Feeding mixing equipment

Abstract

The invention discloses feeding mixing equipment. The feeding mixing equipment comprises a material mixing device and a gas control device connected with the material mixing device. The gas control device is used for sucking materials into the material mixing device under a vacuumizing state so as to perform material transferring or mixing. The gas control device comprises a buffer cavity and a filter control part, the filter control part is accommodated in the buffer cavity and arranged between the material mixing device and the gas control device, the filter control part prevents the materials in the material mixing device from being sucked back into a vacuumizing device, and the filter control part can be opened or closed in a multi-angle manner and is convenient to clean. The feeding mixing equipment has the advantages that the problem that a traditional filter screen is difficult to clean is solved, and the cleaning and verification requirements of sterile medicine with high sanitation level are satisfied; the included angle between each material inlet of the feeding mixing equipment and the material mixing cavity is 50-85 degrees, the opening directions of the two material inlets are opposite, materials can be evenly mixed, and the mixed materials can keep the original particle form and performance to the maximum extent.

Description

technical field [0001] The invention belongs to the field of material transmission, in particular to a material feeding and mixing equipment. Background technique [0002] In chemical, pharmaceutical, food and other fields, material transfer is an indispensable process for liquid and powder material transfer and mixing. [0003] The current material transmission technology mainly adopts high-level differential pressure transmission, pump mechanical transmission, gas pressure transmission, vacuum suction and other methods, but these processes have certain limitations. [0004] Among them, the pressure transmission of high level difference mainly depends on the material under the action of high level difference. This method is relatively low in transmission speed and poor in mixing ability, and additional mechanical mixing devices are required to mix the transported materials and increase equipment space taken up. [0005] The mechanical transmission of pumps is suitable for...

AI Technical Summary

Problems solved by technology

However, for the cleaning of the equipment, it is necessary to set up additional equipment, and in many existing gas pressure feeding and vacuum suction processes, the problem of material retention has not been well overcome, which is very important for the aseptic requirements of the pharmaceutical industry Higher production, clearly room for improvement

[0007] Furthermore, in some material mixing devices currently using vacuum suction, the movement path of the material in the material mixing device is usually scattered and difficult to control. After vacuum mixing, it is easy to cause the material particles to break, change their particle shape, and affect the quality of the material. Its performance, the debugging process of the mixed process is more difficult
