A method for draining fermenting must from a fermentation tank comprises: a) breaking into chunks a cap that forms in the tank while must ferments in the tank, b) after breaking the cap, mixing the must to homogenize the must and reduce the size of the cap chunks to a size that can pass through a drain of the tank, and c) opening the drain in the fermentation tank to remove the must from the tank. Breaking the cap into chunks includes: a) injecting gas into the must to form a bubble in the must, b) moving the bubble through the must to generate a flow of must within the fermentation tank, and c) shearing a surface of the cap with the generated flow to break the cap into chunks Mixing the must to reduce the size of the cap chunks includes: a) injecting gas into the must to form a bubble in the must, and b) moving the bubble through the must to mix the must.

An ultrasonic homogenizer includes an ultrasonic transducer; an ultrasonic horn that irradiates an ultrasonic wave generated by the ultrasonic transducer; a holder that receives an irradiating surface of the ultrasonic horn; an intake port that is provided on a bottom face of the holder and intakes a mixture liquid into the holder; and an ejection port that is provided on the holder above the intake port and discharges the mixture liquid supplied inside the holder; an opening area of the intake port being smaller than an irradiating area of the ultrasonic horn and the irradiating surface of the ultrasonic horn being disposed above the intake port whereby facing the intake port.

The present invention relates to methods, devices, instruments, processes, and systems for the highly specific, targeted molecular analysis of regions of human genomes and transcriptomes from the blood, i.e. from cell free circulating DNA, exosomes, microRNA, lncRNA, circulating tumor cells, or total blood cells. The technology enables highly sensitive identification and enumeration of mutation, expression, copy number, translocation, alternative splicing, and methylation changes using spatial multiplexing and combined nuclease, ligation, polymerase, and sequencing reactions. Such technology may be used for non-invasive early detection of cancer, non-invasive cancer prognosis, and monitoring both treatment efficacy and disease recurrence of cancer.
