The invention discloses a novel horse meat product and a preparation method thereof. The method comprises the following steps: with low-fat and high-protein horse meat as a main material, putting a container into a magnetic field of which the voltage is + / -2kv to + / -8kg and the environment temperature is 0-4 DEG C, and pickling for 16-18 hours; carrying out ultrasonic treatment in an ultrasonic generator of 1500W and 40kHz for 30 minutes, and carrying out tendering treatment; carrying out primary air drying, and preparing a unique sauce, wherein the sauce is prepared from the following raw materials in percentage by weight: 14%-16% of fenugreek powder, 14%-16% of red chilli powder, 9%-11% of minced garlic, 9%-11% of cumin powder, 2%-4% of star aniseed powder, 2%-3% of seed powder of Chinese prickly ash and 40%-50% of water in a full mixing manner; and tumbling the prepared sauce with the primarily aired meat product for 30 minutes, carrying out secondary air drying, cutting into slices, packing and preparing to obtain the novel horse meat product. The preparation method has typicality and uniqueness in the aspects of volatile flavor compounds and preparation of the unique and novel horse meat product, and has a wide practicability and value.

The invention provides a processing method for improving the quality of instant chicken feet by ultrasonic combined with electron beam cold sterilization, and relates to the technical field of sterilization and freshness preservation of poultry machining and electronic accelerators. The processing method comprises the following steps of: thawing, trimming and washing chicken feet; bleaching and washing; boiling; ultrasonically pickling; and packaging and carrying out electron beam sterilization. According to the invention, a novel process of ultrasonic auxiliary pickling is added in a pickling process of the instant chicken feet; the processing method has the effect that by utilizing cavatition effect of ultrasonic waves, the speed of immersing pricking condiments into inner parts of tissues of the chicken feet is increased, the pickling time is shortened and the integral flavor of the chicken feet is improved; furthermore, the instant chicken feet are treated by the electron beam cold sterilization, and the processing method has the obvious advantages of short sterilization time, no temperature changes and low production cost, and can keep the original pickled flavor of the instant chicken feet to the greatest extent. Therefore, the method can improve the flavor quality of the instant chicken feet and can shorten the manufacturing and processing periods; the aims of rapidly sterilizing and prolonging the quality guarantee period of products are achieved; and finally, the instant chicken feet product with high quality is obtained.

The invention discloses a process for preparing ultrahigh pure quartz sand through a silica raw material. The silica raw material is treated in such procedures to produce ultrahigh pure quartz sand with SiO2 content larger than 99.995% as manual sorting, calcining, water quenching, crushing, magnetic separation, electrostatic separation, ultrasonic pickling, flotation, ultrasonic alkali washing, drying, secondary magnetic separation, high temperature chlorination, dehydroxylation treatment and the like, and organic alkali washing, electrostatic separation, secondary magnetic separation, dehydroxylation treatment and high temperature chlorination are particularly added. The process for purifying quartz sand provided by the invention is obvious in effect, high in product purity, low in production cost increase and capable of meeting the requirements of such industrial production on raw materials as quartz glass, etc.

The invention relates to an electroplating process for an automobile central controller. The electroplating process comprises the steps of pretreatment, nickel preplating, copper replacement, acid copper plating, semi-finished nickel plating, pearl nickel plating, nickel sealing, chromium plating and drying. In addition, acid activation treatment is added before both the steps of semi-finished nickel plating and chromium plating, and acid pickling is added before the step of pearl nickel plating. Meanwhile, an F90R color scheme is selected and used as the color scheme of pearl nickel, and the pearl nickel is formed by mixing K5 with the concentration being 0.06 ml / L and K6Al with the concentration being 0.4 ml / L. The electroplating process for the automobile central controller has the advantages that mixed liquid of copper and sulfuric acid is adopted for copper replacement, so that cleanliness and flatness of the surface of a to-be-plated product are improved; in addition, an acid pickling procedure or an acidification procedure is added before all the plating steps, thus binding force between coatings can be improved, and separation between the coatings is reduced; meanwhile, specific to the A10 automobile central controller, the pearl nickel of the F90R color scheme is selected and used; and in the pearl nickel plating process, the concentration requirements of the F90R color scheme always needs to be kept, and thus the color of the product is uniform.

The invention discloses an intensifying reverse osmosis off-line cleaning testing method. Equipment comprises a cleaning water tank, a cleaning pump, a water inlet filter, a testing water tank, a testing pump, a dense water pipe filter, a membrane frame, a pressure container, a pipeline connected with the above devices, a valve and an instrument; an ejecting aerator is arranged on the cleaning water tank to intensify foam generation; the pressure container is aslant installed, which is beneficial for draining of water in a membrane and drying of the membrane to change the surface state of themembrane.
