Abstract

The invention discloses a spray characteristic parameter detection device and method. The spray characteristic parameter detection device comprises an integral support rack, a two-dimensional moving unit, a servo motor, a servo control unit, a spray control system, a pulse nozzle, a high-speed camera image acquisition system and a laser particle size analyzer system. On the basis of the device, the spray characteristic parameter detection method comprises the following steps: detecting an outline shape of spray, macroscopic two-dimensional distribution of spray and the flying speed of particles of spray by virtue of the high-speed camera image acquisition system; and detecting the particle size of spray with two-dimensional distribution in a spatial two-dimensional plane travel range by a two-dimensional precise servo driving system based on a laser particle size analyzer according to the outline and the macroscopic two-dimensional distribution of spray on the basis of a spray image acquisition result.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a device and method for detecting spray characteristic parameters in the field of bio-based material forming technology and equipment. Background technique [0002] Packaging is an independent element of the food manufacturing process that brings convenience to people's lives. Green packaging is an important way to achieve sustainable development of the packaging industry and reduce environmental pollution caused by packaging. Edible packaging films and vegetable-based materials are rich in raw materials, sustainable, edible, and pollution-free. It has become a hot spot in the research of emerging packaging field. Vegetable composite paper soybean protein liquid spraying technology adopts the electronic pulse spraying method of protein liquid. By setting the pulse spraying flow rate, air pressure, hydraulic pressure and other related parameters, the protein solutio...
