Embodiment 1

[0017] Isolate biologically active edible protein from bovine colostrum

[0018] After diluting bovine colostrum with pure water, it passes through a chromatographic separation column packed with some kind of filler particles. The target molecule can be adsorbed by the filler particles and stay in the chromatographic separation column bed, and the non-target molecule with larger molecular weight cannot be adsorbed and is discharged into the remaining liquid collection tank along with the diluent. After the adsorption in the chromatographic separation column is saturated, a certain concentration of NaCl solution is used as the eluent to elute the target substance into the extraction solution storage tank, and then post-processing to obtain the final product.

[0019] Preface

[0020] The "chromatographic separation column operating condition" in the above table is determined by the selected logistics opening sequence. In this example, the adsorption speed is slower than t...

Embodiment 2

[0022] New technology for separating a variety of edible proteins with biological activity from bovine colostrum

[0023] The main difference between the new process and Example 1 is that the three elutions of NaCl solution of different concentrations are used to replace the single elution in Example 1, so that three products can be obtained and the four-component integrated separation is achieved.

[0024] Use as image 3 The six-element split-flow, four-flow four-component chromatographic separation device shown. First, under the manual control state, make all six chromatographic separation units reach adsorption saturation, and then enter the automatic continuous cycle production. Suppose the time period of automatic switching is Δt, and the control commands for an operation cycle are listed in the following table:

[0025]

[0026] From the comparison of the above two embodiments, it can be seen that appropriately increasing the number of units in the reaction separat...

Abstract

A multi-component split-flow reaction-separation apparatus and its method are disclosed. Its main body is composed of two or more same units. Each unit has two or more pairs of pipelines for the entrance and exit of material. Each pair of pipelines has a switch-type autocontrol valve for switching between two pipelines.

Description

Technical field [0001] The invention relates to a multi-element split-flow reaction separation device and a method thereof. Background technique [0002] In the prior art, the more attention-grabbing continuous separation device is the simulated moving bed, which is described in detail in Chinese patents CN1116088C, CN1087640C, CN1176838A and CN1374146A. In the operation process of these devices, the streams are all cross-flow. That is to say, there are not only circular flow between serial chromatographic columns, but also some straight-through or baffled flows. With the in and out of the flow, the flow rate and flow direction between the chromatographic columns change frequently, and backmixing is easy to occur in the separation bed. And there is cumulative cross-contamination, which affects the purity of product separation and reduces process stability. For some processes with less complex logistics conditions, such as isomer separation, supercritical extraction, etc., the sim...
