Filling device and method for feed enzyme preparation powder

Abstract

The invention discloses a filling device for feed enzyme preparation powder. The filling device comprises a shell, a liner, a gas collecting hood and a vacuumizing pipe. A cavity is formed in the shell, the upper end of the shell is provided with a feeding end communicating with the cavity, and the lower end of the shell is provided with a discharging end communicating with the cavity. The discharging end is provided with a material control mechanism used for controlling connection and disconnection. The liner is arranged in the cavity of the shell and is of a hollow structure, and a liner vent hole is formed in the liner and connected with an external negative pressure pump pipeline. The gas collecting hood is arranged on the periphery of the shell and connected with an inert gas source pipeline. A shell vent hole is formed in the portion, covered with the gas collecting hood, of the shell, and a gas passing channel is formed between the shell vent hole and the liner vent hole and communicates with the feeding end and the discharging end. The vacuumizing pipe is arranged at the discharging end. The invention further provides a filling method utilizing the filling device. The filling device and method aim at removing the impurity atmosphere of a feed enzyme preparation and then conducting filling and vacuumizing treatment, and therefore the storage and quality guarantee period of the feed enzyme preparation is prolonged.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a filling device and a filling method for feed enzyme preparation powder. Background technique [0002] Feed enzyme preparation is a kind of feed additive, which can improve the digestion and utilization of feed by animals, or improve the metabolic performance of animals and add enzymes to feed. [0003] The enzymes used in the feed produced by our company are usually xylanase, cellulase, β-glucanase, protease, amylase, etc., which are mixed with some Chinese herbal medicine powder and packaged. When feeding, the enzyme preparation can be mixed into the basic food, so as to improve the production performance of livestock, improve immunity and other effects. However, when the existing feed enzyme preparations are packaged during the production process, they are simply bagged and vacuumized, and the impurity atmosphere such as oxygen cannot be effectively eliminated. When ...

Problems solved by technology

However, when the existing feed enzyme preparations are packaged during the production process, they are simply bagged and vacuumized, and the impurity atmosphere such as oxygen cannot be effectively eliminated. When stored for a long time, it will still cause deterioration and affect the performance of the enzyme. This problem needs to be solved urgently
