The present application belongs to the technical field of investment casting, and particularly relates to a manufacturing process of a impeller shell. The manufacturing process of the impeller shell comprises the following steps: 1) preparing a wax mold; 2) preparing a surface layer shell; 3) preparing a back layer shell; 4) sealing the shell with slurry; 5) dewaxing; and 6) baking. The manufacturing process of the impeller shell has the characteristics of short production cycle, low production cost, good shell removal, high finished product rate and the like, and improves the casting quality of the castings containing the impeller with a runner width less than 4 mm in the production of the casting industry.

This invention relates to a method for shelling camellia oleifera fruits. The method involves using a low-temperature airflow to treat the fruits, causing the fruit's hilum to crack at a distance of 2-10 mm. Mechanically assisted shelling is then performed, followed by sieving to obtain camellia oleifera seeds. The low-temperature airflow refers to an airflow with a temperature ≤50℃. This invention provides a novel approach to shelling camellia oleifera fruits, and the described process promotes shelling more gently and effectively.

The invention relates to the technical field of rice processing, in particular to an automatic rice processing production system which comprises a silo, a conveying set, a motor, a support, a shell, a sleeve, a first-stage impeller, a second-stage impeller, a third-stage impeller and a discharging plate, the shell comprises a material conveying shaft and a discharging opening, the material conveying shaft is fixedly connected to the inner bottom of the shell, the sleeve is connected to the material conveying shaft, and the first-stage impeller, the second-stage impeller, the third-stage impeller and the discharging opening are arranged in the silo. The first-stage impeller, the second-stage impeller and the third-stage impeller are all installed on the sleeve, the three discharging plates are located between the first-stage impeller and the second-stage impeller, between the second-stage impeller and the third-stage impeller and between the third-stage impeller and the inner bottom of the shell correspondingly, and the discharging openings are located in the downward inclined sides of the discharging plates. A first-stage screen and a second-stage screen are respectively arranged in the centers of the first-stage impeller and the second-stage impeller; according to the centrifugal rice huller, the multiple stages of impellers are arranged to conduct step-by-step hulling on rice with different hulling difficulties, and the effect of improving the hulling uniformity of the centrifugal rice huller is achieved in the mode that the radial length of the centrifugal area of the impellers is shortened.
