje temperatūroje gamybos būdas, kai atšaldytas pienas vėliau pašildomas, toliau separatoriuje atskiriami liesas pienas ir riebalai. Nauja jame yra tai, kad liesas pienas pasterizuojamas plokšteliniame pasterizatoriuje - šaldytuve - 56-57,8 °C temperatūroje, išlaikant 25-90 sekundes, po to atšaldomas iki 15-20 °C temperatūros ir nukreipiamas į tarpinę balansinę talpą iš kurios paduodamas į membranines RO/NF-reversinės osmozės-nanofiltracijos filtrą kur gaunamas lieso pieno koncentratas 35-37 % sausųjų medžiagų.A method of producing membrane concentration of low-fat skimmed milk is proposed, whereby the chilled milk is subsequently heated, further separating the skim milk and fat into a separator. What's new is that the skimmed milk is pasteurized in a plate pasteurizer - refrigerator - at 56-57,8 ° C for 25-90 seconds, then cooled to 15-20 ° C and fed to an intermediate balancing container from which it is fed to the membrane RO / NF-Reverse Osmosis-Nanofiltration Filter where 35-37% of dry matter is obtained as skimmed milk concentrate.
Siūlomą lieso pieno koncentravimo gamybos įrenginį sudaro RO/NF-reversines osmozėsnanofiltracijos filtravimo blokas, susidedantis iš keraminės membranos, galinčios atskirti molekules ir jonus, kurių dydis mažesnis negu 0,0005-0,01 ųm, membranų paviršiaus plotas yra 4300-4700 m2, o slėgis 60-70 barų arba du membranų blokai, kiekvienas poThe proposed skim milk concentration production unit consists of an RO / NF-reverse osmosis filtration filtration unit consisting of a ceramic membrane capable of separating molecules and ions less than 0.0005-0.01 µm in size from 4300 to 4700 m 2 , o Pressure of 60-70 bar or two membrane blocks, each after
2150 -2350 m2, slėgis 30-35 barai, darbinė temperatūra 12-25° C.2150 -2350 m 2 , pressure 30-35 bar, operating temperature 12-25 ° C.
Išradimas paaiškinamas lieso pieno membraninio koncentravimo žemoje temperatūroje principine schema.The invention is illustrated by the principle scheme of membrane concentration of skim milk at low temperature.
Į gamybą pristatytas karvių pienas iš pienovežio 1 priėmimo vamzdynu yra nukreipiamas į plokštelinį šilumokaitį-šaldytuvą 2, kuriame yra atšaldomas iki 4-8 °C temperatūros. Atšaldytas pienas sukaupiamas ir saugojamas tolimesniam perdirbimui tarpinėje talpojeCow's milk delivered to production from the milk truck 1 is routed via a receiving line to a plate heat exchanger-refrigerator 2 where it is cooled to 4-8 ° C. Chilled milk is stored and stored for further processing in an intermediate container
3. Iš tarpinės talpos 3 pienas per plokštelinį šilumokaitį 4, kuriame pašildytas iki 36 °C temperatūros, nukreipiamas į pieno riebalų atskirtuvą-separatorių 5, kuriame atskiriamas liesas pienas ir riebalai. Separavimo metu gauti riebalai nukreipiami į grietinėlės talpą 11 tolimesniam perdirbimui, o liesas pienas nukreipiamas į plokštelinį šilumokaitįpasterizatorių-šaldytuvą 6, kur pasterizuojamas 56-57,8 °C temperatūroje su išlaikymu iki 90 sekundžių ir kuriame atšaldomas iki 20 °C temperatūros, ir nukreipiamas į membraninės filtracijos atvirkštinės osmosės-nanofiltracijos bloką 8, kur sukoncentruojamas iki 35-37 % sausųjų medžiagų ne didesnėje kaip 20-21 °C temperatūroje. Sukoncentruotas liesas pienas nukreipiamas į plokštelinį šilumokaitį 9, kuriame atšaldomas iki 4-6 °C temperatūros ir nukreipiamas į koncentruoto lieso pieno talpą 10.3. From the intermediate container 3, the milk is directed through a plate heat exchanger 4, heated to 36 ° C, to a milk fat separator 5, where the skim milk and fat are separated. The fat obtained during separation is diverted to a cream container 11 for further processing, and the skim milk is diverted to a plate heat exchanger-pasteurizer-refrigerator 6 where it is pasteurized at 56-57,8 ° C with a holding time of 90 seconds and cooled to 20 ° C. membrane filtration reverse osmosis-nanofiltration unit 8, where up to 35-37% of dry solids are concentrated at temperatures not exceeding 20-21 ° C. The concentrated skim milk is diverted to a plate heat exchanger 9 where it is cooled to 4-6 ° C and directed to a concentrated skim milk container 10.
Šis produktas gali būti toliau naudojamas pieno pramonėje, gaminant didelio tirpstamumo lieso pieno miltus su sąlyga, kad bus išdžiovinti purkštukinėje džiovykloje žemoje temperatūroje, taip pat visuose pieno produktuose, kur gamyboje reikalingas natūralus liesas pienas.This product may continue to be used in the dairy industry for the production of high-soluble skimmed-milk powder, provided that it is dried in a spray-jet at low temperature, as well as in all dairy products requiring natural skimmed milk.
