Description
Technical field
The utility model relates to food processing field, particularly relates to a kind of equipment for sterilization of milk sterilization.
Background technology
Milk is indispensable nutritional necessary product in people's daily life, but usually containing more germ, directly can not drink, need to carry out sterilizing process in fresh milk.
(1) bacterium
The microorganism existed in cow's milk has bacterium, yeast and mould, and it is most important for wherein preserving with the meaning in processing with bacterium at cow's milk.Bacterium size is on average about 1/125 of cow's milk fat globule, and O.6um diameter is about.
1, lactic acid bacteria
Lactic acid bacteria can utilize carbohydrate to produce lactic acid, namely carries out lactic fermentation.From cow's milk, be easy to separation obtain lactic acid bacteria, it belongs to lactic acid Cordycepps on taxology.Lactic acid bacteria is generally without spore coccus or bacillus, belongs to anaerobic type or amphimicrobian type bacterium.When carrying out lactic fermentation, it produces volatile acid or gas sometimes.
2, bacterium acidi propionici
Lactose and other carbohydrate breakdown, for producing the flora of propionic fermentation, can be propionic acid, acetic acid and carbon dioxide by this.This kind of bacterium is gram-positive short, for manufacturing the leavening of Swiss Cheese, porose on its cheese made.
3, enterobacteria
Enterobacteria parasitizes in intestines, is Gram-negative brevibacterium.Enterobacteria is amphimicrobion, with coliform, pathogen, salmonella for flora.
Coliform by carbohydrate fermentation, can produce acid and the gas such as carbon dioxide, hydrogen.Because coliform comes from ight soil, so be defined as the Bacteria Indicators of cow's milk pollution.
4, spore-bearing bacillus
Spore-bearing bacillus, for forming endosporous Gram-positive bacillus, can be divided into aerobic bacillus and anaerobic Clostridium.
5, Mycosphaerella
Mycosphaerella is aerobic chromatogenous gram-positive cocci.In cow's milk, normal appearance has Mycosphaerella and staphylococcus.Staphylococcic thalline arranges as grape cluster, and it mostly is the reason bacterium of Bovine Mastitis Milk or food poisoning.
6, pseudomonad
Pseudomonad is the aerobism bacterium utilizing flagellum movement, and Pseudomonas fluorescens and pseudomonas putrefaciens represent bacterium for it.Lactoprotein can be resolved into peptone or butter oil decomposition is produced lipolysis smelly by this bacterium.This bacterium can growth and breeding at low temperatures.
7, alcaligenes
Bacillus alcaligenes can make organic salt (citrate) contained in cow's milk decompose and form carbonate, thus makes cow's milk change alkalescence into.Bacillus foecalis alkaligenes is Gram-negative aerobism bacterium, and this bacterium exists in people and animal intestinal, and it makes cow's milk pollute along with ight soil.The suitable growth temperature of this bacterium is at 25-37 DEG C.Ropy milk Bacillus alcaligenes is everlasting in water and is existed, and being Gram-negative bacteria, is aerobism.The suitable growth temperature of this bacterium is at 10-26 DEG C, and its decapacitation is produced outside alkali, and can make cow's milk cement.
8, pathogen
Sometimes be mixed with pathogen in cow's milk, meeting communicate illness in crowd, therefore strictly must control sterilization, the sterilizing of cow's milk, pathogen is not existed.
The main pathogenic fungi be mixed in cow's milk has: the salmonella typhi of Salmonella, salmonella paratyphi, intestines class salmonella, the Shigella shigae of Shigella, the comma bacillus of vibrio, Bacterium diphtheriae, humanoid tulase, ox shape tulase, Bang's disease brucella, anthrax-bacilus, coliform, staphylococcus, hemolytic streptococcus, Streptococcusagalactiae, pathogenicity clostridium botulinum.
(2) fungi
Yeast in fresh milk is mainly the Pseudomonas such as saccharomyces, pichia genus, Torulopsis, candida, common are Saccharomyces fragilis bacterium, Hong Shi torulopsis, Caucasia koumiss torulopsis, torulopsis etc.Wherein, Saccharomyces fragilis and Candida can make lactose fermentation and in order to manufacture fermented dairy product.But the dairy products using yeast to make are often smelly with yeast, have the defect on local flavor.
Mould common in cow's milk has that milk powder born of the same parents are mould, mould, the black beads of cheese powder born of the same parents is mould, variation beads is mould, cladosporium herbarum, penicillium casei, Penicillum glaucum, Aspergillus glaucus and aspergillus niger, penicillium casei wherein can cheese-making, and it is corrupt that remaining most of mould can make cheese, cheese etc. pollute.
(3) mattress body is bitten
The filterable virus of infringement bacterium is referred to as bacteriophage, is also called bacterial virus.Find the bacteriophage of most bacteriums such as Escherichia coli, lactic acid bacteria, dysentery characterized by blood in the stool bacterium, Salmonella, cholera bacteria, staphylococcus, tulase, actinomyces at present.Bacteriophage length mostly is 50-80nm, can be divided into head and afterbody.Bacteriophage head contains DNA (DNA), can arrange inhereditary material, makes it have selection specificity to host strain; Afterbody is made up of protein.Bacteriophage first adheres to host bacteria, and then invades this thalline internal breeding, when after the most new phage of its ripe generation, releases, and produce bacteriolysis by new phage.
For the microorganism of cow's milk, dairy products, most important bacteriophage is lactic bacteriophages.Lactic acid bacteria as cheese or yogurt bacterial classification has and is occurred by the situation of its phage attacks, so that causes the loss in Dairy Processing.
Bacterium with regard to above a multitude of names needs the means process of employing science, otherwise will form great life threat to people.
Generally adopt high-temperature sterilization mode to the sterilization of milk, sterilizing, when cooling to the drinkable temperature of people after high-temperature sterilization, people just can directly drink.But the nutritional labeling of milk after sterilizing is often ignored by people, because milk only just can kill all bacteriums under high temperature 130 degree of states, and milk just loses nutrition after temperature reaches 100 degree, and this is the general knowledge of ordinary person's the unknown.For solving this contradiction, people take the methods such as cryogenic freezing, all fail thorough solution both to have ensured that milk nutrition was constant, reach again the problem of thorough sterilizing.How founding one can effective kill bacteria fungi, can ensure again the new equipment for sterilization of milk sterilization that milk nutritional labeling does not run off, and belongs to current important research and development problem in fact.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of equipment for sterilization of milk sterilization, make it effectively can kill bacterial fungus in milk, can ensure that again milk nutritional labeling does not run off, thus solve the deficiency that existing sterilization of milk sterilization can destroy milk nutritional labeling.
The utility model provides a kind of equipment for sterilization of milk sterilization, comprise apparatus body, filter and heater, described apparatus body is provided with import and outlet, above apparatus body, filter is installed, filter is provided with heater, heater is connected with temperature control system, is provided with ultraviolet ray sterilizing device between described filter and import.
