  • Publication number: 20200347154
    Abstract: A method for the production of empty pullulan capsules eliminate the need to dry pullulan solid product, thereby reducing the equipment cost and energy consumption. The pullulan raw material production can be linked directly with the capsule production to provide a unique approach for empty capsule formation. The purified pullulan fermentation fluid can be directly used in capsule preparation, thus removing the need for a melting process. On the one hand, the method may decrease material consumption, save the cost of equipment and labor, reduce production time and increase productivity. On the other hand, the method may reduce the fluctuating of raw material quality in the re-melting process and guarantee a more stable capsule production and quality.

  • Patent number: 10798890
    Abstract: An eccentric swinging stepwise rollback-type reel sprinkling irrigation machine includes a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a water turbine gearbox, an eccentric swinging mechanism, an upper caliper, and a lower caliper. The upper caliper and the lower caliper are clamped to be mounted on the locking channel. A water turbine is used in the eccentric swinging stepwise rollback-type reel sprinkling irrigation machine to drive the eccentric swinging mechanism to realize an eccentric swing, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

  • Publication number: 20200281135
    Abstract: The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

  • Patent number: 10674684
    Abstract: A boat-shaped sprinkler irrigation machine is adapted for large-scale farm irrigation canals, and includes a hull, a traveling propulsion device, a sprinkler irrigation device, and an electric control device. A sprinkler irrigation auxiliary support mechanism is disposed on the hull, and comprises support legs and support roller groups. The support legs are symmetrically disposed on left and right sides of the hull, and top ends of the support legs are mounted on the hull. The support roller groups are mounted on bottom ends of the support legs. The support roller group comprises support rollers. The sprinkler irrigation device comprises a self-priming pump, a sprinkler frame, and a sprinkler gun. The sprinkler frame is fixedly mounted on the hull in a position corresponding to a symmetrical center of the support legs, and the sprinkler gun is fixedly mounted on the sprinkler frame by means of an adjusting assembly.

  • Patent number: 10350568
    Abstract: A membrane-forming composition, soft and hard capsules prepared based on the composition and the preparation methods are described. The membrane-forming composition includes pullulan polysaccharide, gellan gum, amino acid moisturizing agent, anti-hygroscopic agent and so on. It is suitable for the fabrication of hard or soft capsules. The membrane-forming composition can gelate without alkali metal ions. It has a high moisture retention rate which makes it not easy to take up moisture and turn soft in high humid environment, and it will not turn yellow during long time storage. Furthermore, the membrane-forming composition is made up of pure natural materials.
