Method for clarifying liquid substance by using chitosan and carrageenan

The invention discloses a method for clarifying a liquid substance by using chitosan and carrageenan, and belongs to the technical field of food processing. The method comprises the following steps of: adding solution of chitosan and solution of carrageenan into the liquid substance to be clarified; mixing the solution of chitosan, the solution of carrageenan and the liquid substance to generate a floccule when the solution of chitosan is contacted with the solution of carrageenan in aqueous solution; and adsorbing and embedding macromolecular substances and suspended substances in the liquid substance to be clarified by using the floccule so as to clarify the liquid substance. The method is suitable for clarifying liquid beverage, such as fruit and vegetable juice containing phenols and protein with different precipitation mechanisms, tea beverage and the like. The method clarifies the liquid substance by using the chitosan and the carrageenan, so that the method can solve the problems of single function of a clarifier, long time consumption, high equipment investment, not high enough processing clarity and low solubility of the clarifier existing in the conventional clarification method; and the method has the advantages of little equipment investment, simple operation process, low price of raw materials, high clarifying speed, good effect and avoiding affecting the quality and flavor of a product and the like.

Piracetam freeze-dried powder injection for injection and preparation method thereof

The invention discloses a preparation method of a piracetam freeze-dried powder injection for injection. The preparation method comprises the following steps: 1, adding piracetam into injection water to dissolve, adding 0.05% active carbon to stir for 30 minutes at the room temperature and filter, subsequently filtering the injection water into a filtrate A through a filtration membrane with micro pore diameter being 0.22 micron; 2, detecting PH value of the filtrate A in the step 1, carrying out freeze drying on the filtrate A with the PH value meeting the injection requirements in a freeze dryer, namely putting a tube-type bottle filled with the filtrate A on a plate layer of the freeze dryer to carry out heat preservation for 6-7 hours at the temperature being 45 DEG C below zero; opening a vacuum pump, increasing the temperature of the plate layer to 0 DEG C and carrying out heat preservation for 30 hours when a vacuum degree is less than 10 Pa, increasing the temperature of the plate layer to 35 DEG C and carrying out heat preservation for 30 hours when the temperature in the tube-type bottle is close to the temperature of the plate layer, ending freeze-drying to prepare the freeze-dried powder B when the temperature in the tube-type bottle reaches 35 DEG C; (3) crushing the freeze-dried powder B in the step (2) in the environment with the humidity being less than 50%, sieving powder through a 30-mesh sieve after crushing, and carrying out aseptic packaging, bundling cover and packaging.

Fixedly-assembling body

The invention discloses a fixedly-assembling body. The fixedly-assembling body comprises a body, a driving device, a guide device, a clamping mechanism and a copper tube holding device. The driving device is formed by a hydraulic air cylinder. The guide device comprises a guide rail and a supporting frame, and a connecting hole is formed in the supporting frame. An output shaft of the hydraulic air cylinder is connected with the front end of a core rod, and the back end of the core rod penetrates through the connecting hole. The clamping mechanism comprises a clamping guide device fixing base and a clamp forcep set. Driving control optoelectronic switches are installed on the left side of the guide rail and matched with a first induction generator. A driving air cylinder is correspondingly connected to clamping forceps and electrically connected with clamping control optoelectronic switches, and the distance between every two adjacent clamping control optoelectronic switches are equal to the distance between every two adjacent clamping forceps. The copper tube holding device is arranged at the back end of the clamping mechanism, and a clamp forcep holding connector is formed in the copper tube holding device. The fixedly-assembling body has the advantages of being high in machining accuracy, good in product stability, convenient to use, wide in application range and low in manufacturing cost.
