The invention relates to a method for extracting astaxanthin in haematococcus pluvialis by adopting an enzymolysis method and a grinding method through an organic solvent, belonging to the field of algal pigment extraction technology. The enzymolysis time for extracting astaxanthin by adopting the existing enzymolysis method is generally more than 15 hours, and the whole extraction process only needs 3-6 hours by adopting the method through assisting the extraction of the organic solvent while grinding in the enzymolysis process, so that the time can be shortened by 57-78%, and the time cost can be greatly saved. The method comprises the steps of carrying out enzymolysis by adopting pectinase, wherein the enzymolysis pH value is 4.0-6.0; firstly drying the enzymolysis liquid, and then extracting with ethyl acetate. The extraction rate can achieve more than 97% by matching pectinase enzymolysis with specific grinding conditions as well as specific organic solvent extraction, and the purity of the obtained astaxanthin product can achieve more than 16.9%, namely that the extraction rate and purity of the astaxanthin can be further improved under the condition of greatly shortening the extraction time.

The invention discloses raw material crushing equipment for production of Longquan celadon and a using method thereof. The raw material crushing equipment comprises a shell, a grinding cylinder, a supporting base, a base, a fixing base, a releasing cylinder, a driving device, a discharging cylinder, a grinding motor and a centralizing device, wherein a first opening is formed in one side of the shell, the grinding cylinder is located in the shell, and grinding beads are arranged in the grinding cylinder. One side of the grinding cylinder is fixedly provided with a feeding cylinder, the end, away from the grinding cylinder, of the feeding cylinder is rotationally connected with the supporting base, the bottom of the supporting base is fixed to the base, a second opening is formed in the side, far away from the first opening, of the shell, the end, far away from the feeding cylinder, of the grinding cylinder is fixedly provided with a rotating shaft, and the rotating shaft penetrates through the second opening and is rotationally connected with the fixing base. According to the raw material crushing equipment for production of the Longquan celadon and the using method thereof, a partof ground raw materials can be output from the discharging cylinder, so that the separation of the ground raw materials from the raw materials which are not subjected to grinding is realized, and thegrinding efficiency of the raw materials is improved.

The invention provides a method for grinding to form powder by using a steam-exposition assisted konjac wet method. According to the method, the problems that in the technology for producing the power by using konjac, the purity of products processed by adopting a dry method is not high, a wet method process season is short, the cost is slightly high, and the like are solved. Due to the adoption of steam-exposition assistance, the consumption of a protecting agent in the technology of producing the powder by using the konjac wet method is reduced, energy consumption of the production process is reduced and the yield and the purity of refined powder are improved. The method comprises the steps of pretreatment of the konjac as a raw material, steam-exposition treatment of the konjac, steam-exposition konjac wet-method grinding and the like. The method has the advantages that: due to the use of steam exposition, on one hand, cell walls are damaged, and on the other hand, konjac glucomannan is partially degraded into oligosaccharide, and thereby the contacted area of the protecting agent and the konjac glucomannan is increased, the purity of the konjac glucomannan in konjac powder is improved, and the functional value of the konjac powder is increased.

The invention discloses a powder spraying three-pass drier. The powder spraying three-pass drier comprises a roller drier body. Communicators are installed at the two ends of the roller drier body. The communicator located on the left side of the roller drier body is communicated with a powder burning furnace through a material conveying pipe, and the communicator located on the right side of the roller drier is communicated with a slag separator through a material conveying pipe. The slag separator is communicated with a draught fan through a material conveying pipe. The draught fan is communicated with a dust remover through a material conveying pipe. The dust remover is connected with a dry wood powder collecting device and a powder sending draught fan device respectively through material conveying pipes. The powder sending draught fan device is communicated with the powder burning furnace through a material conveying pipe. The material conveying pipe between the roller drier body and the powder burning furnace is provided with a wet wood powder feeding device communicated with the corresponding material conveying pipe. According to the powder spraying three-pass drier, it is ensured that wood powder can stay in the drier for a long time in the working process, the amount of the wood powder is large, the automation degree is high, slag and dust in the wood powder can be removed, the quality of drying work is improved, meanwhile, the drying work on wet wood powder is achieved, and the three-pass drying efficiency and use value are achieved.
