Sugar boiling automatic control device

Abstract

An automatic control device for sugar cooking, which is a device for automatically controlling several main parameters of a sugar cooking tank, including a vacuum degree control module, a massecuite hammer control module, a heating steam pressure control module and a sugar cooking tank liquid level control module. Control module, in which the vacuum degree control is to measure the vacuum degree of the sugar cooking tank through the transmitter, and adjust the circulating water regulating valve at the inlet of the condenser with DCS to control the vacuum degree; the massecuite brix control is to measure the brix of the syrup through a hammer , the feed valve, water inlet valve and sugar cooking time are controlled by DCS, the heating steam pressure control is to measure the steam pressure of the sugar cooking tank through the pressure transmitter, and the DCS is used to control the amount of heating steam entering the sugar cooking tank; the liquid level of the sugar cooking tank The control is to measure the liquid level of the syrup in the sugar cooking tank through the liquid level transmitter, and the DCS controls the feeding and water inlet valves of the sugar cooking tank. The invention realizes fully automatic sugar cooking, effectively improves the reliability and economic benefits of sugar cooking control, greatly reduces the consumption of water and steam, reduces misoperation, reduces the accident rate, and improves sugar output.

Problems solved by technology

[0002] For a long time, sugar enterprises have only paid attention to the economy of initial investment, and the investment in automation of the production process is very limited. Only equipped with on-site thermometers and pressure gauges, the hammer control of syrup relies more on the experience of the operator, resulting in poor controllability and low reliability. It often occurs under the same operating conditions during the production process. Different quality products are obtained due to human factors, which consumes a lot of water and steam, takes a long time, and is easy to cause misoperation due to different reasons, and the accident rate is high
