While you are raising the pet fish, you shall guarantee to feed them scientifically on time as they are just like the human being, they also eat. At present, the food for pet fish is red worms, baby shrimps, and little shrimp meat. They are usually packed in large-size packs or bottles. While they are easily bring the user many troubles and losses like the nutrients of the red worms lost the freshness, producing germs. Moreover we are not easy to master the amount of food while feeding the pet fish. That is to say they are not packed in a scientific manner. In the foreign countries, they are packed with al-plastic materials in a freeing manner that can overcome the above defects. Therefore our research fellows have repeatedly made experiments. In the end, they have developed innovatively the domestically advanced Absorption and Pouring type fish food packaging-feeding device XSJ Series that have been patented by the state patent administration. Its patent number is 200610008264.77. This Frozen Shrimp has two models, model 250 and model 140. It is integrated mechanic, electric, pneumatic technologies. All the operations are controlled through signals sent off by the sensor switches. It's equipped with PLC program, simplifying the construction, making the blister locking synchronize with it to achieve the feeding the pet fish food. The packed food won't be destroyed in its cells and nutrients, and the products won't be deteriorated in the fridge at 18 below zero for within two years, which can keep the proteins and vitamins in the food from losing, keeping its sound performance of returning to water. Therefore it is popular among the consumers. It is exported to Singapore, Thailand, Malaysia, Indonesia and Hong Kong.
