The process of extracting effective component from plant material includes crushing solid plant material mechanically, mixing with proper amount of chemical assistant, and extracting the effective component with water or ethanol. In the process, mechanical crushing of solid plant material produces micro shearing in the material interface and breaks cell wall to expose fresh cut surface, and the chemical assistant produces mutual adsorption with effective component, so that the process can alter the microscopic performance of the effective component and raise the leaching rate to 80-400 %. The present invention has shortened extraction period, high extraction efficiency, high extraction specificity, high selectivity, minimized organic solvent consumption and environment friendship.

The invention relates to an ore extraction and transfer device. The ore extraction and transfer device comprises a box and a first driving device; the first driving device is used for driving the boxto move so as to transport ores to an appointed place; a feed port is formed in the top of the box; and an ore crushing mechanism is arranged in the box. The ore extraction and transfer device has thefollowing beneficial effects: the ore crushing mechanism is arranged in the box, so that the ores can be primarily crushed during loading in the box and transporting, the subsequent crushing time canbe shortened, and the working efficiency is improved; and meanwhile, large ores are crushed beforehand, so that the problem of easiness in damage of the box caused by huge collision to the box by thelarge ores due to bumpy roads can be prevented.

The invention provides a pulverizer and a powder production line comprising the same. The pulverizer comprises a second-level pulverizing unit. The second-level pulverizing unit comprises two communicated pulverizing cavities, a first-level pulverizing cutter set, a second-level pulverizing cutter set and a feeding sloping plate, wherein the first-level pulverizing cutter set and the second-level pulverizing cutter set are arranged in the pulverizing cavities respectively. A feeding inlet is formed in the top wall of the pulverizing cavity containing the first-level pulverizing cutter set. The feeding sloping plate is connected to the side edge of the feeding inlet. A second-level screen is arranged on the side wall of the lower half portion of the pulverizing cavity containing the second-level pulverizing cutter set. The powder production line comprises a conveying mechanism, the pulverizer, a cyclone separator, an air seal machine, a screening machine and a cartridge filter which are connected in sequence. When the pulverizer enters the pulverizing cavities, a downward resultant velocity is generated through the speed of the pulverizer and the linear speed of the tail end of a blade, and it is guaranteed that the cutter sets can be used for effectively grabbing materials. Furthermore, through the design of the distance between the tail end of the blade and the inner wall of each pulverizing cavity and a friction arc plate, the materials are effectively collided, rubbed and pulverized in the pulverizing cavities, and pulverizing time is shortened. The powder production line is smooth in production, free of dust, good in pulverizing effect, and short in time consumption.

The invention relates to a separation and purification method of composite amino acid, and particularly relates to a method for separating and extracting the composite amino acid from hibiscus syriacus leaves. The method comprises the following steps of: (1) pretreating; (2) ultrasonically treating; (3) decoloring; (4) removing impurities; (5) purifying; (6) dissolving a crystal, adding active carbon, stirring, filtering, placing into a refrigerator for filtration, precipitating an amino acid, and drying to obtain a composite amino acid crystal. The method disclosed by the invention can be used for extracting the composite amino acid from the hibiscus syriacus leaves by jointly acting on the hibiscus syriacus leaves through a complex enzyme and an ultrasonic wave, is moderate in enzyme acting condition and plays a wall-breaking role, namely a role of enabling the amino acid contained in the hibiscus syriacus leaves to be thoroughly dissolved. According to the invention, an ultrasonic wave extracting process is a physical process, no chemical change is generated in the extracting process, and a leached biological active substance is kept unchanged within a short time, so that the crushing time is shortened.

The invention relates to an eight-shaft synchronous compounded rubber cutter, which belongs to the technical field of the waste tire recovery device, and solves the problems of low output of recovery and crushing, large power and labor consumption and long technological flow of waste rubber radial tires in the prior art. The eight-shaft synchronous compounded rubber cutter comprises a feeding mechanism, a crushing mechanism, a power and driving mechanism and a rack, wherein the feeding mechanism comprises a feeding drive roll and a feeding driven roll; a primary cutting knife roll and a primary cutting press roll are arranged on one side of the feeding drive roll along the material conveying direction; a combined drive knife roll and a combined driven knife roll are arranged on one side of the primary cutting knife roll along the material conveying direction; a material conveying drive roll and a material conveying driven roll are arranged on one side of the combined drive knife roll along the material conveying direction; a knife fixing bar and a circular movable knife roll are arranged on one side of the material conveying drive roll along the material conveying direction. The eight-shaft synchronous compounded rubber cutter has the advantages that the manpower is saved, the work flow is shortened, good crushing condition is provided for the subsequent work flow, the heating of the radial tires can not be caused, and odor, dust and pollution can not be generated.
