Description
Technical field
The present invention relates to biochemical field, particularly relate to the reactor producing immobilized enzyme, specifically refer to a kind of Preparation equipment and using method of particulate state immobilized enzyme.
Background technology
Modern biotechnology achieves the scale operation of enzyme, and free enzyme is widely applied in food, chemical industry and medicine industry.Although enzyme can catalyzed reaction efficiently under normal temperature and pressure conditions, and has very high specificity, enzyme as a kind of protein, poor stability, all unstable to heat, strong acid, highly basic and organic solvent etc.
[36]even if, under the optimum reaction conditions of enzyme, also often very fast inactivation.And free enzyme can only adopt batch reactor, after reaction, enzyme can not reclaim, and makes product separation purification difficult, easily causes protein contamination, so be not also a kind of desirable catalyzer concerning free enzyme modern industry.For this reason, people have prepared all kinds of immobilized enzyme.In all kinds of immobilization material, carrageenin, gelatin have good stability, advantage that cost is low, are consumption immobilization materials the most widely.But the glue after immobilization is generally large bulk, need manual or machinery section, and sheet catalyst loads and unloads into reactor inconvenience, laminar flow is poor, easy fluid short circuit etc. in reactor, and section too increases operation and causes the loss of catalyzer.
Spherical catalyst has advantage widely, can carrageeenen immobilized enzyme be changed into spherical by general sheet? have researchist to do some to attempt.Illustrate based on water incompatible with many organic solvents if any document, water is dispersed into the principle of drop in organic solvent, (Sun Wanru, microbiology is circulated a notice of, 1986,13 (1): 213-35) report uses butylacetate dispersion carrageenin liquid, forms spheroidal particle.Concrete grammar is as follows: the carrageenan solutions adding hot preparation 8%, 60 DEG C are cooled under room temperature, the enchylema getting 20ml glue and 20ml40% mixes, stream is added in the butylacetate of insulation 30 DEG C of stirring, until be dispersed into small-particle, add the KCl solution of 10%, continue stirring 10 minutes elimination solvents, then the KCl adding 2% solidifies the immobilized cell that namely a hour form 1 ~ 3mm.The shortcoming of this method is that the butylacetate used not easily reclaims, and solvent has people irritant, needs to operate under the environment that security is higher.
But also there is no at present industrial can cheaply on a large scale preparation with the Apparatus and method for of gelatin, particulate state immobilized enzyme that carrageenin is material or immobilized cell generally.
Summary of the invention
The object of the invention is the shortcoming overcoming above-mentioned prior art, provide a kind of Preparation equipment and the using method that can prepare particulate state immobilized enzyme on a large scale.
To achieve these goals, the present invention has following formation:
The Preparation equipment of this particulate state immobilized enzyme, its principal feature is, the Preparation equipment of described particulate state immobilized enzyme comprises step-down gear, whipping appts, heating jacket, cylindrical shell and shower nozzle, described step-down gear is connected with above described cylindrical shell, whipping appts is provided with in described cylindrical shell, be provided with heating jacket outside described cylindrical shell, be connected with shower nozzle below described cylindrical shell, wherein said shower nozzle is Conic nozzle.
Preferably, described whipping appts is paddle paddle.
More preferably, described heating jacket is built-in with heating medium, and described heating medium is water and steam, and Heating temperature is 20 ~ 120 DEG C.
Further preferably, described Conic nozzle is distributed with circular hole or the aciculiform shower nozzle of 0.5 ~ 2mm, and described Conic nozzle aperture is 0.8 ~ 1.8mm, and pitch of holes is 6 ~ 15mm.
Still more preferably, described Conic nozzle aperture is 1.0 ~ 1.4mm, and pitch of holes is 8 ~ 12mm.
Again further preferably, described whipping appts rotating speed is 150 ~ 350rpm.
Most preferably, described whipping appts rotating speed is 200 ~ 300rpm.
According to the using method of the Preparation equipment of described particulate state immobilized enzyme, its principal feature is, the Preparation equipment of the particulate state immobilized enzyme described in described using method uses prepares particulate state immobilized enzyme or immobilized cell.
Preferably, described using method is specially:
By immobilization material and thalline or enzyme organism, dissolve batching in advance, then the Preparation equipment of described particulate state immobilized enzyme is metered into through pump, through Hybrid Heating, enter shower nozzle, under the rotation of shower nozzle and under action of gravity, dispersion becomes spherical droplets, and falling into below solidified liquid becomes spherical solid particles.
More preferably, described immobilization material comprises: gelatin, carrageenin, sodium alginate, polyvinyl alcohol, agar, and the mixture of mixing.
Have employed Preparation equipment and the using method of the particulate state immobilized enzyme in this invention, its beneficial effect is: this device can reach mixing and the mixing functions heated, carrageenin, the materials such as gelatin and immobilized enzyme or immobilized thallus are prepared burden separately, carrageenin, gelatin zero pour is all below 50 degree, higher than being liquid state on zero pour, mix with biomaterial (enzyme or cell), through being uniformly mixed and being incubated, flow to Conic nozzle, under the Conic nozzle effect rotated, dispersion becomes spherical liquid, the liquid of ejection starts to be liquid stream, then because surface tension, become drop gradually to fall, fall into below solidified liquid to solidify, cooled and solidified becomes solid, particulate state immobilized enzyme or immobilized thallus can be obtained.
