The utility model relates to acorn shell -peeling technical field, and disclose a kind of acorn shell -peeling complete assembly assembly line, including support frame, the inside fixed connection of support frame has shell -peeling cover, the bottom end of shell -peeling cover is set as opening, the top of shell -peeling cover is fixedly connected with feed hopper, the bottom end of shell -peeling cover is fixedly connected with several blanking roll, blanking clearance is formed between several blanking roll, the inside of shell -peeling cover is provided with shell -peeling mechanism, the inside of support frame is provided with the screening mechanism located below shell -peeling cover, and the driving mechanism for driving shell -peeling mechanism and screening mechanism action is set on support frame, shell -peeling mechanism includes shell -peeling shaft, the inside of shell -peeling cover is rotatably connected with two shell -peeling shafts, the outside of two shell -peeling shafts is fixedly connected with two shell -peeling rollers, the utility model is set to shell -peeling mechanism, screening mechanism and driving mechanism, driving mechanism can simultaneously drive shell -peeling mechanism and screening mechanism action, so that shell -peeling and screening link integration, reduce manpower cost, save floor area.

The utility model discloses a low temperature extrusion device relates to machinery technical field, including shell 1, shell 2 and feed pipe, shell 1 and shell 2 interiors respectively along respective length direction are equipped with rotating groove, shell 1 and shell 2 are both equipped with conveying mechanism, conveying mechanism includes: the rotating shaft, be horizontally provided in shell 1, be equipped with the rotating groove in shell 1, be equipped with the rotating groove in shell 2, be equipped with the rotating groove in shell 1, be equipped with the rotating groove in shell 2. The axial direction of the rotating shaft is consistent with the length direction of the shell I, the outer arc wall of the rotating shaft is sleeved with a conveying blade and a stirring blade, and the section of the conveying blade in the radial direction of the rotating shaft is spiral; according to the acorn extruding device, low-temperature nitrogen is injected into the second shell through the nitrogen making unit, due to the inertia and drying characteristics of the nitrogen, heat generated in the acorn extruding process can be effectively absorbed and taken away, direct cooling is achieved, acorns are prevented from going bad due to high temperature, and the nitrogen absorbing heat in the second shell returns into the first shell through the backflow pipe; and the preliminarily transported acorn is pre-cooled, so that the utilization rate of nitrogen is increased, the energy consumption is reduced, and meanwhile, the cyclic utilization of heat is realized.

The application discloses a kind of optimization methods of Mongolian oak acorn starch extraction process, belong to the optimization method field of acorn starch extraction process.The application uses acorn starch as raw material, the influence of NaOH mass fraction, solid-liquid ratio, ultrasonic time and ultrasonic power four factors on acorn starch extraction effect is investigated by single factor experiment, and using response surface Box-Behnken analysis method is carried out to the extraction process optimization, and the best extraction condition is determined.According to actual situation adjustment parameter is: sodium hydroxide mass fraction 0.33%, solid-liquid ratio 1:12 g / mL, ultrasonic time 36 min, ultrasonic power 310 W.Under the condition, the average yield of acorn starch is 77.41%, and is similar to theoretical value.The yield of acorn starch prepared under the preparation condition of the application is 77.41%, compared with traditional alkali method, and is increased by 25.98%.The microporous starch prepared from acorn starch under the application has good adsorption performance, and can be widely applied in food, chemical and other fields as adsorbent material.
