The invention discloses a food sensory evaluation device and method capable of synchronously collecting vision and mouse operation, and belongs to the technical field of food sensory digital evaluation. The device comprises a telescopic experiment table, a display screen, a visual behavior capture instrument, a food heat preservation pad, a mouse, a synchronous control unit and the like, and can synchronously collect eye movement tracks and mouse operation data of a testee under the condition of constant temperature. The method comprises the steps of constant-temperature control, eye movement collection, mouse operation, synchronous collection, data association verification and result output, and the data validity is verified by calculating the matching degree of pupil staying time and mouse operation duration. According to the method, temperature fluctuation and subjective deviation are effectively overcome, objectivity, accuracy and repeatability of food sensory evaluation are improved, and the method is suitable for multiple application scenes such as food research and development, quality control and market research.

The present application relates to the field of food research and development supporting facilities, in particular to a high-efficiency draining device for black sugar preserved plum research and development and a use method thereof. The draining device comprises a container assembly, a disturbance dehydration assembly, a blowing and water removal assembly, and a negative pressure drying assembly. The disturbance dehydration assembly is arranged in the container assembly, and the blowing and water removal assembly and the negative pressure drying assembly are both connected with the container assembly. The present application utilizes the slow reciprocating lifting of the middle part of the net bag of the disturbance dehydration assembly and the high-frequency vibration of the support assembly to make the plum in the net bag swing and roll back and forth while also shaking up and down. The blowing and water removal assembly blows the plum with slightly hot air through the air nozzle to remove the water, and the negative pressure drying assembly is used for drying, to realize all-around flexible disturbance draining, strengthened air drying, and negative pressure drying. The small amount of plum for research and development can quickly drain the water and eliminate the residual water stains without affecting the integrity of the plum, which can meet the timeliness, economy, and trial production effect of small amount of trial production during research and development.
