Description
Technical field
The utility model relates to field of biotechnology, in particular to a kind of bioconversion for immobilized lactase reacts
Device.
Background technique
Milk is high-protein nutrient substance, particularly important for infant, and the immune of infant can be improved in long-term drinking
Power promotes the growth of infant.But various products quality problems continuously emerge in dairy husbandry at present, from melamine to various
Hormone is mixed into the health for all having seriously endangered baby.Other than these harmful substances, newborn system is constrained there are one factor
The absorption of product nutrition --- lactose intolerance.According to Thesis Statistics, 80% or more Asians has lactose intolerance, only some
The amount that people drinks is few, without manifest symptom.In order to most of people can suck up milk nutritional ingredient, must just develop low
Lactose milk.
Nowadays domestic Dairy Processing preparation field is also increasingly developed, and the demand of fresh milk is increasing, but is till now
Only domestic big city can buy fresh milk, and single remote small city can't buy, and can only buy the milk of high temperature sterilization taken care of for a long time.
This is also required to the improvement and exploitation of fresh milk production technology, the especially production technology of Low lactose milk fresh milk will be wait improve and open
Hair.There are many methods for industrial production Low lactose milk plain chocolate technique at present, but integrate, and can arrange as following two work
Skill:
Technique one (fresh milk):
Net cream → the pasteurize of raw milk → centrifugation → cooling and enzyme hydrolysis lactose → detection terminal → sterile filling；
After this method is using Pasteur's antivirus, the bacterium or bacterium bud that fraction is harmless or beneficial, more heat-resisting are still remained
Spore, thus pasteurized milk will 4 DEG C or so at a temperature of save, and the holding time is short, a problem is also that circulation
In the process, there is also therefore the mouthfeel of milk can also become the activity of lactase, and the currency is long, can sweeten.
Technique two (high temperature sterilization milk):
Net cream → the ultra-high temperature sterilization of raw milk → centrifugation → cooling and sterile addition lactase → sterile filling → is transporting
And it is digested in sales process；
This method uses ultra-high temperature sterilization, so operates the resting period for substantially increasing milk, but 135 DEG C are arrived
150 DEG C of flash pasteurization processing, although the microorganism that can wherein grow and gemma can be destroyed completely, high temperature can make
Some thermo-labile nutritional ingredients of milk are destroyed, lactose therein also can coking, protein and lactose also occur that one
Fixed Maillard reaction makes milk brown stain, and destroys the original flavor of milk.Addition lactase sterile for enterprise itself and nothing
The filling operating cost that can increase enterprise significantly of bacterium is unfavorable for enterprise's profit.For consumers, this low-lactose milk exists
It is digested in transport and sales process, will increase the changeability of product, it is just suitable for the possibility mouthfeel first drunk, with
The mouthfeel of the extension product of resting period can increasingly sweet tea, a possibility that consumer buys again is small.
All there is a problem of that a bit common for above two process, enzyme does not all extract after usage,
In this way for drinking the enzyme that can be taken in the enzyme of some inactivations for this or not be inactivated, and cream is decomposed for enterprise itself
The expense of lactase required for sugar is also a no small spending.
Summary of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of bioconversions for immobilized lactase
Reactor.Using the bioconversion reactor as reaction vessel, low-lactose milk is prepared using immobilized lactase, has been digested
At the rear recycling for realizing immobilized lactase.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bioconversion reactor for immobilized lactase, including reactor tank body, blender and fixing groove, institute
State be provided on the top cover of reactor tank body feed inlet, discharge port and condensation interface tube, the blender be located at reactor tank
Engine connection above body, is provided with agitating paddle on blender, and the fixing groove is located at the bottom of reactor tank body, and described
Reactor tank body is detachably connected, wherein equipped with magnet or electromagnet for recycling immobilized lactase.
Further, the condenser pipe is U-shaped condenser pipe.
Further, air hole is provided on the top cover of the reactor tank body.
Further, dismountable by the way of cutting ferrule, screw thread or flange between the fixing groove and reactor tank body
Connection.
Further, the bioconversion reactor is using heatproof (resistance to 270 DEG C), transparent PC material (such as poly- carbon
Acid ester resin) it material is made is made.
Bioconversion reactor described in the utility model for immobilized lactase, beneficial effect compared with prior art
Fruit are as follows:
The bioconversion reactor for immobilized lactase is arranged dismountable fixed in reactor lower end
Slot can be used for recycling the immobilized lactase with magnetic material wherein being assembled with magnet or electromagnet, prepare Low lactose milk ox
When milk, lactase is removed.The immobilized lactase of recycling can recycle after processing, not only greatly reduce Dairy Enterprise production
The cost of low-lactose milk, moreover it is possible to which the mouthfeel for guaranteeing product by real time monitoring Degree of Enzymatic Hydrolysis improves product quality.
The utility model is described in further detail with reference to the accompanying drawings and examples.
