Abstract: A fast disintegrating thermally gelling hydroxypropyl methylcellulose (Hypromellose, HPMC) empty capsule can be formed from HPMC 2910 that has a methoxyl content of 27.0% to 30.0% (w/w) and a hydroxylpropoxyl content of 7.0% to 12.0% (w/w). Except for adding a small amount of opacifier and/or colorant, according to customer requirements, the composition can be free of any plasticizer, moisturizing agent, stabilizer, coagulant and other auxiliary materials. The resulting capsule dipped by thermal gelation method has no cracks or wrinkles. The resulting capsule exhibits rapid disintegration release, independent of any dissolution medium, that is significantly faster than capsules dipped by thermal gelation using Hypromellose 2906.

The empty hard capsule includes the following components: 82-89 wt % of pullulan having a pH of 6-7, 1-1.4 wt % of gelling agent, 0.8-1.4 wt % of coagulant aid, 0.01-0.04 wt % of humectant, 0.01-0.04 wt % of surfactant, and 10-14 wt % of purified water. The preparation method for the pullulan empty hard capsule includes: weighing the components; dissolving the gelling agent, the coagulant aid, the humectant, the surfactant, a light-screening agent, a food coloring with 80-90° C. purified water, putting the dissolved substances into a gel dissolving barrel, stirring till the gelling agent is dissolved, adding the pullulan having a pH of 6-7 while stirring, after the pullulan is completely dissolved, cooling, preparing a capsule by means of a glue dipping method, and drying.

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.

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.
