The invention provides a preparation process of blueberry concentrated juice with high content of anthocyanin. According to the preparation process provided by the invention, pectase is adopted for performing enzymolysis on blueberry pulp, chitosan is adopted as a clarifying agent for obtaining clear blueberry juice, a decompression concentration process is adopted for preparing the blueberry concentrated juice, and microwave sterilization is adopted for sterilizing the blueberry concentrated juice. The preparation process comprises the following steps of: selecting blueberry fruits in vaccinium ashei gardenblue species; extracting the blueberry juice, and adding the pectase to perform the enzymolysis on the blueberry pulp; clarifying the blueberry juice, and adding the chitosan as the clarifying agent for obtaining the clear blueberry juice; concentrating the blueberry juice, and adopting the decompression concentration to obtain the blueberry concentrated juice; and performing sterile filling on the blueberry juice, and adopting the microwave sterilization to sterilize the blueberry concentrated juice, wherein the content of soluble solids in the blueberry concentrated juice is 60%-75%, and the content of the anthocyanin is 1.925g / L-3.384g / L. The preparation process provided by the invention can not only effectively prevent the loss of the anthocyanin in the blueberry concentrated juice, but also shorten the concentration time, control the production cost of the preparation process and effectively protect color, luster, fragrance and other sensory qualities of the blueberry juice.

The invention belongs to the technical field of electrochemical processing of metal materials, and discloses a test method for the electrolyte used in the electrolytic grinding of high-speed steel roll materials. The electrolyte obtained by using the method is calculated by mass percentage: sodium sulfate 2%~8%, phosphoric acid Sodium dihydrogen is 20%, and the balance is deionized water; the method also uses an electrolyte liquid supply system for electrolytic grinding of high-speed steel roll materials, which includes processing power supply, grinding wheel, cathode tool, water tank, motor, Hydraulic pumps, electrolytic reaction tanks, filters, tee pipes, solenoid valves, safety valves, pressure reducing valves, pressure gauges, throttle valves, electromagnetic flowmeters, modification devices and chillers. The water tank is connected with liquid level switches, filter screen, PH detector, heater, temperature sensor, liquid level gauge, liquid unloading valve and water tank cover; the present invention solves the problem of low processing efficiency, high processing cost and surface quality of the prior art mechanical grinding processing and repairing high-speed steel rolls Poor problem, used for electrolytic grinding of high-speed steel roll material.

The invention discloses a multi-degree-of-freedom submerged-arc furnace opening and plugging machine based on cutting type opening, which comprises a rotary cutting type opening machine, a plugging machine and a multi-degree-of-freedom adjustable type platform shared by the rotary cutting type opening machine and the plugging machine. The opening machine is of a rotary cutting type structure; a rotary cutting device, a propelling device and a telescopic arm are arranged on the opening machine; the propelling device propels the rotary cutting device to carry out feeding operation on the telescopic arm; and the multi-degree-of-freedom adjustable type platform is equipped with an amplitude varying device, a lifting device and a travelling device. According to a real-time position of a furnace hole, multi-degree-of-freedom position adjustment of each station is realized by virtue of lifting of the lifting device, angle increase and decrease of the amplitude varying device, extension and retraction of the telescopic arm and ring-shaped displacement of the travelling device; and the rotary cutting type opening is used to replace drilling of a conventional pneumatic or hydraulic rock drill, so that cost is reduced, and opening and hole-forming quality is improved.
