Abstract

The invention discloses a fluid supplementary food weighing and metering control device, which comprises a supplementary food cup, a valve system, a fermentation tank and a supplementary food tank, and is characterized by also comprising a weighing system and an electronic monitoring system, wherein the weighing system comprises a weighting sensor, a suspension arm, a fixed bracket and a weighing cup, the supplementary food cup is connected with the weighting sensor to weigh the supplementary food in the supplementary food cup, the electronic monitoring system comprises an A / D conversion module, an alarming and display module, a keyboard, a mouse, a touch screen, a comparator, a setter, a CPU and a food supplementation speed controller. As the supplementary food is metered by the weighing device, the device has the advantages of up to 0.5 percent high food supplementation accuracy and providing a reliable guarantee for the optimization and amplification of an industrial fermentation process.

Description

technical field [0001] The invention relates to a fluid feeding metering control device, in particular to a precise fluid feeding weighing metering control device for fermentation process control. Background technique [0002] The existing metering devices are divided into continuous metering and discrete metering. Continuous metering uses electromagnetic flowmeters, mass flowmeters, etc., which have high precision, but are more expensive. If there are air bubbles in the feed liquid, the accuracy will be reduced. Especially in the fermentation industry, expensive continuous flowmeters must be used. regulator valve. [0003] The "metering cup type" of discrete metering is represented by the "three-valve system", (see figure 1 ), the metering cup type has been popularized and applied in the pharmaceutical industry for many years, and achieved good results. This makes the cup count as a unit of measurement inaccurate. "Three-valve system" as attached figure 1 shown. There...
